How to Make Blackened Steak and Shrimp Alfredo
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Cook the penne pasta until al dente, according to package directions. Reserve about 1 cup of pasta water, then drain the pasta and set aside.
💡 Tip: Pasta water adds starch to the sauce, helping it cling beautifully to the pasta.
Step 2: Sauté the Shrimp
Season the shrimp with 1 teaspoon blackened seasoning. In a large skillet over medium-high heat, add ½ tablespoon vegetable oil and sear the shrimp for about 1-2 minutes per side or until opaque and slightly charred. Remove and set aside.
Step 3: Sear the Steak
Season steak cubes with 1 tablespoon blackened seasoning. In the same skillet, heat the remaining ½ tablespoon vegetable oil and sear the steak pieces until browned on all sides (about 2–3 minutes per side). Remove and set aside.
🔥 Shortcut: You can marinate the shrimp and steak in the seasoning up to 4 hours ahead to deepen the flavor.
Step 4: Make the Alfredo Sauce
In the same skillet, melt ¼ cup butter. Add diced onion and cook for 2–3 minutes until translucent. Stir in the minced garlic and cook for another 30 seconds until fragrant.
Pour in the heavy whipping cream and about ½ cup reserved pasta water. Stir, then gradually add the Parmesan cheese, whisking constantly. Once melted, season the sauce with salt, pepper, and a little extra blackened seasoning to taste. Let the sauce simmer and thicken for 3–5 minutes.
Step 5: Combine and Serve
Add the cooked pasta to the sauce and stir to coat. Top with blackened shrimp and steak, and garnish with freshly chopped parsley.
💡 Optional Add-Ons: Add spinach, sun-dried tomatoes, or mushrooms for extra depth.
Storage and Reheating Tips
Storing Leftovers:
Transfer leftovers to an airtight container and refrigerate for up to 3 days.
Reheating:
To reheat, add a splash of cream or milk to a skillet and gently rewarm over medium heat to loosen the sauce. Stir occasionally to keep it smooth. Avoid microwaving for too long, as shrimp can become rubbery.
🧊 Freezing Not Recommended: Alfredo sauces with cream and cheese don’t freeze well—they tend to separate upon thawing.
Recipe Variations and Swaps
-
Protein Swap: Use chicken breast or scallops in place of shrimp or steak.

Drink and Food Pairings
Wine Pairings:
-
White: A buttery Chardonnay or oaked Viognier complements the creaminess and spice.

Garlic bread or buttery breadsticks
-
Caesar salad or a crisp arugula salad with lemon vinaigrette

Roasted asparagus or steamed broccoli for some green on the plate
Frequently Asked Questions (FAQ)
Can I make this dish ahead of time?
Yes, you can prepare the steak and shrimp ahead, as well as the sauce. Reheat and combine just before serving to maintain the best texture.
Is it spicy?
The blackened seasoning gives it a smoky, slightly spicy flavor. You can control the heat by using less seasoning or a milder blend.
Can I use pre-cooked shrimp?
Yes, but cook them only briefly to warm through and avoid overcooking, which can make them rubbery.
What is blackened seasoning made of?
Typically a mix of paprika, cayenne, garlic powder, onion powder, oregano, thyme, salt, and pepper. You can use store-bought or make your own.
How do I keep the sauce from breaking?
Use gentle heat and add cheese gradually while stirring constantly. Avoid boiling once the cheese is added.
