Let's take a break from all the Christmas cookies and candies and turn our attention towards something savory. Life is all about balance, after all.
Don't get me wrong, I LOVE holiday baking. It's hard to get me to put down my whisk and step away from the oven. But holidays bring so many flavors of fall harvest. There's stuffed acorn squash, vegan mushroom meatloaf, and of course, roasted Brussels sprouts. Too many delicious flavors we simply can't miss out on.
And so, I'm stepping away from my whisk and bringing you a classic holiday side dish with a healthy spin.
It's skinny scalloped potatoes, friends!

This vegan scalloped potato recipe is easy to make and can be done in about 50 minutes. It's the perfect side dish for your holiday meals and Sunday dinners.
Ingredients & Substitutions
- Russet Potatoes
- Yellow Onion
- Garlic
- Olive Oil
- Cheesy Cauliflower Alfredo Sauce - This recipe is a combination of onions, garlic, cauliflower, vegetable broth, vegan parmesan, and spices. It's a healthy twist on Alfredo sauce while still being creamy and decadent. If you would rather use store bought vegan Alfredo sauce (<<affiliate link) feel free to do so.
- Fresh Chives
- Vegan Parmesan - I recommend Violife parmesan. It is creamy, melty, and tastes exactly how I remember parmesan to taste. If you don’t have access to Violife, you can make your own parmesan.
Recommended Equipment
First of all, I recommend a MandolineI love my mandoline! The mandoline allows you to make thin, uniform slices of any fruits and vegetables and while it’s not something I use often, for recipes like this, I am so glad I have one.
You will also need a sauté pan, a blender, basic kitchen utensils, and a 7×11 baking dish (<<affiliate links).

How to Make Vegan Scalloped Potatoes
Step One – Make the Alfredo Sauce
To make the cauliflower Alfredo sauce, heat oil in a large pot over medium-high heat. Once hot, add onions and garlic. Cook, stirring occasionally, until onions are translucent, about 5 minutes. Add cauliflower florets and sauté for another 2-3 minutes. Once slightly tender, add vegetable broth, cover, and cook until cauliflower is soft all the way through, about 5 more minutes.
Transfer to a high-speed blender and add remaining Alfredo Sauce ingredients. Blend until completely smooth.
Pro Tip: This recipe calls for ½ a batch of creamy cauliflower sauce. Consider making a whole batch and store the extra in the freezer for up to 2 months. This makes the perfect skinny alfredo sauce for a quick and easy meal.
Step Two – Prepare the Potatoes and Onions
While the cauliflower cooks, prepare the potatoes. Peel and slice the potatoes into thin slices (about ⅛" thick) and set aside. For the best results, I recommend using a mandoline slicer.
Sauté the onion and garlic in olive oil over medium heat until the onions are sweet and translucent; this takes about 5 minutes. Remove from heat and set aside.
Step Three – Assemble and Bake
Assemble the skinny scalloped potatoes by placing half of the potatoes on the bottom of a casserole dish. Top with half of the creamy cauliflower sauce. Spread the onions in a single layer. Then top with the remaining potatoes and sauce.
Bake for 20 minutes until the potatoes are tender and the sauce is boiling up.
Serving and Storing
Serve these potatoes with vegan parmesan cheese, freshly ground pepper, and fresh chives. Serve as part of your holiday meal or with homemade vegan soup.
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover with tin foil and gently reheat in the oven at 350F.

What Makes These Scalloped Potatoes Skinny?
These potatoes are made rich and creamy from one of my favorite vegetables – cauliflower! The cauliflower cheese sauce is soy-free, not nearly as heavy and rich as a dairy, coconut, or cashew-based one, and is chock-full of good things like Vitamin C, B6, Vitamin K, and Protein.

Laura M says
The taste is delicious but the cooking time didn’t work for me and I gave it longer than suggested. I cooked it covered for 35 mins and uncovered for 30 and we had to put it back in the oven, covered, with more stock poured over to give it some moisture to cook the potatoes.

Am I missing something? Can't see the other cheesy sauce ingredients in the ingredient list to make it cheesey? Nutritional yeast? Cashews?
