Penne pasta: Perfect tubes that hold the creamy sauce in every bite and give the dish a hearty base.
Chicken breast: Boneless, skinless, and chopped for quick, even cooking – a juicy and tender protein to anchor the pasta.

Green bell pepper: Adds a fresh, slightly grassy note for balance and crunch.
Red onion: Provides a subtle sharpness and gorgeous color to the mix.
Garlic: Three cloves means every forkful has that unmistakable garlicky aroma.
Jalapeño peppers: Control the heat by using more or fewer slices – they’re the zippy “rattlesnake” signature!
Butter: Melts into the sauce, giving it a rich, luxurious texture.
All-purpose flour: Whisked into butter to start the creamy roux, making the sauce thick and silky.
Milk or half-and-half: The creamy canvas that blends all the bold flavors together seamlessly.
Parmesan cheese: Melts right into the sauce for extra depth and a lovely savory finish.
Salt: Just a pinch to balance and enhance the overall taste.
Black pepper: Adds a mild heat and rounds out the flavor.
Fresh parsley: A final pop of color and fresh, herby aroma.

How to Make Rattlesnake Pasta

Step 1: Cook the Penne Pasta

Start by bringing a big pot of salted water to a rolling boil. Add the penne and cook until it’s perfectly al dente, following the directions on your package so every noodle is toothsome and ready to soak up the creamy Cajun sauce. Once done, drain the pasta and set it aside, but keep it close—you’ll want it ready when the sauce comes together!

Step 2: Season and Cook the Chicken

Toss the bite-sized chicken pieces with your Cajun seasoning so every morsel is coated with spicy, peppery flavor. Heat half your olive oil in a large skillet over medium-high. When it’s hot, add the chicken, searing and flipping pieces until golden and cooked through—about 5 to 7 minutes. Once done, move the chicken onto a plate to prevent overcooking while you build more flavors in the pan.

Step 3: Sauté the Veggies and Peppers

Pour the remaining olive oil into the same skillet, then add the red and green bell peppers, red onion, garlic, and those signature jalapeño slices. Stir and sauté for around 5 minutes, just until the veggies are bright and tender-crisp. Take them out and set aside; you want these to keep both their color and a bit of bite!

Step 4: Make the Creamy Cajun Sauce

Melt your butter in the skillet, letting it foam before whisking in the flour. Give it a minute or so to cook off any raw taste—this roux is what gives your sauce its creamy, luxurious body. Slowly pour in the milk or half-and-half, whisking constantly so no lumps form. Keep stirring until the sauce thickens slightly, about 2 to 3 minutes. Then, stir in the Parmesan, salt, and black pepper, watching the cheese melt into a silky, fragrant sauce.

Step 5: Bring it All Together

Now for the fun part! Add the cooked pasta, Cajun chicken, and sautéed vegetables back into your skillet with the sauce. Toss everything gently with tongs or a big spoon so each noodle and morsel gets evenly coated. The fusion of Cajun spices, melty cheese, and bright veggies will be almost too tempting to resist. Serve up your Rattlesnake Pasta while it’s piping hot.

How to Serve Rattlesnake Pasta

Garnishes

The right garnish can elevate this dish from delicious to unforgettable. Sprinkle your Rattlesnake Pasta with plenty of chopped fresh parsley for freshness and a pop of green. For those who like a little more heat, a few extra jalapeño slices on top add both color and an extra kick. Finish with another shower of grated Parmesan for a creamy, savory flourish.

Side Dishes

A simple green salad tossed with a zippy vinaigrette pairs beautifully, giving your palate a crisp refresher between bites. Warm, crusty bread is a must for dunking in the sauce, while roasted vegetables or grilled corn can add more depth to the meal. If you want to keep the Cajun spirit alive, try serving with blackened shrimp or spicy corn on the cob.

Creative Ways to Present

Let your inner chef shine! Try serving Rattlesnake Pasta in individual pasta bowls with a dramatic flourish of extra herbs and cheese. For a party, serve in a large cast iron skillet set in the middle of the table so everyone can help themselves. Or, fill small ramekins and bake with a little extra cheese for an irresistible appetizer or mini entrée twist.

Make Ahead and Storage

Storing Leftovers

If you manage to have any Rattlesnake Pasta left over, you’re in luck—it makes a fantastic next-day lunch. Simply transfer cooled pasta to an airtight container and refrigerate. The flavors will deepen overnight, making for a truly satisfying encore.

Freezing

Rattlesnake Pasta can be frozen, but keep in mind the sauce may thicken or separate a bit upon thawing. For best results, cool the pasta completely then spoon it into freezer-safe containers. Freeze for up to 2 months, and defrost in the fridge before reheating gently to preserve as much creaminess as possible.

Reheating

For best results, reheat Rattlesnake Pasta gently on the stovetop over low heat, adding a splash of milk or cream if the sauce seems too thick. You can also microwave it in short intervals, stirring frequently. Take care not to overcook the chicken or veggies as you bring everything back to steaming and delicious!

FAQs

Is Rattlesnake Pasta very spicy?

The spice level is really up to you! Removing seeds from the jalapeños and adjusting the amount of Cajun seasoning lets you control the heat. As written, the dish is bold but manageable, and you can always offer hot sauce at the table for true spice lovers.

Can I substitute a different protein for the chicken?

Absolutely! Shrimp makes a fabulous alternative and cooks even faster. Sliced Andouille sausage or even tofu are also great options if you want to switch it up or keep it vegetarian.

Do I have to use penne, or will another pasta work?

While penne is classic for Rattlesnake Pasta because its tube shape catches all the cajun-creamy sauce, other sturdy pastas like rigatoni, ziti, or even rotini will work in a pinch. Use whatever you have on hand!

Is it possible to make the sauce lighter?

Certainly! You can swap half-and-half for milk, use less butter, or try a reduced-fat cheese to lighten things up. The result will still be creamy and flavorful, though a touch less rich.

Can I make Rattlesnake Pasta ahead for a dinner party?

You sure can. Prep the chicken and veggies in advance, and even cook the pasta a few hours ahead. Then just warm everything up in the skillet, toss with your sauce, and serve to wow your guests in minutes.
