INGREDIENTS

  • 3 large Vidalia sweet onions sliced into half inch rings
  • 1 stick unsalted butter cut into small cubes
  • 1 cup cheddar cheese mild, shredded
  • 1 cup Gouda Cheese shredded
  • ¼ cup Mozzarella Cheese shredded (optional but recommended)
  • 1 teaspoon garlic salt
  • 1 teaspoon dried thyme
  • 1 teaspoon dried parsley
  • ½ teaspoon dried oregano
  • ½ teaspoon dried mustard
  • ¼ teaspoon cayenne pepper
  • Freshly cracked black pepper for serving

INSTRUCTIONS

  • Preheat your oven to 350 degrees F and spray a 13x9 inch baking dish with nonstick cooking spray.
  • Toss the ringed onions in a large bowl with garlic salt, dried thyme, dried parsley, dried oregano, dried mustard, and cayenne pepper.
  • Layer the seasoned onions into the baking dish, then top evenly with shredded mild cheddar, Gouda, smoked Gouda, mozzarella, and scattered butter cubes.
  • Cover the baking dish tightly with aluminum foil and bake at 350 F for 40 minutes to tenderize the onions.
  • Remove the foil and bake uncovered for an additional 30 minutes until the top cheese layer turns crusty, golden brown, and bubbly.
  • Crack some fresh black pepper one or two rinds on top and serve.

Notes

  • Shred block cheese at home for superior melting texture, as pre shredded packaged cheese contains anti caking powders.
  • Texas sweet onions or sweet yellow onions make great substitutions if Vidalia onions are out of season.
  • Rest the baked casserole for 10 minutes before serving so the bubbly cheese sets for cleaner scoops.
