Crab stuffed mushrooms are a wonderful appetizer for absolutely any occasion. They’re fancy enough to serve for a special occasion or a holiday party, but it’s also simple enough for a weeknight family dinner. Tender mushrooms are stuffed to perfection with a mixture that features crab meat, parmesan cheese, garlic, and more! It truly is like taking a little bite of heaven from all of the complimentary flavors and textures.
It’s a great appetizer for a crowd and you can easily double the recipe as needed. When I’m preparing for a larger group, I almost always double this recipe! For the best results, try to get portobello mushrooms that are close to the same size and ones that are not too small or too large. Although, you can use smaller mushrooms to create a one-bite appetizer but make sure to get more of them in that case.
These stuffed mushrooms are really very easy to make with simple ingredients in just under an hour from start to finish. This is a reliable recipe that you can count on, so don’t be afraid to whip up a big batch just before the party starts. If your friends and family are anything like mine, you’ll watch these crab stuffed mushrooms disappear with a quickness!
Portobello Mushrooms – Try to pick out mushrooms that look nice and firm, no dark and soft spots. Don’t discard the stems! You’ll need them for the filling.
Crab Meat – You can use claw or lump crab meat, either will work just fine. SIFT THORUGH the crab meat thoroughly with your hands because there are always pieces of crab shell left behind.
Cream Cheese – I recommend using a full fat cream cheese for the best results. Remember to let it soften to room temperature prior to using!
Parmesan Cheese – Freshly grated parmesan cheese is the way to go for both superior flavor and consistency.
Bread Crumbs – you can also use gluten free bread crumbs if you need to make gluten free stuffed mushrooms.

PRO TIP: When working with crab, always spread the crab meat out and sift through it to find leftover shells. 90% of the time you will find some shells.
How To Make Crab Stuffed Mushrooms
Prepare the mushrooms: Rinse whole mushrooms under cold water and gently pat them dry with a paper towel. Carefully pop off the mushrooms stems, right where it connects to the cap.
Cook the veggies: Preheat a pan with 1 TBSP of olive oil over medium-high heat. Sauté the diced mushroom stems and diced onion until they begin to caramelize. Press the garlic into the onion/mushroom mixture and sauté just until fragrant. Add the cooked veggies to a mixing bowl.
Check your crab meat: Sift through the crab meat thoroughly with your fingers to make sure there are no pieces of shells accidentally left behind! Then, add crab meat to the mixing bowl.
Create the filling: Add all of the remaining ingredients for the filling to the mixing bowl and mix very well until it’s all combined.
Stuff the mushrooms: Set the mushroom caps in a slightly greased baking dish, cup side up. Generously fill each cap with stuffing mixture, pressing down lightly with your finger to fit a little bit more.
Bake: Sprinkle with some parmesan cheese over the top of stuffed mushrooms, then bake at 375°F for 20 minutes.
This recipe isn’t naturally gluten-free, but it can easily be made that way!
Simply substitute breadcrumbs for gluten–free breadcrumbs and increase the amount slightly. Add an extra 1 or 2 tablespoons of gluten-free bread crumbs since they are not as dense as regular bread crumbs.
There have been a couple of occasions where I had some stuffing leftover. It all depends on the size of mushrooms and how much stuffing you can fit into them. If you want to make sure to use up all the filling, you can get an extra pack of mushrooms when shopping for the ingredients, just in case.
Otherwise, there is a very simple and delicious way to use up leftover filling. Spread some filling on baguette slices, flatbread triangles, or crackers. Bake it for 10-15 minutes at 375°F, depending on how much filling you add to each slice.
Yes, you can wash whole mushrooms but avoid washing cut mushrooms. Mushrooms are like little sponges so when they’re cut, they will absorb a lot of liquid when exposed to it. Whole mushrooms won’t absorb liquid easily or quickly. So you can quickly rinse whole mushrooms under cold water and wipe them with a paper towel right away.
Make sure to wash mushrooms right before cooking them, not ahead of time.
