This spicy rattlesnake pasta has become my secret weapon for impressing dinner guests with minimal effort. The creamy sauce with its perfect kick of heat wraps around each piece of pasta and protein, creating a dish that feels indulgent but comes together in just half an hour.

I first made this recipe when I needed to pull together a last minute dinner party, and it's been requested at every gathering since. The combination of creamy sauce with Cajun spices creates that magical balance that makes people think you spent hours in the kitchen.

Ingredients

  • Penne pasta: absorbs the creamy sauce perfectly and holds up to the robust flavors
  • Chicken breast or shrimp: provides lean protein that takes on the spicy flavors beautifully
  • Bell peppers: add sweetness, color and a slight crunch to balance the creamy elements
  • Fresh garlic: brings essential aromatic depth that dried simply cannot match
  • Cajun seasoning: creates the signature flavor profile look for varieties with less salt for better control
  • Smoked paprika: adds smoky complexity without additional heat
  • Heavy cream: forms the luxurious base of the sauce use full fat for best results
  • Parmesan cheese: brings umami richness and helps thicken the sauce freshly grated melts much better than pre shredded

Step-by-Step Instructions

Cook the Pasta:
Bring a large pot of water to a rolling boil before adding a generous tablespoon of salt. Add your penne and cook until just slightly firmer than al dente, about one minute less than the package instructions. This undercooking is crucial as the pasta will continue cooking in the sauce. Before draining, scoop out half a cup of the starchy pasta water to help bind your sauce later.
Cook the Protein:
Pat your chicken or shrimp completely dry with paper towels this ensures proper browning rather than steaming. Season generously with salt, pepper and a teaspoon of Cajun seasoning, making sure each piece is evenly coated. Heat a large skillet over medium high heat, add oil and arrange your protein in a single layer. Cook chicken for about 4 minutes per side or shrimp for about 2 minutes per side until just cooked through. Remove and set aside on a clean plate.
Sauté the Veggies:
Without cleaning the skillet, add your remaining oil and butter to capture all the flavorful bits left from cooking the protein. Add your sliced bell peppers and sauté for about 2 minutes before adding the minced garlic. Continue cooking for another minute or two until the peppers have softened slightly but still maintain some bite. The garlic should be fragrant but not browned.
Build the Sauce:
Sprinkle the remaining Cajun seasoning, smoked paprika and red pepper flakes directly over the vegetables and stir continuously for 30 seconds. This step blooms the spices, releasing their essential oils and deepening their flavor. Pour in the heavy cream while stirring to incorporate all the spices. Allow the mixture to come to a gentle simmer before gradually adding the Parmesan, stirring constantly to create a smooth sauce.
Combine Everything:
Return your cooked protein to the skillet along with the drained pasta. Gently fold everything together, ensuring each piece of pasta is coated with the creamy sauce. If the sauce seems too thick, gradually add the reserved pasta water a tablespoon at a time until you reach your desired consistency. Let everything simmer together for 1 to 2 minutes to marry the flavors.
Garnish and Serve:
Taste and adjust the seasoning, adding more salt, pepper or Cajun spice if needed. Transfer to a serving dish or individual plates and finish with freshly chopped herbs and a bright squeeze of lime juice to cut through the richness of the cream.

My absolute favorite way to enjoy this dish is with plump Gulf shrimp and an extra sprinkle of smoked paprika on top. Something about the combination of seafood with the creamy, spicy sauce just transports me back to vacations along the Gulf Coast. My husband, who typically avoids spicy food, always makes an exception for this pasta.

Mastering Heat Levels

The beauty of this rattlesnake pasta lies in its adaptability to different spice preferences. For a mild version that children can enjoy, omit the red pepper flakes entirely and reduce the Cajun seasoning to one teaspoon total. For those who love heat, add the optional cayenne pepper and increase the red pepper flakes to a full teaspoon. The dairy in the cream sauce naturally tempers some of the heat, creating a pleasant warming sensation rather than an overwhelming burn.

Make It Your Own

This recipe welcomes creative variations. Try adding sautéed mushrooms for an earthy dimension, or toss in some fresh spinach during the final combine step to add color and nutrition. For a smokier profile, include a diced chipotle pepper in adobo sauce. Vegetarians can skip the protein entirely and double up on vegetables like zucchini, yellow squash, or eggplant. The sauce base remains delicious regardless of what you pair it with.

The Secret to Creamy Perfection

The key to preventing your cream sauce from breaking or becoming grainy lies in temperature control. Once you add the heavy cream, maintain a gentle simmer rather than a rolling boil. When incorporating the Parmesan, remove the pan from direct heat and add the cheese gradually while stirring constantly. For an even silkier texture, try replacing half the Parmesan with fontina or monterey jack cheese, which melt exceptionally well and add another layer of flavor complexity.
