One-Pot Cajun Creamy Pasta
This is the kind of dinner that wins over everyone at the table. It’s rich and creamy, with a kick of Cajun spice that keeps each bite exciting. Best of all, you make everything in one pot, so cleanup is a breeze.
The sauce clings to the pasta, the veggies soften just right, and you get that cozy, restaurant-style feel at home. If you’re craving bold flavor without fuss, this is your new go-to.
Why This Recipe Works
- One pot, full flavor: Browning aromatics and spices first builds a deep base, then the pasta cooks directly in the sauce for maximum taste.
- Creamy without being heavy: A mix of broth and cream creates a silky sauce that coats every strand without feeling too rich.
- Balanced heat: Cajun seasoning brings warmth and smokiness, while cream and tomatoes round it out.
- Flexible ingredients: Works with chicken, shrimp, sausage, or a meatless combo—use what you have.
What You’ll Need
- 8 oz (225 g) short pasta such as penne, rigatoni, or rotini
- 1 lb (450 g) protein like sliced andouille sausage, diced chicken thighs, or raw shrimp (peeled and deveined)
- 1 tablespoon olive oil or butter
- 1 small onion, finely chopped
- 1 bell pepper (red or green), sliced into thin strips
- 3 garlic cloves, minced
- 1–1½ tablespoons Cajun seasoning (more or less to taste)
- 1 teaspoon smoked paprika (optional for extra depth)
- 1 can (14.5 oz/410 g) diced tomatoes with juices
- 2½ cups (600 ml) low-sodium chicken broth or vegetable broth
- ¾ cup (180 ml) heavy cream or half-and-half for a lighter version
- ½ cup (50 g) grated Parmesan (plus more for serving)
- Salt and black pepper, to taste
- Fresh parsley or green onions, chopped, for garnish
- Pinch of sugar (optional, to balance acidity if needed)
Step-by-Step Instructions
- Brown the protein: Heat oil in a large, deep skillet or Dutch oven over medium-high. Add sausage or chicken and cook until browned.If using shrimp, season and set aside for later to avoid overcooking.
- Soften the aromatics: Reduce heat to medium. Add onion and bell pepper. Cook 3–4 minutes until softened, scraping up browned bits.Stir in garlic for 30 seconds until fragrant.
- Toast the spices: Sprinkle in Cajun seasoning and smoked paprika. Stir for 20–30 seconds to bloom the spices. This boosts flavor and aroma.
- Add liquids and pasta: Pour in diced tomatoes with juices and broth.Stir, then add the pasta. Bring to a strong simmer and stir well so pasta doesn’t stick.
- Simmer to al dente: Cover partially and cook 9–12 minutes, stirring every couple of minutes. Adjust heat to maintain a steady simmer.Add a splash of broth or water if the pot looks dry.
- Add shrimp (if using): When pasta is almost al dente, stir in shrimp. Cook 2–3 minutes until pink and just cooked through.
- Make it creamy: Reduce heat to low. Stir in cream and Parmesan.Simmer gently 1–2 minutes until the sauce thickens and clings to the pasta. If it’s too thick, add a little broth. If too thin, simmer another minute.
- Season and finish: Taste and add salt, pepper, and a pinch of sugar if the tomatoes are sharp.Turn off heat. Garnish with parsley or green onions and extra Parmesan.
- Serve hot: Ladle into bowls and enjoy immediately while it’s silky and glossy.
Storage Instructions
- Refrigerate: Cool completely, then store in an airtight container for up to 3 days.
- Reheat: Warm over low heat with a splash of broth or milk to loosen the sauce. Stir gently to avoid breaking the cream.

- Budget-conscious: Pantry staples and flexible proteins keep costs down.
- Customizable heat: Dial the Cajun spice up or down to match your crowd.

Pitfalls to Watch Out For
- Overcooking pasta: Stir and check often, especially near the end. Residual heat will finish it.
- Too salty: Use low-sodium broth and season at the end since Cajun blends and Parmesan add salt.
- Curdled sauce: Add cream on low heat and avoid boiling after dairy goes in.
- Sticking: Stir frequently in the first few minutes to keep pasta from clumping on the bottom.
Recipe Variations
- Chicken and Mushroom: Swap sausage for chicken and add sliced cremini mushrooms with the peppers.
- Shrimp and Corn: Fold in thawed corn kernels when adding shrimp for sweetness and texture.
- Veggie-Loaded: Use zucchini, spinach, or kale.Stir leafy greens in at the end until just wilted.
- Lighter Cream: Replace half the cream with Greek yogurt. Temper it with a little hot sauce from the pot before stirring in off heat.
- Extra Smoky: Add a splash of smoked hot sauce or a bit more smoked paprika.
- Cheesy Twist: Mix Parmesan with shredded mozzarella or pepper jack for extra melt and heat.
FAQ
Can I use long pasta like fettuccine?
Yes, but break it in half so it fits the pot and submerges evenly. Stir more often to prevent sticking and adjust liquid as needed.
How spicy is this?
It’s moderately spicy with 1–1½ tablespoons of Cajun seasoning. For less heat, start with 2 teaspoons and add more at the end. For extra kick, add cayenne or hot sauce.
What if the sauce is too thin?
Simmer uncovered for a minute or two, stirring often. The starch from the pasta will naturally thicken it. A small handful of Parmesan also helps.
Can I make it dairy-free?
Use coconut milk or a plain, unsweetened oat creamer and skip the Parmesan or replace it with a dairy-free alternative. Season carefully to balance richness.
What protein works best?
Andouille brings classic Cajun flavor, chicken thighs stay tender, and shrimp cooks quickly. You can also combine sausage with chicken for a heartier dish.
