Ingredients You’ll Need

What’s truly wonderful about Tasty Crab Stuffed Portobello Mushrooms is how a handful of thoughtful ingredients can create such a gourmet experience. Each element contributes its unique charm—whether it’s the delicate sweetness of crab, the crisp snap of green onions, or the bold kick from Tabasco sauce, every ingredient plays a starring role in the final flavor.

• 1 pound lump crab meat: Fresh or high-quality canned crab provides the sweet, tender seafood foundation that makes this dish shine.
• 3/4 cup panko bread crumbs: These crumbs add a perfect light crunch to the stuffing, helping bind the mixture while keeping it airy.
• 8 green onions, thinly sliced: Both the white and green parts add a subtle oniony brightness that complements the crab’s sweetness beautifully.
• 1 package soft Boursin cheese: This creamy, herbed cheese creates rich moisture and adds luxurious flavor that binds everything together.
• 1 large egg: The egg acts as a natural binder, ensuring the stuffing holds its shape during cooking.
• 1 tablespoon Dijon mustard: A touch of sharpness giving the stuffing complexity without overpowering the crab.
• 1 tablespoon Worcestershire sauce: Adds a savory, umami depth that elevates the overall taste.
• 1 teaspoon Tabasco sauce: Just enough heat to make the filling exciting and bright.
• 4 to 6 large portobello mushroom caps: These meaty mushrooms offer the perfect vessel for the crab stuffing and deliver amazing texture when grilled or baked.

How to Make Tasty Crab Stuffed Portobello Mushrooms

Step 1: Prepare the Crab Filling

Start by gently mixing the lump crab meat, panko bread crumbs, and thinly sliced green onions in a bowl. In a separate bowl, combine the soft Boursin cheese, beaten egg, Dijon mustard, Worcestershire sauce, and Tabasco sauce until smooth and well blended. Fold this creamy mixture into the crab mixture, stirring carefully so the bite-sized crab pieces stay intact. Pop this delicious mixture into the refrigerator to chill while you move on to prepping your mushrooms.

Step 2: Clean and Prepare the Mushrooms

Grab a damp paper towel and gently wipe down those beautiful portobello caps to remove any dirt—no rinsing necessary to avoid sogginess. Carefully pull out the stems with your fingers, then use a spoon to scrape out all the black gills inside, creating ample room for that golden crab stuffing. This little step is key for both presentation and making sure every bite is all about the crab and mushroom harmony.

Step 3: Season the Mushroom Caps

Place the cleaned mushroom caps on a sheet pan. Using a paring knife, pierce several small holes in the center of each mushroom, which helps them cook evenly and prevents sogginess. Then, sprinkle a generous pinch of salt and freshly cracked black pepper inside each cap—this seasoning enhances the mushroom’s natural earthiness, setting the stage perfectly for the crab mixture.

Step 4: Stuff the Mushrooms

Take the cooled crab filling out of the fridge and divide it evenly among the mushroom caps, depending on how many you’re making. Gently press the mixture into each cap without overpacking to keep a tender, airy texture inside. Once stuffed, it’s a great idea to chill the mushrooms briefly to let everything firm up and hold shape during cooking.

Step 5: Cook the Stuffed Mushrooms

Preheat your grill to a high temperature around 450℉ for that gorgeous char and smoky flavor, or your oven to 425℉ if grilling isn’t an option. Place the stuffed mushrooms either on the grate or the baking sheet, cooking for about 15-20 minutes on the grill or 20-30 minutes in the oven. You’re looking for bubbling filling and golden-browned tops. Keep an eye out to avoid flare-ups on the grill, turning the mushrooms gently if needed.

Step 6: Garnish and Serve

Once cooked, transfer the Tasty Crab Stuffed Portobello Mushrooms carefully to a serving platter. A sprinkle of extra chopped scallions adds fresh color and crunch, while a dash of Old Bay seasoning brings a traditional seafood flair. Serve with bright lemon wedges to squeeze over the top, balancing the richness with zesty acidity. These mushrooms are ready to impress and delight any crowd.

Garnishes

A few thoughtful garnishes elevate the dish spectacularly. Besides chopped scallions and Old Bay, try finely chopped fresh parsley or chives for herbal brightness. A drizzle of garlic butter or a sprinkle of smoked paprika can add another subtle layer of flavor, making your presentation just as exciting as the flavors inside.

Side Dishes

Because these stuffed mushrooms are wonderfully rich and satisfying, pairing them with light, crisp side dishes works beautifully. A fresh green salad with vinaigrette, steamed asparagus, or a tangy cucumber salad complement the savory crab stuffing wonderfully. For a heartier meal, roasted baby potatoes or couscous make lovely companions, soaking up any leftover juices.

Creative Ways to Present

For a stunning appetizer, serve the mushrooms on a beautiful wooden board or slate platter, perhaps with a scattering of microgreens or edible flowers for a touch of elegance. Another fun idea is to halve smaller mushrooms, making bite-sized morsels perfect for cocktail parties. If you’re serving them as a main, pile the mushrooms on individual plates alongside vibrant sides and a wedge of lemon for a complete, restaurant-quality experience.

Make Ahead and Storage

Storing Leftovers

If you happen to have any leftovers (and honestly, they rarely last long), store them in an airtight container in the refrigerator. They will keep well for up to 2 days while retaining most of their flavor and texture. Just be mindful that mushrooms might soften slightly after chilling, so reheat carefully.

Freezing

Freezing these stuffed mushrooms isn’t ideal because the texture of both crab meat and mushrooms can change when thawed. However, if you must, freeze them unbaked on a sheet pan first, then transfer to a freezer-safe container. When ready to enjoy, bake them straight from frozen, adding extra cooking time to ensure they are heated through.

Reheating

To reheat your Tasty Crab Stuffed Portobello Mushrooms, the oven is your best friend. Place them on a baking sheet and warm at 350℉ for 10 to 15 minutes or until heated through. Avoid microwaves if possible, since they can make the mushrooms soggy and the crab rubbery. Slow, gentle heat brings back their best flavor and texture.

FAQs

Can I use canned crab meat instead of fresh lump crab?

Absolutely! While fresh lump crab often offers the best texture and flavor, high-quality canned crab can work perfectly fine and is a great budget-friendly option. Just be sure to drain it well to avoid excess moisture.

What can I substitute for Boursin cheese?

If you can’t find Boursin, cream cheese mixed with a bit of garlic powder and fresh herbs like parsley or chives makes a tasty substitute that replicates the creamy texture and herbaceous notes.

Are these mushrooms gluten-free?

They are not gluten-free as written because of the panko bread crumbs. To make this dish gluten-free, substitute panko with gluten-free bread crumbs or crushed gluten-free crackers.

Can I prepare the crab filling in advance?

Yes, the crab filling can be made a day ahead and stored covered in the refrigerator. Chilling allows the flavors to meld beautifully, making your Tasty Crab Stuffed Portobello Mushrooms even more flavorful.

How do I prevent the mushrooms from becoming soggy?

Removing the gills and piercing holes in the mushroom caps helps them release moisture as they cook, reducing sogginess. Also, cooking at higher temperatures will help evaporate excess moisture quickly.
