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.

Notes

This spice rub is delicious, great for roasting veggies, tofu, beans and more! If you’re not vegan you can also try this spice blend on your choice of protein but I highly suggest trying with veggies for that added flavour and caramelization.
