Recipe Information
Ingredients
- 4 cups Cooked spaghetti
- 2 cups Marinara sauce
- 2 cups Shredded mozzarella cheese
- 0.5 cups Grated Parmesan cheese
- 1 cup Cooked ground beef or Italian sausage (optional)
- 1 cup Ricotta cheese
- 1 large Egg
- 0.5 teaspoons Garlic powder
- 1 teaspoons Dried Italian seasoning
- 0.5 teaspoons Salt
- 0.25 teaspoons Black pepper
- 1 tablespoon Olive oil or cooking spray
Instructions
Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with olive oil or cooking spray and set aside.
In a large mixing bowl, combine the cooked spaghetti with the marinara sauce and mix well to coat all the noodles.
In a separate bowl, mix together the ricotta cheese, grated Parmesan cheese, egg, garlic powder, dried Italian seasoning, salt, and black pepper until smooth.
If using cooked ground beef or Italian sausage, stir it into the spaghetti and sauce mixture for added protein and flavor.
Layer half of the spaghetti mixture into the prepared baking dish, spreading it out evenly.
Spread the ricotta mixture evenly over the spaghetti layer, using a spatula to smooth it out.
Add the remaining spaghetti mixture as a second layer over the ricotta mixture.
Top the casserole with the shredded mozzarella cheese in an even layer.
Cover the baking dish with aluminum foil and bake for 20 minutes. Then, remove the foil and bake for an additional 10 minutes or until the cheese is melted and bubbly.
Remove the casserole from the oven and let it sit for 5-10 minutes to set before serving. Garnish with extra Parmesan or fresh herbs if desired.
