Key Ingredients
- Lump Crab Meat - Lump crab meat gives these stuffed mushrooms the best texture because it stays tender and slightly chunky after baking instead of disappearing into the filling. During testing, I found that gently folding the crab into the cream cheese mixture helped keep the larger pieces intact and prevented the filling from becoming dense or overly mashed.
- Baby Portobello Mushrooms - Baby portobello mushrooms, also called cremini mushrooms, work especially well here because they are sturdy enough to hold the filling without collapsing during baking. Removing the brown gills from the inside cavity made a noticeable difference during testing and helped keep the mushrooms from becoming overly watery. If you want to turn this into more of a main course, full-sized portobello mushrooms work beautifully and I just double the filling for them.
- Cream Cheese - The cream cheese creates a rich filling that helps bind the crab mixture together while keeping the mushrooms creamy and flavorful. I found that allowing the cream cheese to fully soften before mixing created a much smoother filling and distributed the crab more evenly throughout the mushrooms.

Variations
- Lighten up - if you want to lighten up the crab-stuffed mushrooms you can substitute half the cream cheese for Greek yogurt or use a low-fat cream cheese.
- Savory flavor - if you want to amp up the savory flavor of the mushrooms, sprinkle in some chopped, cooked bacon to the cream cheese mixture. You can also add sauteed fresh spinach, some chopped green onion, onion powder, or pine nuts for crunch.
- Cheese - you can substitute vegan cream cheese in this recipe or even nutritional yeast. If you are not a fan of parmesan cheese, add cheddar cheese instead.

How To Make Crab Stuffed Portobello Mushrooms:
Step 1: Preheat the oven to 400 degrees Fahrenheit.
Prepare the mushrooms by removing the mushroom stems, cleaning any dirt off the mushroom caps, and using a small paring knife or spoon to remove the brown gills inside the mushroom cavities.
Step 2: In a mixing bowl, combine the crabmeat, cream cheese, shallot, parsley, and parmesan cheese until smooth.
Melt the butter in the microwave and stir the panko into it.
Step 3: Prepare a baking sheet by greasing it with olive oil or using parchment paper and then greasing the paper. Lay the mushrooms on the baking sheet and fill the caps with the cream cheese filling.
Top each mushroom with panko and then sprinkle them with parmesan cheese.
Step 4: Bake for 20 minutes until the top is golden brown.
Sprinkle the mushrooms with the remaining parsley and enjoy.
Gwen's Pro Tips
When you're removing the stems, save and freeze them for soup!
When cleaning your mushrooms, don't rinse them! This makes them soggy. Instead, use a damp paper towel to wipe away the dirt.
To help prevent the mushrooms from getting soggy, make sure to remove the brown gills from the inside of the mushrooms. You can also place the mushrooms on a wire rack over the sheet pan so that the juices are separated when baking.
Crab Stuffed Portobello Mushrooms FAQ's
Baby portobello mushrooms, also called cremini mushrooms, are ideal for stuffing because they hold their shape well and have a deeper savory flavor than white mushrooms. For a larger main-course version, full-sized portobello mushrooms work beautifully too or use the Grilled Portobello Mushroom recipe and stuff the mushrooms after grilling.
To remove dirt from your mushrooms, use a damp paper towel and wipe away the dirt. Mushrooms absorb water easily so rinsing them will cause them to become soggy.
Rubbery stuffed mushrooms normally occur when the mushrooms have absorbed too much liquid. To prevent this, make sure not to rinse your mushrooms when cleaning them. Also, bake them on a wire rack over top of a baking tray. This way, their juices drain away from the mushrooms and they don't get that rubbery texture.
