How I Make Spaghetti Pizza Bake
Here’s how to build this casserole layer by layer:
Step 1: Prep your dish and cook the pasta
Preheat your oven to 350°F and lightly grease a 3-quart casserole dish. Boil a large pot of salted water, cook the spaghetti according to the package directions, then drain it well and place it in your prepared dish.
Step 2: Brown the sausage
Heat a tablespoon of olive oil in a large skillet over medium-high heat. Add the ground Italian sausage and cook, stirring often, until it’s browned and cooked through, about 5 to 7 minutes. Spread it over the spaghetti in your casserole.
Step 3: Cook the mushrooms
In the same skillet, add the sliced mushrooms and cook them until they’re golden brown and any liquid has evaporated, around 5 minutes. This concentrates their flavor and keeps the casserole from getting watery.
Step 4: Layer the sauce and toppings
Pour the pasta sauce over the spaghetti and sausage, then scatter the cooked mushrooms on top. Sprinkle the Italian cheese blend and parmesan generously, then arrange the pepperoni slices over everything.
Step 5: Bake until bubbly
Bake for 15 to 20 minutes, until the cheese is melted, bubbly, and starting to brown slightly at the edges. You’ll know it’s ready when it looks golden and irresistible.
Recipe FAQs
Can I make this ahead of time?
Yes, you can assemble it completely, cover it, and refrigerate for up to 8 hours before baking. Just add 5 to 10 extra minutes to the baking time if it goes straight from the fridge into the oven.
What if I don't have a 3-quart casserole dish?
A 9×13-inch baking dish works perfectly and will give you about the same depth. Just keep an eye on it so the cheese doesn’t brown too quickly.
Can I double this recipe?
Absolutely. Double all the ingredients and use a larger baking dish or two standard casserole dishes. You may need to add 5 to 10 minutes to the baking time.
Is this recipe freezer-friendly?
Yes, it freezes beautifully for up to 2 months. Cool it completely first, wrap it well, and thaw overnight in the fridge before reheating.
Tips for the Best Results
- Don’t skip browning the mushrooms separately, it removes excess moisture and prevents a soggy casserole.
- Break the spaghetti into thirds before cooking so it’s easier to layer and eat.
- Use a full-fat Italian cheese blend rather than part-skim for better melting and texture.
- Feel free to add extra pepperoni on top; it won’t hurt, and everyone loves more pizza flavor.
- Let the casserole rest for 5 minutes after baking so the cheese sets slightly and it’s easier to serve.
Easy Swaps
- Swap the Italian sausage for ground turkey or chicken for a leaner option.
- Use marinara sauce or any red pasta sauce you have on hand, they all work beautifully.
- Replace pepperoni with Italian ham, bacon, or even cooked Italian meatballs.
- If you don’t have an Italian cheese blend, use shredded mozzarella and add a little extra parmesan.
