Step-by-Step Instructions
Step 1: Prep the Oven and Dish
Preheat your oven to 375°F (190°C). Grease a 2-quart baking dish lightly with a bit of coconut oil or a spritz of cooking spray.
Step 2: Cook the Sweet Potatoes
Place the cubed sweet potatoes in a large pot and cover with water. Bring to a boil and cook for 15-20 minutes, or until they are very tender when pierced with a fork.
Step 3: Drain the Potatoes
Drain the sweet potatoes thoroughly and return them to the warm pot. Let them sit for a minute to allow any excess steam to evaporate.
Step 4: Create the Creamy Base
Mash the sweet potatoes until smooth. Then, stir in the applesauce, maple syrup, vanilla extract, almond milk, cinnamon, nutmeg, and salt. This creates the luscious, dairy free casserole filling.

Step 5: Transfer to Baking Dish
Spread the sweet potato mixture evenly into the prepared baking dish, smoothing the top with a spatula.
Step 6: Make the Topping
In a small bowl, mix the chopped pecans, melted coconut oil, and oat flour until the pecans are nicely coated. This simple topping adds a delightful crunch.
Step 7: Add the Topping
Sprinkle the pecan topping evenly over the sweet potato mixture.
Step 8: Bake to Perfection
Bake for 25-30 minutes, or until the topping is golden brown and the casserole is heated through and bubbling slightly at the edges.
Pro Tips & Tasty Tweaks

- Storage Tip: Leftovers keep beautifully in the fridge for up to 4 days. Reheat gently in the oven for the best texture.
