Garlic Butter Sirloin Stroganoff with Mushrooms

Tender sirloin tips braised in a savory garlic butter sauce with caramelized onions, mushrooms, and a silky half-and-half finish. This classic stroganoff balances rich, umami flavors from the beef and sherry with bright garlic and fresh parsley. Serve over egg noodles or rice for a comforting weeknight dinner that feels special enough for guests. The two-stage butter method ensures both the vegetables and meat get maximum flavor while keeping the steak tender.

Tips
Don't skip the two-stage cooking: separating the butter keeps vegetables tender while allowing the steak to develop color without overcooking.
Slice mushrooms evenly and don't crowd the skillet during the 4-minute cook for proper browning rather than steaming.
Use dry sherry; cream sherries are too sweet and will unbalance the savory sauce.
Good to Know
Cover and refrigerate up to 3 days. Reheat gently on stovetop with splash of broth to restore sauce consistency.
Prepare garlic butter mixture and slice vegetables 1 day ahead. Cook stroganoff up to the sherry addition, cool, and refrigerate. Warm through before finishing with half-and-half.
Serve immediately over buttered egg noodles or rice with an arugula salad or steamed green beans.
Common Mistakes
Don't skip salt and pepper on the sirloin before cooking to avoid bland meat.
Don't skip the constant stirring during the 5-minute steak cook to avoid uneven doneness and tough edges.
Don't use cream-based sherry to avoid overly sweet sauce that masks beef and garlic flavors.

FAQ
Can I use frozen mushrooms?
Thaw and pat dry thoroughly first; frozen mushrooms release excess water when cooked directly, leading to steaming instead of browning. Reduce cook time by 1-2 minutes since they're already softened.
What if I don't have sherry wine?
Dry white wine or beef broth work as one-to-one swaps. Skip alcohol if needed, but broth adds less depth than sherry. Adding 1/2 teaspoon Worcestershire sauce compensates for umami loss.
How long can I keep leftovers?
Covered and refrigerated, up to 3 days. Freezing is not recommended due to cream separation, though the sauce may be salvageable with vigorous whisking during reheating.
