Ingredients & Why They Work
Each ingredient in this casserole plays a key role, whether it’s creating that rich tomato sauce or adding layers of flavor and texture. When I shop for this, I always pick fresh veggies and good-quality sausage because it really shows in the final dish.
- Fusilli pasta: The twists hold onto sauce and cheese perfectly, so every bite is flavorful.
- Italian sausage: Adds savory depth—sweet or hot sausage works, depending on how spicy you like it.
- Onion: Softens and sweetens the sauce base for balanced flavor.
- Garlic: A must-have for that signature aroma and taste.
- Green bell pepper: Adds freshness and a slight crunch.
- Cremini mushrooms: Earthy flavor that complements the meatiness.
- Kosher salt: Essential for seasoning and bringing out flavors.
- Red pepper flakes: Gives a subtle heat that livens things up.
- Dried basil and oregano: Classic Italian herbs that make the sauce feel authentic.
- Strained tomatoes (or tomato sauce): The rich base that ties everything together.
- Mozzarella cheese: Melts beautifully for that gooey, cheesy finish.
- Pepperoni slices: Adds extra pizza flair and a tasty finishing touch.
Make It Your Way
I like to tweak this casserole recipe depending on what’s in my fridge or what my family’s craving. Maybe toss in some olives or swap the pepperoni for ham — it’s flexible and still delicious.
- Vegetarian version: I once made this with plant-based sausage and added lots of extra mushrooms; it was a hit even with meat-eaters!
- Spice it up: If you want more heat, doubling the red pepper flakes or adding some sliced jalapeños works great.
- Cheese swap: Using a blend of mozzarella and provolone can take the cheesy factor up a notch.
- Seasonal veggies: Try roasted zucchini or spinach when green peppers aren’t your thing.
Step-by-Step: How I Make Cheesy Sausage Pizza Casserole Recipe
Step 1: Cook the pasta ‘al dente’
First things first, get your pasta cooking in a big pot of salted boiling water. I recommend cooking it just ‘al dente’ — that slight firmness keeps it from getting mushy after baking. Drain well and set aside so it’s ready to mix with the sauce.
Step 2: Brown the sausage and sauté the veggies
While the pasta cooks, brown your Italian sausage in a large skillet over medium heat, breaking it up into small, bite-sized pieces. This usually takes 6-8 minutes. Then, toss in your diced onion, garlic, green bell pepper, and mushrooms. Cook until the onions are soft and the mushrooms have released their juices—about 4-6 minutes. This layering builds a rich, hearty flavor foundation.
Step 3: Build the flavorful sauce
Season everything in the skillet with kosher salt, red pepper flakes, dried basil, and oregano. Stir in the strained tomatoes or tomato sauce and simmer gently for 3-4 minutes to let those herbs bloom and mingle with the meat and veggies. This is where the magic happens—the sauce should smell fantastic!
Step 4: Assemble the casserole
Now it’s time to combine. Pour the savory meat sauce over the cooked noodles, add half the pepperoni slices, and mix it all well. Then, in a greased 9x13 inch baking dish, layer half the noodle mixture, sprinkle half the mozzarella, add the rest of the noodles, then top with the remaining cheese and pepperoni. This layering gives you that perfect cheese pull and a crispy, golden top.
Step 5: Bake to bubbly, cheesy perfection
Cover your dish with foil and bake at 350°F for 25 minutes. Then, remove the foil and bake another 15-20 minutes until the casserole is bubbling and the cheese is beautifully browned. Keep an eye on it toward the end—you want that glorious golden topping without burning the edges.
Top Tip
From my cooking adventures with this casserole, I’ve found a few things that make a big difference and help ensure your Cheesy Sausage Pizza Casserole turns out perfectly every time.
- Don’t overcook the pasta: It might sound obvious, but I’ve made the mistake of cooking pasta too long. When baked again, it became mushy. Cooking to al dente is key.
- Brown the sausage well: Getting a nice sear adds depth to the flavor that simple cooked meat can’t match.
- Let the sauce simmer briefly: It helps the spices and herbs meld together, making the sauce more vibrant.
- Cover for most of baking time: This prevents drying out, then uncovered towards the end to get that irresistible bubbly cheese crust.
How to Serve Cheesy Sausage Pizza Casserole Recipe
Garnishes
I usually sprinkle chopped fresh basil or parsley on top for a pop of color and fresh herb flavor. Sometimes a few red pepper flakes added after baking give that extra little kick we all enjoy.
Side Dishes
A crisp green salad with a tangy vinaigrette balances the richness perfectly, and garlic bread or a crusty baguette is always handy for mopping up that delicious sauce.
Creative Ways to Present
For special occasions, I like to bake individual portions in small ramekins—they make cute personal casseroles that look impressive on the table. Alternatively, layering extras like caramelized onions or roasted red peppers adds a gourmet twist.
Make Ahead and Storage
Storing Leftovers
I store leftovers covered in airtight containers in the fridge for up to 3 days. I find the flavors actually deepen overnight, making the next day’s meal even more delicious.
Freezing
This recipe freezes beautifully. I portion it out into freezer-safe containers and store for up to 2 months. Just thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers covered in the oven at 350°F until warmed through, about 20 minutes. To keep the cheese melty, I sometimes add a sprinkle of fresh mozzarella before warming.
Frequently Asked Questions:
Absolutely! While fusilli is great for holding sauce, penne or rigatoni also work well. Just cook the pasta al dente to avoid it becoming mushy during baking.
Yes! You can swap out the sausage for a plant-based meat substitute or simply add extra mushrooms and veggies for a satisfying vegetarian version.
The recipe has a mild kick thanks to the red pepper flakes and spicy sausage option, but you can easily adjust the heat by increasing or skipping the spice to suit your taste.

Ingredients
Pasta
- 12 oz fusilli pasta
Meat
- 1 lb bulk Italian sausage (sweet or hot)
Vegetables & Aromatics
- 1 medium onion, diced
- 3 cloves garlic, minced
- 1 green bell pepper, seeded and diced
- 8 oz cremini mushrooms, quartered
Seasonings & Sauces
- 1 ½ teaspoon kosher salt
- ½ teaspoon red pepper flakes
- 2 teaspoon dried basil
- 1 ½ teaspoon dried oregano
- 3 15-oz cans strained tomatoes (or tomato sauce)
Dairy & Toppings
- 3 cups shredded mozzarella cheese
- ½ cup (about 4 oz) sliced pepperoni
Instructions
- Prepare the pasta: Preheat the oven to 350°F. Grease a 9 x 13-inch baking dish and set it aside. In a large pot of salted boiling water, cook the pasta according to the package instructions until al dente. Drain the pasta and set it aside.
- Cook the sausage: While the pasta is cooking, heat a large skillet over medium heat. Add the Italian sausage and cook, breaking it into small bite-sized pieces, for 6-8 minutes until browned and cooked through.
- Cook the vegetables: Add the diced onion, minced garlic, green bell pepper, and quartered mushrooms to the skillet with the sausage. Cook until the onion is soft and the vegetables are tender, about 4-6 minutes. Stir in kosher salt, red pepper flakes, dried basil, and dried oregano. Pour in the strained tomatoes and stir. Bring the mixture to a simmer and cook for 3-4 minutes. Remove from heat.
- Assemble the casserole: Pour the meat sauce onto the cooked pasta and add half of the sliced pepperoni. Mix well. Spread half of this pasta mixture into the prepared baking dish. Sprinkle half of the shredded mozzarella cheese evenly over the noodles. Add the remaining pasta mixture on top, then finish with the remaining mozzarella cheese and the remaining pepperoni slices.
- Bake: Cover the baking dish with foil and bake in the preheated oven for 25 minutes. Remove the foil and continue baking uncovered for an additional 15-20 minutes, or until the casserole is bubbling and the cheese is starting to brown.
Notes
- Use strained tomatoes for a thicker, richer sauce; tomato sauce can be substituted but may need to be reduced on the stovetop to thicken.
- Adjust the red pepper flakes based on your heat preference, or omit for a milder casserole.
- For a lower-fat option, use ground turkey sausage and part-skim mozzarella cheese.
- Letting the casserole rest for 10 minutes after baking helps it set and makes serving easier.
- Fresh herbs can be substituted for dried, using about three times the amount of fresh herbs.
