Instructions
Start by cooking the penne pasta. Fill a large pot with water and add salt. Bring it to a boil and add the pasta. Cook until al dente, about 8-10 minutes. Drain and set aside.
While the pasta cooks, cut the chicken into bite-sized pieces. Season them with Cajun spice. Heat 1 tablespoon of olive oil in a skillet over medium-high heat. Add the chicken and cook for 5-7 minutes until browned. Remove and set aside.
Next, slice your veggies. Add another tablespoon of oil to the skillet. Toss in the peppers, onion, garlic, and jalapeños. Cook for about 5 minutes until tender-crisp. Remove from the pan.
Now it’s time for the sauce. Melt butter in the skillet over medium heat. Add flour and whisk for 1-2 minutes. Slowly pour in the milk, whisking constantly to avoid lumps.
Let the sauce simmer and thicken for 2-3 minutes. Stir in the Parmesan, salt, and pepper until smooth.
Finally, add the pasta, chicken, and veggies back to the skillet. Toss everything together until well-coated.
Sprinkle with fresh parsley and serve hot. Enjoy your homemade rattlesnake pasta!

How To Make It Diabetes-Friendly

Use whole wheat penne instead of regular pasta. This adds fiber and slows down carb absorption.

Replace half-and-half with unsweetened almond milk to lower fat and calories.
Use less Parmesan cheese or try a low-fat version to reduce saturated fat.
Add extra spices like cayenne or red pepper flakes instead of salt for flavor.
Measure your portion size carefully. Stick to about 1 cup of the finished dish per serving.
Try these optional add-ins to boost nutrition:

- Sliced mushrooms
- Zucchini noodles mixed with the pasta
These changes can help manage blood sugar while still enjoying this tasty meal. Remember to check with your doctor about how pasta fits into your diet plan.
Tips, Tricks & Storing
Don’t overcook your pasta! Cook it until it’s just shy of al dente. This way, it won’t turn mushy when mixed with the sauce.
For extra flavor, try marinating the chicken in Cajun seasoning for 30 minutes before cooking. This will make it even tastier.
You can adjust the spice level to your liking. For milder heat, remove the seeds from the jalapeños. For more kick, add a pinch of cayenne pepper.
Want to save time? Prep your veggies and chicken the night before. Store them in separate containers in the fridge.
Got leftovers? Cool the pasta completely, then store it in an airtight container. It will keep in the fridge for up to 3 days.
To reheat, add a splash of milk to the pasta and warm it gently on the stove. Stir often to prevent sticking.
For a veggie version, swap the chicken for roasted vegetables like zucchini or mushrooms. You’ll still get a delicious meal!
Remember to grate your own Parmesan cheese if possible. It melts better than pre-grated and adds more flavor.
