Can I make the Cheddar, Potato & Caramelized Onion Galette ahead of time?

Yes, you can prepare the caramelized onions a day or two in advance and store them in an airtight container in the refrigerator. You can also assemble the entire galette (without baking) up to 4 hours ahead and keep it refrigerated. Let it come to room temperature for about 15-20 minutes before baking as directed.

What's the best way to reheat leftover Cheddar, Potato & Caramelized Onion Galette?

To reheat, place slices of the galette on a baking sheet and warm them in a preheated oven at 300u00b0F (150u00b0C) for 10-15 minutes, or until heated through and the crust crisps up again. You can also reheat individual slices in a toaster oven.

Can I use different types of cheese or potatoes?

Absolutely! For cheese, Gruyere, smoked gouda, or a mix of cheddar and Parmesan would be delicious. For potatoes, waxy varieties like red bliss or new potatoes work well. Avoid very starchy potatoes like Russets, as they can become too mushy. Just ensure they are sliced very thinly for even cooking.

How do I prevent the galette crust from getting soggy?

To prevent a soggy crust, make sure your caramelized onions are not too wet (cook them until any liquid has evaporated). You can also sprinkle a thin layer of breadcrumbs or a little extra cheese on the dough before adding the onions to create a barrier. Ensuring your oven is fully preheated and baking on a lower rack can also help crisp the bottom.

Instructions

Step 1: Prepare the Pie Dough. If making homemade dough, prepare it and chill for at least 30 minutes. If using store-bought, let it come to room temperature slightly for easier rolling. Preheat your oven to 375°F (190°C).
Step 2: Caramelize the Onions. In a large skillet, melt butter and olive oil over medium-low heat. Add the thinly sliced onions, 1/2 tsp salt, and 1/4 tsp pepper. Cook slowly, stirring occasionally, for 30-40 minutes, until the onions are deeply golden brown and very soft. Set aside to cool slightly.
Step 3: Prepare the Potatoes. While onions are cooking, thinly slice the Yukon Gold potatoes. A mandoline is excellent for this to ensure even thickness. Place slices in a bowl and set aside.
Step 4: Roll out the Dough. On a lightly floured surface, roll out your pie dough into a roughly 12-14 inch circle. Carefully transfer the dough to a baking sheet lined with parchment paper.
Step 5: Assemble the Galette. Spread the cooled caramelized onions evenly over the dough, leaving a 2-inch border all around. Arrange the thinly sliced potatoes over the onions, overlapping them slightly. Season the potatoes generously with salt and pepper. Sprinkle the shredded cheddar cheese evenly over the potatoes.
Step 6: Fold the Edges. Carefully fold the edges of the dough over the filling, creating pleats as you go. Don't worry about perfection; the rustic look is part of the charm of this Cheddar, Potato & Caramelized Onion Galette.
Step 7: Prepare Egg Wash and Bake. In a small bowl, whisk together the egg and water to make an egg wash. Brush the exposed pastry crust with the egg wash. Bake in the preheated oven for 45-60 minutes, or until the crust is golden brown and the potatoes are tender when pierced with a fork. If the crust starts to brown too quickly, loosely tent the galette with aluminum foil.
Step 8: Rest and Serve. Remove the Cheddar, Potato & Caramelized Onion Galette from the oven and let it rest on the baking sheet for 10-15 minutes before slicing and serving. Garnish with fresh thyme or rosemary, if desired.

Notes

For the best flavor, use a good quality sharp cheddar cheese and don't rush the caramelization of the onions. If you're short on time, a good quality store-bought pie crust works perfectly. This galette is delicious warm or at room temperature.
