Making world’s best crab stuffed mushrooms on a budget

Concerned that making a crab stuffed mushroom recipe will affect your party budget? Here’s a tip – use imitation crab! Make sure the brand you used (I suggest Trans-Ocean Crab Classic) 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.

Concerned about timing? Then start making Crab 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 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!

If you’re looking for a gluten free vegetable bullion powder, I recommend Massel Gluten-Free, Vegetable Flavored All Purpose Bouillon & Seasoning Granules. 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 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 style bread crumbs can be found 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 crab stuffed mushroom appetizers recipes on silicone baking mats makes for easy cleanup! Since I have odd sized baking sheets, I took my Wilton Easy Flex Silicone Baking Mats and cut them to size. Since they’re inexpensive, I didn’t feel bad about “wrecking” them.

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

    I would love to try the BBQ Crab Cakes with corn Salsa. My hubby loves Crab cakes and this sounds like a great taste twist.
