Step-by-Step Instructions
Step 1: Prepare the Vegetables
Dice the onion, mince the garlic, slice the mushrooms, and chop the carrots and celery. Rinsing the lentils removes any debris and ensures even cooking.
Step 2: Sauté the Aromatics
Heat the olive oil in a large, deep pot or Dutch oven over medium heat. Add the diced onion and sauté for 3–4 minutes, stirring occasionally, until translucent and fragrant.
Step 3: Build Flavor with Mushrooms
Add the sliced mushrooms to the pot. Cook for 5–6 minutes, stirring occasionally, until they release moisture and begin to brown. This step is crucial for developing deep, savory flavors.
Step 4: Add Vegetables and Lentils
Toss in the chopped carrots and celery. Cook for 2 minutes, stirring to combine. Stir in the lentils, tomato paste, smoked paprika, dried thyme, and bay leaf. Mix well to coat everything in the spices.
Step 5: Simmer the Stew
Pour in the vegetable broth and water. Bring the mixture to a boil over high heat. Once boiling, reduce the heat to low, cover the pot, and let it simmer for 25–30 minutes. The lentils should be tender and the stew should have thickened slightly.
Step 6: Finish and Season
Remove the bay leaf from the stew. Stir in the soy sauce or tamari for an extra boost of umami. If you prefer a thicker stew, mix the cornstarch with water in a small bowl, then stir it into the stew. Simmer for 2 more minutes. Taste and season with salt and black pepper as needed.
Tips & Tricks
- Choose the right lentils: Green or brown lentils hold their shape well during cooking. Red lentils cook faster but can become mushy, making them better for soups rather than stews.
- Don’t skip browning the mushrooms: This step adds depth and richness to the stew. Be patient and let them cook until golden brown.
- Add greens at the end: Stir in a handful of spinach or kale during the last 5 minutes of cooking for extra nutrients and color.
- Make it thicker or thinner: For a thicker stew, simmer uncovered for the last 10 minutes. For a brothier consistency, add a splash of water or broth.
Storage Instructions
Refrigerator Storage
Let the stew cool completely before transferring it to an airtight container. Store in the refrigerator for up to 5 days. Reheat gently on the stovetop or in the microwave until warmed through.
Freezer Instructions
Portion the stew into freezer-safe containers or resealable bags. Leave some space at the top as the stew will expand when frozen. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
Variations
Mushroom Lover’s Version
Double the mushrooms and add a splash of balsamic vinegar at the end for extra depth. Top with toasted breadcrumbs for crunch.
Spicy Southwest Stew
Add 1 teaspoon of cumin, ½ teaspoon of chili powder, and a diced jalapeño when sautéing the onions. Garnish with fresh cilantro and avocado slices.
Creamy Coconut Stew
Stir in ½ cup of coconut milk at the end of cooking for a creamy, tropical twist. Garnish with lime wedges and cilantro.
Serving Suggestions
- With crusty bread: Serve the stew in bowls with a slice of warm whole-grain bread or a crusty baguette for dipping.
- Over grains: Spoon the stew over quinoa, brown rice, or mashed potatoes for a heartier meal.
- Fresh and light: Pair with a simple side salad of mixed greens, cherry tomatoes, and a lemon vinaigrette to balance the richness.
Frequently Asked Questions
Can I make this recipe ahead of time?
Absolutely! This stew actually tastes better the next day as the flavors meld together. Prepare it up to 3 days ahead and store it in the refrigerator. Reheat gently before serving.
Is this recipe vegan?
Yes, this recipe is completely vegan as written. It contains no animal products and uses soy sauce or tamari for umami flavor instead of meat.
How long does this stew keep in the freezer?
You can freeze this stew for up to 3 months. Make sure to use airtight containers or freezer bags to prevent freezer burn. Thaw overnight in the refrigerator before reheating.
Can I use canned lentils to save time?
While canned lentils are pre-cooked, they tend to be softer and less flavorful. For the best texture and taste, we recommend using dried lentils. If you must use canned, drain and rinse them well before adding to the stew.
What’s the best way to thicken the stew?
The natural starches in the lentils and vegetables will thicken the stew slightly as it simmers. For a thicker consistency, mix 1 tablespoon of cornstarch with 2 tablespoons of water and stir it in during the last few minutes of cooking.
