1 large onion, chopped (or 1–2 Tbsp dried minced onion)
1 tsp Italian seasoning
2 Tbsp dried parsley flakes
2 tsp garlic powder
2 Tbsp Worcestershire sauce
6 oz can tomato paste
29 oz tomato sauce
2 Tbsp granulated sugar
1 ¼ cups water
Lasagna Layers:
8 oz uncooked lasagna noodles
4 cups shredded mozzarella cheese
1 ½ cups cottage cheese
½ cup freshly grated Parmesan cheese
Instructions
Make the Meat Sauce: In a large skillet over medium heat, brown the ground beef, sausage, and onion until fully cooked. Add salt, pepper, Italian seasoning, parsley, garlic powder, Worcestershire sauce, tomato paste, tomato sauce, sugar, and water. Stir well and let simmer for 15–20 minutes. (You can prepare the sauce in advance and refrigerate it for later use.)
Layer in the Slow Cooker:
Spread ¼ of the meat sauce over the bottom of your slow cooker.
Add ⅓ of the lasagna noodles (break to fit, if needed).
In a separate bowl, mix the mozzarella, cottage cheese, and Parmesan. Spoon ⅓ of the cheese mixture over the noodles.
Repeat the layers two more times.
Finish with the remaining meat sauce and sprinkle with extra mozzarella, if desired.
Cook: Cover and cook on LOW for 4–5 hours, or until the noodles are tender and the cheese is melted.
Notes & Tips
Make Ahead: The meat sauce can be made up to 3 days ahead and stored in the refrigerator.
Freezing Instructions: Freeze the cooked meat sauce for up to 4 months in a freezer-safe container. Thaw before assembling the lasagna.
