This low carb 4-ingredient crab meat bake is the kind of dish that makes a weekend feel special without turning your kitchen upside down. My dad used to make something like this on certain spring weekends when the weather was just starting to warm up, and it always felt like we were splurging on a fancy restaurant order. It’s rich, creamy, and savory, with sweet crab tucked under a bubbling golden blanket of cheese. With only four ingredients and one baking dish, it’s a practical little luxury you can pull together even on a busy day.
Serve these crab meat bakes hot from the oven with a simple green salad dressed in lemon and olive oil, or a side of steamed asparagus or green beans to keep things light and low carb. They’re lovely alongside roasted broccoli or cauliflower, too, since the veggies soak up some of that creamy sauce on the plate. If your family isn’t watching carbs, you can add a basket of crusty bread or buttered toast points for dipping into the rich, cheesy crab. A squeeze of fresh lemon and a sprinkle of chopped parsley on top right before serving also adds a nice, bright finish.
Low Carb Crab Meat BakesServings: 4
Ingredients
1 pound lump crab meat, picked over for shells
1 cup full-fat mayonnaise
1 tablespoon Old Bay or other seafood seasoning
1 1/2 cups shredded white cheese (such as mozzarella or Monterey Jack), divided
Directions
Preheat your oven to 375°F (190°C). Lightly grease a medium ceramic baking dish or four small individual baking dishes so the crab mixture doesn’t stick.
In a medium mixing bowl, combine the mayonnaise and Old Bay seasoning. Stir until the seasoning is evenly blended into the mayo, making a smooth, pale orange sauce.
Fold in 1 cup of the shredded white cheese, mixing gently so the cheese is coated but not clumped. This cheesy mayo mixture will become the rich, creamy base that holds the crab together.
Add the lump crab meat to the bowl. Using a spatula or your hands, gently fold the crab into the mixture, being careful not to break up the lumps too much. You want a thick, spoonable seafood mixture with plenty of visible crab pieces.
Spoon the crab mixture into the prepared ceramic baking dish (or divide evenly among individual dishes), smoothing the top so it’s level. Sprinkle the remaining 1/2 cup shredded cheese evenly over the surface, covering the crab mixture from edge to edge.
Place the dish on the middle rack of the preheated oven and bake for 18–22 minutes, or until the edges are bubbling and the top is melted and starting to turn a light golden brown. If you like a deeper crust, you can switch the oven to broil for 1–2 extra minutes, watching closely so the cheese doesn’t burn.
Remove the crab bakes from the oven and let them rest for about 5 minutes. The interior will be very hot and creamy, and this short rest helps everything set just enough while still staying luxuriously soft. Serve warm, scooping straight from the dish, and enjoy that rich, bubbling, restaurant-style feel right at your own table.
Variations & Tips
For kids or picky eaters who are sensitive to seasoning, cut the Old Bay down to 1–2 teaspoons and let adults add extra at the table. If someone in your family doesn’t love crab, you can swap in cooked, chopped shrimp or a mix of crab and shrimp while keeping the rest of the recipe the same. For a slightly lighter version, you can use half mayonnaise and half plain Greek yogurt, though it will be a bit tangier and not quite as rich. If you like a little kick, stir a pinch of cayenne or a few dashes of hot sauce into the mayo before mixing. To stretch the dish for a crowd, spoon smaller portions into a muffin tin lined with silicone or well-greased cups, top with cheese, and bake until bubbly for mini crab bakes. A sprinkle of fresh herbs like parsley or chives after baking adds color without adding ingredients to the base recipe. If you need to make this ahead, assemble the crab mixture and cheese topping, cover, and refrigerate for up to a day, then bake just before serving, adding a few extra minutes to the bake time if it goes into the oven cold.
