“A total weekday win — the house smelled incredible, the chicken shredded perfectly, and everyone went back for seconds.” — a reader review
Perfect for busy weeknights, casual dinner parties, or whenever you want a cozy, comforting pasta with some Southern heat.
Step-by-step overview
This is a hands-off recipe with a few short active steps:
- Season and quickly sear the chicken to build flavor.
- Layer the seared chicken with peppers, onions, tomatoes, and broth in the slow cooker.
- Slow-cook until the chicken is fall-apart tender, then shred it.
- Stir in heavy cream and Parmesan, then toss with separately cooked pasta so the noodles stay al dente.
Prep time is mostly seasoning and searing (about 10–15 minutes). Slow-cook time is 2–5 hours depending on the setting. Final assembly takes another 15–20 minutes.
What you’ll need
- 1 lb boneless, skinless chicken breasts
- 2 tablespoons olive oil (for searing)
- 1 tablespoon Cajun seasoning (adjust to taste)
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon salt (or to taste)
- 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 (low-sodium works well)
- 1/2 cup heavy cream (substitute: half-and-half for lighter, or full-fat coconut milk for dairy-free)
- 1/2 cup grated Parmesan cheese (freshly grated melts best)
- 8 oz penne pasta (or pasta of choice; gluten-free pasta works too)
- Fresh parsley, chopped for garnish

Step-by-step instructions
- Pat the chicken dry and rub with olive oil. Combine Cajun seasoning, garlic powder, onion powder, smoked paprika, salt, and pepper; rub evenly over the chicken.
- Heat a skillet over medium heat. Sear the chicken 2–3 minutes per side until lightly golden. You don’t need to cook through — searing just adds flavor.
- Place the seared chicken in the Crock Pot. Top with sliced bell pepper, onion, minced garlic, diced tomatoes (with juices), and chicken broth.
- Cover and slow-cook on LOW for 4–5 hours or on HIGH for 2–3 hours, until the chicken registers 165°F and is tender enough to shred.
- Remove the chicken, shred with two forks, and return it to the slow cooker. Stir in heavy cream and grated Parmesan until the sauce is smooth and warmed through. Taste and adjust seasoning.
- Meanwhile, cook the pasta according to package instructions until al dente. Drain well — you want the pasta dry so the sauce clings instead of thinning out.
- Add the cooked pasta to the Crock Pot and stir to coat. Let everything warm together for 15–20 minutes so the noodles absorb some sauce and flavors meld.
- Serve hot, garnished with chopped parsley.
Quick safety tip: always confirm the thickest part of the chicken reaches 165°F to ensure it’s safe to eat.
Best ways to enjoy it
- Serve with a crisp green salad (simple vinaigrette cuts the creaminess nicely).
- Toasted garlic bread or cheesy focaccia is great for sopping up sauce.
- For a lighter pairing, serve with roasted veggies like broccoli or green beans.
- To plate for guests: nestle pasta in shallow bowls and finish with an extra sprinkle of Parmesan and a drizzle of olive oil.
Storage and reheating tips
- Refrigerate within 2 hours of cooking in an airtight container. Keeps 3–4 days in the fridge.
- Freeze in a freezer-safe container for up to 2–3 months. Portion before freezing for easier reheating.
- Reheat from the fridge on the stovetop over low heat, stirring in a splash of broth or cream to loosen sauce. From frozen, thaw overnight in the fridge first.
- In the microwave, reheat in 30–60 second bursts, stirring between intervals to heat evenly. Always reheat to an internal temperature of 165°F.
Helpful cooking tips
- Don’t overcook the pasta; al dente will prevent mushy leftovers. Toss pasta with a teaspoon of oil after draining if you’re waiting to add it.
- Searing the chicken is optional but recommended — it deepens flavor. If short on time, skip searing and add directly to the slow cooker.
- If the sauce seems thin after adding pasta, cook with the lid off for 10–15 minutes to reduce and thicken.
- For extra creaminess, stir in an extra tablespoon of butter when adding Parmesan.
- Use freshly grated Parmesan (not pre-grated) for better melting and flavor.
Recipe variations
- Dairy-free: swap heavy cream for full-fat coconut milk and use dairy-free Parmesan alternative.
- Protein swap: use boneless skinless thighs for richer flavor and more forgiving cooking times.
- Low-carb: serve over sautéed zucchini noodles or cauliflower gnocchi.
- Heat level: increase Cajun seasoning or add a pinch of cayenne; reduce for kid-friendly versions.
- Make it cheesy: stir in 1/2 cup shredded cheddar with the Parmesan for a Southern-style twist.
Common questions
Q: Can I skip searing the chicken?
A: Yes — searing adds flavor and color but isn’t required. If you skip it, you may want to increase seasoning slightly.
Q: Will the pasta get mushy if I cook it in the slow cooker?
A: Pasta cooked directly in a slow cooker often becomes too soft. Cooking pasta separately keeps it al dente and preserves the sauce’s texture.
Q: Can I use cream cheese instead of heavy cream?
A: You can, but mix cream cheese with a splash of milk or broth to loosen it before adding; otherwise the sauce may be too thick or form clumps.
Q: How can I make this spicier without changing the recipe much?
A: Add a teaspoon of cayenne, a few dashes of hot sauce, or a chopped jalapeño with the peppers. Taste and adjust gradually.
Q: Is it safe to freeze leftovers with pasta?
A: It’s better to freeze the sauce and chicken separately from the pasta. Pasta can become mushy when frozen and reheated. If you must freeze together, expect softer texture after thawing.
