Preheat your oven to 375°F (190°C). Yes, this is happening in a hot way.
Sauté the onion and garlic in a skillet until they’re fragrant and a little caramelized. Don’t skip this step—flavor is a friend here.
Add the ground beef or sausage. Cook until browned, breaking it up so it looks like crumbled confetti. Drain excess fat if needed.
Stir in the pizza sauce, Italian seasoning, salt, and pepper. Simmer for 2–3 minutes so everything tastes like a reunion tour of your favorite pizza.
Fold in the cooked pasta, half of the mozzarella, peppers, and pepperoni (or your veggie mix). Mix until everything is evenly coated with sauce. If you’re using veggies, give them a quick sear to wake them up.
Transfer the mixture to a baking dish. Top with the remaining mozzarella and parmesan. It should look indulgently cheesy and a little rebellious.
Bake for 20–25 minutes until the cheese is bubbly and golden. Let it rest for 5 minutes before diving in—resist the irresistible steam burn.
