Potatoes au Gratin vs Scalloped Potatoes
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!

Simple Ingredients for Potatoes au gratin
- 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!

How to Make Potatoes Dauphinoise
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.
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.)
Recommended Tools
- 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.
Frequently Asked Questions
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)
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-brow. The color is a put off-putting, but it won’t hurt you. So I recommend baking them ahead, cooling and warming on serving day.
Storage Tips
Store cooled leftovers in an airtight container in the fridge for up to 5 days or may be frozen up to 2 weeks.
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.
Are Potatoes Dauphinoise Gluten-Free?
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.
Variations and 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.

Instructions
Prepping Potato Gratin
- Grease a 9x13x2 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 schmear evenly.
- Bring milk, cream, garlic, rosemary, thyme, salt and pepper to a low simmer. Cooking on low for 30 minutes. Strain out herbs and garlic into a bowl, discarding the herbs and garlic. Reserve infused cream mixture.

Assembling & Baking Potato Gratin
- Arrange potatoes in rows, overlapping slightly; seasoning each layer with sea salt and pepper. Sprinkle a handful of Gruyere cheese over potatoes and pour ½ cup cream mixture over the potatoes. Repeat steps twice, finish by pouring on an remaining cream mixture. Dot with 1 tablespoon butter; cover with foil and bake.
- 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).

Notes
- Bake gratin for a total of about 60 minutes undercooking potatoes slightly, remove from oven and cool quickly by placing in refrigerator (be careful and place a hot pad or trivet on your fridge shelf. Remove them when they have a light brown color instead of a deep golden brown hue.
- Once cooled, cover with a sheet of wax paper pressed into the potatoes (protect against freezer burn), then cover with foil and seal baking dish well.
- If serving within 24-48 hours, refrigerate until ready to reheat. Or freeze up to 2 weeks for best texture and flavor, thaw in refrigerator overnight or bake from frozen (might require a bit more time).
- Place in preheated 375°F oven (remove wax paper), covered for about 30-40 minutes, removing foil last 10 minutes to brown. It should be bubbly around the edges and warmed in the center with a deep golden brown hue.
- To determine if warmed through, stick a butter knife in the middle of the 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.
- While you can prepare the dish and not bake, the potatoes will oxidize and turn a purple-brown color, while this will not harm you, the color isn’t pretty, so instead bake and rewarm the day of serving.
Nutrition
If I was to par-cook the potatoes two days in advance (and then place in the fridge)…your instructions show to undercook for 60 min only, cool and then place in the fridge. How much of the 60 min would you cover vs uncover in the oven?
Hi Steph, I would keep them covered for the same amount of time as if you were cooking the whole time. Only cook for 60 total minutes. Make sure you cool them completely before refrigerating. Hopefully that makes sense.
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!!!!
YAY! Thank you so much, Susan!
This sounds delicious! Can this recipe be doubled? I am having about 20 people for Easter dinner
You sure can!! you might need to bake them a little longer if you do it all in one big pan or just split it between two pans
I saw your instructions for baking it ahead of time and refrigerating. But do you think I could just assemble them and put in the fridge and then bake the next day?
Hi Heather, I have never done that. Potatoes tend to turn funny colors when they’re exposed to the air but I would say if you make sure they’re well in the cream sauce and press some plastic wrap on top of it. It should be fine. Just make sure you bring it out about 30 minutes before you’re going to bake it so the shock to the casserole dish doesn’t break when it hits the heat of the oven. Let me know how it turns out!
Ok awesome! That’s what I was thinking based on other similar dishes I’ve made. Thanks for the quick reply!
You are welcome! Hope you love it! I might try the same this year too!
Maybe I’m being dumb. Use 1/2 of the cream mixture and then repeat for 2 more layers? So use none on the second layer and only cheese and the rest on the top OR split the remaining 1/2?
Split the remaining half, sounds like I need to clarify that a bit better! Sorry about that!!
This recipe looks amazing, but I have a quick question. I’m making scalloped potatoes to go with our prime rib on Christmas, but the night before we are having fondue with gruyere. Do you think a different cheese would be good in this recipe, or have you tried another? I feel like it might be too much gruyere for one weekend…but is there such a thing?
As far as I am concerned, you can never have too much, Gruyere 😂. However, a sharp cheddar or Swiss (Emmentaler) would also be really good! Hope you love them!
I have not tried this recipe, but it sounds amazing! I was wondering if I can make the infused cream, and thicken it with corn starch (as it is gluten free), then assemble the casserole?
Hi Gaye — actually my recipe is Gluten-Free, naturally! I use the slow simmer of the cream and then the cheese to thicken it! I hope you enjoy it, it’s quite amazing!
I made a similar recipe recently but this looks much better. The other had no flour in it either and my potatoes were still floating in the cream mixture. How do you get it to thicken without the addition of flour.?
Hi Rhonda, this is an amazing recipe, I believe it’s a combination of simmering down the milk, cream mixture, using a starchier potato such as russets along with the cheese that helps it bubble and thicken. Sometimes if I do not put in quite enough potatoes mine will be “swimming” in the cream mixture a bit more too, but not typically, plus as it sits it firms up well! Hope that helps!
So excited to make these for our Easter dinner! My mouth is watering already.
If fresh rosemary and thyme are not available what would you recommend for plan B?
Great question, Joanne! Generally speaking you swap ⅓ dried herbs for fresh. If a recipe calls for 1 tablespoon fresh rosemary or thyme, then add 1 teaspoon dried rosemary/thyme. And I have made it with dried herbs, I will update my recipe! Happy Easter!
I could eat these all right up! So so good!
These look wonderful!!
Thank you so much Julie, they are dreamy!! LOL!
We tried these potatoes and they are amazing! The way you infused the herbs made such a big difference and the cheese was definitely the hero in this dish. This is my new go-to for potato gratin!
super easy to make and very tasty! Thanks
Made these tonight — boy were they really THE BEST ever!!
Thank you Michaela!! So excited you loved them!
Love the cheesy goodness in this side. Can this be made ahead?
