I made this recipe a few times throughout the holiday season. Once for Thanksgiving and my momma made it for our Christmas gathering. It was a hit both times! Putting this recipe together was a little difficult for me. I usually don't follow recipes to a 'T', and like to go off the look and taste of a dish. So, feel free to adjust as needed! Warning: Once you start eating you can't stop!
6-8 Onions (depending on the size - I like to go a little heavy on the onions since they shrink in size after cooking for so long)
1/3 Cup Brown Sugar
2 Tablespoons Balsamic Vinegar
2 Tablespoons Butter
1 Cup Parmeson Cheese
1-2 8 oz packages Cream Cheese (depending on the size of crowd you are feeding)
3/4 Cup Mayonnaise
1/2 Cup Sour Cream
1 Teaspoon Mustard Powder
1 Tablespoon Worcheshire
2-3 Tablespoons Sriracha (depending on how spicy you like it)
Preheat oven to 350 degrees.
Slice onions and put in pan with olive oil and 2 tablespoons butter. Let onions start to caramelize and brown about 5 minutes. Sprinkle with salt and pepper, brown sugar and balsamic vinegar. This process can take some time. Anywhere from 30-40 minutes or longer if you want a deep, caramelized onion jam. If you're impatient like me, I like to cover the pan to speed up the process a little bit. ;-)
While the onions are caramelizing I get the base mixture together. Throw in the cream cheese, mayonnaise, sour cream and parmesan cheese in a mixer and mix until blended. Add mustard powder and worcheshire. Once the onions are done let cool 5-10 minutes, and add to the base mixture. Lastly, add sriracha sauce. Taste and add additional ingredients as needed.
Put in buttered pan, sprinkle with parmesan cheese and bake for 15-20 minutes until brown on the top.
Serve with crackers or warm bread. Enjoy!
