Ingredients

• For the ‘Meaty’ Base:

• 1 teaspoon dried thyme
• 1/2 teaspoon red pepper flakes (optional, adjust to taste)
• For the Sauce:
• 1 (6 oz) can tomato paste
• 1 cup dry red wine, such as Chianti or Merlot (see substitutions for non-alcoholic)
• 2 (28 oz) cans crushed tomatoes
• 2 cups high-quality vegetable broth

• 3 tablespoons soy sauce or tamari
• 2 tablespoons nutritional yeast
• 1 tablespoon balsamic vinegar
• 1 cup fresh basil or parsley, chopped
• Salt and freshly ground black pepper to taste

Instructions

1. Step 1: Prepare the Lentils. In a small saucepan, combine the rinsed lentils and 3 cups of water or vegetable broth. Bring to a boil, then reduce heat to a simmer. Cook for 20-25 minutes, or until tender but not mushy. Drain any excess liquid and set aside. (Alternatively, you can use two 15-oz cans of cooked lentils, rinsed and drained).
2. Step 2: Create the Walnut-Mushroom ‘Mince’. While the lentils cook, add the walnuts to the bowl of a food processor. Pulse 5-7 times until they are coarsely ground into a texture resembling coarse breadcrumbs. Be careful not to over-process into a paste. Transfer the ground walnuts to a bowl. Add half of the roughly chopped mushrooms to the now-empty food processor and pulse until finely minced. Transfer to a separate large bowl. Repeat with the remaining mushrooms.
3. Step 3: Brown the ‘Mince’. Heat 1 tablespoon of olive oil in a large skillet or your Dutch oven over medium-high heat. Add the ground walnuts and toast for 2-3 minutes, stirring frequently, until fragrant. Transfer the toasted walnuts back to their bowl. Add the remaining 2 tablespoons of olive oil to the pot. Add the minced mushrooms. Cook, stirring occasionally, for 10-15 minutes. The mushrooms will first release a lot of water; continue cooking until all the water has evaporated and the mushrooms are browned and significantly reduced in volume. This step is crucial for developing a deep, savory flavor.
4. Step 4: Build the Soffritto. Add the toasted walnuts back to the pot with the browned mushrooms. Stir to combine, then transfer the entire mixture to a bowl and set aside. In the same Dutch oven, add the finely diced onion, carrots, and celery (the soffritto). Sauté over medium heat for 8-10 minutes, stirring occasionally, until the vegetables are soft, translucent, and fragrant.
5. Step 5: Add Aromatics and Tomato Paste. Add the minced garlic, dried oregano, dried thyme, and red pepper flakes to the soffritto. Cook for another minute until the garlic is fragrant. Push the vegetables to the side of the pot, creating a space in the center. Add the tomato paste to this space and cook, stirring it constantly, for 2-3 minutes. It will darken in color to a brick red. This caramelization process removes the raw tomato taste and builds a huge layer of umami flavor.
6. Step 6: Deglaze the Pot. Pour in the red wine to deglaze the pot. Use your wooden spoon to scrape up any browned bits (fond) from the bottom. This is pure flavor! Let the wine simmer and reduce by about half, which should take 3-4 minutes.
7. Step 7: Combine and Simmer. Return the mushroom-walnut mixture to the pot along with the cooked lentils. Stir everything together. Add the crushed tomatoes, 2 cups of vegetable broth, and the bay leaves. Stir well to combine.
8. Step 8: The Long Simmer. Bring the sauce to a gentle simmer. Once simmering, reduce the heat to low, cover the pot partially (leaving a small gap for steam to escape), and let it cook for at least 1 hour, stirring every 15-20 minutes to prevent sticking. The longer it simmers, the more the flavors will meld and deepen. The sauce should be thick and rich.
9. Step 9: Final Seasoning. After simmering, remove the bay leaves. Stir in the soy sauce (or tamari), nutritional yeast, and balsamic vinegar. These ingredients will brighten the flavors and add a final layer of savory depth. Taste the sauce and season generously with salt and freshly ground black pepper. Your palate is the final judge, so adjust until the flavors sing.
10. Step 10: Finish and Serve. Stir in the fresh chopped basil or parsley. Serve hot over your favorite pasta, such as pappardelle or tagliatelle, or use in lasagna or over polenta.

Expert Cooking Tips

• Don’t Rush the Browning: The single most important step for flavor development is browning the mushrooms properly. You must cook out all their water until they begin to sizzle and brown. This concentrates their flavor and creates a meaty texture.
• Fine, Even Dice: Take your time dicing the soffritto (onions, carrots, celery). A small, uniform dice allows the vegetables to melt into the sauce, creating a smooth, rich base without large chunks.
• Caramelize the Tomato Paste: Do not skip the step of cooking the tomato paste on its own for a few minutes. This ‘toasting’ process deepens its flavor from simply tomato-y to rich and savory.
• The Low-and-Slow Simmer is Key: While the sauce is delicious after an hour, if you have the time, letting it simmer for 1.5 to 2 hours will result in an even more complex and velvety sauce. Just be sure to stir occasionally and add a splash of broth if it becomes too thick.
• Taste As You Go: Season lightly at the beginning and then do a final, thorough seasoning at the end. The flavors will concentrate as the sauce simmers, so waiting until the end to make major salt adjustments is crucial.

Substitutions and Variations

For a nut-free version, you can substitute the walnuts with 1.5 cups of roasted sunflower seeds (pulsed in the food processor) or simply omit them and increase the mushrooms to 2.5 lbs. For a gluten-free version, ensure you use tamari instead of soy sauce and serve with your favorite gluten-free pasta. If you prefer to cook without alcohol, you can substitute the red wine with an equal amount of vegetable broth plus 1 tablespoon of red wine vinegar or balsamic vinegar to add back some of the acidity.

Common Mistakes to Avoid

The most common mistake is not cooking the mushrooms long enough, resulting in a watery, bland sauce. Be patient and wait for them to brown properly. Another error is over-processing the walnuts and mushrooms into a paste; you want to pulse them to maintain some texture. Skipping the caramelization of the tomato paste will result in a less complex flavor profile. Finally, under-seasoning is a frequent issue. This is a big, rich sauce that requires a good amount of salt and pepper at the end to make all the deep flavors pop.

Serving Suggestions

The classic pairing is with a wide, flat pasta like pappardelle, tagliatelle, or fettuccine, which perfectly catches the thick sauce. It is also exceptional served over creamy polenta, with gnocchi, or used as a filling for vegan lasagna or stuffed shells. For a lower-carb option, serve it over zucchini noodles or spaghetti squash. Garnish generously with fresh parsley or basil, a drizzle of high-quality extra virgin olive oil, and a sprinkle of vegan Parmesan cheese for the perfect finishing touch.

Storage and Reheating Tips

This bolognese tastes even better the next day as the flavors continue to meld. Store leftovers in an airtight container in the refrigerator for up to 5 days. This sauce also freezes beautifully. Allow it to cool completely, then transfer to freezer-safe containers or bags and freeze for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop.

Frequently Asked Questions

Can I use other types of mushrooms?

Absolutely. While cremini mushrooms provide a great ‘meaty’ flavor, you could use a mix of shiitake for more umami, or even white button mushrooms. A mix of different mushrooms would add wonderful complexity.

Is nutritional yeast necessary?

It’s not strictly necessary, but it is highly recommended. Nutritional yeast adds a cheesy, nutty, savory flavor that mimics the role of Parmesan in a traditional bolognese. If you don’t have it, you can omit it, but the final sauce won’t have the same depth.

Can I make this recipe in a slow cooker or Instant Pot?

Yes. For a slow cooker, complete steps 1-6 on the stovetop, then transfer everything to the slow cooker for step 7. Cook on low for 6-8 hours or on high for 3-4 hours. For an Instant Pot, use the ‘Sauté’ function for steps 1-6, then add the remaining ingredients, seal, and cook on high pressure for 20 minutes, followed by a natural release.
