Save this recipe on:

I have a deep love for hearty pasta dishes, and this One-Pot Creamy Sausage Rigatoni is the very definition of weeknight comfort. It’s saucy, rich, savory, and loaded with bold Italian sausage flavor — everything I want when I need something deeply satisfying, but don’t want a sink full of dishes afterwards. It all comes together in a single pot, which makes it even more perfect for cozy nights or busy evenings.

The first time I made this, I was blown away by how the rigatoni absorbed the flavors of the sausage and creamy tomato base as it cooked. There’s just something magical about pasta cooked right in the sauce — no draining, no fuss, just full-on flavor from the first bite to the last. I added a few handfuls of fresh spinach and let it wilt into the sauce for a bit of green, and of course, a generous sprinkle of cheese because no creamy pasta is complete without it.

One-pot meals are my go-to, and this one hits all the marks: fast, filling, flavorful, and family-approved. Whether you’re feeding a crowd or just want delicious leftovers for the next day, this rigatoni has your back. And trust me, once you make it, it’s going straight into your regular rotation.

Why You’ll Love This One-Pot Creamy Sausage Rigatoni

This recipe checks every box for a winning dinner. It’s creamy without being too heavy, and the Italian sausage adds a wonderful richness and spice. Because the pasta cooks directly in the sauce, every tube of rigatoni is infused with flavor. Plus, it only uses one pot, making cleanup a breeze — no colander, no extra saucepan, just one big, bubbling pot of goodness. Whether you’re cooking for a family or prepping for the week ahead, this is a recipe you’ll come back to again and again.

How to Make One-Pot Creamy Sausage Rigatoni

Step 1: Start by browning the Italian sausage in a large, deep skillet or Dutch oven over medium heat. Break it apart with a wooden spoon as it cooks until it’s fully browned and slightly crispy in spots. Don’t drain it — you want all that flavorful fat in the pot.

Step 2: Add in your diced onions and minced garlic. Let them sauté in the sausage fat until softened and fragrant. This is the foundation of flavor that makes the sauce so rich.

Step 3: Stir in crushed tomatoes and a splash of chicken broth. Add in uncooked rigatoni directly into the pot, making sure it’s submerged. Cover and simmer, stirring occasionally, until the pasta is cooked al dente and has soaked up most of the liquid.

Step 4: Once the pasta is tender, reduce the heat and stir in heavy cream and a handful of freshly grated Parmesan. Let the sauce thicken slightly — it should coat the rigatoni without being too soupy.

Step 5: Add in a few handfuls of fresh spinach and stir until it wilts. Taste and adjust salt, pepper, or even a pinch of chili flakes if you want extra heat.

Step 6: Finish it off with more Parmesan and fresh basil or parsley for a hit of brightness. Serve hot and bubbly, straight from the pot.

Recipe Variations and Possible Substitutions

There’s plenty of room to make this recipe your own. If you don’t eat pork, swap the Italian sausage for turkey or chicken sausage — or go for a spicy plant-based version if you’re keeping it vegetarian. Want to boost the veggies? Toss in mushrooms, zucchini, or red bell peppers with the onions.

For a dairy-free version, use coconut milk or a cashew cream substitute and skip the cheese or use a plant-based alternative. You can also use penne, fusilli, or any short pasta you have on hand. Just be mindful of cooking times, as some pasta shapes may cook faster or slower than rigatoni.

If you’re short on time, use jarred marinara instead of crushed tomatoes and broth — it still tastes great and shaves off a few minutes. This recipe is incredibly adaptable to whatever’s in your pantry or fridge.

Serving and Pairing Suggestions

One of my favorite things about this rigatoni is how satisfying it is on its own, but if you want to make it a full spread, pair it with a fresh green salad drizzled in balsamic vinaigrette or a zesty lemon dressing. A crusty loaf of garlic bread or some warm focaccia on the side is never a bad idea, especially for scooping up every last bit of sauce. If you’re feeling fancy, serve it with a glass of Chianti or your favorite red — it holds up beautifully against the richness of the dish.

Storage and Reheating Tips

To store leftovers, let the pasta cool completely and transfer it to an airtight container. It will keep well in the fridge for up to 4 days. When reheating, add a splash of broth, water, or cream to loosen up the sauce and keep it creamy — microwave on medium or warm it gently on the stovetop. Avoid overheating to prevent the sauce from separating.

This rigatoni is also freezer-friendly. Store it in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating, and again, add a bit of liquid to revive the creamy texture.

Frequently Asked Questions

What type of sausage is best for this recipe?

I recommend using spicy or sweet Italian sausage, depending on your heat preference. You can also use bulk sausage or remove the casings from links.

Can I use a different type of pasta?

Yes, penne, ziti, or any other short, sturdy pasta will work. Just keep an eye on the cooking time — thinner pastas may cook more quickly.

How can I make this dish vegetarian?

You can easily swap the sausage for a plant-based version or use sautéed mushrooms and lentils for a hearty texture. Use vegetable broth instead of chicken broth, and dairy-free cream and cheese if needed.

Is this dish spicy?

Not necessarily. If you use sweet Italian sausage and skip the chili flakes, it’s quite mild. You can control the spice level by the type of sausage you choose.

Can I prep this ahead of time?

Absolutely! You can make the full dish ahead and refrigerate or freeze it. It reheats well, and even tastes better the next day as the flavors develop further.
