Steak and Shrimp Alfredo tops silky butter-and-cheese penne with Cajun ribeye cubes and quickly seared shrimp. Instead of a flour-thickened cream sauce, hot pasta melts room-temperature butter while Romano, Parmesan, and reserved pasta water form the coating.

The recipe serves 4 in 60 minutes, including 15 minutes of preparation and 45 minutes of cooking. Steak and shrimp cook separately so each protein receives its proper timing.

For the steak, use exactly 2 whole ribeye steaks cut into cubes, 2 tablespoons Cajun seasoning, and melted beef tallow as needed. Separately, use 1 pound peeled and deveined large shrimp, another 2 tablespoons Cajun seasoning, and melted beef tallow as needed.

The Alfredo pasta needs 16 ounces penne, ½ cup room-temperature unsalted butter, ½ cup freshly grated Romano, ½ cup freshly grated Parmesan, and chopped fresh chives for garnish. Reserve about 2 ounces pasta water before draining.

Grilled Cajun ribeye cubes and shrimp served over rich, creamy alfredo pasta made with Romano and Parmesan cheeses.

Ingredients You'll Need

  • Steak

  • Shrimp

  • Alfredo Pasta

How to Make It

1.

1. Season the Proteins: In one bowl, toss the cubed ribeye with beef tallow and Cajun seasoning until well coated. In another bowl, do the same with the shrimp, coating them evenly with tallow and seasoning.

2.

2. Heat the Grill: Fire up your grill to high heat, around 400°F. Make sure the grates are clean and ready for cooking.

3.

3. Cook the Steak: Place the seasoned steak cubes on the hot grill and cook for 3-4 minutes, turning as needed to get a nice sear on all sides. Cook to your preferred doneness, then remove and let rest.

4.

4. Cook the Shrimp: Heat a cast iron skillet on the grill with a bit of beef tallow. Add the seasoned shrimp and cook for 1-2 minutes until they turn pink and are cooked through. Remove and keep warm.

5.

5. Prepare the Pasta: Cook the penne pasta according to package directions until al dente. Before draining, save about 2 ounces of the starchy pasta water. Drain the pasta and set aside.

6.

6. Create the Alfredo Base: Place the room temperature butter in the center of your serving bowl and flatten it out. Add the hot pasta on top and toss it around to melt the butter and coat the noodles.

7.

7. Finish the Alfredo: Sprinkle the Romano and Parmesan cheeses over the pasta, then add the reserved pasta water. Toss everything together until you get a silky, creamy sauce that coats each noodle.

8.

8. Assemble and Serve: Top the creamy pasta with the grilled steak and shrimp. Sprinkle with fresh chopped chives for color and flavor, then serve immediately while everything is hot.
