MINI POTATO GRATIN STACKS INGREDIENTS
You’ll need:
-
2 pounds Yukon Gold potatoes, washed and sliced into approximately ⅛-inch-thick rounds
-
¾ cup heavy whipping cream
-
1 cup freshly shredded Gruyère cheese
-
3 tablespoons salted butter, divided into 1 tablespoon for greasing the muffin tin and 2 tablespoons melted
That’s it! Four simple ingredients are all you need to make these delicious mini potato gratins.
WHAT ARE THE BEST POTATOES FOR MINI GRATIN STACKS?
Yukon Gold potatoes are an excellent choice for this recipe because they have a naturally buttery flavor and a creamy texture.
They hold their shape while baking, so the individual layers stay together when you remove the stacks from the muffin tin.
You can also use russet potatoes if that’s what you have available. They contain more starch and will give you a softer, slightly fluffier center.
For the best appearance, choose potatoes that are similar in width to the muffin cups. This makes the rounds easier to stack without having to trim too many pieces.
WHY USE GRUYÈRE CHEESE?
Gruyère is a popular choice for potato gratin because it melts beautifully and has a slightly nutty, savory flavor.
As the potatoes bake, the cheese melts between the layers and forms a golden topping.
Freshly shredded cheese works best because it melts more smoothly than many packaged shredded varieties.
If you prefer a milder flavor, you can replace the Gruyère with Swiss cheese or mozzarella. Sharp cheddar also works well if you enjoy a stronger cheesy taste.
CAN I USE MILK INSTEAD OF HEAVY CREAM?
Heavy whipping cream gives these potato stacks their rich, creamy texture.
The cream surrounds the thin potato slices as they cook, helping them become tender without drying out.
You can use half-and-half for a lighter version, but the finished gratins will be less rich and may not hold together quite as firmly.
Regular milk is not the best option for this recipe because it contains much less fat and creates a thinner sauce.
PRO TIP:
Use salted butter for this four-ingredient recipe. It adds seasoning without requiring an additional ingredient. The cheese also contributes salt, so the finished potatoes have plenty of savory flavor.
HOW TO MAKE OVEN BAKED MINI POTATO GRATIN STACKS
Making these little potato stacks is easier than you might think. The most important part is slicing the potatoes evenly so they cook at the same rate.
You’ll need a standard 12-cup muffin tin, a large mixing bowl, and a sharp knife or mandoline slicer.
STEP ONE: PREHEAT THE OVEN
Preheat your oven to 375°F (190°C).
Use 1 tablespoon of softened salted butter to thoroughly grease the bottom and sides of each muffin cup.
Make sure to coat the sides well. This will help the potatoes release from the pan after baking.
STEP TWO: PREPARE THE POTATOES
Wash and dry the potatoes. You can leave the skins on for additional texture or peel them if you prefer a smoother appearance.
Using a mandoline slicer or sharp knife, cut the potatoes into thin, even rounds approximately ⅛ inch thick.
Try to keep the slices the same thickness. Uneven pieces can cause some potatoes to become soft while others remain firm.
PRO TIP:
A mandoline makes slicing much quicker and gives you consistent potato rounds. Always use the safety guard or a cut-resistant glove to protect your fingers.
STEP THREE: COMBINE THE CREAM AND BUTTER
Melt the remaining 2 tablespoons of salted butter in a microwave-safe bowl.
Pour the heavy whipping cream into a large mixing bowl and stir in the melted butter.
Add the sliced potatoes and gently toss until all the pieces are coated with the creamy mixture.
Make sure to separate any potato slices that are sticking together so the cream can reach between them.
STEP FOUR: ASSEMBLE THE POTATO STACKS
Place a few potato slices in the bottom of each prepared muffin cup.
Sprinkle a small amount of shredded Gruyère cheese over the potatoes.
Continue adding alternating layers of potato slices and cheese until each muffin cup is filled.
The stacks can extend slightly above the top of the muffin cups because the potatoes will settle as they bake.
Divide any cream remaining in the mixing bowl evenly among the muffin cups.
STEP FIVE: ADD THE REMAINING CHEESE
Sprinkle the remaining shredded cheese over the tops of the potato stacks.
Try to keep most of the cheese on the potatoes rather than around the outside edges of the muffin tin.
This will give each stack a delicious golden topping without creating too much melted cheese on the pan.
STEP SIX: COVER AND BAKE
Place the muffin tin on a rimmed baking sheet to catch any cream that might bubble over.
Loosely cover the muffin tin with aluminum foil, leaving a little room above the potatoes.
Bake for 35 minutes.
Covering the potatoes during the first part of baking helps trap moisture, allowing the centers to become tender before the cheese topping browns.
STEP SEVEN: UNCOVER AND FINISH BAKING
Carefully remove the aluminum foil and return the muffin tin to the oven.
Bake for an additional 15 to 20 minutes, or until the tops are golden brown and the potatoes are fork-tender.
Insert a thin knife into the center of one stack. It should slide through the potato layers without resistance.
If the potatoes are still firm, continue baking for another 5 minutes and check again.
STEP EIGHT: REST AND REMOVE FROM THE PAN
Remove the muffin tin from the oven and let the potato stacks rest for 10 minutes.
This resting time allows the cream and cheese to settle, making the individual stacks easier to remove.
Run a small butter knife or silicone spatula carefully around the edges of each muffin cup.
Gently lift the stacks onto a serving platter and serve warm.
OUR RECIPE DEVELOPER SAYS
Don’t skip the resting time. The stacks will be quite soft when they first come out of the oven, but they’ll hold their shape much better after sitting for 10 minutes.
TIPS FOR MAKING THE BEST POTATO GRATIN STACKS
A few simple techniques can make a big difference in how your potato stacks turn out.
SLICE THE POTATOES EVENLY: This is the most important part of the recipe. Slices that are too thick take longer to soften, while thinner pieces cook more quickly.
DON’T RINSE THE SLICED POTATOES: Once you’ve sliced the potatoes, avoid soaking them in water. Their natural starch helps the creamy layers hold together during baking.
USE A STANDARD MUFFIN TIN: Regular-sized muffin cups work best for making individual portions. A mini muffin tin would require smaller potato rounds and a different cooking time.
SHRED YOUR OWN CHEESE: Freshly shredded Gruyère melts smoothly and creates a more even coating between the layers.
CHECK FOR DONENESS: Golden cheese doesn’t always mean the potatoes are completely cooked. Use a small knife to check the center before removing the pan from the oven.
LET THEM COOL SLIGHTLY: Removing the stacks immediately can cause the layers to slide apart. Give the potatoes enough time to firm up while they’re still warm.
For extra crispy edges, position the muffin tin on the middle oven rack during baking. This allows hot air to circulate evenly around the pan.
MINI POTATO GRATIN STACKS SUBSTITUTIONS AND ADDITIONS
These four-ingredient potato stacks are delicious as written, but there are several ways to change the flavor.
POTATOES: Substitute russet potatoes for Yukon Gold potatoes. Russets produce a softer texture and absorb the cream well.
CHEESE: Swiss cheese, sharp cheddar, Parmesan, or a combination of cheeses can replace the Gruyère.
BUTTER: Unsalted butter works if you prefer to control the amount of salt. Add a little salt to taste if you’re not keeping the recipe strictly to four ingredients.
GARLIC: For additional savory flavor, mix ½ teaspoon of garlic powder into the cream before tossing with the potatoes.
HERBS: Fresh thyme or finely chopped rosemary makes a delicious addition. Sprinkle a small amount between the potato layers before baking.
BACON: Add a little cooked, crumbled bacon between the layers for a heartier version.
Keep in mind that adding seasonings, herbs, or bacon will turn this into a recipe with more than four ingredients.
HOW TO SERVE MINI POTATO GRATIN STACKS
These cheesy potato stacks are a wonderful side dish for everything from casual dinners to special occasions.
Serve them alongside roasted chicken, grilled steak, pork chops, or baked salmon. Their creamy texture pairs especially well with savory meats.
For holiday dinners, arrange the potatoes on a large platter alongside roasted turkey, glazed carrots, green beans, and other favorite side dishes.
You can also serve them with a fresh green salad or roasted vegetables for a lighter meal.
I especially love serving these potato gratins when entertaining because the individual portions make plating dinner so easy. There’s no need to scoop potatoes from a large baking dish, and each serving has its own golden cheesy topping.
HOW TO STORE MINI POTATO GRATIN STACKS
These potatoes taste best fresh from the oven, but leftovers can be stored and reheated.
MAKE AHEAD: You can assemble the stacks up to 12 hours before baking. Cover the muffin tin tightly and refrigerate. When you’re ready to cook, remove the plastic covering and bake as directed, allowing approximately 5 to 10 additional minutes for the chilled potatoes to become tender.
IN THE FRIDGE: Let the cooked stacks cool, then transfer them to an airtight container. Refrigerate promptly and store for up to 3 to 4 days.
IN THE FREEZER: Freezing is possible, although the cream sauce can separate and the potatoes may become softer after thawing. For best texture, enjoy these fresh or refrigerated.
REHEATING: Place leftover stacks in a lightly buttered baking dish and cover loosely with foil. Heat in a 350°F oven for approximately 15 to 20 minutes, or until heated through. Remove the foil for the final few minutes to help crisp the tops.
Avoid overheating them in the microwave if you want to preserve their crispy edges.
TROUBLESHOOTING MINI POTATO GRATINS
WHY ARE MY POTATOES STILL HARD?
The slices may be too thick or the stacks may need additional baking time.
Cover the pan loosely with foil and continue baking in 5-minute increments until the potatoes are tender.
WHY ARE MY POTATO STACKS FALLING APART?
The potatoes may not have rested long enough. Let them sit in the muffin tin for 10 minutes before removing them.
WHY IS THE CREAM BUBBLING OVER?
The muffin cups may be too full. Leave a little space near the top and place a baking sheet underneath the muffin pan.
WHY IS THE CHEESE BROWNING TOO QUICKLY?
Ovens can vary in temperature. If the tops become too dark before the potatoes are cooked, loosely cover them with foil until the centers are tender.
MINI POTATO GRATIN STACKS FREQUENTLY ASKED QUESTIONS
Can I make these potatoes without a mandoline?
Yes. A sharp knife works well as long as you cut the potatoes into thin, even slices. The more consistent the slices, the more evenly they’ll cook.
Do I need to peel the potatoes?
No. Yukon Gold potatoes have thin skins that soften during baking. Leaving them on adds a little texture, but peeling them gives the gratins a smoother appearance.
Can I use a silicone muffin pan?
Yes, although a metal muffin tin generally produces better browning around the edges. Silicone pans may require a little additional baking time.
Can I double this recipe?
Absolutely. Double all four ingredients and use two standard 12-cup muffin tins. Rotate the pans halfway through baking if your oven has uneven heating.
How do I know when the potato stacks are done?
The tops should be golden brown, the cream should be bubbling gently, and a knife should slide easily through the center. Tender potatoes are the best indicator that they’re ready.
