Start to finish: 50 minutes
Hands on time: 40 minutes
¼ cup extra-virgin olive oil, divided
12 ounces peeled, and deveined jumbo shrimp
1 cup finely chopped onion
1 tablespoon minced garlic
1 cup halved cherry tomatoes
2 teaspoons red pepper flakes
10 ounces baby spinach, torn kale, or torn mustard greens
Freshly ground black pepper
½ cup dry white wine
2 cups cooked farro
1 tablespoon chopped fresh oregano
4 ounces feta cheese, crumbled
1 cup chicken broth
Preheat the oven to 400 F.
Heat 1 ½ tablespoons of the oil in a large skillet with a heatproof handle over high heat. Add the shrimp and cook, undisturbed, until the shrimp turns golden 1 minute. Turn them over and cook them until they are barely golden, about 1 minute more (they should not be cooked through). Transfer the shrimp with tongs to a colander set over a bowl.
Add another tablespoon of the oil to the skillet, reduce the heat to medium low and add the onion along with a hefty pinch of salt. Cook the onion, stirring occasionally, until it is golden, about 10 minutes. Add the garlic, the tomatoes and the red pepper flakes and cook, stirring for 1 minute. Transfer the mixture to the colander with the shrimp.
Increase the heat to high, add the remaining 1 ½ tablespoons oil and half the greens and cook, stirring until they start to wilt. Add the remaining greens, and continue cooking until all the greens are wilted. Add salt and pepper to taste and transfer the greens to the colander that the shrimp are in and shake it to get as much cooking liquid from the colander into the bowl as possible.
Add the wine and the reserved cooking liquid from the colander to the skillet and boil until the mixture is reduced to a few tablespoons. And the farro, the oregano, half the feta and the stock to the skillet and bring the stock to a boil. Stir in all the ingredients in the colander and push the shrimp down slightly into the farro. Top the shrimp with the remaining crumbled feta and transfer the pan to the oven. Bake for 10 minutes or until the cheese is melted. Serve right away.
