Instructions:

Caramelize the Sweet Onions:

  1. In a large skillet, heat butter and olive oil over medium heat.
  2. Add thinly sliced sweet onions and cook, stirring occasionally, until they are soft and caramelized. This may take about 20-30 minutes.

  2. Spoon half of the cheese and mayonnaise mixture over the onions, spreading it evenly.
  3. Repeat the layers with the remaining onions and cheese mixture.
  4. Top the casserole with breadcrumbs for a crunchy texture.

Bake to Perfection:

  1. Bake in the preheated oven for 25-30 minutes, or until the casserole is golden brown and bubbly.
