Ingredients
Here’s everything you need to make this satisfying pasta:

- Chicken Breast: It’s lean and pairs well with Cajun spices.
- Olive Oil: You use it for sautéing the chicken and veggies.
- Cajun Seasoning, Salt, and Black Pepper: They infuse the dish with authentic Louisiana flavors.
- Veggies: Peppers and onions add color and texture to the dish.
- Butter: It creates a nice roux as the base for the sauce.
- All-Purpose Flour: It thickens the sauce so it sticks to the pasta.
- Milk or Half-and-Half: To make the dish nice and creamy. Or use heavy cream to up the decadence even more.
- Parmesan Cheese: It brings a nutty flavor to the luscious sauce.
- Fresh Parsley: The finishing touch! It adds a nice pop of color to the pasta.

How to Make Rattlesnake Pasta
Making this pasta is so easy! Just follow these steps:
- Cook the pasta. Cook the penne pasta in salted boiling water until al dente. Drain and set aside.
- Season the chicken. Season the chicken breast pieces with Cajun seasoning.
- Cook the chicken. Heat the olive oil in a large skillet over medium-high heat. Add the seasoned chicken and cook until browned and cooked through, for about 5-7 minutes. Transfer to a plate.
- Sauté the vegetables. Add more olive oil to the skillet. Sauté the red bell pepper, green bell pepper, red onion, garlic cloves, and jalapeño peppers until tender-crisp, for about 5 minutes. Remove from the skillet.
- Make the sauce. Melt the butter in the skillet over medium heat. Whisk in the flour and cook for 1-2 minutes. Gradually whisk in the milk until smooth. Simmer until thickened, about 2-3 minutes. Stir in the grated Parmesan, salt, and pepper until melted and smooth.
- Combine and serve. Add the cooked pasta, chicken, and sautéed vegetables to the skillet with the sauce. Toss gently to coat. Serve hot, garnished with fresh parsley.

Tips For the Best Rattlesnake Pasta
For a true restaurant-worthy feast, follow these tips and tricks:
- Don’t overcook the pasta! Boil the pasta until just shy of al dente. Otherwise, it'll become mushy when tossed with the sauce and other ingredients.
- Try a pickled twist. Opt for pickled jalapeño slices instead of fresh ones for added tanginess.
- Give it a flavor boost. Add roasted garlic into the sauce for a mellow, sweet garlic flavor.
- Put some elbow grease into it. For maximum flavor, grate Parmesan cheese fresh off the block.
. - Give it an extra garnish. Sprinkle sliced green onions on top before serving for some color.
- Kick up the heat. Dial up the amount of jalapeños and Cajun seasoning to make the pasta spicier.
- Try simple swaps. Swap the chicken for shrimp, crawfish, or andouille sausage. Use penne, fettuccine or rotini pasta. Add mushrooms, spinach, or sun-dried tomatoes. Top with toasted breadcrumbs for crunch.

How to Store
If you have leftover pasta, here’s how to keep it nice and fresh:
To Store: Allow the pasta to cool completely, then transfer to an air-tight container. Store in the refrigerator for up to 3-4 days.
I don’t recommend freezing it, as the creamy sauce may separate and become grainy when thawed. The texture of the pasta and vegetables may also become mushy. Nobody wants that!
To Reheat: Reheat on the stovetop over low heat, stirring occasionally. Throw in a splash of milk or cream to revive the sauce. You can also microwave individual portions in 30-second intervals until heated through.

This is my recipe I created in boy scouts in the 80s.not bad. I have made it with all kind of noodles,as well.
Unfortunately, I purchased the wrong penne and I ended up using another pasta that I already had. It still tasted very creamy and delicious.
I only had spiral noodles! But still am amazing dinner!! I’ll be honest and will tell you i didn’t read the penis best how to points, but I’ll mention making a roux remember to have it room temp, child milk to hot flyer makes crumbles! Other than that! 💯 is what I give this recipe! Thank you!! 😋
It was really good
The sauce needs to be doubled because it’s not enough for a pound of pasta. Otherwise it tastes great!
Can you use the white sauce in the jar and would it be good?
I would make it without the meat. Looking forward to trying this.
This was amazing and so simple. I forgot the parm and had no jalapenos. Otherwise i5 was fab. Wish it had more sauce. I used a rather large pasta which took up the sauce. Thank you for this recipe.
To Jessica Roath: add milk step 4
Made this recipe for a family dinner. It was a big hit. Everyone loved it, even the kids.
Where does the milk come in??? No where does it say to add milk but recipe calls for it
Please send recipe..I can’t find where to save.
Best recipes i have seen with pasta so far today
Saved this but I will sub. The chicken for rattle snake yes rattle snake. It a very mild white meat and when I can get it i love the texture and taste.
Oh my goodness it tastes amazing. Creamy, spicy sauce can’t get enough. YUMMY 😋
I added a little more Cajun seasoning. I like spicy 🥵
This was delicious! I made a few adjustments. Instead of jalapenos, I used poblanos. I’m not a huge spice head but it definitely needed way more Cajun seasoning. I added 2 tsp to the chicken and an additional 1 tsp to the cheese sauce. Also added a healthy sprinkle of cayenne pepper. It’s perfect for a freezing cold night. Thanks!
This was super easy and extremely tasty.
I would to all of these, but without the sodium content, nutrition values I can’t touch them. I couple did, but that’s it. So I assume they’re higher than I’m allowed to eat.
Sounds deliciously spicy. can’t wait to try it.
Will use a bit more seasoning next time. Was a hit!
