The first part of this recipe explains how to easily caramelize onions. Make sure your onions are fresh and firm, and if possible get onions from Minkus Family Farms!! The second part of the recipe is for vegan cornbread with caramelized onion topping. I make this mild flavored and grainy cornbread often, and the caramelized onions are a great touch.
Serves: makes 1 cup onions
Caramelized Onions
  • 2 lbs yellow and/or red onions
  • ½ tsp sea salt or kosher salt
  • 2 tbsp oil
Vegan Cornbread
  • 1¾ cup cornmeal (any color, fine ground)
  • ½ cup flour
  • 1½ tsp baking powder
  • ½ tsp baking soda
  • 2 tsp salt
  • 2 tbsp sugar
  • 2 tbsp flax meal
  • 6 tbsp water
  • 1½ cup soy milk (or other non-dairy milk like almond or cashew)
  • 1 tsp apple cider vinegar or white vinegar
  • ¼ cup oil (I used grapeseed)
  • ½-1 cup caramelized onions
Caramelized Onions
  1. In a large cast iron skillet warm oil on medium high heat.
  2. Add the sliced onions, and stir, break apart, and create an even layer.
  3. Add salt, and stir some more.
  4. Reduce heat to medium, and cook until onions begin to turn translucent.
  5. Stir once again, then turn heat to medium-low. Cook for about 5 minutes, then reduce the heat to low (though not the lowest).
  6. Cook for 30 minutes, stirring occasionally. Be careful that the onions don't stick or burn.
  7. In this time the onions should soften, turn brown, and sweeten. They should not burn at all.
  8. Cook on low heat until your desired texture and flavor is reached.
  9. Add 1 tbsp of sugar for sweeter caramelized onions or 1 tbsp of vinegar (any kind) for tangy onions and to deglaze the skillet.
  1. Combine dry ingredients in a medium mixing bowl and stir to combine.
  2. Combine flax seed meal and water in another mixing bowl, and let it sit for at least 5 minutes until the mixture has thickened.
  3. Add the remaining wet ingredients, and whisk to combine.
  4. Pour wet into dry, and stir well to combine––careful not to overmix.
  5. Pour into a 9x9 or 8x8 baking dish and top with caramelized onions.
  6. Bake for 20-25 minutes or until golden and a toothpick comes out clean or with crumbs.
