In a large skillet, heat the EVOO, four turns of the pan, over medium-high. When the EVOO begins to shimmer, add the onion and garlic. Cook, stirring, until the vegetables soften, 4-5 minutes.
Add the shrimp and lemon zest; season with salt and pepper. Toss until the shrimp is pink and opaque in the center, 2-3 minutes. Add the vodka; toss for 1 minute. Add the creme fraiche and stir until the sauce is smooth. Off the heat, stir in the parsley and basil. Divide the shrimp among shallow bowls and drizzle with a few drops of the lemon juice. Serve with the crusty bread.
