Ingredients You’ll Need

For the Blackened Seasoning

• 1 tbsp smoked paprika

• 1 tsp garlic powder

• 1 tsp onion powder

• 1 tsp dried oregano

• 1 tsp dried thyme

• 1 tsp cayenne pepper (adjust for spice preference)

• 1 tsp black pepper

• 1 tsp kosher salt

For the Steak & Shrimp

• 1 lb sirloin or ribeye steak (about 1-inch thick)

• 1 lb large shrimp, peeled and deveined

• 2 tbsp olive oil or melted butter

For the Alfredo Sauce

• 3 tbsp unsalted butter

• 3 cloves garlic, minced

• 1 ½ cups heavy cream

• 1 cup freshly grated Parmesan cheese

• ½ cup grated Pecorino Romano (optional for extra richness)

• Salt & freshly cracked black pepper to taste

• Pinch of nutmeg (optional but recommended)

For Serving

• 12 oz fettuccine pasta (or pasta of choice)

• Fresh parsley, chopped

• Extra Parmesan for garnish

Step-by-Step Instructions

1. Cook the Pasta

Bring a large pot of salted water to a boil. Add your pasta and cook until al dente (tender but still slightly firm in the center). Drain and set aside, reserving about ½ cup of the pasta water.

2. Prepare the Blackened Seasoning

Mix together paprika, garlic powder, onion powder, oregano, thyme, cayenne, black pepper, and salt in a small bowl. This creates a smoky-spicy rub that will coat both the steak and shrimp.

3. Season the Steak and Shrimp

Rub the steak generously on all sides with most of the blackened seasoning. Toss the shrimp with the remaining seasoning and drizzle of olive oil so they are evenly coated.

4. Cook the Steak

Heat a cast-iron skillet over medium-high heat and drizzle with oil. Once the pan is hot, sear the steak for about 4–5 minutes on each side for medium-rare (adjust to preferred doneness). Transfer steak to a plate, tent loosely with foil, and let it rest for 5 minutes. After resting, slice against the grain into thin strips.

5. Cook the Shrimp

In the same skillet, add the shrimp. Cook for 1–2 minutes per side until they’re pink and opaque. Be careful not to overcook, as shrimp cook quickly. Set aside.

6. Make the Alfredo Sauce

In a large saucepan or skillet, melt the butter. Sauté garlic for 1 minute until fragrant. Add the heavy cream and simmer for 3–4 minutes, letting it thicken slightly. Stir in Parmesan and Romano (if using) until smooth and creamy. Add salt, pepper, and a pinch of nutmeg for extra depth.

7. Combine and Serve

Toss the al dente pasta in the Alfredo sauce, adding a splash of reserved pasta water if needed. Plate generously, then top with sliced blackened steak and shrimp. Garnish with fresh parsley and extra Parmesan.

Tips for the Best Blackened Steak and Shrimp Alfredo

• Use cast iron for best results: It delivers a flavorful crust on the steak and cooks shrimp evenly.

• Don’t skip resting the steak: It keeps the juices inside, ensuring tender slices.

• Grate your own cheese: Pre-shredded Parmesan contains anti-caking agents that prevent melting smoothly. Freshly grated cheese gives the sauce its signature creamy texture.

• Adjust the spice level: Use less cayenne if you prefer mild heat, or add extra if you like it fiery.

• Finish pasta in the sauce: Tossing pasta directly in Alfredo ensures every bite is coated.

Variations to Try

• Chicken instead of steak: Swap steak for blackened chicken breast for a lighter option.

• Seafood-heavy version: Use scallops, crab, or lobster tail along with the shrimp.

• Vegetarian twist: Replace proteins with roasted veggies like mushrooms, zucchini, or bell peppers.

• Different pasta shapes: Try penne, linguine, or rigatoni instead of fettuccine.

• Spicy Cajun Alfredo: Mix in additional Cajun or Creole spices to intensify the flavor.

What to Serve With Blackened Steak and Shrimp Alfredo

This dish is rich and indulgent, so lighter and fresher sides work best:

• A crisp Caesar salad or simple garden salad

• Garlic bread or toasted baguette slices

• Roasted asparagus, broccoli, or green beans

• A chilled glass of Sauvignon Blanc, Chardonnay, or even a bold Cabernet Sauvignon for steak lovers

Frequently Asked Questions

Can I make Alfredo sauce ahead of time?
Yes, but it’s best served fresh. If reheating, add a splash of cream or milk to keep it from drying out.

Can I adjust the thickness of the sauce?
Absolutely. Add a little pasta water for a looser sauce, or simmer longer for a thicker consistency.

Can I grill the steak instead of pan-searing?
Yes, grilling works great and adds a smoky char. Just avoid overcooking.

How long does this dish keep?
Store in the fridge for up to 3 days in an airtight container. Reheat gently with added cream.

Can I freeze it?
Freezing Alfredo is not ideal, as cream-based sauces tend to separate. For best results, enjoy it fresh.

Nutritional Insights

This dish is indulgent, but with balance, it can fit into many diets. The proteins from steak and shrimp add satiety, while Parmesan provides calcium. For a lighter twist, you can substitute half-and-half for cream or use zoodles/spaghetti squash instead of pasta.
