Nothing beats a yummy, savory sweet potato casserole. It’s a classic dish that seriously never gets old. Most people have a recipe that has been passed on for generations, and with this recipe, I’ve taken a classic dish and just added a kick to it. The best part of this vegan sweet potato casserole recipe is that you can switch up the sweet potatoes and use vegan yams, squash, or a mix of all three. I’ve used a yummy winter-warming spice blend that is the icing on top of the cake with this savory dish – it’s so flavorful and delicious. Imagine something so buttery and sweet, but yet tasty and salty, all coated in this delicious spice blend.

Tips and Tricks
- Slicing: Use a mandoline for even slicing – it makes for uniform cooking and is much quicker, but be careful as they’re very sharp.
- Prep Ahead: Pre-make the spice blend to save time on cooking day and store in an airtight container.
- Skin On: Leave the skin on for added nutrition – just wash and dry the potatoes thoroughly before cutting.
- Fresh Herbs: Top with aromatic herbs like thyme, sage, or rosemary when serving for that perfect green finishing touch.
Variations
- Root Vegetables: Try parsnips, white potatoes, or yams for a unique twist on this classic dish.
- Spice Blend: Customize the winter spices based on your preferences – more cinnamon for sweetness or paprika for smokiness.
- Vegan Butter: Olive oil or coconut oil can substitute for vegan butter if preferred.

How to Store Leftovers
Store leftovers in an airtight container in the refrigerator for up to four days. Reheat in the oven at 350°F to restore the crispy edges and bubbly texture.
Common Questions
Yams have a different texture and flavor, with tough brown skin like tree bark and a more yucca-like consistency compared to the sweeter, softer sweet potatoes.
You can slice and arrange the sweet potatoes a day ahead, but add the spice blend and liquid just before baking for best results.
Look for a beautiful bubbly glaze and tender potatoes that pierce easily with a fork – this usually takes about 1 hour total cooking time.
A sharp knife works fine – just try to keep slices as even as possible, about 1/4 inch thick, for uniform cooking.
This version is savory-focused with natural sweetness from the potatoes, balanced by the spice blend and Dijon mustard for complexity.
Yes! Divide into smaller baking dishes or ramekins and reduce cooking time by 10-15 minutes, watching for doneness.
The foil covering for the first 30 minutes steams the potatoes, then removing it allows for caramelization while the liquid keeps everything moist.

I’m a bit confused does the Winter-Warming Spice blend consist of the spices listed? Or is it a separate mixture of spices for the recipe? And what is Nature’s Way Immune Blend?
Yes, the spice blend is the spices listed. You can omit the Immune blend!
I can’t find the Nature’s way immune blend powder anywhere. Can you provide a link or outline alternatives, as it’s a large piece of the spice blend? Thanks.
Hey Lissy, it’s only 1 tbsp. you can completely omit. It’s not necessary.

Definitely tried this out because of the beautifully taken photo. Roasting recipes are great when I’m too lazy to full on prepare and cook something, and this recipe was so delicious! The crunchy, soft, savory, and sweet all blended together wonderfully. The mandoline slices is really what made the recipe unique. I am definitely trying that with different veggies next time.
This makes me so happy, David! So glad you enjoyed this dish!
