Caramelized Onion Buttermilk Biscuits

Caramelized onions mixed into buttermilk biscuits?! Yep! I love this added twist to homemade biscuits, and it’s super simple to do. I’m not one to make homemade biscuits very often, it’s easy to reach for the refrigerated can, and rightfully so, they’re delicious and convenient. But, if you’re looking to try something new, and enjoy the satisfaction of baking with simple ingredients then definitely give biscuits a try! They’re an easy beginner level baked good.

I’m a huge fan of caramelized onions, so so good! They’re so flavorful and simple to make, slice them, and slowly let the stove do the rest, it’s that simple! I love making a big batch to have on hand, perfect for topping burgers!

It was so cool to actually see all those flaky layers when you take them out of the oven, flaky layers that YOU made!

Golden, crispy edges with warm, savory, flaky centers. These beauties belong on your brunch, lunch, or dinner table! They also make for an epic breakfast sandwich in the morning!

Serve these along side a couple of my favorite meals here!

Servings 12 biscuits
Author Laura Doerr


For the caramelized onions

  • 2 sm-med yellow onions chopped
  • 2 tbsp unsalted butter

For the biscuits

  • 2 cup all purpose flour
  • 2 tsp baking powder
  • 1/2 tbsp sugar
  • 1/2 tsp baking soda
  • 1 tsp salt
  • 7 tbsp unsalted butter chilled in freezer, cubed
  • 3/4 cup buttermilk plus extra for brushing


For the caramelized onions

  1. Add chopped onions and butter to a large skillet and cook over medium-medium low heat for about 20-30 minutes or until golden brown, soft and sweet. Season with salt and pepper and let cool.

For the biscuits

  1. Preheat oven to 400 degrees.

  2. In a large bowl, whisk together the flour, baking powder, sugar, baking soda, and salt. Cut the cold butter cubes into the dry ingredients with a pastry cutter or fork until mixture becomes coarse crumbs.

  3. Make a well in the center of the bowl and pour in the buttermilk and cooled caramelized onions, and stir until just combined. Dough will be sticky.

  4. Flour a work surface, and turn dough onto the work surface. Create a dough ball and press into a rectangle, fold dough over itself about 4 times, that will create the flaky layers. Roll dough out about 3/4-1 inch thick. Cut with a 3-inch biscuit cutter. Repeat until all the dough is used, you should get about 12 biscuits. 

  5. Place biscuits on a parchment lined sheet pan, and brush with buttermilk. Bake for about 15 minutes or until golden brown. Serve warm. Best enjoyed the same day.
