Ingredients
Scale
- 6 oz (170 g) thin sliced sirloin steaks
- 3 oz (85 g) shredded mild provolone cheese, or cheese of choice
- 4 medium portobello mushrooms, with no cracks
- ¾ cup (180 mL) diced onion
- ¾ cup (180 mL) diced green pepper
- 2 oz (57 g) light cream cheese, softened
- ¼ cup (60 mL) light sour cream
- 2 tbsps light mayonnaise
- 1/8 tsp kosher salt, additional to taste
- Black pepper to taste
- Cooking spray
Instructions
- Preparation: Preheat oven to 400°F and lightly oil a baking sheet to prevent mushroom adhesion during roasting.
- Mushroom Preparation: Carefully remove stems and gills from portobello mushrooms, creating spacious cavities. Brush mushroom tops with oil and season with salt and pepper to enhance roasting potential.
- Protein Treatment: Season sirloin steak, then sear in a scorching skillet for 1-2 minutes per side until perfectly cooked. Slice meat thinly and reserve for further use.
- Vegetable Transformation: In the same skillet, reduce heat and sauté onions and green peppers until soft and translucent, developing a rich flavor foundation.
- Mixture Creation: Combine thinly sliced steak, caramelized onions, sautéed peppers, sour cream, mayonnaise, cream cheese, and shredded cheese in a mixing bowl, blending into a creamy, unified filling.
- Stuffing and Roasting: Distribute filling evenly into mushroom caps, then place on prepared baking sheet. Roast in the oven for 20 minutes until cheese melts completely and mushrooms become tender.
Notes
- Mushroom Prep Tip: Remove stems and gills carefully to create maximum space for delicious filling, ensuring even cooking and better texture.
- Meat Searing Technique: Use high heat for quick 1-2 minute searing, which locks in steak’s juices and creates a beautiful caramelized exterior.
- Cheese Melting Strategy: Distribute filling evenly to guarantee consistent melting and prevent dry or overly saturated spots in the stuffed mushrooms.
- Temperature Control: Maintain 400°F oven temperature to achieve perfect golden-brown tops and ensure mushrooms become tender without becoming watery.
