Avocado & Mozarella Cheese Stuffed Tomatoes

Avocado and mozzarella stuffed tomatoes is summer on a plate, the kind of fresh-from-the-farmstand appetizer that takes 5 minutes to assemble and looks like it took an hour. Vine-ripe tomatoes get hollowed into edible cups, then filled with avocado and fresh mozzarella cubes tossed in a punchy basil-balsamic vinaigrette.

The dressing comes together in a blender. Whirling fresh basil, garlic, balsamic vinegar, olive oil, and a splash of white wine produces a dressing that’s almost pesto-thin and clings to the cubes beautifully. Whisking the dressing by hand produces something thinner and less green; the blender is the right move.

Five cloves of garlic in the dressing sounds aggressive, but blended with raw garlic mellowing in the acid bath of vinegar and citrus juices, it lands sharp but not raw. The garlic note becomes the backbone the basil rides on.

Using fresh mozzarella (not pre-shredded) is non-negotiable. Pre-shredded mozzarella is coated with anti-caking starch that won’t soak up the dressing. Soft, milky fresh mozzarella drinks the vinaigrette in like a sponge and turns into the best part of every bite.

Pro Tips

• Save the scooped-out tomato pulp for tomato-basil pasta sauce or gazpacho. It’s already seasoned by the surrounding tomato.
• Salt the inside of the hollowed tomatoes lightly and let them drain upside-down on paper towels for 5 minutes before stuffing. This prevents watery filling.
• Cut the avocado at the very last minute. Even with the dressing, exposed avocado oxidizes within 15 minutes.
• Use the highest-quality balsamic you can afford. Real aged balsamic has natural sweetness; cheap stuff tastes vinegary.
• Serve immediately or hold for under 30 minutes. The dressing softens the mozzarella and the tomato cups release juice past that window.

Variations

• Add 2 tablespoons toasted pine nuts to the filling for a textural crunch.
• Top each stuffed tomato with a few thin ribbons of prosciutto for a richer, salty meat element.
• Use multicolored heirloom tomatoes for a striking visual presentation.
