Rinse shrimp and pat dry. Gently separate bodies from heads. Peel all but the tail (keeping the heads and shells) and devein; set aside.Advertisement
Combine wine, broth, bay leaves, the shrimp shells and heads (if using) in a large skillet. Bring to a boil over medium-high heat. Reduce heat to maintain a simmer, cover and cook for 5 minutes. Uncover and cook at a lively simmer until reduced to about 1/2 cup liquid, 3 to 5 minutes more. Strain the stock into a bowl and discard the solids. Wipe out the pan.
Heat butter and oil in the pan over medium-low heat. Add garlic and cook, stirring, until softened but not browned, 1 to 2 minutes. Add crushed red pepper, salt and the shrimp stock. Increase heat to medium-high and cook until reduced by half, about 3 minutes.
Arrange the reserved shrimp in the pan in a single layer. Cook until pink and curled, 1 to 2 minutes per side. Add lemon juice and parsley and toss gently to combine. Transfer the shrimp to a warm platter or bowl. Serve with lemon wedges and more parsley, if desired.
Tip: Shrimp with heads can be hard to find, but they add a depth of flavor to dishes. Look for them in ethnic markets or large supermarkets. (If you can't find them, substitute uncooked shell-on shrimp.) For help choosing sustainable wild or farmed shrimp, go to seafoodwatch.org.
