Let me show you how to bring this amazing comfort food to your table.
Why You’ll Love This Pasta Bake?
- It’s a perfect one-dish meal for any busy weeknight dinner.
- You can easily feed a hungry crowd with this hearty recipe.
- The cheesy, meaty layers are full of incredible, savory flavor.
- It uses simple ingredients you can discover at any grocery store.
- Leftovers taste even better the very next day for lunch.

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.
