Table of Contents
This super easy recipe for the Best Hot Onion Dip will become your go-to quick appetizer recipe!
Dip Ingredients
- Vidalia onions
- Cream cheese
- Mayonaise
- Parmesan cheese
- Black pepper
Pro Tips
- Room temperature cream cheese works best, if you are in a rush, remove it from its packaging, place on a plate and microwave for 30 seconds or so to soften.
- A fresh Parmesan cheese wedge is best for this recipe or you can use the shredded Parm in the deli section in plastic round containers.
- Hellman's or a traditional mayo works best, not the sweeter Miracle whip.
- Do not use low fat products for this recipe, use full fat.
- Do not make your oven temp higher than 350, you will run the risk of the cheese breaking and becoming oily.
- Leave this onion soufflé dip in the oven until the top browns (if you want it that way), vs using the broiler for the same reason. You don't want the cheese to break.
Low carb appetizer recipe
THIS! This Hot Onion Dip made with just 5 ingredients to make (really just 4 but I am counting the black pepper). You can have it mixed and in the oven in literally 5 minutes flat. About 5 carbs for a 4 ounce serving (picture half of a cream cheese brick). Serve with low carb veggies or crackers.
Onion Dip Variations
- Add in jumbo lump crab.
- A couple TBS of minced jalapeno's can be added for a nice kick.
- You can add-in frozen, thawed spinach that has been squeezed dry or chopped artichokes that have been blotted dry.
- Swap the cheese for Colby Jack or Pepper Jack or do half Parm and half one of those.
Instructions
- This is literally one of the easiest part appetizers or snacks you will ever make!
- Just dump 1 cup of mayonnaise, 1 cup of Parmesan cheese, 1 (one) 8-ounce package of cream cheese (softened), 1 chopped medium onion (about 1 ¼ cups) and a good amount of black pepper into a bowl and mix until combined.
- Scrape the mixture into a small casserole dish and bake for 25-30 minutes at 350 degrees. YUM!
- Serve with raw veggies, French bread, crackers or my favorite way with flat pretzels like Snack Factory Pretzel Crisps, YUM!
I hope you LOVE this super simple yet seriously delicious onion dip as much as my family and friends do! I first shared it in 2012 on the blog and have been making it years before that. I found it from White on Rice Couple many years ago.

The BEST Hot Onion Dip
Ingredients
- 1 8 oz package of cream cheese softened (as a gal from Philly, I adore the one and only Philly Cream Cheese)
- 1 cup mayo
- 1 cup shredded Parmesan cheese
- 1 medium Vidalia onion diced (about a heaping cup full)
- 1 teaspoon pepper
- Serve with pretzels slices of crusty bread, or crackers
Instructions
- Preheat oven to 350 degrees. Combine all the above in a bowl and mix until smooth.
- Scrape into a baking dish. Bake for about 30 minutes (give or take) or until the top browns in spots.
- Note: Don’t cook at higher than 375 degrees or you run the risk of separating your cheese which will make the dip greasy. For best results, don’t use low-fat anything. When making this Hot Onion Dip, you’ve got to live it up!
Cindy @ The Sweet Nerd says
Only needing 5 ingredients is awesome - especially on a game day. Super cheesy and gooey - love it!
Tara | Deliciously Declassified says
Love a quick and easy dip that's a crowd pleaser. This one looks delicious! Also Mike's Hard Lemonade brings back great summer memories. Thanks for sharing.
Jillian says
Super easy & super cheesy - two of my most favorite things!
Chichi says
Hmmm. This certainly looks like something I would love. I would have to google what Vidalia onions though. Can I use any other onion? Thanks for sharing
Ellen says
So much cheesy goodness and only 5 ingredients! Perfect for game day or a small holiday gathering.
Rob says
I just made this and LOVE LOVE LOVE IT! I did tweak it just a bit buy adding a smashed garlic clove and a quarter cup or so of feta cheese. Its incredible! Thanks
Colleen says
I LOVE this dip as well! I am totally trying your tweaks next time. I have literally made this 50 times in the last 6 years or so, so a little change would be fun! Thanks Rob!
Vicki Roberts says
This was amazing!!!! Next time I will double the recipe. I added parsley and garlic just because I could LOL . My son (who is 34) ate half all by himself. It was great with heavy crackers and even veggies. Okkkkkk... it was great by the spoon tooooooooo! This is now my go to take along or last minute dip for visitors! I may have to make more today... they left me one tablespoon!!!!
Misty says
I didn't cook it at a temperature higher than 375° but mine turned into a greasy mess. I also didn't use low fat ingredients. Not sure what I did wrong.
Kristin says
Philadelphia cream cheese didn’t come from Philadelphia. It was invented in NY.
Colleen says
How about that! Thanks for the education!
Jessie says
Love this dip, thanks for sharing. I sliced my onion (had to use a sweet onion) and then sautéed it in olive oil and garlic until lightly browned. I let it cool before I added to the rest of the dip mixture. After baking, I did a few minutes on broil, too. This dip is definitely going into the rotation! (I also enjoy a Mike’s Hard Lemonade :)).
Colleen says
SO then more of a caramelized Onion DIp I guess?? Sounds delicious! This is a family and friends favorite!
Patty says
Can this be made a head of time & refrigerated? Two days? Then put in a baking dish and baked?
I've made it and everyone loves it, but I'm time crunched on the actual day an trying to make things ahead of time.
Colleen says
Hi Patty, I am going to go with no. I have never done that however I just know it would not have the souffle-like texture it does when fresh.
texasgirl says
Soooooo good! And my house smelled amazing while it was baking too! My husband and I polished this off with noooo problem. Served with SunChips, and carrots because that's what we had on hand. Delish!
Colleen says
So fantastic to hear that (love me some SunChips too)! Thanks for the stars!!
Jon says
Im going to try this next spring when the wild leeks ( ramps ) are in season.
In the meantime ill try it with just onions, seems like a good football watching treat
Colleen says
Yes!!! Ramps are a gift from the gods for sure! I search every year and have never found them wild. BUT I did plant a handful of bulbs from my haul in 2019 from a forager at a local pop up farmers market and THEY CAME UP this spring!! Hoping they will one day germinate! and I will have more and more, fingers crossed! This dip truly is simple yet spectacular. As long as you don't use low fat anything (IMO) and don't heat it too high and break the cheese. It's amazing! Enjoy!
Bonnie says
Can this be put together then frozen before baking?
Colleen says
I have not done that, I am going to go with no. I just don't think it would work well. I could be wrong, if you do try it with success let me know.
Kim says
Can this be made in a small crockpot?
Colleen says
I have never done that Kim, Would that enable the top to brown a bit? As long as the cheese doesn't get too hot and "break" If so try it. I have never cooked in a crock pot, I have only used a small one to keep warm dips warm.
Missy says
Tried this recipe over the weekend for a football party…it was a hit! Just added a little feta & topped with everything bagel seasoning. Great recipe, thanks for sharing!
Colleen says
fantastic! Thanks for your twist!
Kathy Grimes says
Can 5his be nade in crockpot?
Kathy Grimes says
Sorry about the last post mis spelled words- can this be made in a crockpot?
Colleen says
I have not and honestly only have used a small one to keep things warm in the past. The oven gives it a bit of browning on top which is delish. You can certainly try, just be sure its not too hot and the cheese breaks.
Samantha says
party winner! absolutely delicious and feel like a real food snack!
Colleen says
AWESOME!!
Jody says
What a great recipe!!! It has been added to our 'Go-To' List!! 😉 Have you ever frozen it? Thanks!!
Colleen says
Great to hear! I have not frozen it. I would worry about too much moisture from the ice crystals that would form. However I am not a freezer of many prepared foods, so worth a try.
Donna says
SO good! Made this for 4th of July and it was a hit. We think we like it better than the standard caramelized onion dip and it was so much quicker to make. Used 1/2 of a large purple onion and it was excellent!! Definitely on the favorite list! 😋
Colleen says
Fantastic to hear! Glad it was a hit Donna!
