Ingredients for the Cajun Steak Bites with Cheesy Garlic Shell Pasta Skillet

Steak (Sirloin or Ribeye): The star protein, chosen for its tenderness and sear potential.
Shell Pasta: Its shape holds all the cheesy garlic sauce for a delicious bite.
Heavy Cream: Builds the base of the rich, creamy cheese sauce.
Cheddar Cheese (Sharp): Melts into the sauce for bold cheesy flavor.
Garlic (Freshly Minced): Adds a pungent, aromatic backbone to the sauce.
Cajun Seasoning: Infuses the steak with spicy, smoky flavor.
Salted Butter: Used to sear the steak and enrich the sauce.
Parmesan Cheese (Grated): For nutty, salty balance in the cheese sauce.
Olive Oil: Helps achieve a golden sear on the steak.
Parsley (Optional): Fresh garnish to brighten the finished dish.

How To Make the Cajun Steak Bites with Cheesy Garlic Shell Pasta Skillet

Step 1: Cook the Pasta

Boil shell pasta in salted water until al dente. Drain and set aside. Reserve 1/2 cup of pasta water.

Step 2: Season and Sear the Steak

Toss steak cubes in Cajun seasoning and a splash of olive oil. Heat a cast iron skillet over medium-high heat, then sear steak bites for 2–3 minutes per side until browned. Remove and set aside.

Step 3: Build the Cheese Sauce

In the same skillet, reduce heat to medium. Add butter and minced garlic, cooking until fragrant. Stir in heavy cream and pasta water. Once simmering, whisk in cheddar and parmesan until melted and smooth.

Step 4: Combine and Toss

Add cooked pasta shells to the cheese sauce and stir to coat. Return steak bites to the skillet and fold everything together.

Step 5: Garnish and Serve

Top with chopped parsley and an extra sprinkle of parmesan or Cajun spice for presentation.

Serving and Storing This Cajun Steak Skillet

This dish is best served hot and fresh out of the skillet, while the cheese is perfectly melted and the steak bites are juicy and crisp. It’s a meal on its own, but pairs well with a crisp green salad or roasted veggies.

To store leftovers, place in an airtight container and refrigerate for up to 3 days. When reheating, add a splash of milk or cream to bring the sauce back to life. Avoid microwaving too long to prevent the steak from overcooking.
