Instructions

Cook Spaghetti Noodles

Begin by boiling the spaghetti in a large pot of salted water according to package instructions until al dente. This ensures the noodles have a firm bite that will hold up under baking and mix well with the sauce. Once cooked, drain thoroughly and set aside to prevent sogginess.

Sauté Ground Beef and Vegetables

While the pasta cooks, heat a large skillet over medium-high heat. Add ground beef, diced red onion, sliced mushrooms, and diced bell pepper to the skillet. Sauté until the beef is fully browned and the vegetables are softened, enhancing natural flavors. Drain any excess fat for a healthier dish without sacrificing taste.

Season Meat and Veggies

Mix in Italian seasoning, onion powder, garlic powder, and seasoned salt. These spices infuse the beef and vegetables with classic Italian-inspired flavor, providing depth and balance that complements the pizza and pasta sauces.

Add Sauces and Proteins

Next, stir in most of the pepperoni slices, the majority of the bacon crumbles, pizza sauce, and pasta sauce. Combining these ingredients melds the pizza and pasta elements to create a rich, flavorful sauce that simmers together, allowing the meats and spices to harmonize fully over 3–5 minutes.

Combine Pasta with Sauce

Add the drained spaghetti into the skillet and toss thoroughly to coat every strand evenly in the sauce mixture. This step ensures each bite carries the signature blend of meaty, saucy goodness without clumps or dry spots.

Prepare for Baking

Transfer the spaghetti and sauce mixture to a baking dish with even spreading. Sprinkle shredded mozzarella cheese evenly over the top to create a melty, golden crust. Garnish with the remaining bacon, diced onions, black olives, diced bell peppers, and leftover pepperoni slices for added texture and visual appeal.

Bake and Broil

Bake the casserole in a preheated oven at 175°C (350°F) for 10 minutes to allow the flavors to meld and the cheese to melt fully. Then switch to broil for 2–3 minutes to brown the cheese and create a bubbling, golden crust, enhancing both aroma and texture.

Serve Warm

Remove from the oven carefully and let cool slightly before serving. This warms every bite and ensures the cheese is perfectly gooey, making the dish ready to be enjoyed.

You Must Know

  • You can easily substitute Italian sausage for ground beef to add a different flavor profile.
  • Feel free to customize with your favorite pizza toppings like jalapeños, extra cheese, or fresh basil.
  • Ensure the cheese is evenly spread for maximum melt and browning in the final baking step.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and warm in the oven to maintain texture and avoid drying out.

Serving Suggestions

This dish pairs wonderfully with a simple green salad tossed in a light vinaigrette or some garlic bread for added indulgence. A glass of sparkling water or a light red wine complements the savory richness perfectly.

Professional Tips

  • Drain cooked ground beef well to prevent excess grease in the bake.
  • Use a mix of pizza and pasta sauce to balance tanginess and sweetness, enhancing flavor complexity.
  • Add heavier toppings on top for texture contrast instead of mixing all inside.
