If you’re not sure what to do with tomatoes this summer, try my Southern version of a Tomato Galette. It’s tomato season and they are everywhere, sweet and juicy all by themselves but even better when baked into a pie or a galette. This Cheesy Tomato Galette has it all, a cheesy mayonnaise mixture, sliced tomatoes and a flaky crust, all baked in a cast iron skillet.
I got the idea to make this in a cast iron skillet when I forgot to put a fruit filled galette on a rimmed baking sheet. The juicy filling seeped out into my oven for a smoky sticky mess. Tomatoes are even juicier than peaches so I thought that baking it in a skillet would ensure that all the juices stayed in the pan and not in my oven! Not only did the cheesy tomato filling stay together, but the cast iron helped the crust turn golden brown and flaky and my smoke detector didn’t go off, always a win in my house.
While the tomatoes are the highlight of a tomato galette, the filling surrounding the tomatoes is amazing and would make my Southern mother-in-law proud.
What is in a Southern tomato pie or galette
The one ingredient, other than tomatoes, that you must have in a Southern tomato pie or galette is mayonnaise. Where did this idea come from, well I can tell you it’s because any true Southerner loves a good tomato sandwich. The only other ingredient on a tomato sandwich is mayonnaise. Ok, I just have to say, YUCK! While I’ve lived in the South since I was 5, I don’t like mayonnaise except in small doses or mixed with something else and Duke’s mayonnaise is a bit too tart for me. I’m a Hellmans’ girl. But I am certainly not putting an inch or so of mayonnaise on tomatoes and white bread. The thought of eating that makes me gag. But from that sandwich, which all other Southerners seem to love, is why you will find mayonnaise in any tomato pie you sample in the South.
For this Cheesy Tomato Galette there is mayonnaise, but it’s mixed with a bit of sour cream, cream cheese, cheddar cheese and gruyere. While the gruyere is not very Southern, it’s my favorite and creates the perfect balance of flavors in this galette.
How do you make Cheesy Tomato Galette
- Start by making a pie crust. You can use a plain pie crust or add some parmesan and black pepper to make it even better. If you’re in a pinch, of course you can grab one from the grocery.
- Slice your tomatoes, any type will work, I like to use a mixture, but any ripe tomato will be amazing. Now for a CRUCIAL step, lay out the tomatoes on a platter and salt them. This will draw out some of the juices, otherwise you will have tomato soup.
- While waiting on the tomatoes, combine your cheese mixture and roll out the pie crust and drape it over the skillet.
- Start your layers with half of the cheese mixture, then tomatoes then top with remaining cheese mixture and bake.
- The final but IMPORTANT step is that it needs to sit for about 30 minutes before eating. If you try to slice it right away, it will be one big gooey delicious mess. If you want pretty slices, be patient.
