    Chef's pro tip

    Drain the cauliflower florets properly before layering them in the baking dish. By doing this, your dish will retain a perfect texture. Also, take your time cooking the onions; stir them frequently at medium heat. This process might take a bit longer, but it's essential for achieving that perfect sweet, golden flavor.
