Ingredients
Meat Sauce
- Olive oil spray
- 1 pound 90% lean ground sirloin beef (or bison)
- ½ medium onion, diced
- 3 cloves garlic, minced
- 1 teaspoon kosher salt, divided
- 1 teaspoon Italian seasoning
- 2 28-ounce cans crushed tomatoes
- ¼ cup water
Cheese Mixture
- 3 cups part-skim cottage cheese (or ricotta, or mix of both)
- 2 large eggs, beaten
- ¼ cup Parmesan cheese (or Pecorino Romano), freshly grated
- ½ cup part-skim shredded mozzarella cheese (reserved from 1 ½ cups)
- ¼ cup chopped fresh parsley
Assembly
- 1 ½ cups part-skim shredded mozzarella cheese (divided into ½ cup for cheese mixture and 1 cup for topping)
- 12 regular uncooked lasagna noodles (such as Barilla 11.25 ounces, not no-boil)
Instructions
- Cook the Beef Mixture: Spray a large pot over medium-high heat with olive oil spray. When hot, add the ground beef and ¾ teaspoon kosher salt. Sauté for 3 to 4 minutes until mostly cooked, then add the diced onion and minced garlic. Continue cooking for 2 minutes until soft and fragrant.
- Add Tomatoes and Simmer: Pour in the crushed tomatoes and ¼ cup water, swirling the tomato cans to get all the sauce out. Add to the pot with the meat. Season with Italian seasoning and the remaining ¼ teaspoon salt, then bring the mixture to a boil. Reduce heat to medium-low, cover, and simmer for about 20 minutes. Taste and adjust salt as needed.
- Prepare Cheese Mixture: In a large bowl, combine the cottage cheese (or ricotta), beaten eggs, Parmesan cheese, ½ cup mozzarella, and chopped fresh parsley. Mix well and set aside.
- Layer the Lasagna: Spray the sides of a 6-quart oval slow cooker with olive oil spray. Spread 1 cup of the meat sauce evenly over the bottom. Layer 3 uncooked lasagna noodles on top, breaking to fit as necessary. Add 1 generous cup of meat sauce over the noodles, followed by one-third of the cheese mixture. Repeat this layering process two more times, finishing with the last three noodles on top. Spread the remaining meat sauce over the noodles; there may be a little extra.
- Slow Cook: Cover and cook the lasagna on low for 3½ to 4 hours, or up to 6 hours depending on your slow cooker and noodles. At the 3-hour mark, check the doneness of the noodles by poking the center with a knife—if it slides in easily and noodles feel tender, the lasagna is done; if resistant, continue cooking for another 30 to 60 minutes.
- Add Final Cheese Layer: Once noodles are tender, sprinkle the remaining 1 cup of shredded mozzarella evenly over the top. Cover again and cook for another 5 to 10 minutes until the cheese is melted and bubbly.
- Rest and Serve: Remove the lid and let the lasagna stand for 10 minutes to set. Cut into 8 pieces and garnish with additional chopped parsley if desired. Serve warm.
Notes
- Breaking the noodles to fit the slow cooker is necessary; do not worry about perfect shapes.
- If ricotta cheese is unavailable, part-skim cottage cheese works well for the cheese mixture.
- Cooking times may vary with different slow cooker models—checking doneness at 3 hours is recommended.
- Using 90% lean ground beef ensures less grease but still flavorful meat sauce.
- For a vegetarian version, substitute ground beef with plant-based crumbles and use vegetable broth in the sauce.
