What You’ll Need
To create these delicious Crab-Stuffed Portobello Mushrooms, gather the following ingredients:
- 4 portobello mushroom caps (3-1/2 to 4" diameter)
- 8 oz lump crabmeat (fully-cooked, pasteurized)
- 1/2 cup panko crumbs
- 2 tablespoons chopped sweet onion
- 1 or 2 cloves garlic (minced)
- 1 teaspoon fresh thyme leaves (or 1/4 teaspoon dried)
- 1-1/2 tablespoons freshly squeezed lemon juice (from 1/2 lemon)
- 2/3 cup shredded Muenster or Monterey Jack cheese (divided)
- 1 egg (lightly beaten)
- Salt and freshly ground black pepper
- Lemon wedges (for serving)
How to Make Crab-Stuffed Portobello Mushrooms
Let’s create this cozy dish together! Follow these easy steps:
-
Pre-bake the Portobello Mushroom Caps: Preheat your oven to 375°F (190°C). Remove the stems from the portobello caps and gently wipe the tops with a damp cloth. Place the caps on a baking sheet, stem side up, and bake for about 10 minutes until they start to soften. This not only enhances their flavor but also helps prevent excess moisture in the stuffing.
-
Prepare the Crab Stuffing: In a mixing bowl, combine the lump crabmeat, panko crumbs, chopped sweet onion, minced garlic, fresh thyme, lemon juice, and 1/3 cup of the shredded cheese. Gently fold in the beaten egg, and season with salt and freshly ground black pepper. The mixture should be moist with a slightly crumbly texture.
-
Stuff, Bake, and Serve: Once your mushrooms are ready, generously fill each cap with the crab mixture. Top each stuffed mushroom with the remaining cheese, giving it a lovely golden finish as it bakes! Return the mushrooms to the oven and bake for an additional 15–20 minutes until they are bubbly, golden, and irresistible. Serve warm with lemon wedges on the side for that extra zing!
Delicious Variations to Try
- Mediterranean Twist: Add chopped sun-dried tomatoes and Kalamata olives for a zesty flavor and a pop of color.
- Spicy Kick: Mix in diced jalapeños or drizzle with a spicy aioli after baking for a fiery touch.
- Cheesy Delight: Substitute the Muenster or Monterey Jack cheese with a rich Brie or creamy goat cheese for an indulgent twist.
- Herb Infusion: Experiment with fresh herbs like basil or dill instead of thyme for a fresh seasonal flavor.
My Best Kitchen Secrets
- Make-Ahead Advice: Prepare the crab stuffing and stuff the mushrooms a few hours ahead of baking. Store them covered in the refrigerator until you’re ready to pop them in the oven.
- Ingredient Swaps: If you can’t find lump crabmeat, feel free to use imitation crab for a more budget-friendly option. It will still taste delightful!
- Storage Suggestions: Leftovers can be stored in an airtight container in the fridge for up to three days. Just reheat gently in the oven for best results.
