Step 1

Preheat oven to 400 degrees. Heat a large skillet over medium-high heat. Add olive oil. Add ground beef and cook until cooked through about 7-8 minutes. Break up meat with a wooden spoon. Sprinkle with salt, pepper, garlic powder, and red chili flakes.

Step 2

Reduce heat to medium-low and add marinara sauce.

Step 3

Meanwhile, cook cheese ravioli according to package instructions.

Step 4

Spread 1 cup of the meat sauce on the bottom of 9 x 13-inch baking dish (if you want thicker layers, use a smaller pan). Layer half of the ravioli on top. Top with half of the sauce. Sprinkle with half of the mozzarella cheese. Repeat. Finish off with remaining mozzarella cheese.

Step 5

Loosely cover with foil and bake for 25-30 minutes. Remove from foil and let bake for 5 minutes longer or until the cheese is completely melted. Top with fresh basil ribbons or arugula.
