Ingredient Notes & Details

Steak
Use a tender cut like sirloin, ribeye, or New York strip. These cuts stay juicy and cook quickly, making them ideal for steak bites. If you’re meal prepping, sirloin offers great flavor at a more budget-friendly price.

Shell Pasta
Medium shell pasta works best because it traps the Alfredo sauce inside. You can substitute with penne or rotini, but shells give the creamiest bite.

Butter
Use real unsalted butter for better control over seasoning. The butter is key to building flavor for the garlic steak bites.

Garlic
Fresh minced garlic makes a big difference here. Jarred garlic works in a pinch, but fresh gives the sauce that rich, aromatic depth.

Heavy Cream
This is the base of the Alfredo sauce. For best results, avoid substituting with milk—it won’t thicken the same way.

Parmesan Cheese
Freshly grated Parmesan melts smoothly and creates a silky sauce. Pre-shredded cheese may cause graininess.

Olive Oil
A little olive oil helps prevent the butter from burning while searing the steak.

Seasonings
Salt, black pepper, and optional Italian seasoning enhance the natural flavors without overpowering the dish.

Step-by-Step Instructions

Cook the pasta
Bring a large pot of salted water to a boil and cook the shell pasta until just al dente. You want it tender but still firm, as it will finish in the sauce. Drain and set aside.

Prepare the steak
Pat the steak dry with paper towels and cut it into bite-sized cubes. Season generously with salt and pepper on all sides. Dry steak ensures a good sear.

Sear the steak bites
Heat a large skillet over medium-high heat. Add olive oil and half of the butter. Once hot, add the steak bites in a single layer. Do not overcrowd the pan. Sear for 2–3 minutes per side until golden brown. Remove the steak and set aside.

Build the garlic butter base
Lower the heat to medium. Add the remaining butter to the skillet along with minced garlic. Stir constantly for about 30 seconds, just until fragrant. Avoid browning the garlic.

Make the Alfredo sauce
Pour in the heavy cream and stir, scraping up any browned bits from the pan. Let the sauce simmer gently for 3–5 minutes until slightly thickened.

Add the cheese
Reduce heat to low and gradually stir in the grated Parmesan. Keep stirring until the sauce is smooth and creamy.

Combine everything
Add the cooked pasta shells and steak bites back into the skillet. Toss gently until everything is well coated in the garlic butter Alfredo sauce.

Finish and serve
Taste and adjust seasoning as needed. Serve immediately while hot and creamy.
