Caramelized Onion Butter Board (Print Version)

Silky golden onions blended into creamy butter, spread on a board and topped with herbs. Ideal for crackers and baguette slices.

# What You'll Need:

→ For the Caramelized Onions

01 - 2 large yellow onions, thinly sliced
02 - 2 tablespoons unsalted butter
03 - 1 tablespoon olive oil
04 - 1/2 teaspoon kosher salt
05 - 1/2 teaspoon sugar
06 - 1/4 teaspoon freshly ground black pepper

→ For the Butter Board

07 - 8 ounces unsalted butter, softened to room temperature
08 - 1/2 teaspoon flaky sea salt, plus extra for garnish
09 - 1 tablespoon fresh chives, finely chopped
10 - 1 teaspoon fresh thyme leaves (optional)
11 - Freshly ground black pepper, to taste

→ For Serving

12 - Crackers, for serving
13 - 1 baguette, sliced

# Steps to Follow:

01 - In a large skillet over medium heat, melt 2 tablespoons butter and olive oil. Add the sliced onions and sprinkle with kosher salt and sugar. Stir well to coat.
02 - Cook onions, stirring occasionally, for 35-40 minutes until deeply golden and caramelized. Reduce heat if onions brown too quickly. Season with black pepper. Let cool to room temperature.
03 - In a medium bowl, mix the softened butter with half the caramelized onions, 1/2 teaspoon flaky sea salt, chives, and thyme (if using) until well combined and spreadable.
04 - Spread the butter mixture evenly onto a large serving board or platter using a spatula or the back of a spoon. Swirl for texture.
05 - Spoon the remaining caramelized onions over the top. Sprinkle with additional flaky sea salt, extra herbs, and freshly ground black pepper.
06 - Serve immediately with crackers and baguette slices.

# Additional Tips::

01 -
  • The way those onions melt into butter creates something that tastes like it came from a restaurant kitchen
  • Its the kind of appetizer that makes people linger around the board longer than they planned
02 -
  • Caramelizing onions takes patience and low heat, so resist the urge to crank up the temperature
  • The butter mixture needs to be room temperature or slightly cool before spreading, otherwise it will melt into an unappealing puddle
03 -
  • Keep your heat medium-low and stir frequently once the onions start browning, or they will burn quickly
  • Use the sharpest knife you have for slicing onions so they cook evenly and don't turn mushy
