This caramelized onions and Swiss chard recipe is made with 4 simple ingredients and can easily be made vegan. Use rainbow or red chard for this delicious family-favorite side dish! Enjoy paired with my Almond Crusted Baked Chicken.


  • 2 medium/large onions
  • 1 lb Swiss chard (any variety)
  • 24 Tbsp cooking fat (I prefer bacon grease)
  • ½ – 1 tsp granulated garlic
  • 12 tsp salt
  • ½ -1 tsp pepper


  1. Preheat your skillet on low and add your cooking fat.
  2. Meanwhile, cut your onions in half and thinly slice all halves. When all the onions are sliced, add to the pan.
  3. Stir every few minutes, for the first 5-7 minutes or so, to ensure the onions are thoroughly coated with fat, are not sticking to the pan, and are cooking.  Adjust the heat, if necessary, but keep the temp low. To truly carmelize the onions, you need to cook them low and slow.
  4. Meanwhile, thoroughly wash the chard and dry completely. Then thinly slice the chard.
  5. When the onions begin to brown slightly and turn translucent, add the chard. Cook, stirring every few minutes, until the chard wilts and the onions turn brown and caramelize.
  6. Season to taste with granulated garlic, salt, and pepper. Serve warm.


  • One good thing about the slow cooking temperature, is that you don’t have to hover over the stove the entire time. I like to be close by for the first 5 minutes or so, to make sure the onions don’t get stuck to my cast iron skillet, and to make sure that all the onions are covered well in my cooking fat (my favorite is re-using bacon grease!).
  • Once all the onions are coated in fat, and I’m sure nothing is sticking, I move on to whatever else I’m cooking that night and come back to stir occasionally.
