Sweet Potato Casserole Ingredients

For the Base
• Sweet Potatoes – The star of the dish, providing natural sweetness and creaminess; roasting enhances their flavor.
• Eggs – Essential for adding structure and richness to the sweet potato purée.
• Half-and-Half – Contributes creaminess; can be swapped with regular milk or a dairy-free alternative for those with lactose sensitivities.
• Dark Brown Sugar – Deepens the flavor profile; light brown sugar works in a pinch.
• Unsalted Butter – Adds delicious richness; substitute with margarine or vegan butter for a dairy-free version.
• Kosher Salt – Balances the sweetness; regular salt can be used if kosher isn’t on hand.

For the Topping
• Cornflakes – Creates a uniquely crispy topping; choose gluten-free if necessary for a nut-free Sweet Potato Casserole.
• Ground Cinnamon – Adds warmth and complements the sweet potatoes’ natural flavor; nutmeg can be a delightful alternative.
• Marshmallows – Optional for those who love that traditional sweetness; feel free to omit for a lighter dish.

Step‑by‑Step Instructions for Nut-Free Sweet Potato Casserole with Crunchy Cornflake Topping

Step 1: Roast Sweet Potatoes
Preheat your oven to 350°F (175°C). In a 13×9″ baking dish, place the peeled and cubed sweet potatoes, ensuring they are spread out evenly. Cover the dish tightly with foil and bake for 50-60 minutes, or until the sweet potatoes are tender and easily pierced with a fork. Let them cool slightly before handling.

Step 2: Prepare Egg Mixture
In a large mixing bowl, whisk together the eggs, half-and-half, dark brown sugar, melted butter, and kosher salt until well combined. This creamy mixture will enhance the sweet potato casserole’s rich texture. Set it aside while you concentrate on creating the sweet potato purée to blend all the fantastic flavors together.

Step 3: Make Sweet Potato Purée
Using a food processor, blend half of the roasted sweet potatoes with half of the egg mixture until smooth and creamy. Transfer this purée to a large bowl. Repeat this process with the remaining sweet potatoes and egg mixture, ensuring a velvety consistency. Once complete, combine all the purée back into the baking dish for the casserole.

Step 4: Combine Topping
In a resealable plastic bag, combine the cornflakes, ground cinnamon, dark brown sugar, melted butter, and a pinch of salt. Seal the bag and shake vigorously until the cornflakes are evenly coated with the sweet mixture. This crispy topping will provide a delightful crunch to your Nut-Free Sweet Potato Casserole.

Step 5: Assemble & Bake
Carefully layer the cornflake topping diagonally across the sweet potato purée in the baking dish. If you’re using marshmallows, sprinkle them over the top for an extra layer of sweetness. Bake the casserole in the oven for 25-30 minutes, or until the marshmallows are golden brown and the edges are slightly bubbling, creating a delicious contrast with the creamy filling.

Sweet Potato Casserole Recipe FAQs

What type of sweet potatoes should I use for this casserole?
For the best flavor and creaminess, I recommend using orange-fleshed sweet potatoes, like Beauregard or Jewel varieties. They are naturally sweet and will yield a rich and velvety texture in your casserole.

How long can I store leftover sweet potato casserole in the fridge?
Absolutely! Leftovers can be stored in an airtight container in the fridge for up to 3 days. Just make sure to reheat it gently in the oven to maintain its delightful texture.

What if my sweet potato purée is lumpy?
No worries! If your purée ends up a little lumpy, just remix it in the food processor until smooth. Alternatively, you can use a potato masher for a chunkier texture if that’s your preference. The key is to ensure all sweet potatoes are fully cooked for that silky finish.
