What is vegan bolognese made from?

Hearty and rich in flavor, vegan bolognese is an excellent option if you’re avoiding meat or just want a nutrient-dense sauce to serve with pasta. Lentils and chopped mushrooms provide a rich, meatiness while seasoned tomatoes and spices give the sauce the familiar flavor of traditional bolognese. The red wine adds depth and a hint of sophistication. Simmered in a crockpot, the vegan version becomes a full-bodied bolognese sauce that rivals the original.

Ingredients

• Olive oil – You can use other cooking oils like avocado oil or grapeseed oil as a substitute for olive oil.
• Yellow onion – White onions or shallots can be used instead of yellow onions.
• Carrot – Sweet potatoes or parsnips can be used as alternatives to carrots.
• Celery – Fennel stalks can be a great substitute, but I recommend using one or the other to fill out the sauce. If you don’t like celery, don’t worry; it will pick up the other flavors beautifully.
• Baby bella or cremini mushrooms – Regular white mushrooms or portobello mushrooms can be used as alternatives.
• Salt and freshly cracked black pepper – Use any type of salt and pepper you prefer, such as sea salt and ground white pepper.
• Red pepper flakes – If you prefer less heat, you can use a dash of cayenne pepper or omit it altogether.
• Italian seasoning – Make your own blend using dried oregano, basil, thyme, and rosemary.
• Garlic – Garlic powder or roasted garlic can be used in place of fresh garlic.
• Pinot noir red wine (optional) – If you don’t want to use wine, you can substitute with vegetable broth or water for deglazing the pan.
• Crushed tomatoes – Tomato sauce or marinara sauce can be used as a replacement.
• Fire-roasted diced tomatoes – Regular diced tomatoes can be used if fire-roasted ones are not available.
• Tomato paste – Sun-dried tomato paste can be a flavorful alternative.
• Dried green lentils – The size of green lentils works well, but brown or black lentils can be used instead of green lentils in a pinch.
• Vegetable or chicken broth – Use mushroom broth for a richer flavor or water if you don’t have broth on hand.
• Bay leaves – If you don’t have bay leaves, you can add a small amount of thyme or oregano.

How to Make

STEP ONE: Saute the vegetables. Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Add the diced onions and cook for 5 minutes or until the onions begin to look translucent. Add diced carrots, celery, and mushrooms. Cook for 5-10 minutes, or until the vegetables soften and begin to brown. Season with salt, pepper, red pepper flakes, and Italian seasoning. Stir to combine. Add minced garlic and cook for 1 minute or until fragrant.

STEP TWO: Deglaze the pan. Slowly add red wine stirring to get all the bits at the bottom of the pan mixed in. Let it simmer until the red wine is mostly absorbed. 

STEP THREE: Add the ingredients to the crockpot. Add the vegetable mixture to your slow cooker. Add crushed tomatoes, fire-roasted diced tomatoes, tomato paste, dried green lentils, vegetable broth, and bay leaves to the slow cooker. Stir the ingredients together.

STEP FOUR: Cook. Cook on high for 4 hours or on low for 8 hours. 15 minutes before you’re ready to serve, cook the rigatoni according to the instructions on the box.

STEP FIVE: Serve. Remove the bay leaves. Serve the sauce over pasta with fresh chopped parsley, basil, and crusty bread.

What to Serve Bolognese?

This vegan lentil bolognese sauce is just plain yummy, and can be served with several side dishes to create an entire, well-rounded meal. Try any of these:

Freshly baked garlic bread or crusty bread rolls – so perfect for sopping up all the sauce at the bottom of your bowl!

A crisp and refreshing side salad – with mixed greens, cherry tomatoes, and a tangy vinaigrette, the flavors will work very well together.

Roasted or steamed vegetables – like broccoli, asparagus, or Brussels sprouts, for added nutrients and color.

Tips and Recipe Notes

• This recipe needs time for the flavors to develop, so don’t rush the process. Once it’s in the crockpot, you can let it bubble away, but before that, take your time.
• When sautéing the vegetables, let them soften and brown slightly to develop a depth of flavor.
• Remember to remove the bay leaves before serving, as they’re not meant to be eaten.
• Save some cooking water from the pasta when you drain it. You can use it to thin the sauce if it thickens too much.
