This rattlesnake pasta delivers a perfect balance of creaminess and heat that will wake up your taste buds without overwhelming them. The name comes from the "bite" of the jalapeños, not actual rattlesnake meat! My family requests this delicious one-pot wonder at least twice a month, and it never disappoints.
I developed this recipe during a particularly busy season when I needed dinner solutions that didn't sacrifice flavor. The combination of jalapeños and two cheeses became an instant hit that even my spice-sensitive friends enjoy.
Ingredients
- Pickled jalapeños: Add controlled heat and tangy flavor without being overpowering. Look for ones packed in vinegar for best results
- Fresh garlic: Provides aromatic depth. Choose firm bulbs with tight skin for maximum flavor
- Boneless skinless chicken breast: Creates a protein-rich base. For juicier results, slice against the grain
- Dried penne pasta: Holds up well in one-pot cooking. Its tubular shape captures the creamy sauce beautifully
- Unsalted chicken stock: Forms the cooking liquid. Using unsalted allows better seasoning control
- Red bell pepper: Contributes sweetness and color contrast. Select firm peppers with glossy skin
- Heavy whipping cream: Creates silky texture. Full-fat version yields the best mouthfeel
- Parmesan cheese: Adds nutty depth and thickens the sauce. Freshly grated melts much better than pre-packaged
- Cheddar cheese: Provides color and sharp flavor. Medium or sharp varieties work equally well
Step-by-Step Instructions
- Bloom The Aromatics:
- Heat olive oil in a Dutch oven until it shimmers and moves easily across the pan. Add chopped jalapeños and garlic, stirring continuously to prevent burning. Watch for the moment when the garlic becomes intensely fragrant but not browned, typically 30-60 seconds. This brief cooking releases essential oils without bitterness.
- Create The Base:
- Add chicken pieces, distributing them evenly across the pot. Immediately add the dry pasta and pour in chicken stock. Bring everything to a vigorous boil where large bubbles consistently break the surface. Let ingredients cook uncovered for exactly 4 minutes, stirring occasionally to prevent sticking and ensure even cooking.
- Simmer To Perfection:
- Reduce heat until you see gentle bubbles rather than a rolling boil. Cover with a tight-fitting lid and maintain a simmer for 10-12 minutes. Stir every few minutes to prevent pasta from sticking to the bottom. Look for pasta that offers slight resistance when bitten and a small amount of thickened liquid remaining in the pot. If pasta needs more time but liquid is low, add a splash more stock.
- Develop The Sauce:
- Uncover the pot and introduce diced bell peppers, which will maintain slight crispness. Pour in heavy cream in a slow stream while stirring continuously to incorporate. Add salt and stir thoroughly to distribute. Notice how the liquid begins transforming into a silky sauce as it combines with the starchy pasta water.
- Create Cheesy Richness:
- Remove from heat completely before adding cheese to prevent separation. Add Parmesan in smaller portions, stirring until completely melted before adding more. The sauce will noticeably thicken with each addition. Fold in half the cheddar, stirring until no visible cheese pieces remain. Taste and adjust salt until flavors pop without being overtly salty.

The real secret to this dish is the starchy pasta water that combines with the cheese to create an emulsified sauce without needing any flour or cornstarch. I discovered this technique after years of making more complicated cheese sauces and now use it for nearly all my pasta dishes.
Make-Ahead Options
This pasta reheats beautifully the next day, making it perfect for meal prep. Store in airtight containers in the refrigerator for up to 3 days. When reheating, add a splash of milk or cream to restore the creamy texture, as the pasta will continue absorbing liquid as it sits.
Spice Adaptations
The beauty of this recipe lies in its adaptability to different heat preferences. For a milder version, reduce jalapeños to 1 tablespoon and rinse them before chopping to remove some heat. For spice lovers, add a minced fresh jalapeño along with the pickled ones, or substitute part of the bell pepper with poblano for deeper flavor with moderate heat.
Serving Suggestions
Serve this hearty pasta with a simple side salad dressed with lemon vinaigrette to cut through the richness. For a complete meal, add garlic bread for soaking up extra sauce. I love setting out additional toppings like sliced avocado, extra jalapeños, and various hot sauces so everyone can customize their bowl.

Rattlesnake pasta combines bold flavors and creamy richness for a one-pot recipe that delivers on both convenience and taste.
Frequently Asked Questions
- → Why is it called Rattlesnake Pasta?
The name 'Rattlesnake Pasta' refers to the spicy 'bite' from the jalapeños. It's a playful name for this creamy pasta dish with a kick, similar to how a rattlesnake has a warning 'rattle' before its bite.
- → Can I adjust the spice level?
Absolutely! You can adjust the heat by using more or less jalapeños. For a milder version, remove the seeds from the jalapeños or substitute with mild green chiles. For extra heat, add more jalapeños or include a dash of cayenne pepper.
- → What can I substitute for heavy cream?
You can substitute heavy cream with half-and-half for a lighter option. For a dairy-free alternative, try full-fat coconut milk or cashew cream, though this will change the flavor profile slightly.
- → Can I make this dish ahead of time?
This pasta is best enjoyed fresh, as the sauce may thicken when refrigerated. If making ahead, consider undercooking the pasta slightly and adding a splash of chicken stock when reheating to revive the creamy consistency.
- → What sides pair well with Rattlesnake Pasta?
A simple green salad with vinaigrette dressing makes a perfect light side. Garlic bread or crusty Italian bread is excellent for soaking up the delicious sauce. For a more substantial meal, consider serving with grilled vegetables or roasted asparagus.
- → Can I use a different type of pasta?
Yes, you can substitute penne with other medium-sized pasta shapes that can trap the sauce well, such as rotini, fusilli, or farfalle. Cooking times may vary slightly based on the pasta shape chosen.
