What Cut of Steak Should I Use for Garlic Butter Steak Bites?

For the most tender, flavorful steak bites, go for sirloin, tenderloin, or ribeye. These cuts offer a perfect balance of juiciness and marbling. Sirloin is budget-friendly and holds its shape well when seared, while tenderloin is buttery soft. Ribeye brings robust flavor to the plate. Make sure to cut the steak into even-sized cubes for uniform cooking.

Ingredients for the Garlic Butter Steak Bites & Loaded Cheddar Alfredo Shells

Steak Bites:

Steak (Sirloin, Tenderloin, or Ribeye): The star of the dish. These cuts sear beautifully and stay tender.
Garlic: Freshly minced garlic infuses the butter with aromatic, savory depth.
Butter: Unsalted butter helps brown the steak and builds the rich garlic coating.
Olive Oil: Helps the butter from burning while searing.
Salt & Pepper: Essential for bringing out the flavor of the steak.
Fresh Parsley: For a pop of color and a hint of herbaceous balance.

Cheddar Alfredo Shells:

Pasta Shells: Perfect for catching all that luscious sauce inside their folds.
Heavy Cream: The foundation for a rich and creamy Alfredo base.
Cream Cheese: Adds extra silkiness and a slight tang.
Garlic Powder: A mellow garlic layer that enhances the sauce.
Cheddar Cheese (Sharp): Bold cheesy flavor that makes these shells loaded.
Parmesan Cheese: Brings nutty, salty complexity to the Alfredo.
Paprika: Adds a mild kick and a splash of color.
Chopped Parsley: For garnish and freshness.

How To Make the Garlic Butter Steak Bites & Loaded Cheddar Alfredo Shells

Step 1: Prep the Steak

Start by cutting your steak into 1-inch cubes. Pat them dry with a paper towel to ensure a nice sear. Season generously with salt and pepper.

Step 2: Sear the Steak Bites

Heat olive oil in a large skillet over medium-high heat. Sear the steak cubes in batches, giving them space to develop a golden-brown crust. Cook each batch for 2–3 minutes per side until desired doneness. Remove and set aside.

Step 3: Make the Garlic Butter

Reduce the heat to medium. Add butter and minced garlic to the skillet. Stir until the garlic is fragrant, about 1 minute. Return the steak bites to the skillet, tossing to coat in the garlic butter. Sprinkle with chopped parsley.

Step 4: Boil the Pasta Shells

While the steak cooks, bring a large pot of salted water to a boil. Add the pasta shells and cook according to package instructions until al dente. Drain and set aside.

Step 5: Prepare the Loaded Cheddar Alfredo Sauce

In a saucepan over medium heat, add heavy cream, cream cheese, and garlic powder. Whisk until the cream cheese is fully melted and smooth. Stir in sharp cheddar and Parmesan, allowing the cheeses to melt into a creamy sauce.

Step 6: Combine Pasta & Sauce

Toss the cooked pasta shells into the Alfredo sauce. Stir gently until well coated. Sprinkle with paprika and extra parsley for a pop of color.

Serving and Storing Garlic Butter Steak Bites & Loaded Cheddar Alfredo Shells

Serve the garlic butter steak bites hot, right next to a generous scoop of cheddar Alfredo shells. If you’re feeling fancy, garnish with extra parsley and a pinch of paprika.

To store leftovers, place the steak and pasta in separate airtight containers. They’ll keep in the fridge for up to 3 days. Reheat gently on the stovetop or microwave, adding a splash of cream or broth to loosen the sauce if needed.
