How to Make Imitation Crab Casserole

Step 1: Preheat the Oven

Preheat your oven to 325ºF so it’s ready to go once the mixture is prepared.

Step 2: Mix the Base

In a large mixing bowl, combine the imitation crab, half the mozzarella and Colby Jack cheese, diced celery, white parts of green onions, sour cream, softened cream cheese, mayonnaise, Worcestershire sauce, lemon juice, and garlic salt.

Stir everything together until it’s smooth and evenly mixed.

Step 3: Assemble the Casserole

Spoon the mixture into a greased 8×8 or round baking dish.

Sprinkle the remaining mozzarella and Colby Jack cheese evenly over the top.

Step 4: Bake Until Bubbly

Bake for about 20 minutes, or until the cheese is golden brown and the casserole is hot and bubbly.

Step 5: Garnish and Serve

Remove from the oven and sprinkle with the green ends of the sliced green onions.

Serve warm with crackers, crusty bread, or even spooned over baked potatoes.

What to Serve It With

Crispy baguette slices or garlic bread for scooping.

Tortilla chips or pita chips as a warm dip.

Serve with a side salad for a balanced meal.

Great alongside roasted vegetables or baked potatoes.

Variations / Substitutions

Use real lump crab meat for a fancier twist.

Swap sour cream with plain Greek yogurt for a tangier, lighter option.

Add chopped red bell pepper or jalapeño for extra color and kick.

Sprinkle breadcrumbs on top for a golden crust.

Storage & Leftovers

Let the casserole cool completely before storing.

Store leftovers in an airtight container in the fridge for up to 3 days.

Reheat in the oven or microwave until hot and bubbly again.

You can also prep and refrigerate the mixture ahead of time, then bake when ready.
