A Tart That Tells a Story
I have always loved a good potato. They are humble and honest. But this tart? It makes them feel fancy. It is like a warm, cheesy hug in a crispy crust.
My grandson calls it “pizza for grown-ups.” I still laugh at that. But he eats two slices every time. The smell of rosemary and baking cheese fills the whole house. Doesn’t that smell amazing? This matters because sharing food makes simple moments special.
The Secret is in the Crust
Do not be scared of the dough. It is just flour, butter, and cold water. The trick is to keep everything chilly. I pop my butter in the freezer for ten minutes first.
Once it looks like little pebbles, add the water. Pulse just until it clumps. Then wrap it up tight. Let it rest in the fridge. This quiet time matters. It lets the dough relax so it rolls out nicely for you.
A Cheesy Blanket for Potatoes
Now for the fun part. You mix soft cream cheese with Parmesan and mustard. It makes a rich, tangy sauce. You toss the potato slices right in it. They get all coated and ready to bake.
Fun fact: Parmesan cheese is named for Parma, Italy. They have been making it for over 800 years! I use a vegetable peeler to get my potatoes nice and thin. It works perfectly. Do you have a favorite kitchen tool you love to use?
Folding it Up With Love
Lay your dough on a baking sheet. Pile the cheesy potatoes in the middle. Then, fold the edges up and over. It does not need to be perfect. Rustic is beautiful. My first one looked a little lopsided. It tasted just as good.
A little egg wash makes the crust shine. A last sprinkle of Parmesan makes it taste golden. Then into the oven it goes. The waiting is the hardest part. What is your favorite smell from a baking oven?
Worth Every Minute
When it comes out, let it sit. I know, it is hard to wait. But if you cut it too soon, it will fall apart. Let it get just warm. Then slice it up.
The crust will be flaky. The potatoes will be tender. The flavor is savory and rich. It is perfect for a Sunday supper or a picnic. Would you serve this for a special dinner or a cozy family lunch? Tell me your plan.
Ingredients:
| Ingredient | Amount | Notes |
|---|---|---|
| All-purpose flour | 1½ cups (7½ ounces/213 grams) | For the crust |
| Table salt | 1 teaspoon, divided | Used in both crust and filling |
| Unsalted butter | 10 tablespoons | Cut into ½-inch pieces and chilled |
| Ice water | 6-7 tablespoons | |
| Cream cheese | 4 ounces (113 grams) | |
| Parmesan cheese, grated | 2 ounces (57 grams / 1 cup), divided | Used in filling and for topping |
| Extra-virgin olive oil | 2 tablespoons | |
| Dijon mustard | 2 teaspoons | |
| Fresh rosemary, minced | 1 ½ teaspoons, divided | |
| Pepper | ¼ teaspoon | |
| Large egg | 1 | Separated; yolk for filling, white for brushing crust |
| Russet potatoes | 1 pound | Peeled and sliced â…›-inch thick |
| Shallot | 1 | Sliced thin |

Instructions
Step 1: Let’s make the crust. Put your flour and half the salt in the food processor. Add the cold butter pieces. Pulse it until it looks like little pebbles. Now, pour in six tablespoons of ice water. (Using ice water keeps the crust flaky.) Process it just until a dough forms. If it’s too dry, add one more spoon of water. Scrape the sides with a spoon. I still laugh at that flour cloud.
Step 2: Time to chill. Dump the dough onto a floured counter. Gently shape it into a square. Wrap it tightly in plastic. Let it nap in the fridge for an hour. Before rolling, let it sit out for ten minutes. This makes it easier to handle. Doesn’t that smell amazing already?
Step 3: Let’s get rolling. Roll that dough into a rectangle on your floured counter. Carefully move it to a baking sheet with parchment paper. Now, soften the cream cheese in a bowl in the microwave. Whisk in half the Parmesan, oil, mustard, one teaspoon rosemary, pepper, and the rest of the salt. Then blend in the egg yolk. What’s the secret to a flaky crust? Share below!
Step 4: Mix the filling. Toss your potato and shallot slices in that creamy cheese mixture. Coat every single piece. Now, spread this filling onto the middle of your dough. Leave a nice, wide empty border all around. Sprinkle more Parmesan and the last of the rosemary on top. This is my favorite part.
Step 5: Fold and bake. Fold the dough edges up and over the filling. Overlap the corners like a cozy blanket. Beat the egg white in a little cup. Brush it all over the crust. Sprinkle the last bit of Parmesan on top. Bake until golden and the potatoes are tender. Let it cool a bit before you slice. (Letting it set makes cleaner slices.)
Creative Twists
This tart is a wonderful blank canvas. You can make it your own so easily. Try sweet potatoes instead of russets for a different flavor. Add some crispy bacon bits right into the filling. Use a different herb, like thyme, if you prefer. Which one would you try first? Comment below!
Serving & Pairing Ideas
This tart is a full meal on its own. I love it with a simple green salad. A bowl of tomato soup is also perfect for dipping. For a drink, a crisp apple cider is lovely. For the grown-ups, a glass of chilled white wine pairs beautifully. Which would you choose tonight?

Keeping Your Tart Tasty Later
Let’s talk about keeping your tart delicious. Cool it completely first. Then wrap it tightly. You can store it in the fridge for three days.
For longer storage, freeze it. Wrap slices in foil, then put them in a bag. They will keep for a month. I once froze a whole tart for my grandson’s visit. It tasted just-baked when we warmed it up!
To reheat, use your oven. This keeps the crust crisp. Warm slices at 350 degrees until hot. Batch cooking saves busy weeknights. Making two tarts is almost as easy as one.
This matters because good food shouldn’t be wasted. A ready-made meal is a gift to your future self. Have you ever tried storing it this way? Share below!
Simple Fixes for Common Hiccups
We all face little kitchen troubles. Your dough might be too crumbly. Just add another teaspoon of ice water. Knead it gently until it comes together.
The potatoes might not cook through. Slice them very thin, like a coin. I remember when my slices were too thick. The center stayed hard while the crust browned!
The crust could get soggy. Make sure your filling is not too wet. Tossing the potatoes well coats them. This creates a protective layer.
Fixing these issues builds your cooking confidence. It also makes the flavors and textures just right. Which of these problems have you run into before?
Your Quick Questions, Answered
Q: Can I make this gluten-free? A: Yes! Use a good gluten-free flour blend. The results are very tasty.
Q: Can I make it ahead? A: Absolutely. Make and chill the dough a day early. You can also assemble the whole tart and refrigerate it before baking.
Q: What are easy ingredient swaps? A: Use thyme instead of rosemary. Try a sweet potato for a different twist. Fun fact: Parmesan is one of the oldest cheeses we still eat today!
Q: Can I scale the recipe? A: You can easily double it. Just make two separate crusts. It is easier to manage.
Q: Any optional tips? A: A pinch of garlic powder in the filling is lovely. Serve with a simple green salad. Which tip will you try first?

Savory Potato and Parmesan Tart
Description
A rustic and elegant tart featuring a flaky, buttery crust filled with creamy Parmesan, rosemary, and tender potato slices.
Ingredients
Instructions
- For the Crust: In a food processor, combine the flour with half a teaspoon of salt. Add the chilled butter pieces and pulse until the mixture looks like coarse crumbs. Pour in six tablespoons of ice water and process until the dough just comes together, adding up to one more tablespoon of water if needed. Scrape the bowl as necessary.
- To Chill the Dough: Shape the dough into a square on a floured surface, wrap it tightly, and refrigerate for at least one hour. Allow it to sit at room temperature for about ten minutes before rolling.
- To Assemble: On a floured counter, roll the dough into a rectangle. Transfer it to a parchment-lined baking sheet. In a bowl, soften the cream cheese in the microwave. Whisk in half a cup of Parmesan, olive oil, Dijon mustard, one teaspoon of rosemary, pepper, and the remaining salt. Blend in the egg yolk. Toss the potato and shallot slices in this mixture until fully coated.
- To Shape and Bake: Spread the filling onto the center of the dough, leaving a wide border. Sprinkle more Parmesan and the remaining rosemary over the filling. Fold the edges of the dough over the filling, overlapping the corners. Brush the crust with a beaten egg white and sprinkle with the last of the Parmesan.
- Bake in a preheated oven until the crust is golden and the potatoes are tender. Let the tart cool on the sheet briefly, then transfer it to a rack to cool until just warm. Slice and serve.
Notes
- Bake at 400°F (200°C) for approximately 40-45 minutes. Let cool for 15-20 minutes before slicing for cleaner cuts.
