Portobello mushrooms are nature’s burger buns, pizza crusts, and now—stuffing vessels. This recipe takes the meaty, umami-rich caps and fills them with a simple mix of cheese, garlic, and breadcrumbs. It’s vegetarian comfort food that actually satisfies. Twenty minutes, one pan, zero regrets.
Step-by-Step Instructions

1
Prep the Mushrooms
- Preheat oven to 400°F (200°C).
- Gently wipe mushrooms clean with a damp paper towel. Don’t rinse them—they soak up water like sponges.
- Remove stems (save for another use or chop into the filling).
- Using a spoon, scrape out the dark gills if desired (optional, but prevents dark liquid).

Storage Notes
Store leftovers in an airtight container for up to 3 days. Reheat in a 375°F oven for 5-7 minutes (microwave makes them soggy). These are not freezer-friendly—the mushrooms become watery when thawed.
