Skillet Onion Dip

One of the first dips I remember loving with chips was French Onion Dip. In fact, it was the only dip I would eat! I have tried other dips since I was a kid, and I love a lot of them. Cold dips are great with veggies and chips, but hot dips seem to be the hit of most parties nowadays. In fact, I was just with some friends over the weekend, and this dip was gone in a matter of minutes. The veggie tray with cold dip was untouched until all the Skillet Onion Dip was gone! This hot dip brings me back to my French Onion Dip days but definitely makes me feel more ‘adult’.  There really isn’t a limit on dip options, so the more varieties, the better!

Best of all, you can use a cast-iron skillet for most of your cooking, including this Skillet Onion Dip. And don’t go out and buy one just because they are back ‘in vogue’. Buy one because they have been around for a couple of thousand years and they work!

I’m done with the cast-iron endorsement, but did you order one yet?😉 Anyway, once you have the ingredients on hand, it’s so easy to have this dip ready to share.

How to Make Skillet Onion Dip

Skillet Onion Dip is really so easy that you could easily add this to your go-to recipes when you have company over or are simply hanging out with your family on movie night! First, preheat the oven to 350°F. Next, finely dice your Vidalia onion. Now, what does dicing the onion actually mean? There isn’t a whole lot of difference between chopping and dicing an onion other than appearance and size. In this case, just dice the onion as small as you can.

How to Dice an Onion

Here are some tips to help you cut up your onion.

  1. Choose a sharp knife, and use the middle of the knife where it is usually the sharpest.
  2. Cut the onion in half, pole to pole, and lay each half cut side down on your cutting board.
  3. Peel the onion, and cut the halves of the onions horizontally as many times as you can. Leave a little room on the end; don’t cut all the way across. The closer the cuts, the smaller the pieces you will have.
  4. Next, make several cuts vertically (from pole to pole).
  5. Finally, slice across your cuts, and you will have your diced onion! Good job!

PRO TIP: The size of the onion will help you determine how many you need to buy for your next recipe. I used 2 cups diced Vidalia onions for this dip, which means I could use 2 medium-sized onions (2 1/2 to 3 inches in diameter) or 1 large onion that measures about 4 inches in diameter.

Now that the dicing is out of the way, mix all of the ingredients together in a large bowl until everything is well combined. Transfer the mixture into your skillet and bake for about 35-40 minutes. The dip should be hot and bubbly when you take it out of the oven. Wait about 10 minutes before you dig, I mean dip, in!

Dip in!

We loved this dip with toasted baguettes, but it would work well with crackers and grilled bread, too. If you wanted a lighter version of this addicting dip, you could use light mayo and light sour cream.
