Key Ingredient Notes

The success of your Cheddar, Potato & Caramelized Onion Galette lies in selecting and preparing your ingredients with a little love and attention.

The Magic of Caramelized Onions

This is arguably the soul of the galette. Do NOT rush this step. Caramelizing onions is a slow process that transforms their sharp, pungent flavor into a deep, sweet, and umami-rich essence. Use yellow or sweet onions for the best results. Slice them thinly and cook them over low heat for a good 30-45 minutes, stirring occasionally, until they are a rich, golden brown and almost jam-like. This patience is rewarded with incredible depth of flavor that defines the Cheddar, Potato & Caramelized Onion Galette.

Choosing and Preparing Your Potatoes

For this galette, I recommend using Yukon Gold or Russet potatoes. Yukon Golds offer a creamy texture and buttery flavor, while Russets become wonderfully tender. The key is to slice them very thinly, ideally using a mandoline, to ensure they cook through evenly and quickly within the galette. Aim for slices about 1/8-inch thick. A quick soak in cold water and then patting them thoroughly dry helps remove excess starch and prevents them from sticking together.

The Star Cheese: Sharp Cheddar

While you can certainly experiment with other cheeses, a good quality sharp cheddar is essential for the classic Cheddar, Potato & Caramelized Onion Galette. Its robust, tangy flavor cuts through the sweetness of the caramelized onions and the richness of the potatoes, creating a perfect balance. Freshly grated cheddar melts beautifully and has a superior flavor compared to pre-shredded varieties. Don’t be shy with it!

Step-by-Step Guide with Pro Tips

Crafting this delightful Cheddar, Potato & Caramelized Onion Galette is a joyous process. Follow these steps for a perfect result every time.

Pro Tip: Achieving Perfectly Caramelized Onions

For the best caramelization, use a heavy-bottomed pan and cook the onions on medium-low heat. Add a pinch of salt to draw out moisture and a tiny bit of sugar to enhance browning. If they start to stick, add a tablespoon of water or broth to deglaze the pan and scrape up any flavorful brown bits. The longer and slower you cook them, the richer the flavor.

Pro Tip: Thin Potato Slices are Key

A mandoline slicer is your best friend here. If you don’t have one, use your sharpest knife and take your time to ensure uniform, thin slices. This guarantees the potatoes cook evenly and achieve a tender texture without becoming mushy.

Here’s how to assemble your glorious galette:

1. Step 1: Prepare the pastry. If using store-bought puff pastry, roll it out on a lightly floured surface into a 12-14 inch circle. If making homemade crust (like a savory pastry dough), roll it out to the same dimension. Transfer the dough to a parchment-lined baking sheet.
2. Step 2: Prepare the caramelized onions. Heat butter and olive oil in a large skillet over medium-low heat. Add sliced onions and cook, stirring occasionally, for 30-45 minutes until deeply golden brown and soft. Season with salt and pepper. Set aside to cool slightly.
3. Step 3: Prepare the potatoes. Slice potatoes very thinly (1/8 inch thick) using a mandoline or sharp knife. Toss them in a bowl with olive oil, minced garlic, fresh thyme, salt, and black pepper.
4. Step 4: Assemble the galette. Spread the cooled caramelized onions evenly over the pastry dough, leaving a 2-inch border clean around the edges.
5. Step 5: Arrange the potatoes. Shingle the seasoned potato slices over the caramelized onions in concentric circles, overlapping them slightly.
6. Step 6: Add the cheese. Sprinkle the grated sharp cheddar cheese generously over the potatoes.
7. Step 7: Fold the edges. Carefully fold the 2-inch pastry border up over the filling, crimping it gently to create a rustic edge. The center of the galette will remain open.
8. Step 8: Egg wash and bake. In a small bowl, whisk an egg with a tablespoon of water to create an egg wash. Brush the exposed pastry edges with the egg wash.
9. Step 9: Bake the Cheddar, Potato & Caramelized Onion Galette in a preheated oven at 400°F (200°C) for 35-45 minutes, or until the crust is golden brown and the potatoes are tender when pierced with a knife.
10. Step 10: Cool and serve. Let the galette cool on the baking sheet for 10-15 minutes before slicing and serving. This allows the filling to set slightly.

Variations & Serving Suggestions

The beauty of the Cheddar, Potato & Caramelized Onion Galette lies in its adaptability. Here are some ideas to make it your own:

• Add a Protein Boost: Crispy bacon bits or diced ham would make a delicious addition to the filling, especially scattered over the caramelized onions before adding the potatoes.
• Cheese Swap: While cheddar is classic, consider Gruyere, smoked gouda, or a blend of cheeses for different flavor profiles. A sprinkle of Parmesan for a salty crust is also delightful.
• Herbacious Notes: In addition to thyme, fresh rosemary or sage would complement the potatoes and onions beautifully.
• Spicy Kick: A pinch of red pepper flakes mixed with the potatoes or a drizzle of hot honey (like in this Blueberry Brie Grilled Cheese) just before serving could add an exciting zing.
• Serving Suggestions: Serve your Cheddar, Potato & Caramelized Onion Galette as a main dish with a simple green salad dressed with a vinaigrette. It also makes an excellent brunch item, a sophisticated appetizer cut into smaller wedges, or a hearty side for roasted chicken or pork. Leftovers, stored in an airtight container like these Basics Glass Food Storage containers, are fantastic reheated or enjoyed at room temperature for lunch the next day.

Cheddar, Potato & Caramelized Onion Galette

Pin Recipe

A rustic and elegant savory galette featuring tender thinly sliced potatoes, sweet deeply caramelized onions, and sharp cheddar cheese, all encased in a flaky, golden pastry crust. Perfect for a cozy meal or impressive entertaining.

• Total Time: 1 hour 15 minutes
• Yield: 8 servings 1x

Ingredients

Scale 1x2x3x

1 sheet (14 oz / 397g) puff pastry, thawed, or homemade pie crust
2 tablespoons olive oil, divided
1 tablespoon unsalted butter
2 large yellow onions, thinly sliced (about 4 cups)
1/2 teaspoon salt, plus more to taste
1/4 teaspoon black pepper, plus more to taste
2 medium Yukon Gold or Russet potatoes (about 1.5 lbs), peeled and very thinly sliced (1/8 inch)
2 cloves garlic, minced
1 teaspoon fresh thyme leaves, chopped
1.5 cups (about 6 oz) sharp cheddar cheese, grated
1 large egg, for egg wash
1 tablespoon water, for egg wash

Instructions

Step 1: Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper. If using puff pastry, unroll it onto the prepared baking sheet. If using homemade dough, roll it out into a 12-14 inch circle and transfer to the baking sheet.
Step 2: Prepare the caramelized onions. Heat 1 tablespoon of olive oil and the butter in a large skillet over medium-low heat. Add the sliced onions, 1/4 teaspoon of salt, and 1/8 teaspoon of pepper. Cook, stirring occasionally, for 30-45 minutes until the onions are deeply golden brown and very soft. Remove from heat and let cool slightly.
Step 3: Prepare the potatoes. In a medium bowl, toss the thinly sliced potatoes with the remaining 1 tablespoon of olive oil, minced garlic, chopped fresh thyme, 1/4 teaspoon of salt, and 1/8 teaspoon of black pepper. Ensure all slices are lightly coated.
Step 4: Assemble the galette. Spread the cooled caramelized onions evenly over the pastry dough, leaving a 2-inch border around the edges clean. This border will be folded over to form the crust.
Step 5: Arrange the potatoes. Shingle the seasoned potato slices over the caramelized onions in concentric circles, slightly overlapping them. Try to create an appealing pattern.
Step 6: Add the cheese. Evenly sprinkle the grated sharp cheddar cheese over the potato layer. Don’t be shy; the cheese adds crucial flavor and helps bind the filling.
Step 7: Fold the edges. Carefully fold the 2-inch pastry border up over the filling, crimping it gently every few inches to create a rustic, free-form crust. The center of the galette with the filling will remain exposed.
Step 8: Apply egg wash. In a small bowl, whisk the egg with 1 tablespoon of water to create an egg wash. Brush the exposed pastry edges thoroughly with the egg wash for a golden, shiny crust.
Step 9: Bake the galette for 35-45 minutes, or until the crust is deeply golden brown and the potatoes are tender when pierced with a fork. If the crust browns too quickly, you can loosely tent it with foil.
Step 10: Cool and serve. Remove the Cheddar, Potato & Caramelized Onion Galette from the oven and let it cool on the baking sheet for 10-15 minutes before carefully sliding it onto a cutting board. Slice into wedges and serve warm. Enjoy!

Notes

For best results, slice potatoes as uniformly thin as possible. A mandoline is highly recommended. You can prepare the caramelized onions up to 2 days in advance and store them in the refrigerator to save time.
