Ingredients

Scale
  • 🧄 For the Stuffed Mushrooms

    • 4 large Portobello mushrooms

    • 1 lb lobster meat, chopped

    • 1/2 cup breadcrumbs

    • 1/4 cup mayonnaise

    • 2 tbsp lemon juice

    • 1 tsp Old Bay seasoning

    • 1/4 cup shredded Gruyère

    • 2 tbsp chopped chives


Instructions

  • Preheat the Oven
    Preheat your oven to 375°F (190°C) and line a baking sheet with foil or parchment paper.

  • Prepare the Mushrooms
    Gently remove the stems and gills from the Portobello mushrooms to make room for the stuffing.

  • Mix the Filling
    In a bowl, combine lobster meat, breadcrumbs, mayonnaise, lemon juice, Old Bay, Gruyère, and chives. Mix until fully blended.

  • Stuff the Mushrooms
    Spoon the filling into each mushroom cap, pressing gently so the filling stays in place.

  • Bake
    Place stuffed mushrooms on the baking sheet and bake for 18–20 minutes, until the tops are golden.

 

  • Optional Broil
    For a crispy finish, broil the mushrooms for an additional 1–2 minutes.

Notes

  • Use fresh lobster for the best flavor, or thaw frozen lobster meat thoroughly and pat dry.

  • Substitute Gruyère with fontina or white cheddar if desired.

  • Add a pinch of cayenne for a spicy kick.

  • This dish pairs beautifully with crisp white wine or Champagne.

  • Pre-bake mushroom caps for 5–7 minutes to reduce sogginess.
