Caramelized Red Onion Tart
When I was thinking about how to incorporate red onions into my 1000th Post Party menu, I decided to search foodgawker. When I saw this Caramelized Red Onion Tart, I was instantly drawn in by how pretty it was. As I read the recipe, I became more intrigued by how delicious it sounded!
Caramelized onions make everything taste better. And this tart is basically caramelized onions mixed with fresh thyme piled on top of a flaky buttery pie crust. What is better than that?!? This recipe was the surprise hit of the night. Multiple people said it was their favorite thing. And it was definitely my favorite savory treat. I will definitely be making this again!

Caramelized Red Onion Tart
Caramelized red onions make this savory tart beautiful and delicious!
Yield: Serves 8
Ingredients:
For the Pie Crust
2 1/2 cups all-purpose flour
1/4 teaspoon salt
1 tablespoon sugar
1 cup (2 sticks) unsalted butter, chilled and cut into small pieces
1/4 to 1/2 cup ice water
For the Tart
4 Tbsp butter
6 tsp sugar
1 pound red onions, cut in wedges
3 Tbsp red wine vinegar
2 Tbsp fresh thyme leaves
Salt
Pepper
Directions:
For the Pie Crust
In the bowl of a food processor, combine flour and salt; pulse to combine. Add butter, and pulse until mixture resembles coarse crumbs with some larger pieces remaining, about 10 seconds. (To mix by hand, combine dry ingredients in a large mixing bowl, then cut in butter with a pastry blender.)
With machine running, add ice water through feed tube in a slow, steady stream, just until dough holds together without being wet or sticky. Do not process more than 30 seconds. Test by squeezing a small amount of dough together; if it is still too crumbly, add a bit more water, 1 tablespoon at a time.
Turn out dough onto a clean work surface. Divide in half, and place each half on a piece of plastic wrap. Shape into flattened disks. Wrap in plastic, and refrigerate at least 1 hour or overnight. The dough can be frozen for up to 1 month; thaw overnight in the refrigerator before using.
For the Tart
Put the butter and sugar in a frying pan and let them melt until well combined.
Add the red onion wedges and cook them on a slow fire for 10 to 15 minutes, stirring until caramelized. Add the vinegar and thyme, salt and pepper and let the onions cook till the liquid is fully absorbed.
Roll out your pie crust in a round shape and keep it aside.
Preheat oven to 350 F.
Cover the base of the springform pan with baking paper and put onions on it.
Cover them with the pie crust circle and tuck the pastry well on the sides.
Bake for 20-25 minutes (or until golden).
When ready take it out of the oven and let it rest for 10 minutes so that the juices dry and caramelize. Then flip over and serve.

I am Jen the Beantown Baker. Engineer by day and baking maven by night. Hubby serves as my #1 fan and official taste tester. We got hitched back in 2006. Barefoot. In the sand. With the waves crashing behind us. It was one of the best decisions we’ve ever made. 
I’m with you–every ingredient in this salad is a winner on it’s own. Together? Forgetaboutit! The colors are beautiful and I can imagine how great it tastes with the balance of bitter, sweet, and tart.
Love the new layout, also. Way to go!
Yum! I am also addicted to kale since doing a CSA here in Boston 🙂
It’s so funny, because as I was scrolling through Tastespotting tonight and saw this post, I had to click because it looked so familiar to my winter couscous bowl… and then, I couldn’t believe it when I saw my blog credited at the bottom! This is a first for me 🙂 Thanks so much for the credit!
So you’ve recently moved back to Cincinnati? Which part? My family and I live in Anderson Township.

Thanks so much for the recipe!!
We work in West Chester and are living in Oakley right now. Trying to find a house at some point…
I think this sounds amazing, Jen! And I love how colorful it is. I am always looking for new winter salads that are colorful, flavorful, and interesting.

This is definitely colorful, flavorful, and interesting. I have seriously been OBSESSED with pomegranates this winter, and this salad totally feeds into that obsession.
I’m on a major quinoa AND kale kick so this salad is right up my alley. So colorful and pretty, too!

Pretty food is definitely always tastier than ugly food 🙂
looks a lot like the one i posted last week 🙂 obviously, i’m all over it!!

Very similar indeed!
This is perfect for that kale and pomegranate I have in the fridge! I’m always excited to find new things to put together ahead of time for lunches and dinners, thanks! Hope you are settling in nicely 🙂

I couldn’t agree more. Making food ahead of time saves the day during the week! I can’t imagine not eating leftovers… Things are going pretty well for us in Ohio so far. Hope things are going well for you and your little bundle on the way!
Sounds great to me! I love the ingredients. And the colors 🙂
This sounds right up my alley! YUM!!
I was thinking about an easy and colorful, flavorful, and power-packed healthy side dish to bring for a potluck lunch after a trail work party this coming weekend. I had these amazing cute pumpkins to harvest from my garden and love both kale and quinoa. I thought to myself, mmmm, what if I made some kind of pumpkin kale quinoa and goat cheese salad to share? One quick internet search and I came across this gem! I modified and concocted a tad, which is normal for me. Thanks so much for the recipe and ingredient confirmations! The honey, olive oil, and smokey / spicy combo was the secret ingredient for me! Happy fooding!
