Variations

10 FAQs

  1. Can I use yellow onions instead of sweet onions?

    While best fresh, you can prepare the onions and store them in the fridge. Reheat them in the oven before serving.

    These onions make a great side for steak, grilled meats, burgers, or sandwiches.

    While you can freeze them, the texture might change when reheated. It’s better to store them in the fridge for short-term use.
