- ¼ teaspoon Garlic Powder: Offers a mild garlic aroma without overpowering the other flavors.
- 1 teaspoon Old Bay Seasoning: A classic seafood seasoning that lifts the crab mixture to the next level.

How to Make Crab Stuffed Mushrooms Recipe
Step 1: Prepare the Crab Mixture
Start by combining the finely chopped onion and red bell pepper in a bowl with half a cup of shredded Gruyere cheese. Sprinkle in the garlic powder and Old Bay seasoning, then stir everything together until it’s evenly blended. This mixture forms the flavorful base of your stuffing, balancing savory, sweet, and mildly spiced notes.
Step 2: Add the Crab Meat
Gently fold in the crab claw meat, trying not to break it up too much to keep those desirable chunks intact. Season with salt and pepper according to your preference, tasting as you go. This step ensures the crab stays front and center, beautifully paired with the other ingredients.
Step 3: Stuff the Mushrooms
Carefully spoon the crab mixture into each mushroom cap, packing them generously. Place the stuffed mushrooms on a baking sheet lined with parchment or foil for easy cleanup. The mushrooms act as perfect edible vessels for the rich filling.
Step 4: Add Cheese and Breadcrumb Topping
Sprinkle the remaining half-cup of Gruyere over the stuffed mushrooms, then finish with a generous dusting of seasoned panko breadcrumbs. This topping will create a satisfyingly crunchy layer that contrasts wonderfully with the creamy crab filling beneath.
Step 5: Bake to Perfection
Bake in a preheated 350°F oven for 20 to 30 minutes. You’ll know they’re done when the mushrooms are tender and the cheese is bubbly and golden. The aroma filling your kitchen at this point is enough to make anyone’s mouth water!
Step 6: Serve Immediately
Once baked, remove the Crab Stuffed Mushrooms Recipe from the oven and serve right away. This dish is best enjoyed warm, while the cheese is melty and the breadcrumbs still crisp, offering a delightful mix of textures and flavors.
How to Serve Crab Stuffed Mushrooms Recipe
Garnishes
To elevate your Crab Stuffed Mushrooms, sprinkle some freshly chopped parsley or chives on top before serving. A squeeze of lemon juice can add a bright, zesty freshness that complements the richness of the filling perfectly. These simple touches take the presentation up a notch and balance the flavors beautifully.
Side Dishes
This appetizer pairs wonderfully with crisp green salads, garlic butter pasta, or even a bowl of chilled tomato bisque. The freshness and acidity of these sides thoughtfully cut through the richness of the crab and cheese, rounding out the meal in a satisfying way.
Creative Ways to Present
For a memorable party presentation, arrange the stuffed mushrooms on a large slate or wooden board with lemon wedges on the side. Pair with colorful dipping sauces like garlic aioli or a light remoulade for guests to customize each bite. Another idea is to serve them on small lettuce cups, adding a refreshing crunch and making them super easy to grab and enjoy.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store the cooled Crab Stuffed Mushrooms in an airtight container in the refrigerator. They will keep well for up to two days, maintaining much of their flavor and texture when stored properly.
Freezing
Freezing cooked Crab Stuffed Mushrooms is possible but not ideal, as the texture of the mushrooms may change upon thawing. If you do choose to freeze, place them on a tray to freeze individually first, then transfer to a freezer-safe container. Use within one month for best quality.
Reheating
Reheat leftovers in an oven preheated to 350°F for about 10 minutes or until warmed through. Avoid microwaving if possible to maintain the breadcrumb topping’s crispness and the filling’s creaminess.
FAQs
Can I use a different type of mushroom for this recipe?
Absolutely! While white button mushrooms work best due to their size and texture, cremini or baby bella mushrooms can also be used for a deeper flavor. Just make sure they’re cleaned and have their stems removed to create enough space for the crab stuffing.
Is it okay to use canned crab meat?
Yes, canned crab meat can be used in a pinch, but fresh or lump crab claw meat will give you the best texture and flavor. If you use canned, drain well to avoid making the filling too watery.
Can I prepare the stuffed mushrooms ahead of time before baking?
Definitely! You can assemble the mushrooms and store them covered in the refrigerator for up to a day. Just add the breadcrumb topping right before baking to keep it crisp and fresh.
What can I substitute for Gruyere cheese?
If Gruyere is not available, Swiss cheese or mozzarella can be good alternatives that melt well and provide a mild, creamy flavor. However, Gruyere’s distinctive nutty notes are truly special in this recipe.
How spicy is the Old Bay seasoning in this dish?
Old Bay offers a gentle warmth and a classic seafood spice blend rather than intense heat. It enhances the crab’s flavor beautifully without making the dish spicy-hot, so this recipe is approachable for most palates.
