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.

Beergarita
My go to drink for summer gatherings is this refreshing Beergarita, and let me tell you, it's a total crowd pleaser. The combination of tequila, triple sec, fresh lime juice, and a cold Corona creates something that tastes way more complicated than it actually is. Lime juice is packed with vitamin C, which is great for your immune system, and the whole thing takes just five minutes to throw together. Best part? It's incredibly budget friendly since you're probably already stocking most of these ingredients anyway.
