How To Make Caramelized Peppers & Onions

Caramelized Peppers & Onions Recipe Tips

  • Cook on Low Heat: Be patient! Caramelizing requires cooking on low to medium heat to allow the sugars to slowly break down, giving the peppers and onions a deep, rich flavor.
  • Stir Occasionally: Stir the peppers and onions occasionally to prevent burning, ensuring even caramelization.
  • Use a Cast Iron Skillet: For even heat distribution and the best results, use a cast iron skillet or heavy-bottomed pan.
  • Add a Splash of Balsamic Vinegar: For extra flavor depth, add a splash of balsamic vinegar at the end of cooking.
  • Customize the Veggies: Feel free to add other veggies, like mushrooms or zucchini, for a more complex flavor profile.
  • Salt to Taste: Adjust salt as you go to ensure the flavors are balanced.
  • Don’t Rush: Patience is key! Low and slow cooking brings out the best in these veggies, so take your time to achieve perfect caramelization.

Storing

  • Storing: Store caramelized peppers and onions in an airtight container in the refrigerator for up to 3-4 days. Let them cool completely before sealing to prevent condensation inside the container.
  • Freezing: For longer storage, freeze caramelized peppers and onions in a freezer-safe bag or container for up to 2-3 months. Make sure to cool them before freezing and try to remove as much air as possible.
  • Reheating: Reheat caramelized peppers and onions in a skillet over medium heat until warmed through. Alternatively, you can microwave them in short intervals, stirring in between to ensure even reheating.
