Heirloom Tomato Galette with Herbs

Last Updated on August 20, 2020 by Chenée Lewis

This tomato galette is a labor of love for me! A few years ago I began a small raised-bed backyard garden. At first I only grew herbs and flowers, and then last year I tried out kale and shishito peppers, and now this year I’m trying heirloom tomatoes for the first time! Once I had enough for a small harvest, I knew that this heirloom tomato galette was exactly what I wanted to make!

This tomato galette features heirloom tomatoes of various sizes, a mascarpone filling with lemon and garlic, and a flaky, all-butter herb crust. The galette is topped with herbs straight from my garden, but you can use whatever fresh herbs you like!

Ingredients

Here’s what you’ll need to make this heirloom tomato galette. First, for the herbed galette crust:

• all-purpose flour – the structure of our dough.
• Italian herb seasoning – this adds so much flavor to your galette crust and complements the flavors in the filling so well!
• cold salted butter – it’s important that your butter is very cold so that it stays intact while you’re making your dough.
• ice cold water – cold water helps keep the butter cold, which ensures a flaky crust. I like to just stir the water with a few ice cubes before measuring.

Then, for your galette filling you’ll need:

• mascarpone – Mascarpone is a smooth, Italian cream cheese. It should be softened to room temperature. If you have a hard time finding mascarpone, regular cream cheese should also work.
• fresh garlic – Minced or pressed through a garlic press.
• lemon zest – so crucial to brighten up the mascarpone filling and complement the fresh tomatoes.
• a beaten egg – helps to give the filling a little structure.
• salt & pepper
• heirloom tomatoes – I used Black Krim and Yellow Pear varieties. You can also use regular tomatoes, just try to find the most flavorful and ripe ones that you can!

And finally, to top your galette and get it ready for baking, you’ll need:

• fresh chopped herbs – you can use whatever herbs you like or have on hand — I gathered some from my garden, so I used thyme, sage, chives, basil, and Italian oregano.
• egg wash – this is an egg beaten with a tablespoon of water. It coats the outer edge of the crust, helping it brown and making it more shiny and flaky!
• salt and pepper – a final flourish of flavor before baking (sorry for the alliteration, haha!)

Recommended Tools

I love this heirloom tomato galette recipe, in part because it’s so easy to make with simple kitchen tools. First, to make the galette crust you’ll need either a food processor, a stand mixer, a pastry cutter, or just your hands. Then you’ll just need a rolling pin and a sheet pan, and you’re ready to bake!

Tips to make the best tomato galette

Chill your dough before assembling the galette. This step allows the butter in the crust dough to re-solidify and gives the crust that flaky texture that is so amazing! I like to chill the dough for at least a couple hours. If you are able, you can even plan ahead and make your dough the night before, or see below for more make-ahead tips!

Chill your galette AFTER assembling, too! This is one more step to help ensure the flakiest crust, and keep the galette from spreading too much as it bakes. I simply place the galette, sheet pan and all, into the freezer while the oven preheats.

Make ahead and save time! This is related to that first tip above — I would definitely recommend making your galette crust a day or so early and just pop it in the fridge for up to two days. If you’re really looking to maximize your time, you can freeze the crust for up to two months before baking — just be sure to thaw it in the refrigerator 24 hours before rolling it out. You can also make the mascarpone filling up to one day ahead of time, too — just let it sit out for about 10 minutes to soften before spreading onto your galette crust.

Instructions

Prepare herb galette crust

• Combine flour and herbs in a bowl, food processor, or in the bowl of a stand mixer.
• Cut in butter until mixture resembles coarse crumbs.
• Slowly add water and mix just until dough comes together.

• Spread filling in a circle onto galette crust, leaving 1-2 inches from the outer edge open.
• Place tomatoes on top of mascarpone filling, filling in gaps as necessary. Fold and pleat remaining crust over tomatoes, leaving most of tomato filling exposed.
• Sprinkle chopped herbs onto tomatoes and sprinkle with sea salt and fresh cracked pepper.
• Brush egg beaten with water onto the outer edge of the crust. Place galette and parchment onto a large baking sheet.

Galette crust: This recipe is based on my Easy All-Butter Pie Crust recipe, but it’s even easier — because a galette is much more forgiving than a pie, we’re using just cold water instead of water and vodka.
