Now these stuffed mushrooms do take some time and effort.

But you’ll find they’re totally worth it. That’s because these mushroom appetizers will disappear in a heartbeat at your holiday party.

So, double the mushroom recipe. This way you can keep one batch of appetizers in the oven warm on a platter waiting to go!

Making world’s best stuffed mushrooms on a budget

Concerned that making a crab appetizer will affect your party budget?

Here’s a tip – use imitation crab! Make sure the brand you use is certified gluten free.

What I love about using imitation crab for mushroom appetizers and other recipes is that it’s fully cooked, sweeter and less fishy than real crab, and doesn’t fall apart in your cooking.

If you find imitation crab on sale, stock up and keep the extra in the freezer.

I use imitation crab in Crab Pasta with Pesto, Mushrooms & Tomatoes, a family favorite.

Tips to make these amazing gluten free crab stuffed mushroom appetizers

Concerned about timing? Then start making stuffed mushrooms the day before the party!

Prepare the mushrooms (the peeling of the outer skin) and vegetable/crab stuffing the day before the party.

Then cook the mushrooms and prepare the final stuffing and baking just before the party begins so your mushroom appetizers arrive freshly baked from the oven.

If your party is more on the casual side, have your guests help prepare the final bake by spooning the stuffing into the mushroom caps.

I’m sure you have a few friends who think they’re Julia Child or Martha Stewart and would love to help bake up some gluten free crab stuffed mushrooms!

Or the kids can help make the mushroom appetizers. Don’t forget to bring out your extra holiday aprons, for a festive touch!

Make gluten free stuffed mushroom appetizers

Besides making sure the imitation crab is gluten free, you must do the following to make sure this is a gluten free recipe:

Use a gluten free bullion powder: I recommend Massel Vegetable Flavor Bouillon Stock Powder (Gluten-Free).

You can purchase it online if you can’t find it at your grocery store or health food store.

I love Massel Bouillon for making stock when you need just a bit for a recipe, you don’t have time to defrost frozen stock, or you forgot to pick up a few cans of stock at the store.

Put a few tablespoons of  gluten free Massel Bouillon powder in the cooking water when you’re making rice or quinoa or use it to jazz up vegetable sauté.

Gluten free panko or GF bread crumbs: You can find gluten free panko style bread crumbs at health food stores, natural grocery stores, and online.

If you can’t find gluten free panko, you can try gluten free bread crumbs.

Make your own from gluten free toast ground up in a blender. Or use gluten free cereal or rice crackers placed in a zip lock baggie and crushed with a rolling pin!

Baking: Bake the gluten free crab stuffed mushroom appetizers on silicone baking mats makes for easy cleanup!

Go dairy free and vegan: To make this easy stuffed mushroom appetizer dairy free, use a vegan buttery spread and a vegan substitute for Parmesan cheese.
