These crab-stuffed portobello mushrooms can do double duty as a fancy starter for a casual dinner party or a light main course on any given night. Meaty and umami-rich portobellos serve as a holder for a light-tasting seafood salad.
Even though the gills of mushrooms are edible, they will darken and discolour everything they touch. Besides, after you scrape out the gills, you’ll have more room for stuffing. And don’t discard the stems; they can be saved and used when making veggie stock.
Per serving:
Preheat oven to 375 F (190 C) and line baking sheet with parchment paper or silicone baking mat.
Remove stems from mushrooms and scrape away the dark gills. Arrange mushrooms on baking sheet, stem side up.
In large bowl, toss together crab, breadcrumbs, red pepper, cheese, shallot, garlic, thyme, lemon juice, mustard, and black pepper. Gently stir in egg. Divide mixture among mushroom caps and bake until crab mixture is set and light golden brown, 12 to 14 minutes. Serve with a few drops of hot sauce, if desired.
