There is something truly magical about a simple, slow-simmered marinara sauce. It’s the backbone of so many of my favorite Italian meals, from a basic bowl of spaghetti to a fancy eggplant parmesan. The secret lies in using high-quality ingredients—specifically those sweet San Marzano tomatoes and a generous glug of good olive oil—to create a sauce that tastes like it spent all day on the stove, even though it takes less than thirty minutes.

What I love most about this recipe is its versatility. You can keep it chunky for a rustic feel or blend it smooth if you're serving picky eaters. The fragrance of fresh basil and toasted garlic hitting the pan is enough to bring anyone into the kitchen. Once you’ve tasted the difference between this and the jarred stuff, there’s simply no going back!

Ingredients

  • San Marzano whole peeled tomatoes:28 oz
  • Extra virgin olive oil:1/4 cup
  • Garlic cloves, thinly sliced:4 pieces
  • Dried oregano:1/2 tsp
  • Red pepper flakes:1/4 tsp
  • Fresh basil leaves, torn:1/2 cup
  • Kosher salt:1/2 tsp

Instructions

  1. Pour the canned tomatoes into a large bowl and crush them by hand or with a fork until they reach your desired consistency.

Tips & Notes

  • For a smoother sauce, use an immersion blender directly in the pot before adding the fresh basil.
  • If the tomatoes are a bit acidic, add a tiny pinch of granulated sugar to balance the flavors.
  • This sauce freezes beautifully! Store it in airtight containers for up to 3 months.
