This is a great, quick way to serve beautiful, fresh, head-on shrimp. Got someone coming over in 20 minutes? This is your go-to.
Technique tip: Don't be afraid of the heads — they really make this dish. You don't have to serve them with the heads on, but when you're cooking them, gently crush the heads with the back of a spoon. This squeezes out a lot of extra flavor that amps up the dish.
Swap option: You can use mild white fish instead of shrimp.
In a small nonstick pan, toast the fennel seed and black pepper over medium-low heat until aromatic, about 3 minutes. Allow to cool and then grind in a spice grinder. In a bowl, combine the ground fennel and black pepper with the Aleppo pepper and salt. Lay the shrimp on a baking sheet and generously season both sides with the pepper mixture.2.
Heat the oil in a large heavy skillet or Dutch oven over medium-high heat. Add the shrimp and sear for 1½ minutes. Flip the shrimp, add the garlic and oregano, and cook for 10 seconds. Deglaze the pan with the white wine, being sure to stir with a spoon to the bottom of the pan.3.
Add the stock and tomatoes and cook until they are heated through. Crush the shrimp heads with the back of a spoon to release the juices. Remove from the heat and fold in the butter and lemon juice, quickly but gently. Serve over rice.
