Why We Love This Hot Onion Dip Recipe
There’s nothing better than a great appetizer dip and this hot onion dip is perfect. With football season coming to an end (hello Super Bowl!), and New Year’s Eve upon us… good dips are a great thing to try. This best-ever baked onion dip recipe is a must!
- Easy. Just mix the ingredients together, bake, and serve.
- Cheesy. With cream cheese, Boursin, Parmesan, and Gruyere, this dip is absolutely stuffed to the brim with gooey cheese.
- Flavorful. The onions blend seamlessly into this dip for a rounded flavor that’s not overwhelming. Even onion haters love this dip!
Variations on Baked Onion Dip
For a stronger onion flavor and a slightly sweeter dip, try caramelizing the onions first! If you can’t find Boursin, try mixing more cream cheese with fresh herbs. You can also experiment with different types of cheeses, like cheddar, emmental, comté, mozzarella, or provolone!
How to Store and Reheat
Store leftover hot onion dip in an airtight container in the refrigerator for up to 5 days. It tastes great cold straight from the fridge, or reheat it in a 350°F oven for 7-10 minutes.
Serving Suggestions
We served this cheesy hot onion dip with crackers and sliced veggies. Just keep it simple! But it would also be great with pita chips or little pieces of toasted bread, or on top of baked potatoes.

Made this for my sister’s baby shower. A HUGE hit! It went fast. I should have doubled the recipe!
oh i’m so glad! this is one of my favorites. glad they liked it!!
I never came back to say it was SO tasty!!! I’m making it again tonight with smoky gouda for my Downton Abbey Season finale shindig…I know, I know…not so much English….but it’ll be delish so no one will care :)
i’m so glad you liked it!! and last night sounds like a great reason to make it :). that sounds amazing with smokey gouda…i’ll have to make it like that next time
Alright Becky, when I saw that your directions said “pour,” I started to get concerned because the mixture I had was way to thick to pour. Sure enough, when it was done baking, not at all liquid or runny like your pictures. What did I do wrong???
I think it will be fine. We just heated up the cream cheese to make it easier to mix. It should be the same once you bake it. 99% sure. Although I’m still def no expert :)
Awesome!! Let me know if you like it! I’m always honored when you try stuff because you’re such a professional!!
I would be flattered if you thought I was a professional, but I think this is a misplaced reply hahaha
oh, yes that was actually supposed to go to angela. but of course i think you’re a pro as well michael!
Hey Michael, this is Susie (Becky’s mom) and she asked me to clarify. The onion souffle should be firmer than our pictures. For some reason, this one time, it turned out a little less firm than usual. We didn’t actually heat the cream cheese before mixing, but we did let it come to room temperature before mixing. I hope this helps and explains. If yours did came out firmer, it is probably perfect. We will be sharing Onion Souffle Version II very soon, so we will keep you posted. Thanks so much for checking out our recipes.
Thanks for the help! Heather assures me it was tasty, so I am satisfied!
:) glad it worked out! happy wife, happy life!
We just put ours in the oven!!! I’m excited to try it…we used smokey gruyere, a house fav :)
