It’s just that good. These scalloped potatoes are lower in fat than our original scalloped potatoes but still taste incredibly indulgent and are loaded with flavor.

Ingredients for Skinny Scalloped Potatoes:

3 lbs Yukon Gold Potatoes, peeled
4 Tbsp unsalted butter
1/2 large or 1 medium yellow onion, finely diced
2 large or 3 medium garlic cloves
2 Tbsp all-purpose flour
1/2 Tbsp sea salt
1/2 tsp black pepper
3/4 cup parmesan cheese (divided into 1/4 cup for center, 1/2 cup for topping)
1 1/2 cups milk (any kind)
1 cup low sodium chicken broth
Green onions to garnish, optional

How to Make Scalloped Potato Gratin Recipe:

1. Butter the bottom and sides of a 9×13 casserole dish.

2. Using a mandolin, thinly slice potatoes into rounds about 1/8″ thick. Place potato slices in a bowl with cold water while you prep the sauce. This keeps them from discoloring and removes some of the starch. Drain potatoes well, just before you put them in your casserole dish.

How to make Skinnier Scalloped Potatoes:

Preheat Oven to 400˚F.

1. In a medium sauce pan over medium/high heat, melt 4 Tbsp butter. Add finely diced yellow onion and saute until soft and golden (5 min). Add pressed garlic cloves and saute another 1-2 min, stirring constantly, until fragrant. Whisk in 2 Tbsp flour and cook another 1 min until flour is golden. Add 1 1/2 cups milk and 1 cups chicken broth. Whisk mixture until smooth and bring to a simmer. Stir in 1/2 Tbsp sea salt and 1/2 tsp pepper (or season to taste). Remove from heat.

2. Drain potatoes and arrange half of them in the bottom of your casserole dish (it doesn’t matter how the first layer is arranged, just separate the potato slices as you put them in). Pour half of your sauce over the top and sprinkle with 1/4 cup parmesan cheese. Repeat with remaining potatoes, sauce and top with 1/4 cup parmesan cheese. I made the second layer of potatoes prettier for presentation.

3. Cover with aluminum foil and Bake in the center of the oven at 400˚F for 55 minutes then uncover and broil another 3-5 minutes or until the top is golden brown. Garnish with green onion if desired and serve. Look at all that creamy (reduced fat) goodness!

    Hi Natasha, recipe looks great – planning to try for Easter tonight. I have read though that the starch from the potatoes can help thicken the sauce (I figure definitely helpful for a low-fat i.e. no cream) recipe. Do you have any thoughts, in that case, if not soaking the potatoes? Thanks! Kelly

      Hi Kelly, this is the best I have been able to come up with to keep it creamy while still staying creamy. If you experiment, let me know how it goes.

    I’ve made this so many times already! And twice within this week, both times for company, and no leftovers both times! We don’t really like parmesan, so I just replace with mozzarella, absolutely delicious!! By the way, my husband does not like potatoes in almost any form, and if I make potatoes, they must be accompanied with something else that will give a different flavor. This dish though, he can never get enough of, and is surprised that it’s mostly just potatoes!;)) thank you so much for this amazing recipe!!

      Hi Bridget, I haven’t tried this in a crockpot so I can’t really guess. I would suggest searching out some scalloped potato recipes online for ideas on the method. Sorry I can’t be more helpful! Maybe someone else has tried? Thanks in advance! 🙂

    The first time I made this my husband couldn’t stop complimenting how good it was. Even my 4 year old said, “mom you make really good food.” I’ve made it numerous times since and its always just as popular. My husband is definitely a meat eater so I always add a layer of cooked, crispy bacon in the middle and it becomes a full meal. Amazing served with a salad on the side. Thank you for a simple, delicious recipe!!

      Came back to review the recipe again because it’s that good 😁 I have been making this regularly for 8 years now, at least a couple times per month. The 4 year old who loved it 8 years ago still loves it now as a 12 year old. I double it for my family of 10 and it’s gone within a day or 2. We personally love it with a side of good pickles. Thank you again Natasha! It’s a gem of a recipe for a large family

      I have not tested it with russet potatoes because I like the flavor and texture of the Yukon’s in this, but I think you could make it work. I hope you love it!

    I’ve got mine in the oven now! To make it even skinnier I’ve used slightly less potatoes for only 1 layer and replaced the second layer with mushrooms. I’ll let you know how it turns out!

      I haven’t tried doing it that way overnight and the only thing I’d be concerned about is browning of the top potatoes that aren’t submerged in the liquid sauce. You could probably prep the ingredients the night before (slice potatoes and put them in cold water in the fridge and make the sauce in a separate bowl and then combine them the day your cooking the casserole).

    Parmesan cheese is so delicious but I have a bad eating habit probably because I’m a Mediterranean woman: I mix parmesan with pasta and nothing else, never.
    I’ve not baked your gratin yet but have experimented simple boiled potatoes with parmesan and it’s genius !

    I’m so excited to make this, looks delicious! Scalloped potatoes are a favorite, but I generally default to cauliflower in place of potatoes for the health factor. Look forward to trying the skinny version, thanks for sharing! And congrats on your pregnancy!

      Oh thank you so much for asking! Sorry I missed that. During the testing stage, I tried it once with that combo and I liked the 1 1/2 cups milk with 1 cup broth better. It will still turn out fine the other way, but it’s better with more milk and less broth. I’ve updated the recipe. Thanks again!! 🙂

    My husband is from ukraine and is obsessed with potatoes 😀 I’ll have to try this dish again this time I think instead of buttering the casserole dish I’ll use coconut oil. That will make it even “skinnier” & shouldn’t effect the flavor 🙂 plus coconut oil has tremendous pregnancy benefits (I’m 4.5 months) and I’ve been searching for recipes to use it in.

    Will report back soon and tell you if it tastes the same made both ways 🙂
