Meat Sauce Ingredients
  • 1 pound lean ground beef

  • 1 29 ounce can tomato sauce
  • 1 6 ounce can tomato paste
  • 1.5 teaspoons salt
  • 1 teaspoon dried oregano

Equipment

  • Slow Cooker

Method
 

  1. In a large skillet over medium heat, cook the ground beef and chopped onion until the beef is browned. Drain any excess fat.
  2. Stir in the minced garlic, tomato sauce, tomato paste, salt, and dried oregano. Simmer this meat sauce for about 10 minutes, stirring occasionally.
  3. In a separate bowl, combine the mozzarella cheese, cottage cheese, and Parmesan cheese.
  4. Begin layering the lasagna in your slow cooker. Start with a thin layer of meat sauce on the bottom. Follow this with a layer of lasagna noodles, then a layer of the cheese mixture.
  5. Repeat the layers: meat sauce, noodles, cheese mixture. Continue until you have used all the ingredients, ending with a final layer of meat sauce on top.
  6. Cover the slow cooker and cook on low for 4 hours or on high for 2 hours. The lasagna is done when the noodles are tender.
  7. Let the lasagna rest for about 15 minutes before slicing and serving. This helps the layers set.

Notes

If you are following a keto diet, substitute the traditional lasagna noodles with thinly sliced zucchini or eggplant to keep the meal low-carb.
