Ingredients For This Vegan Potato Casserole
What you need:
- potatoes – I used russet potatoes, but red skinned potatoes are the second best option.
- mushrooms – I used baby shiitake mushrooms, but you can use any you like.
- cooked chickpeas – about half of a can, for thickening the sauce
- leeks, or white onions
- garlic cloves
- vegetable stock – for the sauce, it will enhance the flavor with aromatic vegetables
- non dairy milk – for the sauce
- vegan butter – for sautéing the leeks, it will also provide additional buttery flavor
- Dijon mustard – the tang will temper the richness of the dish
- vegan feta cheese – for extra creaminess, but it’s totally optional
- salt

How To Make The Vegan Potato Bake / Casserole
1. Prepare the vegetables. Peel and cut. In a large pan, melt butter over medium heat. Mix in the chopped leeks and garlic, cook until golden and soft, then add the chopped mushrooms and cook for another 2-3 minutes until tender. Remove everything from the pan in a bowl.
2. Prepare the sauce. In the same pan (still on stove), add the non dairy milk, Dijon mustard and salt. In a blender mix together the vegetable stock with chickpeas until silky smooth. This mixture will serve as a thickener so we won’t need any flour. Then add it in the pot and mix.
3. Combine and cook the potatoes. Mix in the diced potatoes and cook covered with a lid for 25-30 minutes (medium-low heat).
4. Assemble the vegan potato casserole. Preheat oven to 430 F and prepare a casserole dish. Spoon half the potato mixture; sprinkle with half of the leek and mushroom mixture, half of the vegan feta cheese (if using). Then repeat with another layer of potato, mushrooms and cheese. Bake until the potatoes are tender and bubbling, 25 to 30 minutes. Sprinkle with favorite greens and serve!
Easy Vegan Potato Bake
What makes this vegan potato bake extra-easy and quick is that the potatoes are cooked right in the sauce and transferred in the casserole dish when they’re already tender.
Prepping tips: to cook the potatoes faster, cut them in even, small squares about 1/3″ in diameter.
Best Vegan Baked Potato Toppings
- Salsa
- Pesto
- Chives or other herbs
- Vegan cheese

- A vegan sauce (dressing) to drizzle on top, like this ranch or avocado dressing.
Tips For A Perfect Vegan Potato Casserole
1. When you put in the potato casserole, it might look “liquidy”, once baked and cooled a bit (about 15 minutes) it will thicken up perfectly.
2. Short on time? Prepare this vegan potato bake the day before (assemble the casserole), store in the fridge and bake it the next day, you’ll have it ready in just 30 minutes.
3. The best pan: When making casseroles my go to pan is this 3 qt glass 9×13 inch pan: it has a lid and is perfect for storing the leftovers.
Substitutions and Add-ins
- You could even turn this vegan potato casserole into a more substantial dish by adding other vegetables like brussels sprouts, zucchini, broccoli rabe or even other root veggies.
- If you’re not entirely vegan, you can also use some bacon, or some other chopped meat.
- Bacon is out of option, but you want that smoky flavor? then use some smoked paprika in the sauce.
How To Store The Vegan Potato Casserole
Storing leftovers: Cool 1 hour in the dish before refrigerating; cover and chill in the fridge for up to 3 days.
Make ahead: this potato bake can be prepared the day before and refrigerated overnight. Prepare everything and place in the casserole and proceed with the oven step when ready.
Freezing: Freeze it cooked, for up to 3 months. The best way to defrost this potato bake is to let it slowly thaw in your refrigerator overnight. To reheat, cover with foil and rewarm in 350 F oven, 15 to 20 minutes.
