Ingredients Overview

This stew relies on whole-food, pantry-friendly ingredients that work together to create a flavorful, well-balanced dish. Let’s look at what each brings to the table.

Lentils (Brown or Green)

Lentils form the protein base of this stew. Brown and green lentils are ideal because they hold their shape through cooking, giving a firm texture and hearty bite. They also absorb flavors well and make the dish feel satisfying and complete.

Alternative: For a slightly firmer texture and more robust flavor, consider using French green (Puy) lentils.

Mushrooms

Mushrooms provide an umami-rich base that mimics the depth of flavor you’d typically find in a beef stew. Cremini (baby bella) mushrooms work particularly well, offering chew and richness when browned properly.

Tip: Sauté mushrooms separately if needed to ensure they develop a golden crust — this step is essential for unlocking their full flavor.

Optional: Add a variety like portobello or shiitake for added complexity.

Onion, Garlic, Carrot & Celery

The classic mirepoix (onion, carrot, celery) forms the stew’s foundational flavor. Cooked slowly, these vegetables release their natural sweetness and aroma.

• Onion gives a mild, sweet base.

• Carrot and celery add texture and balance.

• Garlic deepens the flavor profile with its aromatic punch.

Tomato Paste

Just a small spoonful of tomato paste brings richness and subtle acidity. Sautéing it for a minute or two before adding broth intensifies its savory notes.

Vegetable Broth

A high-quality vegetable broth is key to achieving a stew with depth. Use low-sodium varieties so you can adjust salt to taste.

Flavor Tip: Add a touch of soy sauce, miso, or tamari to enhance the savory character of the broth.

Potatoes

Diced Yukon Gold or red potatoes offer creamy texture and absorb the stew’s bold flavors while adding natural thickness as they break down.

Variation: Swap in sweet potatoes for a sweeter, more vibrant flavor.

Seasonings and Herbs

Aromatic herbs like rosemary and thyme bring an earthy, homey feel to the stew. Bay leaves provide subtle complexity, while smoked paprika adds a faint smokiness that ties everything together.

Finish with freshly ground black pepper and salt to round out the flavors.

Step-by-Step Instructions

This stew builds flavor in layers, starting with deeply browned vegetables and ending in a simmered, satisfying bowl of comfort. Here’s how to make it from start to finish:

1. Cook the Base Vegetables

Start by heating oil in a large pot or Dutch oven over medium heat. Add the diced onions, carrots, and celery. Sauté them for about 8 minutes, stirring occasionally, until they soften and the onions become slightly translucent.

Stir in minced garlic and cook for another 30–60 seconds, just until fragrant.

2. Sauté the Mushrooms

Add the sliced mushrooms to the pot. Sprinkle with a little salt and cook uncovered, letting them brown on one side before stirring. This process can take 8–10 minutes. You’re looking for deep color and reduced moisture — a key step for unlocking their rich, meaty flavor.

3. Add Tomato Paste and Seasonings

Once the mushrooms are nicely browned, stir in the tomato paste. Let it toast in the pot for 1–2 minutes until slightly darkened. Then add thyme, rosemary, smoked paprika, and bay leaves. Stir everything well to coat the veggies evenly.

4. Add Lentils and Liquid

Deglaze the pot with a splash of broth, scraping up any browned bits on the bottom. This adds flavor back into the dish.

Add the lentils and diced potatoes, followed by the remaining broth. Stir to combine all ingredients.

5. Simmer to Perfection

Bring the stew to a gentle boil, then reduce the heat and let it simmer covered for about 30–35 minutes. Stir occasionally to prevent sticking, and add more broth or water if the mixture gets too thick.

Cook until the lentils and potatoes are tender and the stew has thickened slightly.

6. Final Adjustments

Taste the stew and season with salt and black pepper as needed. A splash of lemon juice or balsamic vinegar at the end adds a bright note that balances the savory base.

Remove the bay leaves before serving.
