Recipe Tips

Using a silicone mat is the best way to cook vegetables properly, as the mat cooks the bottom of the vegetables thoroughly.
If you add salt and let the vegetables sit for a while, their moisture will be drawn out. Therefore, let’s roast them immediately after adding salt.
Cut the vegetables to uniform thickness and size to cook evenly.

Variations

You can cook any kind of veggie except leafy greens! Here are some ideas for variations:

Spring: Asparagus, spring onions, potatoes
Summer: Zucchini, eggplant, peppers, tomatoes
Fall: Sweet potatoes, kabocha, carrots, mushrooms
Winter: Broccoli, cauliflower, cabbage, green onion

My favorite is always onions. Roasting brings out the sweetness even if you don’t like them so much, and their tender taste will make up for it! Sweet potatoes and pumpkins are the best in the fall. It’s perfect not only as a side dish but also as a snack for children.
