This recipe hits several home-cooking sweet spots: it’s low-effort, high-flavor, and easy to scale for family dinners or meal prep. The Cajun seasoning gives a warm, smoky kick while the heavy cream and Parmesan smooth everything into a luxurious sauce.

"A little spice, big comfort — this is the kind of weeknight dish everyone asks for seconds of."
Made for busy weeknights, casual dinner parties, or when you want pasta that feels chef-made without the fuss.
Step-by-step overview
- Season and sear the chicken so it develops color and deeper flavor.
- Layer the vegetables, tomatoes, and broth in the slow cooker over the chicken.
- Slow-cook until the chicken is tender, shred it, then enrich the sauce with cream and Parmesan.
- Cook pasta separately to al dente, then combine with the sauce in the slow cooker to finish and meld flavors.
This approach ensures the pasta texture is perfect and the sauce stays creamy.
What you’ll need
- 1 lb boneless, skinless chicken breasts
- 2 tablespoons olive oil (for rubbing and 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
- 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 (substitute: half-and-half for lighter sauce, but cook a bit longer)
- 1/2 cup grated Parmesan cheese (freshly grated melts best)
- 8 oz penne pasta (or pasta of choice; gluten-free works too)
- Fresh parsley, chopped for garnish
Ingredient notes: use low-sodium broth if you want tighter salt control. If you prefer more heat, add a pinch of cayenne or hot sauce at the end.
How to prepare it
- Pat the chicken dry and place it in a large bowl. Drizzle with olive oil. Sprinkle the Cajun seasoning, garlic powder, onion powder, smoked paprika, salt, and pepper. Rub the spices into the chicken so each piece is well coated.
- Heat a large skillet over medium heat. Add a little oil if needed. Sear the chicken 2 to 3 minutes per side until lightly browned. Browning adds flavor but does not need to be fully cooked through.
- Transfer the seared chicken to the bottom of the slow cooker. Scatter the sliced bell pepper, sliced onion, and minced garlic evenly over the chicken.
- Pour the diced tomatoes with their juices and the chicken broth into the slow cooker. Do not stir; leave the layers as they are.
- Cover and cook on low for 4 to 5 hours or on high for 2 to 3 hours, until the chicken reaches 165°F and is easy to shred.
- Remove the chicken and shred it with two forks, then return the shredded meat to the slow cooker. Stir to combine.
- Stir in the heavy cream and grated Parmesan until the cheese melts and the sauce is silky. Taste and adjust seasoning.
- Cook the pasta according to package directions until al dente. Drain thoroughly. Add the drained pasta to the slow cooker and stir to coat in the sauce.
- Let the combined pasta and sauce heat on low for 15 to 20 minutes so flavors meld. Serve garnished with fresh parsley.

Best ways to enjoy it
Serve this pasta straight from the slow cooker for a cozy family-style meal. For plating, twirl a portion of penne into a shallow bowl, spoon extra sauce over the top, and finish with a sprinkle of parsley and extra Parmesan. Pair with a crisp green salad or roasted vegetables to cut through the richness. For a related twist that leans more garlicky and creamy, you might also enjoy this creamy chicken garlic parmesan pasta as an alternate weeknight option.
Storage and reheating tips
- Refrigerate leftovers within two hours of cooking. Store in an airtight container for up to 3 to 4 days.
- To reheat on the stove: add a splash of chicken broth or cream to loosen the sauce, then warm gently over low heat until heated through. Stir frequently.
- To reheat in the microwave: cover and heat in 30- to 60-second intervals, stirring between bursts and adding a little liquid if the sauce has thickened.
- To freeze: cool completely, portion into freezer-safe containers, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Food safety note: ensure reheated chicken reaches 165°F before serving.
Helpful cooking tips
- Searing is optional but recommended. It adds caramelized flavor and a better final sauce.
- If short on time, use leftover or rotisserie-style chicken and skip slow cooking; combine shredded chicken with the tomato-broth base in a saucepan and simmer 15 minutes before finishing with cream and cheese.
- Use freshly grated Parmesan for smoother melting. Pre-grated cheese can sometimes be chalky.
- Avoid overcooking the pasta in the slow cooker; cooking it separately prevents gummy texture.
- Taste the sauce after adding cheese and cream; Parmesan adds salt, so adjust gently.
Recipe variations
- Make it lighter: swap heavy cream for half-and-half and reduce the Parmesan slightly.
- Protein swaps: use boneless chicken thighs for more fat and richness, or shredded rotisserie chicken as a shortcut.
- Make it vegetarian: replace chicken with a mix of hearty mushrooms and chickpeas and use vegetable broth.
- Add more heat: increase Cajun seasoning or add crushed red pepper flakes and a pinch of cayenne.
- Cheese swaps: try Asiago or Pecorino Romano if you want a sharper finish.
Common questions
How long does this take from start to finish?
Hands-on time is about 20 minutes for searing and prep. Slow-cook time is 2 to 3 hours on high or 4 to 5 hours on low. Add 15 to 25 minutes to cook the pasta and finish the dish.
Can I skip searing the chicken?
Yes, you can skip searing if you’re short on time. The chicken will still cook and shred fine in the slow cooker, but searing adds depth of flavor and a nicer sauce.
Can I cook the pasta in the slow cooker instead of separately?
I don’t recommend it. Pasta cooked in the slow cooker often becomes overcooked and gummy. Cooking pasta separately to al dente and then folding it into the sauce gives the best texture.
Can I use frozen chicken breasts?
You can, but increase the cooking time and ensure the internal temperature reaches 165°F. Using frozen chicken may also release extra liquid, which can thin the sauce; adjust by reducing broth slightly or simmering uncovered at the end.
Is this safe to freeze and reheat?
Yes. Freeze in airtight containers for up to 3 months. Thaw overnight in the fridge and reheat gently on the stove with a splash of broth or cream.
