Gluten-Free Salted Caramel Apple Tart

I’m not sure what came over me last weekend, but the idea of a salted caramel apple tart just worked its way into my imagination and wouldn’t let go. It was entirely too specific to be denied — an apple tart would’ve been fine, even an apple crisp, but this HAD to have salted caramel, and had to be gluten-free. So I got to work.

While this tart is easy enough for even novice bakers to make, it has a few parts to it which add up in terms of actual cooking plus resting time. If you’d rather not do it in one pass, you could easily start a day or two early by prepping the crust and the caramel and refrigerating them until you’re ready to proceed.

Gluten-Free Tart Crust

I wanted to use almond flour for the crust because I thought the flavor would complement the apples and caramel nicely, so I searched for a recipe that guaranteed something more flaky than dense and chewy, which can sometimes be a problem with almond flour. Turns out that meant adding some tapioca starch, but not enough to overwhelm the nutty flavor of the almonds. The recipe I chose from Cassidy’s Craveable Creations worked out great. There’s no need to parbake — just follow her instructions to prep and rest the dough, then go from there. (You’ll need to purchase finely ground almond flour rather than almond meal for this, which isn’t always easy to find locally. Bob’s Red Mill is delicious, but too coarse for a lot of the recipes I make, so I order flour online in five pound bags and store it in the freezer for maximum freshness. I’ve put together a shopping guide at the end of this post so you can find any specialty items I mention.)

Salted Caramel

Salted caramel is a snap to make, and it’s a great way to use any leftover heavy cream you may have hanging around. The nice thing about this recipe is that it makes more than you’ll need for the tart, so you have an excuse to warm the caramel for an ice cream topping, eat it with apple slices, or just sample it liberally from the jar. Most recipes are pretty similar and don’t call for vanilla, but I have a ridiculous amount of vanilla bean pods in the cupboard, so I simmered one with the cream, and it really added a nice depth to the final product. (If you ever need vanilla beans — especially in bulk — but can’t bring yourself to purchase them at the extortionate prices charged by grocery stores, do what I do and order from ebay. Seriously.)

This tart can really use a generous application of salted caramel (and it’s great drizzled over the individual slices), so don’t be shy when you’re building it. The apples aren’t tossed with sugar before assembly, so if you prefer a sweeter tart, be generous.

Apples and Assembly

To make the tart a bit prettier than I normally would, I left the apple skins on and cut them into thin slices before arranging them in the pan in half-apple groupings. Instead of trying my patience with a knife, I set my mandoline to cut 1/8″ slices, which ensured even slices and sped up the process considerably. But even with the mandoline, it took a little while to slice five apples, so I dipped the fresh slices into a mixture of citric acid and water to keep them from browning. You could use plenty of lemon juice in the water instead of the citric acid powder, but I’ve never had much luck with it. Neither one is strictly necessary since browning won’t harm the flavor, but it makes for a nice presentation.

My 9″ tart pan was perfect for this application, but you can use a pie plate if you prefer. Just don’t use deep dish unless you increase all ingredients. Even so, the apples may look a bit meager in there after baking.

The only difficulty with assembly was taking pictures between each step, but when the photographic muse calls, one must listen! In fact, I created a little animation of the process, if you’d like to take a look:

While making a pretty tart takes a little more effort than my go-to apple crisp, the extra time spent in the kitchen is certainly worth it! Nothing says fall like a delicious apple dessert.

Gluten-Free Salted Caramel Apple Tart

An apple tart with soul – salted caramel adds depth and the nutty almond crust plays beautifully with the other flavors in this perfect fall dessert.

Course: Dessert
Ingredients
Salted Caramel
  • 1 cup granulated sugar
  • 1/4 cup water
  • 2/3 cup heavy cream
  • 1 vanilla bean split lengthwise
  • 2 tablespoons unsalted butter cut into small cubes
  • 3/4 teaspoon kosher salt
Apple Tart
  • 4-5 baking apples (like Cortland or Granny Smith)
  • citric acid
  • water
  • 1 tablespoon unsalted butter melted
  • 2 teaspoons cinnamon sugar optional, for sprinkling
Instructions
Almond Flour Crust
  1. Follow instructions at the blog post listed in Recipe Notes (below) for tart preparation. After chilling dough in refrigerator, roll out between two sheets of parchment paper, remove one piece of paper and turn dough over and into a 9" tart pan with removable bottom. Remove top sheet of parchment and press dough into the pan. Trim excess dough either with a knife or by pressing dough against the edge of the pan. Refrigerate until you're ready to assemble the tart.

Salted Caramel
  1. In a 2-quart saucepan, combine granulated sugar and water over medium heat and cook, without stirring, until a deep amber color. 

  2. While syrup is cooking, simmer heavy cream and vanilla bean in a small pot. Remove vanilla bean just before proceeding with the next step.

  3. Once sugar reaches the proper color, whisk in heavy cream, taking care as you do because it will foam up. Continue whisking over low heat for 2-3 minutes, or until smooth.

  4. Remove saucepan from heat and whisk in butter and salt. Allow to cool before proceeding with apple tart assembly.

  5. Mix a small bowl of water and citric acid according to instructions on the package and set next to your work station.

Apple Tart
  1. Cut apples in half lengthwise and core. To slice, turn an apple half on its side so the apple is taller than it is wide, with the cut half is facing away from you. With a mandoline set to 1/8", slice the apples as far down as you can go without endangering your fingers.

  2. Stack the apple slices in order so they re-form the apple half. Dip in citric acid & water and set aside on a plate or cutting board. Repeat with remaining apples.

  3. To assemble, remove prepared tart shell from the refrigerator and add 3-4 large spoonfuls of salted caramel to the base of the tart. Spread with a butter knife or small offset spatula. 

  4. Arrange sliced apple halves decoratively into tart shell. See video for how I did it, or just wing it. Fill in any open spaces with smaller groupings of apple slices.

  5. Brush apples with melted butter and sprinkle with cinnamon sugar, if using.

  6. Place tart shell on a foil-lined baking sheet and bake at 350°F for approximately 60-75 minutes (possibly more), or until a skewer inserts easily into the thickest apple sections with little resistance. If tart dough starts to brown too much, wrap the edges in foil.

  7. Cool in tart pan to room temperature before serving. Drizzle with salted caramel sauce for a decadent presentation.
