Why You’ll Love This Cheesy Jumbo Lump Crab Au Gratin

This dish is a guaranteed showstopper with minimal effort. It makes seafood feel special without the stress. It can be prepped ahead, popped into the oven, and served up hot and melty in under 30 minutes. Perfect for holiday gatherings, cozy weekends, or impressing guests who love Southern coastal flavors.

What really makes it shine is the texture contrast: the tender crab, the creamy base, the crisp broiled top. Every layer works together to create a spoonful of sheer comfort. It’s a seafood bake that doesn’t require much but delivers so much.

What Kind of Crab Meat Should I Use?

For the best flavor and texture, go with jumbo lump crab meat. It’s pricy, but worth it when you’re making a dish that highlights seafood so beautifully. Look for refrigerated pasteurized crab meat if fresh isn’t available. Be gentle when folding it in, so those big, beautiful lumps stay intact.

If you need a more budget-friendly option, backfin or claw meat will still give you that great crab flavor. Just expect a slightly different texture. Avoid imitation crab altogether—it simply doesn’t belong in a recipe this rich and luxurious.

Ingredients for the Cheesy Jumbo Lump Crab Au Gratin

This recipe calls for just a handful of key ingredients, but each one plays a big role in building the creamy, savory base that supports the sweet crab meat.

• Jumbo lump crab meat — the star ingredient, sweet and delicate with meaty texture
• Cream cheese — brings rich creaminess and a subtle tang
• Mayonnaise — adds silky body to the sauce
• Shredded cheddar cheese — gives bold cheesy flavor and helps brown the top
• Parmesan cheese — adds salty, umami depth
• Green onions — for a light onion bite and color
• Paprika — gives mild heat and smoky depth
• Creole seasoning — adds Southern flair and a gentle kick
• Worcestershire sauce — builds background umami
• Lemon juice — brightens the richness
• Salt and pepper — to taste

How To Make the Cheesy Jumbo Lump Crab Au Gratin

Step 1: Make the Creamy Cheese Base

In a large bowl, combine the softened cream cheese, mayonnaise, shredded cheddar, parmesan, green onions, Worcestershire sauce, lemon juice, paprika, and Creole seasoning. Stir until smooth and fully incorporated.

Step 2: Gently Fold in the Crab

Carefully add the jumbo lump crab meat to the cheese mixture. Use a spatula to gently fold it in, keeping the lumps as intact as possible for that luxurious bite.

Step 3: Bake Until Bubbling

Transfer the mixture to a small cast-iron skillet or baking dish. Top with extra cheddar and a sprinkle of paprika. Bake at 375°F for about 20 minutes, or until hot and bubbly.

Step 4: Broil for Golden Perfection

For that irresistible browned top, broil the au gratin for 2–3 minutes. Watch closely to avoid burning. Serve hot with toasted baguette slices, crostini, or buttery crackers.

How to Serve and Store Cheesy Jumbo Lump Crab Au Gratin

This dish is best served piping hot, fresh out of the oven. It’s perfect as a hearty appetizer for a group of 6 or a rich main course for 2–3. Scoop it into ramekins for a more elegant presentation, or serve family-style right from the skillet.

To store leftovers, cover tightly and refrigerate for up to 3 days. Reheat gently in the oven or microwave until warmed through. Note that the texture may slightly change after chilling, but the flavors stay fantastic.
