Ingredients

• 4 large portobello mushroom caps, stems and gills removed
• 2 tbsp olive oil (for mushrooms)
• 1/4 tsp salt (for mushrooms)
• 1/4 tsp black pepper (for mushrooms)
• 1 lb (450 g) thinly sliced ribeye steak (or sirloin)
• 1 tbsp olive oil (for filling)
• 1 small yellow onion, thinly sliced
• 1 small green bell pepper, thinly sliced
• 1 small red bell pepper, thinly sliced
• 2 cloves garlic, minced
• 1/2 tsp salt (for filling)
• 1/4 tsp black pepper (for filling)
• 1/2 tsp smoked paprika (optional)
• 1 cup (100 g) shredded provolone or mozzarella cheese

Instructions

Step 1

Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.

Step 2

Brush mushroom caps on both sides with olive oil. Sprinkle with salt and pepper. Place them gill-side up on the prepared baking sheet and roast for 10 minutes.

Step 3

While mushrooms roast, heat 1 tbsp olive oil in a large skillet over medium-high heat. Add onion and bell peppers; sauté for 4–5 minutes until softened.

Step 4

Add garlic and cook for 1 minute. Push vegetables to the side of the skillet.

Step 5

Add sliced steak, season with salt, pepper, and smoked paprika. Cook, stirring, until just browned, about 3–4 minutes. Mix steak and vegetables together. Remove from heat.

Step 6

Remove mushrooms from oven. Drain any liquid from the caps.

Step 7

Fill each mushroom cap with the steak and pepper mixture. Top evenly with shredded cheese.

Step 8

Return to oven and bake for an additional 8–10 minutes, until cheese is melted and bubbly.

Step 9

Serve hot, garnished with fresh parsley if desired.

Zusatztipps für die Zubereitung

To ensure the mushrooms don't become soggy, be sure to drain any accumulated liquid from the caps after the initial roasting step. Slicing the ribeye against the grain while it is slightly frozen can help you achieve the paper-thin slices typical of a great Philly cheesesteak.

Varianten und Anpassungen

You can easily substitute the ribeye with thinly sliced chicken breast or use the chopped mushroom stems in the filling for a vegetarian version. If you enjoy a bit of heat, add some sautéed jalapeños to the vegetable mixture.

Serviervorschläge

These stuffed mushrooms are a meal on their own but pair wonderfully with a simple arugula salad or a side of roasted broccoli. Garnish with fresh parsley for a pop of color and freshness.
