Step‑by‑Step Instructions for Spicy Rattlesnake Pasta
Step 1: Cook Pasta
Bring a large pot of salted water to a rolling boil over high heat. Add 12 oz of penne pasta and cook for about 9-11 minutes until just al dente, stirring occasionally. Once cooked, drain the pasta in a colander and set it aside. This base is essential for holding the luscious Cajun sauce in the Spicy Rattlesnake Pasta.
Step 2: Sauté Protein
In a large skillet over medium heat, melt 2 tablespoons of butter until bubbly. Add 1 chicken breast or a generous amount of shrimp and minced garlic, then sauté for 5-7 minutes until the protein is cooked through and golden brown. Remove the chicken or shrimp from the skillet and set aside; this step infuses the dish with rich flavor.
Step 3: Sauté Vegetables
In the same skillet, toss in 3 mixed-color bell peppers, sliced for vividness and sweetness. Sauté them for about 5 minutes until they become tender and slightly charred. This process adds depth to the Spicy Rattlesnake Pasta by creating a sweet contrast against the spicy sauce.
Step 4: Make Sauce
Reduce the heat to low and add 2 teaspoons of Cajun seasoning and ½ teaspoon of red pepper flakes to the skillet. Pour in 1½ cups of heavy cream, stirring continuously to combine the flavors. Allow the mixture to simmer gently for about 3-4 minutes, letting it thicken slightly while releasing a delightful aroma throughout your kitchen.
Step 5: Combine
Return the sautéed chicken or shrimp to the skillet along with the drained penne pasta. Toss everything together in the creamy sauce until well coated; this should take about 2-3 minutes. Stir in ½ cup of grated Parmesan cheese, allowing it to melt into the sauce, creating a luscious finish to your Spicy Rattlesnake Pasta.
Step 6: Serve
Plate your Spicy Rattlesnake Pasta generously and enjoy it hot. You may want to garnish with additional Parmesan cheese and a sprinkle of cracked black pepper for that extra touch. Pair it with a crisp green salad or crusty bread to complement the meal, and dive into the bold flavors!
