Let’s break down the process so anyone—novice or expert—can confidently create a creamy, cheesy, hearty baked rotini casserole.
Prepare everything ahead: measure out the cheese, pre-slice your sausage or any vegetables, and preheat your oven to 350°F (or as specified)245.
Shopping list for a classic rotini casserole:
16 oz rotini pasta
4 cups marinara sauce
15 oz ricotta cheese or 16 oz cottage cheese
1-2 cups shredded mozzarella cheese
4 oz grated Parmesan
1 egg
12 oz Italian sausage or 1 lb ground beef (optional)
1 tbsp olive oil
1 tsp each: dried basil, oregano, onion powder, garlic powder
Salt and pepper to taste
Bring a large pot of salted water to a boil.
Add rotini and cook just to al dente—about 1-2 minutes less than the package directions (the pasta will finish cooking in the oven and become perfectly tender this way)24.
Drain well and set aside, reserving about ½ cup of the pasta water to moisten if needed4.
:
Brown the sausage or beef in a hot skillet with a drizzle of olive oil.
If using sausage, slice into half-inch pieces and brown until nicely crusted, about 5-6 minutes2.
For ground beef, cook until no longer pink, crumble as it cooks, then drain excess fat7.
:
Sauté chopped veggies in a bit of olive oil until softened, about 4-6 minutes58.
Season with salt, pepper, and herbs as they cook.
In a medium bowl, mix ricotta (or cottage cheese) with one egg, salt, basil, oregano, onion and garlic powder, and half the grated Parmesan247. The egg helps bind the cheese and gives a creamy, custard-like middle.
For more richness, add some chopped parsley or fresh spinach.
In a large mixing bowl or directly in your pasta pot, combine the drained rotini, cooked protein or veggies, most of the marinara sauce, and half the mozzarella. Stir well to coat—using a splash of reserved pasta water if the mixture seems dry24.
This ensures even flavor and helps everything bond as it bakes.
Lightly grease a 9x13-inch baking dish with olive oil or nonstick spray.
Layer half the rotini mixture into the dish.
Dollop and gently spread the ricotta cheese mixture over the first layer.
Add the remaining rotini mixture on top.
Finish with a final layer of mozzarella and the rest of your Parmesan. For an even richer dish, tuck slices of provolone or another favorite cheese between layers8.
Cover your dish loosely with foil and bake in the center of a preheated oven at 350°F (175°C) for about 30-40 minutes48.
Remove foil and continue baking for another 10-15 minutes, until the top is golden and bubbly, cheese is fully melted, and you see sauce bubbling at the edges247.
For a crisp, browned cheese topping, broil for 1-2 minutes at the end (watch closely!).
Let the casserole sit for at least 10 minutes before slicing; this helps it hold together.
Sprinkle with fresh parsley, basil, or cracked pepper.
Baked rotini casserole is incredibly flexible. Here are creative ways to put your own spin on this dish:
: Add sautéed mushrooms, spinach, zucchini, or eggplant for a healthy lift5.
: Use a blend of sausage, ground beef, or shredded rotisserie chicken25.
: Layer in provolone, gouda, or smoked mozzarella for more flavor.
: Add red pepper flakes or use spicy Italian sausage for a kick2.
: Try plant-based cheese and meat alternatives, and use a vegan ricotta or tofu blend.
: Use gluten-free rotini for a celiac-friendly casserole.
: Coating the pasta in sauce before layering ensures even flavor.
: Freshly shredded cheese melts better and tastes richer.
: For extra creaminess, consider spreading the ricotta cheese between pasta layers rather than mixing it all in.
: Allowing the casserole to sit after baking helps it slice neatly.
One of the best aspects of this dish is how well it keeps:
: Assemble the casserole up to the point of baking. Cover tightly and refrigerate for up to 24 hours. When ready to bake, allow a few extra minutes in the oven since it’s coming from the fridge245.
: Assemble (unbaked), wrap well with plastic and foil, and freeze for up to three months. Thaw overnight in the fridge before baking as usual.
: Store portions in airtight containers in the fridge for up to four days. Reheat in the microwave or oven covered with foil until hot throughout.
: Sautéed garlic or shallots, fresh herbs, and a hint of red pepper give the sauce depth.
: Reserve a small amount of sauce to drizzle over the casserole before the final cheese layer for added moisture6.
: Dollop between layers for unexpected tang and richness8.
: Parmesan is salty, so taste as you go and adjust the salt accordingly.
: Don’t be afraid to mix and match cheeses, meats, or vegetables based on your favorite flavors.
Baked rotini casserole is rich and filling, so simple sides work best:
