Step‑by‑Step Instructions for Spicy Rattlesnake Pasta
Step 1: Prep Ingredients
Begin by dicing about one pound of chicken or shrimp into bite-sized pieces. Chop one cup of bell peppers into strips and finely mince two cloves of garlic along with half a medium onion. Measure out your Cajun seasoning, red pepper flakes, and heavy cream in advance to streamline the cooking process, ensuring everything is ready to go for this tasty Spicy Rattlesnake Pasta.
Step 2: Cook Pasta
In a large pot, bring four quarts of salted water to a rolling boil over high heat. Add 12 ounces of penne pasta and cook until al dente, typically around 8-10 minutes, stirring occasionally to prevent sticking. Once done, drain the pasta in a colander and set aside for later; lightly toss with a bit of olive oil to prevent sticking while preparing the sauce.
Step 3: Sauté Base
In a large skillet, heat two tablespoons of olive oil over medium heat. Once shimmering, add the minced garlic and chopped onion, stirring frequently for about 2-3 minutes until they become fragrant and translucent. This aromatic base is crucial for our Spicy Rattlesnake Pasta’s flavor, so don’t rush this step!
Step 4: Add Protein
Introduce the diced chicken or shrimp into the skillet, cooking for about 4-5 minutes until golden brown and cooked through. Make sure to stir frequently to ensure even cooking and to combine the flavors. The protein adds depth to the dish, so this step is essential before we move onto the vegetables.
Step 5: Incorporate Veggies
Once the protein is cooked, add the chopped bell peppers to the skillet. Continue cooking for 3-4 minutes, stirring occasionally, until they soften slightly while still maintaining some crunch. The vibrant colors and flavors of the bell peppers will bring your Spicy Rattlesnake Pasta to life, so enjoy the sight and aroma!
Step 6: Make Sauce
Pour in one cup of heavy cream along with your prepared Cajun seasoning and red pepper flakes. Stir everything together and let the sauce simmer for about 5 minutes on low heat, allowing it to thicken slightly. As it bubbles, the sauce will develop a rich, creamy texture that perfectly complements the pasta.
Step 7: Combine
Add the drained penne pasta directly into the skillet with the sauce, tossing gently to combine thoroughly. If the sauce is too thick, gradually add a bit of reserved pasta water, a tablespoon at a time, until the desired consistency is achieved. This beautiful amalgamation creates the bold flavors of Spicy Rattlesnake Pasta that will delight your taste buds.
Step 8: Serve
Remove the skillet from heat. Serve the Spicy Rattlesnake Pasta hot, garnishing with your choice of cheese, such as Parmesan or Monterey Jack, if desired. A sprinkle of freshly cracked black pepper or additional Cajun seasoning can enhance the flavors even further. Enjoy this comforting dish and the delightful reactions it brings from family and friends!

Spicy Rattlesnake Pasta Recipe FAQs
