Preheat the Oven: Preheat your oven to 375°F (190°C). This ensures that your casserole will bake evenly and become golden and bubbly.

Prepare the Vegetables: Chop the broccoli into bite-sized pieces. This helps them cook evenly and makes them easier to eat.

Chop the onion and bell peppers into small, even pieces to ensure consistent cooking and flavor distribution.

Sauté the Vegetables: Heat a generous amount of olive oil in a large skillet over medium heat.

Add the chopped onion and cook until it becomes translucent and slightly golden, about 5-7 minutes.

Add the chopped bell peppers and cook for another 5 minutes until they start to soften.

Stir in the chopped broccoli and cook for an additional 5 minutes, until the broccoli is tender but still crisp.

Combine Ingredients: In a large mixing bowl, combine the sautéed vegetables with the vegetable broth and milk. Stir well to combine.

Season with salt to taste. If you like, you can add other seasonings such as black pepper, garlic powder, or herbs like thyme or oregano for extra flavor.

Add Rice: Stir in 1 cup of uncooked rice (not listed in the original ingredients but typically used in this kind of casserole) into the mixture. This allows the rice to absorb the flavors and cook as the casserole bakes.

Transfer to Baking Dish: Pour the mixture into a greased baking dish. Spread it out evenly with a spatula to ensure even cooking.

Bake the Casserole: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the casserole is bubbly and the rice is tender.

For a crispy top, you can broil the casserole for an additional 2-3 minutes, but watch closely to avoid burning.

Cool and Serve: Allow the casserole to cool slightly before serving. This makes it easier to cut and helps the flavors meld together.

Garnish with fresh herbs like parsley or chives if desired.
