This sweet Vidalia onion dip is an absolutely fabulous crowd pleasing appetizer

I’m telling you right off the bat, run to the store and pick up your ingredients (there’s a list below) and a baguette, then run back and read the post. Hurry. It’s too good to miss. I swear I won’t sink that slice of grilled bread into the creamy cheesy, oniony dip until you get back, but get a move on, I’m only human…

We’re a serious dip-for-dinner kind of family so you can take if from me, this is a winner. It’s challenging my all time favorite, spinach artichoke. This one is even easier to make, and it’s bursting with fresh onion flavor without any questionable ingredients (I’m looking at you, dry onion soup mix.)  Not sure if it’s the sweet onion, the mix of cheeses, or a combination, but it just works.

What you’ll need for the best baked onion dip

  • a sweet onion like Vidalia or other variety. It will be with the other onions in your produce aisle
  • sour cream
  • mayonnaise
  • an aged Italian cheese like Grana Padano, or Parmesan, Romano, Asiago etc.
  • mozzarella 
  • white cheddar cheese
  • salt and fresh cracked black pepper
  • hot sauce
  • Worcestershire sauce

Some like to caramelize their onions for a dip like this, but I prefer to keep them raw.

Vidalias are famous for their sweet mild flavor, people even eat them like apples. I slice them into very thin strips and they cook up perfectly in the oven, retaining just a hint of crunch and a fresh sweet onion flavor. The dip has a very appealing creamy white color, too, under the lightly browned crust.

Customize this onion dip recipe to what you’ve got in the fridge

Nothing is set in stone here, the ingredient amounts are flexible, as are the types of cheeses. Just be aware that the stronger the cheese, the more flavor you’ll get. If you use Monterey Jack and mozzarella, your dip will be on the bland side. A good rule of thumb is to add some kind of aged Italian cheese, in the Parmesan family, to the mix because they are very assertive. I found Grana Padano, which is similar to Parmesan, so I used that.

I make this cheesy dip with the chop and drop method

Everything gets thrown into a bowl and mixed together. You can do it way ahead of time, just cover it and pop it in the fridge. It’s got all the earmarks of the ideal party appetizer, but I think it’s just as good a choice for a romantic evening for two. I’ll definitely be making this during the holiday season, it’s so warm and comfy. Love.

“My husband was given a 10lb bag of Vidalia onions as a gift. I’ve been making many of the recipes that you featured here and this one is his favorite! I followed your recipe to the letter and he said that it was the best dip he’s ever had. Thank you! (And as I write this, your quiche is baking in the oven. Looking forward to that, too!) Will definitely make again.” ~Sarah

  • 1 Vidalia onion, anywhere from 10-12 ounces (any sweet onion variety will do)

  • lots of fresh cracked black pepper to taste
  • 4 dashes hot sauce

  • Set the oven to 375F
  • Peel and slice the onion in half. Then slice it in half again, and cut 3 of the sections into very fine slices. Take the last piece and mince it. Put the onion in a bowl with the rest of the ingredients and mix well until everything is thoroughly combined. Taste and adjust the seasonings to your liking.
  • Spoon the mixture into an ovenproof casserole and bake for 25 minutes until browned and bubbly.
  • While the dip is baking, slice a baguette and place the slices on a hot grill pan to toast them on both sides. Serve with the hot dip.

    Sounds great! Could this be made and cooked in a crockpot? Has anyone ever tried that? Looking to take to a party that way

    I’ve only got time/room for one baked
    onion dip. So Carmelized Onion dip or
    Vidalia Onion dip? Which one first?
    Thank you for all your wonderful recipes.
    Go Buccaneers!!

      Haha, well, honestly they’re both equal, but if it helps, the caramelized onion dip is incredibly rich, whereas this one is a little lighter. This one needs some sort of sweet onion, the other one does not. The caramelized dip also takes a lot more time to cook down those onions, but it’s worth it 😉

        I’m on a low-carb diet, would veggies work as a dipper for this dip? Any suggestions???

          Great question ~ carrots and celery probably wouldn’t work too well, but I wonder if you could spoon it into endive leaves, or something like that.

          I was thinking it would be delicious as a topping for chicken breasts or roast beef with maybe some baked broccoli on the side.

            Yes, you could even bake chicken in it!

    This looks delicious! I’m thinking of making this as a Thanksgiving hors d’oeuvre. Can any part of this be made ahead? Thanks!

      You can make the dip ahead, before baking, and refrigerate. Then set out on the counter for an hour to bring up to temperature before baking.

    Does this have a lot of grease after cooking? I’ve made one before (very similar) and it was pooled with grease. The dip was amazing, but the grease was such a turn off. Please advise??

      No, it shouldn’t be greasy, sometimes that can happen with creamy dips if they’re baked too long.
