Hot Cream Cheese Onion Dip Recipe
I used to say I hated onions, but I guess I don’t because I loved this dip. It’s ridiculously good and dangerously easy to make.
Given what’s in it, it’s impossible that it would be bad. We’re talking pure, unadulterated comfort food. It’s fattening, full of sodium, creamy and rich, with some soft texture from the onions, and a tiny bit of heat to keep you going back for more.
Because I used a sweet Vidalia onion, it’s not overly ‘oniony’. Of course, there’s onion flavor, but in a good way, not in a I just ate onions and cannot be around others who haven’t for at least two days type way.
I added a pinch of cayenne and it provides some very gentle heat, but if you’re not into heat at all, omit it.
I’m a dip lover extraordinaire. As in, I can skip the entree and just eat dip at a restaurant or a party, and this is exactly the kind of dip that’ll make me do it. After a pound of cream cheese and cheese, who needs anything else?
It reminds me a lot of Loaded Baked Tater Tot Dip, minus the tater tots, and incorporates elements of various onion dips and spinach and artichoke dips I saw online.
It’s a perfect dip to serve for game day as an appetizer, at any dinner party, as a Thanksgiving or holiday side dish. Or, just make it just because it’s Wednesday night.
After we gorged on half the batch, I put the remainder into an airtight container, refrigerated it, and the next day nuked it for a minute and it was good as new!
What’s in Baked Onion Dip?
To make this cream cheese onion dip, you’ll need:
- Cayenne pepper – You can omit this if you aren’t a fan of spice
- Cream cheese – I used low-fat cream cheese but full-fat cream cheese will also work. Make sure to use brick-style varieties, not cream cheese from a tub
- Mayonnaise – Again, I used low-fat mayo to keep this recipe a bit lighter, but full-fat mayonnaise is also great
- Cheese
- Sweet Vidalia onion
- Salt and pepper

Recipe FAQs
I used Kerrygold’s Blarney Castle cheese, but almost any cheese or shredded cheese blend from Parmesan cheese to Swiss cheese to a 4-cheese blend will be lovely. It’s cheese. There’s no wrong answer.
You could add a couple of handfuls of frozen spinach and artichokes to make onion-dip-meets-spinach-and-artichoke-dip. I’m going to try that next time. You could add a cup of corn, beans, or pre-cooked rice, too, to beef it up.
Yes! Feel free to sauté yellow onions to make caramelized onions before stirring them in with the rest of the ingredients.
I haven’t tried it, but you could probably use vegan products for the cheese, cream cheese, and mayo.
Yes! You can assemble the dip, cover it with plastic wrap, and chill until you’re ready to bake it off.
This hot onion dip is best served fresh and warm, but leftovers will stay fresh in an airtight container in the fridge for up to 5 days. Gently reheat it in the microwave before serving.

thanks (and your comments were going into mod b/c you put that HTML code in – you don’t have to do that in the future)
Yum! I definately think this is worth the calories!
Oh yum! I’ve always loved onion dip, even when it isn’t oozing with warm, melted cheese. I have a feeling that I could eat the whole dish myself…and then need to run a marathon to make up for it!
The marathon part. Yeah, I hear you :)
This looks fantastic! I could eat that entire bowl. I love onion dips so much, I even put one in my book. Fabulous job!
Ok I have your book and now I need to go look it up! And your spinach dip today…I want to marry our two dips and live happily ever after!
I love dip too, it’s just that much more fun to eat when you get to use your hands. This one looks awesome and perfect for holiday parties. I have the same pyrex glass dish :-)
I’ve had this Pyrex for at least 15 years. My mom gave it to me when I was in college and it collected dust for a good 5-7 before I started using it :)
You had me at double cheese! This dip has to happen soon! Pinning!
thanks for pinning :)
Okay, I’m not an onion fan either (I think we discussed this) but who can resist cheese and spices melted in one happy union! Besides, Vidalia onions are not That bad. :D
My husband hates onions, but they are my absolute favorite. I’ll have to make this dip when he’s out of town and eat it all by myself haha!
Um, okay that didn’t work. Anyway, my wish is to cram my face into that entire plate. Happy Thanksgiving!
My Thanksgivi
Cheesy baked onion dip is a new favorite for me too! I just got into onions this year, but I love them most caramelized (extra step, but so good!) and with lots of cheese! I am still looking for recipes tomorrow and this looks awesome for an app!
Serious comfort food indeed–and I was thinking that some corn or spinach would be really good in there too! Love your choice of gouda. This is the type of dish my husband’s family would go for– they all love cheese. We’re getting together over the weekend so I may just bring some of this–it can bake while I’m getting my salad together.
Paula they will love you even more if you bring this. Seriously…soooo good. You can pre-assemble at home and just bring and bake. (traveling with onions is a little stinky..LOL) But I am not even usually into serious onion and cheese stuff like this – normally the dips I like have more veggies and texture, but that all went out the window with this one :)
Oh man this looks amazing! I would love to have this New Year’s day when we are all relaxing in the house, watching football, and snacking!
Sounds like a perfect plan!
Oh my goodness, you had me at creamy, cheese and onion! Those are 3 words that can never be wrong in one sentence together. This dip looks like pure comfort in a baking dish! Plus, I love how easy it is. Pinned!
Thanks for pinning and yes, it was pure comfort in a dish. So.good.omg.
Talking about comfort food! This dip is seriously something to warm the heart and fill the tummy. I would totally make this for me and Jay, if he wasn’t lactose intolerant… guess that’s not worth the fun ;) instead I will wait for the girls to come around to enjoy this with some baguette and vino. Perfection!
You could probably buy vegan products for the cheese, cream cheese, and mayo (Daiya, Toffutti, and Veganaise) and try it out!
