Spaghetti Pizza: The Ultimate Comfort Food Mash-Up
If your family is anything like mine, spaghetti night is always a hit. But sometimes, mixing things up and surprising everyone with a new twist on a classic is fun. That’s where this Spaghetti Pizza recipe comes in. It’s like your favorite pizza toppings met a cheesy spaghetti casserole and made magic. If you’ve never tried New York-style spaghetti pizza or a baked spaghetti pie, you’re in for something seriously satisfying.
What Is Spaghetti Pizza?
Spaghetti Pizza is exactly what it sounds like—your favorite pizza toppings layered over a crust made from spaghetti noodles. The spaghetti acts as the base (kind of like a pizza crust), which gets firm and golden brown when baked. Then it’s topped with cheese and pepperoni, just like a traditional pizza, but with all the cozy comfort of a baked pasta dish.
It’s great for using up leftover pasta, too. The spaghetti mixture forms a cheesy, savory base that holds together beautifully.

Spaghetti Pizza Ingredients
Here’s what you need to make this family-style comfort food:
- 8 ounces spaghetti noodles
- 1 pound Italian sausage (bulk or casings removed)
- 1 teaspoon Italian seasoning
- 1 teaspoon garlic powder (or garlic salt)
- 1 teaspoon coarse kosher salt, plus more for pasta water
- 1/2 teaspoon black pepper
- 2 cups spaghetti sauce (or your favorite marinara or pizza sauce)
- 2 cups shredded mozzarella cheese
- 8-10 slices pepperoni (or your favorite pizza toppings)
- 2 tablespoons fresh parsley, chopped (optional for garnish)
Optional add-ins: red pepper flakes, diced tomatoes, fresh basil, sliced red onions, mushrooms, or olives.
How to Make Spaghetti Pizza
Step 1: Preheat the Oven
Preheat your oven to 375°F. Spray your baking dish with cooking spray or brush with olive oil to prevent sticking.
Step 2: Cook the Spaghetti
Bring a large pot of salted water to a boil. Cook the spaghetti until al dente, drain, and set aside to cool slightly to room temperature.
Step 3: Cook the Sausage
In a skillet over medium heat, cook the Italian sausage until browned. Stir in the Italian seasoning, garlic powder, salt, and black pepper. Let cook for 1-2 more minutes until fragrant.
Step 4: Combine in a Large Bowl
In a large bowl, mix the cooked pasta, sausage, and spaghetti sauce until everything is evenly coated. This will be your base spaghetti mixture.
Step 5: Assemble the Pizza
Spread the pasta mixture into a greased baking dish (about 9×13). Top with the mozzarella cheese layer and arrange pepperoni slices or other toppings.
Step 6: Bake
Bake uncovered for 20-25 minutes or until the cheese is melted and bubbly and the edges are crisp and golden brown.
Step 7: Garnish and Serve
Let the spaghetti pizza cool slightly before slicing. Garnish with fresh parsley or fresh basil, and serve hot.
