Easiest Ranch Scalloped Potatoes!
Scalloped Potatoes are as classic as Creamy Mashed Potatoes and Sweet Potato Casserole on our holiday table. This is sure to become your go-to potato bake for Thanksgiving, Christmas, and Easter.
This sliced potato casserole recipe is your secret weapon for an easy, impressive side dish that always gets rave reviews. The potatoes turn out creamy and cheesy, infused with wonderful garlic-ranch flavor.
Ranch Scallopped Potatoes Ingredients
My short list of ingredients will surprise you, but the combination just works. It’s perfect for a busy weeknight but is also creamy, decadent, and worthy of any special occasion.
- Potatoes – we love starchy russets, which soften beautifully
- Ranch, Milk & Mayonnaise – create a flavorful and creamy base that infuses every slice of potato. I love using my homemade ranch or combining a dressing mix with sour cream according to the package instructions, which also works great. If using store-bought dressing, the ones in the refrigerator section are typically better.
- Garlic – we use a generous 3 large cloves which adds great flavor
- Cheese – a medium cheddar cheese adds that salty bite and forms a cheesy crust.
The #1 Tip for Making Ranch Scalloped Potatoes
Slice potatoes thinly and evenly – this is the most important tip for the potato casserole to cook through quickly and evenly.
I used our food processor (using setting #1.5 on our slicing disk attachment). A mandolin slicer would also work well to thinly slice the potatoes and save you time.
How to Make Creamy Ranch Scalloped Potatoes
- Combine the sauce ingredients in a large bowl (reserving 1 cup cheese for the top).
- Thinly slice potatoes and stir them into the sauce until evenly coated. Separate the slices to ensure sauce coats every slice.
- Transfer coated potatoes to the prepared 9×13 casserole dish, sprinkle with remaining cheese, cover tightly with foil.
How Long to Bake Ranch Scalloped Potatoes?
The bake time will vary based on how thick you cut your potatoes. If you slice them thinner, they will bake through faster. Bake covered with foil at 375˚F for 65-75 minutes or until tender when pierced with a knife, then uncover and bake another 5 minutes. For a golden cheesy crust, broil for 2-3 minutes at the end.
FAQ
If you aren’t using the peeled or sliced potatoes right away, you can keep them in a bowl of water to keep them from browning.
Bake as directed but do not broil. Bring to room temperature then cover and refrigerate for 1-2 days. To reheat, bake covered with foil at 350˚F for 30-35 minutes until heated through.
Great news! We have Skinny Scalloped Potatoes with a homemade, easy roux sauce.
What to Serve with Ranch Scalloped Potatoes
Scalloped potatoes pair well with just about any main course. We love it during the holidays with Prime Rib, our juicy Roast Turkey (don’t forget the Cranberry Sauce) or Baked Ham. Since this is such a decadent side dish, we love to pair it with simple veggie sides like:
- Caesar Salad – with a light homemade dressing
- Roasted Brussels Sprouts– a crowd favorite with bacon
- Broccoli Apple Salad – everything about this one is good
- Roasted Asparagus – with lemon and parmesan
Everything about this easy scalloped potatoes recipe is good. This cheesy potato casserole always disappears fast and gets rave reviews.

Just in case anyone has the bright idea like me to try this recipe in the airfryer. Don’t. Took just as long time wise, and it did not cook properly (raw on the inside crispy on the outside) I did make it work eventually but definitely wouldn’t recommend.
That is so good to know that it does NOT work in an air fryer. Thank you for sharing that in case someone else wanted to try it.
Followed the recipe, and then added diced leftover ham. Superdelicious! Will definitely make this colourful dish again.
I’m so happy you enjoyed that. Thank you for sharing that with us, Margareta!
Fabulous recipe
I’m so glad you enjoyed it!
Hi Natasha
Can you suggest a substitute for the ranch dresssing please?
I would love to try this recipe. We all love scalloped potatoes.
Thanks!
Love watching your videos.
Hi Lynn, a homemade ranch, or combining a dressing mix with sour cream according to the package instructions also works great. You can experiment using your favorite ranch dressing.
please can you tell me what ranch dressing is …I am from south africa
Hello Glynis, this is the ranch dressing that I am using.
Did you use the liquid ranch dressing or the dry ranch seasoning? In your response to GLYNIS, with a link, the link showed the dry ranch.
Hi Lix, we used 1/2 cup ranch dressing (we used refrigerated yogurt ranch). You can also use the dry ranch and make it yourself.
I have not had scalloped potatoes in a very long time. I’ve never tried it with ranch before so I’m looking forward to trying this recipe.
I used to put sliced kielbasa in with the potatoes and top with cheese and bread crumbs, and with corn on the side, it was a favorite. I love learning new ways to make old favorites. I cannot wait to try this.
Hi Ericka, I hope you’re going to love this recipe! Please share with us how it goes if you try this out.
This dish is easy and so delicious. I followed the recipe almost exactly, as I used 2% milk instead of whole milk as that is what I had on hand, and it came out great.
I’m so glad you enjoyed it!
Oh my gosh… seriously delicious and so simple. Who would have ever thought of using mayonnaise and ranch salad dressing as a base? Natasha you rock, as usual! I do agree there is a lot of grease but I used some paper towels to remove some of it. A definite keeper in my side dishes.
Hi Cheri, so great to know that you loved this recipe! Thank you for sharing your great feedback with us.
I love many of your recipes, mostly because they are pretty easy to make. I wonder if you can use sliced canned potatoes that are drained, for this recipe? I don’t have the tools for cutting thin slices.
Hi Ingrid, I honestly haven’t tried that yet to advise. I imagine that would work but I can’t say for sure unless I try it. If you do an experiment, please share with us how it goes.
Ingrid, let me know if you tried the canned potatoes. This would be a great idea for the Motorhome on long trips!
These potatoes are delicious. But, they take twice as long to bake than what the recipe says. That being said just plan on bake time to be longer.
Natasha’s recipes are ALWAYS good. I’ve never made anything of hers that isn’t fabulous
Hi Julie, thanks for sharing your suggestion with us. This is the baking time that worked for me, but I appreciate the heads up for others. I’m also glad you are enjoying my recipes! Thank you so much for your good feedback.
Can you substitute the russet potatoes for red potatoes?
Thanks, Pat
Hi Pat, I haven’t tried that substitutions for this recipe specifically, but I bet that could work with a few alterations.
Natasha: I love your recipes. But so many of them don’t have videos when I try and access them from the Facebook posts. Videos are much easier to follow for many of us. Any chance we can get the video attached to the link as well? Thank you.
Thank you so much for that suggestion. Not all of our recipes have videos, but you can find all of our videos HERE.
Hi Natasha
what can I substitute yogurt each with for scallop potato dish
Thank you
Hi Anne, I haven’t tried a yogurt substitute here to advise. If you experiment I would love to know how you like that.
Can you substitute sour cream instead of the ranch dressing and if so would I use the same amount?
Hi Christine, that may work although I haven’t experimented with that. You may need to alter your spices to make up for the ranch flavor.
I put mine in the microwave. 10 min. stir 10 min done. Total 20 min. Make my cream sauce with onion and cheese pour over potato.
I’m going to be trying Green Goddess dressing with Yogurt, Basil and Tarragon.
Can this recipe be done in a slow cooker? Thanks
Hello Jean, I honestly haven’t tried making this in a slow cooker yet to advise. If you do an experiment, please share with us how it goes!
Best potato recipe EVER. I cant even get over how good these are. I did have to soak up a lot of grease from all the sauces and cheese, I dont know, maybe I won’t do that next time. It was still so amazing 👏 😍
I’m so happy to hear that! Thank you for sharing your great review, Holly!
Forgot to give this 5 stars!
Wow! These turned out amazing. They were so easy to make, my 13 year old daughter pretty much made them on her own. They turned out creamy and cheesy, I plan on this being one of my go to side dishes! Thank you!
You’re welcome, Kristy! Thank you for this wonderful review!
These are amazing. I have made scalloped potatoes for many years and I made these for the first time last night. Everyone loved them. My husband says that’s a keeper recipe. Thank you so much!
That’s so great! It sounds like you have a new favorite!
Can this recipe be made in the crockpot?
Hi Angela, I haven’t tested that yet to advise. If you do an experiment, please share with us how it goes.
