Hot, savory breakfast casseroles are what I crave as the weather begins to bite, and this savory, delicious Vegan Spinach Potato Casserole is my top favorite right now.
I love how the crunchy breadcrumbs on top complement the creamy, potato-ey spinach and sausage filling. Bonus: it's hearty and filling and utterly good for you.
For those of you cooking for kids, they'll love it too. Bake it up this holiday season for a small or big family--you can easily double or halve the ingredients. And come back and tell me all about it!
Helpful tips
- Slice the potatoes thin, as you would for a gratin, which will help them cook even faster. I like cooking the potatoes separately first if I am layering them on at the top--you don't have to do this. If you want to save yourself the trouble, cube the potatoes in a small dice and mix them into the spinach filling. Add the potatoes right after the onions to the skillet and proceed with the rest of the recipe.
- I added sausage to this casserole, which makes it really kid-friendly (or at least my kid-friendly). But you can leave it out or sub it with seasoned cubes of tofu.
- The cheese is likewise something you could leave out, but it's nice in there. We are layering many strata of deliciousness into this casserole and each one adds even more flavor to your recipe.
- Make sure your breadcrumbs are golden and crunchy when you pull this casserole out of the oven. You can turn on the broiler for a couple of minutes if they aren't.

Servings 6 servings
Calories 421kcal
Ingredients
- 2 medium potatoes (very thinly sliced, as you'd do for a gratin)
- 2 tbsp extra virgin olive oil (divided)
- 1 medium onion (finely chopped)
- 4 cloves garlic (finely minced)
- 14 oz vegan sausage (crumbled. By a gf or soy-free brand based on your diet preference)
- 3 cups baby spinach (roughly chopped)
- 4 crimini mushrooms (or button mushrooms)
- 2 tbsp sage (2 tsp if using dry)
- 2 tbsp parsley (chopped)
- 2 tbsp all purpose flour (use gf all purpose flour if you're glutenfree)
- 2 cups nondairy milk
- ½ tsp garlic powder
- ½ tsp onion powder
- ½ tsp oregano
- 8 oz vegan cheese shreds (optional)
- 1 cup breadcrumbs (use gf breadcrumbs if gluten-free)
- 1 tsp thyme
- Salt and ground black pepper to taste
- 2 tbsp vegan parmesan (optional)
- Scallions or parsley (for garnish, chopped)
Instructions
- Place the potatoes in a microwave-safe dish, add water to cover, and blitz 5-8 minutes on high or until the potato slices are tender but not falling apart.
- Mix or blend the nondairy milk with the garlic and onion powders, oregano and black pepper and salt and set aside.
- Preheat the oven to 425 degrees Fahrenheit
- Heat a 10-inch cast iron skillet or an oven-safe skillet over medium-high heat. Add a tablespoon of the oil. Add the garlic and onions with a dash of salt and pepper and saute until the onions get translucent.
- Add the crumbled sausage to the skillet and saute for a couple of minutes. Add the baby spinach, mushrooms, sage and parsley to the skillet and saute until the spinach has wilted.
- Add the flour to the skillet and stir until the flour disappears into the vegetables. Pour in the nondairy milk mixture and mix well. Add more salt and pepper at this point if needed. The milk should thicken quite a bit.
- Turn off the heat and arrange the potato slices all over the top. Sprinkle the cheese shreds over the top.
- Mix the breadcrumbs with the thyme, vegan parmesan, if using, the remaining oil and salt and ground black pepper to taste. Scatter over the cheese layer.
- Bake for 30 minutes or until the casserole is bubbling and the breadcrumbs are crunchy and golden-brown.

This looks perfect for the Thanksgiving brunch I am planning to take my Dad in assisted living. Can it be put together ahead of time and baked at the last minute?
Hi Lauren, yes, you can put the base together first and freeze. Thaw, top with the breadcrumbs and bake before serving.
i absolutely love your recipes and have cooked one in three of them and they all turn our great but - please - I need to print out all of your recipes so can i ask - selfishly please - try to make them printable on ONE page rather than two - unnecessary pages - I have to keep copying in to WORD to print a one page document! But this recipe I am cooking tonight for my meat-eating husband - who is being moved over to vegetarian sooner than expected - little does he know that he is now almost vegan!!
Hi Catherine, thanks for the kind words and also for letting me know that the recipe card is running into two pages. I am going to try and resolve that. I do hope your husband and you enjoy the casserole— I love sneaky tricks too when it comes to food lol, ❤️❤️
I love your subterfuge, love to see the look on his face when you tell him one day!
