Sweet peppers are the name of the game here, but tossing a few hot ones into the mix would be nice as well. This recipe was developed to preserve the summer bounty from your garden or farmers' market; it freezes well for up to 3 months. Try this mélange of peppers, tomatoes and onions with a plate of cheese and crackers; toss it with pasta and chopped herbs; or pile it on grilled chicken and melt some fontina on top.

6 cups


  • ½ cup thinly sliced garlic

  • ½ cup extra-virgin olive oil

  • 1 tablespoon chopped fresh herbs, such as rosemary, thyme and/or oregano

  • 1 large sweet onion, sliced

  • 4 cups chopped tomatoes

  • 3 ½ pounds bell peppers, sliced 3/4 inch thick

  • 1 teaspoon salt

  • 1 tablespoon white-wine vinegar


  1. Heat garlic, oil and herbs in a large pot over medium heat until fragrant and starting to sizzle, about 2 minutes. Add onion and cook, stirring occasionally, until softened but not browned, about 8 minutes. Add tomatoes and cook, stirring occasionally, until they are broken down, about 5 minutes. Add bell peppers and salt; bring to a simmer. Cover and cook, stirring occasionally, until the peppers are mostly submerged in the liquid they give off, about 40 minutes. Uncover and cook until the liquid is reduced by about half and the peppers are very tender, about 30 minutes. Stir in vinegar. Serve warm or at room temperature. Let cool completely before refrigerating for up to 1 week or freezing for up to 3 months.


To make ahead: Refrigerate for up to 1 week or freeze for up to 3 months.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
