No-Sugar-Added Sweet Potato Casserole, Diabetic-Friendly

This no-sugar-added sweet potato casserole delivers the comforting flavors of the holiday classic without refined sugars or marshmallows. Roasted sweet potatoes provide natural sweetness, blended with warm spices and a touch of milk for creaminess, then topped with a crunchy pecan-oat streusel. It’s a healthier alternative perfect for Thanksgiving, Christmas, or any fall meal, suitable for diabetics, low-sugar diets, and those seeking nutrient-dense sides.

Sweet potatoes are nutrient powerhouses, rich in vitamin A, fiber, and antioxidants, supporting eye health, digestion, and immune function. By roasting instead of boiling, you concentrate their natural sugars, eliminating the need for added sweeteners. The pecan topping adds healthy fats and texture without overpowering the dish.

Why Choose No-Sugar-Added?

Traditional sweet potato casseroles rely on brown sugar, corn syrup, and marshmallows, spiking blood sugar and adding empty calories. This version uses the inherent sweetness of sweet potatoes, enhanced by spices like cinnamon and nutmeg. It’s lower in carbs, gluten-free adaptable, and vegan-friendly with simple swaps.

• Health benefits: High in beta-carotene, potassium, and vitamin C for better immunity and heart health.
• Diet-friendly: Keto options with cauliflower blends, Whole30-compliant without maple, or plant-based.
• Versatile: Serve as a side, breakfast bake, or meal prep for the week.

Ingredients

Gather simple, wholesome ingredients for the filling and topping. This recipe serves 8-10 as a side dish.

Sweet Potato Filling

• 3-4 pounds sweet potatoes (about 5 medium), scrubbed
• 1/4 cup unsweetened almond milk (or oat milk for creaminess)
• 2 tablespoons pure maple syrup or mashed dates (optional for subtle sweetness)
• 1-2 large eggs (or flax eggs for vegan)
• 1 teaspoon ground cinnamon
• 1/2 teaspoon ground nutmeg
• 1/4 teaspoon ground ginger or allspice
• 1 teaspoon vanilla extract
• 1/4 teaspoon salt
• 2 tablespoons melted butter or coconut oil (dairy-free option)

Pecan Streusel Topping

• 1/2 cup chopped pecans
• 1/3 cup rolled oats (gluten-free if needed)
• 1/4 cup almond flour or whole wheat pastry flour
• 2-3 tablespoons melted butter or coconut oil
• 1-2 tablespoons coconut sugar or monk fruit sweetener (minimal or omit)
• 1/2 teaspoon cinnamon
• Pinch of salt

Pro tip: For a keto twist, blend in steamed cauliflower florets to stretch the sweet potatoes while keeping net carbs low at 6g per serving.

Step-by-Step Instructions

Prep time: 20 minutes | Cook time: 1 hour 15 minutes | Total: 1 hour 45 minutes

1. Roast the sweet potatoes: Preheat oven to 400°F (200°C). Poke holes in sweet potatoes with a fork. Place on a foil-lined baking sheet and roast for 45-60 minutes until fork-tender. Cool slightly, then scoop out flesh (discard skins). This step maximizes natural sweetness.
2. Prepare the filling: Reduce oven to 350°F (175°C). In a large bowl, mash sweet potatoes with an electric mixer or potato masher. Add milk, maple syrup (if using), eggs, spices, vanilla, salt, and butter. Beat until smooth and creamy. Adjust with more milk for desired consistency. Spread into a greased 9×13-inch baking dish.
3. Make the topping: In a medium bowl, combine oats, flour, pecans, cinnamon, salt, and sweetener. Stir in melted butter until crumbly. Sprinkle evenly over the filling.
4. Bake: Bake for 25-35 minutes until topping is golden and casserole is bubbly. For extra crunch, broil 1-2 minutes. Let rest 10 minutes before serving.

Serve warm with roasted turkey, green beans, or as a standalone dish. Leftovers store in the fridge for 4 days or freeze for 2 months.
