Ingredients
To create these mouthwatering Caramelized Peppers & Onions, you’ll need:
- 2 tablespoons extra virgin olive oil to lend a rich flavor and facilitate cooking.
- 1 large yellow onion, peeled and sliced into ¼-inch (6-mm) strips, providing sweetness and aroma that will fill your kitchen.
- 4 bell peppers, stemmed, seeded, and cut into ¼-inch (6-mm) strips, contributing vibrant colors and a crispy texture.
- ½ teaspoon salt, enhancing the natural flavors.
- ½ teaspoon freshly ground black pepper, adding a hint of warmth.
- 2 teaspoons balsamic vinegar for a touch of tangy sweetness.
- 1 teaspoon fresh thyme, finely chopped (or ½ teaspoon dried thyme), offering a fresh, earthy note to the dish.
These fresh ingredients come together to create a visually striking and aromatic dish that is hard to resist.
Step-by-Step Directions
Step 1: Preheat Your Skillet
Begin by heating the extra virgin olive oil in a large skillet over medium-high heat. This oil will serve as the foundation for your flavorful mixture.
Step 2: Adding the Veggies
Once the oil is shimmering, add the sliced onions and bell peppers, along with the salt and pepper. Give everything a good stir to ensure that the oil evenly coats the vegetables.
Step 3: Caramelizing
Now, reduce the heat to medium-low. This slower cooking process is where the magic happens! Stir the mixture frequently for about 15 to 20 minutes. As the onions and peppers cook, the natural sugars will caramelize, transforming them into delectably sweet and tender pieces. If you notice a brown coating forming on the bottom of the pan, don’t hesitate to add a few tablespoons of water and scrape it up, repeating as needed to prevent sticking.
Step 4: Adding the Final Touches
Once the vegetables are beautifully caramelized and tender, it’s time to add the balsamic vinegar and thyme. Turn the heat down to low and allow them to cook for a few more minutes. Taste and adjust the seasoning if necessary.
Step 5: Serve
Your Caramelized Peppers & Onions are now ready to be served hot or at room temperature. Enjoy the delightful aromas and flavors that are sure to make your meal memorable.
Tips & Tricks
- For deeper flavors, consider adding a sprinkle of sugar while caramelizing. This will enhance the sweetness of the vegetables.
