🥗 Ingredients

The Vegetables

  • 3 large Red Bell Peppers (seeded and cut into 1/2-inch wide strips)
  • 2 large Yellow Bell Peppers (seeded and cut into 1/2-inch wide strips)
  • 2 medium Red Onion (halved and thinly sliced into half-moons)
  • 4 Garlic Cloves (thinly sliced)
  • 1.5 cups Cherry Tomatoes (halved, or use high-quality canned crushed tomatoes)

The Aromatics and Pantry

  • 4 tablespoons Extra Virgin Olive Oil (high quality cold-pressed)
  • 2 tablespoons Red Wine Vinegar (to brighten the flavors)
  • 1 teaspoon Granulated Sugar (to balance the acidity)
  • 1 teaspoon Sea Salt (plus more to taste)
  • 1/2 teaspoon Black Pepper (freshly cracked)
  • 1 teaspoon Dried Oregano (preferably Sicilian on the branch)
  • 1 pinch Red Chili Flakes (optional, for a subtle heat)

Finishing Touches

  • 1/2 cup Fresh Basil Leaves (hand-torn)
  • 1 tablespoon Capers (rinsed and drained (optional))

👨‍🍳 Instructions

  1. 1

    Prepare your vegetables by washing the peppers, removing the seeds and internal white ribs, and slicing them into uniform strips about 1/2 inch wide. Slice the onions and garlic as directed.

  2. 2

    In a large, heavy-bottomed skillet or Dutch oven, heat 3 tablespoons of the extra virgin olive oil over medium heat until shimmering.

  3. 3

    Add the sliced red onions to the pan with a pinch of salt. Sauté for 8-10 minutes, stirring occasionally, until they are soft, translucent, and just beginning to turn golden.

  4. 4

    Stir in the sliced garlic and red chili flakes (if using). Cook for just 1-2 minutes until the garlic is fragrant, being careful not to let it brown or turn bitter.

  5. 5

    Add all of the sliced bell peppers to the pan. Increase the heat slightly and toss well to coat the peppers in the flavored oil and onions.

  6. 6

    Cook the peppers for 10 minutes, stirring frequently. They should begin to soften and take on a little bit of color on the edges.

  7. 7

    Stir in the halved cherry tomatoes (or crushed tomatoes), sugar, dried oregano, sea salt, and black pepper. The tomatoes will release their juices, creating a light sauce.

  8. 8

    Reduce the heat to low, cover the pan with a tight-fitting lid, and let the mixture simmer gently for 20-25 minutes. This slow cook is essential for the 'silky' texture.

  9. 9

    Remove the lid. If the mixture looks too watery, increase the heat to medium-low and cook uncovered for another 5 minutes to thicken the sauce. If it looks too dry, add a splash of water.

  10. 10

    Stir in the red wine vinegar and capers (if using). Let it cook for another 2 minutes to allow the vinegar's sharpness to mellow and integrate into the vegetables.

  11. 11

    Turn off the heat. Drizzle with the remaining tablespoon of olive oil and stir in half of the torn basil leaves.

  12. 12

    Taste and adjust the seasoning with more salt or vinegar if needed. Let the dish rest for at least 10 minutes before serving—this allows the flavors to truly marry.

  13. 13

    Transfer to a serving platter and garnish with the remaining fresh basil leaves.

💡 Chef's Tips

For the best texture, don't rush the onion-softening stage; low and slow prevents burning and maximizes sweetness. Use a mix of red, yellow, and orange peppers; avoid green peppers as they are more bitter and lack the necessary sugar for this dish. If you have time, make this a day in advance; the flavors deepen significantly after a night in the refrigerator. Always finish with a drizzle of your best quality olive oil right before serving to add a fresh, grassy note. For a smoky variation, you can char the peppers over a gas flame and peel them before stewing, though the traditional method is raw-to-pan.

🍽️ Serving Suggestions

Serve at room temperature atop toasted ciabatta rubbed with a garlic clove for an incredible bruschetta. Use it as a vibrant side dish for grilled swordfish, roasted chicken, or Italian sausages. Stir leftovers into a frittata or serve alongside soft scrambled eggs for a gourmet breakfast. Pair with a crisp, chilled Vermentino or a light-bodied Sangiovese to complement the acidity. Top with a ball of fresh Burrata cheese; the creamy center acts as a perfect foil to the sweet and tangy peppers.
