Steps

Before you start

Rinse the brown lentils under cold water and pick through them for any pebbles or debris
Have your vegetable broth ready (can be warm or cold)
Chop all vegetables before you start cooking

1
Sauté aromatics
- Heat 1½ tablespoons (22 ml) olive oil in a 3-quart (2.8 L) pot over medium-high heat for 1 minute until shimmering.
- Add the diced onion and cook for 2–3 minutes, stirring occasionally, until softened and fragrant.
- Add the minced garlic and cook for 30 seconds until aromatic.

Ready when: Onion is translucent and fragrant; garlic releases its aroma
Tip: Don't let the garlic brown or it will taste bitter.
2
Add celery and carrot
- Stir in the diced celery and carrot.
- Cook for 2 minutes, stirring frequently, to soften the vegetables slightly and release their flavors into the oil.

Ready when: Vegetables are slightly softer and fragrant
3
Add lentils and seasonings
- Pour in the rinsed brown lentils and stir to coat with oil.
- Add the vegetable broth, dried thyme, and bay leaf.
- Stir well to combine.
- Bring the mixture to a boil over medium-high heat, which takes about 3–4 minutes.

Ready when: Mixture reaches a rolling boil with visible bubbles
Tip: Use the exact amount of broth—too much will make the lentils mushy, too little and they won't cook through.
4
Simmer covered
- Once boiling, reduce the heat to medium-low and partially cover the pot with a lid, leaving it slightly ajar.
- Simmer for 25–28 minutes, stirring occasionally (every 7–8 minutes), until the brown lentils are tender but still hold their shape.
- The broth should be mostly absorbed at the end.
+ Show details− Hide details
Ready when: Lentils are fork-tender but not mushy; broth is nearly absorbed and lentils sit in about ¼ inch of liquid
Tip: Stir occasionally to prevent the bottom from sticking and to ensure even cooking. The lentils should be creamy inside but intact, not falling apart.
5
Season and rest
- Remove the pot from heat and discard the bay leaf.
- Taste the dish and season with kosher salt and freshly ground black pepper to your preference.
- Let it rest uncovered for 1–2 minutes so any excess moisture can evaporate and flavors can settle.
+ Show details− Hide details
Ready when: Bay leaf is removed; lentils taste well-seasoned
Tip: Season at the end rather than early in cooking so you don't end up over-salting as the liquid reduces.
6
Serve
- Spoon the lentil mixture into bowls or onto plates.
- Serve warm as a side dish alongside roasted proteins, over grains, or as a base for a vegetable bowl.

Tip: If the lentils have cooled, reheat gently over low heat with a splash of broth to restore creaminess.

Tips

Brown lentils hold their shape better than red or yellow lentils, making them ideal for this one-pot side. They have a mild, slightly earthy flavor that pairs well with almost any protein.
For a heartier dish, stir in 2 tablespoons (8 g) of fresh parsley or a squeeze of lemon juice at the end, or serve over grains like quinoa or rice.
If your lentils finish cooking but the broth is still watery, uncover the pot and simmer for another 3–5 minutes to evaporate the excess liquid.
This dish tastes even better the next day as the flavors deepen and meld. Make it ahead for weeknight dinners.

Make ahead

Lentils can be cooked 1–2 days ahead and stored in an airtight container in the refrigerator. Reheat gently on the stovetop over low heat, stirring often and adding a splash of broth or water if the mixture is too thick.

Storage & reheating

Room temperature (not recommended; best refrigerated): up to 2 hours. Refrigerator: up to 3 days in an airtight container. Freezer: up to 2 months in a freezer-safe container or bag. Thaw overnight in the refrigerator and reheat on the stovetop or in the microwave with a splash of broth.

Substitutions

vegetable broth → Chicken or beef broth, or water with a bouillon cube. Chicken broth adds richness; water will produce a lighter, less savory dish.
dried thyme → 1 teaspoon fresh thyme leaves, or ½ teaspoon dried oregano or Italian seasoning. Fresh thyme is more delicate; add it in the last 2 minutes of cooking. Oregano will give an earthier flavor.
brown lentils → Green (French) lentils or red lentils. Green lentils will hold their shape similarly. Red lentils cook faster (15–18 minutes) and will become softer and more creamy.
bay leaf → Omit, or use a sprig of fresh parsley or a whole garlic clove. Bay leaf adds subtle depth; the dish is fine without it. Fresh parsley adds brightness instead.
