I love this recipe because it’s fast, filling, and packed with flavor in every forkful. I get smoky Cajun seasoning, sweet bell peppers, and a creamy Parmesan sauce that clings to the pasta. I also like how easy it is to control the heat, so I can keep it mild or make it seriously spicy depending on my mood.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
1 lb chicken breast, cut into bite-size pieces
12 oz penne pasta
Salt, to taste
Black pepper, to taste
2 tsp Cajun seasoning (adjust to heat level)
1 tsp paprika
2 tbsp olive oil
Veggies
1 red bell pepper, sliced
1 green bell pepper, sliced
1 jalapeño, seeded and diced (optional)
2 cloves garlic, minced
Creamy Sauce
2 tbsp butter
1 cup heavy cream
½ cup chicken broth
¾ cup grated Parmesan cheese
½ tsp Italian seasoning
Garnish
Extra grated Parmesan
Chopped parsley
Directions
I cook the penne in salted water according to the package directions, drain it, and set it aside.
I season the chicken pieces with salt, black pepper, Cajun seasoning, and paprika.
I heat the olive oil in a large skillet over medium-high heat, add the chicken, and cook it until golden and cooked through, then I remove it to a plate.
In the same skillet, I add the butter and sauté the bell peppers and jalapeño until they’re slightly tender.
I add the garlic and cook it for about 30 seconds until fragrant.
I pour in the heavy cream and chicken broth and let it simmer for 3–4 minutes until it thickens a bit.
I stir in the Parmesan and Italian seasoning until the sauce turns smooth and creamy.
I add the cooked pasta and chicken back into the skillet and toss everything until fully coated.
I taste and adjust seasoning, then I finish with chopped parsley and extra Parmesan.
Servings and timing
Yield: 4 servings
Prep time: 15 minutes
Cook time: 25 minutes
Total time: 40 minutes
Variations
Extra spicy: I leave some jalapeño seeds in, add a pinch of cayenne, or use a hotter Cajun seasoning blend.
Milder version: I skip the jalapeño and use less Cajun seasoning, then I add more paprika for flavor without as much heat.
Different pasta: I use rigatoni or rotini when I want more sauce trapped in the pasta.
Protein swap: I make it with shrimp or sliced smoked sausage, and I adjust cooking time so nothing overcooks.
Veggie add-ins: I toss in mushrooms or onions with the peppers, or I add a handful of spinach at the end to wilt into the sauce.
storage/reheating
I store leftovers in an airtight container in the refrigerator for up to 3 days.
To reheat, I warm it gently in a skillet over medium-low heat with a splash of chicken broth, milk, or cream to loosen the sauce. If I use a microwave, I heat it in short bursts and stir often so the sauce stays creamy instead of separating.
FAQs
Why is it called “Rattlesnake Pasta” if there’s no rattlesnake meat?
I treat the name as a reference to the spicy “bite.” I keep at least a little heat in the sauce so it tastes true to the name.
Can I use pre-cooked or rotisserie chicken?
I can, and I like it for speed. I season it lightly and add it at the end just long enough to heat through so it doesn’t dry out.
What if my sauce gets too thick?
I loosen it with a splash of chicken broth or a little cream and toss again until it coats the pasta the way I like.
What if my sauce looks grainy?
I keep the heat lower when I add Parmesan and stir constantly. I also use finely grated Parmesan so it melts smoothly.
How do I keep the chicken tender?
I cut the pieces evenly and cook them just until done. I also let them rest on a plate while I make the sauce, then I add them back at the end so they don’t overcook.
Conclusion
I make this Rattlesnake Pasta when I want something creamy, spicy, and satisfying without spending all night cooking. I love the Cajun-seasoned chicken, the peppers, and the rich Parmesan sauce, and I keep the heat adjustable so it always matches what I’m craving.
Bold, creamy Cajun-style penne with tender chicken, peppers, and a spicy Parmesan cream sauce—quick, restaurant-famous comfort food with a serious kick.

Ingredients
Pasta + Chicken
12 oz penne pasta
1 lb chicken breast, cut into bite-size pieces
Salt & black pepper, to taste
2 tsp Cajun seasoning (adjust to heat level)
1 tsp paprika
2 tbsp olive oil
Veggies
1 red bell pepper, sliced
1 green bell pepper, sliced
1 jalapeño, seeded and diced (optional)
2 cloves garlic, minced
Creamy Sauce
2 tbsp butter
1 cup heavy cream
½ cup chicken broth
¾ cup grated Parmesan cheese
½ tsp Italian seasoning
Garnish
Extra grated Parmesan
Chopped parsley
Instructions
Cook the pasta: Boil penne in salted water according to package directions until al dente. Drain and set aside.
Season the chicken: Toss chicken with salt, pepper, Cajun seasoning, and paprika.
Cook the chicken: Heat olive oil in a large skillet over medium-high heat. Add chicken and cook until golden and cooked through. Remove to a plate.
Sauté the peppers: In the same skillet, melt butter. Add bell peppers and jalapeño and sauté until slightly tender.
Add garlic: Stir in garlic and cook about 30 seconds until fragrant.
Simmer the sauce: Pour in heavy cream and chicken broth. Simmer 3–4 minutes until slightly thickened.
Make it creamy: Stir in Parmesan and Italian seasoning until smooth.
Toss everything together: Add pasta and chicken back into the skillet. Toss until fully coated.
Finish: Taste and adjust seasoning. Garnish with parsley and extra Parmesan, then serve hot.
Notes
Heat control: Use mild Cajun seasoning and skip jalapeño for a gentler version—or keep both for the classic “rattlesnake bite.”
Sauce consistency: If it gets too thick, splash in a bit more broth. If too thin, simmer 1–2 minutes longer.
Best Parmesan tip: Grate your own Parmesan for the smoothest melt (pre-shredded can turn grainy).
Add-ons: Sautéed mushrooms or onions are great here, and a squeeze of lemon brightens the cream sauce.
