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 tbsp 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 the chicken to a plate.
- Step 3: 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 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 to form a roux.
- Step 5: Gradually whisk in the milk until the sauce is smooth. Bring to a simmer and cook until it thickens, about 2-3 minutes.
- Step 6: Stir in the Parmesan cheese, salt, and black pepper until the cheese has melted and the sauce is creamy.
- Step 7: Add the cooked pasta, chicken, and sautéed vegetables back to the skillet. Toss gently until everything is evenly coated with the sauce.
- Step 8: Serve the rattlesnake pasta hot, garnished with chopped fresh parsley. Enjoy the creamy, spicy flavors!
Tips & Variations
- For a milder dish, remove all jalapeño seeds or reduce the number of peppers used.

Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat, adding a splash of milk if the sauce has thickened too much. Avoid microwaving at high power to preserve the creamy texture.

Instructions
