How to Make Creamy Garlic Steak Shells

Step 1: Prepare and Cook the Pasta

Start by bringing a large pot of salted water to a boil. Cook your pasta shells according to the package directions until al dente. Drain, rinse briefly to stop cooking, and set aside.

Tip: Reserve ½ cup of pasta water to adjust the sauce later if needed.

Step 2: Season and Sear the Steak

  1. In a bowl, combine the cubed steak with Worcestershire sauce, garlic powder, onion powder, salt, pepper, and optional smoked paprika.

  2. Heat a tablespoon of olive oil in a large skillet over medium-high heat.

  3. Once hot, add the steak cubes in a single layer. Avoid overcrowding.

  4. Sear the steak for about 2-3 minutes per side until browned and cooked to your desired doneness (medium is ideal for juicy bites).

  5. Transfer the steak to a plate and set aside.

Step 3: Make the Creamy Garlic Sauce

  1. In the same skillet, lower the heat to medium.

  2. Add the butter. Once melted, stir in the minced garlic and sauté for 30 seconds until fragrant.

  3. Sprinkle the flour over the butter and garlic, whisking constantly to form a roux. Cook for 1 minute to eliminate any raw flour taste.

  4. Slowly pour in the heavy cream while whisking to prevent lumps.

  5. Add the Parmesan cheese, Italian seasoning, red pepper flakes (if using), salt, and black pepper.

  6. Let the sauce simmer gently for 3–5 minutes until thick and creamy. Stir frequently.

Tip: If the sauce is too thick, loosen it with a few tablespoons of the reserved pasta water.

Step 4: Combine Everything

  1. Add the drained pasta shells to the skillet with the sauce.

  2. Stir to coat the shells in the creamy garlic goodness.

  3. Return the seared steak bites to the skillet and gently toss to combine.

  4. Cook for an additional 2 minutes to heat everything through and allow the flavors to meld.

Step 5: Serve and Garnish

Plate the Creamy Garlic Steak Shells hot, sprinkled with chopped parsley for a fresh burst of color and flavor. Optionally, garnish with extra Parmesan and a twist of black pepper.

Tips for Success

Steak Tips:

  • Cut against the grain for tender bites.

  • Let the steak rest after searing to retain juices.

  • Use a tender cut like sirloin, ribeye, or even filet mignon for best results.

Sauce Tips:

  • Use freshly grated Parmesan for better melting and flavor.

  • Stir sauce frequently to prevent scorching.

  • Don’t overcook the sauce after adding cheese to avoid graininess.

Pasta Tips:

  • Salt the pasta water well—it should taste like the sea.

  • Don’t overcook the pasta; shells should retain some bite.

Ingredient Variations

  • Protein Swaps: Try chicken, shrimp, or even mushrooms for a vegetarian option.

  • Pasta Alternatives: Penne, rigatoni, or fusilli work beautifully too.

  • Add-ins: Baby spinach, sun-dried tomatoes, or sautéed mushrooms are excellent additions.

Storage and Reheating

Storage:

  • Refrigerate leftovers in an airtight container for up to 3 days.

Reheating:

  • Reheat on the stovetop with a splash of cream or milk to loosen the sauce.

  • Microwave in short intervals, stirring between each, to avoid drying out the steak.

Make-Ahead Tips

  • You can prep the steak and sauce separately and store them up to a day in advance.

  • Reheat and combine just before serving for a quick dinner.

  • Red Wine like Cabernet Sauvignon or Merlot
