Ingredients

Gather the following ingredients to prepare your slow baked lasagna casserole:

Ingredients

  • 9 lasagna noodles
  • 1 pound ground beef
  • 1 pound Italian sausage
  • 1 onion, chopped
  • 2 cloves garlic, minced
  • 2 cups marinara sauce
  • 1 can (15 oz) ricotta cheese
  • 2 cups shredded mozzarella cheese
  • 1 cup grated Parmesan cheese
  • 1 egg
  • 2 teaspoons dried Italian herbs
  • Salt and pepper to taste

Ensure all ingredients are prepped and ready for assembly.

Instructions

Follow these steps to create your lasagna casserole:

Cook the Meat

In a large skillet over medium heat, add the ground beef, Italian sausage, onion, and garlic. Cook until the meat is browned and the onions are translucent. Drain excess fat and stir in marinara sauce. Simmer for 10 minutes.

Prepare the Cheese Mixture

In a bowl, combine ricotta cheese, egg, Italian herbs, salt, and pepper. Mix well until smooth.

Assemble the Casserole

Preheat the oven to 375°F (190°C). Spread a thin layer of meat sauce on the bottom of a 9x13 inch baking dish. Layer 3 lasagna noodles, half of the ricotta mixture, and a third of the mozzarella cheese.

Repeat the layers, finishing with meat sauce and the remaining mozzarella and Parmesan cheese on top.

Bake the Casserole

Cover the dish with aluminum foil and bake for 45 minutes. Remove the foil and bake for an additional 15 minutes until the cheese is bubbly and golden. Let it cool for 10 minutes before serving.

Your delicious slow baked lasagna casserole is now ready to serve!

Pro Tips

  • For added flavor, consider using fresh basil or spinach in the layers. You can also substitute ground turkey for a lighter option.

Serving Suggestions

Pair your slow baked lasagna casserole with a fresh green salad and garlic bread for a complete meal that will satisfy any appetite. The crispness of the salad offers a delightful contrast to the rich, cheesy layers of the lasagna. Additionally, a light vinaigrette can help balance the heaviness of the dish, ensuring a well-rounded dining experience.

For a more festive occasion, consider serving it alongside a glass of red wine, such as Chianti or Merlot. The robust flavors of the wine complement the savory meat sauce beautifully, enhancing the overall flavor profile of your meal.

Storage and Reheating

If you have leftovers (though they are often hard to come by!), storing your slow baked lasagna casserole is simple. Allow it to cool completely before covering it tightly with plastic wrap or aluminum foil. It can be stored in the refrigerator for up to three days, or frozen for up to three months. Just remember to label your containers with the date to keep track of freshness.

To reheat, simply thaw if frozen, then place in a preheated oven at 350°F (175°C) until heated through. You can also microwave individual portions for a quick meal. Just cover with a damp paper towel to prevent drying out. Enjoying the leftovers will remind you of the delicious meal you had, making it a wonderful option for busy days.
