Cooking Tips:

- Ensure to slice the onions thinly and caramelize them slowly over low heat to develop deep, sweet flavors without burning them.

- Roast the sweet potatoes until they are tender but still hold their shape to avoid a mushy texture.

- Use a good quality blue cheese for a richer, creamier contribution to the dish.

- For added depth, consider garnishing the finished dish with extra fresh thyme or a few chopped walnuts.

- Adjust the sweetness by either adding more or less brown sugar based on your personal preference.
