Sautéed Zucchini and Onions FAQs
Let the sautéed zucchini and onion cool entirely before storing. Transfer to an airtight container and refrigerate for up to 3 days. To reheat, warm in a skillet over medium heat with a drizzle of olive oil or reheat on a baking sheet in the oven at 350°F until warmed through.
For this recipe, I used the regular dark green variety you can find in any store in the U.S. If you happen to see them, buy the Italian variety. They are sometimes called “Mexican zucchini.”
No, the skin is tender, adds color, and helps the slices hold their shape.
Serving Suggestions
I love serving this sautéed zucchini and onion as an easy Italian side dish alongside Juicy Oven Roasted Chicken, Baked Italian Sausage, or a cozy Dutch Oven Pot Roast. It’s also delicious layered over Italian Bread for a rustic appetizer. If you have leftovers, use them to make this Italian Frittata!
