Ingredients

• 2 cups frozen stir fry vegetables (bell peppers, snow peas, carrots, broccoli, baby corn)
• 1 cup cooked rice (white, brown, or jasmine)
• 1 cup cooked chicken or tofu (optional for protein)
• 1 cup shredded cheese (cheddar, mozzarella, or vegan alternative)
• 1 can (10.5 oz) cream of mushroom or cream of celery soup (or homemade vegan bechamel sauce)
• ½ cup sour cream or plain yogurt (for creaminess)
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 2 tbsp olive oil
• Salt and pepper, to taste
• 1 tsp dried thyme or Italian seasoning
• ½ cup bread crumbs (optional, for topping)

Equipment

• Oven-safe casserole dish (8×8 inches or similar)
• Large mixing bowl
• Skillet or frying pan
• Wooden spoon or spatula
• Measuring cups and spoons
• Knife and cutting board
• Aluminum foil (optional)

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease the casserole dish with olive oil or cooking spray.
2. Sauté the aromatics: Heat 2 tablespoons of olive oil in a skillet over medium heat. Add the finely chopped onion and cook until translucent, about 3-4 minutes. Add the minced garlic and cook for another 30 seconds until fragrant.
3. Add the frozen stir fry vegetables to the skillet. Sauté for 5-7 minutes until they are thawed and slightly tender but still crisp. Season with salt, pepper, and dried thyme or Italian seasoning.
4. Combine the casserole base: In a large mixing bowl, combine the cooked rice, sautéed vegetables and aromatics, cooked chicken or tofu (if using), cream of mushroom soup, and sour cream. Mix until everything is evenly coated and creamy.
5. Transfer the mixture into the prepared casserole dish and spread it out evenly.
6. Top with shredded cheese and sprinkle bread crumbs on top for a golden crust (optional but highly recommended).
7. Bake uncovered for 25-30 minutes, or until the cheese is bubbly and golden brown.
8. Remove from oven and let the casserole cool for 5 minutes before serving. This allows it to set and makes serving easier.

Tips & Variations
