Ingredients:
- 1 lb ground beef (80/20 blend)
- 1 small yellow onion, finely diced
- 3 cloves garlic, minced
- 28 oz high-quality marinara sauce
- 2 tbsp tomato paste
- 1 tsp dried oregano
- 1/2 tsp crushed red pepper flakes
- 15 oz whole milk ricotta cheese
- 1 large egg, lightly beaten
- 1/2 cup freshly grated Parmesan cheese
- 11 regular lasagna noodles, dry
- 3 cups low-moisture mozzarella cheese, shredded
- Fresh parsley and basil
Instructions:
- Place your ground beef in a large skillet over medium high heat. Cook until deeply browned and a sizzle is constant, breaking it up with a spatula.
- Add the diced onion to the beef. Note: The fat from the beef helps soften the onions without adding extra oil.
- Stir in the minced garlic and tomato paste. Cook for 2 minutes until the paste turns a dark brick red.
- Pour in the marinara sauce, oregano, and red pepper flakes. Let it bubble for 5 minutes, then remove from heat.
- In a separate bowl, combine the ricotta, egg, Parmesan, parsley, and salt. Whisk until velvety and completely uniform.
- Spread 1 cup of the meat sauce onto the bottom of the slow cooker. Note: This prevents the bottom noodles from sticking and burning.
- Break the dry noodles to fit the shape of your crock. Place 3-4 noodles over the sauce (some overlapping is fine).
- Spread 1/3 of the ricotta mixture over the noodles, followed by a layer of mozzarella and more meat sauce. Repeat this twice.
- End with a layer of noodles, the remaining meat sauce, and a generous topping of mozzarella.
- Cover and cook on LOW for 4 hours until the noodles are tender and the cheese is bubbling.
