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
- Step 1: Cook the penne pasta in a large pot of salted boiling water according to package directions until al dente. Drain and set aside.
- Step 2: While the pasta cooks, season the chicken pieces with the Cajun seasoning. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the chicken and cook until browned and cooked through, about 5-7 minutes. Transfer to a plate.
- Step 3: Add the remaining 1 tablespoon of olive oil to the skillet. Add the sliced bell peppers, red onion, garlic, and jalapeños. Sauté until the vegetables are tender-crisp, about 5 minutes. Remove from the skillet and set aside.
- Step 4: Melt the butter in the same skillet over medium heat. Whisk in the flour and cook for 1-2 minutes until lightly golden.
- Step 5: Gradually whisk in the milk until smooth. Bring the sauce to a simmer and cook until it starts to thicken, about 2-3 minutes.
- Step 6: Stir in the grated Parmesan cheese, salt, and black pepper until the cheese melts and the sauce is smooth.
- Step 7: Add the cooked pasta, chicken, and sautéed vegetables back to the skillet. Toss gently until everything is well coated with the sauce.
- Step 8: Serve the rattlesnake pasta hot, garnished with chopped fresh parsley. Enjoy the creamy, spicy flavors!
Tips & Variations
- Use half-and-half instead of milk for an even richer sauce.
- Remove jalapeño seeds to reduce heat or add more for extra spice.
- For a vegetarian version, replace chicken with sautéed mushrooms or tofu.
- Freshly grated Parmesan delivers better flavor than pre-grated cheese.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat or microwave with a splash of milk to loosen the sauce. Avoid overheating to prevent the sauce from separating.

Ingredients
Pasta
- 1 lb penne pasta
Chicken
- 1 lb boneless, skinless chicken breast, cut into bite-sized pieces
- 1 1⁄2 tsp Cajun seasoning
- 2 tbsp olive oil, divided
Vegetables
- 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)
Sauce
- 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
Garnish
- 1⁄4 cup chopped fresh parsley
Instructions
- Cook Pasta: Bring a large pot of salted water to a boil. Add the penne pasta and cook according to package directions until al dente. Drain the pasta and set it aside for later.
- Season and Cook Chicken: While the pasta is cooking, season the bite-sized chicken pieces evenly with Cajun seasoning. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the chicken and cook, stirring occasionally, until browned on all sides and cooked through, approximately 5 to 7 minutes. Remove the chicken from the skillet and transfer it to a plate.
- Sauté Vegetables: Add the remaining 1 tablespoon of olive oil to the same skillet. Add the sliced red bell pepper, green bell pepper, red onion, minced garlic, and sliced jalapeños. Sauté the vegetables for about 5 minutes until they become tender but still crisp. Remove the vegetables from the skillet and set them aside.
- Make the Sauce: In the same skillet, melt the butter over medium heat. Once melted, whisk in the all-purpose flour and cook for 1 to 2 minutes to form a roux, stirring constantly to avoid lumps. Gradually whisk in the milk or half-and-half until the mixture is smooth.
- Simmer and Thicken Sauce: Bring the sauce to a gentle simmer while stirring continuously. Let it cook until it thickens slightly, about 2 to 3 minutes. Then, stir in the grated Parmesan cheese, salt, and black pepper. Continue stirring until the cheese melts and the sauce becomes smooth and creamy.
- Combine Pasta, Chicken, and Vegetables: Add the cooked pasta, chicken, and sautéed vegetables back into the skillet with the creamy sauce. Toss all the ingredients gently to ensure everything is evenly coated with the sauce.
- Serve: Serve the rattlesnake pasta hot, garnished with freshly chopped parsley. Enjoy the harmonious blend of creamy, cheesy, and spicy flavors in every bite!
Notes
- For less heat, remove the seeds from the jalapeño peppers before slicing.
- You can substitute half-and-half with whole milk for a lighter version or heavy cream for an even richer sauce.
- If you prefer spicier, add an extra jalapeño or sprinkle some cayenne pepper to the Cajun seasoning.
- Parmesan cheese can be freshly grated for the best flavor.
- This dish pairs well with a green salad or garlic bread for a complete meal.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated gently on the stovetop or microwave.
