The backstory.
My love for Maryland-style hot crab dip started on a beach trip to Ocean City, where it seemed like every restaurant had their own version on the menu. After one bite, I was hooked on the creamy crab, melty cheese, and classic Old Bay flavor.

Now this slow cooker crab dip is one of those recipes I pull out whenever I need an appetizer I know everyone will gather around.

What you'll need.

This crockpot hot crab dip is made with simple ingredients that come together into something unforgettable.

- Garlic powder: Adds mellow garlic flavor without overpowering the crab.
- Shredded mozzarella cheese: Melts beautifully into the creamy sauce.
- Grated Parmesan cheese: Adds a salty, nutty finish that complements the seafood.
- Crab meat: Canned crab meat makes this recipe easy, but lump crab meat is always a great choice if you have it.

How to serve it.

This hot crab dip crockpot is best served warm right from the slow cooker so every scoop stays creamy and delicious.
- Sprinkle extra green onions and a light dusting of Old Bay over the top before serving.
- Serve with toasted baguette slices, buttery crackers, pita chips, or tortilla chips.
- Offer celery sticks, cucumber slices, carrots, and bell pepper strips for a lighter option.
- Spoon the dip into mini phyllo shells for an easy party appetizer.

Kori's tips.
- Drain the canned crab meat well so the dip stays thick and creamy.
- Taste before adding salt - Old Bay, Parmesan, and canned crab can already be fairly salty.
- Keep the slow cooker on warm while serving so the cheese stays smooth for the entire party.
- Adjust the lemon juice at the end if needed.
- Different brands of mayonnaise can change how much brightness the dip needs.
- No slow cooker? Bake it in a greased baking dish at 375 degrees F for 25 to 30 minutes until hot and bubbly.

The best way to reheat this crab dip is gently in the microwave in 30-second intervals, stirring between each, until hot.

TIPS: Keep the crockpot plugged in on warm, and serve it straight out of the pot. Salt to taste and adjust lemon juice to taste. The amount needed will depend on the brand of mayo you use. BAKING INSTRUCTIONS: Preheat your oven to 375°F, then transfer the prepared crab dip mixture into a greased 1½- to 2-quart baking dish. Smooth the top and sprinkle with the remaining cheese (and a little extra Old Bay if you’d like). Bake uncovered for 25 to 30 minutes, or until hot, bubbly around the edges, and lightly golden on top. Let it rest for 5 minutes before serving so it sets slightly. VARIATIONS: Swap mozzarella for pepper jack or white cheddar for a spicier twist. Add finely chopped red pepper or a splash of hot sauce for extra zip. Light mayo and cream cheese work perfectly in this recipe. Add a little dried dill, which pairs well with shellfish. SERVING SUGGESTIONS: Serve hot with toasted baguette slices, buttery crackers, or fresh veggies like celery and bell pepper strips. It also makes an amazing filling for mini phyllo cups or baked mushrooms.Nutrition
