- 1 cup Gruyere Cheese (shredded): Melts beautifully to create a gooey, golden topping that complements the crab perfectly.
- ¼ teaspoon Garlic Powder: A hint of warmth and depth that rounds out the savory profile.
- 1 teaspoon Old Bay Seasoning: Classic seafood seasoning that adds a subtle kick without overpowering the natural flavors.

How to Make Crab Stuffed Mushrooms Recipe
Step 1: Prepare the flavorful filling
Begin by combining the finely chopped onion, red bell pepper, half a cup of shredded Gruyere cheese, garlic powder, and Old Bay seasoning in a mixing bowl. Stir these ingredients gently to blend the sweetness of the veggies with the cheesy and slightly spicy accents. This mixture lays the foundation for the delicious crab filling to come.
Step 2: Incorporate the crab meat
Carefully fold in the crab claw meat to the seasoned vegetable mixture, taking care not to break up the delicate crab chunks too much. Season the mixture with salt and pepper to taste, balancing the flavors so that every bite bursts with zest and freshness. This step ensures that the crab remains the star while being perfectly complemented by the other ingredients.
Step 3: Fill the mushroom caps
Gently spoon the crab mixture into the hollowed-out mushroom caps, packing each one generously. Arrange the stuffed mushrooms on a lined baking sheet, prepping them for their final transformation. This part is especially fun because you get to see the dish come together visually and smell those wonderful flavors starting to mingle.
Step 4: Add a cheesy, crispy topping
Sprinkle the remaining shredded Gruyere cheese over the stuffed mushrooms, followed by a generous dusting of seasoned panko breadcrumbs. This topping is going to bake into a golden, crispy layer that adds a gorgeous texture contrast to the creamy filling and tender mushrooms underneath.
Step 5: Bake to perfection
Place the baking sheet in a preheated oven at 350 degrees Fahrenheit and bake the mushrooms for 20 to 30 minutes. Keep an eye out for the mushrooms to be cooked through and the topping to turn a beautiful golden brown. This step brings all the flavors and textures together, creating a mouthwatering appetizer that’s impossible to resist.
Step 6: Serve immediately
Once baked to perfection, remove the mushrooms from the oven and transfer them to a serving platter. These Crab Stuffed Mushrooms Recipe bites are best enjoyed hot, while the cheese is melty and the mushrooms are at their tender best. Get ready for lots of compliments and requests for seconds!
How to Serve Crab Stuffed Mushrooms Recipe
Garnishes
A simple garnish of finely chopped fresh parsley or chives adds a burst of color and a hint of herbal brightness that lifts the rich flavors of the crab and cheese. A light squeeze of fresh lemon juice just before serving can also bring a zesty freshness that complements the seafood beautifully.
Side Dishes
These stuffed mushrooms make an elegant starter alongside a crisp green salad or a light seafood-inspired pasta. For parties, a chilled white wine like Sauvignon Blanc or a sparkling Rosé pairs wonderfully with the savory and creamy qualities of the dish.
Creative Ways to Present
For a fun twist, serve each mushroom on small individual spoons or on a wooden board with some fresh lemon wedges and a drizzle of garlic butter. You can also place them on a bed of mixed greens to add height and visual appeal to your appetizer table. Presentation is a great way to add a wow factor to this already delicious Crab Stuffed Mushrooms Recipe.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store them in an airtight container in the refrigerator. They will stay fresh for up to two days, although they’re so good fresh that it’s hard to resist finishing them all in one go!
Freezing
While freezing stuffed mushrooms is possible, the delicate texture of the crab and mushrooms may suffer after thawing. If you do freeze them, wrap the individually stuffed but uncooked mushrooms tightly in plastic wrap, then place in a sealed freezer bag for up to one month. Bake them from frozen, adding a few extra minutes to the cooking time.
Reheating
To reheat, warm the stuffed mushrooms in a preheated oven at 350 degrees Fahrenheit for about 10-15 minutes, until heated through and the cheese is bubbling again. Avoid microwaving as it can make the mushrooms watery and the cheese uneven.
FAQs
Can I use different types of mushrooms for this recipe?
Absolutely! While white button mushrooms are the classic choice, you can try cremini or baby portobello mushrooms for a deeper flavor. Just ensure they’re large enough to hold the filling.
Is it okay to use canned crab meat?
Fresh or lump crab meat is ideal for the best texture and flavor, but canned crab meat can be used in a pinch. Drain it well before mixing to avoid excess moisture in your stuffing.
Can I make this recipe vegetarian?
To make a vegetarian version, you can substitute the crab with finely chopped artichoke hearts or hearts of palm. Season well to maintain the rich, savory notes of the dish.
What if I don’t have Gruyere cheese?
Gruyere offers a nutty, melty finish, but Swiss, fontina, or mozzarella can work as alternatives. Choose cheeses that melt well for the best results.
How spicy is this recipe?
The Old Bay seasoning gives a gentle kick and a complex flavor without overwhelming heat, making it approachable for most palates. You can adjust the amount based on your spice preference.

This Crab Stuffed Mushrooms Recipe is one of those dishes that effortlessly elevates any occasion, blending simple ingredients into a sophisticated and satisfying treat.
