No, I did not invent the recipe for Ravioli Lasagna but I did tweak it some to enhance the recipe by adding my personal touch.
First let me say that when you search "ravioli lasagna" you'll only get about 590,000 results!! Most of the recipes call for frozen cheese raviolis, ground beef, jar of spaghetti sauce, and shredded mozzarella cheese. My tweak was to see if I could make it more like a traditional lasagna. It was fun, easy, and SWMBO said it tasted like my lasagna ... mission accomplished! Served with a side of salad and toasted roasted garlic bread ... Bon Appétit
Started by making a quick pork sausage lasagna sauce: 1 lb Jimmy Dean pork sausage, onion, mushrooms, 15 oz tomato sauce, 14.5 oz stewed tomatoes, 6 oz tomato paste, garlic, garlic salt, seasoned salt, black pepper, and Italian seasoning. Simmered sauce for 45 minutes.
Sprayed 9"x11" foil pan with cooking spray and built up ravioli lasagna layers: Layered ⅓ of the sauce, 20 frozen cheese raviolis, mozzarella cheese, and a dab of ricotta cheese on each ravioli. Repeated a second layer of the ingredients. Topped the casserole with the remaining sauce and mozzarella.
Covered the ravioli lasagna tightly with foil and baked in a preheated 400ºF oven for 1 hours. Removed the foil and baked an additional 10 minutes till cheese bubbly and golden brown.
