Ingredients:
- 2 tablespoons olive oil
- 1 large onion, finely chopped
- 2 carrots, finely chopped
- 2 celery stalks, finely chopped
- 4 cloves garlic, minced
- 1 teaspoon dried oregano
- 1/2 teaspoon dried basil
- 1/4 teaspoon red pepper flakes (optional)
- 2 (28 ounce) cans crushed tomatoes
- 1 (15 ounce) can tomato sauce
- 2 tablespoons tomato paste
- 1 cup dry red wine (optional)
- 1/2 cup beef broth
- 1 bay leaf
- 1 teaspoon granulated sugar
- Salt and freshly ground black pepper to taste
Instructions:
- Heat olive oil in a large pot over medium heat. Add onion, carrots, and celery and sauté until softened, about 8-10 minutes. Add garlic, oregano, basil, and red pepper flakes (if using) and cook for another minute until fragrant.
- Stir in crushed tomatoes, tomato sauce, and tomato paste. Mix well to combine.
- If using, pour in the red wine and scrape up any browned bits from the bottom of the pot. Add beef broth, bay leaf, sugar, salt, and pepper. Bring to a simmer, then reduce heat to low, cover, and cook for at least 2 hours, or up to 3 hours, stirring occasionally to prevent sticking.
- Remove the bay leaf. Taste and adjust seasoning as needed. If the sauce is too thick, add a little more broth. If it's too thin, simmer uncovered for a bit longer. Let cool slightly before using in your lasagne.
