Two 28-ounce cans whole peeled tomatoes, crushed by hand
1 tablespoon red wine vinegar
2 thyme sprigs
½ teaspoon dried oregano
Kosher salt and freshly ground black pepper, to taste
Directions
In a 4-quart Dutch oven, heat the pancetta and olive oil over medium-high heat. Cook until the pancetta is golden and the fat has rendered, 8 to 10 minutes. Add the garlic and pepper flakes, and cook until fragrant, 2 minutes. Deglaze the pan with the maple syrup and cook until slightly reduced, 1 to 2 minutes.
Add the remaining ingredients, bring to a simmer, then cook, stirring occasionally, until thickened, 40 to 45 minutes. Use immediately or store in the refrigerator for up to 1 week.
