• 1 jar (24 oz) marinara or pizza sauce
• 1 teaspoon Italian seasoning
• 1/2 teaspoon crushed red pepper flakes (optional)
• 2 cups shredded mozzarella cheese
• 1/2 cup grated Parmesan cheese
• 1/2 cup sliced pepperoni
• 1/2 cup sliced black olives
• 1/2 cup chopped green bell pepper
• 1/4 cup chopped fresh basil (optional, for garnish)

Instructions

Step 1: Preheat the Oven

1. Preheat your oven to 350°F (175°C).
2. Lightly grease a 9×13-inch baking dish.

Step 2: Cook the Spaghetti

1. Bring a large pot of salted water to a boil. Add the spaghetti and cook according to the package instructions until al dente. Drain and set aside.

Step 3: Prepare the Meat Sauce

1. In a large skillet over medium heat, add the ground Italian sausage or ground beef. Cook until browned, breaking it apart with a spatula, about 5-6 minutes. Drain any excess fat.
2. Add the chopped onion and minced garlic to the skillet. Cook for 2-3 minutes until the onion is soft and translucent.
3. Stir in the marinara or pizza sauce, Italian seasoning, and crushed red pepper flakes (if using). Let the mixture simmer for 5-6 minutes.

Step 4: Assemble the Casserole

1. In a large mixing bowl, combine the cooked spaghetti with half of the meat sauce. Mix until the spaghetti is evenly coated.
2. Spread the spaghetti mixture evenly in the prepared baking dish.
3. Pour the remaining meat sauce over the spaghetti layer, spreading it out evenly.
4. Sprinkle the shredded mozzarella cheese and grated Parmesan cheese over the top.
5. Add the sliced pepperoni, black olives, and chopped green bell pepper on top of the cheese.

Step 5: Bake

1. Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes.
2. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.
3. Let the casserole cool for 10 minutes before serving.

Step 6: Serve

1. Garnish with chopped fresh basil, if desired.
2. Serve warm and enjoy!

Cooking Tips & Notes

• Meat Choice: You can use ground Italian sausage for more flavor or substitute it with ground beef or ground turkey for a lighter option.
• Pasta Cooking: Make sure to cook the spaghetti al dente, as it will continue cooking in the oven and you don’t want it to become mushy.
• Toppings: Feel free to add any of your favorite pizza toppings, such as mushrooms, cooked bacon, or even pineapple.

Variations

• Vegetarian Option: Omit the meat and add more vegetables like sliced mushrooms, zucchini, and bell peppers for a vegetarian version.
• Extra Cheesy: Add an extra layer of ricotta cheese between the spaghetti and meat sauce for a creamy twist.
• Spicy Version: Use spicy Italian sausage and add extra crushed red pepper flakes to the meat sauce for a kick of heat.
