Ingredients You’ll Need

One of the best things about Rattlesnake Pasta is that every ingredient serves a delicious purpose—there’s nothing complicated here, just bold flavors working magic together! Here’s what you’ll need, plus a few notes to set you up for pasta perfection.

Penne pasta: This tubular pasta grabs and holds onto that spicy, creamy sauce in every bite.
Boneless, skinless chicken breast: Bite-sized pieces cook quickly and add satisfying protein without weighing the dish down.
Olive oil: Essential for sautéing the chicken and veggies, adding flavor depth right from the start.
Cajun seasoning: The secret weapon for an instant blast of zesty spice—homemade or store-bought both work wonderfully.
Red bell pepper: Brings sweetness and a gorgeous pop of color.
Green bell pepper: Adds earthy crunch and balances the other flavors perfectly.
Red onion: Slightly sweet and mild, it melts down beautifully while keeping its character.
Garlic: Freshly minced for a little aromatic kick no pasta should be without.
Jalapeño peppers: The star spice factor—use as much or as little as your tastebuds desire, and remember to remove the seeds for less heat!
Butter: Helps create a rich and silky sauce base (don’t skimp—it makes a difference).
All-purpose flour: Just enough to thicken the creamy sauce without making it heavy.
Milk or half-and-half: Choose your preferred level of creaminess; half-and-half gives extra richness.
Parmesan cheese: Melts into the sauce for cheesy flavor and a cheesy, umami backbone.
Salt: A pinch to bring all the flavors into harmony.
Black pepper: Freshly cracked for subtle warmth that rounds things out.
Fresh parsley: A final flourish that adds color and a burst of brightness at the end.

How to Make Rattlesnake Pasta

Step 1: Cook the Penne Pasta

Start by bringing a large pot of salted water to a boil—big bubbles, lots of salt (like the sea), so your noodles are seasoned from the inside out. Cook your penne according to the package directions until it’s gloriously al dente. Don’t forget to give it a good stir now and then so nothing sticks! When it’s ready, drain the pasta and set it aside, keeping just a splash of pasta water for later, in case you want to loosen up the sauce.

Step 2: Season and Sear the Chicken

While the pasta is bubbling away, toss your chicken pieces with Cajun seasoning, coating every nook and cranny for maximum flavor. Heat up a tablespoon of olive oil in a large skillet over medium-high heat. Slide that chicken in and let it get golden and caramelized, about 5 to 7 minutes, turning occasionally. Once cooked through, transfer to a plate to keep it juicy while you move to the next tasty step.

Step 3: Sauté the Veggies

In the same skillet, add your second tablespoon of olive oil, then toss in the bell peppers, red onion, minced garlic, and those spicy jalapeños. Stir everything together and cook until the veggies are just tender, around five minutes; you want them vibrant and still a bit crisp for a satisfying bite. Scoop the vegetables out and set aside—they’ll rejoin the party soon!

Step 4: Make the Creamy Sauce

Without even cleaning the skillet (hello, flavor!), drop in the butter and let it melt over medium heat. Sprinkle over the flour and whisk it in to create a smooth, blonde roux, cooking for a minute or two to get rid of any raw flour taste. Gradually whisk in the milk (or half-and-half), stirring constantly so you get a lovely, silky mixture with no lumps. Gently bring it to a simmer until it thickens enough to coat the back of a spoon.

Step 5: Add the Cheese and Season

Once your sauce is thickened, toss in the grated Parmesan, a pinch of salt, and crack in some black pepper. Stir till the cheese melts completely and everything mingles into a gorgeous, luscious sauce. This is where the transformation happens—the unmistakable heart of any Rattlesnake Pasta!

Step 6: Combine Everything

Now for the best part: tip in your cooked penne, juicy chicken, and sautéed veggies right into that creamy sauce. Gently toss or stir everything together, making sure every bite gets coated in that magical, spicy creaminess. If the sauce seems too thick, a splash of reserved pasta water will loosen it right up.

Step 7: Garnish and Serve

Just before you dig in, sprinkle plenty of freshly chopped parsley over the top for color and freshness. Serve your rattlesnake pasta piping hot, and get ready for a sensational, spicy, and creamy comfort food experience!

Garnishes

Finishing touches matter! The classic garnish for rattlesnake pasta is a shower of vibrant, chopped fresh parsley, which adds color and a burst of herbal flavor. For a little extra flair, try a pinch of extra Cajun seasoning or a grating of fresh Parmesan just before serving. Thin slices of fresh jalapeño on top look beautiful and warn guests this pasta packs some punch!

Side Dishes

Pairing the perfect side makes the meal truly unforgettable. A crisp green salad with a tangy vinaigrette helps balance the richness of rattlesnake pasta, while toasted garlic bread is ideal for mopping up any extra sauce. Roasted or grilled veggies, like asparagus or zucchini, add another layer of freshness to your table.

Creative Ways to Present

Serving rattlesnake pasta family-style in a big, colorful bowl is always a winner, encouraging everyone to dig in. For something a bit more elevated, plate individual servings with extra sauce drizzled over and a flourish of herbs. Or, for a party, serve smaller portions in ramekins or on crostini for a spicy, creamy appetizer everyone will remember.

Make Ahead and Storage

Storing Leftovers

Rattlesnake pasta makes fantastic leftovers! Cool it to room temperature, then transfer to an airtight container and keep in the fridge for up to three days. The flavors deepen overnight, and it’s easy to reheat for a quick, delicious lunch or dinner the next day.

Freezing

You can freeze rattlesnake pasta, though the sauce may change texture slightly after thawing. Allow the pasta to cool completely, then store in a freezer-safe container for up to two months. To help preserve creaminess, add a splash of milk or cream when reheating.

Reheating

Reheat rattlesnake pasta gently on the stove or in the microwave. Stir in a tablespoon or two of milk or water as it warms to revive that silky sauce. If using a microwave, cover loosely and stir halfway through to ensure even heating and prevent the pasta from drying out.

FAQs

Can I use a different type of pasta?

Absolutely! While penne is traditional for rattlesnake pasta because it holds sauce so well, you can use rigatoni, fusilli, or even fettuccine if you like. Choose a shape that captures the creamy, spicy sauce in every mouthful.

How can I make it less spicy?

If you’d like a milder version, remove the seeds and membranes from the jalapeños or reduce the amount used. You can also cut back a little on the Cajun seasoning to keep those Southwestern flavors balanced instead of fiery.

Can I substitute the chicken?

Yes! Sliced and sautéed Italian sausage or shrimp both make fantastic swaps for chicken in rattlesnake pasta. For a vegetarian twist, try strips of roasted mushrooms instead—the result is still deliciously hearty and satisfying.

What’s the best way to serve rattlesnake pasta at a party?

For parties, serve rattlesnake pasta in a big, beautiful serving dish and let everyone help themselves. Set out extra Parmesan, herbs, and sliced jalapeños for guests to customize their plates. You can even keep it warm in a slow cooker for buffet-style gatherings.

Do I have to use both types of bell peppers?

While the mix of green and red bell peppers adds beautiful color and a balance of sweetness and earthiness, you can use only one if that’s what you have. Yellow or orange bell peppers also work well—just use what’s on hand!
