ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

For the lentil stew:

• Brown or green lentils, rinsed

• Onion, diced

• Carrots, diced

• Celery, diced

• Garlic, minced

• Tomato paste

• Vegetable broth or water

• Olive oil

• Thyme and rosemary (dried or fresh)

• Bay leaf

• Salt and pepper

• Optional: red wine or balsamic vinegar for depth

For the mashed potatoes:

• Russet or Yukon gold potatoes, peeled and cubed

• Butter or plant-based butter

• Milk or plant-based milk

• Salt

• Optional: garlic powder or cream cheese for added richness

directions

1. I start by heating olive oil in a large pot over medium heat and sautéing the onion, carrots, and celery until softened.

2. I add the garlic and tomato paste, stirring until fragrant and slightly caramelized.

3. I pour in the lentils, broth, thyme, rosemary, bay leaf, and a pinch of salt and pepper.

4. I bring everything to a boil, then reduce the heat and simmer for 30–35 minutes, or until the lentils are tender and the stew has thickened.

5. Toward the end, I stir in a splash of red wine or balsamic vinegar to deepen the flavor.

6. While the stew simmers, I boil the potatoes in salted water until fork-tender, then drain and mash them with butter and milk until creamy.

7. I season the potatoes to taste and keep them warm.

8. I remove the bay leaf from the stew, taste for seasoning, and serve the lentils spooned generously over a bed of mashed potatoes.

Servings and timing

Prep time: 15 minutes
Cook time: 35–40 minutes
Total time: 50–55 minutes

Variations

Sometimes I add mushrooms to the stew for a meatier texture, or stir in spinach or kale toward the end for extra greens. I’ve also used sweet potatoes for the mash when I want a slightly sweeter, richer base. For a creamier stew, I blend a small portion and stir it back in. And if I’m in the mood for heat, I add a pinch of smoked paprika or chili flakes.

storage/reheating

I store the stew and mashed potatoes separately in airtight containers in the fridge for up to 4 days. When reheating, I warm the stew over low heat on the stove, adding a splash of water or broth if it thickened too much. The mashed potatoes reheat well in the microwave or on the stove with a bit of milk stirred in to bring them back to life.

FAQs

Can I use canned lentils?

Yes, I can use canned lentils for a faster version. I just reduce the cooking time and simmer the stew until the flavors meld, about 15 minutes.

What kind of potatoes work best?

I prefer Russet potatoes for fluffiness or Yukon gold for a buttery, creamy texture.

Can I make this recipe vegan?

Absolutely. I use plant-based butter and milk for the mashed potatoes and vegetable broth for the stew.

Is this dish freezer-friendly?

The lentil stew freezes very well. The mashed potatoes can be frozen, but I prefer them fresh or refrigerated for best texture.

Can I add protein to make it even heartier?

Sure, I can stir in cooked sausage, shredded chicken, or even a fried egg on top if I want a protein boost.
