Crab cakes were always one of my favorite treats when dining out! Loaded with crab meat and fried to perfection, these meaty medallions were an indulgence that I wrote off after becoming low carb. Luckily, they are so easy to replicate and make keto friendly!
What I love most about this recipe is that each stuffed mushroom is nearly an entire meal. Portion control, especially with a crab cake, can be tough. The mushroom cap is the perfect way to feel “full” while holding all the glorious crab cake stuffing. As they bake, the flavors and juices seep into the mushroom, marinating in that classic flavor of old bay and garlic.
To keep these caps keto friendly, we skip the traditional panko bread crumbs and use Parmesan and almond meal as a light filler and a crispy, cheesy, topping! You might notice that the fat content isn’t as high as it could be, with the addition of only some butter, which was purposefully done to allow room for any mayonnaise dipping you might want to include!
