Storage Tips
Store leftovers in an airtight container in the refrigerator for up to three days. Reheat gently in a pan or air fryer to preserve texture and flavor. Avoid microwaving as it can make the steak tougher.
Ingredient Substitutions
If fresh parsley or cilantro is not available use dried herbs or a squeeze of fresh lemon juice to brighten the dish. Steak cuts like ribeye or sirloin both work well choose one with good marbling for juiciness. Button mushrooms can be swapped with cremini or shiitake for different flavor profiles.
Serving Suggestions
Serve over steamed rice or cauliflower rice for a complete meal. Pair with a crisp green salad or sautéed greens to add freshness and balance richness. A drizzle of extra melted butter or a squeeze of fresh lemon can elevate the final dish.
