Step 1

Empty the canned tomatoes with their juices into a large bowl and carefully crush them with your hands (you’ll have some bite-size pieces remaining). Set aside.

Step 2

Place a rack in the top third of the oven (6 to 8 inches from the broiling element) and preheat the broiler to high.

Step 3

Heat the olive oil in a large cast iron or other oven-safe skillet over medium. Add the orzo and cook, stirring occasionally, until fragrant and lightly toasted, 2 to 3 minutes. Add the garlic and sauté until fragrant, about 1 minute. Add the crushed tomatoes, oregano, red pepper flakes, and 1/2 teaspoon of salt. Stir to combine and bring to a boil. Reduce to a simmer and cook, uncovered, until the pasta is al dente, the liquid is absorbed, and a thick sauce has formed, about 10 minutes. Stir a few times while simmering to ensure the orzo doesn’t stick to the bottom of the skillet. Meanwhile, pat the shrimp dry with paper towels and season all over with salt and pepper.

Step 4

Stir the orzo once more, spread it into an even layer, and scatter the shrimp and feta over the top. Transfer the skillet to the oven and broil until the shrimp are pink and opaque and the feta is softened and lightly browned, 3 to 4 minutes. Garnish with mint before serving.
