Ingredients:
- 2 lbs lean ground beef (90/10)
- 1 large onion, grated
- 2 medium carrots, grated
- 2 celery stalks, grated
- 4 cloves garlic, minced
- 28 oz crushed tomatoes
- 6 oz tomato paste
- 0.5 cup dry red wine
- 1 tbsp dried oregano
- 0.5 tsp red pepper flakes
- 15 oz part-skim ricotta cheese, strained
- 1 large egg
- 0.5 cup freshly grated Parmigiano-Reggiano
- 0.25 cup fresh parsley, finely chopped
- 1 cup fresh baby spinach, finely chopped
- 12 lasagna sheets
- 3 cups low-moisture part-skim mozzarella cheese, shredded
Instructions:
- In a large heavy-bottomed skillet or Dutch oven, brown the lean ground beef over medium-high heat. Drain any excess rendered fat to ensure a clean flavor profile.
- Add the grated onion, grated carrots, and grated celery to the beef. Sauté for 6-8 minutes until the vegetables are softened and slightly caramelized.
- Stir in the minced garlic, tomato paste, oregano, and red pepper flakes. Cook for 2 minutes until the tomato paste turns a deep rust color.
- Deglaze the pan with the dry red wine, scraping the bottom to release the browned bits (fond). Simmer until the liquid has reduced by half.
- Pour in the crushed tomatoes. Reduce heat to low and simmer for 30-45 minutes until the sauce is thick and velvety.
- In a medium bowl, combine the strained ricotta, egg, grated Parmesan, chopped parsley, and chopped spinach. Mix until well incorporated.
- Preheat oven to 375°F (190°C). In a 9x13 inch baking dish, spread 1 cup of meat sauce on the bottom. Layer with lasagna noodles, followed by a layer of the ricotta mixture, more meat sauce, and mozzarella cheese.
- Repeat the layers, finishing with a generous coating of mozzarella and Parmesan. Cover with foil and bake for 25 minutes.
- Remove foil and bake for an additional 20-25 minutes until the cheese is golden and bubbling. Let rest for 15 minutes before slicing to ensure structural integrity.
