This Hot French Onion Dip is creamy, cheesy and gooey with the most delicious French onion flavor that is sure to become your new go-to appetizer!A CREAMY AND WARM APPETIZERMade with caramelized onions, melty cheese, and a creamy base, this baked dip is based off French Onion Soup (and boy is it GOOD!) This dip is the ultimate crowd-pleaser. I think even folks who dont consider themselves fans of onions, love this dip. And if youve never made caramelized onions at home, I am going to show you how easy it is. It really transforms the flavor of the onion to something so soft and almost sweet. It may look hard to make or like a fancy appetizer, but this dip is really so simple to make the hardest part is just waiting for those onions to caramelize!FREQUENTLY ASKED QUESTIONS:Can I make this in the Crock Pot? I believe you should be able to keep this warm in a slow cooker. Just follow the directions for caramelizing the onions and add the cream cheese. Then pop it all in a small slow cooker and add the cheese and then put on low to finish cooking then turn it to warm.This will help keep it warm for serving, especially if you are serving this at a gathering. Can I make this dip without a cast iron skillet? Yes! You can caramelize the onions in any skillet, then transfer the mixture to an oven-safe dish like a pie pan orsmall casserole dish for baking.I just find that the cast iron skillet seems to work best for even heating. How do I caramelize onions faster? Caramelizing onions properly takes time, butI was taught that adding a pinch of sugar and a splash of water or broth can help speed up theprocess slightly. However, avoid rushing, as low and slow cooking really does give the bestflavor. Use medium to low heat to ensure the onions caramelize slowly and evenly withoutburning. This can take 20-25 minutes, but the deep flavor is worth it.Also, you should stir occasionally, but not too frequently, to allow the onions to develop color. What are some good dippers for this recipe? Great dippers include baguetteslices, pita chips, pretzels, tortilla chips, crackers, or fresh veggies like celery,carrots, and bell peppers. What else can I add? You can mix in cooked baconbits, chopped spinach, or even a dash of hot sauce for a twist. Can I make this dip ahead of time? Yes, you can assemble the dip up to a day inadvance. Cover and refrigerate it, then bake it when youre ready to serve. If bakingdirectly from the fridge, add 5-10 minutes to the bake time. Can I substitute the cheeses? Absolutely! Gruyre adds a creamy, nutty flavor, but you can use mozzarella, Swiss, cheddar, fontina, or even Monterey Jack. A mix of cheeses can also add depth to the flavor. Can I use pre-caramelized onions or onion jam? Yes, if youre short on time, youcan use pre-caramelized onions or onion jam from a jar. Just make sure to adjustthe sweetness of the recipe, as some onion jams can be quite sweet.I havent tested it myself so youll kind of have to play with the amount to use. Add a little at a time then add more to your taste. How do I store leftovers? Store leftovers in an airtight container in the refrigeratorfor up to 3 days. Reheat in the skillet or microwave until warmed through.
