  • 8 medium onions
  • 3/4 cup grated cheese
  • 1 1/2 cups white sauce

Instructions

Tips & Substitutions

For added flavor, consider sautéing the onions in a bit of olive oil before baking. You can substitute the white sauce with a creamy ranch dressing for a different twist. If you prefer a sharper taste, try using aged cheddar or a mix of cheeses. Ensure the cheese is well grated to blend easily into the sauce.
