Instructions
- 1
Preheat your oven to 400°F (200°C). Place crabs in the freezer for 15 minutes to make them unconscious before humanely dispatching them with a sharp knife through the cross on their shells.
Tip: This is the most humane method for preparing live crabs.
- 2
Heat olive oil in a large cast-iron skillet over medium-high heat. Add the sliced onions and cook for 15-18 minutes, stirring occasionally, until deeply golden and caramelized.
Tip: Don't rush this step—caramelization develops the sweet, complex flavors of the onions.
- 3
Push the caramelized onions to the side of the skillet and add 2 tablespoons of butter. Sauté the minced garlic for 1-2 minutes until fragrant.
Tip: Garlic burns quickly, so watch carefully and avoid browning it.
- 4
Arrange the crab halves in the skillet on top of the onions, flesh-side up. Sprinkle with salt, pepper, and place thyme sprigs over the crabs.
Tip: The onions will protect the bottom of the crab from burning.
- 5
Transfer the entire skillet to the preheated oven and roast for 15-18 minutes until the crab meat is opaque and cooked through.
Tip: Check for doneness by ensuring the meat is no longer translucent.
- 6
Remove from the oven and place the skillet on the stovetop over medium heat. Pour in the white wine and let it simmer for 2 minutes, scraping up any browned bits.
Tip: These browned bits add incredible depth to your sauce.
- 7
Remove from heat and whisk in the remaining 4 tablespoons of cold butter until the sauce is glossy and emulsified.
Tip: Add butter in small pieces and whisk constantly for a smooth, silky sauce.
- 8
Garnish with fresh chopped parsley and serve immediately with lemon wedges on the side.
Tip: The acidity of lemon brightens all the rich, sweet flavors in this dish.
