Why You’ll Love This Recipe
I like this recipe because it’s quick to prepare and always crowd-pleasing. The creamy filling gets bubbly and golden in the oven, making every bite deliciously satisfying. I also enjoy how versatile it is—I can serve it as a main dish with a side salad or as a dip with crackers and bread.
Ingredients
(Note: All ingredient amounts are listed in the recipe card below.)
1 pound imitation crabmeat
½ large onion, finely chopped
¼ cup mayonnaise
¼ cup sour cream
4 ounces cream cheese (½ a block)
1 cup shredded Swiss cheese
2 teaspoons garlic powder
1 teaspoon dried parsley

Directions
-
I preheat the oven to 350°F.
-
In a large mixing bowl, I combine the imitation crab, onion, mayonnaise, sour cream, cream cheese, Swiss cheese, garlic powder, and parsley. I stir until everything is well mixed.
-
I transfer the mixture into a casserole dish, spreading it evenly. For extra cheesiness, I sometimes add a sprinkle of shredded cheese on top.
-
I bake the casserole for 30 minutes, or until the top is golden and bubbly.
-
I let it cool slightly before serving warm.
Servings and Timing
This recipe makes about 8 servings. It takes 10 minutes to prepare, 30 minutes to bake, and about 40 minutes total.
Variations
I sometimes add diced bell peppers or celery for extra crunch. If I want more spice, I stir in a pinch of cayenne pepper or hot sauce. For a richer flavor, I swap Swiss cheese for mozzarella, cheddar, or a blend. I also like topping it with buttery breadcrumbs for a crispy finish.
Storage/Reheating
I store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, I cover the casserole with foil and warm it in the oven at 325°F until heated through. Individual portions also reheat well in the microwave. I don’t recommend freezing because the cream cheese mixture can change texture.
