Steps to Create Your Crab Stuffed Portobello Mushrooms

1. Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup.
2. Brush the Portobello mushroom caps with 1 tablespoon of olive oil on both sides. Sprinkle lightly with salt and pepper. Place them gill side up on the baking sheet and roast for 10 minutes to soften and release some moisture.
3. While the mushrooms roast, prepare the crab filling. In a medium bowl, combine the cream cheese, mayonnaise, lemon juice, Dijon mustard, and Old Bay seasoning. Mix until smooth and creamy.
4. Fold in the crab meat, green onions, red bell pepper, and minced garlic. Taste and adjust seasoning with salt and pepper if needed. The filling should be flavorful but not overpowering.
5. Remove the mushrooms from the oven. Spoon the crab mixture generously into each cap, pressing lightly to fill the cavities.
6. Sprinkle the tops with shredded mozzarella or Parmesan cheese if using. Drizzle the remaining tablespoon of olive oil over the stuffed mushrooms for a golden finish.
7. Return the baking sheet to the oven and bake for another 15-18 minutes, or until the cheese is bubbly and the mushrooms are tender but not soggy.
8. Remove from oven and let cool for a few minutes. Garnish with fresh parsley before serving.

Tips for Making the Best Crab Stuffed Portobello Mushrooms

One of my favorite memories in the kitchen is watching family members gather around a dish like this—everyone eager to dive in, but also appreciating the care that went into those simple ingredients. Here are a few tips I’ve learned along the way that help make this dish shine every time:

• Pick the right mushrooms: Choose firm, large Portobello caps with no bruises. Their meaty texture is key to holding the filling and balancing the crab’s delicate flavor.
• Don’t skip removing the gills: The dark gills can release excess moisture and turn your mushrooms soggy. Use a spoon to gently scrape them out before roasting.
• Use fresh lump crab meat: It really makes a difference. Avoid canned crab for this recipe unless you’re in a pinch—fresh or pasteurized crab has a sweeter, cleaner flavor.
• Let your cream cheese soften: This makes mixing easier and creates a smooth, creamy filling that holds together well.
• Season thoughtfully: The Old Bay seasoning adds that classic seafood touch, but if you love a bit of heat, add a pinch of cayenne or smoked paprika for a smoky kick.
• Watch your bake time: Overcooked mushrooms can get bitter and mushy, so keep an eye on them as they roast and bake with filling.

Serving Suggestions and Pairings

We often serve these Crab Stuffed Portobello Mushrooms as a main course on their own, paired with a crisp green salad dressed with lemon vinaigrette. On more festive occasions, I like to bring out some garlic roasted potatoes or a light couscous salad to round out the meal. One of my favorite touches is a chilled glass of Sauvignon Blanc, which complements the seafood flavors beautifully. Learn more: BowTie Pasta with Mushrooms, Spinach, and Onions

When my family gathers around the table, these mushrooms always spark conversation and smiles. They’re elegant enough for guests but easy enough for a weeknight dinner when you want to show love without fuss.

Storage and Reheating Tips

Like many dishes born from my busy life as a mom and wife, these stuffed mushrooms are perfect for making ahead. After baking, allow them to cool completely, then store in an airtight container in the refrigerator for up to 2 days.

To reheat, place the mushrooms on a baking sheet and warm them in a preheated oven at 350°F (175°C) for about 10-12 minutes until heated through. Avoid microwaving if you want to keep the mushroom texture intact—oven reheating keeps everything tender and delicious.

If you want to prepare the filling in advance, you can mix it up to a day ahead and refrigerate it separately. Stuff the mushrooms just before baking for maximum freshness.
