How this recipe comes together
A quick sear, then low-and-slow cooking creates tender shredded chicken that soaks up the tomato-Cajun broth. Finish with heavy cream and Parmesan to thicken and enrich the sauce. Cook the pasta separately so it stays al dente, then toss everything together for the final meld. Expect about 10–15 minutes active prep, then several hours of set-and-forget cooking.
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
- 1/4 teaspoon black pepper
- 1 bell pepper, thinly 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 (use low-sodium if preferred)
- 1/2 cup heavy cream
- 1/2 cup grated Parmesan cheese
- 8 oz penne pasta (or another short pasta like rigatoni)
- Fresh parsley, chopped for garnish
Substitutions/notes:
- Swap Greek yogurt thinned with a splash of milk for heavy cream to cut calories (add off-heat to avoid curdling).
- Use rotini, farfalle, or gluten-free penne if needed.
- If you prefer a smokier edge, increase smoked paprika by 1/4 teaspoon.

Step-by-step instructions
- Pat the chicken dry. Drizzle with olive oil and rub the Cajun seasoning, garlic powder, onion powder, smoked paprika, salt, and pepper evenly over both sides.
- Heat a skillet over medium-high heat. Sear the chicken 2–3 minutes per side until nicely browned. Browning adds flavor—don’t skip it.
- Transfer the seared chicken to the crock pot. Top with sliced bell pepper, sliced onion, minced garlic, diced tomatoes (with juices), and chicken broth.
- Cook on low for 4–5 hours or on high for 2–3 hours, until the chicken easily shreds with two forks.
- Remove the chicken and shred it with forks. Return shredded chicken to the slow cooker. Stir in the heavy cream and grated Parmesan until the sauce is smooth and combined. Taste and adjust seasoning.
- While the sauce finishes, cook the penne pasta to al dente in salted boiling water. Drain well.
- Add the cooked pasta to the slow cooker and stir to coat. Heat together on low for 15–20 minutes so the pasta soaks up the sauce. If the sauce looks too thin, remove the lid and let it reduce for 10 minutes, or stir in 1–2 tablespoons of grated Parmesan to thicken.
- Serve hot with chopped parsley on top.
Best ways to enjoy it
Serve this creamy Cajun pasta with:
- A crisp green salad (arugula with lemon vinaigrette cuts the richness).
- Roasted vegetables—broccoli or asparagus tossed in olive oil and lemon.
- Garlic bread or crusty rolls to mop up the sauce.
For plating, nest a portion of pasta in a warm shallow bowl, sprinkle extra Parmesan and chopped parsley, and finish with a lemon wedge if you like a bright contrast.
Storage and reheating tips
- Refrigeration: Cool leftovers to room temperature and refrigerate within 2 hours. Store in an airtight container for 3–4 days.
- Freezing: Freeze in airtight containers for up to 2–3 months. Note that cream-based sauces can change texture slightly after freezing; stirring in a splash of cream or milk when reheating helps restore creaminess.
- Reheating: Gently reheat on the stove over low heat, stirring often. Add a splash of chicken broth, water, or cream if the sauce has thickened. Microwaving works—heat in 60-second bursts, stirring in between to ensure even warming.
- Food safety: Always reheat to an internal temperature of 165°F (74°C) before eating.
Pro chef tips
- Sear for flavor: Browning the chicken adds Maillard flavor that lifts the whole dish. It’s worth the extra few minutes.
- Keep pasta al dente: Finish the pasta slightly firmer than you’d normally eat—it will soften as it sits in the sauce.
- Control the spice: If you’re serving kids, start with 1/2 tablespoon Cajun seasoning and add more to plates later.
- For a thicker sauce: Stir in 1–2 tablespoons of grated Parmesan off the heat, or make a slurry of 1 tsp cornstarch + 1 tbsp cold water and stir into the sauce before adding pasta.
- Avoid overcooking dairy: Add cream and cheese near the end of cooking to prevent graininess.
Creative twists
- Shrimp swap: In the last 30 minutes of cooking, add peeled shrimp instead of chicken for a seafood twist—shrimp cooks quickly, so watch it.
- Sausage and chicken combo: Use sliced smoked sausage for extra depth. Brown it first with the chicken.
- Vegetarian: Replace chicken with firm tofu or roasted cauliflower and use vegetable broth. Add mushrooms for meatiness.
- Extra-creamy: Stir in 4 oz cream cheese at the same time as the heavy cream for a tangy, ultra-silky sauce.
- Low-carb: Serve over spiralized zucchini or shirataki noodles; add the pasta substitute just before serving so it doesn’t get watery.
Common questions
Q: Can I use frozen chicken breasts in the slow cooker?
A: You can, but it’s safer and gives better texture to thaw them first. If you must use frozen, increase the cooking time and ensure the internal temperature reaches 165°F (74°C).
Q: Is it OK to cook the pasta in the slow cooker instead of separately?
A: You can, but pasta tends to absorb too much liquid and becomes mushy if cooked long in the slow cooker. Cooking pasta separately and adding it at the end keeps it al dente.
Q: How spicy is this dish, and can I tone it down?
A: The recipe has a noticeable Cajun kick, but it’s not overwhelming. Reduce the Cajun seasoning by half to tone down heat, or use mild paprika instead of smoked paprika.
Q: Can I make this ahead for a party?
A: Yes. Cook through step 5, cool, refrigerate, and reheat later. Add cream and Parmesan when reheating, then toss with freshly cooked pasta just before serving.
Q: Will the cream separate if I reheat leftovers?
A: If reheated gently and stirred often, the cream should hold up. If the sauce looks broken, whisk in a little extra cream or a pat of butter off-heat to smooth it.
