In a large skillet over medium high heat, cook the ground beef, Italian sausage and onions until no pink is visible. Drain off excess grease and season with onion powder, garlic powder, Italian seasoning, and salt & black pepper.
Add the meat, broth, and marinara sauce to the crockpot. Cook on low for 6-8 hours or high for 3-4 hours.
Once finished cooking, add the broken lasagna sheets to the crockpot. Stir together and allow the lasagna sheets to cook for 30-45 minutes or until al dente.
In the last five minutes add in the ricotta cheese and sprinkle the mozzarella cheese on top of each serving. Serve & enjoy!
