Sirloin Steak Tips
Choosing the right sirloin steak is key to this recipe’s success. Look for cuts that are bright red with fine marbling of fat, which helps keep the meat tender and juicy while cooking. When preparing your steak cubes, be sure to pat them thoroughly dry with paper towels before seasoning. Removing surface moisture allows the steak to sear properly, developing a golden crust instead of steaming. If you can, buy your sirloin from a trusted butcher who can cut it fresh to size for you. This step will help the steak cook evenly in your skillet. Finally, try to let the meat come to room temperature for about 15 minutes before cooking to ensure even doneness.
Options for Substitutions
- Swap sirloin steak for ribeye or filet mignon cubes for a richer or more tender texture.
- Use button mushrooms or portobello slices instead of cremini mushrooms.
- Replace unsalted butter with ghee or avocado oil for a dairy-free option.
- Swap fresh rosemary and thyme for dried herbs, but reduce the amount by half since dried herbs are stronger.
- Use garlic powder if fresh garlic is unavailable, adding it in the last minute of cooking.
- Garnish with fresh cilantro or basil instead of parsley for a different herbal note.
Watch Out for These Mistakes
One common mistake is not drying your steak cubes well enough before seasoning. When there’s moisture on the surface, the meat tends to steam rather than sear, which means you lose that appetizing crust. Be patient and thoroughly pat the cubes dry with paper towels.
Another pitfall is overcrowding the skillet during searing. When cubes are too close together, they release moisture that prevents browning. To avoid this, sear your steak in batches if needed, giving each cube enough room to caramelize properly on all sides.
Be careful about when you add garlic and herbs to the skillet. Adding them too early can cause garlic to burn, which creates a bitter taste. Stir these aromatics just for about a minute after the mushrooms are cooked, so their flavors stay fresh and fragrant.
Finally, avoid reheating the leftovers too quickly or at too high a temperature. Steak can become tough if overcooked during reheating. Gently warm it in a skillet with a splash of water or broth on low heat to maintain tenderness.

What to Serve With Garlic Butter Steak Bite Mushroom Skillet?
This skillet pairs wonderfully with mashed potatoes, which soak up all the buttery sauce. If you prefer something lighter, steamed rice is another excellent choice that balances the dish. Crusty bread is perfect for dipping and rounding out the meal. For a veggie side, simple sautéed green beans or a fresh garden salad offer a nice, crisp contrast.
Storage Instructions
Store: Keep leftovers in an airtight container in the refrigerator. For best flavor and texture, consume within 3 days.
Freeze: This dish can be frozen for up to 2 months. Use a freezer-safe container, thaw overnight in the refrigerator before reheating.
Reheat: To reheat, place the skillet contents in a pan over low heat. Add a small splash of water or broth and stir gently until warmed through. Avoid high heat to keep steak tender. Alternatively, microwave on medium power in short intervals, stirring in between.

Ingredients
- 1.5 lbs sirloin steak, cut into 1-inch cubes
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 2 tbsp olive oil
- 5 tbsp unsalted butter, divided
- 8 oz cremini mushrooms, sliced
- 5 cloves garlic, minced
- 1 tbsp fresh rosemary, chopped
- 1 tbsp fresh thyme leaves
- 2 tbsp fresh parsley, chopped, for garnish

Step-by-Step Instructions
Step 1: Season the Steak Cubes
Start by patting the sirloin steak cubes dry using paper towels. This step is important for a good sear. Then sprinkle the kosher salt and black pepper evenly over the cubes to season them well.
Step 2: Sear the Steak
Heat the olive oil and 2 tablespoons of butter in a large cast iron skillet over high heat until it shimmers. Place the steak cubes in a single layer, working in batches if necessary to avoid overcrowding. Let them sear without moving for 2 to 3 minutes to develop a golden crust. Flip the cubes and sear on the other side for about 2 more minutes for medium doneness. Transfer the seared steak bites to a plate.
Step 3: Cook the Mushrooms
In the same skillet, lower heat to medium and add the remaining 3 tablespoons of butter. Add the sliced cremini mushrooms and cook for 5 to 6 minutes. Keep stirring occasionally until the mushrooms turn a deep golden brown and most of the liquid has evaporated.
Step 4: Add Garlic and Herbs
Stir in the minced garlic, chopped rosemary, and fresh thyme leaves. Cook everything together for about 1 minute until you can smell the fragrant garlic and herbs without burning.
Step 5: Combine Steak and Finish Cooking
Return the steak bites to the skillet along with any juices on the plate. Toss everything to coat the steak and mushrooms well with the herb garlic butter. Cook for 1 to 2 minutes more to reheat the steak and blend the flavors together.
Step 6: Serve and Garnish
Sprinkle fresh chopped parsley over the dish for a burst of color and fresh flavor. Serve hot with mashed potatoes, rice, or crusty bread to enjoy every bit of the delicious sauce.
