It’s the kind of meal that feels indulgent and exciting, perfect for spicing up your usual pasta night or impressing friends at a dinner gathering. The balance of creamy cheese, smoky spice, and perfectly cooked pasta makes every bite unforgettable.

What makes this dish truly special is how adaptable it is — you can dial the heat up or down, swap in your favorite pasta, or experiment with different cheeses. Whether you’re a fan of spicy food or just looking to jazz up your comfort classics, Rattlesnake Pasta delivers on all fronts.
What Kind of Pasta Should I Use?
For Rattlesnake Pasta, penne is the classic choice because its hollow shape holds onto the creamy, spicy sauce beautifully. However, feel free to try fettuccine for a silky experience or rotini for extra texture. The key is to choose a pasta that captures the sauce in every bite.
Ingredients for the Rattlesnake Pasta
- Chicken breast: Provides lean protein and absorbs the spicy flavors beautifully.
- Penne pasta: Perfect for holding the creamy sauce and giving the dish body.
- Heavy cream: Creates a rich, velvety base for the Alfredo sauce.
- Parmesan cheese: Adds nutty, salty depth to the creamy sauce.
- Jalapeños: Bring the rattlesnake “bite” with just the right amount of heat.
- Garlic: Infuses the dish with aromatic warmth.
- Butter: Adds richness and helps sauté the chicken and garlic.
- Cajun seasoning: Provides smoky, spicy flavor to elevate the chicken.
- Salt and pepper: Essential for balancing and enhancing all the other flavors.

How To Make the Rattlesnake Pasta
Step 1: Season and Cook the Chicken
Slice the chicken breasts into strips and season them generously with Cajun seasoning, salt, and pepper. In a large skillet, melt butter over medium-high heat and sauté the chicken until golden and cooked through. Remove the chicken from the pan and set aside.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil. Add the penne pasta and cook according to package instructions until al dente. Drain and set aside, reserving about 1/2 cup of pasta water.
Step 3: Make the Creamy Sauce
In the same skillet used for the chicken, melt a bit more butter and sauté minced garlic and sliced jalapeños until fragrant, about 1-2 minutes. Pour in the heavy cream and bring to a gentle simmer. Gradually stir in the Parmesan cheese, whisking until smooth and creamy.
Step 4: Combine Everything
Return the cooked chicken to the skillet, tossing to coat it in the sauce. Add the cooked pasta, stirring to combine. If the sauce seems too thick, add a splash of the reserved pasta water until you reach the desired consistency.
Step 5: Finish and Serve
Taste and adjust seasoning with extra salt, pepper, or Cajun seasoning if desired. Serve hot, garnished with extra Parmesan, fresh herbs, or a sprinkle of crushed red pepper for added heat.
Serving and Storing Rattlesnake Pasta
Rattlesnake Pasta is best served hot and fresh, straight from the skillet. Pair it with a crisp green salad or garlic bread to balance the rich, spicy flavors. If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave, adding a splash of cream or milk to bring back the creamy texture.
