How this recipe comes together
A quick overview before you get cooking: pat and spice the chicken, sear it briefly for extra flavor, then slow-cook with peppers, onions, garlic, tomatoes, and broth until tender. Shred the chicken, stir in cream and Parmesan for a silky sauce, then fold in separately cooked penne so it stays al dente.

Timing snapshot:
- Active hands-on time: ~15–20 minutes (searing, prepping, final stir)
- Slow-cooker time: 2–5 hours (depending on low vs. high)
- Final combine and warm-through: 15–20 minutes
What you’ll need
- 1 lb boneless, skinless chicken breasts
- 2 tablespoons olive oil (for rubbing/searing)
- 1 tablespoon Cajun seasoning (use your favorite blend)
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon smoked paprika (adds depth — optional)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 bell pepper, thinly sliced (red or green)
- 1 small onion, thinly sliced
- 3 cloves garlic, minced (or 1 tsp jarred)
- 1 (14.5 oz) can diced tomatoes, with juices
- 1 cup chicken broth (low-sodium if preferred)
- 1/2 cup heavy cream
- 1/2 cup grated Parmesan cheese (freshly grated for best melt)
- 8 oz penne pasta
- Fresh parsley, chopped for garnish
Substitutions and notes:
- Make it lighter: swap half-and-half for heavy cream, but sauce will be thinner.
- Gluten-free: use GF penne.
- Dairy-free: replace cream with full-fat coconut milk and use nutritional yeast instead of Parmesan (flavor will change).
- Spice level: increase Cajun seasoning or add 1/4–1/2 teaspoon cayenne for more heat.
Step-by-step instructions
- Pat the chicken dry with paper towels. Rub with olive oil, then evenly coat with Cajun seasoning, garlic powder, onion powder, smoked paprika, salt, and pepper.
- Heat a skillet over medium-high heat. Add a little oil and sear the breasts 2–3 minutes per side until browned — you’re not cooking through, just building flavor and color.
- Transfer the seared chicken to the crock pot. Add bell pepper, onion, minced garlic, diced tomatoes (with juices), and chicken broth. Stir once to distribute.
- Cook on low for 4–5 hours or on high for 2–3 hours, until the chicken is tender and shreds easily.
- Remove the chicken to a cutting board and shred with two forks, then return the shredded chicken to the slow cooker. Stir in the heavy cream and grated Parmesan until the sauce is smooth and slightly thickened. Taste and adjust seasoning.
- Meanwhile, cook the penne pasta in salted boiling water until al dente (follow package directions). Drain well.
- Add the drained pasta to the slow cooker and stir to combine. Cover and cook on low for an additional 15–20 minutes so the pasta absorbs some sauce and everything warms through. If the sauce is too thick, loosen with a splash of pasta cooking water or extra broth.
- Serve hot, sprinkled with chopped parsley.
Best ways to enjoy it
- Serve with a simple green salad (vinaigrette cuts the richness) or garlic-roasted broccoli for color and crunch.
- For bread lovers, warm crusty French bread or garlic knots soak up the creamy sauce beautifully.
- Wine pairings: a chilled Sauvignon Blanc or a light Pinot Noir balances the spice without overpowering the dish.
- For a family-style presentation, place the slow cooker on the table and let guests spoon pasta onto plates, garnishing with extra Parmesan and parsley.
Storage and reheating tips
- Fridge: Store leftovers in an airtight container for up to 3–4 days. Cool to room temperature (within 2 hours) before refrigerating.
- Freezer: Freeze in a freezer-safe container for up to 2 months. Note that the pasta texture may soften after freezing; freeze the sauce and shredded chicken separately from fresh-cooked pasta if you prefer better texture on thaw/reheat.
- Reheat: Slow and gentle is best. Rewarm on the stove over low heat, stirring in a splash of broth or cream to loosen the sauce. Microwave in 30–45 second bursts, stirring between, until heated through. If frozen, thaw overnight in the refrigerator before reheating.
- Food safety: Do not leave cooked food at room temperature for more than 2 hours. Reheat leftovers to at least 165°F (74°C) before serving.
Helpful cooking tips
- Searing is optional but recommended — it adds complex flavor through caramelization.
- Use freshly grated Parmesan for a creamier, silkier finish; pre-grated cheese can be grainy due to anti-caking agents.
- If you like more sauce, reduce the pasta to 6–7 oz or add an extra 1/4–1/2 cup heavy cream.
- To keep pasta from getting mushy, cook penne until very slightly under al dente if you plan to finish it in the slow cooker.
- Taste before serving; slow-cooker dishes often need a final salt/acid adjustment (a squeeze of lemon juice brightens the flavors).
Creative twists
- Shrimp swap: substitute 1 lb peeled shrimp, add during the last 30–40 minutes on low so they don’t overcook.
- Andouille sausage: slice and brown 8 oz and add with the vegetables for a smoky, meaty boost.
- Vegetarian version: replace chicken with roasted cauliflower or cubed extra-firm tofu and use vegetable broth.
- Extra-creamy: fold in 4 oz cream cheese at the same time as the heavy cream for a richer texture.
- Heat boosters: fold in sliced pickled jalapeños or a few dashes of hot sauce at the end for extra spice.
Common questions
Q: Can I cook the pasta directly in the slow cooker?
A: You can, but it’s tricky to get perfect texture. Pasta cooked in the slow cooker often becomes overcooked and soggy. For best results, cook pasta separately al dente and add it at the end.
Q: Can I use frozen chicken breasts in the crock pot?
A: You can, but thawed chicken is preferable for even cooking and food safety. If using frozen, increase cook time and ensure the internal temperature reaches 165°F. Note that slow-cooking from frozen can keep meat too long in the bacterial danger zone, so thawing is safer.
Q: How long does this take from start to finish?
A: Hands-on time is about 15–20 minutes (prep, searing, final stirring). Total time depends on slow-cooker setting: 2–3 hours on high or 4–5 hours on low, plus 15–20 minutes to cook pasta and finish.
Q: Can I make this ahead for a party?
A: Yes — prepare up to the point of adding pasta, refrigerate, then reheat and stir in freshly cooked pasta before serving. If transporting, keep sauce warm in the slow cooker on the low setting.
Q: Is this dish freezer-friendly?
A: The sauce and shredded chicken freeze well; freeze without the pasta or freeze pasta separately to preserve texture.
