Italian Roasted Peppers in Olive Oil

Italian roasted peppers in olive oil are the antipasto-platter staple that Italian nonnas have been jarring for generations. Three colors of bell peppers (red, yellow, and green) roast in a hot oven until their skins blister and pull away, then get peeled and packed in jars with extra-virgin olive oil and a splash of white wine vinegar.

The roasting is the most important step. A blistering-hot oven char the skins, sweetens the flesh through caramelization, and creates that signature deep, smoky-sweet flavor that no raw pepper can match. Let the roasted peppers cool fully before peeling. The steam trapped under the charred skins loosens them from the flesh, so they slip right off with light fingers.

The jar arrangement is part of the appeal. Alternate colored layers (green on the bottom, red in the middle, yellow on top) for a striped-jar look that turns this into an edible gift. Pour the olive oil and vinegar mixture in first, layer in the peppers, then top with more oil to cover completely. The oil acts as a seal and preservative. Refrigerated and submerged, these keep for two weeks. Serve on bruschetta, with cured meats and cheeses, or piled onto an Italian sub.

Kitchen Tips

• Roast peppers whole on a sheet pan, not cut. Whole peppers blister evenly and the skins pull off in larger pieces.
• Cool the roasted peppers in a covered bowl for 15 minutes. Trapped steam makes peeling easier.
• Do not rinse the peeled peppers under water. Water dilutes the flavor and shortens jar life. Pat with a damp paper towel if needed.
• Top the jar with enough oil to fully cover the peppers. Any exposed pepper to air can mold within days.

Variations

• Add 2 cloves of garlic and a few sprigs of fresh basil or oregano to the jar for a more aromatic infusion.
• Stir a teaspoon of capers or chopped olives into the oil for a Mediterranean tapenade flavor.
• Use balsamic vinegar instead of white wine for a sweeter, deeper preservation flavor.
