Equipment Needed
- Large skillet or cast iron pan (12-inch recommended)
- Tongs
- Sharp knife and cutting board
- Meat thermometer (optional)
Ingredients
For the Steak:
- 1.5 lbs sirloin steak, cut into 1-inch cubes (680g)
- 2 tablespoons butter (30g)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon Italian seasoning
For the Garlic Mushrooms:
- 8 oz mushrooms, quartered (226g)
- 4 tablespoons butter (60g)
- 6 cloves garlic, minced
- 1/2 teaspoon paprika (optional)
- Fresh parsley for garnish
Method
- Pat steak cubes completely dry with paper towels.
- Season steak with salt, pepper, and Italian seasoning.
- Heat 2 tablespoons butter in skillet over medium-high heat until bubbling.
- Add steak in batches (don’t overcrowd!) and sear for 2-3 minutes total, turning once.
(Look for a golden-brown crust.)
- Remove steak to a plate, keep warm.
- In the same pan, add remaining butter and mushrooms.
- Cook mushrooms for 3-5 minutes until golden.
(They should release their moisture and start to brown.)
- Add minced garlic, cook for 30 seconds until fragrant.
- Return steak to pan, toss everything in the garlic butter.
- Cook 1-2 minutes more until steak reaches desired doneness.
(130-135°F for medium-rare.)
Crucial Tips
- Room temperature steak sears better.
- Don’t move steak pieces during the first minute of searing.
- Leave space between meat pieces when searing.
- Use high heat – we want to sear, not steam.
Storage & Variations
Storage:
- Refrigerate up to 3 days in an airtight container.
- Reheating: Brief pan-sear or microwave until just warm.
Common Mistakes:
- Overcrowding the pan.
- Oversalting (mushrooms shrink and concentrate flavors).
- Moving meat too much during searing.
Variations:
- Add 1/2 cup heavy cream for a sauce.
- Try different mushroom varieties.
- Add fresh herbs like thyme or rosemary.
- Swap sirloin for ribeye or tenderloin.
Serve With:
- Cauliflower mash
- Zucchini noodles
- Sautéed green beans
This recipe works perfectly for meal prep and doubles easily – just cook in more batches rather than overcrowding your pan. The key to success is getting a good sear on the meat while keeping the inside tender and juicy.
