In a medium saucepan, heat a generous drizzle of olive oil over medium heat.
Add the minced garlic and, if using, the whole dried chili pepper.
Cook for about 1 minute, just until the garlic is fragrant — don’t let it brown.
If you're using, add a teaspoon of tomato paste and stir it well.
Pour in the crushed tomatoes and stir well to combine with the garlic and oil.
Add about one glass of water (use the tomato can to measure — swirl to get every bit of tomato out) and stir again.
Season the sauce with salt, black pepper, and sugar. Drop in the bay leaf and sprinkle in the oregano.
Add the red wine and bring everything to a gentle simmer.
Let the sauce cook uncovered for at least 25 minutes, stirring occasionally, until it has thickened and the flavors have come together.
Taste and adjust seasoning as needed. Don’t forget to remove the bay leaf before serving.
