Ingredients
Sweet Onions
2 big (sliced into 1/8 inch slices)
White Rice Flour
1/4 cup (none)
Fine Cornmeal
2 tablespoons (none)
Sea Salt
1 teaspoon (none)
Olive Oil
2 tablespoons (divided)
Instructions
1
Preheat your oven to 475°F (245°C).
2
Peel the onions and slice them in half. Then cut each half into thin 1/8-inch slices.
3
In a large bowl, toss the sliced onions with the white rice flour, cornmeal, and sea salt until they are well coated.
4
Generously grease a large baking sheet with half of the olive oil to prevent sticking. Spread the coated onions evenly across the baking sheet.
5
Drizzle the remaining olive oil over the onions to ensure they crisp up nicely.
6
Place the baking sheet on the middle rack of the preheated oven and bake for about 30 minutes, or until they are golden brown. Toss the onions every 10 minutes to promote even cooking.
7
Keep a close eye on the onions, especially in the last few minutes of baking, to prevent them from burning.
8
Once the onions are crispy and golden, remove them from the oven and allow them to cool slightly.
9
Use half of the crispy onions to mix into your green bean casserole, reserving the other half to sprinkle generously on top before serving.
