Baked Pizza Spaghetti

Chef’s Secret: Okay, lean in — I discovered this when I had leftover spaghetti and a suspiciously generous bag of pepperoni. Turned out, mixing cooked spaghetti with pizza flavors and then baking it gives you that irresistible combination of stretchy cheese, slightly crisped pepperoni edges, and saucy pasta that clings to every forkful. I call it comfort food with a wink: familiar spaghetti textures, but dressed up in pepperoni, melted mozzarella, and Italian herbs so it behaves like a pizza in pasta clothing. You’ll smell bright tomato sauce and toasty pepperoni within minutes, and the top will bubble and brown like a little victory. Keep your favorite jarred sauce handy — this recipe loves shortcuts and forgiving improvisation.

The texture plays between al dente noodles and oozy cheese, while the pepperoni gives little pops of savory fat and crisp curls. It’s easy enough for a weeknight but impressive enough for casual company. And honestly, it’s so forgiving your oven pretty much smiles at you.

Ingredients

For the Main Dish:

• 12 oz spaghetti (about 3/4 of a 16-oz box)
• 1 tbsp olive oil
• 1 lb ground beef or Italian sausage (optional; use extra veggies for vegetarian)
• 1 medium onion, finely chopped
• 2 cloves garlic, minced
• 24 oz pizza sauce or marinara (one jar)
• 1 cup water or low-sodium broth
• 1 tsp dried oregano
• 1 tsp dried basil
• 1/2 tsp red pepper flakes (optional)
• 2 cups shredded mozzarella (plus extra for topping)
• 1/2 cup grated Parmesan or Pecorino
• 6 oz sliced pepperoni (about 1 cup)
• Salt and black pepper, to taste

For the Sauce / Garnish (if applicable):

• Fresh basil leaves or chopped parsley for garnish
• Red pepper flakes, extra
• Olive oil drizzle (optional)

How I Make It

Step 1:

Bring a large pot of salted water to a boil and cook the spaghetti for about 8–10 minutes until just al dente. Drain and toss with a splash of olive oil so the noodles don’t stick. You want them a touch undercooked since they’ll finish in the oven and soak up sauce.

Step 2:

Preheat the oven to 400°F. In a large skillet over medium-high heat, add 1 tbsp olive oil. Sauté the chopped onion until soft and translucent, about 4 minutes. Add the garlic and cook 30 seconds until fragrant. If you use meat, add the 1 lb ground beef or sausage, break it up, and cook until browned and no longer pink — about 5–7 minutes. Season with salt, pepper, oregano, and basil.

Step 3:

Lower heat and pour in the 24 oz pizza sauce and 1 cup water or broth to loosen it. Stir and let the sauce simmer 3–4 minutes so the flavors marry. Taste and adjust seasoning—this is where the sauce should sing. Fold the drained spaghetti into the skillet so the noodles coat in sauce. Stir in 1 1/2 cups of the shredded mozzarella and 1/2 cup Parmesan until evenly combined.

Step 4:

Transfer everything to a 9×13-inch baking dish. Scatter the remaining mozzarella and the sliced pepperoni over the top. Bake uncovered at 400°F for about 20–25 minutes, until cheese melts, bubbles vigorously, and the edges turn golden and slightly crisp. If you love a bronzed top, switch to broil for 1–2 minutes at the very end — watch it like a hawk to avoid burning.

Step 5:

Remove from the oven and let the dish rest 5 minutes to set (this helps the sauce cling to the pasta). Garnish with torn basil or parsley and a light drizzle of olive oil. Serve hot and listen to that cheese stretch — pure joy.

Pro Tips

• Cook pasta to al dente — it soaks up sauce and won’t go mushy after baking.
• For extra crisp pepperoni, place slices on a baking sheet and broil 1–2 minutes before adding to the top.
• Use a mix of mozzarella and a bit of sharp provolone for deeper flavor. For a lighter dish, swap half the cheese for part-skim mozzarella.
• Make it ahead: assemble, cover, and refrigerate up to 24 hours; add 5–10 minutes to bake time if cold from the fridge.

Common Mistakes to Avoid

• Skipping preheating: Classic rookie move. It changes texture and bake time.
• Overmixing: Leads to dense or chewy results. Mix until just combined.
• Guessing cook time: Always use visual cues or a timer, not just vibes.
• Overcrowding pans: Give your food some breathing room to crisp properly.

Alternatives & Substitutions

• Ground beef ↔ turkey or plant-based crumbles: turkey lightens the dish; plant-based keeps it vegetarian.
• Pizza sauce ↔ marinara + 1 tsp Italian seasoning: swaps are simple and keep bright tomato flavor.
• Mozzarella ↔ dairy-free shredded cheese for a vegan option (note: texture will change).
• Gluten-free pasta works fine — cook per package instructions and keep an eye on doneness.

Variations & Tips

• Spicy: add 1/2 tsp crushed red pepper to the sauce and use pepperoni with a kick.
• Vegetarian: skip meat, add sliced mushrooms, bell peppers, and black olives.
• Meat-lover’s: toss in cooked Italian sausage, diced ham, and extra pepperoni.
• White pizza twist: swap tomato sauce for a garlic-cream sauce and add spinach and artichoke hearts.
• Kid-friendly: keep pepperoni whole, skip red pepper flakes, and serve with carrot sticks.
• Creative twist: swirl in 1/4 cup pesto before baking for a fresh herb punch.

FAQ (Frequently Asked Questions)

Can I make this ahead of time?

Yes! Assemble the dish, cover tightly, and refrigerate up to 24 hours. When ready to bake, add 5–10 minutes to the baking time if it’s chilled. For longer storage, freeze before baking for up to 2 months; thaw in the fridge overnight then bake.

Can I double the recipe?

Sure thing. Use two 9×13 pans or one larger baking dish. If you use one big pan, add 5–10 minutes to bake time and rotate the pan halfway through for even browning.

Can I substitute butter with oil?

Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil if swapping; for 1 tbsp butter, use about 3/4 tbsp oil.

How do I know it’s done?

Look for bubbling sauce and a cheese top that’s golden and slightly crisp at the edges. The center should be hot and steaming. If you used meat, ensure it reached safe temps during initial cooking — ground meats should reach 160°F.

What if I don’t have ingredient X?

No panic. No pepperoni? Use sliced salami, chopped cooked ham, or extra veggies. Out of mozzarella? Try a blend of shredded cheddar and provolone for good melt and flavor.

How I Like to Serve It

I serve this with a simple green salad dressed in lemon vinaigrette and crusty bread to mop up sauce — comfort plus balance. It works for weeknights, potlucks, or when friends drop by unexpectedly. Pair with a light red wine in cooler months or an icy lemonade in summer. Leftovers make a great next-day lunch; the flavors deepen and the edges get chewier in a good way.

Notes

• Store leftovers in an airtight container in the fridge for up to 4 days; reheat in the oven at 350°F until warmed through, about 15–20 minutes, to keep texture.
• If using raw ground meat, cook to safe temperature of 160°F before combining with pasta.
