Keto Crab Dip — Baked Maryland Style with Cream Cheese
/If you've never had Maryland crab dip, I need you to understand something: we take this seriously. Maryland is not a state that does seafood casually. This baked cream cheese crab dip — rich, thick, loaded with actual crab meat, seasoned aggressively with Old Bay, and finished with melted mozzarella and broiled to golden — is the recipe I make for every family gathering, every holiday, and honestly any occasion where I want people to stop talking and start eating.
It's also one of the most naturally keto-friendly appetizers that exists. Crab meat and cream cheese are both zero carb. Old Bay is zero carb. Parmesan is zero carb. The whole dip clocks in at 3g net carbs per serving, and it tastes so indulgent that no one at the party will believe you when you tell them.
Serve it hot from the oven with rainbow bell pepper strips, celery, and cucumber rounds. Or eat it cold the next day straight from the container. Both are correct.
Why you'll love this keto crab dip
3g net carbs per serving • Ready in 45 minutes • Maryland style — Old Bay is non-negotiable • Cream cheese base instead of mayo — thicker and more indulgent • Can be made ahead and refrigerated before baking • Low carb dippers included • 16g protein per serving
What Type of Crab to Use
Fresh lump crab meat — best. Found at the seafood counter, usually sold in containers of 8-16 oz. Jumbo lump or lump crab meat gives you the best flavor and texture. If you're in Maryland or the Mid-Atlantic, this is what you're using. Drain any excess liquid before using.
Canned crab from the seafood section — great value. Most grocery stores carry 6 oz cans of crab meat near the canned tuna. Quality varies by brand — look for 'lump' crab meat rather than 'claw' meat if you have the option. Drain completely before using. This is what I use most often and the dip is excellent.
Imitation crab (surimi) — avoid for this recipe. Imitation crab is made from processed fish with added starch and sugar — it's not keto-friendly and the flavor doesn't hold up in a baked dip the way real crab does.
Ingredients
1 lb crab meat — fresh lump or canned, drained
8 oz full-fat cream cheese, softened to room temperature
1/4 cup grated Parmesan cheese
2 tablespoons Old Bay Seasoning — plus more for finishing
1/2 teaspoon salt
1/2 teaspoon black pepper
1/4 cup shredded mozzarella cheese — for the top
1 scallion, thinly sliced — for garnish
Old Bay is non-negotiable | If you're not from Maryland, Old Bay might seem optional. It is not. Old Bay is the entire flavor backbone of this dip — it's a blend of celery salt, red pepper, black pepper, and paprika that's been seasoning Maryland seafood since 1939. The recipe literally does not taste like Maryland crab dip without it. It's available on Amazon at Walmart, and at most grocery stores nationwide.
Why Cream Cheese Instead of Mayonnaise
Most crab dip recipes use mayo as the base. This one uses cream cheese, and there's a good reason:
Mayo-based crab dip is thinner, slightly greasy, and doesn't hold together as well when baked. The liquid in the mayo can separate during baking, creating a slightly watery dip. Cream cheese creates a thick, rich, stable dip that holds its shape beautifully in the oven and stays creamy even after cooling.
The other advantage: cream cheese has more protein per tablespoon than mayo and zero added sugar. It's also lower in inflammatory oils — most grocery store mayo is made with soybean or canola oil.
Step-by-Step Instructions
Preheat and soften. Preheat oven to 350°F. Make sure your cream cheese is fully at room temperature — set it out at least 1 hour before starting. Cold cream cheese doesn't blend smooth.
Combine the filling. In a large bowl, combine the crab meat, softened cream cheese, grated parmesan, Old Bay, salt, and pepper. Beat with a hand mixer or stir vigorously with a wooden spoon until fully combined and the mixture is smooth without any lumps of cream cheese. This step is important — lumps of cream cheese in the finished dip are a texture issue.
Transfer to baking dish. Spread the mixture evenly in a baking dish (an 8x8 or similar size works well) using a spatula.
Bake. Bake at 350°F for 30 minutes, or until the mixture is heated through and the edges are slightly bubbling.
Add the mozzarella. Remove from the oven and immediately top with shredded mozzarella, a few extra dashes of Old Bay, and the sliced scallion.
Broil. Place under the broiler for 2-4 minutes until the mozzarella is melted and golden brown. Watch it constantly — cheese under the broiler can go from perfect to burnt in 60 seconds.
Serve. Serve immediately with bell pepper strips, celery, cucumber rounds, and any other low carb dippers. Or let cool slightly and serve warm.
Low Carb Dippers
Crackers and bread are the obvious pairing and the obvious problem for low carb eating. Here are the best substitutes:
Rainbow bell pepper strips — the sweet crunch pairs perfectly with the savory dip, and the different colors make a beautiful platter
Celery sticks — classic, holds up to a thick dip
Cucumber rounds — sliced about 1/2 inch thick; sturdy enough to scoop
Endive leaves — elegant option for parties; the boat shape is perfect for scooping
Pork rinds — unexpected but excellent; the salty crunch works with the rich dip
Simple Mills Almond Flour Crackers — for guests who want something more cracker-like
How to Make This Ahead
This is one of the best make-ahead party appetizers because it holds up well and can be fully prepared the day before:
Mix the filling. Combine all filling ingredients (everything except the mozzarella and scallion) the day before.
Transfer and refrigerate. Spread into the baking dish, cover tightly with plastic wrap, and refrigerate up to 24 hours.
Bake when ready. Take from the fridge 30 minutes before baking to take the chill off. Bake at 350°F for 30-35 minutes (slightly longer than from room temperature since it's starting cold). Add mozzarella and broil as directed.
The filling can also be served cold as a crab spread — mix, chill for 2 hours, and serve cold with dippers. It's a completely different and equally delicious application of the same recipe.
Storage
Refrigerator: store covered for up to 3 days. Reheat in a 325°F oven for 15 minutes or microwave in 60-second intervals.
Do not freeze: cream cheese-based dips don't freeze well — the texture becomes grainy and watery after thawing.
Cold leftover tip: cold crab dip is excellent as a spread on cucumber rounds or celery for a quick lunch or snack the next day.
Frequently Asked Questions
Can I use canned crab meat for this recipe?
Yes — canned crab meat from the seafood section works beautifully. Look for 'lump' or 'white' crab meat rather than 'claw' meat. Drain completely before using. The dip will taste slightly less briny and oceanic than fresh crab, but it's still excellent and significantly more affordable.
Can I make this dairy-free?
This is a challenging one to make dairy-free since cream cheese, parmesan, and mozzarella are all central to the recipe. Kite Hill almond milk cream cheese can substitute for regular cream cheese 1:1, but the texture will be softer. Dairy-free parmesan alternatives exist but don't melt the same way. For the mozzarella topping, omit it and top with extra Old Bay and scallions for a dairy-free finish.
How spicy is it?
Mildly spicy — Old Bay has a gentle heat from paprika and celery salt that's very approachable. 2 tablespoons is the classic quantity for this size dip. If you're heat-sensitive, reduce to 1 tablespoon and taste before adding more. If you want more heat, add a pinch of cayenne or extra Old Bay to the finished dip.
Can I serve this cold?
Yes — cold crab dip is its own thing, especially in summer. Make the filling, refrigerate for 2+ hours until set, and serve cold as a spread. Guests can top their dippers with as much as they want. It's a completely valid and delicious preparation — just different from the hot baked version.
Why does it say 3g net carbs if crab and cream cheese are zero carb?
The Old Bay seasoning contributes a trace amount of carbs from the spice blend. The scallion and parmesan also contribute minor amounts. The 3g net carbs comes from the totality of small contributions across all ingredients — none of which are significant individually.
