Ingredients for potato tart
Crispy crust meets cheesy potato perfection—just 13 ingredients for golden, pull-apart magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lbs | Thinly sliced, peeled preferred |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Shredded, block preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for creaminess |
| Cornmeal 🌽 | 1 cup | Fine grind for crust |
| All-Purpose Flour 🌾 | ½ cup | For crust structure |
| Cold Unsalted Butter 🧈 | ½ cup | Cubed, chilled for flakiness |
| Large Eggs 🥚 | 1 whole | Room temperature |
| Ice Water 💧 | ¼ cup | For dough elasticity |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Garlic Powder 🧄 | ½ tsp | For subtle depth |
| Fresh Rosemary 🌿 | 1 tbsp | Finely chopped, optional |
| Butter (for greasing) 🧈 | 2 tbsp | Melted, for tart pans |
The potatoes are non-negotiable—Russets slice thin and stay firm. Trader Joe's or Whole Foods carry the best organic ones if you're splurging, but regular Russets work perfectly. Thinly slice them (about 1/8-inch thick) using a mandoline or sharp knife—uneven slices mean uneven baking. For the cheese, sharp white cheddar is key—avoid pre-shredded (it's coated with anti-caking agents). Parmigiano-Reggiano adds depth if you're feeling fancy, but cheddar alone delivers that classic pull-apart joy.
No cornmeal? Substitute half with almond flour for a nutty twist, but the crust won't be quite as crispy. Running short on heavy cream? Half-and-half or whole milk plus 1 tbsp butter works in a pinch, though the texture won't be as rich. For the crust, cold butter is critical—don't skip chilling it. If you're out of rosemary, dried thyme at half the amount gives a similar earthy note. The filling can be prepped ahead and refrigerated for 24 hours, but the crust dough should bake immediately for that perfect golden crunch.
These tarts reheat beautifully—350°F for 10-12 minutes until bubbly. Store leftovers in an airtight container for 4 days or freeze for 3 months. For make-ahead magic, assemble the tarts (without baking), wrap tightly, and freeze. Bake straight from frozen, adding 5-7 minutes to the time. The crust stays crispy even when reheated, but the filling is best served warm—trust me on this one.

Step-by-step instructions for crispy potato tarts
Here's how to create golden, pull-apart potato tarts with a perfect cornmeal crust and melty cheese center.
Prepare the Potato Filling
Preheat your oven to 375°F and grease two 9-inch tart pans with the 2 tablespoons butter (for greasing), letting the excess drip out. Peel and thinly slice the 3 lbs Russet Potatoes (about ⅛-inch thick) using a mandoline or sharp knife. You should have roughly 8 cups sliced potatoes.
Spread the potato slices evenly across the bottoms of both tart pans, overlapping slightly like shingles. This creates a sturdy base that won't fall apart when you pull out those gooey cheese pockets. The slices should fit snugly in the pans, with no gaps showing.
Make the Cheesy Cornmeal Crust
In a large bowl, combine the 1 cup Cornmeal, 0.5 cup All-Purpose Flour, 1.5 tsp Salt, 0.5 tsp Black Pepper, 0.5 tsp Garlic Powder, and 1 tbsp Fresh Rosemary. Cut the 0.5 cup Cold Unsalted Butter into small cubes and add to the dry mixture. Use a pastry cutter or your fingers to work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.
Add the 1 whole Large Eggs and 0.25 cup Ice Water to the bowl. Mix gently with a fork until just combined—don't overmix. The dough should hold together when pressed but still be crumbly. Sprinkle half of this mixture evenly over the potato layers in each tart pan, pressing down lightly to create an even base.
Assemble and Bake the Tarts
In a medium bowl, whisk together the 2 cups Sharp White Cheddar Cheese and 0.5 cup Heavy Cream until smooth. Spread half of this cheese mixture evenly over the crust in each tart pan, creating an even layer. Then sprinkle the remaining cornmeal mixture on top, pressing down gently to create a second crust layer.
Finally, spread the remaining cheese mixture over the top crust. The cheese should be visible between the crust layers when you cut into them later. Bake for 45-50 minutes until the crust is deep golden brown and the cheese is bubbling hot in the center. The tarts should pull away cleanly from the pan edges.
Rest and Serve
Remove the tarts from the oven and let them cool for 10 minutes before serving. This resting time allows the cheese to set slightly, making it easier to cut clean slices. The crust should be crispy on the outside while the inside remains tender and gooey.
Slice into wedges and serve immediately while the cheese is still warm and stretchy. These tarts are best enjoyed fresh out of the oven, with that perfect contrast of crispy crust and melty center. Store leftovers covered at room temperature for up to 2 hours, but they won't be as crispy when reheated.
Pro Tips For Making Potato Tart
- BOIL POTATOES UNIFORM: Cut Russets into even ½-inch slices—no thick chunks, no thin scraps. I learned this the hard way: uneven slices mean some parts overcook to mush while others stay raw. A mandoline helps, but a sharp knife and steady hand work too.
- GRATE CHEESE FRESH: Skip the pre-shredded bag—it’s coated with anti-caking agents that make the cheese clump and weep. Use a box grater or food processor, then pulse the cheese briefly to break it up. The texture stays smooth, and the tart won’t turn greasy.
- DON’T SKIP THE CORNMEAL: Sprinkle cornmeal directly on the hot skillet before adding the potato mixture—it creates a dry, crunchy base that prevents sticking. I used to add it later, and the bottom always came out soggy. Trust me, this is the thing that matters most.
- BAKE LOW AND SLOW: Start at 375°F (190°C) for 20 minutes, then drop to 350°F (175°C) until the center is set. High heat makes the top brown too fast while the middle stays doughy. A toothpick should come out clean, but the center should still feel slightly warm—not raw.
Troubleshooting perfect results
Soggy Crust Fix
If your crust turns out soggy instead of crispy, the issue is usually steam buildup during baking. I solve this by pre-baking the crust layer for 10 minutes at 375°F before adding the potato filling.
This creates a sturdy barrier that prevents moisture from seeping in. Another trick? Sprinkle ¼ cup breadcrumbs between the crust and potato layers for extra dryness. 🌡️
Uneven Baking
Uneven baking often happens when potato slices aren't evenly distributed or the oven temperature fluctuates. First, ensure your oven is properly calibrated—use an oven thermometer to confirm it's actually 375°F. For even cooking, rotate the tart pans halfway through baking.
If using two pans, swap their positions on the middle rack. Overcrowding the oven also causes hot spots, so leave at least 2 inches of space around each pan.
Cheese Not Melty
Cheese that stays firm instead of gooey usually means it wasn't hot enough during baking. Increase your oven temperature to 390°F for the last 10 minutes of cooking to get that perfect melt.
For extra creaminess, add 1 tbsp cream cheese to your cheese mixture—it melts more smoothly than sharp cheddar alone. Also, ensure your cheese isn't too cold when mixing; let it sit at room temperature for 15 minutes before combining with cream.
Potatoes Too Dry
Overly dry potatoes often result from baking too long or using slices that were too thin. Keep a close eye on the tarts after 35 minutes of baking—they're done when the crust is golden and the cheese is bubbling.
For extra moisture, add 2 tbsp sour cream to your cheese mixture. If your potatoes were pre-cooked (like in some recipes), skip this step entirely and use raw potatoes for the best texture.
Crust Too Crumbly
A crumbly crust usually means the butter wasn't cold enough or the dough was overmixed. Chill your butter cubes in the freezer for 10 minutes before mixing, and cut them into pea-sized pieces for even distribution.
When combining with flour, mix just until the dough holds together—overworking it develops gluten and makes the crust tough. If your crust still falls apart, add 1 tbsp ice water to bind it together.
Filling Leaking
Cheese leaking from the sides happens when the crust isn't fully set before adding the filling. First, ensure your crust is completely baked (golden brown) before adding any cheese mixture. For extra insurance, press the crust edges slightly against the pan to create a seal.
If leaks still occur, try a water crust technique: brush the crust edges with beaten egg white before adding the filling to create a natural barrier. 💡

Frequently asked questions
Can I make these potato tarts ahead of time?
Assemble the tarts completely (including the cheese filling) and refrigerate them in an airtight container for up to 24 hours before baking. For make-ahead freezing, assemble the tarts (without baking), wrap tightly, and freeze for up to 3 months. When ready to bake, add 5-7 extra minutes to the cooking time if frozen. The crust stays crispy even when reheated, but the filling is best served warm.
What's the best way to slice potatoes for even cooking?
Use a mandoline slicer for perfectly even ⅛-inch thick slices—this ensures they cook uniformly. If you don't have one, a sharp chef's knife works, but keep slices as consistent as possible. Pro tip: Soak the sliced potatoes in cold water for 5 minutes before using to remove excess starch, which helps prevent a gummy texture.
Can I substitute the cornmeal crust?
Yes! For a gluten-free option, replace the cornmeal with 1 cup almond flour (though the crust will be slightly less crispy). For a traditional pie crust, use 1 pre-made refrigerated crust, but bake it for 12 minutes before adding the filling to prevent sogginess. The cornmeal adds a subtle nutty flavor that pairs beautifully with the cheesy filling.
Why did my cheese turn out rubbery instead of gooey?
Rubbery cheese usually means it didn't melt enough during baking. Try increasing your oven temperature to 390°F for the last 10 minutes of cooking. Also, ensure your cheese is at room temperature before mixing—cold cheese melts unevenly. For extra creaminess, add 1 tbsp cream cheese to your cheese mixture before baking.
How do I serve these potato tarts?
These tarts are perfect as a side dish for holiday meals or as a hearty appetizer. Serve warm with a crisp green salad or roasted vegetables. For extra flair, garnish with fresh chives or a sprinkle of smoked paprika. They're also fantastic with a cold glass of sparkling water with lemon or a rich red wine like Cabernet Sauvignon.
