How to sauté peppers and onions: some tips

Sautéing is one of the fastest methods to cook vegetables! This method for cooking browns the outside of the food, helping complex flavors to develop (called the Maillard reaction, if you want to get technical!). The word saute means “jump” in French, meaning you need to keep the food moving by stirring or flipping the pan. Here’s what to know about how to saute peppers and onions:

  • Thinly slice the veggies. The thinner the slices, the faster it will cook.
  • Add the fat. You can use olive oil or butter for sautéing. Butter has a richer, more savory flavor.
  • Cook on medium high heat and stir occasionally. Watch that the heat is not too high.
  • Cook until crisp tender, or very tender: you choose! You’ll need about 10 to 12 minutes for crisp tender, and about 15 for very tender. The texture depends on your personal preferences and how you plan to serve your peppers.
