Step 1: Preheat oven to 375º F. Spread 1/2 cup of the sauce in bottom of an 11×15 inch baking dish. Bring a large pot of water to boil. Add 1 tsp salt and entire package of lasagna noodles one at a time to pot. Cook according to package instructions. You won’t need all of the noodles, but they sometimes break during cooking, so it’s better to have extra.

Step 2: While noodles are cooking, brown ground beef in a large skillet. Drain fat and discard. Stir in remaining red sauce and heat over low heat. Carefully drain noodles (the water and steam will be very hot!) and rinse with a bit of cold water. This will cool them down and make them easier to work with.

Step 3: Arrange 5 noodles over sauce, slightly overlapping and place one more in the opposite direction at the end, cutting it to fit. Spread a third of the sauce over noodles. Sprinkle 2 cups of mozzarella and 1/3 cup of parmesan cheese over sauce. Arrange 6 more noodles like before (with 1 reserved for the end) and repeat process until all ingredients are used (3 layers).

Step 4: Place foil over top loosely and slightly tented so it doesn’t touch the cheese. Bake at 375º F for 20 minutes. Remove foil using oven mitts (foil and pan will be hot) and bake another 10-20 minutes or until cheese is melted and lightly browned. Let cool for 5-10 minutes before cutting and serving. Enjoy with garlic bread or a side salad!

Tips:

Use your favorite homemade red sauce in place of the jarred sauce.
Replace ground beef with Italian sausage or use both.
Substitute grated parmesan cheese in place of shredded if desired.
Make ahead and store in the refrigerator until ready to bake. Add 20-30 minutes of cook time at 350º F with foil on.
This can be made in a 9×13 inch baking dish by reducing the servings to 8 in the recipe card. Follow the rest of the steps, except for step 3. Four noodles slightly overlapping will fit perfectly in a 9×13 inch dish.
