Ingredients
Scale
Main Proteins:
- 6 ounces (170 grams) thin sliced sirloin steaks
- 3 ounces (85 grams) shredded mild provolone cheese, or cheese of your choice
Vegetables and Aromatics:
- 4 medium portobello mushrooms, with no cracks
- ¾ cup (180 milliliters) diced onion
- ¾ cup (180 milliliters) diced green pepper
Dairy and Seasoning:
- 2 ounces (57 grams) light cream cheese, softened
- ¼ cup (60 milliliters) light sour cream
- 2 tablespoons light mayonnaise
- 1/8 teaspoon kosher salt, additional to taste
- Black pepper to taste
- Cooking spray
Instructions
- Preheat the oven to 400°F and lightly coat a baking sheet with oil to prevent sticking during cooking.
- Carefully remove stems and gills from portobello mushrooms, creating a spacious cavity for filling. Lightly coat mushroom tops with oil and season with salt and pepper to enhance roasting.
- Season sirloin steak with salt and pepper, then sear in a hot skillet for 1-2 minutes per side until perfectly cooked. Slice the meat thinly and set aside.
- Using the same skillet, reduce heat and sauté onions and green peppers until they become soft and translucent, developing a rich base flavor.
- In a mixing bowl, blend the thinly sliced steak, caramelized onions, sautéed peppers, sour cream, mayonnaise, cream cheese, and shredded cheese into a creamy, cohesive mixture.
- Evenly distribute the prepared filling into the mushroom caps, ensuring each mushroom receives approximately 1/2 cup of the savory mixture.
- Place stuffed mushrooms on the prepared baking sheet and roast in the oven for 20 minutes, or until the cheese melts completely and the mushrooms become tender.
Notes
- Prep ahead by slicing steak and chopping vegetables to streamline cooking process.
- Store leftover ingredients separately in airtight containers for quick future meal assembly.
- Swap sirloin with flank or ribeye for varied texture and enhanced meat flavor profiles.
