How this recipe comes together
Start by prepping the chicken and veggies. Everything goes into the crock pot with cream and broth so the flavors meld slowly. While the chicken simmers and soaks up the seasoning, you cook the penne on the stovetop for perfect al dente texture. Add the pasta to the crock pot at the end so it soaks up the sauce without turning mushy. The whole process is straightforward: prep, slow-cook, boil pasta, combine, garnish, serve.
What you’ll need
- 1 pound chicken breast, diced into bite-sized pieces (boneless, skinless)
- 1 tablespoon Cajun seasoning (adjust to taste)
- 1 cup heavy cream
- 2 cups penne pasta (uncooked)
- 1 cup chicken broth
- 1 bell pepper, chopped (any color)
- 1 onion, chopped (yellow or white)
- 2 cloves garlic, minced
- Salt and pepper to taste
- Parmesan cheese, freshly grated, for serving
- Fresh parsley, chopped, for garnish
Substitutions and notes:
- Heavy cream: use half-and-half plus a tablespoon of cornstarch if you want a lighter sauce (mix cornstarch with a little cold liquid first).
- Pasta: penne works best because its ridges catch the sauce, but rigatoni or ziti are good alternatives.
- Spice: use smoked paprika and cayenne for a smokier kick, or reduce the Cajun seasoning for kids.

Step-by-step instructions
- Prep: Dice the chicken into bite-sized pieces, chop the bell pepper and onion, and mince the garlic.
- Build in the crock pot: Place the diced chicken in the slow cooker. Sprinkle the Cajun seasoning evenly over the chicken. Add the heavy cream, chicken broth, chopped bell pepper, chopped onion, and minced garlic. Stir gently so the chicken and vegetables are coated. Taste the liquid for baseline seasoning — it will concentrate as it cooks.
- Slow-cook: Cover and cook on low for 6–7 hours or on high for 3–4 hours, until the chicken is very tender. For safety, ensure chicken reaches an internal temperature of 165°F (74°C).
- Cook the pasta: About 30 minutes before serving, bring a large pot of salted water to a boil. Cook the penne until just al dente (usually 1–2 minutes less than the package time). Drain and reserve a cup of pasta water.
- Combine: Add the drained penne to the crock pot and stir gently. If the sauce is too thick, loosen with a few tablespoons of the reserved pasta water or extra chicken broth. Taste and season with salt and pepper as needed.
- Serve: Spoon into bowls and top with freshly grated Parmesan and chopped parsley.
Timing tip: add the pasta only at the end so it stays firm; cooking it inside the slow cooker will usually make it overcooked.
Best ways to enjoy it
- Plate: mound pasta in a shallow bowl and spoon extra sauce and chicken over the top, then grate Parmesan and sprinkle parsley.
- Sides: a crisp green salad, roasted broccoli, or garlic bread balance the richness.
- Drinks: pair with a bright, unoaked Chardonnay, a citrusy lager, or iced tea for non-alcoholic pairing.
- Garnish ideas: red pepper flakes for heat, lemon zest for brightness, or a drizzle of olive oil for sheen.
Storage and reheating tips
- Refrigerator: Cool to room temperature (no longer than 2 hours out) then store in an airtight container up to 3–4 days.
- Freezer: Portion into freezer-safe containers and freeze for up to 2 months. Texture will change slightly; thaw overnight in the fridge before reheating.
- Reheating: Warm gently on the stovetop over low heat, stirring and adding a splash of chicken broth or cream if the sauce has thickened. Microwave in short intervals, stirring between bursts, until hot. Always reheat to at least 165°F (74°C) for safety.
Helpful cooking tips
- Browning chicken first? Optional. Searing diced chicken quickly in a hot skillet adds caramelized flavor, but it’s fine to skip for a true dump-and-go approach.
- Adjusting thickness: Heavy cream will thicken as it cools. If the sauce becomes too thick after refrigeration, stir in warm broth or a little milk when reheating.
- Salt carefully: Broth and Parmesan add salt; season gradually and taste near the end.
- Spice control: Start with 1 tablespoon of Cajun seasoning; some blends are saltier or spicier than others. Add more at the end if needed.
- Shortcuts: Use rotisserie chicken shredded in the last 30 minutes to cut slow-cook time.
Creative twists
- Cajun shrimp pasta: Swap the chicken for peeled shrimp; add shrimp in the last 20–30 minutes on low so they don’t overcook.
- Andouille sausage: Slice and brown sausage, then add to the crock pot for smoky depth.
- Vegetarian version: Replace chicken with firm tofu or roasted chickpeas and use vegetable broth. Add mushrooms for meaty texture.
- Extra veg: Fold in spinach or kale at the end until wilted, or add corn and zucchini during the last hour for variety.
- Baked finish: Transfer to a baking dish, top with extra cheese, and broil briefly for a gratin-style crust.
Common questions
Q: Can I use frozen chicken?
A: It’s safest to use thawed chicken so the slow cooker brings it to a safe temperature more evenly. If you must use frozen, increase cooking time and be sure the internal temperature reaches 165°F (74°C); however, texture may be less consistent.
Q: Can I cook the pasta in the slow cooker so there’s less cleanup?
A: I don’t recommend it. Pasta added raw will absorb too much liquid and usually becomes mushy. Cook pasta separately to al dente and add it at the end so the texture stays pleasant.
Q: What can I substitute for heavy cream?
A: Half-and-half thinned slightly or whole milk thickened with a slurry of 1–2 teaspoons cornstarch can work. Coconut cream is an option for dairy-free versions but will change the flavor. Expect some differences in richness and mouthfeel.
Q: How spicy is this dish and how can I adjust it?
A: Spice level depends on your Cajun seasoning. To reduce heat, use half the seasoning and add more at the end. To boost heat, add cayenne or chopped hot peppers.
Q: Can I make this ahead for a party?
A: Yes — cook everything except the pasta up to 24 hours ahead, refrigerate, then rewarm and stir in freshly cooked pasta before serving.
