Shop What I Use: White Truffle Cajun Shrimp Alfredo
This White Truffle Cajun Shrimp Alfredo comes together quickly, but using the right cookware ensures perfect texture, balanced flavor, and restaurant-quality results.
Large Pot
A large, heavy-bottomed pot gives the pasta plenty of room to cook evenly without sticking or clumping. It also helps maintain a steady boil, which is key for properly cooked, al dente pasta.
Large Skillet
A wide skillet is essential for searing the Cajun shrimp evenly while allowing space to build the Alfredo sauce without overcrowding. It helps the shrimp cook quickly and evenly while giving the sauce room to reduce and become silky and cohesive.
How to Create White Truffle Cajun Shrimp Alfredo
1
Cook Pasta
Bring a large pot of lightly salted water to a boil. Add pasta and cook for 8 to 10 minutes or until al dente and drain.
2
Sauté the Shrimp
In a large bowl, mix shrimp, salt, pepper, Cajun seasoning, and red pepper flakes. Bring a large skillet to medium-high heat and add oil. Add shrimp and sauté for 5-7 mins.
3
Build the Sauce
Lower heat to medium. Add garlic butter and grated garlic. Sauté 30 seconds until fragrant. Pour in heavy cream and bring to a gentle simmer. Stir continuously and cook 3–5 minutes until slightly thickened.
4
Combine
Return shrimp to the skillet. Add drained pasta and toss to coat. If needed, add a splash of reserved pasta water to loosen the sauce.
5
Finish with Truffle Oil
Turn off heat. Drizzle white truffle oil over the pasta and gently toss.

My Expert Tips for Success
• Add truffle oil off heat. Heat dulls its aroma.
• Use freshly grated Parmesan for a smooth sauce—pre-shredded can cause clumping.
• Don’t overcrowd the shrimp; cook in batches if needed.
• Taste before serving—Cajun seasoning brands vary in salt levels.
• For a silkier sauce, add a tablespoon of butter at the end.
What to Serve With White Truffle Cajun Shrimp Alfredo
• A crisp arugula salad with lemon vinaigrette
• Garlic bread or toasted baguette
• Roasted asparagus or broccolini
• A chilled glass of Chardonnay or Sauvignon Blanc
When I serve this for guests, I keep the sides simple—the pasta is the statement.
Shelf Life & Storage Tips
Refrigerator: Store in an airtight container for up to 3 days.
Reheating:
Reheat gently on the stovetop with a splash of cream or milk. Avoid microwaving at high heat—it can separate the sauce.
Freezing:
Not recommended. Cream-based sauces tend to separate when thawed.
Frequently Asked Questions

Yes. Just thaw completely and pat dry before seasoning.
