From mirepoix in France to refogado in Brazil, foundational trinities of aromatic vegetables bring flavor to soups, stews, sauces and other dishes worldwide. Aromatics are vegetables that deliver deep, rounded flavor and aroma when heated or crushed. From garlic and onions to chilies and ginger, each vegetable boasts different health benefits and cooking qualities that make it unique.
To create delicious meals by adding flavor instead of fat, sugar or salt, here are some tips for using aromatics.
- For the best flavor and texture, use fresh aromatics. Frozen ones may be too watery.
- Chop and store aromatics in advance to make meal prep quick and easy during the week.
- Chop veggies for even cooking. Hearty vegetables like carrots may require a smaller chop to soften at the same rate as onions, but larger cubes may be appropriate for a soup or stew that will cook longer.
- Handle hot peppers and onions carefully. The oils from these aromatics can irritate your eyes and nose. Wash your hands before touching your face.
- Don’t weigh down your dish with fats and oils. Sauté or sweat vegetables in small amounts of oil, juice, broth or water. To sweat vegetables, cook them in a tightly covered pot. Vegetables will soften without browning.

Ginger provides vitamin C, magnesium and potassium.
With a mild onion flavor, leeks are best cooked. Enjoy leeks grilled, in pasta dishes or as the key ingredient in vichyssoise — a French-style potato soup. Leeks are a natural source of inulin, which supports good gut bacteria. Leeks provide vitamins A and C, folate and manganese.
A staple in the U.S., onions are an aromatics superstar. High concentrations of allyl sulfides in onions do double duty fighting heart disease and cancer.
