Ingredients
- Raw shrimp: peeled and deveined look for firm shrimp with no off smell or discoloration

- Sauté the Shrimp:
- Use the same skillet with flavorful fond Sprinkle shrimp well with Cajun seasoning Sauté shrimp for three to four minutes just until they turn opaque and pink Remove quickly so they do not get rubbery
- Build the Creamy Sauce:
- Lower the heat Add a dab of butter and your minced garlic Sauté just until fragrant about thirty seconds to avoid burning Slowly pour in heavy cream while stirring to loosen up brown bits Whisk in fresh grated Parmesan until silky and melted Taste and add more seasoning if needed

The Cajun seasoning is the personality of this dish I love experimenting with homemade versions to play up the smoky or spicy notes My family remembers how the kitchen smells as this comes together and everyone’s always eager for seconds
Storage Tips
Store leftovers in an airtight container in the fridge for up to two days Reheat gently over low heat with a splash of milk or cream to loosen the sauce Avoid microwaving for too long or the shrimp may become tough
Ingredient Substitutions
Try chicken thighs instead of steak if you prefer or use all shrimp for a pescatarian version
Swap in gluten free pasta if needed
Lighter cream or half and half works but the sauce will be less rich
If you do not have Parmesan try pecorino for a deeper bite but avoid bagged cheese as it will not melt smoothly
Serving Suggestions
Serve this pasta with a crisp salad of mixed greens or simple steamed green beans
A wedge of crusty garlic bread is perfect for mopping up extra sauce
Chill a light white wine or offer iced tea to balance the spicy heat
