Ingredients
Scale
Pasta
- 8 ounces penne pasta
Shrimp
- 1 pound large shrimp, raw, deveined, tail removed
- 1 teaspoon blackened seasoning
- 1 tablespoon vegetable oil
Steak
- 1 pound top sirloin steak, cut into 1-inch cubes
- 1 teaspoon blackened seasoning
- ¼ cup (½ stick / 57 g) unsalted butter
Sauce
- 1 small yellow onion, diced (about ½ cup)
- 2 teaspoons garlic, minced
- 2 cups (476 g) heavy whipping cream
- 2 cups (200 g) parmesan cheese, freshly grated
- 1 tablespoon blackened seasoning
- ½ teaspoon kosher salt
- ½ teaspoon black pepper
- parsley, chopped for garnish
Instructions
- Cook Pasta: Bring a large pot of salted water to a boil over medium-high heat. Add penne pasta and cook al dente according to package directions. Reserve 1 cup of pasta water then drain the rest and set the pasta aside.
- Prepare Shrimp: Season the shrimp evenly with 1 teaspoon of blackened seasoning. Heat 1 tablespoon of vegetable oil in a large 13-inch skillet over medium heat. Once hot, add the shrimp and cook for 1-2 minutes per side until opaque and cooked through. Transfer shrimp to a plate and tent with foil to keep warm.
- Cook Steak: Season the steak cubes evenly with 1 teaspoon of blackened seasoning. Increase heat to high and add ¼ cup unsalted butter to the skillet. Let the butter melt and start to bubble. Add the steak cubes and cook for 1-2 minutes per side until browned on the outside but still pink inside. Transfer the steak to the plate with shrimp and tent to keep warm.
- Make Sauce: Reduce skillet heat to medium. Add the diced yellow onion and cook until softened, about 3-5 minutes. Add the minced garlic and cook for 1 minute until fragrant. Pour in 2 cups heavy whipping cream, ¼ to ½ cup reserved pasta water, 2 cups freshly grated parmesan cheese, 1 tablespoon blackened seasoning, ½ teaspoon kosher salt, and ½ teaspoon black pepper. Stir continuously until the cheese melts and the sauce thickens slightly.
- Toss Pasta with Sauce: Add the cooked penne noodles back into the skillet and toss to coat evenly with the Alfredo sauce. Add more pasta water as needed to achieve the desired consistency.
- Plate and Serve: Top the creamy pasta with the cooked shrimp and steak cubes. Garnish with chopped parsley and serve immediately for the best flavor and texture.
Notes
- Blackened seasoning can be homemade or store-bought; adjust to taste for spiciness.
- For a creamier sauce, use full-fat heavy cream and fresh parmesan.
- Do not overcook the steak to maintain tenderness and juiciness.
- Reserve pasta water to help thin the sauce without losing flavor.
- Serve immediately as the sauce thickens upon standing.
