Creamy sauce, chewy kale, sweet potatoes and beans and crunchy breadcrumb topping create a perfect balance of textures as well.

How to Make a Vegan Casserole
In my free e-book “How to Cook without a Recipe,” you learn the fundamental principles of creating a meal from scratch. I also share some examples. This delicious vegan casserole recipe is a great example of how to put those principles to work in your own kitchen.
The foundation of the casserole is a grain (in this case it’s quinoa, but you could substitute others such as buckwheat, rice, barley, or millet). Then you’ll add any other kind of beans you enjoy, root vegetables or pumpkin, chewy greens, and creamy sauces.
As you can see, there’s plenty of room to improvise, which makes it a great recipe for using up what’s in the fridge, being able to shop the sales, and eat seasonally.
To make a perfect flavor profile, you’ll want to be sure to include a variety of taste profiles (sweet, salty, bitter, sour, umami, pungent, astringent) and textures (crispy, chewy, creamy).
The same food can have multiple tastes, so there is no need to use a lot of ingredients. You can always balance the missing tastes by adding spices.
I provide examples for each type of taste in my free e-book book, so be sure to get a copy for your reference (you can download it right away!).
How to Make Sweet Potato Casserole with Black Beans, Kale and Quinoa
This is one of those classic recipes you’ll come back to over and over again because this vegan sweet potato casserole is both delicious and simple.
To make it, start by roasting your sweet potatoes (you can use leftovers for this vegan sweet potato lentil soup) or other veggies. Then boil your beans and quinoa (or any other grains you might opt to use).
Next, make a roasted garlic dressing or vegan buddha bowl dressing for it.
Pro tip: make a large batch of your dressing and use it throughout your week. You could make the Ultimate Vegan Buddha Bowl or dip some fritters in your sauce.
How To Prep And Store Your Vegan Sweet Potato Casserole
If you want to get a head start on your meals at the beginning of the week, you can easily roast your veggies and cook your grain ahead of time, simply combining them and baking them to serve.
You could also make the casserole up ahead of time and freeze it, uncooked. Simply move it to the oven and bake it to serve. If you do this, however, you will notice that it’s a much creamier texture as freezing will change the consistency of your grains and vegetables.
If you have leftovers, simply store them in the fridge in an airtight container for up to a week. To reheat this casserole, microwave or (if you have time!) bake it.

Question - so, dont cook the kale other than in that last 10 minutes? Also, if make ingredients ahead, how long should this cook after assembling, and being at room temp? Still just 10 min?

@Kiki, If you like crunchy kale, then cook it or only 10 min. If you prefer it more soft and cooked through, you can pre-boil it for around 10 minutes. If you pre-cooked the ingredients, I would say increase the cooking time to 15-20 minutes to heat them through. Hope that helps!
