Before starting, pick through the crab gently for any shell pieces. Remove and discard them. Preheat the oven to 350F.
Combine the ingredients for the dip gently in a large bowl until evenly combined, being careful to not break up any of the large pieces of crab if possible.
Transfer the dip into a medium baking dish (about 8 inches diameter).
Bake the crab dip for 20-30 minutes until browned on top and bubbly throughout. Rest for 5-10 minutes, then serve with your favorite dippers. Garnish with extra scallions if you'd like. YUM.
Notes
Crab Meat: Don't worry about buying the most expensive crab meat you can, anything that is on sale will be perfect in this dip. Jumbo, lump, and claw meat all work perfectly in this dip.Cajun Seasoning: Tony Chachere's is my favorite!Make-Ahead: Make the entire dip in advance up to the last baking step and keep it in the fridge, covered, for up to 3 days. Bake it uncovered per the instructions, and enjoy!This dip is gluten free as written, check your labels just in case.Serving: This dip is delicious served with crackers, endive leaves, red pepper pieces, or fresh bread for dipping and scooping.
