Preheat your oven to 180°C (350°F) so it’s fully hot and ready by the time your casserole goes in. While the oven is heating, lightly grease your baking dish using a small amount of butter or oil, making sure to coat the bottom and sides evenly. This prevents sticking and helps you serve clean, beautiful portions later.

Wash all your vegetables thoroughly under running water, then pat them dry with a clean towel. Chop everything into evenly sized, bite-sized pieces—this is important because uniform pieces cook at the same rate, giving you a perfectly balanced texture in every bite without some pieces being overcooked while others stay firm.

Place a large skillet on medium heat and add the butter. Let it melt gently without browning, then add the minced garlic. Stir it continuously for about 20–30 seconds until it becomes fragrant. Be careful not to burn it, as garlic can turn bitter quickly if overheated.

Add your chopped vegetables into the skillet and spread them out evenly. Let them sauté for about 5–7 minutes, stirring occasionally. You’re aiming for slightly softened vegetables with a bit of bite left—they should not be fully cooked at this stage, as they will continue cooking in the oven.

In a separate mixing bowl, add the heavy cream, softened cream cheese, half of your shredded cheese, and all the seasonings. Mix everything together thoroughly until you get a smooth, creamy consistency with no lumps. If needed, use a whisk or spoon to break down the cream cheese completely.

Carefully add the sautéed vegetables into the creamy mixture while they are still warm. Gently fold everything together using a spatula or spoon, making sure every piece of vegetable is evenly coated in the sauce without mashing or breaking them.

Transfer the entire mixture into your prepared baking dish. Spread it out evenly using the back of a spoon or spatula, making sure it reaches all corners of the dish for even baking.

Sprinkle the remaining shredded cheese evenly over the top. Try to cover the entire surface so you get that beautiful golden, cheesy crust in every portion once it bakes.

Place the dish in the preheated oven and bake for 25–30 minutes. You’ll know it’s ready when the top turns golden brown, the edges are slightly bubbling, and the center is heated through. For an extra golden top, you can broil it for the last 2–3 minutes, but keep a close eye to avoid burning.

Remove the casserole from the oven and let it rest for 5–10 minutes before serving. This step is important because it allows the sauce to thicken slightly and helps the casserole set, making it easier to slice and serve while also enhancing the overall flavor and texture.
