So long Summer means you may have seasonal produce lingering on your countertops. Like a fine vino, tomatoes can get better with age, but the wrinkly skin texture may be off-putting and have you questioning if you should pitch em’…DON’T! In Italian cuisine, tomatoes are “the golden fruit” and there is always a way to #zerowaste these beauties. A simple, quick slow roast will salvage your surplus and render a delicious way to incorporate them into a whole bunch of delicious foods – pastas, pizzas, sides, including these Open-Faced Roasted Tomato Caprese Panini (or crostini if using smaller slices of bread). One sheet pan batch of these roasted tomatoes will yield tons of options to devour them – let’s roast!
Roasted Tomato Caprese Ingredients
Tomatoes: use whatever tomatoes are beginning to wrinkle. Seriously, there’s no wrong tomato for this recipe. I used a small carton of grape tomatoes for this batch, but cherry & heirloom are verified delish too.
Note about properly storing tomatoes: I love cooking, but I am not a food storage expert. In fact, it was just in 2020 when we started being a lot more mindful of how we store produce I learned tomatoes should be stored at room temp, not in the fridge. I should have known this – Dad had a veggie garden and always kept his freshly picked tomato harvest in a wicker basket by the stove. We live, we learn. Check out this Produce Shelf Life Guide for more storage tips.

Sheet pan roast your wrinkly tomatoes for a delicious zero waste food solution!
Basil: fresh is best. Full stop.
Fresh Mozzarella: I usually have a large ball of fresh mozzarella (aka Buffalo Mozzarella – the difference is water buffalo vs. cow’s milk) in my fridge at all times, and sliced one up for this recipe. I also really love the pre-sliced bocconcini medallions for caprese salads and appetizers.
Extra Virgin Olive Oil: any will do. If I’m being honest, we usually stock the one on sale.
Balsamic Reduction: the best, most authentic glaze will say “Made in Modena” on the front of the bottle. Another item I always have stocked year-round.

The main difference between crostini & panini is really just the size of the bread slice!
Crostini/Panini – What’s the Difference:
Panino (“Panini” plural) is simply a sandwich made with Italian Bread. Crostini (“Crostini” singular)are simply an Italian appetizer made with smaller slices of grilled or toasted bread & usually topped with cheeses, meats or veg, or brushed with herbs + oil & delicious on their own. So the difference between Crostini & Panini is really just the slice of your bread base.to save time, we often use premade, store-bought crostini, but also love using up near-stale bread and making our homemade crostini/panini recipe. For this food-torial, however, I cheated and used pre-sliced Calabrese bread, making this more of an open-faced Caprese panino then a crostini. Ciabatta and any baguette are lovely for this recipe too.
How to Store Your Leftover Sheet Pan Roasted Tomatoes
Your roasted sheet pan tomatoes are best used in a few days time, but will last about 3-5 days stored in a sealed jar and by adding a bit more olive oil over top.
