Step-by-Step Pizza Spaghetti Recipe
1. Prep the Spaghetti
Preheat your oven to 350°F (180°C). In a large pot of well-salted, boiling water, cook the spaghetti until very al dente—about 8 minutes. Drain and return the noodles to the pot to keep warm.
2. Mix the Filling
Add the pizza sauce, chopped green bell pepper, mini pepperoni, Italian seasoning, half of the mozzarella (1 cup), and half of the Parmesan (1/2 cup) to the pot with your cooked spaghetti. Season generously with salt and freshly ground black pepper. Toss thoroughly so every noodle is coated in sauce and toppings.
3. Layer in the Casserole Dish
Grease a large baking dish (a 9×13-inch pan works well). Spread the spaghetti mixture evenly into the dish, pressing down lightly to form a compact layer.
4. Add the Cheesy Toppings
- Sprinkle the remaining mozzarella and Parmesan over the spaghetti, making sure to cover the entire surface.
- Scatter extra mini pepperoni on top for a decorative, flavorful finish (add other toppings here if desired).
5. Bake to Perfection
Bake the casserole for about 30 minutes, or until the cheese is melted, bubbly, and starting to turn golden on top. If you like a crispier top, broil for the final 2–3 minutes—but watch closely to prevent burning.
6. Garnish and Serve
Remove from the oven and let rest for a few minutes. Sprinkle with freshly chopped parsley for color and a touch of freshness. Slice into squares and serve hot.
Tips for Success and Customization
- Use What You Have: This recipe is flexible—swap in any pizza toppings or cheeses you love.
- Homemade vs. Store-bought Sauce: Both work well, but homemade sauce can impart extra depth of flavor.
- Al Dente Pasta: Slightly undercooking the noodles prevents mushiness after baking.
- Double the Recipe: Feeding a crowd? Simply double all ingredients and bake in two pans.
- Kid-Friendly: Let kids sprinkle on their favorite toppings before baking.
- Make it Vegetarian: Leave out the pepperoni and load up on vegetables.
- Make it Vegan: Use plant-based cheeses and vegan pepperoni, and check your pizza sauce for animal-derived ingredients.
