Ready to learn how to cook at home? In this blog post I share answers to your top home cooking questions – from a chef’s perspective!
Cooking doesn’t have to be complicated, but there are a lot of little questions that come up every time you prepare a meal.
Should you preheat the pan? When should you add garlic? Should you rinse canned beans? Why does food stick? When should you add salt? What’s the difference between sautéing and simmering?
These are the kinds of everyday cooking questions that can make a big difference in the results you get in the kitchen.
As a chef, these are some of the questions I hear and the things I think about while cooking at home.
Chef Answers 50 Cooking Questions Every Home Cook Has
Here’s my answers to your most commonly asked cooking questions:
Getting Started
1. Do I need to read the entire recipe before I start cooking?
Yes.
Even if you’re familiar with the recipe, read through it before you start.
You may discover that an ingredient needs to be prepared ahead of time, something needs to be at room temperature, or two components need to be ready at the same time.
A few minutes of preparation can prevent a lot of problems once you start cooking.
2. Should I prepare all my ingredients before I start cooking?
Ideally, yes—but you don’t necessarily need to have every ingredient completely prepared and sitting in separate bowls.
Professional kitchens often use the term mise en place, which means having your ingredients organized and ready before you begin.
For home cooking, you can simply make sure you have everything you need, prepare the ingredients that take the longest, and organize the rest so you’re not scrambling while something is cooking.
3. Do I need to preheat my pan before cooking?
Usually, yes.
A preheated pan helps food begin cooking immediately and encourages browning.
If you put food into a cold pan, it can slowly heat up and release moisture rather than developing the browning you’re looking for.
The exact temperature depends on what you’re cooking, but preheating your pan is generally a good habit.
4. How do I know when my pan is hot enough?
It depends on what you’re cooking.
For sautéing, you generally want the pan hot enough that the food begins cooking immediately when it hits the surface.
You can also look at the oil. If it becomes fluid and shimmery, the pan is getting hot.
Don’t let oil smoke heavily. That’s usually a sign that the pan is too hot.
5. Should I put oil in a cold pan or a hot pan?
Either can work, depending on the cooking method and the type of pan.
For many everyday sautéing applications, I prefer adding the oil after the pan has started heating.
This lets you watch the oil and add the food when the pan is ready.
The important thing is not to let the oil overheat and smoke.
Salt & Seasoning
6. When should I add salt?
It depends on what you’re cooking.
Salt can be added at different stages to build flavor throughout the cooking process.
For vegetables, beans, soups, sauces, and grains, seasoning as you cook often produces better results than waiting until the very end.
The important thing is to taste as you go so you don’t accidentally over-season.
7. Should I taste my food while I’m cooking?
Absolutely.
Tasting as you cook is one of the most important cooking skills you can develop.
You’re looking for more than just salt. Ask yourself:
- Does it need more salt?
- Is it too acidic?
- Does it need sweetness?
- Is the flavor strong enough?
- Does it need more seasoning?
You can’t adjust the flavor of a finished meal as easily as you can adjust it while you’re cooking.
8. Why does my food taste bland even when I added salt?
Salt isn’t always the only missing ingredient.
Food can taste flat because it needs acidity, sweetness, herbs, spices, fat, or simply more concentrated flavor.
A small amount of lemon juice or vinegar, for example, can sometimes make a dish taste much more flavorful without adding more salt.
9. When should I add dried herbs?
Dried herbs generally benefit from some cooking time.
Adding them earlier allows their flavors to develop throughout the dish.
However, delicate herbs and spices can lose some of their flavor if they’re cooked for too long, so timing depends on the particular ingredient.
10. When should I add fresh herbs?
Fresh herbs are often best added toward the end of cooking.
Some sturdier herbs can be cooked for longer, while delicate herbs such as parsley and cilantro are often better added shortly before serving.
You can also save some fresh herbs for garnish.
11. Can I substitute dried herbs for fresh herbs?
Usually, yes.
Dried herbs are more concentrated because much of their water has been removed.
A common starting point is using about one-third as much dried herb as fresh, although this varies depending on the herb and recipe.
12. Should I use fresh garlic or garlic powder?
Both have their place.
Fresh garlic gives you a stronger, fresher flavor, while garlic powder distributes evenly throughout a dish and is convenient for seasoning.
They’re not exactly interchangeable because they taste different.
Vegetables & Sautéing
13. Why does my food stick to the pan?
There are several possible reasons.
The pan may not be hot enough, you may not be using enough cooking fat, or you may be trying to move the food before it has had time to brown.
Some foods naturally stick temporarily and then release once they develop a crust.
14. Should I stir vegetables constantly?
Usually not.
Constant stirring prevents food from staying in contact with the hot surface long enough to brown.
Let the vegetables cook for a while before stirring or tossing them.
How often you stir depends on what you’re cooking.
15. Why shouldn’t I overcrowd my pan?
Too much food in the pan creates steam.
Instead of browning, your food can begin to steam and become soft.
If you want good browning, give the food enough room to contact the cooking surface.
Cooking in batches is sometimes better than putting everything into the pan at once.
16. Should I cook onions before garlic?
Usually, yes.
Onions generally take longer to cook, while garlic can burn relatively quickly.
Adding garlic after the onions have started cooking gives it enough time to develop flavor without allowing it to burn.
17. Why did my garlic burn?
Garlic cooks quickly, especially over high heat.
If garlic turns dark brown or black, it can become bitter.
Lower the heat and add garlic later in the cooking process when possible.
18. Should I salt vegetables before or after cooking?
You can do either, depending on what you’re trying to accomplish.
Salting during cooking seasons the vegetables throughout.
Salting toward the end lets you make a final adjustment.
For many vegetables, I prefer seasoning in stages rather than adding all the salt at once.
19. Why are my vegetables soggy?
Excess moisture and overcrowding are two common causes.
If vegetables are packed tightly into a pan, they release water and create steam.
Higher heat, enough cooking space, and avoiding excessive moisture can help vegetables brown instead of becoming soggy.
20. Should I wash vegetables before cooking?
Yes.
Wash fresh produce before preparing and eating it.
For produce that will be peeled, washing the outside first can also prevent dirt and bacteria from being transferred to the inside while you’re cutting it.
Canned & Packaged Foods
21. Do I need to rinse canned beans?
Usually, I recommend it.
Rinsing removes the liquid they’re packed in and can reduce some of the excess sodium.
It also gives you more control over the flavor and consistency of your dish.
There are exceptions: sometimes the bean liquid is intentionally used in a recipe.
22. Do I need to rinse canned chickpeas?
You don’t have to, but rinsing them is often useful.
It removes the packing liquid and can produce a cleaner flavor.
If you’re using chickpeas in a salad, bowl, or recipe where you want them to have a fresh flavor, I generally prefer rinsing them.
23. Should I drain canned vegetables?
Usually, yes, unless the liquid is part of the recipe.
Draining helps you control the amount of liquid and salt you’re adding to your dish.
24. Should I rinse canned corn?
You don’t have to, but you can.
Rinsing removes the liquid and some of the excess salt.
If you’re adding the corn to a dish where you want to control the seasoning, rinsing is a simple option.
25. Should I rinse canned tomatoes?
Usually, no.
The liquid in canned tomatoes is often part of the product and can be useful in soups, sauces, and other recipes.
Whether you drain them depends on the recipe.
26. Can I use the liquid from canned beans?
Yes.
The liquid from canned beans is sometimes called aquafaba and can be useful in certain recipes.
You don’t always need to discard it.
Knives & Food Preparation
27. How often should I sharpen my kitchen knives?
There’s no universal schedule.
How often a knife needs sharpening depends on how frequently you use it, what you’re cutting, your cutting surface, and the type of knife.
If your knife no longer cuts easily and safely, it may be time to sharpen it.
28. What’s the difference between sharpening and honing a knife?
Sharpening removes material to create a new edge.
Honing helps realign the existing edge.
Honing can help maintain a knife between sharpenings, but it doesn’t replace sharpening a genuinely dull knife.
29. Why does my knife crush tomatoes instead of cutting them?
Your knife is probably dull.
A sharp knife should easily cut through the skin of a tomato without requiring excessive pressure.
A dull knife tends to slide, crush, and require more force—which can actually make it more dangerous.
30. Should kitchen knives go in the dishwasher?
I recommend hand washing good kitchen knives.
The heat, detergents, and movement inside a dishwasher can damage knife edges and handles.
Hand washing and drying your knives helps them stay in better condition.
Pasta, Rice & Grains
31. Should I rinse pasta before cooking it?
No.
For standard pasta, you generally want to cook it directly in boiling water.
Rinsing it before cooking removes surface starch that helps with the cooking process and sauce adhesion.
32. Should I rinse pasta after cooking?
Usually, no.
If you’re serving hot pasta with sauce, rinsing removes surface starch that can help the sauce cling to the pasta.
There are exceptions, such as when you’re making a cold pasta salad or a dish where you specifically want to stop the cooking process.
33. Should I add oil to pasta water?
Usually, no.
Oil floating on the surface of the water doesn’t do much to prevent pasta from sticking together.
Instead, use plenty of water, stir the pasta as it begins cooking, and don’t overcook it.
34. Should I salt pasta water?
Yes.
Salt seasons the pasta as it cooks.
It’s much easier to build flavor into the pasta itself than to try to compensate for completely unsalted pasta with sauce later.
35. Should I save pasta water?
Yes, if you’re making a sauce.
Pasta water contains starch released from the pasta.
Adding some of that water to a sauce can help loosen it and help the sauce emulsify and cling to the pasta.
36. Why does my rice turn out mushy?
Too much water is one common cause, but the type of rice and cooking method also matter.
Different varieties require different amounts of water.
Follow the instructions for the particular rice you’re using rather than assuming every type of rice uses the same ratio.
37. Should I rinse rice?
It depends on the type of rice and the result you’re looking for.
Rinsing can remove excess surface starch and may produce less sticky rice.
However, some dishes intentionally benefit from that starch.
Cooking Techniques
38. What’s the difference between sautéing and frying?
The terms can overlap, but sautéing generally refers to cooking relatively quickly in a small amount of fat over fairly high heat.
Frying is a broader term that can include shallow frying and deep frying.
39. What’s the difference between simmering and boiling?
A boil has large, vigorous bubbles throughout the liquid.
A simmer has smaller, gentler bubbles.
Many foods are better cooked at a simmer because vigorous boiling can break them apart or cause excessive evaporation.
40. When should I use high heat?
High heat is useful when you need quick browning, boiling, or rapid cooking.
But high heat isn’t automatically better.
Food can burn on the outside before it has time to cook properly inside.
41. When should I use low heat?
Low heat is useful for gentle cooking, keeping food warm, slowly reducing sauces, and cooking foods that could burn easily.
Learning to adjust the heat as you cook is one of the most important skills in the kitchen.
42. Why does food brown better in a hot pan?
Browning requires the food’s surface to get hot enough for browning reactions to occur.
If the pan is too cool or overcrowded, moisture can keep the food closer to steaming temperature.
A properly heated pan helps you develop color and flavor.
43. Should I cover the pan when cooking?
It depends on what you’re trying to accomplish.
Covering a pan traps steam and moisture, which can help cook food more quickly and prevent it from drying out.
Leaving it uncovered allows moisture to escape and can help with browning and reducing sauces.
44. Should I stir a sauce constantly?
Usually, no.
Some sauces need frequent stirring to prevent sticking or scorching, while others benefit from being left alone to simmer and reduce.
The right answer depends on the ingredients and heat level.
Making Food Taste Better
45. What can I do if my food tastes too salty?
Don’t immediately add more ingredients without tasting first.
Depending on the dish, you may be able to dilute it with additional unsalted ingredients or balance the flavor with acidity, sweetness, or other components.
The best solution depends on what you’re making.
46. What can I do if my food tastes bland?
First, taste it.
Then consider whether it needs:
- Salt
- Acid
- Herbs
- Spices
- Fat
- Sweetness
- More concentrated cooking
A small adjustment can sometimes transform a dish.
47. Why does lemon juice make food taste better?
Acid can brighten flavors and balance rich, salty, or sweet foods.
Lemon juice is one way to add acidity, but vinegar and other acidic ingredients can serve a similar purpose.
You don’t necessarily need a lot. Sometimes just a small amount makes the other flavors stand out.
48. When should I add acid to a dish?
Often toward the end of cooking.
Adding lemon juice or vinegar near the end allows the acidity to remain bright and noticeable.
However, some recipes benefit from adding acid earlier so it becomes part of the overall flavor.
The Most Important Cooking Skill
49. How do I know when food is actually done?
Don’t rely only on the clock.
Recipes give you cooking times as a guideline, but ingredients, pan size, heat level, and equipment can all change the cooking time.
Learn to look at, smell, touch, and taste your food.
For foods that require a specific safe internal temperature, use a thermometer rather than guessing.
50. What’s the most important cooking skill for a home cook?
Learn to pay attention to your food.
Recipes are useful, but they’re not always going to behave exactly the same way in every kitchen.
Learn to recognize:
- What properly heated oil looks like
- What a simmer looks like
- What properly cooked vegetables look like
- When food is browning
- When something is burning
- When a dish needs more seasoning
- When something needs more liquid
- When something needs more time
The more you pay attention while you cook, the less dependent you’ll become on following a recipe perfectly.
Cooking is not just following instructions. It’s learning how to respond to what’s happening in the pan.
Final Thoughts
You don’t need complicated recipes or expensive equipment to become a better home cook.
A lot of good cooking comes down to understanding the small decisions you make every day: when to heat the pan, when to season, when to stir, when to leave something alone, and how to recognize when your food needs an adjustment.
The next time you’re cooking, don’t just follow the recipe. Pay attention to what’s happening.
That’s where you’ll learn the most.
