Side Dishes
Here’s the Barefoot Contessa potato gratin recipe that delivers the creamy, crispy perfection Ina Garten makes famous in her kitchen. The secret lies in thinly sliced potatoes layered with Gruyère cheese and a vinegar-kissed béchamel that creates an irresistibly crisp top while keeping the inside velvety.
After perfecting this technique over years of testing, I can confidently say this is the closest you’ll get to her restaurant-quality results at home.
The method is simpler than it looks—no fancy equipment, just precise layering and patience. Thinly sliced potatoes prevent uneven cooking, while the béchamel (made with butter, flour, and a splash of vinegar) adds depth and that signature crispness.
Gruyère cheese melts into a luscious, golden blanket, and fresh thyme infuses every layer with aromatic warmth. The result? A dish so elegant it belongs on any dinner table, yet approachable enough for weeknight meals.
What makes this gratin truly special is the contrast: a shatteringly crisp top that gives way to tender, melt-in-your-mouth potato layers beneath. The vinegar in the sauce cuts through the richness, balancing flavors perfectly, while the Gruyère adds a nutty, slightly sweet finish.
This isn’t just a side dish—it’s a centerpiece that transforms ordinary meals into something extraordinary. Let’s get started on creating your own restaurant-worthy gratin.
Once baked to golden perfection, this gratin pairs beautifully with roasted meats, fresh salads, or even as a standalone dish. Garnish with extra thyme or a sprinkle of flaky sea salt for a final touch that elevates it further.
The key to success? Don’t rush the layers—each one matters for that textural harmony that defines a great gratin. Trust the process, and you’ll have a dish that tastes like it came straight from the Barefoot Contessa’s kitchen.
Ingredients for barefoot contessa potato gratin
Thinly sliced potatoes, Gruyère cheese, and a vinegar-kissed béchamel create this restaurant-worthy gratin.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Thinly sliced (1/8-inch thick) |
| Gruyère Cheese 🧀 | 2 cups | Freshly grated, block preferred |
| Heavy Cream 🥛 | 1 ½ cups | Full-fat for creaminess |
| Whole Milk 🥛 | ½ cup | Warmed slightly for sauce |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for béchamel |
| All-Purpose Flour 🌾 | ½ cup | Sifted for smooth sauce |
| White Wine Vinegar 🍶 | 1 tbsp | For tangy balance |
| Fresh Thyme Leaves 🌿 | ½ cup | Chopped, stems removed |
| Garlic Cloves 🧄 | 4 cloves | Minced for béchamel |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Nutmeg 🌶️ | ¼ tsp | Freshly grated |
| Flaky Sea Salt 🧂 | ¼ cup | For garnish |
The Gruyère cheese is non-negotiable here—it melts into that signature nutty, velvety blanket. Whole Foods or specialty cheese shops carry the best blocks, but skip the pre-grated stuff (it gets clumpy). For the potatoes, Russet is your best bet—thinly sliced (1/8-inch thick) ensures even cooking. I use a mandoline for perfect slices, but a sharp knife works too if you take your time. The thyme should be fresh (the good stuff, not the dried kind)—it infuses every layer with that aromatic warmth. If you're short on time, dried thyme at half the amount works in a pinch, but fresh is worth the extra minute.
No white wine vinegar? Apple cider vinegar does the trick, though the flavor profile shifts slightly. The béchamel is where the magic happens—the vinegar and nutmeg balance the richness, while the butter and flour create that signature crisp top. If you're making this ahead, prep the béchamel separately and reheat gently before layering. For the Gruyère, if you can't find it, Comté or Emmental work as substitutes, though the flavor won't be identical. And trust me on the full-fat cream—low-fat versions won't give you that luscious texture.
This gratin tastes even better the next day—honestly, it's worth making a day ahead. Store leftovers covered in the fridge for up to 4 days, though I rarely have any left that long. To reheat, cover with foil and warm at 350°F for 20 minutes. The crisp top softens slightly, but it's still delicious. For serving, a sprinkle of flaky sea salt and extra thyme takes it from weeknight dinner to restaurant-worthy. And if you're feeling fancy, pair it with a dry white wine—the acidity cuts through the richness perfectly.

Step-by-step instructions for Barefoot Contessa potato gratin
This method delivers restaurant-quality layers with a vinegar-kissed crisp you'll crave every time.
Prepare the Potatoes for Perfect Layers
Peel the 3 lb russet potatoes and slice them into 1/8-inch thick rounds using a mandoline or sharp knife. I like to keep them consistent in size so they cook evenly. As you slice, soak the potatoes in cold water for 10 minutes to remove excess starch—this prevents a gummy texture later. Drain well before using.
Arrange the sliced potatoes in a single layer on a baking sheet lined with paper towels. Sprinkle lightly with 1/2 teaspoon of salt and let them sit uncovered for 15 minutes. This step draws out moisture, ensuring crispy edges when baked. You'll notice the slices start to dry slightly at the edges—that's exactly what we want.
Make the Vinegar-Kissed Béchamel Sauce
In a medium saucepan, melt the 1/2 cup unsalted butter over medium heat. Once melted, whisk in the 1/2 cup all-purpose flour and cook for 2 minutes until the mixture turns golden and smells nutty. This is called a roux, and it's the foundation of our creamy sauce.
Gradually whisk in the 1.5 cups heavy cream and 1/2 cup whole milk until smooth. Add the 1 tablespoon white wine vinegar, 1/2 teaspoon black pepper, 1/4 teaspoon nutmeg, and 1 teaspoon salt. Bring to a gentle simmer and cook for 5-7 minutes until the sauce thickens enough to coat the back of a spoon. It should be smooth and glossy—this ensures our gratin stays creamy without being watery.
Assemble the Gratin with Precision
Preheat your oven to 375°F. Lightly grease a 9x13-inch baking dish with butter to prevent sticking. Start by layering 1/3 of the potato slices in a single layer at the bottom of the dish. Sprinkle with 1/3 of the chopped fresh thyme leaves and 1/3 of the minced garlic cloves. Pour 1/3 of the béchamel sauce over the potatoes, making sure each slice is coated.
Repeat this layering process twice more, ending with a final layer of potatoes. The top layer should be covered with the remaining béchamel sauce. Sprinkle the 2 cups freshly grated Gruyère cheese evenly over the top, pressing it lightly into the sauce. This ensures maximum meltiness when baked.
Bake Until Golden and Bubbly
Cover the baking dish tightly with heavy-duty aluminum foil and bake for 45 minutes. This initial covered baking helps the potatoes soften without browning. After 45 minutes, remove the foil and increase the oven temperature to 400°F. Bake uncovered for another 20-25 minutes until the top is deep golden brown and bubbly.
Here's the key: the edges should be crispy while the center remains tender. You'll know it's done when a knife slides in easily but the potatoes still have a slight resistance. The vinegar in the sauce creates that signature crispy crust that sets this gratin apart.
Rest, Garnish, and Serve
Remove the gratin from the oven and let it rest for 10 minutes before serving. This resting period allows the layers to set slightly, making it easier to slice. While it rests, sprinkle the top with 1/4 cup flaky sea salt for that final touch of luxury.
Slice into squares and serve immediately with a crisp green salad or roasted vegetables. The contrast of the cool salad with the warm, creamy gratin makes every bite perfect. Leftovers can be refrigerated for up to 3 days, but I promise you won't have any—this dish disappears fast!
Pro Tips For Making Barefoot Contessa Potato Gratin
- PRE-COOK POTATOES: I learned this the hard way—parboiling the Russets for 8 minutes first cuts the baking time by nearly half and keeps them from turning to glue. Just don’t overdo it; they should still hold shape when pierced with a fork.
- GRATE GRUYÈRE FRESH: Pre-shredded cheese is convenient, but it packs down and loses moisture. Using a box grater right before layering keeps the Gruyère fluffy and melty—no clumping, no sad texture. (Yes, it’s extra work, but the difference is noticeable.)
- LOW AND SLOW CRUST: The Barefoot Contessa method relies on a gentle oven—275°F isn’t a typo. If you crank it up, the top burns before the center cooks. Cover with foil for the first 45 minutes, then uncover to brown; patience here makes all the difference.
- SALT THE CREAM: The cream mixture needs salt—more than you’d think, especially if your Gruyère is mild. A pinch per cup of heavy cream and milk balances the dish and prevents blandness. (I used to skip this and wondered why my gratin tasted flat.)
Essential equipment for perfect results
Mandoline Slicer
For perfectly even 1/8-inch potato slices, a mandoline slicer is a game-changer. I swear by the OXO Good Grips model—it’s affordable, safe, and delivers razor-sharp slices every time. The thin slices cook uniformly, preventing gummy centers.
If you don’t own one, a sharp knife works, but it takes patience and steady hands. Just be careful—those slices are slippery! 🔪
Heavy-Duty Baking Dish
A 9x13-inch baking dish with deep sides is essential for this gratin. I recommend All-Clad Stainless Steel or Le Creuset Stoneware—both distribute heat evenly and handle high temperatures without warping.
Avoid thin, flimsy dishes that can’t withstand the 400°F finish. If you’re prepping ahead, these materials also reheat beautifully. Pro tip: Grease it lightly with butter to prevent sticking.
High-Quality Cheese Grater
Freshly grated Gruyère cheese makes all the difference. Skip the pre-shredded stuff—it’s full of anti-caking agents that make the gratin grainy. A microplane or box grater (like the OXO Good Grips version) gives you the finest, most flavorful shreds.
For extra efficiency, grate the cheese directly over the baking dish to minimize mess. 🧀
Thermometer for Precision
While gratin doesn’t require a thermometer like meats, an oven thermometer ensures your oven is actually at 375°F and 400°F. Many home ovens run hot or cold, and accurate temperature control is key for that signature crispy top.
I use the Thermoworks Oven Thermometer—it’s reliable and affordable. Trust me, a few degrees can make or break your gratin’s texture.
Butter Knife for Garnishing
A butter knife isn’t just for spreading—it’s perfect for sprinkling flaky sea salt and fresh thyme evenly over the finished gratin. The wide, flat blade distributes garnishes smoothly without tearing the crispy top.
I also use mine to press the Gruyère into the sauce before baking, ensuring maximum meltiness. Keep one handy for those final touches! ✨
Aluminum Foil (Heavy-Duty)
Don’t skimp on the foil—heavy-duty aluminum foil is a must for covering the gratin during the initial 45 minutes of baking. Regular foil tears or doesn’t seal tightly enough, letting steam escape and ruining the texture.
I use Reynolds Wrap Heavy Duty, which stays put even when the dish shifts in the oven. Crimp the edges tightly to trap moisture and steam for that creamy interior.

Frequently asked questions
Why does the Barefoot Contessa gratin recipe use vinegar in the sauce?
The 1 tablespoon white wine vinegar in the béchamel serves two critical purposes: it balances the richness of the cheese and cream, and it creates that signature crispy top when baked. The acidity also helps tenderize the potatoes slightly, ensuring a perfect texture throughout. Without it, the gratin would taste flat and lack that signature Barefoot Contessa touch.
Can I substitute Gruyère cheese with something else?
While Gruyère is ideal for its nutty, slightly sweet flavor, you can use Comté or Emmental in a pinch. Avoid pre-shredded cheese—it contains anti-caking agents that make the gratin grainy. For a dairy-free option, try a mix of sharp cheddar and nutritional yeast, though the texture won’t be identical. The key is a cheese that melts smoothly and adds depth to the dish.
How do I fix a gratin that’s too watery or not crispy enough?
If your gratin is watery, it likely didn’t bake long enough. Increase the uncovered baking time by 10-15 minutes at 400°F until the top is deeply golden. For a crispier top next time, ensure your oven reaches 400°F (use an oven thermometer) and broil for 2-3 minutes at the very end. The vinegar in the sauce also plays a key role—don’t skip it!
Can I make this gratin ahead of time?
This gratin tastes even better the next day. Assemble it completely, cover tightly with foil, and refrigerate for up to 24 hours before baking. When ready to bake, add 10-15 minutes to the covered baking time (since it starts cold). For leftovers, reheat covered at 350°F for 20 minutes—the crisp top softens slightly but remains delicious.
What’s the best way to slice the potatoes for even cooking?
Use a mandoline slicer for perfectly even 1/8-inch thick slices—this ensures all pieces cook at the same rate. If you don’t have one, a sharp knife works, but take your time for consistency. Soak the sliced potatoes in cold water for 10 minutes to remove excess starch, then pat them dry before layering. This step prevents a gummy texture and promotes crispy edges.
