    Baked Caramelized Onion Dip with Gruyere Cheese

    Hot, bubbly, and delicious! This Baked Caramelized Onion Dip with Gruyere Cheese is absolutely insane! Well, not insane like Lizzie Borden, this is the type of insane your family will love!

    I don’t believe there is a single ingredient that makes a more transcendent transformation than a simple onion when it is caramelized. There is something magical about the flavors that are gently coaxed out of the onion during its long vacation in the sauté pan. The final product forms the base of quite possibly the most luxurious dip to ever kiss your lips!

    You need caramelized onions for my Baked Caramelized Onion Dip with Gruyere Cheese recipe, but don’t worry, just click this link to learn how to make caramelized onions.  The amount of onions called for in that recipe perfectly matches what is needed in this recipe.

    Baked Caramelized Onion Dip with Gruyere CheeseThe final product will yield a cheesy Baked Caramelized Onion Dip with just the right amount of creaminess and more flavor than you would believe! This is a recipe you’ll want to keep in your back pocket for when you are looking for an appetizer that will impress!

    I used an eight inch cast iron pan to bake this dip.  However, any similar sized oven safe baking dish will suffice. Though, I find the smaller cast iron pan has a rustic look that perfectly matches the dip.

      We have a potluck coming up and the theme is Baked Potato toppings and I would really like to bring something other than the typical toppings. Do you think this would pass for that?

      Made this for a holiday party. Everyone raved! I am going to be a Karen.....in step 3, it should say "Top with 1/2 CUP of cheese", no? Perfectly understandable without that addition but, I'm an English major and a foodie.....dangerous combination, LOL! This recipe is going in the "Family Favorites" file!

      When you say cup of cheese is that 8 ounces or a measuring cup.

        I haven't measured it exactly, but a 9 x 13" baking dish should work well, if you pour the mixture in it and find it is too big, just grab a smaller pan. Making the onions a day ahead isn't a problem at all.

          This recipe is being saved and made at every holiday! Such a hit! I made the onions the night before which was such a time saver. Just mixed and baked when I needed it.

          I must have put too much cheese on the top or cooked a little too long though because my cheese split and got oily/clumpy on top.

          So delicious! Making again and sending the recipe around!

      OMG! Thank you for such a fabulous recipe. We were asked to bring a cheese appetizer for Thanksgiving with neighbors because another of their friends always brought wonderful crusty bread. Needless to say it was a great pairing. Also made the Reuben dip which was also a hit. Mixing up the triple chocolate snicker cookies now and can't wait to try more of your recipes. You are a great Foodie!

      This sounds delicious. Is there any reason why I couldn't make it as written and then reheat it in the microwave for a minute or so before serving. I'm thinking of taking it to an event some distance from home.

        Melted cheese typically does not reheat well. It will lose much of it's creaminess and break into an oil slick. It would still taste good but not great.

      The flavor is unbelievable . I used it as a filling for mini Caramelized Onion pies. Just use the premade frozen ones if you don't have time to make them. Seriously delicious.

      Made this last weekend and it was enjoyed by all. Used an oven safe dish as I don't have a small cast iron pan.

      I make caramelized onions at least 1-2 times a week but I sprinkle a little sugar on once they start to brown. And when in season, I use Walla-Walla onions or Maui onions, when I can find them !! Soooooo delectable on anything and everything !!! Thank you for ALL of your wonderful recipes, your site is my favorite. I am 72 yrs. and have been cooking for family and friends since I was 18, have a bazillion cookbooks, but you teach me something new all the time !!!! Thanks Again and STAY HAPPY !!! Sheila M. PS> Meant to say I make the onions 1-2 times a MONTH !!!! Although I could Make them 1-2 times a week and still want more !!! Wish I had a recipe good enough to share with YOU !

      I'm with you, caramelized onions are a gift from above. I kid you not, I think I'd eat a piece of cardboard if it had caramelized onions on it. This dip looks INCREDIBLE, and I can't wait to share it at the next potluck!
