Classic Bread Crust Potato Herb Tart

Traditional Bread Crust Potato Herb Tart, featuring shallots, thyme, and grated hard cheese represents the pinnacle of comfort cuisine; bread, potatoes, and cheese!

A Affectionate Note To The Modest Potato

This potato herb tart serves as my affectionate note to the modest potato, an old-fashioned dish reinterpreted with care and warmth. Drawing inspiration from a classic, I’ve opted to shift away from a fragile pastry crust and rather stabilize the dish with a soft, yeast-leavened bread dough. The outcome is something more substantial, more abundant, ideal for both chilly evenings and lengthy summer gatherings.

What renders this tart particularly gratifying begins even before the oven is warmed. The potatoes are slightly blanched, just until tender, and their cooking water, thick with starch and mineral richness, is retained and cooled. That very water transforms into the base of the bread dough. It’s a slight, nearly instinctive decision, but one that alters the crust significantly. The dough bakes up with a gentle chew, a hint of sweetness, and a complexity of flavor that solely arises from attending to every aspect of the process with diligence.

A Bread Crust Tart That Incorporates The Potato

In France, a ‘Tartine’ refers to an open-faced sandwich; a slice of bread topped with either sweet or savory ingredients. For the winter festivities, I aimed to craft an elevated Tartine, featuring potatoes as my savory element. 

As the dough rises, the filling is assembled in layers of warmth and brightness: thinly cut potatoes, slowly softened shallots, fresh herbs, and cheese that melts into the crevices. There’s no weightiness here, just richness equilibrated by aromas and the earthy clarity of herbs. Each mouthful provides contrast: the tender potatoes, the savory filling, and the bread crust that binds everything together like a kept promise.

Before long, I had created the ultimate comforting meal bite, devoid of my potatoes drowning in creamy sauces. 

This bread dough rises within an hour, then layered with blanched potato slices, drizzled with olive oil, and topped with shallots, cheese, and herbs. Baked to a crunchy crusted perfection, I realized this dish would be a success on the holiday dining table. 

A Timeless French Potato Tart

My bread-crusted potato tart is simply an enhanced ‘Tourte aux Pommes de Terre’; an open-faced potato sandwich!

The tart is baked in a pan with a removable bottom, resembling a fancy loaf of bread. Who doesn’t relish melted cheese, salty potatoes, and a crispy bite of homemade bread, all in one mouthful!

Our Enthusiasm For Potatoes

Whether whipped, roasted, or fried, the enthusiasm for potatoes is genuine! 

A generous bowl of mashed potatoes on any dinner table looks like a celebration, especially knowing there will be ample leftovers for tomorrow’s Shepherd’s Pie.

Short on time to peel, slice, dice, and fuss with the potatoes for a fabulous meal after a long workday? Just toss them in olive oil with plenty of herbs, bake on a sheet pan until they are golden outside and creamy within.

More Potatoes With Herbs To Adore

Hasselback Potatoes (my most frequented recipe) present a big, unpeeled potato, with numerous cuts partway through, filled with goodies, wrapped in foil, and baked later. 

Similar to this easy-to-make potato is Twice Cooked Potatoes; baked without fuss one day, stuffed with whatever the next, often making this a complete meal in itself.

Summertime Potatoes

However, potatoes aren’t confined to the chill of winter. My Potato Salad With Homemade Mayonnaise is another of my most popular recipes; particularly for the Mayonnaise.

Crafting homemade mayonnaise is the simplest sauce or condiment to prepare and will leave you questioning what’s actually in the mayo you purchase at the store!

The Festive Potato

Let me share one more (though there are many), potato recipe that I’ve also enhanced for the festive table.

Potato Latkes topped with a Flawlessly Poached Egg and smoked salmon. I present this dish during my most cherished family brunches.

You’ll often spot images of this on my Instagram or Facebook page on Christmas morning, by the fire with a glass of bubbly!

Potato Alternatives

Swap potatoes for something else? No way; we attempt it but we all agree that the big ole spud is scrumptious no matter how we prepare it.

A roasted cauliflower might capture my interest, perhaps even a rutabaga, but… nah, truly, there is no match for a spud, but that’s just my opinion.

What Is A Tart?

When we initially consider a tart, we typically envision a dessert; am I correct? However, a tart can be either sweet or savory.

So, what precisely is a tart? In brief, a tart is a baked item with a filling atop a pastry foundation with an exposed top, not covered by pastry. This defines a tart, whether sweet or savory.

While I possess a lengthy collection of marvelous sweet tarts in my recipe arsenal, I often employ a Pie Hack for individual-sized tarts:

• Grandma’s Bourbon Pecan Tart – is abundantly filled with pecans, both in the crust and the filling; which is a tad boozy with classic southern Bourbon.
• Strawberry Tart – Fresh Farm Strawberry Tarts, of buttery pastry, cream or coconut milk custard, and an abundance of fresh strawberries, are a delightful way to embrace spring!
• Blueberry Orange Tart – simply features numerous blueberries layered atop a thin orange blossom custard, baked as individual servings.
• Fig Tart – the very tart I created for the finale of The Great American Recipe on PBS.

I am chiefly remembered for a television tart I prepared for the judges and spectators; Potato Crusted Herb Quiche. This dish garnered me accolades from the judges on The Great American Recipe with PBS!

Is it a tart? We refer to it as a quiche, but essentially, it is a filling baked within a crust that has an open top, so call it what you wish!

Potato Tart Instead Of Potato Casserole?

I didn’t grow up with casseroles in my mother’s kitchen, unless it was in the form of lasagna.

When I first discovered what a casserole entailed, a collection of ingredients tossed into one baking vessel, baked and served in that vessel, I was appalled.

A casserole, to me, does not appear appetizing, yet I appreciate the concept and simplicity of incorporating several ingredients into a one-bite dish. A perfect solution for busy mothers, I suppose.

Thus, I devised a potato tart, with layers of finely sliced potatoes, interspersed with shallots, cheese, and fresh herbs, baked nestled inside of a homemade bread dough. What an impressive one-bite dish that appears fancy as well!

Bread Crust vs Puff Pastry

Do you know what’s found in puff pastry? Lots and lots of butter! Certainly, it tastes amazing and bakes to an almost croissant-like consistency, but I didn’t want to expend all my calories on just the crust.

Instead, I chose a straightforward bread dough that anyone can create. The key to making a bread dough that rises quickly is potato water; Potato Bread.

The potatoes had to be tenderized in boiling water for merely a couple of minutes, providing me the potato water for my pastry.

Budget Friendly Bread Crust

If you haven’t purchased puff pastry in some time, you may be astonished when you check the price. Last time I checked, it was approximately eight dollars for a box of puff pastry, likely ten by this point.

Nope, I intend to create something more budget-friendly and not packed with the calories of butter. I’ll reserve those calories for the cheese that will crown the tart!

How To Prepare Bread Crust Potato Tart

Since there are three stages involved in crafting this tart, each step can be completed at different times; as it accommodates your timetable.

Initially, the potatoes are cut thinly, using a mandolin or a sharp knife. These slices are placed into a pot of boiling water for just a couple of minutes to make them gentle but not fully cooked.

Take the potatoes out of the boiling water, immerse them in a bowl of ice water, drain them and set aside until you are ready to utilize them. This stage can be performed a day in advance if necessary.

The second phase involves utilizing the cooled potato water to create a bread dough with yeast and flour. Once the dough is prepared, it rises swiftly due to the starch present in the potato water.

Lastly, to assemble everything, the bread dough is rolled out and shaped into a removable bottom tart pan.

Arrange the potato slices atop the bread dough. Drizzle with olive oil, sprinkle with salt and grated cheese, then finish generously with fresh thyme before baking to achieve golden perfection.

Required Equipment

• Mandoline slicer or sharp knife – Thin, uniform potato slices are crucial for a tart that bakes beautifully and layers smoothly. A mandoline provides quick, consistent results, but a sharp knife and a steady hand work just as effectively; this is a recipe that values both efficiency and tradition.
• Cutting board – A basic yet vital workspace. This is where the transition commences: potatoes sliced, shallots softened, herbs collected and chopped.
• Measuring cup and measuring spoons – Bread dough benefits from careful measurement. Ensuring the correct proportions yields a dough that is pliable and balanced, especially when working with potato water, which introduces its own subtle variables.
• Rectangle Tart pan – My preferred choice. A rectangular pan slices cleanly and serves nicely, making it perfect for sharing. Unlike a round pan, it lends itself to elegant portions, ideal for a gathering where presentation is just as important as flavor.
• Medium size saucepan – Utilized to blanch the potatoes just until soft; this pot also creates the starchy potato water that will later enhance the bread dough.
• Slotted spoon – Essential for safely lifting the hot potatoes from the boiling water while preserving that valuable cooking liquid for the dough.
• 2 large bowls and a small bowl – One bowl is designated for preparing the bread dough, spacious enough for mixing and rising. The other keeps an ice bath, which quickly stops the cooking of the potatoes and maintains their texture. The small bowl is ideal for yeast, herbs, and small measured ingredients.
• Wooden spoon – My favorite tool for blending bread dough. There’s an inherent connection to using wood; it feels more deliberate, more engaged, and is perfectly suited for yeast-based recipes.
• Kitchen towel – Laid out to gently dry the blanched potatoes, ensuring the tart remains layered and never soggy. Simple, effective, essential.
• Cheese grater – If your hard cheese isn’t grated already, this tool guarantees fresh shreds that melt uniformly and enhance the tart’s flavor.
• Stovetop and oven – The stovetop starts the process, boiling potatoes, softening aromatics. The oven completes it, turning…
• modest components into a golden, aromatic tart that feels both primitive and elegant.

Required Ingredients

• Potatoes – The core of the tart and the essence of the crust. Potatoes provide comfort, substance, and a subtle earthiness that anchors the entire creation. Blanched just until soft, they transform into smooth layers in the filling, while the starchy cooking liquid silently adds flavor and structure to the bread dough. Nothing is wasted; everything is esteemed.
• Water – Not merely a supporting role here. The reserved potato liquid carries minerals and natural starch, enriching the dough with subtle sweetness and a delicate crumb. It’s a reminder that some of the most significant ingredients are those we often learn to discard.
• Yeast – Yeast infuses life into the crust, quite literally. It converts simple flour and water into something warm, aromatic, and sustaining. This is not a crisp pastry base but a living dough that rises, breathes, and bakes into a soft, rustic foundation for the tart.
• Flour – Flour provides the tart with its framework and strength. It retains the moisture from the potato water, the richness from olive oil, and the gradual magic of yeast fermentation. The outcome is a crust that is strong yet gentle, designed to be torn and enjoyed.
• Olive Oil – Olive oil enriches the dough and offers a subtle fruitiness that connects crust and filling. In the tart itself, it conveys flavor, softens edges, and imparts a modest richness without weight, sun-warmed and grounding all at once.
• Garlic – Garlic adds complexity and warmth, particularly when gently sautéed. It fragrances the filling without overwhelming it, providing a savory base note that enriches the potatoes and herbs, making them feel more wholesome and complete.
• Shallot – Sweeter and more refined than onion, shallots integrate into the tart with finesse. They supply balance, softening the earthiness of the potatoes and complementing the cheese without stealing the attention.
• Thyme – Thyme is the herb that suggestively complements rather than dominates. Its earthy, slightly floral tones harmonize beautifully with potatoes and bread, giving the tart a timeless, countryside quality that feels at ease in both winter and summer.
• Salt – Salt acts as the subtle enhancer, the component that enlivens everything else. It sharpens flavors, fortifies the dough, and ensures that every bite tastes intentional instead of bland.
• Grated Hard Cheese – The ultimate layer of indulgence. A firm, well-aged cheese imparts saltiness, nuttiness, and richness, melting into the potatoes and uniting the filling. It adds opulence without excess, finishing the tart with a savory touch that lingers.

This is not a tart intended to be overly precious. It’s designed to be sliced generously, served warm or at room temperature, and relished throughout the seasons. In winter, it feels grounding and nourishing; in summer, paired with greens and a glass of something refreshing, it feels rustic and festive. It’s the kind of meal that reminds us how delightful food can be when we take the time to allow simple ingredients to reveal their potential.
