Caramelized Onion Biscuits

RATE IT

Yields about ten 2-3/4-inch biscuits or eighteen 2-inch biscuits

  • 2 large yellow onions, halved lengthwise, trimmed, and thinly sliced lengthwise
  • 1 Tbs. vegetable oil
  • 3 Tbs. granulated sugar
  • 1 Tbs. balsamic vinegar
  • 8 oz. (1-3/4 cups) unbleached all-purpose flour; more as needed for shaping the dough
  • 2-1/4 tsp. baking powder
  • 3/4 tsp. kosher salt
  • 1/4 tsp. baking soda
  • 4 oz. (8 Tbs.) very cold unsalted butter
  • 3/4 cup very cold buttermilk
Cook the onions:

At least a few hours and up to a day ahead of making the biscuits, put the onions and the oil in a large skillet over medium heat and cook, stirring occasionally, until they are soft and translucent, 8 minutes. Add 2 Tbs. of the sugar and the balsamic vinegar, and continue cooking and stirring until the onions are very soft and caramelized, 10 to 15 minutes. If the onions brown too much or the bottom of the pan gets too brown before the onions are soft, add some water, about 2 Tbs. at a time. Let the onions cool at room temperature for 30 minutes, chop coarsely, transfer to a container, seal, and refrigerate until cold.

Mix the dough:

Heat the oven to 500°F and position a rack in the middle of the oven. Line a rimmed baking sheet with parchment. Put the flour, remaining 1 Tbs. sugar, baking powder, salt, and baking soda in a large mixing bowl and stir with a whisk to distribute the ingredients evenly.

Cut the butter into small bits and toss with the flour. With a sharp knife or a bench knife, cut the cold butter crosswise into 1/4-inch-thick slices. Stack 3 or 4 slices and cut them into three even strips. Rotate the stack a quarter turn and cut the strips in half. You should create 6 small bits of butter per slice. Toss the butter bits into the bowl with the flour mixture. Continue cutting all the butter in the same manner and adding it to the flour mixture.

When all the butter is in the bowl with the flour, use your fingers to separate the butter bits (they tend to stick to each other), coat all the butter pieces with flour, and evenly distribute them throughout the flour mixture. Don’t rub the butter too hard with your fingertips or palms, as this will melt the butter. You’re just trying to break the butter pieces apart, not blend the butter into the flour.

Give it a little stir. When all the butter is evenly distributed, add the cold buttermilk and stir with a large spoon until all or most of the flour is absorbed by the buttermilk and the dough forms a coarse lump, about 1 minute.

Pat and fold the dough:

Pat and fold the dough. Dust a work surface with flour and dump the dough onto the floured surface, cleaning out the bowl with a spatula or a plastic bowl scraper. Dust the top of the dough and your hands with flour, and press the dough into a 3/4-inch-thick rectangle. Sprinkle a small amount of additional flour and one third of the caramelized onions on the top of the dough. Fold the dough over on itself in three sections, as if folding a letter (also called a tri-fold). With a bench knife or metal spatula, lift the dough off the counter and dust under it with flour to prevent sticking, if necessary. Dust the top with flour and press the dough out again into a 3/4-inch-thick rectangle. Sprinkle on another third of the caramelized onions and repeat the tri-fold. Repeat this procedure one more time (three times in all), with the remaining caramelized onions.

Cut and bake the biscuits.

After the third tri-fold, dust under and on top of the dough, if needed, and roll or press the dough into a 1/2-inch-thick oval. Dip a 2-inch or 2-3/4-inch round biscuit cutter in flour and start cutting biscuits, dipping the cutter in flour between each biscuit. Press straight down to cut and lift straight up to remove; twisting the biscuit cutter will seal the sides and interfere with rising. Use a bench knife or spatula to transfer the biscuits to the baking sheet, placing them about 1/2 inch apart.

Gently gather any scraps of dough, pat and roll out again, and cut more biscuits from the remaining dough. You can gather and roll the scraps two times total and still get good results (the more times you roll out, the tougher the biscuits will be).

Put the baking sheet in the oven and reduce the temperature to 450°F. Bake for 8 minutes; rotate the pan 180 degrees; continue baking until both the tops and bottoms of the biscuits are a rich golden brown and the biscuits have doubled in height, revealing flaky layers on the sides, 4 to 6 minutes more. It’s all right if some butter seeps from the biscuits. Remove the pan from the oven and set it on a cooling rack, leaving the biscuits on the pan. Cool the biscuits for at least 3 minutes and serve them hot or warm (they will stay warm for about 20 minutes).

Though my family teases me about being a terrible baker,they ate every crumb of these biscuits! The technique is spot on and the flavor of the caramelized onions is amazing.
