In a medium bowl, mix together the extra virgin olive oil, red wine vinegar, finely chopped red onion, chopped basil, chopped parsley, salt, and pepper. Add the halved baby plum tomatoes to the bowl and toss until evenly coated. Let the tomatoes marinate at room temperature for 15–30 minutes.
Slice the ciabatta and toast on a grill pan over medium heat for 2–3 minutes per side, until golden and crispy.
Place the marinated tomatoes on a serving platter and arrange them around the burrata.
Garnish with extra basil and serve immediately with toasted ciabatta.
Notes
Let the Tomatoes Sit: I like to let the tomatoes marinate for the full 30 minutes so they really soak up the dressing and taste their best.Chop the Onion Finely: I always chop the red onion as small as I can; it blends better into the marinade and doesn’t overpower the tomatoes.Toast the Bread Just Before Serving: I toast the ciabatta right at the end so it’s still warm and crisp when I bring the plate to the table.Serve the Burrata at Room Temp: I take the burrata out of the fridge early; once it softens a bit, it becomes extra creamy and spreads beautifully.Spoon the Marinade Over Everything: I like to drizzle some of that herby tomato marinade over the burrata and bread; it’s too good to waste!
