How to Make Easy Supreme Pizza Casserole Recipe
Step 1: Prepare the Oven and Cook the Sausage
Start by preheating your oven to 350 degrees to get it ready for baking. In a large skillet over medium-high heat, brown the mild Italian sausage along with minced garlic, breaking the sausage up as it cooks until fully cooked through. This creates a flavorful protein base that’s key to the rich taste of the casserole.
Step 2: Drain and Combine Sausage with Marinara
Once cooked, remove the sausage and garlic with a slotted spoon and drain them on paper towels to manage any excess grease. Leave those delicious drippings in the skillet because they will bring extra flavor to the veggies. Mix the sausage with marinara sauce and salt in a large bowl to create a saucy, savory component that will later top the pasta.
Step 3: Sauté the Vegetables and Combine with Pepperoni and Olives
Using the drippings left in the skillet, sauté the onion, bell pepper, and mushrooms until tender and golden. Then stir in sliced black olives and chopped pepperoni—this mixture will add vibrant texture and the classic taste of pizza veggies and toppings. Set this aside for layering onto the casserole later.
Step 4: Cook the Pasta
Bring a pot of salted water to boil and cook the farfalle pasta according to the package instructions until al dente, which ensures it holds its shape and texture in the casserole. Drain well and transfer to a large bowl for mixing.
Step 5: Make the Creamy Cheese Sauce
In a separate large saucepan, melt unsalted butter over low heat. Whisk in all-purpose flour to create a roux, cooking for about a minute until smooth to remove any floury taste. Gradually whisk in the half and half, raising the heat to medium, and cook until the sauce thickens and bubbles nicely. Then stir in fresh mozzarella, Parmesan cheese, and pepper, whisking until creamy and fully melted—this sauce is what makes the casserole irresistibly cheesy.
Step 6: Combine Pasta and Cheese Sauce, and Layer the Casserole
Pour the cheese sauce over the cooked pasta and stir to coat every bowtie. Transfer this cheesy pasta mixture into a greased 9×13-inch baking dish. Next, spoon the sausage marinara mixture evenly over the pasta. Sprinkle shredded mozzarella on top, then gently layer the sautéed veggies, olives, and pepperoni mixture evenly over everything, creating colorful, delicious layers.
Step 7: Bake Until Bubbly and Golden
Pop the casserole into the oven and bake for 30 minutes until the cheese on top is melted, golden, and bubbly. Let the casserole stand for 5 to 10 minutes before serving—it helps the layers set and makes it easier to scoop out perfect portions of this comforting, crowd-pleasing dish.
How to Serve Easy Supreme Pizza Casserole Recipe

Garnishes
A sprinkle of fresh basil or chopped parsley can add a refreshing pop of color and a hint of herbal brightness, cutting through the rich cheese and meats. A few red pepper flakes are also a great option if you like a little heat on top.
Side Dishes
This casserole pairs perfectly with a crisp green salad tossed in a light vinaigrette to balance the richness. Garlic bread or warm crusty rolls also complement it beautifully, allowing you to soak up every bit of that delicious sauce.
Creative Ways to Present
For parties or potlucks, serve this Easy Supreme Pizza Casserole Recipe in individual ramekins to give each guest their own perfectly portioned cheesy pizza experience. You can also layer it in glass baking dishes to show off the colorful layers and entice everyone before they even dig in.
Make Ahead and Storage
Storing Leftovers
Store any leftover casserole in an airtight container in the refrigerator for up to 3-4 days. This is a fantastic way to enjoy tasty, hassle-free meals throughout the week without any extra prep.
Freezing
This casserole freezes wonderfully! Assemble it completely, then cover tightly with foil and freeze for up to 2 months. When you’re ready, thaw overnight in the fridge before baking as usual to enjoy a comforting meal anytime.
Reheating
Reheat leftovers in the oven at 350 degrees for about 15-20 minutes until hot and bubbly. Microwaving works too for a quicker option, but reheating in the oven keeps the texture and cheese quality at its best.
FAQs
Can I use different types of pasta for this recipe?
Absolutely! While farfalle is recommended to hold the sauce well, other pasta shapes like penne, rotini, or rigatoni will work just fine. Choose your favorite for texture variety.
Is it possible to make this recipe vegetarian?
Definitely! Simply omit the sausage and pepperoni, and load up on extra veggies and perhaps some plant-based sausage alternatives for similar flavor and texture.
Can I prepare the casserole entirely in advance?
Yes, you can assemble the casserole a day before baking. Cover it tightly and refrigerate overnight, then bake it fresh when you’re ready to serve.
What can I substitute for half and half in the cheese sauce?
You can use whole milk combined with a little extra butter for richness or a light cream if you want it even creamier. Just avoid skim milk as it might not create the same creamy texture.
How spicy is this casserole?
This version is mild due to the mild Italian sausage, but you can easily adjust the heat by using spicy sausage, adding crushed red pepper flakes, or topping with spicy pepperoni.
