After decades of making au gratin potatoes, I’ve perfected the balance of creamy, cheesy goodness in this classic French dish. My secret? Herb-infused cream, Gruyère cheese, and tender layers of potatoes, baked to golden, bubbly perfection. With simple ingredients and easy, step-by-step instructions, you’ll create a flawless dish that’s sure to impress at any holiday or special occasion. Whether you’re cooking for family or a crowd, this naturally gluten-free recipe never fails to wow—even the toughest critics!
The secret to my best-ever au gratin potatoes? It’s all about infusing the cream with herbs, garlic, and spices before layering it with the potatoes. This extra step ensures the rich flavors permeate every bite, turning a simple dish into something truly special. I also use a mandoline to slice the potatoes evenly, which helps them absorb the herb-infused cream perfectly and cook through evenly.
In addition to the herb-infused cream, I like to use a mix of Gruyère and sharp cheddar. While Gruyère gives that classic nutty flavor and smooth melt, the sharp cheddar adds an extra depth that really sets this recipe apart. The result? A cheesy, golden topping that bubbles up beautifully without becoming too oily.
Another key to success is not rushing the baking process. I recommend baking the potatoes low and slow, giving them time to soften and absorb all those infused flavors. And here’s a tip that’s often overlooked: let the dish rest for 10-15 minutes after baking. This allows the sauce to thicken and the flavors to meld, making every bite creamy, flavorful, and irresistible.
Yes, this dish takes a little longer to make, but trust me—it’s so worth it! Taking the extra time to infuse the cream and bake the potatoes slowly might seem like a lot, but the end result is rich, flavorful, and absolutely unforgettable. Once you taste that creamy, cheesy goodness with hints of garlic and herbs in every bite, you’ll see why this recipe is a must for special occasions. After all, some of the best things in life take a little extra time!
I made this recipe for our Easter family gathering! It was amazing. So flavorful and creamy…it didn’t last long!! This is our new go to potato dish for the holidays! You must make this!!!!

What’s the difference between au gratin and scalloped
The primary difference between scalloped potatoes vs au gratin is that scalloped potatoes do not have cheese. Gratin, meaning cheese is a clear distinction in these amazing potatoes. And in this case, it means the King of cheese, gruyere cheese — delicious, nutty, melts beautifully.
Scalloped potatoes typically have flour in them in order to thicken them up, but not these potatoes, the thick cooked cream mixture along with the gruyere cheese does the job! Which also means they are gluten-free au gratin potatoes!

Best au Gratin Potatoes Ingredients
- Heavy Cream | Use the real heavy cream, it’s the holidays, and they deserve all the richness heavy cream brings.
- Whole Milk | The same goes for the milk, but if all you have is a lower fat percentage, then by all means use it! It just won’t be quite as creamy, thick and rich.
- Herbs | We will infuse the milk and cream with fresh herbs, garlic cloves, rosemary and thyme are the best. Fresh is best, but I have used 1 teaspoon of each herb in dried form in a pinch.
- Russet Potatoes | I think russets work and hold up the best, but I have also used Yukon gold, peel these potatoes unless you want a really rustic look.
- Gruyere Cheese | Use a quality gruyere cheese and grate it yourself, to avoid having the extra caking agents often in pre-grated cheeses.
- Butter | Just a touch, to finish off the dish.
- Kosher Salt and White Pepper | You may also use black pepper if desired, it will just show more in the dish!

Best Cheese for Au Gratin Potatoes
For the best au gratin potatoes, I recommend a mix of Gruyère and sharp cheddar. Gruyère melts beautifully, offering a creamy texture and a slightly nutty flavor, while sharp cheddar adds a bold, tangy bite. This combination gives the dish a rich, cheesy topping that complements the creamy potatoes perfectly!
Best Potatoes for au Gratin Potatoes
I prefer using Russet potatoes for au gratin because their higher starch content helps create distinct layers, while still delivering a tender texture. Yukon Golds are another good option, offering a softer and creamier texture, but if you want those beautifully defined layers, Russets are your best bet!
Equipment needed
- Pan | A 9×13 ” pan, I love the Staub casseroles as they clean up beautifully!
- Mandolin Slicer | These really make it so simple to slice paper thin potato slices, you can with a bigger one or this simple hand held.
- Strainer | After you have infused the cream mixture with herbs and garlic, you’ll need to strain it all out.

How to make Potatoes Au Gratin
Step 1 | Prep pan and make infused cream
Grease a 9×13 inch casserole dish (glass or ceramic preferred) with 1 tablespoon butter, set aside. I smoosh the butter in the dish using a paper towel to get it all over.
In a small saucepan, bring milk, cream, garlic, rosemary, thyme, sea salt and pepper to a low simmer. Cook on low for 30 minutes.
Step 2 | Strain and prep potatoes
While cream mixture simmers, peel potatoes (my favorite peeler!) slice the potatoes ⅛ inch thick — if you’ve never used a mandolin slicer give it a try, your slices will be even and uniform and done lickity-split!
Place sliced potatoes in a bowl of cold water until ready to assemble, then drain and pat dry, if a short period of time you can forgo this step, if longer, they will brown quickly.
Strain out herbs and garlic into a bowl, discarding the herbs and garlic. Reserve infused cream mixture.
Step 3 | Assemble potatoes au gratin Ina Garten style
Arrange potatoes in rows, overlapping slightly, seasoning each layer with sea salt and white pepper.
Sprinkle a handful of Gruyere cheese over potatoes and pour ½ cup cream mixture over the potatoes.
Repeat steps twice, finish by pouring remaining cream mixture over the top.
Dot with 1 tablespoon butter; cover with foil and bake.
Step 4 | How to Bake Au Gratin Potatoes
Bake in preheated 375°F (190° C) oven for 45 minutes; then remove foil and continue baking, uncovered for an additional 45 minutes, until golden brown and bubbly and potatoes are fork tender (insert fork into potatoes, they should yield to gentle pressure.)
Can I make Potatoes Dauphinoise ahead of time?
Please make and bake these au gratin potatoes ahead and save yourself some precious time on your holiday.
- Bake gluten free au gratin potatoes a total of 60 minutes undercooking potatoes slightly, they should be a light brown instead of a deep golden brown.
- Once cooled, cover with a sheet of wax paper pressed into the potatoes (protect against freezer burn), then cover with foil, sealing baking dish well.
- If serving within 24-48 hours, refrigerate until ready to reheat. Or freeze-wrapped in plastic wrap, then again in foil up to 2 weeks.
- For best texture and flavor, thaw in refrigerator overnight or bake from frozen (might require a bit more time).
Fresh Tip
- While you may prep the dish and refrigerate baking the next day, your potatoes will turn a purple-brown. The color is a bit off-putting, but it won’t hurt you. So I recommend baking them ahead, cooling and warming on serving day.
Au Gratin Potato Recipe Variations & Substitutions
- Cheese Variations:
- Experiment with different cheeses. Instead of the traditional Gruyère or Emmental, try cheddar, Parmesan, or Gouda for a unique flavor.
- You can also combine multiple cheeses for a more complex taste.
- Vegetarian or Vegan Version:
- Substitute dairy cream with a non-dairy alternative like coconut cream or almond milk for a vegan version.
- Use vegan cheese or nutritional yeast for a cheesy flavor in the absence of traditional dairy cheese.
- Sage | If you enjoy the flavor of sage, add a leaf or two to your cream herb infusion.
Storage Tips
Store cooled leftovers in an airtight container in the fridge for up to 5 days.
Can You Freeze Au Gratin Potatoes?
Yes, you can freeze au gratin potatoes! To freeze, allow the dish to cool completely, then wrap it tightly in plastic wrap and a layer of aluminum foil. You can freeze them up to 2 weeks ahead of time. When you’re ready to serve, you can either thaw the potatoes in the fridge overnight or bake them directly from frozen. If baking from frozen, remove the plastic wrap, then recover the dish with foil and bake at 350°F (175° C) for about 60-75 minutes, removing the foil for the last 20 minutes to let the top get golden and bubbly. Keep in mind, the texture may soften slightly after freezing, but the flavors will still be delicious!
How to reheat Potatoes Dauphinoise
- Place potatoes Dauphinoise in preheated 375° F (190° C) oven, covered with aluminum foil for about 30-40 minutes, removing foil last 10 minutes to brown. Should be bubbly around edges and warmed in center with a deep golden brown hue.
- To determine if warmed through, stick butter knife in middle of gratin holding for about 30 seconds. Remove knife, if warm or hot to touch, they are warmed through, if cool to touch, return to oven in 15 minute increments, covering with foil if browning too quickly.
- Or place on microwave safe dish and warm in 30-45 second bursts until warmed through.
Potatoes au Gratin Recipe FAQs
Sometimes we cannot get our hands on fresh herbs! I have been asked is it okay to substitute dried herbs for fresh herbs and the answer is YES!
HERB SUBSTITUTION RULE | Use ⅓ the amount of fresh in the recipe.
For instance: Instead of a tablespoon (3 teaspoons) of fresh rosemary, you would add 1 teaspoon of dried rosemary and thyme, etc.
A potato dish cooked in a cream, milk and cheese mixture.
While many people believe that the word gratin means cheese, the word gratin is actually derived from the French word grater or gratter, meaning to grate. One would assume that gratin then refers to grated cheese, however, often times it also meant breadcrumbs and or cheese that is browned and crisped. (Source)
Yes, without any changes! Unless you are using pre-shredded cheese (watch those ingredients), this is a completely vegetarian and gluten free potato holiday side dish.

Made for Easter 2025. Rave reviews / I was told they were the best scalloped potatoes they ever had. I made 5 pounds, added 3/4 c extra milk and extra cheese. They really were delicious!
Oooo, sounds amazing Cheri! Thank you for your sweet comment! Happy Easter Monday!
Alli
Love these! They are delicious
Makes me so happy, Alli!
Bess Gordon
I hardly ever write a review but this was sooooo delish! I had some leeks so I sautéed those for a layer and they were crazy good. I baked covered for 45 minutes, took out, went to an event, came home and finished cooking it is such a keeper!
Thanks for making my day Bess!! So glad you loved it!
Julie D
Awesome recipe. I baked this in a huge cast iron skillet and talk about delish! I didn’t have the Gruyère cheese the first time I made it. But, I’m about to make it again with the Gruyère. My entire family loved it and devoured it quickly!
Thanks so much Julie! So glad you all loved it!
