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.
