2 cups Cooked Short-Grain Brown Rice
1⁄2 cup grated parmigiano-reggiano
1⁄2 tbsp. chopped fresh oregano
1⁄2 tsp. kosher salt
1⁄4 tsp. freshly ground black pepper
1 beaten egg
1⁄2 cup flour
1⁄4 cup olive oil
3 tbsp. butter, plus more for garnish
Finely chopped flat-leaf parsley leaves
1. Combine rice, parmigiano-reggiano, oregano, salt, pepper, and egg. Form rice mixture into eight 2" round cakes. Transfer cakes to a sheet tray and refrigerate for 30 minutes to allow them to firm up.
2. Put flour on a plate; dredge cakes in flour. Heat oil and 3 tbsp. of the butter in a 10" skillet over medium-high heat. Working in 2 batches, fry cakes, turning once, until golden brown, about 4 minutes per side.
3. Garnish each cake with a thin slice of softened butter and sprinkle with finely chopped flat-leaf parsley leaves.
