If you’re looking for a dish that wakes up your taste buds and brings peppery, cheesy comfort to the table, you’ve just found your new favorite.

Ingredients You’ll Need

The magic of Rattlesnake Pasta is how a handful of well-chosen, easy-to-find ingredients can create something that feels totally restaurant-worthy. Each ingredient adds a layer—whether it’s spice, richness, or freshness—that makes this dish a dazzling combination.

Penne pasta: The perfect pasta shape for holding onto that creamy, spicy sauce in every perfect bite.
Boneless, skinless chicken breast: Lean and meaty, it soaks up the Cajun flavors and adds heartiness to the dish.
Olive oil: Used for sautéing and bringing together all those fantastic flavors.
Cajun seasoning: This is where the magic happens—just the right kick of spice and flavor.
Red bell pepper: Sweet, colorful, and provides a slight crunch.
Green bell pepper: Adds a fresh, earthy flavor and beautiful contrast.
Red onion: A touch of sweetness and color to complement the heat.
Garlic: Essential for that aromatic foundation—don’t skip it!
Jalapeño peppers: For a spicy, rattlesnake bite, adjust the amount for your spice level preference.
Butter: Transforms the sauce into something silky and rich.
All-purpose flour: Key for thickening the sauce without weighing it down.
Milk or half-and-half: The creamy base that makes the sauce irresistible.
Parmesan cheese: Adds bold, salty cheesiness and helps the sauce cling to the pasta.
Salt and black pepper: Classic seasonings to balance and enhance all the flavors.
Fresh parsley: A final, fragrant burst of color and brightness just before serving.

How to Make Rattlesnake Pasta

Step 1: Cook the Pasta

Bring a large pot of salted water to a rolling boil and add the penne pasta. Give it a good stir and cook until just al dente (check your package’s timing for guidance). You want it to have a bit of bite since it’ll keep cooking as it soaks up the sauce. Once done, drain the pasta and set it aside while you prepare the other layers of flavor.

Step 2: Season and Sauté the Chicken

While your pasta cooks, toss the bite-sized chicken pieces with that zippy Cajun seasoning. In a large skillet over medium-high heat, drizzle in half the olive oil. When it’s shimmering, add the chicken and let it sizzle until browned and fully cooked, about 5-7 minutes. Scoop it out to a plate to rest—the flavor party is just beginning!

Step 3: Sauté the Vegetables

Add the rest of the olive oil to your skillet, then toss in the sliced bell peppers, onion, minced garlic, and those spicy jalapeños. Stir and sauté everything for about 5 minutes, just until the veggies are bright and slightly tender but still have some crunch. This fresh kick is what really takes Rattlesnake Pasta over the top.

Step 4: Make the Creamy Parmesan Sauce

Turn the heat down to medium, then melt the butter in the same skillet, letting it mingle with the flavorful bits left behind. Add the flour and whisk for a minute or two. This cooks off the raw flour taste and lays the foundation for your sauce. Slowly whisk in the milk (or half-and-half), making sure it stays smooth and lump-free the whole time.

Step 5: Thicken the Sauce

Bring the sauce to a gentle simmer and let it bubble for 2-3 minutes until it thickens. Now, stir in the Parmesan cheese, salt, and black pepper. Watch the cheese melt and the sauce become completely smooth and glossy—it should coat the back of a spoon when it’s ready for the final mix.

Step 6: Combine Everything

Time for the big finish! Return the drained pasta, cooked chicken, and sautéed veggies to the skillet of sauce. Toss gently (but thoroughly) so that every single piece gets luxuriously coated. You’ll see all those beautiful colors and textures come together right before your eyes—now it’s truly Rattlesnake Pasta.

How to Serve Rattlesnake Pasta

Garnishes

Rattlesnake Pasta deserves a finishing touch! Sprinkle lots of fresh, chopped parsley for color and a pop of herby freshness. If you want to add even more zing, try a little extra grated Parmesan, a pinch of red pepper flakes, or a drizzle more olive oil right before serving.

Side Dishes

For a meal this bold, keep your sides simple. A crisp green salad with a citrusy vinaigrette balances out the richness. Garlic bread or warm focaccia is perfect for scooping up any extra sauce—trust me, you won’t want to leave a drop behind!

Creative Ways to Present

Think beyond the bowl! Serve Rattlesnake Pasta in individual cast iron pans for a rustic vibe or in a big family-style platter loaded with extra parsley and colorful bell peppers. For parties or potlucks, you can make it ahead and bake it with a little mozzarella for a bubbling, golden twist.

Make Ahead and Storage

Storing Leftovers

If you have leftovers (and you might need to hide some away for yourself), store Rattlesnake Pasta in an airtight container in the fridge for up to 3 days. The flavors intensify overnight, making it even better for lunch the next day!

Freezing

You can freeze Rattlesnake Pasta for those nights you want something cozy in a flash. Let it cool completely before transferring to freezer-safe containers or bags. It’ll keep well for up to 2 months. When you’re ready, thaw overnight in the fridge for best results.

Reheating

Warm up refrigerated or thawed Rattlesnake Pasta gently on the stove over low heat, adding a splash of milk if needed to revive the creamy sauce. A quick zap in the microwave works too—stir halfway through to make sure it heats evenly.

FAQs

How spicy is Rattlesnake Pasta?

You can control the heat! Use fewer jalapeños (and remove the seeds) for mild heat, or keep them in for a real kick. The Cajun seasoning also brings warmth, so adjust to suit your preference.

Can I use a different protein instead of chicken?

Absolutely! Shrimp, sliced sausage, or even tofu make great alternatives. Just adjust the cooking time so your protein of choice is cooked through before mixing with the sauce, pasta, and veggies.

Is there a gluten-free option for Rattlesnake Pasta?

Yes! Substitute your favorite gluten-free penne and use a gluten-free all-purpose flour blend for the sauce. Double-check your Cajun seasoning to make sure it’s gluten free as well.

What’s the best way to make Rattlesnake Pasta less rich?

Swap the half-and-half for regular milk or even a mix of milk and chicken broth to lighten the sauce. You can also use less Parmesan or opt for a light hand with the butter.

Can I make this vegetarian?

Definitely! Just skip the chicken and load up on more bell peppers, extra onions, or even asparagus and mushrooms. The creamy, spicy sauce pairs perfectly with any kind of veggie medley.
