Ingredients
Vegetables & Aromatics
- 1 small yellow onion, finely diced
- 1 small carrot, finely diced
- 1 celery rib, finely diced
- 8 oz baby bella mushrooms, finely diced (can use cremini or white mushrooms)
- 3 cloves garlic, minced
Main Ingredients
- 2 tablespoons olive oil
- 15 oz can lentils, rinsed and drained
- 1 tablespoon balsamic vinegar
- 1 teaspoon Italian seasoning
- 1/4 teaspoon crushed red pepper flakes
- 24 oz marinara sauce
Seasonings & Garnishes
- Kosher salt and black pepper, to taste
- Freshly grated Parmesan cheese, optional for garnish
- Fresh basil, optional for garnish
- For serving: pasta or spaghetti squash
Instructions
- Sauté Vegetables: In a large skillet, heat the olive oil over medium-high heat. Add the finely diced onion, carrot, celery, and mushrooms. Sauté for 5 to 7 minutes, stirring occasionally, until the vegetables are tender and fragrant.
- Add Garlic and Season: Stir in the minced garlic and cook for 1 minute until aromatic. Season the mixture with kosher salt and freshly ground black pepper to taste.
- Add Lentils and Seasonings: Add the rinsed and drained lentils to the skillet along with balsamic vinegar, Italian seasoning, and crushed red pepper flakes. Stir well and cook for 1 minute to meld the flavors.
- Simmer with Marinara Sauce: Pour in the marinara sauce and reduce the heat to low. Let the sauce simmer gently for 10 minutes, allowing the flavors to combine and the sauce to thicken slightly.
- Adjust Seasoning and Serve: Taste the sauce and adjust salt and pepper as needed. Serve hot over your choice of pasta or spaghetti squash. For extra flavor, garnish with freshly grated Parmesan cheese and fresh basil. This sauce also pairs well spooned over polenta, baked sweet potatoes, or even eggs.
Notes
- Storage: Store leftovers in an airtight container in the refrigerator for up to 5 days.
- Freezing: Freeze in portions for up to 3 months. Ensure the sauce cools completely before freezing for best quality.
- Reheating: Reheat gently on the stovetop or in the microwave until warmed through. Add a splash of water or broth if the sauce becomes too thick during reheating.
