Step‑by‑Step Instructions for Rattlesnake Pasta
Step 1: Cook the Pasta
Begin by bringing a large pot of salted water to a boil over high heat. Add the penne pasta and cook according to package instructions until al dente, usually about 8-10 minutes. Once cooked, drain the pasta in a colander, giving it a quick rinse under cool water to stop the cooking process, then set it aside for later.
Step 2: Sauté the Chicken
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Once the oil is shimmering, add the diced chicken breasts seasoned with Cajun seasoning. Sauté for about 5-7 minutes, stirring occasionally until the chicken is golden brown and cooked through, with no pink remaining. Remove the chicken from the skillet and set aside temporarily.
Step 3: Cook the Vegetables
In the same skillet, add the chopped red and green bell peppers, red onion, and minced garlic. Sauté the vegetables for about 3-4 minutes, stirring often, until they become tender and fragrant. The vibrant colors will brighten your kitchen as they soften, adding a wonderful aroma to your Rattlesnake Pasta.
Step 4: Prepare the Roux
Stir in the chopped jalapeños and 2 tablespoons of butter, allowing it to melt completely. Once melted, sprinkle in 2 tablespoons of all-purpose flour, stirring continuously for about 1-2 minutes. This roux will begin to thicken and should form a paste; keep an eye on it to ensure it doesn’t brown.
Step 5: Make the Creamy Sauce
Gradually whisk in 1 cup of milk or half-and-half to the roux, ensuring a smooth consistency as you mix. Increase the heat slightly, bringing the mixture to a gentle simmer for about 3-5 minutes until it thickens. This creamy base will coat the pasta beautifully, creating that signature texture for your Rattlesnake Pasta.
Step 6: Add Parmesan and Seasonings
Stir in 1 cup of grated Parmesan cheese, allowing it to melt into the sauce, creating a rich and cheesy flavor. Season the sauce with salt and black pepper to taste, mixing well to ensure every bite of your Rattlesnake Pasta is full of flavor. Look for a creamy consistency without lumps.
Step 7: Combine Pasta and Sauce
Gently fold the cooked penne pasta into the sauce, stirring until every piece is well-coated. Continue to heat the mixture for an additional 2-3 minutes over low heat, letting the flavors meld and ensuring your pasta is warmed through. The creamy sauce will cling to the pasta, rich and inviting.
Step 8: Serve and Garnish
Once everything is combined and heated, remove the skillet from heat. Serve your Rattlesnake Pasta immediately, garnished with chopped fresh parsley for a pop of color and a hint of freshness. This final touch not only enhances the presentation but also adds a delightful flavor to each bite.

Make Ahead Options
Preparing Rattlesnake Pasta in advance is a fantastic way to save time during those busy weeknights! You can cook the penne pasta and sauté the chicken with Cajun seasoning up to 24 hours ahead of time, storing them separately in airtight containers in the fridge. The sautéed vegetables can also be prepared ahead and refrigerated for 3-4 days. To maintain the creamy texture, combine the pasta and sauce just before serving; simply reheat the cooked ingredients in a skillet over low heat, adding a splash of milk if needed to loosen the sauce. This way, your Rattlesnake Pasta will be just as delicious with minimal effort when it’s time to eat!
