Ingredients You’ll Need

Here’s a look at the simple stuff you’ll need to grab from the store.

Short pasta: I love rigatoni because the sauce gets stuck inside the tubes, but you can also use ziti, penne, or rotini!
Italian sausage: I usually get the mild kind, but you can turn up the heat with a spicy Italian sausage if you like.
Small onion: This adds a nice, sweet flavor base that makes a difference. You’ll want to dice it up small.
Ricotta cheese: This is the secret to the creamy filling. It makes the whole dish feel so rich and wonderful.
Parmesan cheese: You’ll want some freshly grated Parmesan. It adds a salty, nutty bite that you can’t get from the can.
Mozzarella cheese: I use some in the filling and save the rest for that bubbly, golden top.
Italian seasoning: This is my go-to shortcut for that classic Italian flavor without measuring out various herbs.
Garlic cloves: Freshly minced garlic is a must for me. It provides that amazing aroma and a punch of great flavor.
Red pepper flakes: Just a little pinch wakes everything up. You can add more or less depending on how spicy you like things.
Fresh basil: There’s nothing like fresh basil to brighten a pasta dish. Chop some for the sauce and save a bit for the top.
Large egg: I mix an egg into the ricotta cheese. It helps bind the cheese together so it doesn’t get runny when you bake it.
Marinara sauce: Use your favorite brand or a homemade one; it tastes fantastic in this pasta bake.

How to Make Italian Sausage Pasta Bake?

This recipe comes together quickly, perfect for preparing a delicious dinner without fuss.

Step 1: Cook the pasta until it’s a little firm. It will finish cooking in the oven, so don’t overdo it.

Step 2: Brown the sausage with the onion in a large skillet. Break up the meat as it cooks until it’s nicely crumbled.

Step 3: Stir in the aromatics, which are your garlic and seasonings. Cook for just a minute until you can smell that amazing garlic.

Step 4: Add the marinara sauce to the skillet with the sausage. Let it simmer gently while you prepare the cheese mixture.

Step 5: Mix the cheese filling by combining the ricotta, Parmesan, egg, and half of the mozzarella in a separate bowl.

Step 6: Combine everything in a large bowl. Gently mix the cooked pasta, the sausage sauce, and the creamy ricotta mixture all together.

Step 7: Assemble your bake by pouring the pasta mixture into a baking dish. Spread it out evenly for perfect cooking.

Step 8: Top with cheese and bake until hot, bubbly, and golden brown. Let it rest for a few minutes!

Tips for the Best Italian Sausage Pasta Bake

Here are a few little tricks I’ve learned to ensure this dish turns out perfectly every time.

Don’t overcook your pasta at first. Cooking it al dente prevents it from becoming mushy in the oven.
Use freshly grated cheese if you can. It melts so much better and has a much richer flavor.
Let the pasta bake rest for 10 minutes. This step helps the layers set, making it easier to serve.
You can drain the fat from the sausage. I do this for a lighter, non-greasy dish.
Don’t be shy with the fresh basil. It adds a wonderful freshness that cuts through the richness.

Variations and Substitutions

Want to change things up? Here are some simple and tasty ideas for making this dish your own.

Try using ground turkey or chicken sausage for a lighter, leaner version of this delicious pasta bake.
You can easily add some vegetables. Sautéed spinach or mushrooms would be a fantastic addition to the mix.
Swap the ricotta cheese with cottage cheese if that’s what you have in your fridge.
Use a spicy arrabbiata sauce instead of the traditional marinara sauce for a different flavor.
Try a different blend of cheeses. A mix with provolone would give it a nice, smoky flavor.

Make-Ahead and Storage Tips

Italian sausage pasta bake is a great dish to prep, perfect for busy schedules or planning a party.

To make ahead: You can assemble the casserole, cover it tightly, and refrigerate it for up to 2 days.
For leftovers: Store any leftovers in an airtight container in the refrigerator. They will stay good for up to 4 days.
To freeze the bake: Assemble the pasta bake in a freezer-safe dish, cover it well, and you can freeze it for 3 months.
Reheating from frozen: You can bake it straight from the freezer. Just add about 20-30 extra minutes to the baking time.
Reheating leftovers: The microwave works great for single servings, but you can also use the oven for larger portions.

What to Serve with Italian Sausage Pasta Bake?

This dish is a complete meal on its own, but a little something on the side is always a nice touch.

A simple green salad: I like to serve a crisp salad with a light vinaigrette to balance the richness of the pasta.
Warm garlic bread: You need something to mop up every last bit of that amazing sauce, and garlic bread is perfect.
Steamed green beans: A side of simple steamed or roasted green beans with a bit of lemon adds a fresh touch.
Roasted broccoli: I often roast some broccoli with garlic and olive oil. It’s a simple and healthy side dish.
