How to Make Blackened Steak and Shrimp Alfredo
Step 1: Cook the Pasta
Begin by bringing a large pot of salted water to a boil. Add the penne pasta and cook according to package instructions until al dente. Drain and set aside.
Step 2: Season the Shrimp
In a bowl, toss the raw shrimp with 1 teaspoon of blackened seasoning until they are well coated.
Step 3: Sear the Shrimp
Heat vegetable oil in a skillet over medium-high heat. Add the seasoned shrimp and cook for about 2-3 minutes on each side until they turn pink and opaque. Remove from skillet and set aside.

In the same skillet, add the cubed top sirloin steak with another teaspoon of blackened seasoning. Sear for about 4-5 minutes until browned on all sides but still juicy inside. Remove from skillet.

Reduce heat to medium. In the same skillet, melt butter. Add diced onions and sauté until translucent, about 3-4 minutes. Stir in minced garlic and cook for an additional minute.
Step 6: Combine Ingredients
Slowly whisk in heavy whipping cream and bring to a gentle simmer. Stir in grated parmesan cheese until melted and smooth. Season with remaining blackened seasoning, salt, and pepper.

Common Mistakes to Avoid
When making Blackened Steak and Shrimp Alfredo, it’s easy to overlook some key steps. Here are common mistakes to watch out for.
- Incorrect seasoning application: Applying the blackened seasoning too lightly can lead to bland flavors. Ensure you coat the shrimp and steak generously for a bold taste.
- Overcooking the shrimp: Cooking shrimp for too long can make them rubbery. Cook just until they turn pink and opaque, usually about 2-3 minutes per side.
- Skipping fresh ingredients: Using pre-grated cheese or stale garlic can dull the dish’s flavor. Always opt for freshly grated parmesan and fresh garlic for the best results.
- Neglecting pasta timing: Adding pasta at the wrong time can affect its texture. Make sure you cook it al dente and combine it with the sauce immediately for optimal creaminess.
- Not adjusting sauce thickness: If your sauce is too thick, it may not coat the pasta well. Add a bit of reserved pasta water to adjust consistency while mixing.
Refrigerator Storage
- Store in an airtight container.
- Keeps well for up to 3 days in the refrigerator.
Freezing Blackened Steak and Shrimp Alfredo
- Use freezer-safe containers or bags.
