How to Make Spicy Rattlesnake Pasta
Step 1: Cook the Pasta
Start by boiling your penne in salted water until it’s al dente—about one minute less than package directions suggest. This way, it’ll hold up nicely when mixed with the sauce! Don’t forget to reserve that precious half cup of pasta water before draining; we’ll use it later to adjust our sauce.
Step 2: Cook the Protein
Season your chicken or shrimp with salt, black pepper, and one teaspoon of Cajun seasoning. Heat one tablespoon of olive oil in a skillet over medium-high heat and sear your protein until it’s fully cooked through. This step adds flavor and texture—set it aside once done.
Step 3: Sauté the Veggies
In that same skillet (keeping all those tasty bits!), add your remaining olive oil and butter. Toss in those vibrant bell peppers and minced garlic. Sauté them for about 3–4 minutes until they soften up; this brings out their natural sweetness that’ll complement our spicy flavors beautifully.
Step 4: Build the Sauce
Now it’s time to get saucy! Stir in the remaining Cajun seasoning along with smoked paprika and red pepper flakes. Toasting these spices for about 30 seconds really enhances their flavors. Pour in your heavy cream next—watch as it transforms into a rich sauce! Stir in grated Parmesan until everything is creamy goodness.
Step 5: Combine Everything
Add that cooked penne along with your protein back into the skillet. Give everything a good stir so every bite gets coated in that luscious sauce. If things seem a little thick, gradually add reserved pasta water until you reach your desired consistency.
Step 6: Garnish and Serve
Taste and adjust seasoning as needed; then garnish with fresh herbs and a squeeze of lime juice right before serving hot! Your Spicy Rattlesnake Pasta is ready to be enjoyed—trust me, everyone will be asking for seconds!
Pro Tips for Making Spicy Rattlesnake Pasta

Don’t skip the pasta water: The starch in reserved pasta water helps to create a creamy sauce that clings beautifully to the pasta. It’s a simple trick that makes a big difference in texture.
-
Let it rest before serving: Allowing the dish to sit for a few minutes after cooking helps the flavors meld together even more, resulting in a richer taste experience.
