If you like to cook fish, but prefer rice as a side dish, then this option for cooking fish with rice in the oven will perfectly diversify the menu without changing your preferences.
Heat oil in a large skillet over medium-high heat. Put onion, garlic, and celery in a preheated pan. Fry for about 1 minute, add mushrooms, fry for about 3-4 minutes.
Add rice to the pan with vegetables, fry, stirring occasionally, for about 5 minutes, until the rice is light brown. Add tomatoes with juice, cayenne, and black pepper, salt to the rice.
Lightly grease the heat-resistant form with vegetable oil, put the fish fillets in the center, and put the rice mixture on the sides.
Cover the dishes with foil, put in the oven, and bake at 200 degrees for about 45-50 minutes (until the rice is cooked). Leave the baked rice for 5 minutes at room temperature before serving. Serve oven-baked fish rice with baked vegetables, sprinkle with chopped parsley and garnish with lemon wedges.
