Dietary Information

This casserole is naturally gluten free and refined sugar free. It can be made fully dairy free by swapping the butter for coconut oil and using a non dairy milk. The texture stays wonderfully silky either way. It’s a great choice to include on a holiday table where guests may have different dietary needs.

Tips or Variations

  • Use maple syrup instead of coconut sugar for deeper autumn flavor.
  • Add orange zest for a brighter, citrusy twist.
  • If you prefer a smoother topping, skip the pecans and use only oat crumble.
  • Leftovers store well in the fridge for up to four days. Reheat gently in the oven to keep the topping crisp.

Serving Suggestions

This casserole pairs beautifully with roasted turkey, green beans, stuffing, or a fresh fall salad. It also makes a lovely addition to a Friendsgiving potluck because it travels well and reheats easily.

Fun Facts

Sweet potatoes became a holiday staple in the United States in the early 1900s when cooks began pairing them with warm spices like cinnamon and nutmeg. Their natural sweetness makes them perfect for lightened up desserts and sides.

FAQ

Can I prepare it ahead of time?
Yes. Assemble the casserole up to the point of baking, cover, and refrigerate for up to 24 hours. Add 5 to 10 extra minutes of bake time.

Can I freeze this recipe?
Yes. Freeze after baking. Reheat in the oven until warmed through.

Can I leave out the eggs?
