Start by peeling the squash and sweet

potatoes.

Add each one in a separate pot, cover with water, and allow them to cook until they are soft. This should take around 17-20 minutes.

Once they are cooked, drain the squash and sweet potato and add each one to a separate bowl.

Preheat your oven to 350 degrees Fahrenheit.

Spray two medium loaf pans with oil and set them aside.

In the bowl with the cooked squash, add the grated onion, oil, eggs, salt, pepper, and potato starch.

Using an immersion blender, blend the mixture until it is smooth.

Divide the mixture between the two loaf pans. Bake for 30 minutes.

While the first layer is baking, add the rest of the ingredients to the bowl with the sweet potato and blend with an immersion blender until smooth.

Once the squash layer comes out of the oven, layer the sweet potato mixture over it and bake for 50 minutes.
