Warm the olive oil in a wide skillet over medium heat. Add onion and a pinch of salt. Sauté until translucent, about 4–5 minutes.
Add garlic; cook for 30 seconds until fragrant. Don’t let it brown; we’re going for suave, not roasted garlic risk.
Stir in crushed tomatoes, sugar (if using), oregano, basil, thyme, bay leaf, and red pepper flakes. Bring to a gentle simmer.
Reduce heat to low and simmer 15–20 minutes, stirring occasionally. Let the flavors mingle like two friends at a café.
Taste and season with salt and pepper. If it tastes sharp, a pinch more sugar or a splash of water can mellow it out.
Discard bay leaf. If you like ultra-smooth sauce, give it a quick buzz with an immersion blender for a few seconds.
