Ingredients

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

  • Penne Pasta: It captures the creamy sauce and tender chicken in every bite.
  • 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:

  1. Cook the pasta. Cook the penne pasta in salted boiling water until al dente. Drain and set aside.
  2. Season the chicken. Season the chicken breast pieces with Cajun seasoning.
  3. 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.
  4. 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.
  5. 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.
  6. 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.

Rattlesnake pasta is a restaurant-worthy dish you can make at home! Penne is coated in a creamy, spicy, cheesy sauce you'll flip for.

Ingredients

  • 1 lb penne pasta

  • 1 lb boneless, skinless chicken breast, cut into bite-sized pieces

  • 2 tbsp olive oil, divided

  • 1 1/2 tsp Cajun seasoning

  • 1 red bell pepper, sliced

  • 1 green bell pepper, sliced

  • 1/2 red onion, sliced

  • 3 cloves garlic, minced

  • 2-3 jalapeño peppers, sliced (remove seeds for less heat)

  • 4 tbsp butter

  • 1/4 cup all-purpose flour

  • 2 cups milk or half-and-half

  • 1 cup grated Parmesan cheese

  • 1/2 tsp salt

  • 1/4 tsp black pepper

  • 1/4 cup chopped fresh parsley

Instructions

  • Cook the penne pasta in a large pot of salted boiling water according to package directions until al dente. Drain and set aside.
  • While the pasta cooks, season the chicken pieces with the Cajun seasoning. Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add the chicken and cook until browned and cooked through, for about 5-7 minutes. Transfer to a plate.
  • Add the remaining 1 tbsp olive oil to the skillet. Add the bell peppers, onion, garlic and jalapeños. Sauté until the vegetables are tender-crisp, about 5 minutes. Remove from the skillet.
  • Melt the butter in the same skillet over medium heat. Whisk in the flour and cook for 1-2 minutes. Gradually whisk in the milk until smooth.
  • Bring the sauce to a simmer and cook until it starts to thicken, about 2-3 minutes. Stir in the Parmesan cheese, salt, and pepper until melted and smooth.
  • Add the cooked pasta, chicken, and sautéed vegetables to the skillet with the sauce. Toss gently until everything is well coated.
  • Serve the rattlesnake pasta hot, garnished with chopped parsley. Enjoy the creamy, spicy flavors!

Notes

  • Adjust the spice level by using more or less jalapeños, or substituting with milder peppers like poblanos.
  • For extra flavor, use a combination of Parmesan and Asiago or Romano cheeses in the sauce.
  • Add a splash of white wine or chicken broth to the sauce for more depth of flavor.
  • Substitute shrimp for the chicken for a seafood version.

    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.

  2. Lizzy Boykin says:

    Sounds deliciously spicy. can’t wait to try it.

  3. Terri says:

    Will use a bit more seasoning next time. Was a hit!

  4. Sarah Wernham says:

    Absolutely delicious. I added more Cajun which made it quite hot. Sauce was lovely & everyone really enjoyed it.

  5. Linda L. Potter says:

    This pasta dish was truly restaurant quality.
    I used ground pork because the chicken I thought I had I didnt.I seasoned it with Badia complete and Creole spice. Added mushrooms and all was right with the world…it was amazing. Thank you for the recipe.

    1. NaTaya Hastings says:

      “because the chicken I thought I had I didn’t”

      I swear, Linda, I think that sums up the story of my life. Haha.

      But I’m so glad you enjoyed the pasta!

  6. Diane Masucci says:

    Can’t find the SAVE tap 🙄. Definitely want to save this one!

    1. NaTaya Hastings says:

      Hi, Diane!

      Our save feature disappeared due to a glitch with the most recent site update. Kim got it fixed, though, so I emailed the recipe to you today. 🙂

  7. Ash says:

    It was really good and everyone loved it, but it was not spicy at all. Maybe my jalapeños just weren’t that spicy. I’ll try adjusting the spice for my heat lovers next time.

    1. NaTaya Hastings says:

      I always think it’s funny how certain things are spicy to some people and not at all to others.

      My grandmother and I LOVE spicy food. But we can rarely find anything that’s ACTUALLY spicy (to us). Then, there’s my mom, who we both affectionately call, “a wimpy.” (That was my grandpa’s favorite insult when he was alive — not “wimpy” but “A wimpy.” haha) She can’t handle even the tiniest amount of heat without claiming her mouth is on fire.

      So yes. If this wasn’t spicy for you, feel free to dial up the heat! 🙂

  8. Michelle says:

    I’ve made this twice, it’s amazing! The only thing I did was add more seasoning and then the second time I made it I added cream cheese to my sauce because my family is crazy for cream cheese and it turned out so good!

    1. Claire Wells says:

      Hi Michelle!
      So happy you liked it.
      And thanks for the cream cheese tip! I’ll have to try that next time 🙂
