Ingredients For Lentil Bolognese Sauce
Ingredient Notes
- Fennel Seeds: Fennel seeds are a highly aromatic, flavorful spice commonly used in Mediterranean and Middle Eastern cuisine. They have a sweet licorice-like flavor that can add a unique depth and complexity to various dishes.
- Red Split Lentils: Red split lentils are a type of lentil that have been hulled and split in half, making them cook more quickly when cooked. High in protein, they thicken the sauce and provide a meaty texture.
- Red Wine: Adds depth, acidity, and a hint of richness to the sauce. Using wine is entirely optional in this recipe.
It’s important to note that when making substitutions in recipes, the texture and flavor may be slightly different. However, these substitutes are the best options to change the original recipe.
Ingredient Substitutions
- Olive Oil: This can be substituted with neutral-flavored oil like canola or vegetable oil.
- Onion: Leeks or shallots can be used for a milder flavor profile.
- Garlic: Garlic powder or minced jarred garlic are convenient alternatives.
- Fennel Seeds: Anise seeds or a small pinch of ground star anise can be used for a similar flavor.
- Dried Oregano: Marjoram or dried thyme can be used as a substitute.
- Dried Basil: Fresh basil (added towards the end of cooking) or dried parsley can be used.
- Dried Thyme: Herbes de Provence or Italian seasoning can be a good alternative.
- Crushed Tomatoes: Diced tomatoes or tomato sauce can be used, though the texture will be slightly different.
- Red Lentils: Green or brown lentils can be used, but they take longer and have a firmer texture.
- Red Wine: Sherry or port are good substitutes for red wine. Beef or vegetable broth can be used as a non-alcoholic substitute or try a splash of balsamic vinegar for a touch of acidity.
Recipe Variations
- Bell Peppers: Add diced bell peppers for sweetness and color.
- Carrots and Celery: Add diced carrots and celery with the onions for a classic mirepoix base and added nutrition.
- Creamy: Swirl in 35% heavy cream for a twist on classic rosé sauce. For a vegan option, try coconut milk or cashew cream.
- Herbs: Fresh herbs like rosemary or sage can be added for a different aromatic profile.
- Mushrooms: Add chopped mushrooms for a meatier texture and earthy flavor.
- Pasta Bake: Layer the sauce with pasta and cheese, and bake for a comforting pasta bake dish.
- Spicy: Stir in red pepper flakes or chili powder for a spicy kick.
- Wine Alternatives: Use white wine instead of red for a lighter flavor or apple cider vinegar for a non-alcoholic tang.
- Zucchini: Stir in grated or diced zucchini for extra vegetables and a lighter texture.

How To Make Lentil Bolognese Sauce
STEP 1: Heat the olive oil in a pot. Sautée the onion and garlic until fragrant.
STEP 2: Add the herbs and spices and cook for one minute.
STEP 3: Add the red wine to the pot if using. Cook for one minute, then stir in the crushed tomatoes.

Expert Tips
1. Try toasting the fennel seeds in a dry skillet before adding them to the pot with the onions and garlic.
2. For a thicker, creamier texture, purée half of the sauce in a blender or food processor, then stir it back into the pot.
3. Add a teaspoon or two of sugar to the end of cooking, adjusting to taste as needed.
Recipe Notes
- Don’t skip the fennel seeds if you can help it. They add a distinct flavor, reminiscent of a true Italian ragu, which you simply can’t get with any other herb or spice.
- For a richer sauce, try adding ½ cup (125ml) of 35% whipping cream five minutes before it’s finished cooking.
Storage
- This recipe scales well, making it perfect for meal prepping or freezing. Allow the sauce to cool completely before storing it in airtight containers or freezer bags in the fridge for up to five days or in the freezer for up to two months.
- When reheating the sauce, add a splash of water or vegetable broth to loosen it up and prevent it from sticking to the bottom of the pan. You can also reheat it gently in the microwave.
- To make this recipe gluten-free, use gluten-free pasta or polenta. You can skip the pasta and serve lentil Bolognese sauce over zucchini noodles or spaghetti squash or use it as a filling for stuffed bell peppers.
