Step‑by‑Step Instructions for Gluten Free Sweet Potato Casserole
Step 1: Preheat the Oven and Bake Sweet Potatoes
Begin by preheating your oven to 450°F (232°C). Wash and dry the sweet potatoes, then place them on a lined baking sheet. Bake for about 30 minutes or until they are fork-tender, giving off a sweet aroma. The skins should be slightly crisp while the insides become soft and creamy, perfect for your Gluten Free Sweet Potato Casserole.
Step 2: Cool, Peel, and Slice Sweet Potatoes
Once baked, remove the sweet potatoes from the oven and allow them to cool for approximately 10 minutes. Carefully peel the skins off; they should slide off easily. Slice the sweet potatoes into chunks and transfer them to a large mixing bowl, ready to be mashed into a smooth filling for your casserole.
Step 3: Lower Oven Temperature and Mix Ingredients
Reduce the oven temperature to 350°F (175°C). In the bowl with the sweet potatoes, add melted dairy-free butter, almond milk, sugar, salt, nutmeg, and cinnamon. Using a hand mixer, combine the ingredients on low speed for about 2 minutes until well blended, ensuring a creamy texture that lays the foundation for your delicious Gluten Free Sweet Potato Casserole.
Step 4: Incorporate Eggs for Fluffiness
Next, crack in the eggs and continue to mix at medium speed for about 5 minutes. You’re aiming for a light and fluffy filling; it should be well-combined and airy at this stage. This step is crucial for achieving the perfect texture in your casserole, enhancing both taste and presentation.
Step 5: Transfer to Casserole Dish
Carefully pour the sweet potato mixture into a greased 1.5-quart casserole dish, spreading it evenly with a spatula. This will be the base for your Gluten Free Sweet Potato Casserole. Bake uncovered in the preheated oven for about 15 minutes, allowing it to set before adding the topping.
Step 6: Prepare the Pecan Topping
While the casserole base is baking, combine the chopped pecans, gluten-free flour, and brown sugar in a mixing bowl. Stir these ingredients together until evenly blended. This crunchy topping will provide a delightful contrast to the smooth filling, enhancing the overall experience of your holiday dish.
Step 7: Add Topping and Marshmallows
After the initial baking, remove the casserole and sprinkle the pecan topping evenly across the surface. For an extra sweet touch, add gluten-free marshmallows in a decorative diagonal pattern. Return the casserole to the oven and bake for an additional 20 minutes, until the topping is golden brown and the marshmallows are lightly toasted.
Step 8: Cool Before Serving
Once baked, take the casserole out and let it cool for 10-15 minutes before serving. This resting period allows the flavors to settle and makes it easier to slice into portions. Your tempting Gluten Free Sweet Potato Casserole is now ready to grace your holiday table, offering warmth and comfort in every bite.
