Step 1

Preheat your oven to 375° and prepare a baking sheet by lining it with aluminum foil or parchment.

Step 2

Place the portobello mushrooms hollow side up on your prepared baking sheet.

Step 3

Bake the mushrooms for 8 minutes to help release moisture before stuffing them.

Step 4

In a medium mixing bowl, combine the cream cheese, jalapeño, garlic, salt, and pepper.

Step 5

Stir in ½ cup of the shredded cheddar.

Step 6

Spoon ¼ of the cheese and jalapeño mixture into each of the portobello caps, then top with the remaining ½ cup of cheddar.

Step 7

Place the stuffed portobellos into the oven and bake for 12-15 minutes, or until the cheese is melted and lightly golden-brown.

Step 8

Serve your portobellos on a bun with avocado, lettuce, tomato, or whatever toppings you desire.
