Ingredients

  • 3 tablespoons oil , use vegetable oil for Mexican and olive oil for Italian
  • 3 large large bell peppers sliced thinly (use green and red for Mexican and red, yellow, and orange for Italian)
  • 2 medium red onions sliced thinly
  • ¾ teaspoon salt

Mexican

  • 1 ½ teaspoons dried oregano

Italian variation

  • 2 tablespoons dry white wine
  • ½ teaspoon rosemary
  • ¼ teaspoon red pepper flakes

Instructions

  • Peppers and onions: Heat a large skillet with oil to medium high heat. Add peppers and onion and cook, stirring on occasion, until they begin to soften (about 5-7 minutes).
    3 tablespoons oil, 3 large large bell peppers, 2 medium red onions
  • Spices and flavorings: Depending on the variation you choose, add the wine, salt, and spices. Cook for 5-10 minutes more or until the peppers and onion are as soft as desired. Typically Mexican style peppers and onions are a bit firmer, and Italian style are a bit softer. Season with additional salt and pepper to taste.
    ¾ teaspoon salt

Notes

See the blog post for ingredient notes, substitutions, step-by-step photos, expert tips and FAQs.
Use medium-high heat to cook peppers so they caramelize correctly. Cooking over low heat will steam them instead of sautéing them.
Storage: Store leftover sautéed peppers and onions in an airtight container in the refrigerator for up to 3 days. 
The Italian variation tastes great with pasta and our Dairy-Free Shrimp Scampi recipe. The Mexican variation is perfect with Chipotle Cilantro Lime Rice.
