Heat your olive oil and butter until shimmering before adding cherry tomatoes, then let them sit undisturbed for 2-3 minutes per side to develop a caramelized exterior that concentrates their sweetness.

Save at least 1 cup of starchy pasta water before draining—this liquid is essential for emulsifying the olive oil and creating a silky sauce that clings to each strand of pasta.

Toss cubed mozzarella into the pasta after removing from heat so it softens gently without becoming stringy or broken—preserving those creamy, intact pieces throughout the dish.

Split your fresh basil: add half during tossing for integrated flavor, and reserve half for a final garnish to maintain bright, peppery aromatics and vibrant color.

Cook pasta 1-2 minutes under the package recommendation, as it will continue cooking slightly when combined with the warm tomato mixture—ensuring it stays perfectly firm and doesn't turn mushy.
