Step‑by‑Step Instructions for Spicy Rattlesnake Pasta
Step 1: Prep Ingredients
Begin by cooking the penne pasta in a large pot of salted boiling water according to package instructions, usually about 8 to 10 minutes until al dente. Drain the pasta and set it aside, reserving a cup of the starchy cooking water to help adjust the sauce consistency later if needed.
Step 2: Sauté Protein
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Once hot, add your choice of chicken or shrimp and cook for about 4-6 minutes, turning occasionally, until the protein is cooked through and reaches an internal temperature of 165°F. Remove from the skillet and set aside.
Step 3: Make Sauce
In the same skillet, add another tablespoon of olive oil and reduce the heat to medium. Add 3 minced garlic cloves and sauté for about 30 seconds until fragrant and golden, being careful not to burn the garlic. Then, pour in 1 cup of heavy cream and stir in 2 tablespoons of Cajun seasoning and a pinch of red pepper flakes, heating until the sauce just begins to simmer.
Step 4: Combine
Return the cooked chicken or shrimp to the skillet and add the drained penne. Toss everything together gently, allowing the pasta to soak up the creamy Cajun sauce for about 2-3 minutes, ensuring even coating. If the sauce appears too thick, stir in a little reserved pasta water until you reach your desired consistency.
Step 5: Serve
Once everything is well-combined and heated through, remove the skillet from the heat. Serve your Spicy Rattlesnake Pasta immediately, garnishing with freshly grated Parmesan cheese, if desired. Pair it with some garlic bread or a crisp salad for a delightful meal.
Expert Tips for Rattlesnake Pasta
- Garlic Timing: Always sauté garlic until it’s lightly golden to prevent bitterness. This ensures your sauce has all the rich flavor!
- Creamy Texture: If your sauce thickens too much while cooking, don’t hesitate to add a splash of reserved pasta water for a smoother consistency.
- Seasoning Adjustment: Start with a smaller amount of Cajun seasoning, especially if you’re unsure about heat levels. You can always add more to intensify the flavors.
- Protein Choice: If using chicken or shrimp, make sure they’re fully cooked to a safe temperature (165°F). If going vegetarian, sauté tofu until it’s crisp for added texture!
- Prepping Ahead: If you plan on making the Rattlesnake Pasta ahead of time, keep the pasta separate from the sauce to maintain its texture. Combine just before serving for the best experience!

When you’re ready to serve, reheat the sauce gently, toss in the cooked protein and pasta, and simmer until everything is warmed through. This way, you’ll enjoy restaurant-quality flavors with minimal effort!
