And when you scoop it out, you get those stretchy cheese pulls and that bubbly, golden top that basically guarantees happy faces at the table. It’s perfect for family dinners, game nights, or anytime you want something comforting that feeds a crowd without a lot of fuss.

Ingredients

• 12 ounces spaghetti

• 1 tablespoon olive oil

• 1 pound Italian sausage (or a mix of sausage and ground beef)

• 1/2 cup pepperoni slices (plus extra for topping)

• 1 small onion, diced

• 2 cloves garlic, minced

• 1 teaspoon Italian seasoning

• 1/2 teaspoon crushed red pepper flakes (optional)

• Salt and black pepper, to taste

• 1 jar (24 ounces) marinara or pizza sauce

• 1/4 cup tomato paste (optional, for a richer flavor)

• 1/2 cup sliced black olives

• 1/2 cup chopped green bell pepper

• 1/2 cup chopped mushrooms

• 2 cups shredded mozzarella cheese

• 1/2 cup grated Parmesan cheese

• Fresh basil or parsley, for garnish

Instructions

1. Cook the spaghetti.
   Bring a big pot of salted water to a boil. Add the spaghetti and cook it until just al dente. Drain it and set it aside.

2. Brown the meat.
   Heat olive oil in a large skillet over medium heat. Add the Italian sausage (and beef if using). Cook until browned and fully done, breaking it up as you go. If there’s a lot of grease, carefully drain the excess.

3. Build the flavor.
   Stir in the onion and garlic. Cook for 2–3 minutes, just until everything softens and smells incredible. Add Italian seasoning, red pepper flakes (if you like a little kick), plus salt and pepper.

4. Make it saucy.
   Pour in the marinara or pizza sauce. If you’re using tomato paste, add it now for a deeper, richer taste. Let it simmer for 5–7 minutes, until it thickens slightly and looks like something you want to eat with a spoon.

5. Mix it all together.
   In a large bowl, toss the cooked spaghetti with the meat sauce. Add black olives, bell pepper, mushrooms, and half of the pepperoni. Stir until it’s nicely combined.

6. Assemble the bake.
   Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Spread in half the spaghetti mixture. Sprinkle on half the mozzarella and a little Parmesan. Add the rest of the spaghetti mixture, then top with the remaining mozzarella.

7. Add the “pizza” finish.
   Arrange extra pepperoni over the top and sprinkle with the remaining Parmesan. This is where it starts looking like your favorite slice—just in casserole form.

8. Bake until bubbly.
   Cover with foil and bake for 20 minutes. Remove the foil and bake another 10 minutes, until the cheese is melted, bubbling, and lightly golden.

9. Rest and serve.
   Let it sit for about 5 minutes (hardest step, honestly). Finish with fresh basil or parsley, then scoop and serve while it’s hot and gooey.

Presentation

• Go for the cheese pull moment: Serve with a wide spatula so each portion lifts out in one satisfying, melty piece.

• Fresh herbs make it pop: A sprinkle of basil or parsley adds color and a fresh, “just made” vibe.

• Extra toppings, pizza-style: A few extra pepperoni cups on top look fun and irresistible.

• Serve with something crisp: A simple green salad or garlicky roasted veggies balances all that cheesy goodness perfectly.
