There are appetizers that quietly sit on the table—and then there are appetizers that have everyone hovering around the baking dish. Southern 4-Ingredient Baked Crab Dip belongs firmly in the second category. My husband begs me to make it whenever we have people over for fireworks, and somehow that bubbling dish of creamy crab dip is always scraped clean within minutes.
With just four simple ingredients, this easy baked crab dip delivers everything you want from a party appetizer: rich cream cheese, silky mayonnaise, tender lump crab meat, and sharp cheddar cheese baked together until hot, creamy, bubbly, and lightly golden on top. There are no complicated sauces, no long ingredient list, and no fussy preparation.
It is especially wonderful for summer cookouts, Fourth of July gatherings, holiday parties, family reunions, game-day spreads, porch suppers, and casual entertaining. Prepare it ahead, pop it into the oven when guests arrive, and serve it piping hot with crackers or toasted bread.

Ingredients
8 ounces cream cheese, softened
Cream cheese creates the rich, creamy base of the dip. Let it soften to room temperature before mixing so it blends smoothly with the mayonnaise instead of leaving little lumps throughout the mixture.
1 cup mayonnaise
Mayonnaise adds silky richness and moisture, helping create the soft, scoopable texture that makes baked crab dip so good. Use a good-quality mayonnaise for the best flavor.
8 ounces lump crab meat, drained
The lump crab meat is the star of the recipe. Its tender pieces give the dip that sweet, delicate seafood flavor while adding a pleasant texture. Drain it thoroughly and carefully check for any remaining pieces of shell.
1 cup shredded sharp cheddar cheese
Sharp cheddar provides bold cheesy flavor and a beautiful melted topping. Half goes into the creamy crab mixture, while the rest melts over the top and develops a lightly golden finish.
How to Make Southern 4-Ingredient Baked Crab Dip
1. Prepare the oven and baking dish
Preheat your oven to 350°F. Lightly grease a small glass casserole dish or baking dish to make serving and cleanup easier.
2. Make the creamy base
Place the softened cream cheese and mayonnaise in a medium mixing bowl. Stir until completely combined and smooth.
Taking a few extra moments here helps ensure your finished dip has a wonderfully creamy consistency.
3. Add the crab and cheese
Gently fold in the drained lump crab meat and half of the shredded cheddar cheese.
Stir carefully rather than aggressively mixing so you can keep some of those delicious pieces of crab intact.
4. Transfer to the baking dish
Spread the crab mixture evenly into the prepared baking dish. Sprinkle the remaining shredded cheddar cheese over the surface.
The cheese topping will melt into a bubbly, golden layer as the dip bakes.
5. Bake until hot and bubbly
Bake for approximately 25 to 30 minutes, or until the dip is heated through, bubbling around the edges, and lightly golden on top.
Keep an eye on it toward the end of baking. You want the cheese melted and golden without allowing the dip to become dry.
6. Let it rest briefly
Remove the dip from the oven and let it stand for about 5 minutes. This gives the mixture a chance to settle while remaining wonderfully warm and creamy.
Serve immediately with your favorite dippers.
Pro Tips for the Best Baked Crab Dip
Soften the cream cheese first. This is one of the easiest ways to avoid lumps and create a smooth, luxurious dip.
Drain the crab well. Excess moisture can make the finished dip watery. Give the crab a good drain before adding it to the mixture.
Pick through the crab carefully. Even good-quality lump crab can occasionally contain a small piece of shell.
Don’t overmix the crab. Folding it gently keeps recognizable pieces of crab throughout the dip instead of turning everything into a paste.
Don’t overbake. Once the dip is hot, bubbling, and lightly golden, take it out. Overbaking can make the cheese greasy and the crab less tender.
For extra flavor, use extra-sharp cheddar. The stronger cheese works beautifully with the mild sweetness of the crab.
For a spicy version, add a few dashes of hot sauce or a small amount of finely diced pickled jalapeño. Keep the additions modest so they complement rather than overpower the crab.
Make-Ahead Instructions
This easy crab dip is especially convenient when you’re entertaining.
Prepare the mixture according to the recipe, spread it into the baking dish, cover, and refrigerate for several hours before your gathering. When you’re ready to serve, place it in the oven and allow a few additional minutes of baking time because the dip will be starting cold.
This makes it an excellent appetizer for parties and holiday gatherings, when you want to spend less time in the kitchen once your guests arrive.
What to Serve With Crab Dip
Serve this hot baked crab dip with sturdy dippers that can handle its creamy texture.

It is particularly inviting when placed in the center of a casual appetizer table while everyone gathers around waiting for the fireworks.
Why This Recipe Is Always a Party Favorite
The magic of this 4-ingredient crab dip is how much flavor comes from such a short ingredient list. The cream cheese gives it richness, mayonnaise keeps it silky, lump crab brings delicate seafood flavor, and sharp cheddar provides the savory, bubbly finish.
