Thinly sliced potatoes layered with garlic cream, Gruyère, and Parmesan, baked right in a muffin tin into the most gorgeous, crispy-edged, creamy little stacks — this is the side dish that absolutely steals the show every single time!
THE CUTEST AND MOST IRRESISTIBLE POTATO SIDE DISH EVER!
I am completely obsessed with these Mini Potato Gratin Stacks, and honestly, once you make them, you will be too. I first made these for a holiday dinner a few years back because I wanted something a little more special than a standard casserole — and oh my goodness, they were gone in minutes. Every single person at the table was asking for the recipe before we even got to dessert. That’s always a great sign!
The best part? These little beauties are way easier to pull together than they look. The muffin tin does all the heavy lifting — it keeps each stack perfectly portioned, gives you those incredible crispy edges on every single one, and makes serving a total breeze. No scooping, no cutting, no mess. They’ve become a highly requested recipe in my house for everything from Sunday dinners to holiday spreads, and I honestly find myself making them on regular weeknights too because they come together so well with almost anything.
I love serving these alongside a simple roasted chicken or a juicy pan-seared steak with a fresh green salad on the side. It’s a complete meal that feels really special but doesn’t require hours in the kitchen. That’s my kind of cooking!
“I made these for Thanksgiving and they were the first thing to disappear from the table! My picky eaters even went back for seconds, which never happens. This is absolutely a keeper of a recipe — thank you so much!”

Frequently Asked Questions
Can I make these ahead of time?
Absolutely! You can slice your potatoes and mix the cream sauce up to a day ahead, then store them separately in the fridge until you’re ready to assemble and bake. You can also fully bake them, let them cool, and refrigerate them overnight — just reheat in a 350°F oven for about 10–12 minutes until warmed through and the edges crisp back up beautifully.
Can I freeze Mini Potato Gratin Stacks?
Yes, of course! Once fully baked and cooled, you can freeze them in a single layer on a baking sheet, then transfer them to a zip-lock bag or airtight container for up to 2 months. Reheat straight from frozen at 375°F for about 20 minutes. They won’t be quite as crispy as fresh, but they’re still absolutely delicious and so convenient for busy nights.
What kind of potatoes work best?
Yukon Gold potatoes are my absolute favorite for this recipe — they have a naturally buttery flavor and a creamy texture that is just perfect here. Russet potatoes also work really well and give you a slightly fluffier interior. I’d steer clear of waxy potatoes like red bliss, as they don’t soak up the cream sauce quite as nicely. Whatever you prefer, just make sure you’re slicing them thin and even!
Can I substitute the Gruyère cheese?
Absolutely! Gruyère gives you that classic nutty, slightly sweet flavor that is just wonderful in a gratin, but I totally understand it can be on the pricier side. Swiss cheese is a fantastic budget-friendly swap and melts beautifully. Sharp white cheddar or even a mild fontina cheese work great too. Use whatever you have on hand — I’m not judging!
Do I need a mandoline to slice the potatoes?
A mandoline makes the job super simple and gives you perfectly uniform slices every time, which helps the stacks cook evenly — so I do highly recommend it if you have one. That said, a sharp knife and a steady hand will absolutely get the job done. Just aim for slices that are about 1/8-inch thick so everything cooks through at the same rate.
How do I store leftovers?
Store any leftover stacks in an airtight container in the refrigerator for up to 4 days. I like to reheat them in the oven or an air fryer at 375°F for about 8–10 minutes to get those crispy edges back. The microwave works in a pinch, but you’ll lose a little of that gorgeous crunch on the outside — still totally worth it though!
Can I add other mix-ins or toppings?
Yes, of course — this recipe is so easy to customize! Crispy bacon bits layered between the potato slices are absolutely amazing. Fresh thyme or rosemary tucked into the cream sauce adds a really wonderful flavor. A little sprinkle of smoked paprika on top before baking gives you gorgeous color and a subtle smoky kick. Feel free to make it your own!
Ingredients Needed: (See Recipe Card Below for the Full Recipe)
- Yukon Gold Potatoes — The star of the show! Their naturally creamy, buttery texture makes them ideal here. Russets work great too if that’s what you have on hand.
- Heavy Cream — This is what gives the gratin that luscious, rich sauce. For a slightly lighter option, you can use half-and-half, though the sauce will be a little thinner.
- Garlic — Freshly minced garlic is a must here — it infuses the entire cream sauce with so much flavor. I use 3 cloves but feel free to add more if you’re a garlic lover!
- Gruyère Cheese — Nutty, melty, and absolutely perfect in a classic gratin. Swiss cheese or sharp white cheddar are great substitutes.
- Parmesan Cheese — Freshly grated Parmesan adds a salty, slightly crispy top to each stack that is just incredible. Pre-grated works, but freshly grated melts so much better.
- Unsalted Butter — Used to grease the muffin tin and add richness to the cream sauce. Salted butter works fine — just ease up on the added salt a little.
- Fresh Thyme — A little fresh thyme goes such a long way here and pairs beautifully with potatoes and cream. Dried thyme works too — use about half the amount.
- Salt and Black Pepper — Season generously! Potatoes need good seasoning at every layer to really sing. Keep tasting your cream sauce until it’s seasoned the way you like.
- Nutmeg — Just a tiny pinch of freshly grated nutmeg in the cream sauce is a classic gratin move that adds the most subtle warmth. Don’t skip it!
How to Make Mini Potato Gratin Stacks
Start by preheating your oven to 375°F and generously buttering every cup of a standard 12-cup muffin tin — and I mean generously! You want these little stacks to release cleanly when they come out, so don’t be shy with the butter. Next, peel your Yukon Gold potatoes and slice them into very thin rounds, about 1/8-inch thick. A mandoline makes this super simple, but a sharp knife works perfectly well too. Set your slices aside while you get the cream sauce going.
In a small saucepan over medium-low heat, combine the heavy cream, minced garlic, fresh thyme leaves, a pinch of nutmeg, salt, and black pepper. You want to heat this gently — stirring occasionally — just until it’s warm and the garlic is fragrant, about 3–4 minutes. Don’t let it come to a full boil. This step is so worth it because that infused cream is what makes every single layer of these stacks taste absolutely amazing. Remove it from the heat and add in about half of the Gruyère, stirring until it melts smoothly into the sauce.
Now comes the fun part — assembling the stacks! Add about a teaspoon of the cream sauce to the bottom of each muffin cup, then start layering your potato slices in, spooning a little cream sauce between every couple of layers and sprinkling in some of the remaining Gruyère as you go. I like to build each stack about 3/4 of the way up the muffin cup — the potatoes will shrink down slightly as they bake. Finish each stack with a final spoonful of cream sauce and a generous pinch of freshly grated Parmesan on top.
Cover the muffin tin tightly with foil and bake at 375°F for 30 minutes. Then remove the foil and continue baking for another 20–25 minutes, until the tops are deeply golden and the potatoes are completely tender when you poke them with a knife. That uncovered time is what gives you those gorgeous, lacy, crispy Parmesan edges that everyone goes absolutely wild for. Let the stacks cool in the pan for at least 5 minutes before carefully running a small offset spatula or butter knife around the edges to release them. Boom — dinner is served!
Pro Tips
- Slice Evenly for Even Cooking — This is probably the most important tip I can give you! Uneven slices mean some potato pieces will be overcooked while others are still underdone. Take your time with the slicing, or use a mandoline set to 1/8-inch for perfectly uniform rounds every single time.
- Don’t Skip the Foil for the First Half of Baking — Covering the pan with foil for the first 30 minutes traps in steam, which is what gently cooks the potato layers all the way through. Removing the foil for the second half gives you that beautiful, golden, crispy top. Both steps are equally important!
- Season Every Layer — Potatoes are thirsty for seasoning, and if you only season the cream sauce and not the layers themselves, the finished stacks can taste a little flat. I like to give each potato layer a tiny extra pinch of salt as I build the stacks for maximum flavor all the way through.
- Let Them Rest Before Unmolding — I know it’s tempting to pop them out of the tin the second the timer goes off, but giving them 5–10 minutes to rest makes such a difference. The cream sauce firms up slightly and the stacks hold their shape so much better when you go to remove them.
- Grate Your Own Cheese — Pre-shredded cheese has anti-caking agents that can make it melt a little unevenly and sometimes turn grainy in a cream sauce. Freshly grated Gruyère and Parmesan melt so smoothly and give you that perfectly creamy, golden finish. It’s a small extra step that is totally worth it.
- Use a Non-Stick or Well-Seasoned Muffin Tin — This makes unmolding so much easier and stress-free! If you’re not sure about your pan, you can also cut small rounds of parchment paper and press them into the bottom of each cup as extra insurance. Future you will be very grateful.
What to Serve with Mini Potato Gratin Stacks
These gorgeous little stacks are such a versatile side dish — they go beautifully with so many different mains, which is a big reason they’re on repeat in my house. Here are some of my favorite things to serve alongside them:
- Roasted Chicken — My personal all-time favorite pairing! A simple herb-roasted chicken with pan juices drizzled over everything is just an absolutely perfect, comforting meal.
- Pan-Seared Steak — These stacks are fancy enough to hold their own next to a beautiful ribeye or sirloin. Such a great steakhouse-at-home dinner!
- Baked Salmon — The richness of the gratin pairs so nicely with flaky, lemon-herb baked salmon. A complete and nutritious meal that feels really special.
- Simple Green Salad — A crisp, lightly dressed arugula or romaine salad is the perfect fresh contrast to the richness of these creamy stacks.
- Steamed or Roasted Green Beans — Quick, easy, nutritious, and the bright green color looks beautiful on the plate next to these golden little stacks.
- Glazed Carrots — A little sweetness from honey-glazed carrots is such a lovely complement to the savory, cheesy potato flavor here.
Whatever you choose to serve these with, I promise your family is going to be very happy at the dinner table tonight — enjoy every bite!
Mini Potato Gratin Stacks
Ingredients
Method
- Preheat your oven to 375°F. Generously butter all 12 cups of a standard muffin tin, making sure to coat the sides and bottoms thoroughly. Set aside.
- Peel and slice the potatoes into 1/8-inch rounds using a mandoline or a sharp knife. Try to keep the slices as uniform as possible for even cooking.
- In a small saucepan over medium-low heat, combine the heavy cream, minced garlic, thyme, nutmeg, salt, and black pepper. Heat gently for 3–4 minutes, stirring occasionally, until warm and fragrant — do not let it boil. Remove from heat and stir in ½ cup of the Gruyère until melted and smooth.
- Spoon about 1 teaspoon of the cream sauce into the bottom of each muffin cup. Begin layering potato slices into each cup, adding a small spoonful of cream sauce and a pinch of the remaining Gruyère every 2–3 layers. Continue building until each cup is filled about ¾ full. Finish with a spoonful of cream sauce and an even sprinkle of Parmesan on top of each stack.
- Cover the muffin tin tightly with aluminum foil and bake for 30 minutes. Remove the foil and continue baking for an additional 20–25 minutes, until the tops are deep golden brown and a knife slides easily through the potatoes with no resistance.
- Remove from the oven and let the stacks rest in the pan for 5–10 minutes. Run a small offset spatula or butter knife around the edges of each cup to loosen, then carefully lift each stack out. Serve immediately and enjoy!
