Finding a comforting side dish that satisfies everyone at the dinner table—and happens to be plant-based—can feel like an impossible task. Traditional scalloped potatoes are loaded with heavy cream and cheese, which means they’re off the table if you’re cooking for dairy-free guests or just trying to lighten things up a bit on weeknights.
That’s where these scalloped hashbrown potatoes come in. They deliver all the creamy, cheesy goodness you crave from the classic version, but they’re completely dairy-free thanks to a rich sauce made with nutritional yeast and tahini. Plus, using frozen hashbrowns means you can skip the tedious peeling and slicing, making this dish way easier to throw together on busy evenings.
Why You’ll Love These Scalloped Hashbrown Potatoes
- Completely plant-based – This recipe uses nutritional yeast, tahini, and soymilk to create a creamy, cheesy sauce without any dairy, making it perfect for vegans or anyone avoiding animal products.
- Ready in under an hour – You can have this comforting side dish on the table in 45-60 minutes, making it doable for weeknight dinners or last-minute gatherings.
- Simple pantry ingredients – Most of these items are common staples in a plant-based kitchen, so you probably already have them on hand.
- Crowd-pleasing comfort food – The creamy, cheesy flavor and crispy top make this dish so satisfying that even non-vegans won’t miss the dairy.
What Kind of Hash Brown Potatoes Should I Use?
You’ve got a few options when it comes to hash browns for this recipe, and they’ll all work just fine. The most convenient choice is frozen shredded hash browns – just grab a bag from the freezer section and you’re good to go, no need to thaw them first. If you prefer fresh, you can absolutely shred your own potatoes using a box grater or food processor, though you’ll want to squeeze out any excess moisture with a clean kitchen towel before using them. Some stores also sell refrigerated fresh hash browns in the produce section, which are another great option if you want to skip the shredding but prefer fresh over frozen.
Options for Substitutions
This vegan-friendly dish has some room for swaps if you need to work with what you’ve got:
- Hash brown potatoes: You can use fresh potatoes instead – just peel and shred them yourself, then rinse in cold water and pat dry before using. Frozen shredded potatoes work too if you thaw and drain them first.
- Soymilk: Any unsweetened plant-based milk works here – almond, oat, or cashew milk are all good options. Just make sure it’s unflavored and unsweetened.
- Nutritional yeast: This ingredient is really important for that cheesy flavor in this vegan recipe, so I’d recommend not substituting it if possible. If you must, you could try adding a bit more miso and some ground cashews, but the flavor won’t be quite the same.
- Tahini: Cashew butter or almond butter can step in for tahini. You could also use a couple tablespoons of blended raw cashews if that’s what you have on hand.
- Miso: If you don’t have miso, add an extra 1/2 teaspoon of salt and a splash of soy sauce or tamari for that savory depth.
- Cornstarch: Arrowroot powder works as a one-to-one swap for cornstarch. You could also use flour, but you’ll need about 4-5 tablespoons instead.
Watch Out for These Mistakes While Baking
The biggest mistake with scalloped hashbrown potatoes is not spreading the hash browns evenly in the baking dish, which leads to some pieces getting overcooked and crispy while others stay undercooked and mushy – take an extra minute to distribute them in a single, even layer.
Another common error is pouring the sauce over the potatoes without blending it completely smooth first, as any lumps of cornstarch will create an unpleasant, gummy texture instead of a creamy coating.
Make sure to stir the potatoes halfway through baking to redistribute the sauce and ensure everything cooks evenly, and if the top starts browning too quickly, cover the dish loosely with foil for the remaining baking time.
Finally, resist the urge to dig in right away – letting the casserole rest for 5-10 minutes after baking allows the sauce to thicken up properly and makes serving much cleaner.
What to Serve With Scalloped Hashbrown Potatoes?
These creamy scalloped hashbrown potatoes make a great side dish for just about any main course you’re serving. They pair really well with roasted vegetables like Brussels sprouts or green beans, which add a nice fresh contrast to the rich, cheesy sauce. If you’re looking for protein options, try serving them alongside baked tofu, tempeh steaks, or even a simple lentil loaf for a complete meal. You could also keep things simple with a crisp side salad dressed with a light vinaigrette to balance out the creaminess of the potatoes.
Storage Instructions
Store: Leftover scalloped hashbrown potatoes keep really well in the fridge. Just cover the dish tightly with foil or transfer to an airtight container, and they’ll stay good for up to 4 days. The sauce might thicken up a bit as it sits, but that’s totally normal.
Freeze: You can freeze these for up to 2 months if you want to prep ahead. Let them cool completely first, then wrap the dish tightly in plastic wrap and foil, or portion them out into freezer-safe containers. Thaw overnight in the fridge before reheating.
Reheat: Cover the dish with foil and warm it in a 350°F oven for about 20-25 minutes until heated through. You can also microwave individual portions for 2-3 minutes, stirring halfway. If the sauce seems too thick, just splash in a little soymilk or water to loosen it up.

Ingredients
For the base:
- 2.25 lb hash brown potatoes (I use Ore-Ida frozen cubed potatoes for a firmer texture)
For the sauce:
- 1 1/4 cups water
- 1.25 cups soymilk (I use Silk Unsweetened for a neutral flavor profile)
- 3/4 cup nutritional yeast (gives the sauce its signature cheesy color and flavor)
- 4 tbsp cornstarch
- 1 tbsp lemon juice (freshly squeezed for brighter acidity)
- 2 tbsp tahini (I use Joyva for a smooth, creamy consistency)
- 1.25 tsp salt
- 1.25 tsp onion powder
- 1 tsp miso
- 3/4 tsp garlic powder
- 1/2 tsp smoked paprika
- 1/8 tsp turmeric
- 1/8 tsp black pepper
- 1/4 tsp cayenne pepper
For the topping:
- 1.5 tsp paprika
Step 1: Prepare the Cheese Sauce Base
- 1 1/4 cups water
- 1.25 cups soymilk
- 3/4 cup nutritional yeast
- 4 tbsp cornstarch
- 1 tbsp lemon juice
- 2 tbsp tahini
- 1.25 tsp salt
- 1.25 tsp onion powder
- 1 tsp miso
- 3/4 tsp garlic powder
- 1/2 tsp smoked paprika
- 1/8 tsp turmeric
- 1/8 tsp black pepper
- 1/4 tsp cayenne pepper
In a blender, combine the water, soymilk, nutritional yeast, cornstarch, lemon juice, tahini, salt, onion powder, miso, garlic powder, smoked paprika, turmeric, black pepper, and cayenne pepper.
Blend on high speed for 60-90 seconds until completely smooth and creamy with no lumps.
I like to let the blender run a full minute to ensure the cornstarch is fully incorporated—this prevents any grainy texture in the final sauce.
Set the blended sauce aside.
Step 2: Preheat Oven and Assemble Dish
- 2.25 lb hash brown potatoes
Preheat your oven to 400°F.
While the oven heats, spread the frozen hash brown potatoes evenly in a 9×13 inch baking dish (or similar size), breaking up any large clumps with your hands or a fork so they distribute evenly for uniform cooking.
Step 3: Pour Sauce and Season
- cheese sauce from Step 1
- 1.5 tsp paprika
Pour the cheese sauce from Step 1 evenly over the hash browns, using a spatula or spoon to distribute it throughout the dish and ensure all potatoes are coated.
Sprinkle the 1.5 tsp paprika over the top as a finishing garnish—I find the combination of the smoked paprika already in the sauce with this brighter paprika on top adds nice depth and visual appeal.
Step 4: Bake Until Golden and Set
Place the baking dish in the preheated 400°F oven and bake for 35-45 minutes, until the top is golden brown and the sauce has thickened and set (the potatoes should be tender when pierced with a fork).
The cornstarch in the sauce will firm up as it bakes, creating that classic scalloped texture.
The exact timing depends on your oven and how thawed your frozen potatoes are, so start checking at 35 minutes.
Step 5: Rest and Serve
Remove the dish from the oven and let it rest for 5 minutes before serving—this allows the sauce to set further and makes portioning cleaner.
Serve hot directly from the baking dish or transfer portions to individual plates.
