Heat a large skillet over medium-high heat. Coat pan with cooking spray. Add sausage, beef, and garlic; cook 4 minutes or until meat is browned, stirring frequently to crumble. Stir in marinara sauce, salt, and pepper; bring just to a simmer. Remove from heat. Stir in frozen ravioli; toss to combine.
Coat an 8-inch square broiler-safe glass or ceramic baking dish with cooking spray. Spoon ravioli mixture into pan; top evenly with mozzarella cheese. Cover dish tightly with foil coated with cooking spray. Bake at 375° for 40 minutes. Uncover and sprinkle evenly with Parmigiano-Reggiano cheese.
Preheat broiler (leave dish in oven). Broil 3 minutes or until cheese is bubbly and lightly browned.
This was so easy to prepare and you got the same satisfaction as lasagna. I could not find spinach ravioli so I sautéed garlic in olive oil and wilted a bag of spinach in a pan. I chopped it and added it to the baking dish along with the ravioli mixture. If you use a normal size ravioli the serving size is correct. This would be a great recipe to double and bring to a party.
My husband and I thought this dish was pretty darn good for the effort involved, and it tasted healthier than our usual homemade lasagna. We would definitely make it again. The whole wheat spinach ricotta ravioli is not easy to find - I checked Trader Joe's, Ralph's and Target for something similar and didn't find it. So I made a trip to Whole Foods, as the recipe suggested, and found it there. I baked the lasagna in the same oven-proof skillet in which I did the initial preparation, which worked great.
Just made this after receiving this month's edition, so easy and excellent! Substituted hot Italian turkey sausage and don't think it hurt the recipe a bit. My husband is gluten intolerant, so thankfully, frozen gluten free ravioli is available. The crushed red pepper and sausage give this recipe just the right amount of zing!
