Step 1

Heat a large skillet over medium-high heat. Add ground beef and cook until brown and crumbly, 5 to 8 minutes. Drain grease from skillet.

Step 2

Pour in 1/2 of the pasta sauce and mix with browned ground beef. Break up lasagna noodles into 4 or 5 pieces each and set on top of the ground beef-sauce mixture. Add the remaining pasta sauce on top of the noodles and stir. Cover and simmer over medium-low heat until noodles are soft, about 25 minutes.

Step 3

Add ricotta cheese to the skillet and stir until melted. Sprinkle mozzarella cheese and Parmesan cheese on top; cover and let sit until cheese has melted, about 5 minutes.
