The three moments when flavor goes in

Give each stage of cooking a job.

1. 1 At the beginning, aromatics go into fat over moderate heat. Onion, garlic, celery, carrot, ginger, scallion whites, leeks, and fresh chiles belong here. They need time and gentle heat to turn sweet and round.
2. 2 In the middle, dried spices, browning, and liquid do their work. This is where searing, roasting, braising, and simmering build depth that no amount of salt can imitate.
3. 3 At the end, off the heat, acid and fresh herbs go in. A squeeze of lemon, a splash of vinegar, a handful of chopped parsley or cilantro or dill. This is also where a small amount of salt does the most.

The American Heart Association names the same tools in plainer terms. It lists onions, garlic, herbs, spices, citrus juices, and vinegars as ingredients that add flavor in place of some or all of the salt, and it lists grilling, braising, roasting, searing, and sautéing as cooking methods that bring out natural flavors so less salt is needed.

Most flat cooking comes from skipping the first and third moments. The onions go in and come out two minutes later, pale and sharp. Nothing acidic or fresh goes in at the end. What is left in the middle is a dish that can only be fixed with salt.

What garlic and onions are actually doing

Aromatics are the base note. Onion cooked gently for 8 to 10 minutes, until it is soft and just starting to color at the edges, tastes nothing like onion that hit the pan 90 seconds ago. The slow version brings sweetness and body. The fast version brings a raw bite that many people then try to cover with salt.

Garlic works on a different clock. It burns in about a minute at the heat that onions enjoy, and burned garlic turns bitter in a way nothing later can undo. Add it after the onion has softened, stir it for 30 to 60 seconds until you can smell it, then add your liquid or your next ingredient.

How you cut garlic changes how strong it tastes. A whole clove, lightly smashed and left in the oil, gives a mild background flavor you can fish out later. Sliced garlic is stronger. Minced or grated garlic is strongest of all, because more of the cut surface is exposed. If a dish tastes harsh, try cutting the garlic larger rather than using less of it.

One label habit matters here. The American Heart Association specifically recommends garlic, and adds the words "not garlic salt." Garlic powder is a reasonable pantry item with no sodium of its own. Garlic salt is mostly salt. The same trap sits in onion salt, celery salt, and many seasoned salts. A separate article in this series covers building a pantry shelf of herbs, spices, and aromatics in more detail.

Heat is a seasoning

Browning is flavor you get for free. When food hits a hot, dry surface and develops color, it also develops taste that was not there before. This is why the American Heart Association lists searing, roasting, and grilling alongside herbs and spices as ways to cut the need for salt.

Three practical habits make browning happen instead of steaming.

1. 1 Dry the surface. Pat chicken, fish, tofu, or mushrooms with a paper towel before they go into the pan. Wet food steams.
2. 2 Give things room. Crowding a pan traps moisture. Two batches with space beat one crowded batch every time.
3. 3 Leave it alone. Food releases from the pan when it has browned. If it sticks, it usually is not ready to turn.

After searing, a small amount of liquid poured into the hot pan will loosen the browned bits stuck to the bottom. Scrape them up with a wooden spoon and they dissolve into the sauce. Wine, broth, tomato juice, citrus juice, vinegar cut with water, or plain water all work. Those browned bits are among the most concentrated flavor in the whole dish, and most home cooks wash them down the drain.

Braising is the slow version of the same idea. Brown the meat or the vegetables first, then cook them partly covered in liquid over low heat for an hour or more. Time does the seasoning. A separate article in this series looks at what roasting in particular does to vegetables.

Acid is the step most home cooks skip

If a dish tastes dull and you reach for salt, try acid first. Lemon, lime, orange, and vinegar all sharpen flavors that have gone soft during cooking. The American Heart Association suggests using fresh lemon juice in place of salt to season fish and vegetables, and lists cider vinegar for salads, vegetables, and sauces. When eating out, it recommends tasting your food first and, if it needs a lift, adding freshly ground black pepper or a squeeze of fresh lemon or lime before reaching for the shaker. Mayo Clinic offers the same advice, naming fresh and dried herbs, spices, and both the zest and the juice of citrus fruit.

Zest and juice are not interchangeable, and using both is the trick worth learning. The colored outer peel carries the aroma. The juice carries the sourness. Grate the zest with a fine grater, taking only the colored layer and leaving the white pith underneath, which is bitter. Zest can go in during cooking. Juice belongs at the end, after the heat is off, because its brightness fades as it cooks.

Vinegars vary in strength and character, so start small. A teaspoon stirred into a pot of beans or a pan of greens, then a taste, then another teaspoon if needed. Rice vinegar and cider vinegar are mild. Distilled white vinegar is sharp. Balsamic brings sweetness along with the acid.

Acid also rescues food that has already been salted. A soup that tastes too salty often tastes balanced again after a squeeze of lemon, because sourness competes for your attention.

Herbs and spices, and when each one goes in

Dried herbs and ground spices want heat and time. Add them in the middle stage, and give them 30 seconds or so in the hot fat before liquid arrives. Warming dried spices in oil is standard practice in kitchens across many cuisines because it softens their raw, dusty edge. Whole spices such as cumin seed, coriander seed, mustard seed, or black peppercorns can be toasted briefly in a dry pan until they smell fragrant, then ground.

Fresh herbs want the opposite. Parsley, cilantro, basil, dill, mint, and chives lose their aroma with long cooking. Stir them in after the heat is off, or scatter them over the plate. Woody fresh herbs such as rosemary, thyme, sage, and oregano are the exception. They hold up to heat and can go in early, on the stem if you plan to pull the stem out later.

The American Heart Association publishes a set of pairings that gives a useful starting map.

1. 1 Basil with fish, lamb, lean ground meats, stews, salads, soups, sauces.
2. 2 Dill with fish, soups, tomatoes, cabbage, carrots, cauliflower, green beans, cucumbers, potatoes, salads, macaroni, lean beef, lamb, and chicken.
3. 3 Rosemary with chicken, veal, lean meatloaf, lean beef, lean pork, sauces, stuffings, potatoes, peas, and lima beans.
4. 4 Thyme with lean meats, especially veal and pork, plus sauces, soups, onions, peas, tomatoes, and salads.
5. 5 Curry powder with lamb, veal, chicken, fish, tomatoes, and tomato soup.
6. 6 Garlic with lean meats, fish, soups, salads, vegetables, tomatoes, and potatoes.

Black pepper deserves a mention of its own. Ground fresh from a mill, it has a heat and perfume that preground pepper has lost. It is the single cheapest upgrade in most kitchens.

Put the salt where you will taste it

Where salt sits in a dish affects how salty the dish tastes. A 2021 review in the journal Nutrients describes changing how a taste ingredient is distributed within a food as one of the practical ways to increase perceived taste without increasing the amount used. In a home kitchen, that translates into a simple habit: salt the surface at the end rather than stirring it all in at the beginning, so your tongue meets it directly.

Several official tips follow the same logic. The American Heart Association recommends cooking pasta, rice, and hot cereal without salt, and tasting food before adding any. The older National Heart, Lung, and Blood Institute guide to the DASH eating plan gives the same advice and adds two more: rinse canned foods such as beans and tuna to wash off some of the sodium, and start by cutting the salt in a recipe in half. The Heart Association puts a number on the rinsing step, saying draining and rinsing canned beans and vegetables can cut the sodium by up to 40 percent.

For a recipe you are not ready to change all at once, the Heart Association suggests combining a lower sodium version of a food with the regular version in equal parts, then adjusting from there. A separate article in this series walks through adapting a family recipe one ingredient at a time.

DASH itself is built on two sodium levels: 2,300 milligrams a day in the standard plan and 1,500 mg in the lower sodium version, which the institute says lowers blood pressure further than 2,300 mg. The 2025 American Heart Association and American College of Cardiology high blood pressure guideline estimates that reducing sodium is associated with a drop of roughly 6 to 8 mm Hg in systolic pressure, the top number, among people with high blood pressure. Your own result depends on where you are starting from and on much else besides.

Your taste for salt is not fixed

Food seasoned to a lower sodium level tastes flat at first. That is a real sensation, not imagination, and it does not last forever.

The best known evidence comes from a 1982 study published in the American Journal of Clinical Nutrition. Young adults ate a reduced sodium diet for five months following a two month baseline period, while a control group ate normally. The amount of salt the reduced sodium group preferred in soup and in crackers dropped, while the control group's preference did not change, and crackers actually tasted saltier to them than before. The authors concluded that preferred salt levels depend on how much salt a person has been eating and can be lowered after intake comes down.

How fast this happens is less settled. The Heart Association says only that it may take some time for your taste buds to adjust. Mayo Clinic suggests that after a few weeks of gradual reduction many people stop missing the salt shaker. The 2021 Nutrients review makes the same point about pacing: gradual reduction allows a person to adapt progressively to a less intense taste. Cutting salt slowly, over weeks, is more likely to stick than cutting it all at once.

One weeknight dinner, layered

Suppose you are cooking chicken thighs with potatoes and green beans.

1. 1 Pat the chicken dry. Sear it in a tablespoon of oil over medium high heat, skin side down, without moving it, until it is deeply browned. Remove it to a plate.
2. 2 Lower the heat. Add a sliced onion to the same pan and cook it for 8 minutes until soft and golden, scraping up the browned bits as it releases moisture.
3. 3 Add 3 cloves of sliced garlic and a teaspoon of dried thyme. Stir for 40 seconds.
4. 4 Pour in half a cup of water or unsalted broth and scrape the pan clean. Add quartered potatoes, return the chicken, cover partly, and cook until the potatoes are tender.
5. 5 Add the green beans for the last 8 minutes.
6. 6 Off the heat, add the grated zest of half a lemon, the juice of that half lemon, a generous grind of black pepper, and a small pinch of salt scattered over the top. Finish with chopped parsley.

Taste after step 6 and before you add anything else. Most of the time, the acid and the pepper have already done what you were going to ask the salt to do.

Potassium, kidneys, and the salt substitute question

The Heart Association recommends eating potassium rich foods regularly, naming sweet potatoes, potatoes, greens, tomatoes, white beans, kidney beans, nonfat yogurt, oranges, bananas, and cantaloupe, and says potassium helps counter the effects of sodium.

Potassium is not the right advice for everyone, and this is where individual guidance matters. The National Institute of Diabetes and Digestive and Kidney Diseases tells people with chronic kidney disease to use spices and herbs rather than salt substitutes, which can be high in potassium, and to limit foods that list potassium chloride on the ingredient label. Mayo Clinic notes that too much potassium can be harmful for people with kidney problems and for people taking certain blood pressure or heart failure medicines that cause the body to hold on to potassium.

If you have reduced kidney function, or take medicines that affect potassium, ask your health care professional or pharmacist before adding potassium rich foods deliberately or using any salt substitute. A separate article in this series covers the questions worth asking first. Nothing in this article requires a salt substitute. Citrus, vinegar, aromatics, herbs, spices, black pepper, and browning add no sodium and no potassium worth counting.

Start with one change tonight. Finish whatever you are already cooking with acid, off the heat, before you taste it.
