• Easy 30-Minute Red Lentil Bolognese Sauce

There's a big range of pasta sauces, and I love them all. You can go all meaty with plant-based meat substitutes like seitan, Beyond Beef, and Impossible Meats in a tomato sauce. For example, this one adds roasted red peppers and pesto. Or choose a simple roasted tomato sauce.

Bolognese sauces are well-known but are often confused with the standard everyday hearty meaty sauce. But something makes this sauce different.

🥫 What is a bolognese sauce?

Traditional bolognese is a thick tomato-based ragu credited to Bologna in the Emilia-Romana region. However, some sources claim it may have originated in a small town to the west of Bologna. No one knows for certain, if only because this sauce has been made in this region for centuries.

This sauce is meaty, loaded with chopped tomatoes, typically includes onion, celery, carrot, and broth, and is finished with milk. Some say it's not bolognese without veal. Others use a combination of beef and pork and add red wine to the sauce.

The variations are endless. But I say, it's not a bolognese without milk. It contributes a depth of flavor that separates this sauce from the rest.

📝 Instructions Overview

Detailed instructions for making this one-pan red lentil bolognese are in the recipe card below, but here's an overview!

Step 1

Cook the red lentils. Cook the lentils using this guide: How to Cook Red Lentils -Stovetop and Instant Pot Methods.

Step 2

Chop and sauté the veggies. Dice the onion, celery, and carrots, and mince the garlic. Heat olive oil and add the diced onion, celery, and carrots, and sauté until softened. Add the minced garlic and cook for another minute.

Step 3

Add tomato paste. Form a well in the middle of the skillet and add the tomato paste into the well. Stir the tomato paste in the center for 2 minutes until it's pan-roasted.

Step 4

Add remaining ingredients. Stir in the tomatoes and spices. When the lentils are tender, stir them into the sauce. Simmer for 15 minutes to allow the cooked lentils to absorb the flavors of the sauce.

Step 5

Stir in the milk. Remove the sauce from the heat and completely stir in the milk and correct for any seasoning.

🎯 Why This Recipe Works

• Red lentils soften and break down as they continue to cook, giving the sauce a similar texture.
• Cooking red lentils separately from the sauce speeds up the recipe since beans don't soften well when cooked in an acidic environment, like tomatoes.
• Tomatoes provide umami, and pan-roasting the tomato paste gives it an extra boost.
• Milk deepens the flavors of this sauce.

⏰ Tips to Simplify and Save Time

• The prep goes fast, but you can purchase pre-diced onions, celery, and carrots in many grocery store produce departments.
• Make the entire sauce ahead of time. The flavors only get better overnight.

🧊 Can I make this dish ahead?

The sauce is even better when made ahead, plus it's a great sauce to have on hand for those nights when you don't feel like cooking.

• Store in an airtight container in the refrigerator for 4 - 5 days.
• Freeze in a freezer safe container for 2 - 3 months.

🥬 Make it Vegan

Use coconut milk or oat milk in place of dairy-based whole milk.

I love this sauce with coconut milk. It will add a small coconut flavor, but not very much. When I take this path, I also add ½ - 1 teaspoon of garam masala spice mixture.

If you use oat milk, I recommend Oatly - Full Fat.

💡 Ways to Use Red Lentil Bolognese Sauce

• Put it over noodles, obvi.
• Ladle the bolognese over air fryer spaghetti squash noodles (or cooked any other way).
• Spoon some into a pita pocket.
• Make a sloppy joe-style open-faced sandwich by ladling the sauce over toasted bread smeared with olive oil and garlic.
• Sauté baby spinach (I used a 5-ounce plastic container of pre-washed baby spinach per serving) with a little lemon juice, salt, and pepper. Spread the spinach on a plate, and ladle the lentil bolognese over it (pictured below).
