This hearty garlic butter steak bites and potatoes recipe brings restaurant-quality flavor to your dinner table in just 20 minutes. The combination of tender steak cubes and crispy potatoes, all coated in aromatic garlic butter, creates a satisfying one-pan meal that feels both indulgent and effortless.
I developed this recipe during a particularly busy week when I needed a quick but impressive dinner. My family was so enthusiastic about the results that it's now in our regular rotation for both weeknight dinners and casual entertaining.
Ingredients
- Olive oil: creates the initial searing base without burning like butter would alone
- Unsalted butter: adds rich flavor while allowing you to control salt levels
- Yukon Gold potatoes: hold their shape while getting creamy inside look for firm potatoes without sprouts
- Fresh garlic: minced just before cooking releases maximum flavor
- Dried rosemary and oregano: provide aromatic Mediterranean flavors that complement beef perfectly
- Kosher salt: has a cleaner flavor than table salt and adheres better to the meat
- Fresh ground pepper: adds essential spice and depth
- Sirloin steak: offers excellent flavor and tenderness without breaking the budget choose bright red meat with some marbling
- Fresh parsley: optional but adds color and a fresh finishing note
Step-by-Step Instructions
- Prepare the Cooking Base:
- Heat your cast iron skillet over medium high heat until it feels hot when you hold your hand a few inches above the surface. Add olive oil and 2 tablespoons butter, allowing them to fully melt and start to shimmer. The combination prevents burning while maximizing flavor development.
- Cook the Potatoes:
- Add your diced potatoes along with garlic, herbs, salt, and pepper. Let them sit undisturbed for 4 minutes to develop a golden crust. This patience creates the perfect texture contrast. Stir once and continue cooking for another 3 4 minutes until they yield easily to a fork. Remove and set aside, keeping them warm.
- Sear the Steak:
- Return your skillet to high heat a very hot pan is crucial for proper searing. Add remaining butter and allow it to melt completely. Arrange steak cubes in a single layer without overcrowding. Cook undisturbed for 1 minute to develop a flavorful crust, then flip or stir for just 1 2 additional minutes until desired doneness. The quick cooking keeps the meat tender and juicy.
- Combine and Serve:
- Remove skillet from heat to prevent overcooking. Return potatoes to the pan and gently toss everything together, allowing the flavors to meld. Taste and adjust seasoning if needed. The residual heat will continue cooking the ingredients slightly. Finish with fresh parsley for a burst of color and brightness.

I particularly love the combination of rosemary and beef in this recipe. It reminds me of Sunday dinners at my grandmother's house, where she would always insist that a proper steak needed "just enough herbs to complement, never compete with, the meat itself."
Perfect Pairings
This hearty dish stands beautifully on its own, but for a complete meal, consider serving it with a simple green salad dressed with lemon vinaigrette. The acidity helps cut through the richness of the meat and potatoes. For special occasions, a glass of medium bodied red wine like Merlot or Cabernet Sauvignon complements the beef perfectly.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to three days. For best results when reheating, warm the mixture in a skillet over medium heat rather than microwaving. Add a small pat of butter to refresh the sauce and prevent dryness. The flavors often develop overnight, making day two equally delicious.
Ingredient Substitutions
This recipe welcomes adaptation based on what you have available. Ribeye or tenderloin can replace sirloin for a more luxurious meal. Red skinned or fingerling potatoes work beautifully in place of Yukon Gold. For a lighter version, try using half the butter and supplementing with beef broth for moisture. Fresh herbs can replace dried by doubling the amount called for.
Troubleshooting Tips
If your potatoes are browning too quickly before becoming tender, reduce heat and add a splash of water with a lid for steam finishing. When cooking steak, resist the urge to constantly flip the pieces one or two turns is sufficient for proper searing. Allow meat to rest at room temperature for 15 minutes before cutting for the juiciest results.
