Lazy-Day Lasagna

Step 1 -Preheat the oven to 350 degrees F.

Step 2 -In a medium skillet, cook the ground beef, while crumbling, over medium heat until completely browned, about 5-7 minutes. Drain the excess fat from the skillet.

Step 3 -Add all but 3/4 cup of the spaghetti sauce to the skillet with the ground beef and stir well.

Step 4 -Cover and simmer the meat sauce mixture, stirring occasionally, over medium-low until thickened, about 10 minutes.

Step 5 -Spread 1/4 cup of the reserved spaghetti sauce into the bottom of a 9x13-inch glass baking dish.

Step 6 -Arrange 1/3 of the frozen ravioli in a single layer in the pan.

Step 7 -Top the ravioli with 1/2 of the meat sauce and 1/3 of the mozzarella, in that order.

Step 8 -Repeat the layers.

Step 9 -Layer the lasagna with the remaining ravioli, the remaining reserved spaghetti sauce, and the remaining mozzarella cheese, in that order.

Step 10 -Bake until the cheese is completely melted and the lasagna is bubbling around the edges, about 30-40 minutes.

Step 11 -Serve.
