Equipment:

  • Slow cooker I recommend using a 4-5 quart slow cooker for these mushrooms. I have used a 2.5 quart for a half batch which also works well.
  • Baking dish If you prefer to bake these stuffed crab mushrooms you will need a 13 by 9 inch baking dish.
  • Measuring cups Measuring cups are good to have on hand for measuring out the ingredients like the cheeses and sour cream needed for the crab filling.
  • Measuring spoons Measuring spoons are good to have for getting an accurate measurement of the Cajun and Old bay seasoning needed for these crab stuffed mushrooms.

Try serving these mushrooms with Homemade Barbequed Meatballs or White Chicken Skillet Lasagna. These crab stuffed mushrooms are a great side option for the holidays and pair very well with a seafood cheeseball too.

Do I need to pre-cook the mushrooms before stuffing them with the crab and cheese filling?

No, you do not need to pre-cook the mushrooms because they cook/bake very nicely while stuffed. I find that baking them or slow cooking them with the cream cheese/crab filling helps the flavors to blend together nicely.

Can I adjust the seasonings in the crab filling?

Sure! The seasonings in this recipe can be adjusted to taste. Feel free to add more or less seasoning to your preference!

What can I use if I am not a fan of imitation crab meat?

If you are not a fan of imitation crab you can always substitute the crab with finely chopped imitation lobster or even pre-cooked mini shrimp.

Ingredients needed for these crab stuffed mushrooms: mushrooms, cajun seasoning, imitation crab meat, parmesan cheese, sour cream, cream cheese and shredded mozzarella cheese.

Crockpot method: I did half of a batch of these crab stuffed mushrooms in my 2.5 quart crockpot and they were done in around 4 hours. Cooking times may vary depending on crockpot size and strength. Cook until the mushrooms are softened to preference and the filling is hot.

Combine the filling and then wash the mushrooms and remove the stems. Fill the mushrooms with the filling and then place into a baking dish or crockpot.

Slow cook or bake until the mushrooms are soft and the filling is hot.

My preference for the stuffed mushrooms is to bake them in order to get that nicely browned topping. However, cooking them in the crock pot does not change the flavor and is a great option if you need to prep them ahead of time or need extra space in your oven!
