I could eat Crab Stuffed Mushroom filling the way other people eat raw cookie dough: cold, unbaked, and by the spoonful. But once that easy, cheesy filling is baked to golden, bubbly perfection in a mushroom cap? It’s game over.

Speaking of games, this easy appetizer recipe is ideal as part of your tailgate spread or holiday buffet. They’re easy enough for a weeknight (prep time is a mere 15 minutes!) yet elegant enough for a special occasion. I hate to play favorites but Crab Stuffed Mushrooms rank among my personal top 10 Culinary Hill recipes ever. Bet you can’t eat just one!

Recipe ingredients

Labeled ingredients for crab stuffed mushrooms.

At a Glance: Here is a quick snapshot of what ingredients are in this recipe.
Please see the recipe card below for specific quantities.

Ingredient notes

  • Cream cheese: You’ll need 4 ounces, or half of a “brick,” for this recipe. Put the rest to delicious use in a half batch of Cream Cheese with Pepper Jelly, Cream Cheese Frosting, or Cream Cheese Wontons.
  • Italian Seasoning: From a store-bought spice blend, or to make your own Italian Seasoning, in a small bowl, combine 2 tablespoons of dried basil, 2 tablespoons of dried oregano, 2 tablespoons of dried rosemary, 2 tablespoons of dried thyme, and 2 tablespoons of dried marjoram. This recipe only calls for 1 teaspoon, so store extra in in an airtight container.
  • Imitation crab meat: Also labeled as crab sticks, krab sticks, imitation crab, or seafood sticks, this is white fish mixed with binders and seasonings and pressed into stick form to resemble the flavor and texture of crab. Find it in the seafood department at most major supermarkets.
  • Shredded mozzarella cheese: This melts like a dream and I love its flavor in Crab Stuffed Mushrooms. Monterey Jack or Parmesan also work well. 
  • Baby portobello mushrooms: Or white button mushrooms. Just be sure to clean whichever you choose (more tips about how to clean mushrooms below) and remove the stems.

Step by step instructions

  1. Preheat oven to 350 degrees. Line a baking sheet with parchment paper or foil for easy cleanup. In a medium bowl, combine cream cheese, sour cream, garlic, and Italian seasoning. Stir in crab meat, scallions, and mozzarella cheese, then season to taste with salt and pepper (I like ½ teaspoon salt and ¼ teaspoon pepper). You will have about 2 cups filling.

Recipe tips and variations

  • Yield: This stuffed mushroom recipe makes about 16 pieces, enough for 8 servings, 2 pieces each. You will have more or fewer servings depending on the size of your baby portobello mushrooms.
  • Storage: Store leftovers covered in the refrigerator for up to 4 days.
  • Make ahead: Make the filling 1 day in advance and refrigerate until you’re ready to stuff the mushrooms.

Recipe FAQs

Can I wash mushrooms?

Yes! I don’t recommend submerging them in water for an extended period of time, but a quick rinse and a spin in a salad spinner is a great, America’s-Test-Kitchen-approved way to clean mushrooms. You can also wipe them down with a clean, damp kitchen towel if you prefer to clean mushrooms that way.

What should I do if all of the filling doesn’t fit inside my mushrooms?

Mushroom sizes vary, so you may have some extra. Enjoy it scooped up with crudites or spread on crackers or baguette slices.

  1. Love the stuffing best I have made and I have tried many. This recipe is so easy. Added a dash of Tabasco and topped with melted butter mixed with panko bread crumbs and broiled last few minutes to brown.5 stars

    1. Thanks Terri, that topping sounds delicious I’ll have to try it next time I make these! – Meggan

  2. I love these stuffed crab mushrooms! I used the large portobello mushrooms (3 1/2” across) so I had to bake them for about 40 minutes. They did end up sitting in a pool of water/juice, so I put them on a wire rack and baked them for another 5 minutes. Voila! No soggy mushrooms.

  3. Here is another crab dip recipe

    Cream cheesr softened
    Sour cream
    Diced onion not to much maybe 1/4 cup
    Dill seeds i like a couple of teaspoons
    Salt
    Pepper
    I dont measure i just put together. Mix together then add about or almost 1 lb. Of real dungeons crap thats been pick though. I like to rinse my crap with cold water then put in cheese cloth to squeeze out water. Put in small casserole dish and bake about 350f. 30 to 45 minute or untill bubbles and golden brown. Goes great with cocktail rye bread or crackers or stuff mushrooms.
