9x13-inch Baking Dish

Ingredients

Main

12 oz lump crab meat drained, shells removed
8 oz cream cheese softened
1/3 cup sour cream
1/3 cup mayonnaise
1 cup shredded mozzarella cheese divided
1 green onion finely sliced (plus extra for garnish)
2 garlic cloves minced
1 tsp Worcestershire sauce sugar-free
1/2 tsp soy sauce or coconut aminos
1/4 tsp black pepper

Instructions

Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish with butter or a non-stick spray to prevent sticking and ensure smooth serving.
In a large mixing bowl, combine the softened cream cheese, sour cream, and mayonnaise. Mix thoroughly using a spatula or hand mixer until smooth and creamy, with no lumps remaining. This forms the base of the casserole and should be fully blended.
Add the minced garlic, sliced green onion, Worcestershire sauce, soy sauce or coconut aminos, and black pepper. Stir well to evenly distribute the seasonings and aromatics throughout the mixture. Taste and adjust seasonings if desired.
Gently fold in the lump crab meat, being careful not to break it apart too much—keeping some larger pieces creates a more luxurious texture. Add half of the shredded mozzarella and fold again until the mixture is evenly combined.
Transfer the mixture into the prepared baking dish. Use a spatula to spread it out into an even layer, smoothing the top for uniform baking.
Sprinkle the remaining mozzarella cheese evenly over the surface of the casserole. This creates a beautifully melted, golden top as it bakes.
Bake for 25–30 minutes, or until the edges are bubbly and the top is melted and lightly golden. If a deeper golden crust is desired, broil the casserole for 1–2 minutes at the end—watching closely to prevent burning.
Remove from the oven and allow the casserole to cool for 5 minutes. Finish by sprinkling additional sliced green onions on top for a fresh, bright bite before serving.

Notes

For extra flavor, add a splash of hot sauce or a squeeze of lemon before baking. This casserole pairs wonderfully with a simple side salad or sautéed low-carb vegetables.
