As we near closer to the holidays, I am having fun writing my menu!

I want easy, quick recipes that are very delicious and perfect to serve for Thanksgiving Dinner.

This is a no wait sourdough recipe, as it uses sourdough starter/discard straight from the jar. No bulk fermentation or waiting!

I love these quick sourdough recipes especially during the busy holiday season. This is a unique way to use sourdough starter but is absolutely delicious!

Serve along side your favorite dishes. The perfect Thanksgiving table in my opinion has Turkey, sourdough dinner rolls, cranberry sauce, and sweet potato casserole!

My goal every year is to set a table with as few dishes from the grocery store as possible and dishes like this are super easy to make ahead and be prepared for the busy day!

Why I love this sourdough sweet potato casserole

This recipe uses simple ingredients and leans on the natural sweetness of the sweet potatoes.

The perfect side dish that can be made ahead of time and warmed on the day of Thanksgiving or your dinner party.

Using only maple syrup or honey for added sweetener, it is a healthier version of the traditional recipe.

This is a great way to get your kids to eat healthy sweet potatoes.

Step by Step Instructions for making Sourdough Sweet Potato Casserole

Bake the potatoes

Preheat the oven to 350 degrees F.

Wash the sweet potatoes and prick potato skins.

Bake in preheated oven for 45 minutes to an hour or until they can be easily pierced with a fork.

Leave oven on for baking the casserole.

You can also boil the potatoes in a small saucepan after cubing them until fork tender and mash them after they are cooked.

Make Sweet Potato Mixture

Slice baked potatoes in half and scoop out the sweet potato puree.

Add to a large bowl.

*Alternatively, you can cube the sweet potatoes and cook the sweet potato cubes in boiling water until fork tender*

You can then put them through a potato ricer, use an immersion blender, or put them in the bowl of a Stand Mixer with a paddle attachment and mix at low speed.

Add the egg, salt, cinnamon, honey or maple syrup, and vanilla.

Mix well and transfer potato mixture to a Cast Iron Skillet or 9 inch baking dish that has been greased with a little bit of olive oil.

Make Sourdough Topping

In a small bowl add the sourdough starter, cinnamon, honey or maple syrup, salt, and baking powder.

Mix well.

Note: Sourdough starter does not have to come to room temperature if it was taken from the fridge.

Assemble Casserole

Pour the sourdough mixture over the sweet potato mixture.

Spread evenly over the sweet potato mixture or swirl it in with a butter knife.

Try sprinkling with brown sugar if you prefer for an even sweeter casserole.

Bake the Casserole

Bake the assembled casserole in preheated 350 degree F oven for 20-25 minutes or until the topping is lightly golden brown and set.

Variations

This casserole could also be made by topping the sweet potato mixture with my sourdough biscuits and bake for the same amount of time.

Instead of mashing the sweet potatoes, roast potatoes and add the other ingredients before topping. Roasting the potatoes brings out even more sweet flavor.

For a savory sweet potato casserole, leave out the honey/maple syrup, cinnamon, and vanilla. Instead add a pinch of cayenne pepper and some sauteed onions and garlic!

Storage

Store in an airtight container in the fridge for 3-4 days.
