What You’ll Need
To create this spicy masterpiece, you will need a pound of penne pasta and boneless skinless chicken breast seasoned with a bold Cajun blend. The sauce is built on a foundation of butter, flour, and chicken stock, enriched with whole milk and heavy cream. A vibrant trio of red bell pepper, green bell pepper, and red onion provides color and crunch, while a generous amount of roasted garlic and Parmesan cheese provides the signature savory depth.
Ingredient Notes
- Roasted Garlic – Using a full head of roasted garlic is the secret to this recipe. Roasting transforms the garlic from sharp and pungent to sweet, buttery, and mellow, providing a complex undertone to the spicy sauce.
- Cajun Seasoning – This provides the primary heat and smoky flavor. Be sure to use a high-quality blend, or adjust the amount to your preferred spice tolerance.
- Penne Pasta – The ridges and hollow center of penne are perfect for “trapping” the thick, creamy sauce, ensuring flavor in every bite.
- Heavy Cream and Parmesan – These ingredients provide the luxurious Rattlesnake finish, creating a thick sauce that clings perfectly to the pasta and vegetables.
- Bell Peppers and Red Onion – Slicing these into uniform 1/4 inch strips ensures they sauté evenly and provide a consistent texture throughout the dish.
Add-ins and Substitutions
- Seafood Twist: Replace the chicken with large shrimp for a “Rattlesnake Shrimp” version of the dish.
- Extra Heat: For an even bigger bite, add sliced jalapeños or a pinch of red pepper flakes to the vegetable sauté.
- Mushroom Addition: Sliced cremini or button mushrooms sautéed with the peppers add a lovely earthy depth to the creamy sauce.
How to Make Spicy Creamy Rattlesnake Pasta
The success of this dish lies in the layering of flavors searing the chicken first to develop a crust, then using the same pan for the vegetables and the sauce base.
Start by cooking your penne for 2 minutes less than the al dente package instructions; this ensures the pasta finishes cooking in the sauce without becoming mushy. While the pasta cooks, toss your cubed chicken in Cajun seasoning and sear it in butter until fully cooked, then set it aside. In the same skillet, sauté your peppers and onions until they begin to soften.
The sauce begins with a roux melting butter and whisking in flour to create a thickener. Gradually add the chicken stock and milk, followed by the coarsely chopped roasted garlic. Once the sauce has simmered and thickened, stir in the Parmesan cheese and heavy cream until perfectly smooth. Finally, fold the chicken, vegetables, and under-cooked pasta back into the sauce, heating everything together for a few minutes until the sauce is glossy and the pasta is tender.
Pro Tip: Under-cooking the pasta by 2 minutes is a crucial step. By finishing the pasta directly in the sauce for the final few minutes of cooking, the starch from the pasta helps the sauce adhere perfectly, and the penne absorbs the flavor of the cream and Cajun spices rather than just being coated by them.
Recipe Tips
- Roux Management: When cooking the flour and butter, keep it moving with a whisk. You want to cook off the raw flour taste (3–4 minutes) without letting it turn dark brown or burn.
- Roast the Garlic Ahead: You can roast your garlic a day in advance to save time during the actual cooking process.
- Check the Consistency: If the sauce becomes too thick while simmering, simply add a small splash of chicken stock or pasta water to loosen it up to your desired consistency.
- Wait for the Simmer: Ensure the sauce comes to a gentle simmer before adding the Parmesan and cream; this helps the cheese melt smoothly without clumping.
FAQs
How spicy is this pasta? The spice level depends largely on your brand of Cajun seasoning. As written, it is medium-spicy. If you are sensitive to heat, start with half the amount of seasoning and add more to taste.
Can I use a different pasta shape? Yes! While penne is traditional for this style of dish, bow tie (farfalle) or rigatoni are excellent substitutes that also hold onto thick sauces very well.
Can I use pre-minced garlic instead of roasted? You can, but the flavor will be significantly sharper. If you skip the roasting step, reduce the amount of garlic to 1 tablespoon of minced garlic to prevent it from overwhelming the dish.
Serving Suggestions
- Garlic Bread: A side of buttery, toasted garlic bread is perfect for swiping up any extra creamy sauce left on the plate.
- Garden Salad: A crisp, light green salad with a lemon vinaigrette provides a refreshing contrast to the rich, spicy pasta.
- Green Onions: Don’t skip the chopped green onion garnish; the fresh, oniony bite cuts through the richness of the heavy cream and Parmesan.
Make This Recipe in Advance
This pasta is best enjoyed fresh, but you can prepare the components ahead of time. The chicken and vegetables can be sautéed and stored in the fridge for up to 2 days. The roasted garlic can be prepared a week in advance. When reheating leftovers, add a splash of milk or water to the pan to help the cream sauce regain its smooth consistency, as it will naturally thicken significantly when cold.
