A cheesy dip for the onion lover in all of us. I serve it with crackers but you can also use breadsticks. Be careful about over-baking as the cheese will harden and be difficult to dip crackers in.

Recipe Ingredients

  • 1 tablespoon butter, or as needed
  • 1 ¼ cups chopped sweet onion (such as Vidalia®)
  • ⅓ cup mayonnaise
  • 2 cups shredded Swiss cheese

Cooking Directions

  1. 1 Preheat oven to 350 degrees F (175 degrees C).
  2. 2 Melt butter in a skillet over medium heat. Cook and stir sweet onion in hot butter until browned, 5 to 7 minutes; transfer to a bowl. Add mayonnaise to the onion and stir; pour into a 9x13-inch baking dish. Sprinkle Swiss cheese over the mixture.
  3. 3 Bake in preheated oven until the top is bubbling and lightly golden, about 35 minutes.

  1. Really good. Even the kids likes it. The edges got extra brown and every one was fighting over the "crispy edges".
  2. Made this for Christmas day buffet. I LOVED it! The family turned up their nose when I told them what it was but they kept coming back for more.
  3. Delicious. Just delicious.
  4. The browned onions added a lot of flavor to this. Don't use too much butter or you will end up with a greasy dip.
  5. This is an outstanding dip by instead of using just mayonnaise I used Hellman's mayonnaise with Olive oil it was just awesome. Crazmom in Indiana
