Crock Pot Creamy Cajun Chicken Pasta
I remember the first time I made this Crock Pot Creamy Cajun Chicken Pasta—my kitchen smelled like a New Orleans bistro and dinner practically made itself while I handled emails and homework. It’s a comforting, saucy pasta loaded with tender, shredded Cajun-spiced chicken, sweet bell peppers, and a creamy Parmesan finish. If you like one-pot comfort food that’s hands-off but full of flavor, this hits the spot. For another quick stovetop version you can try when you don’t want to use the slow cooker, I often recommend the Creamy Cajun Chicken skillet.
Why you’ll love this dish
This recipe gives you big, bold Cajun flavor with minimal effort. The slow cooker gently breaks down chicken into tender shreds while the tomatoes and broth build a flavorful base, then a splash of cream and Parmesan transforms everything into a silky sauce that clings to pasta. It’s perfect for busy weeknights, feeding a family, or bringing to potlucks—comforting, crowd-pleasing, and easy to scale.
“A busy weeknight lifesaver—zesty, creamy, and everyone asks for seconds.”
It’s also flexible: swap pasta shapes, adjust heat with more or less Cajun seasoning, or stretch the meal with extra veggies. If you want another creamy Cajun pasta option with slightly different spice balance, see this creamy Cajun chicken pasta recipe for inspiration.
How this recipe comes together
- Season and lightly brown the chicken to lock in flavor.
- Layer chicken, peppers, onions, tomatoes, and broth in the slow cooker.
- Slow-cook until the chicken is tender, then shred.
- Stir in cream and Parmesan for a rich sauce.
- Toss with al dente pasta and heat together briefly so the pasta soaks up the sauce.
This overview keeps things simple: the slow cooker does the heavy lifting, while quick finishing steps add creaminess and texture.
Gather these items
- 1 lb boneless, skinless chicken breasts
- 2 tablespoons olive oil
- 1 tablespoon Cajun seasoning (store-bought or homemade)
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 bell pepper, sliced (any color)
- 1 small onion, thinly sliced
- 3 cloves garlic, minced
- 1 (14.5 oz) can diced tomatoes, with juices
- 1 cup chicken broth
- 1/2 cup heavy cream
- 1/2 cup grated Parmesan cheese
- 8 oz penne pasta (or pasta of choice)
- Fresh parsley, chopped for garnish
Notes and substitutions:
- Use light cream or half-and-half for a lighter sauce (sauce will be a touch thinner).
- If you prefer lower sodium, use low-sodium chicken broth and adjust salt at the end.
- For a citrus-bright contrast, a squeeze of lemon just before serving works well—see my take on citrusy slow-cooked chicken with the Crock Pot creamy lemon chicken breasts for ideas.
Step-by-step instructions
- Place the chicken breasts in a large bowl. Drizzle with olive oil. Sprinkle with Cajun seasoning, garlic powder, onion powder, smoked paprika, salt, and black pepper. Rub the spices into the chicken so it’s evenly coated.
- Heat a large skillet over medium heat. Add a little oil and brown the chicken 2–3 minutes per side—just enough to develop color and seal flavors.
- Transfer the browned chicken to the bottom of the slow cooker. Top with the sliced bell pepper, onion, and minced garlic.
- Pour in the diced tomatoes with their juices and the chicken broth. Cover and cook on low for 4–5 hours or high for 2–3 hours, until chicken reaches 165°F and is very tender.
- Remove the chicken from the crock pot and shred it with two forks. Return the shredded chicken to the crock pot.
- Stir in the heavy cream and grated Parmesan until the cheese melts and the sauce becomes creamy. Taste and adjust seasoning.
- Meanwhile, cook the pasta according to package directions until al dente. Drain well and add the pasta to the slow cooker. Stir to coat the pasta in the sauce.
- Let everything heat together on low for 15–20 minutes so the pasta absorbs some sauce and flavors meld. Garnish with chopped parsley and serve hot.
Tip: If you want the pasta to absorb less sauce for leftovers, cook it a minute less than package directions so it doesn’t get mushy when reheated. For similar slow-cooker finishing techniques, I often refer to methods used in this slow cooker creamy Tuscan garlic chicken.
Best ways to enjoy it
- Plate with a sprinkle of extra Parmesan and chopped parsley for color.
- Serve with garlic bread or crusty baguette to mop up sauce.
- Pair with a simple green salad dressed with lemon vinaigrette to cut the richness.
- For a lighter meal, toss in roasted zucchini or baby spinach at the end to add volume and veggies.
This dish is hearty enough to stand alone but also pairs beautifully with crisp, acidic sides.
Storage and reheating tips
- Refrigerator: Store leftovers in an airtight container for up to 3–4 days.
- Freezer: Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheating: Reheat gently on the stovetop over medium-low, stirring and adding a splash of broth or cream if the sauce has thickened. You can microwave single servings, covered, stirring halfway through to ensure even heating.
- Food safety: Always ensure shredded chicken reaches 165°F when reheated. Do not leave perishable food at room temperature for more than 2 hours.
Pro chef tips
- Browning the chicken isn’t required but adds depth—don’t skip if you have time.
- Use whole-grain or legume-based pasta to boost fiber and protein without changing technique.
- For extra creaminess, stir in a spoonful of cream cheese or mascarpone with the Parmesan.
- If the sauce is too thin after adding cream, remove the lid and cook on high for 10–15 minutes to reduce; too thick, stir in a little reserved pasta water or broth.
- To control heat, start with 1 tablespoon Cajun seasoning; increase or decrease to taste. For smoky heat, add a pinch of cayenne.
For a garlic-forward variation that borrows the comforting richness of other slow-cooker classics, consider elements from this creamy garlic Parmesan chicken technique.
Creative twists
- Protein swap: Use boneless skinless thighs for juicier results and richer flavor.
- Vegetarian option: Replace chicken with firm tofu or roasted portobello slices and use vegetable broth.
- Cheesy bake: Transfer the finished pasta to a baking dish, top with extra Parmesan and breadcrumbs, and broil until golden for a bubbly casserole.
- Spicy Gulf Coast: Add andouille sausage slices during the last hour of cooking for smoky pork flavor.
- Lighter dairy: Substitute half-and-half and a few tablespoons of Greek yogurt (stirred in off heat) instead of heavy cream.
Your questions answered
Q: Can I add the pasta directly to the slow cooker dry?
A: I don’t recommend it. Dry pasta will absorb too much liquid and become gummy. Cook pasta al dente separately, drain, then stir into the crock pot for the best texture.
Q: How long should I cook the chicken to make sure it’s safe?
A: Cook on low 4–5 hours or high 2–3 hours until the chicken’s internal temperature reaches 165°F. A thermometer is the most reliable check.
Q: Can I make this ahead for a party?
A: Yes. Cook everything through step 6, keep the sauce and pasta separate, and assemble just before serving. Reheat the sauce and add pasta at the last minute to keep textures ideal.
Q: What pasta shape works best?
A: Short tubular pastas like penne, rigatoni, or ziti hold the sauce well. Bowties or shells are good alternatives if you prefer.
Q: Is there a gluten-free version?
A: Use gluten-free pasta and ensure your Cajun seasoning and Parmesan are certified gluten-free if needed.
