Step 1

Preheat oven to 400F.

Step 2

Heat oil in a large 12-inch cast-iron skillet or oven-safe skillet over medium-high heat until the hot oil sizzles, about 2 minutes. Add mushrooms, onion, and garlic and sauté until tender and fragrant, about 3-4 minutes.

Step 3

Pour in diced tomatoes and chicken broth. Turn the heat down to medium and stir well to mix. Bring the mixture to a simmer, about 3-4 minutes.

Step 4

Stir in orzo and season with Italian seasoning, salt and pepper. Arrange shrimp evenly over orzo and sprinkle feta cheese on top.

Step 5

Bake for 15-20 minutes until the shrimp turn opaque. Orzo should double in size when it is cooked. Let rest for 5 minutes before serving. Drizzle with lemon juice, fresh basil, and additional feta, if desired, and serve.
