One Pot Cajun Pasta Recipe: Spicy Andouille and Creamy Sauce

This one-pot dish brings bold Cajun flavors and creamy comfort to your weeknight table. I developed this recipe during my Asheville farm-to-table days, perfecting the balance between spicy andouille and velvety sauce.

The beauty lies in its simplicity—everything cooks together in one pot, allowing the pasta to absorb the rich, spiced sauce. David, my official taste-tester, declared this his favorite after the first bite.

What emerges is tender pasta coated in a creamy, smoky sauce with perfectly cooked andouille. The flavors build as it simmers, creating a dish that tastes far more complex than its easy preparation.

Ready in about 30 minutes, this delivers restaurant-quality results with minimal cleanup. Here’s how to make it.

Ingredients for One Pot Cajun Pasta

Bold Cajun flavors meet creamy comfort in this simple one-pot wonder with familiar ingredients.

The andouille is non-negotiable—look for Aidells or Johnsonville at Whole Foods or your butcher. They’ve got the right spice balance and fat content. If you’re in Asheville, hit up Chop Shop for their house-made version (worth the drive). The cream needs to be full-fat for that velvety finish—skip the light versions. Penne works best since it traps the sauce in its ridges.

No andouille? Kielbasa in a pinch (add extra Cajun seasoning). Fresh out of heavy cream? Half-and-half plus a pat of butter gets you close. The bell pepper can be swapped for green or orange—just keep the color vibrant. For the broth, homemade or Better Than Bouillon are my go-tos. If you’re gluten-free, cornstarch instead of flour thickens just as well.

Leftovers keep 3-4 days in the fridge—reheat gently with a splash of broth. Freezes for 2 months (the sauce might separate slightly but stirs back together). I always double the batch for quick dinners later in the week (trust me, you’ll want seconds).

Step-by-Step Instructions for One Pot Cajun Pasta

Here’s the method. Everything cooks in one pot for maximum flavor and easy cleanup.

Step 1: Sauté the Aromatics and Andouille

Heat the 2 tbsp olive oil in a large, deep skillet or Dutch oven over medium-high heat until it shimmers. Add the diced yellow onion and cook for 3-4 minutes until it starts to soften and turn translucent at the edges.

Add the sliced andouille sausage and diced red bell pepper. Cook for 5-6 minutes, stirring occasionally, until the sausage begins to brown and the pepper softens slightly. The andouille will release its smoky, spicy oils into the pan, building the flavor base for your dish.

Stir in the minced garlic cloves and cook for 30 seconds until fragrant. Be careful not to let it burn—garlic goes from perfect to bitter in seconds.

Step 2: Build the Sauce Base

Sprinkle the 2 tbsp all-purpose flour over the sausage and vegetable mixture. Stir well to coat everything evenly, then cook for 1-2 minutes to remove the raw flour taste. This creates a roux that will thicken your sauce beautifully.

Gradually pour in the 2 cups chicken broth, stirring constantly to prevent lumps from forming. Add the 1.5 cups heavy cream, then stir in the 2 tbsp Cajun seasoning, 1 tsp smoked paprika, 1 tsp dried thyme, and 1 tsp dried oregano.

Bring the mixture to a gentle simmer, then reduce the heat to medium. Let it cook for 3-4 minutes until it begins to thicken slightly.

Step 3: Cook the Pasta in the Sauce

Add the 8 oz penne pasta to the skillet, pressing it down into the sauce so it’s mostly submerged. Stir well to distribute the pasta evenly. If the liquid doesn’t quite cover the pasta, add a splash of water—just enough to help it cook through.

Season with the 1 tsp salt and 0.5 tsp black pepper. Cover the skillet and let the pasta cook for 10-12 minutes, stirring every 3-4 minutes to prevent sticking. The pasta should become tender and the sauce should thicken to a creamy consistency that clings to each piece.

If the sauce becomes too thick before the pasta is done, add a little more water or broth, ¼ cup at a time, and stir well.

Step 4: Finish and Serve

Once the pasta is cooked al dente and the sauce has thickened, remove the skillet from the heat. Let it sit for 2 minutes to allow the sauce to set slightly. The pasta will absorb some of the liquid as it rests, creating a perfectly creamy texture.

Give it one final stir to redistribute the sauce, then taste and adjust the seasoning if needed. The Cajun seasoning should provide a bold, spicy kick, while the smoked paprika adds depth. Serve immediately in shallow bowls, garnished with extra herbs if desired.

Wine and Beer Pairings for These Flavors

Bold Wine Choices

A crisp Sauvignon Blanc from New Zealand cuts through the creaminess with its bright acidity and citrus notes. The grassy, herbal undertones complement the Cajun spices beautifully. I always reach for Kim Crawford when I’m at Central Market. 🍷

Rich Red Options

If you prefer red, a medium-bodied Zinfandel with its jammy fruit and spice notes stands up to the bold flavors. Look for Ravenswood from California. The peppery finish mirrors the dish’s spice profile.

Texas Favorites

For local flair, try a Texas Viognier from William Chris Vineyards. Its stone fruit notes and subtle oak balance the andouille’s smokiness perfectly. David and I discovered this pairing at a Hill Country vineyard.

Beer Pairings

A crisp Pilsner like Shiner Bock cleanses your palate between bites. The light malt sweetness contrasts the heat while the carbonation cuts through the cream. For craft lovers, Live Oak Hefeweizen offers banana-clove notes that work surprisingly well. 🍺

Dark Beer Alternative

A Brown Ale with its caramel and nutty notes can complement the dish’s smoky elements. New Belgium Fat Tire is my go-to when I want something with more body. The malt sweetness balances the spice.

Non-Alcoholic Option

For a booze-free choice, try sparkling water with a lime wedge. The effervescence refreshes your palate, while the citrus brightens the rich sauce. I keep Topo Chico in my fridge for just this purpose.
