1 tbsp olive oil — for sautéing onion and beef.
1 small onion, diced — adds sweetness and depth.
2 cloves garlic, minced — aromatic flavour boost.
1 cup white rice, uncooked — helps bulk the dish and soak up the sauce.
2 cups beef broth — liquid to cook the rice and flavour the whole bake.
1 can (10.5 oz) cream of mushroom soup — creamy binder and umami richness.
1 can (10.5 oz) cream of celery soup — adds mellow creamy texture and celery note.
½ cup milk — lightens the sauce and helps everything bind.

Instructions

Preheat the Oven: Set your oven to 350 °F (175 °C).
Cook the Beef Mixture: In a large skillet, heat olive oil over medium heat. Add the diced onion and cook until soft, about 3 minutes. Stir in the garlic and ground beef, cooking until the meat is browned. Drain any excess fat.
Prepare the Casserole Base: Add the uncooked rice to the skillet with the beef mixture. Stir to combine. Pour in the beef broth, cream of mushroom soup, cream of celery soup, milk, Worcestershire sauce, oregano, black pepper, and salt. Mix well.
Assemble and Bake: Transfer the mixture to a greased 9×13-inch baking dish (grease well so it doesn’t stick). Cover with foil and bake for 40 minutes.
Add Cheese and Finish Baking: Remove foil, stir in frozen peas and mushrooms (if using), and sprinkle the cheddar and mozzarella cheese over the top. Bake uncovered for an additional 10 minutes, or until cheese is melted and bubbly.
Garnish and Serve: Remove from the oven, let sit for 5 minutes (resting helps it set), then sprinkle with fresh parsley before serving.

Notes

If you use a smaller baking dish the layer will be thicker and may require longer baking time.
Let the dish rest after baking to firm up a bit and make clean slices.
You can add extra vegetables (bell pepper, zucchini) or change up the cheese for more flavour.
If the rice seems under-done at the 40-minute mark, add a splash more broth, cover again for a few minutes.
