Oysters & Mushroom Dip

This hot dip has Louisiana roux-building in its bones. Flour and oil cooked slowly in a heavy skillet until the color of pale peanut butter, then built up layer by layer with the holy trinity-adjacent combo of shallots, celery, and garlic. Meaty chopped mushrooms go in next with shucked oysters and their precious liquor, which is what gives the dip its briny, oceanic backbone.

The oyster liquor is not optional here. That pale, salty liquid that comes out of the oysters when you shuck them carries the entire sea-taste of the dish. Catching every drop (over a bowl, with a fine-mesh strainer if needed) matters. A slow simmer of 15 to 20 minutes tenderizes the mushrooms while the roux thickens the sauce around the oysters, leaving them just cooked through and silky rather than rubbery.

Pro Tips

• Patience with the roux. Stir constantly over medium heat and do not walk away; burnt roux means starting over.
• Do not overcook the oysters. Once the edges just start to curl, the dip is ready.
• Use fresh oysters and their liquor from the shell if you can. Pre-shucked pints from the seafood counter also work, just use all the juice.
• Serve in a warmed chafing dish or mini slow cooker to keep it hot for a party.

Variations

• Add a splash of Tabasco or a pinch of cayenne for a Cajun-style heat.
• Swap half the mushrooms for diced red bell pepper for color and sweetness.
• Stir in a quarter cup of heavy cream at the end for a richer, more luxurious dip.
