Cajun Sausage Pasta (Viral Sausage Pasta Recipe)

This creamy Cajun sausage pasta is smoky, savory, and just spicy enough, with browned sausage and shell pasta coated in a Parmesan Cajun sauce. The pasta cooks right in the chicken broth, so everything comes together in one skillet and the sauce gets extra flavorful from the starch in the pasta. It’s quick, filling, and built for an easy weeknight dinner.

Why You'll Love This Cajun Pasta with Sausage

I’m always up for a good Cajun pasta. My Cajun steak pasta and Cajun chicken bacon ranch pasta are two recipes I always find myself making, so when I saw @cookingwithkatiecross making a viral Cajun pasta with sausage, I knew I wanted to try my own version.

Smoked sausage is a great fit here because it already brings so much flavor to the pan before the sauce even comes together. Once you add the Cajun seasoning, Parmesan, and a little cream, you get a sauce that’s rich and savory with just enough spice to keep you wanting more.

What I really love about this recipe, though, is the one-pan method. The shells cook directly in the broth, so they pick up more flavor as they soften and help thicken the sauce at the same time. You end up with a really satisfying pasta without boiling noodles in a separate pot or making a complicated sauce.

Ingredients

• ½ lb. smoked sausage, diced
• ½ cup yellow onion, diced
• 2 cups large shell pasta
• 3 cups chicken broth
• ¼ cup heavy whipping cream
• 1 cup parmesan cheese, shredded
• 1 tbsp. tomato paste
• 1 tsp. onion powder
• 1 tsp. garlic powder
• 1 tsp. Cajun seasoning

Ingredient Notes and Substitutions

• Smoked sausage: Smoked sausage gives the pasta a lot of flavor without needing much extra seasoning. Andouille is a great option if you want a stronger Cajun flavor and a little more heat.
• Shell pasta: Large shells work especially well because they catch the creamy sauce and little pieces of sausage. Penne, rotini, or cavatappi are all good substitutes.
• Cajun seasoning: Cajun blends vary quite a bit in salt and spice. Start with the measured amount, then taste the sauce before adding more.
• Parmesan: Freshly grated Parmesan melts into the sauce much more smoothly than pre-shredded cheese. It also adds enough saltiness that I’d wait until the end before adding extra salt.
• Heavy cream: You only need a small amount because the starchy broth already gives the sauce body. Half-and-half can work, but the sauce will be a little lighter.

How to Make Cajun Sausage Pasta

Step 1: Brown the Sausage and Onions

Heat a large skillet over medium-high heat. Add the smoked sausage and diced onion and cook until the sausage is browned around the edges and the onion is softened. Transfer both to a plate and set aside.

Step 2: Toast the Tomato Paste

Add the tomato paste to the same skillet along with the dry shell pasta. Cook for about 1 minute, stirring often, until the tomato paste darkens slightly and starts coating the pasta.

Step 3: Cook the Pasta

Pour in the chicken broth and stir well, scraping up any browned bits from the bottom of the skillet. Bring to a simmer and cook until the pasta is al dente and most of the broth has been absorbed.

Step 4: Make the Cajun Cream Sauce

Reduce the heat to low. Stir in the Cajun seasoning, onion powder, garlic powder, heavy cream, and Parmesan. Keep stirring until the cheese melts and the remaining broth turns into a creamy sauce that coats the shells.

Step 5: Finish the Pasta

Return the sausage and onions to the skillet and toss everything together until evenly combined. Let it sit for a minute or two so the sauce can settle around the pasta, then serve hot.

Tips for the Best Cajun Sausage Pasta

• Use a wide skillet. It gives the pasta room to cook evenly and helps the broth reduce at the right pace.
• Watch the liquid level. If the pasta looks dry before it’s tender, add a splash of broth or water so the bottom doesn’t scorch.
• Stop at al dente. The pasta keeps cooking while you finish the sauce, so don’t let it get completely soft beforehand.
• Lower the heat before adding the cream and Parmesan. This helps the cheese melt smoothly instead of clumping or separating.
• Taste before adding salt. The sausage, broth, Parmesan, and Cajun seasoning all bring plenty of salt on their own. I don't like adding any extra.
• Loosen the sauce if needed. If it thickens too much as it sits, stir in a splash of warm broth or cream before serving. Adding a little cream is my favorite.

How to Store Cajun Sausage Pasta

• In the fridge: Store leftovers in an airtight container in the refrigerator for up to 4 days. The sauce will thicken as the pasta sits.
• To reheat: Warm gently in a skillet over low heat with a splash of chicken broth, milk, or cream to loosen the sauce. You can also microwave individual portions in short intervals, stirring between each.
• In the freezer: I don’t recommend freezing this one. Creamy pasta sauces can separate after thawing, and the shells tend to lose their texture.

Cajun Sausage Pasta FAQs

Is Cajun sausage pasta spicy?

That depends mostly on the Cajun seasoning and sausage you use. Some Cajun blends are mild while others contain quite a bit of cayenne. For a milder pasta, use smoked sausage and a mild seasoning blend. For more heat, use andouille and add extra Cajun seasoning or red pepper flakes.

Can you cook pasta directly in the sauce?

Yes. Cooking the dry pasta directly in the chicken broth is one of the reasons this recipe works so well in one pan. As the shells cook, they release starch into the broth, which helps give the finished Parmesan sauce more body.

Can I use a different pasta shape?

Yes. Penne, rotini, cavatappi, rigatoni, or medium shells can all work. Stick with a short pasta and keep an eye on the liquid since different shapes and brands can absorb broth at different rates.

Why did my Cajun pasta sauce get too thick?

The pasta continues absorbing liquid even after it finishes cooking, so the sauce naturally thickens as it sits. Stir in a splash of warm chicken broth, milk, or cream until it loosens back to the consistency you want.

Can I add vegetables to Cajun sausage pasta?

Definitely. Bell peppers are an especially good addition and work well with Cajun seasoning and smoked sausage. Mushrooms, spinach, or diced tomatoes can also be added. Cook vegetables that release a lot of moisture before finishing the cream sauce.

Is Cajun sausage pasta a traditional Cajun recipe?

Not exactly. Creamy Cajun sausage pasta is better described as a Cajun-inspired pasta dish. It uses flavors associated with Cajun cooking, such as smoked or andouille sausage and Cajun seasoning, but creamy Parmesan pasta itself isn’t a traditional Cajun dish.

What goes well with Cajun sausage pasta?

Since the pasta is already rich and filling, I like serving it with something simple such as roasted broccoli, sautéed green beans, asparagus, garlic bread, or a crisp green salad. A lighter side balances the creamy sauce especially well.
