Creamy Instant Pot Cajun Chicken Pasta

Instant Pot Cajun Chicken Pasta is a flavorful, speedy dish that’s perfect for Fat Tuesday or any night you want a comforting, mildly spicy meal. It captures classic Cajun seasoning, tender chicken, and a creamy sauce all made quickly in the Instant Pot so you spend less time cooking and more time enjoying the food.

Unlike traditional gumbo or jambalaya, this pasta feels indulgent and more like a true cheat meal—rich, creamy, and satisfying. If you love bold, smoky spices combined with a silky sauce over pasta, this Instant Pot version delivers without the fuss.

This recipe is simple and can be ready in about 30 minutes from start to finish. It’s ideal for a busy weeknight or a festive celebration like Mardi Gras when you want a quick, crowd-pleasing main course. The Instant Pot does most of the work: browning the chicken, softening the aromatics, cooking the pasta, and finishing with a creamy sauce.

Begin by slicing boneless skinless chicken breasts into thin strips. Thin pieces cook quickly and consistently, which is important because the chicken and pasta finish together under pressure. Toss the chicken with your preferred Cajun seasoning until each piece is evenly coated; using a resealable bag makes this step quick and tidy.

Set the Instant Pot to Sauté. When the display reads HOT, add butter and brown the seasoned chicken on all sides. Browning builds flavor and gives the meat a pleasant texture. Once browned, remove the chicken and sauté diced sweet onions in the remaining butter and rendered juices until they are soft and fragrant.

Add minced garlic, salt, ground black pepper, and dried basil, then pour in low-sodium chicken broth. Use a spatula to scrape any browned bits from the bottom of the pot—this deglazing step prevents a burn warning and brings forward richer flavor. Return the chicken to the pot along with chopped sun-dried tomatoes for a sweet-tart contrast.

Add the pasta on top of the mixture in a criss-cross pattern and press it lightly so most of it lies just beneath the surface of the liquid. Important tip: do not stir the pasta into the liquid. Leaving the pasta layered on top helps the Instant Pot come to pressure properly and reduces the chance of a BURN notice.

Instant Pot Cajun Chicken Pasta

DO NOT STIR THE PASTA

Lock the lid and set the valve to SEALING. Pressure cook on HIGH for 5 minutes. The pot will take a few minutes to come to pressure before the countdown begins. After the cook time ends, carefully perform a quick release by moving the valve to VENTING and taking precautions with the steam.

Once the pressure has released and the lid is removed, switch the Instant Pot back to Sauté and pour in heavy whipping cream. Stir continuously until the sauce thickens to your liking, then turn the pot off. Serve immediately and garnish with grated Parmesan cheese if desired.

Cooking Instructions

1. Place chicken and Cajun seasoning in a resealable plastic bag and toss to coat.
2. Turn the Instant Pot to Sauté. When HOT, add butter and brown the chicken on all sides; remove and set aside.
3. Sauté diced sweet onion until tender, then add minced garlic and cook 30 seconds until fragrant.
4. Stir in salt, pepper, dried basil, and chicken broth. Deglaze the pot by scraping any browned bits from the bottom.
5. Return the chicken to the pot, add sun-dried tomatoes, and place pasta on top without stirring. Press pasta down so it is mostly submerged.
6. Close the lid, set the valve to SEALING, and Pressure Cook/Manual on HIGH for 5 minutes. Allow the pot to come to pressure before the timer starts.
7. Carefully quick-release the pressure by moving the valve to VENTING when the cook time finishes. When the pin drops, remove the lid.
8. Switch to Sauté and stir in heavy whipping cream. Cook, stirring often, until the sauce reaches the desired thickness. Turn off the Instant Pot.
9. Serve immediately, garnished with grated Parmesan cheese if you like.

Ingredients

• 4 boneless skinless chicken breast halves, cut into thin strips
• 4 teaspoons Cajun seasoning
• 4 tablespoons butter
• 1/4 cup diced sweet onions
• 1 garlic clove, minced
• 1/2 teaspoon salt
• 1/2 teaspoon dried basil
• 1/4 teaspoon ground black pepper
• 2 cups low-sodium chicken broth
• 3 tablespoons chopped sun-dried tomatoes
• 1/2 pound linguine
• 3/4 cup heavy whipping cream
• 1/2 cup grated Parmesan cheese (for garnish)

Notes and Tips

• Using thinly sliced chicken ensures it cooks quickly and stays tender with the pasta.
• Layering the pasta on top instead of stirring prevents stuck noodles and reduces the chance of a BURN message.
• Adjust Cajun seasoning to your heat preference. Start with less if you prefer milder spice, then add more at the end if needed.
• Deglazing the pot thoroughly after sautéing aromatics is essential to prevent incorrect pressure cooking and to capture flavor from browned bits.
• Serve this dish fresh from the pot; reheating may thin the sauce, so add a splash of cream or broth when warming leftovers.
