Garlic buttered mushrooms are one of the best inventions by man, and pairing them with classic caprese flavors is simply genius. I love the large portobello mushroom caps because you can basically stuff them with almost anything and the result is a beautiful meal that you created in no time–in this case a melty caprese salad inside of a portobello mushroom cap!

Caprese, the classic mix of tomatoes, sweet basil and fresh mozzarella, is one of my favorite flavor combinations. Whether it’s a fresh caprese salad with beefsteak tomato slices layered with fresh buffalo mozzarella, a delicious wood-fired Margherita pizza, or our Delightful Caprese Chicken, this flavor combo can’t be beat!

Pro Tip: If you cannot find a prepared balsamic glaze, make your own by combining 1 cup balsamic vinegar with 1/4 cup brown sugar and simmering until reduced by half.
