Baked rice casserole with meat, peas, and cheese is a comforting southern Italian classic. This high protein mediterranean family dish is freezer-friendly and perfect for feeding a crowd.
Preheat the oven to 375°F. Grease a large casserole dish with 1 tbsp olive oil.
Boil Arborio rice in salted water until just al dente, about 10 minutes, then drain thoroughly.
In a skillet over medium heat, sauté ground beef in 1 tbsp olive oil with kosher salt, black pepper, and nutmeg for 8–10 minutes until browned and moisture evaporates.
Combine cooked rice, sautéed beef, peas, mozzarella cheese, Parmesan cheese, and eggs in a large mixing bowl. Mix gently to distribute ingredients evenly.
Spread the mixture into the prepared casserole dish. Top with extra cheese if desired. Bake uncovered at 375°F for 35–40 minutes, until golden and bubbling. Rest for 10 minutes before serving.
