Step 1

Preheat the oven to 350˚F. Spray a small baking dish or 6-inch cast iron pan with non-stick cooking spray. Line a sheet pan with foil for easy cleanup. Set aside.

Step 2

Combine the onion, mayonnaise, cheese and 2 teaspoons of the fresh herbs (if using) in a medium size bowl. Stir well to combine.

Step 3

Transfer the onion mixture to the prepared pan and set the pan on the foil-lined sheet pan.

Step 4

Bake for 30-40 minutes until bubbly and lightly golden. (Don't bake too long as the mayo can separate.)

Step 5

Garnish with the remaining teaspoon of fresh herbs (if using). Serve hot and enjoy!
