Homemade crispy onions are a great way to top off any dish, and they're especially good on green bean casserole. They're easy to make with just 5 ingredients and have a super crunchy texture that everyone will love!
Preheat the oven to 450 degrees Fahrenheit (220 degrees Celsius) and line 2 large baking sheets with parchment paper.
In a large bowl, toss onions with oil, flour, panko, and salt.
Mix the onions thoroughly, then spread them evenly onto the baking sheets.
Bake in the preheated oven for 25 to 35 minutes, tossing every 10 minutes (rotating the pans in the oven as necessary) until lightly browned and crispy.
