Heat olive oil in large skillet over high heat. Add cherry tomatoes in single layer. Blister 2–3 minutes without stirring until skins char and tomatoes begin to burst.
Add sliced garlic and red pepper flakes. Toss gently and cook 60 seconds. Press tomatoes lightly to release juice.
Add white wine, deglaze pan, cook 60–90 seconds until reduced by half. Season with salt and pepper.
Add pasta water, toss with cooked pasta in the pan. Remove from heat, tear in basil, finish with parmesan. Serve immediately.
Notes
- Use high heat — blistering only happens at high temperature, not medium. - Add fresh basil off the heat only — early basil loses all fragrance. - Mixed color cherry tomatoes give more complex sweetness and stunning visual.
