How to Make Loaded Pizza Spaghetti Bake Recipe
Step 1: Cook Pasta
Start by preparing your spaghetti noodles in well-salted boiling water. Cook them until al dente so they have that perfect bite and can hold onto the sauce without becoming mushy. Drain and set aside to keep ready for combining later.
Step 2: Brown Meat & Vegetables
Warm a large skillet over medium-high heat and add ground beef along with diced red onions and sliced mushrooms. Sauté until the beef is thoroughly browned and the veggies have softened, then drain any excess fat for a cleaner, less greasy bake.
Step 3: Season Mixture
Incorporate Italian seasoning, onion powder, garlic powder, and seasoned salt into your skillet mix. These spices elevate the ground beef and vegetables with savory and aromatic notes that are essential to this dish’s delicious profile.
Step 4: Incorporate Sauces & Bacon
Next, add several slices of pepperoni and most of your cooked bacon crumbles to the skillet. Stir in both pizza sauce and pasta sauce, then let everything simmer gently so the flavors blend and the sauce thickens slightly.
Step 5: Combine Pasta and Sauce
Return the cooked spaghetti to the skillet and toss thoroughly to evenly coat every strand in that rich, flavorful sauce, along with the meat and vegetable mixture. This step ensures harmony between pasta and sauce.
Step 6: Assemble and Top
Sprinkle the shredded mozzarella cheese generously over the saucy pasta, then add the remaining bacon, diced onions, black olives, mushrooms, and pepperoni slices on top. This layering builds that iconic loaded pizza texture and look.
Step 7: Bake and Broil
Transfer everything to a baking dish and bake in a preheated 175°C oven for 10 minutes. Then broil for an additional 2 to 3 minutes until the cheese is bubbling, melted, and golden brown on top—making the finish irresistibly crispy and cheesy.
How to Serve Loaded Pizza Spaghetti Bake Recipe

Garnishes
Fresh garnishes like chopped basil or a sprinkle of crushed red pepper flakes add a bright, fresh contrast to the richness of this dish. A drizzle of extra virgin olive oil before serving can also elevate the mouthfeel and aroma beautifully.
Side Dishes
Pair your Loaded Pizza Spaghetti Bake with a crisp green salad tossed in a tangy vinaigrette or crunchy garlic bread. Both sides bring refreshing textures that complement the warming, cheesy bake perfectly.
Creative Ways to Present
Serve this dish family-style straight from the baking dish for cozy gatherings, or portion it into individual ramekins for a fun presentation. You can even add a dollop of ricotta or a sprinkle of parmesan on top for extra decadence just before serving.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer leftovers into an airtight container and store them in the refrigerator. They will keep well for up to 3 days and maintain much of their flavor and texture.
Freezing
You can freeze the baked spaghetti in a suitable container for up to 2 months. Thaw in the refrigerator overnight before reheating to preserve the taste and structure.
Reheating
Reheat leftovers in the oven at 175°C for about 15-20 minutes or until hot and bubbly. Microwaving works too, but baking helps restore that crispy cheese topping and prevents sogginess.
