How To Make One Pot Creamy Cajun Ranch Chicken Pasta
- Season the Chicken:
- Toss your chicken cubes with Cajun seasoning ensuring each piece is thoroughly coated. This step is crucial as it builds the foundation of flavor. Make sure to use 3 teaspoons of your seasoning here, saving the remaining half teaspoon for the sauce later.
- Sear the Chicken:
- Melt butter in your skillet over medium heat until it begins to foam slightly. Add the seasoned chicken in a single layer ensuring pieces aren't overcrowded. Cook until each side develops a golden brown crust and chicken reaches 165°F internally. This takes about 5 to 7 minutes. The brown bits that form on the pan bottom are flavor gold so don't worry about them.
- Build the Sauce Base:
- Once chicken is removed, pour in chicken broth and heavy cream. Scrape the bottom of the pan vigorously to incorporate all those browned bits into your liquid. This deglazing process is essential for developing complex flavor in your sauce.
- Cook the Pasta:
- Add your dry penne directly to the liquid, allowing it to cook in the flavorful broth. Maintain a gentle simmer, not a rolling boil, to prevent the cream from separating. Stir frequently to ensure even cooking and prevent sticking. The pasta will absorb much of the liquid, becoming tender in about 8 to 10 minutes.
- Finish the Sauce:
- Incorporate ranch dressing and remaining Cajun seasoning. This final seasoning layer adds complexity and balances the heat with creaminess. The sauce should coat the back of a spoon but still be fluid enough to surround the pasta.
- Add the Cheese:
- Remove from heat before adding cheeses to prevent them from becoming stringy or separating. The residual heat will melt them perfectly, creating a silky smooth sauce that clings to every piece of pasta.
- Reincorporate Chicken:
- Gently fold the cooked chicken back into the pasta, allowing it to rewarm in the hot sauce. Each piece should be coated in the creamy mixture ensuring flavor in every bite.

The ranch dressing is truly the secret ingredient here. I discovered this combination accidentally when I ran out of my usual cream cheese and grabbed ranch from the fridge in desperation. My family declared it was the best version I'd ever made, and now I wouldn't dream of making it any other way.
Make Ahead Options
This pasta reheats beautifully, making it perfect for meal prep. Cook the entire dish, cool completely, then portion into airtight containers. It keeps well for up to 4 days in the refrigerator. When reheating, add a splash of milk or cream to revive the sauce as it will thicken considerably in the fridge. Microwave on medium power, stirring occasionally to ensure even heating throughout.
Ingredient Substitutions
If you need to make adjustments to this recipe, there are several options. Chicken thighs can replace chicken breasts for more richness and moisture. Any short pasta shape works well here, including rotini, farfalle, or shells. For a lighter version, substitute half and half for heavy cream though the sauce will be slightly less rich. Vegetarians can skip the chicken entirely and use vegetable broth instead, doubling the cheese for protein or adding sautéed mushrooms for a meaty texture.

Spice Adjustments
Cajun seasoning varies widely in heat level between brands. If cooking for those sensitive to spice, start with half the recommended amount and adjust upward after tasting. For spice lovers, add a diced jalapeño when sautéing the chicken or incorporate a dash of hot sauce into the finished dish. The creamy elements help temper the heat, making this highly customizable to your preference. Remember you can always add more spice, but you cannot take it away; so start conservatively.
Serving Suggestions
This hearty pasta shines as a standalone meal but pairs wonderfully with a simple side salad dressed with lemon vinaigrette to cut through the richness. Garlic bread is perfect for sopping up any remaining sauce. For a dinner party presentation, transfer to a large shallow bowl, garnish with additional fresh herbs, cracked black pepper, and a drizzle of good olive oil. Serve with a crisp white wine like Pinot Grigio or Sauvignon Blanc to complement the creamy, spicy flavors.
