Vegan Potato Bake / Casserole
When making a vegan casserole with potatoes you need to think about two things: what vegetables go well with potatoes (if you choose to have any) and how to make a vegan creamy sauce.
Unlike any other vegan potato recipes, this vegan potato casserole is pretty easy to make and fuss free. You just quickly dice all potatoes without the need of a mandoline at all. Much easier and quicker than an au-gratin or scalloped potatoes.
Ingredients For This Vegan Potato Bake Dish
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; Portobello or champignon mushrooms are perfect too.
- Cooked chickpeas – about half of a can, for thickening the sauce. Whole food thickeners are better than processed powders.
- Leeks, or white onions for flavor.
- Garlic cloves – for flavor.
- 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;

How To Make The Vegan Potato Bake / Casserole
Step 1. Prepare the vegetables:
- Peel and cut the potatoes into cubes. Place in water to prevent browning.
- In a large pan, melt the vegan 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.
Step 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.
- Add it in the pot and mix. Let it simmer for a couple of minutes.
Step 3. Combine and cook the potatoes:
- Mix in the diced potatoes and cook covered with a lid for 25-30 minutes (medium-low heat).
Step 4. Assemble the vegan potato casserole:
- Preheat oven to 430F (220C) and prepare a casserole dish.
- Spoon half the potato mixture;
- Sprinkle on top with half of the leek and mushroom mixture and 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!
Prepping Tip
To cook the potatoes faster, cut them in even, small squares about 1/3″ in diameter.
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.
Best Vegan Baked Potato Toppings
- Salsa
- Pesto
- Chives or other herbs
- Vegan cheese

Tips For A Perfect Vegan Potato Bake Casserole
- 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.
- 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.
- 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 bake into a more substantial dish by adding other vegetables like brussels sprouts, zucchini, broccoli rabe or even other root veggies.
- Bacon is out of option, but you want that smoky flavor? then use some smoked paprika in the sauce.
Potato Casserole Storing
- 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.
What Goes Well With This Vegan Potato Bake
- A vegan coleslaw made with a creamy avocado dressing, crunchy and full of fiber.
