Dice ripe roma tomatoes roughly into ½ inch pieces. Set aside.
Heat olive oil in large skillet over medium heat. Add minced garlic and red pepper flakes. Cook 60–90 seconds until fragrant and just golden.
Add diced tomatoes, salt, and pepper. Increase to medium-high heat. Cook 10–12 minutes stirring occasionally until tomatoes break down and sauce thickens. Taste and add sugar if needed.
Add pasta water, toss with cooked pasta in the pan. Remove from heat, tear in fresh basil, drizzle cold olive oil, finish with parmesan. Serve immediately.
Notes
- Use ripe peak-season tomatoes only — flavor is everything in this sauce. - Add fresh basil at the very end or off heat — never during cooking. - Finish with cold olive oil drizzle for a bright, fresh restaurant-quality note.
