How to Make Crab-Stuffed Portobello Mushrooms
Step 1: Prepare the Mushroom Caps
Start by preheating your oven to 375°F (190°C). While that’s warming up, clean the portobello caps with a damp cloth and remove the stems. This step is important because it allows more room for that delicious stuffing! Afterward, lightly brush both sides with olive oil and season with salt and pepper. This will help enhance their natural flavors during baking.
Step 2: Make the Filling
In a mixing bowl, combine the lump crabmeat, panko crumbs, chopped onion, minced garlic, thyme leaves, lemon juice, half of the shredded cheese, and the beaten egg. Season with salt and pepper to taste. Mixing well ensures that every bite is packed with flavor. Plus, using fresh ingredients makes all the difference!
Step 3: Stuff the Mushrooms
Carefully spoon the crab mixture into each mushroom cap. Don’t be shy—fill them generously! Top each stuffed mushroom with the remaining shredded cheese for that irresistible melted goodness on top.
Step 4: Bake Until Golden
Arrange your stuffed mushrooms on a baking sheet lined with parchment paper. Bake them in your preheated oven for about 25 minutes or until they are golden brown and bubbling. The aroma will fill your kitchen—trust me; it’s hard to wait!
Step 5: Serve Warm
Once they’re done baking, let them cool slightly before serving. A squeeze of fresh lemon juice over each stuffed mushroom adds that final touch of brightness. Serve these beauties warm alongside lemon wedges for an extra burst of flavor.
Enjoy every bite of these amazing Crab-Stuffed Portobello Mushrooms! They’re sure to become a cherished recipe in your home just like they are in mine.
Pro Tips for Making Crab-Stuffed Portobello Mushrooms
Creating the perfect crab-stuffed portobello mushrooms is a breeze with these handy tips!
- Choose fresh mushrooms: Opt for firm, plump portobello caps that are free from blemishes. Fresh mushrooms have a better flavor and texture, enhancing the overall dish.
- Drain crabmeat thoroughly: Ensure that your lump crabmeat is well-drained before mixing it with other ingredients. Excess moisture can make the stuffing soggy, while properly drained meat helps maintain a delightful texture.
- Customize the cheese: Feel free to experiment with different types of cheese! While Muenster and Monterey Jack work beautifully, cheeses like Gouda or even a sprinkle of Parmesan can add unique flavors to the stuffing.
- Don’t skip the lemon juice: The acidity from fresh lemon juice brightens up the flavors in this dish. It cuts through the richness of the cheese and crab, making each bite refreshing and delicious.
- Bake until golden: Keep an eye on your mushrooms while they bake! A golden-brown top indicates that your stuffing is perfectly cooked and ready to be enjoyed.

- Mixed Green Salad: A light salad with mixed greens, cherry tomatoes, and a zesty vinaigrette provides a refreshing contrast to the rich flavors of the mushrooms.
- Garlic Bread: Crispy garlic bread serves as a wonderful accompaniment for soaking up any leftover juices on your plate while adding a comforting touch.
- Roasted Asparagus: Simply roasted asparagus drizzled with olive oil and seasoned with salt makes for a tasty, nutritious side that pairs well with the seafood flavors.
