Every ingredient in Rattlesnake Pasta plays a starring role, from the heat of the peppers to the creaminess of the sauce. You don’t need anything fancy—just these straightforward staples that combine to make magic in your skillet.
- Fettuccine pasta: The classic base that soaks up all the luscious sauce; you can use gluten-free if needed.

- Boneless skinless chicken breasts: Sliced into strips for quick, even cooking and maximum flavor absorption.

- Salt: Essential for seasoning both the chicken and the sauce; brings out all the flavors.
- Black pepper: Adds a gentle bite and balances the creaminess.
- Unsalted butter: Creates a rich base for sautéing the aromatics and building the sauce.
- Garlic: Fresh minced garlic gives the sauce a deep, aromatic kick.
- Jalapeño: Finely chopped for just the right amount of fresh, bright heat.
- Red bell pepper: Diced for a pop of sweetness and gorgeous color.
- Heavy cream: The backbone of that silky, dreamy sauce.

How to Make Rattlesnake Pasta
Step 1: Cook the Pasta
Start by bringing a large pot of salted water to a boil. Add the fettuccine and cook according to the package instructions until al dente. Drain the pasta and set it aside—don’t forget to reserve a splash of pasta water in case you want to loosen the sauce later.
Step 2: Season and Sauté the Chicken
While the pasta cooks, heat the olive oil in a large skillet over medium-high heat. Toss your chicken strips with Cajun seasoning, salt, and black pepper, then add them to the skillet. Sauté for 5 to 6 minutes until they’re golden-brown and cooked through. Once done, transfer the chicken to a plate and keep it handy for later.
Step 3: Sauté the Aromatics
In the same skillet, melt the butter. Add the minced garlic, chopped jalapeño, and diced red bell pepper. Sauté everything for 2 to 3 minutes, just until the peppers soften and the garlic becomes fragrant. This is where the base of your Rattlesnake Pasta sauce starts to come alive.
Step 4: Make the Creamy Cajun Sauce
Pour the heavy cream into the skillet and bring it to a gentle simmer. Stir in the grated Parmesan cheese and, if you’re feeling bold, the crushed red pepper flakes. Let the sauce bubble for 3 to 4 minutes, whisking occasionally, until it thickens slightly and the cheese is fully melted.
Step 5: Bring It All Together
Return the cooked chicken and drained fettuccine to the skillet. Toss everything together until the pasta is thoroughly coated in the creamy, spicy sauce, and the chicken is evenly distributed. Finish with a generous sprinkle of chopped parsley and a squeeze of fresh lemon juice. Serve your Rattlesnake Pasta immediately while it’s hot and irresistible.
How to Serve Rattlesnake Pasta

Garnishes
For that restaurant-worthy finish, top your Rattlesnake Pasta with a little extra grated Parmesan, a handful of fresh parsley, and perhaps a few thin slices of jalapeño for color and heat. A wedge of lemon on the side never hurts—it adds a zesty brightness right before digging in.
Side Dishes
This pasta is rich and full of flavor, so it pairs beautifully with a simple green salad tossed in a citrusy vinaigrette. Garlic bread or a warm baguette is also a classic choice, perfect for soaking up any leftover sauce. If you want to keep things light, roasted or steamed veggies like asparagus or broccoli are fantastic alongside Rattlesnake Pasta.
Creative Ways to Present
If you’re making Rattlesnake Pasta for guests, try serving it in shallow bowls with a sprinkle of microgreens or edible flowers for an elegant touch. For a family-style meal, pile the pasta high on a large platter and let everyone help themselves. You could also serve individual portions in mini cast iron skillets for a fun twist.
Make Ahead and Storage
Storing Leftovers
Leftover Rattlesnake Pasta keeps well in the fridge for up to 3 days. Transfer any extras to an airtight container, making sure the noodles are well coated in sauce to prevent them from drying out. This way, you’ll have a delicious lunch or quick dinner ready to go.
Freezing
While the creamy sauce is best enjoyed fresh, you can freeze Rattlesnake Pasta if needed. Place cooled pasta in a freezer-safe container and freeze for up to one month. When ready to enjoy, thaw overnight in the fridge before reheating gently on the stove with a splash of cream or milk to revive the sauce.
Reheating
To reheat, add a little water, milk, or cream to a skillet and warm the pasta over low heat, gently stirring until everything is hot and creamy again. The microwave works too, but be sure to stir often for even heating. Just take care not to overcook, as the chicken and pasta can dry out.
FAQs
Can I make Rattlesnake Pasta less spicy?
Absolutely! Simply reduce or omit the jalapeño and crushed red pepper flakes. You’ll still get all the creamy, savory flavors without the extra heat.
What other proteins can I use instead of chicken?
Shrimp is a fantastic alternative and cooks quickly in the same skillet. You can also try sliced sausage or even tofu for a different twist on Rattlesnake Pasta.
Is there a way to make this dish gluten-free?
Yes! Just swap the regular fettuccine for your favorite gluten-free pasta. All the other ingredients are naturally gluten-free, so you won’t miss any of the flavor or texture.
Can I prepare any part of Rattlesnake Pasta ahead of time?
You can cook the chicken and even chop the peppers ahead of time. Store them in the fridge and, when you’re ready, the actual cooking process comes together in under 30 minutes.
How do I make the sauce extra creamy?
For an ultra-luxurious sauce, stir in a tablespoon of cream cheese along with the Parmesan. It melts right in and gives your Rattlesnake Pasta an extra level of richness.
