🥫 Leftover love: how to store and reheat caramelized onions & mushrooms
Store any leftovers in an airtight container in the refrigerator for up to 3 days. This dish does not freeze well.
Marye's Tip o' the day
Wait until the onions and mushrooms are almost done to add salt and pepper. Salting too early can draw out moisture, making them steam instead of caramelize.
💭 Insider tips: things to know
- Be sure to slice your mushrooms evenly so that they cook at the same rate.
- The key to perfectly caramelized onions is to cook them low and slow. Don't rush the process!
- Resist the urge to stir the onions and mushrooms too often. Let them sit in the pan and develop those delicious caramelized bits on the bottom.
- Be sure to use butter and oil. A combination of butter and oil prevents burning and adds richness. Butter gives flavor, while oil raises the smoke point.

While fresh mushrooms will give you the best results, you can use frozen mushrooms in a pinch. Just be aware that they may release more moisture as they cook, so you may need to adjust the cooking time accordingly. I don't care for the texture of mushrooms after they've been frozen.
Sure! You can easily double or even triple this recipe to serve a crowd. Just make sure you use a large enough skillet to accommodate all of the ingredients without overcrowding.
