Ingredients for potato tart
Buttery crust meets melt-in-your-mouth cheese filling—just 13 ingredients for restaurant-quality tart perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for light texture |
| Fine Yellow Cornmeal 🌽 | 1 cup | Stone-ground preferred |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for flakiness |
| Ice Water 💧 | ¼ cup | Chilled for crisp crust |
| Diamond Crystal Kosher Salt 🧂 | 1 tsp | Fine grain preferred |
| Russet Potatoes 🥔 | 2 lbs | Starchy variety recommended |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Sharp White Cheddar Cheese 🧀 | 1 ½ cups | Shredded, block preferred |
| Gruyère Cheese 🧀 | 1 cup | Freshly grated for nutty flavor |
| Extra-Sharp White Cheddar Cheese 🧀 | ½ cup | Shredded, for extra tang |

The crust demands precision: stone-ground cornmeal from Bob’s Red Mill delivers the best texture, while cold butter ensures flakiness. For the filling, Gruyère is non-negotiable—its nutty depth elevates everything. Russet potatoes (not Yukon Golds) give the best starch-to-moisture ratio. Pre-shredded cheese? Toss it—it contains anti-caking agents that ruin melt. The Diamond Crystal kosher salt is key here; its fine grains dissolve perfectly without overpowering. Pro tip: Chill your pie dish before adding the dough for even baking.
No cornmeal? Fine semolina or crushed graham crackers work in a pinch, though texture will differ. Substituting cheddar? Add 0.25 cup extra sharp to compensate for Gruyère’s absence. Heavy cream too rich? Half-and-half or whole milk keeps it creamy without overwhelming. For the potatoes, microwave 5 minutes before boiling to cut cooking time. The crust can be pre-baked for 10 minutes if you’re prepping ahead—just cool completely before adding filling to prevent sogginess. Garlic powder short on flavor? 1/4 tsp fresh minced garlic in the filling adds complexity.
Assemble the tart up to 24 hours ahead—cover tightly and refrigerate. The crust stays crisp at room temperature for 4 hours, but beyond that, warm slightly before serving. Leftovers? Reheat covered at 350°F for 10-12 minutes until bubbly. For make-ahead baking, blind-bake the crust for 15 minutes at 375°F before adding filling, then bake as directed. The filling reheats beautifully, though the crust may soften slightly—just crisp it under the broiler for 2 minutes post-reheating for that golden edge.

Step-by-step instructions for potato tart recipe
This method delivers a golden crust and cheesy, pull-apart potato filling every time.
Prepare the Cornmeal Crust
In a large bowl, combine the 1.5 cups all-purpose flour and 1 cup fine yellow cornmeal. Cut in the 0.75 cup unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. Add the 1 tsp diamond crystal kosher salt and 0.5 tsp garlic powder, mixing until evenly distributed.
Gradually add the 0.25 cup ice water, sprinkling it over the dry ingredients while gently stirring with a fork. The mixture should come together when pressed, but resist overmixing—just until the dough holds its shape when pressed. Shape into a disk, wrap in plastic, and chill for 30 minutes to firm up. This resting period prevents shrinking during baking.
Roll and Blind-Bake the Crust
Preheat your oven to 375°F. On a lightly floured surface, roll the chilled dough into a 12-inch circle about ¼-inch thick. Transfer to a parchment-lined baking sheet. Prick the crust all over with a fork to prevent puffing, then line it with parchment paper and fill with pie weights or dried beans.
Bake for 15 minutes, then remove the weights and bake an additional 5 minutes until the edges begin to turn golden. The crust should be firm to the touch but not fully browned—this prevents a soggy bottom when adding the filling. Keep the crust in the oven while you prepare the potato mixture.
Cook the Potato Filling
Peel and dice the 2 lbs russet potatoes into ½-inch cubes. In a large skillet over medium heat, melt 2 tablespoons unsalted butter and add the potatoes. Cook for 8-10 minutes, stirring occasionally, until they begin to soften and release moisture. Add the 0.5 cup heavy cream and 0.5 tsp freshly ground black pepper, stirring to combine.
Reduce heat to low and let the mixture simmer gently for 5 minutes until the potatoes are tender and the liquid has mostly evaporated. Stir in the 1.5 cups sharp white cheddar cheese, 1 cup gruyère cheese, and 0.5 cup extra-sharp white cheddar cheese, mixing until fully melted and smooth. The filling should be thick but still pourable—if it's too dry, add 1 tablespoon ice water to loosen.
Assemble and Bake the Tart
Remove the partially baked crust from the oven and carefully spread the potato filling evenly over the surface, leaving a ½-inch border uncovered. Return to the oven and bake for 20-25 minutes until the filling is bubbly and the edges of the crust are deeply golden brown.
For the final touch, broil for 2-3 minutes to crisp the cheese on top. Watch closely—cheese burns quickly. Remove from the oven and let rest for 10 minutes before slicing. The center should be gooey and the crust crisp, with a perfect balance of textures in every bite.
Pro Tips For Making Potato Tart
- Chill the Dough: Let the dough rest in the fridge for at least 30 minutes before rolling—yes, even if you’re eager to get baking. I used to skip this, and my tarts would shrink unevenly in the oven. Cold butter stays firm, and the gluten relaxes, so you’ll get that crisp, even crust instead of a sad, lopsided puff.
- Toast the Cornmeal: Dry-toast the fine yellow cornmeal in a skillet over medium heat for 2–3 minutes until it smells nutty and golden. This step makes all the difference—it adds depth to the crust and prevents a bland, floury taste. (Pro move: Use a splash of butter while toasting for extra flavor.)
- Press, Don’t Roll: Press the dough into the tart pan with your fingers, not a rolling pin—this guarantees a shatteringly crisp bottom. I learned this after struggling with a soggy crust; the uneven pressure from fingers creates a tighter, more stable base. Work quickly and firmly, like you’re tucking in a picky toddler.
- Salt the Water: Mix the ice water for the dough with ½ teaspoon of kosher salt per cup—it’s non-negotiable for flavor. Unsalted butter is already mild, and skipping this step means your tart will taste flat. Trust me, your taste buds will notice the difference, especially when paired with the buttery crust.
Health benefits of these flavors
Crispy Crust Benefits
The cornmeal crust in this tart isn’t just delicious—it’s packed with fiber-rich whole grains that aid digestion and keep you full longer. Cornmeal contains about 4 grams of fiber per ¼ cup, supporting gut health and steady blood sugar levels.
The butter and cornmeal combo also provides healthy fats that your brain craves, making this tart a satisfying choice for balanced meals. 🥔
Cheesy Protein Power
The three-cheese filling delivers a high-protein punch—each serving contains roughly 18 grams of protein, thanks to the Gruyère and cheddar. Protein helps repair muscle tissue and keeps you energized, making this tart a great post-workout snack or meal addition.
The Gruyère’s lower lactose content also makes it easier to digest for those with mild lactose sensitivities.
Vitamin Boost
Russet potatoes are a nutrient powerhouse, providing vitamin C (about 25% of your daily needs per serving) and potassium (critical for heart health). Combined with the Gruyère’s vitamin A, this tart becomes a one-dish vitamin boost that supports immunity and skin health.
The heavy cream adds a touch of B vitamins, essential for energy metabolism. 💪
Low-Carb Option
While this recipe isn’t traditionally low-carb, you can easily adapt it by replacing ½ the cornmeal with almond flour (about ½ cup) and using cauliflower mash instead of potatoes.
This swap cuts carbs by 30% while keeping the creamy texture. The cheese-heavy filling remains rich and satisfying, making it a great option for keto or low-carb diets.
Comfort Food Nutrition
This tart balances indulgence with nutrition—the healthy fats from butter and cheese support brain function, while the potatoes’ potassium helps regulate blood pressure. The cornmeal’s magnesium aids muscle relaxation, perfect after a long day.
It’s the kind of dish that feels like a treat but still nourishes your body. Honestly, I rarely feel guilty eating it! 💛
Meal Prep Advantage
Unlike many comfort foods, this tart reheats beautifully without losing texture, making it ideal for meal prep. The cheese and potatoes retain moisture, so you get that gooey, restaurant-style quality even after reheating.
Plus, the crust stays crisp when stored properly—just broil for 2 minutes before serving to restore that golden edge. It’s my go-to for busy weeknights! ⏰
Nutrition facts
Frequently asked questions
Can I make this potato tart ahead of time?
Assemble the tart up to 24 hours ahead and refrigerate it covered. The crust stays crisp at room temperature for 4 hours, but for longer storage, reheat covered at 350°F for 10-12 minutes until bubbly. For best results, broil for 2 minutes after reheating to restore that golden crust.
What if I don’t have Gruyère cheese?
No problem! Substitute with 1.5 cups extra-sharp white cheddar and add 0.25 cup grated Parmesan for depth. The flavor will still be rich and tangy, though Gruyère’s nutty notes are hard to replace. For a dairy-free option, try nutritional yeast mixed with vegan cheese for a cheesy texture.
Why did my crust turn soggy?
A soggy crust usually means the filling was too wet or the crust wasn’t fully baked before adding it. Always blind-bake the crust for 15-20 minutes until golden, and let it cool completely before filling. If the filling seems too thick, add 1 tablespoon ice water to loosen—never skip this step!
Can I use sweet potatoes instead of russets?
Sweet potatoes will work, but they’re less starchy and can make the filling drier. If you do use them, reduce the heavy cream to 0.25 cup and add 1 tablespoon olive oil to the filling for extra moisture. The flavor will be slightly sweeter, so balance it with an extra 0.25 tsp black pepper.
How do I prevent the cheese from burning?
Broil the tart for just 2-3 minutes on high, watching closely to avoid burning. For a safer approach, bake at 375°F for 25 minutes until the cheese is fully melted but not browned. If the top looks too dark, cover loosely with foil for the last 5 minutes of baking.
