Gluten Free Caramelized Onion & Gruyere Crackers

These gluten free caramelized onion and gruyere crackers are one of my favorite snacks to make. They’re savory, crispy, and have this deep sweet onion flavor that you just can’t stop eating.

The base is made with almond flour and tapioca starch, so they’re completely gluten free. No weird aftertaste, no crumbly texture. Just proper crackers that snap when you break them.

What really makes these special is the caramelized onions. You cook them low and slow until they turn deep golden and almost jammy. That sweetness pairs so well with the nutty gruyere cheese baked right into the dough.

They come together pretty easily too. Mix everything into a dough, roll it thin, score it into squares, and bake. That’s basically it.

Whether you’re gluten free by choice or necessity, these crackers are worth making. They’re great on their own, with cheese, or alongside a bowl of soup.

Ingredients

• 1 tbsp Unsalted Butter
• 1 Medium Yellow Onion, finely diced
• 1/4 tsp Salt (for onion)
• 1 1/2 cups Almond Flour
• 1/2 cup Finely Shredded Gruyere Cheese
• 2 tbsp Tapioca Starch
• 1/2 tsp Salt
• 1/4 tsp Black Pepper
• 1/4 tsp Fresh Thyme Leaves
• 1 Large Egg White

How to Make

Step 1

Melt the butter in a skillet over medium-low heat. Add the diced onion and 1/4 teaspoon salt. Cook, stirring occasionally, for 15 to 20 minutes until the onions are deep golden brown and jammy. Let them cool completely before using.

Step 2

Preheat your oven to 325F and line a large baking sheet with parchment paper.

Step 3

In a large bowl, combine the almond flour, shredded gruyere, tapioca starch, salt, black pepper, and thyme leaves. Add the cooled caramelized onions and the egg white.

Stir with a fork, then knead with your hands until a smooth dough forms. The onions should be distributed throughout.

Step 4

Place the dough between two sheets of parchment paper and roll out to about 1/8 inch thickness, keeping it as even as possible.

Step 5

Remove the top parchment and score the dough into small squares or rectangles. Poke each cracker once with a fork.

Step 6

Bake for 16 to 20 minutes, until the crackers are golden brown and the edges are deeply toasted and crisp. The gruyere will bubble slightly and add beautiful golden spots.

Step 7

Let the crackers cool completely on the baking sheet before breaking them apart. The sweet onion and nutty gruyere flavor deepens as they cool. Store in an airtight container at room temperature.

My Tips

Cool the Onions Completely

This is the most important step people rush through. If the onions are even a little warm when you mix them into the dough, the almond flour and gruyere will get oily and the dough will be too soft to roll out.

Spread the caramelized onions on a plate so they cool faster. Putting them in a bowl means the ones in the middle stay warm for a long time.

You want them fully at room temperature before they go anywhere near the rest of the ingredients.

Grate the Gruyere as Fine as You Can

Use the smallest holes on your box grater for the gruyere. Big shreds won’t blend into the dough properly, and you’ll end up with uneven crackers that have melty cheese pockets in some spots and none in others.

Finely shredded gruyere melts evenly during baking and gives every cracker that nutty, golden cheese flavor. It also makes rolling the dough much easier because the texture stays smooth.

If the cheese is sticking to your grater, pop it in the freezer for 10 minutes first. Cold gruyere grates much cleaner.

Roll the Dough Evenly to 1/8 Inch

Almond flour dough doesn’t have gluten holding it together, so it bakes differently than regular cracker dough. If some parts are thicker than others, the thin parts will burn while the thick parts stay soft and chewy.

Rolling between two sheets of parchment is the move here. It keeps the dough from sticking to everything and lets you peel the top sheet off cleanly for scoring.

If the dough cracks at the edges while rolling, just press it back together with your fingers. It’s very forgiving since the egg white and tapioca starch act as binders.

FAQ

Can I use a different cheese instead of Gruyere?

Gruyere gives these crackers their signature nutty, slightly sweet flavor that pairs perfectly with the caramelized onions, but you can swap it for other firm, flavorful cheeses. Aged cheddar, Comte, or Parmesan all work nicely.

Just make sure whatever cheese you pick is finely shredded so it blends smoothly into the dough. Softer cheeses like mozzarella or brie won’t give you the same crisp texture.
