Frequently Asked Questions

Can I make this dish ahead of time?

Yes, you can prepare the dish a day in advance and store it unbaked in the refrigerator. Just cover it tightly with foil or plastic wrap. When ready to serve, bake it directly from the fridge, adding a few extra minutes to the cooking time to ensure it's heated through.

What can I use instead of canned tomatoes?

If you prefer fresh ingredients, you can substitute the canned tomatoes with about 2-3 cups of fresh tomatoes, chopped. Just be sure to add a little extra tomato juice to maintain the moisture level in the dish.

Is it possible to add other vegetables?

Absolutely! Feel free to add vegetables like bell peppers, spinach, or mushrooms to enhance the flavor and nutrition. Just be mindful of the cooking time; some vegetables may need to be sautéed longer to ensure they are tender before mixing them into the gratin.
