How to make Crab-Stuffed Portobello Mushrooms
Ingredients:
- 4 large Portobello mushrooms
- 1 cup cooked Dungeness crab meat
- ½ cup cream cheese, softened
- ½ cup shredded mozzarella cheese
- ¼ cup mayonnaise
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 tablespoon Worcestershire sauce
- 1 teaspoon Old Bay seasoning (or seafood seasoning)
- 2 tablespoons fresh parsley, chopped
- Salt and pepper to taste
- Olive oil for brushing
- Optional: lemon wedges for serving
Directions:
-
Prepare the Mushrooms: Start by preheating your oven to 375°F (190°C). Gently clean the Portobello mushrooms with a damp cloth to remove any dirt. Remove the stems and scoop out the gills with a spoon to create more space for the stuffing.

-
Make the Filling: In a large mixing bowl, combine the cooked crab meat, cream cheese, mozzarella cheese, mayonnaise, chopped onion, minced garlic, Worcestershire sauce, Old Bay seasoning, and parsley. Season with salt and pepper. Mix everything together until well combined.
-
Stuff the Mushrooms: Take a spoon and fill each Portobello mushroom cap generously with the crab filling mixture. Make sure to pack it in well.
-
Assemble for Baking: Place the stuffed mushrooms on a baking sheet lined with parchment paper. Brush the tops lightly with olive oil to help them brown.
-
Bake: Bake in the preheated oven for about 20-25 minutes, or until the mushrooms are tender and the filling is bubbly and golden on top.
-
Serve: Remove from the oven and let cool for a few minutes. Serve warm with lemon wedges on the side for an extra burst of flavor.

How to Store Crab-Stuffed Portobello Mushrooms

Avoid microwaving them to keep the texture as good as fresh!
Tips and Mistakes to Avoid
- Use Fresh Crab Meat: If possible, use fresh Dungeness crab meat for the best flavor; canned crab can work in a pinch but may lack the freshness.
- Don’t Overcook: Be mindful of the cooking time. Keep an eye on the mushrooms to avoid them becoming rubbery.
- Pack the Filling: Don’t be shy! Fill the mushrooms well. The more stuffing, the better the flavor.
- Check for Doneness: The filling should be bubbly and slightly golden. If you like a crispier top, broil for the last 2-3 minutes, watching closely.
Variation
There are many delightful variations you can try with this recipe:
- Cheesy Crab Variation: Substitute half of the cream cheese for ricotta cheese for a different texture.
- Spicy Crab Variation: Add diced jalapeños or a splash of hot sauce to the filling for a spicy kick.
- Vegetarian Option: Replace crab with finely chopped broccoli and cheese for a vegetarian version that still captures the essence of the dish.
