How this recipe comes together
This is a straightforward slow‑cooker assembly with a quick finishing step:
- Sear and nestle the chicken in the Crock Pot (searing is optional but adds flavor).
- Pour in diced tomatoes with green chiles, chicken broth, and heavy cream.
- Season, then cook low for 6–7 hours until the chicken is fall‑apart tender.
- Thirty minutes before serving, cook penne; shred the chicken directly in the pot.
- Stir in drained pasta and mozzarella so the cheese melts into the sauce.
Expect roughly 6–7 hours hands‑off cooking and 30 minutes active finish time.
What you’ll need
- 1 lb boneless, skinless chicken breasts (sub: thighs for richer flavor)
- 8 oz penne pasta (use gluten‑free penne if needed)
- 1 can (10 oz) diced tomatoes with green chiles
- 1 cup heavy cream (sub: half‑and‑half for lighter, or coconut milk for dairy‑free)
- 1 cup chicken broth
- 2 tbsp Cajun seasoning (adjust to taste)
- 1 cup shredded mozzarella cheese (or pepper jack for extra kick)
- 1 tbsp olive oil
- Salt and pepper to taste
- Chopped parsley for garnish
Tips on ingredients: use a low‑sodium broth if you want tighter control over salt. If you like a smokier profile, smoked paprika or Andouille sausage added at the beginning works nicely — think of it as a nod to other hearty chicken swaps like these Buffalo chicken bombs for spicy inspiration.
Step-by-step instructions
- Pat chicken breasts dry and season lightly with salt and pepper.
- Heat olive oil in a skillet over medium‑high heat. Sear the chicken 1–2 minutes per side until golden (optional but flavorful). Transfer to the Crock Pot.
- Pour the canned diced tomatoes with green chiles, chicken broth, and heavy cream over the chicken.
- Sprinkle Cajun seasoning, and add any extra salt and pepper to taste.
- Cover and cook on LOW for 6–7 hours, or until the chicken reaches an internal temperature of 165°F and is easy to shred.
- About 30 minutes before you want to eat, boil the penne according to package directions until al dente. Drain, reserving a splash of pasta water if you like a looser sauce.
- Shred the cooked chicken directly in the Crock Pot using two forks.
- Stir in the cooked pasta and the shredded mozzarella. If the sauce seems too thick, add a tablespoon or two of the reserved pasta water or extra broth.
- Serve hot, garnished with chopped parsley.
Short, clear action verbs make the finish fast: shred, stir, and serve.
Best ways to enjoy it
Plate this pasta family‑style in a deep bowl so the sauce stays cozy. Pair with:
- A crisp green salad (arugula with lemon vinaigrette cuts richness).
- Garlic bread or crusty rolls to mop up sauce.
- A simple roasted vegetable: broccoli or green beans tossed in olive oil and lemon.
For dessert, something salty‑sweet like these chocolate-covered potato chips makes a playful finish.
Storage and reheating tips
- Refrigerate: let the dish cool to room temperature, then store in an airtight container for 3–4 days.
- Freeze: cool completely, then freeze in a freezer‑safe container for up to 3 months. Note: cream‑based sauces can separate slightly after freezing; vigorous stirring and gentle reheating usually brings them back.
- Reheat: thaw overnight in the fridge if frozen. Reheat on the stovetop over medium‑low, adding a splash of broth or cream and stirring until hot. In the microwave, cover and heat in 1‑minute bursts, stirring each time until the center hits 165°F.
Safety note: always reheat leftovers to an internal temperature of 165°F to ensure food safety.
Helpful cooking tips
- Don’t overcook the pasta: cook to al dente since it will finish in the sauce.
- If you prefer a thicker sauce, remove the lid for the last 30 minutes of slow cooking or stir in a slurry of 1 tsp cornstarch + 1 tbsp cold water.
- Taste before adding salt — the Cajun seasoning and mozzarella already contribute sodium.
- For deeper flavor, toss the chicken with half the Cajun seasoning before searing, and add the remaining seasoning to the Crock Pot.
- To save time, use pre‑shredded mozzarella and pre‑chopped parsley.
Creative twists
- Shrimp swap: add peeled shrimp in the last 20 minutes instead of chicken for a seafood version.
- Low‑carb: replace penne with cooked cauliflower florets or spiralized zucchini (add zucchini toward the end to avoid sogginess).
- Dairy‑free: substitute coconut milk and a dairy‑free cheese; reduce Cajun seasoning slightly to balance coconut’s sweetness.
- Extra heat: stir in 1/4–1/2 tsp cayenne or a chopped jalapeño.
- Smoky sausage: slice smoked Andouille and brown with the chicken for Creole depth.
Common questions
Q: Can I use frozen chicken breasts in the Crock Pot?
A: Yes, but add an hour to the cooking time and ensure the chicken reaches 165°F. For best texture and food safety, thawed chicken is preferred.
Q: What if my sauce is too thin?
A: Remove the lid and let it cook on HIGH for 20–30 minutes to reduce, or stir in a cornstarch slurry (1 tsp cornstarch + 1 tbsp water) and simmer until thickened.
Q: Can I make this ahead and reheat?
A: Absolutely. Store in the fridge for up to 4 days. Reheat gently on the stovetop with a splash of broth or cream to refresh the sauce.
Q: Which pasta works best?
A: Penne is great because it holds sauce, but rigatoni, fusilli, or shells also work. Choose a shape that traps the creamy sauce.
