Ingredients

Scale

Vegetables

  • 3 large sweet bell peppers (red, orange, and/or yellow), stemmed, cored, seeded, and sliced lengthwise into thin strips
  • 1 medium onion, thinly sliced
  • 3 cloves garlic, minced
  • 8 ounces cremini mushrooms, sliced

Other Ingredients

  • 3 tablespoons olive oil
  • Salt and freshly ground black pepper, to taste
  • 1 1/2 tablespoons balsamic vinegar
  • 2 tablespoons chopped fresh parsley

Instructions

  1. Prepare the peppers: Remove the stems, cores, and seeds from the bell peppers and slice them lengthwise into thin strips. Set aside for later use.
  2. Sauté the onions: Heat olive oil in a large pan over medium heat. Add the thinly sliced onions and cook, stirring frequently, until they become very soft and develop a golden color, about 7 to 8 minutes. Add the minced garlic and sauté for an additional minute to release its flavor.
  3. Cook the mushrooms: Add the sliced cremini mushrooms to the pan. Season with salt and black pepper. Continue cooking, stirring occasionally, until the mushrooms release moisture and it evaporates, and they turn a rich golden brown, approximately 6 to 8 minutes.
  4. Add and soften the peppers: Add the prepared bell pepper strips to the pan. Season again with salt and pepper. Stir frequently and cook until the peppers soften, about 6 minutes.
  5. Incorporate balsamic vinegar and simmer: Pour in the balsamic vinegar, stir, then cover the pan. Cook for an additional 6 to 8 minutes, stirring every minute or so to prevent sticking and promote even cooking.
  6. Final reduction: Remove the cover and continue cooking for 2 to 3 more minutes, stirring often. The peppers should be very tender and sweet. Taste and adjust seasoning if necessary.
  7. Serve: Transfer the sautéed vegetable mixture to a large bowl, sprinkle with chopped fresh parsley, and serve family-style as a side dish or topping.

Notes

  • Use a variety of colored bell peppers for a visually appealing dish.
  • If you prefer a milder garlic flavor, reduce the cloves to 1 or 2.
  • This dish pairs well with grilled meats, pasta, or as a topping for toasted bread.
  • For a vegan option, ensure balsamic vinegar does not contain added honey or animal products.
  • Leftovers keep well in an airtight container in the fridge for up to 3 days.
