1-Step One: Prepare the Sweet Potatoes

You have three cooking options for your sweet potatoes, each producing slightly different results:

Microwave Method (Fastest): Wash your sweet potatoes and wrap each one in a wet paper towel. Microwave for 5 minutes per side, checking for tenderness by inserting a fork. Total cooking time runs about 10 minutes for two large potatoes. Let them cool to room temperature before peeling off the skins and mashing the flesh.

Roasting Method (Most Flavorful): For deeper, caramelized sweetness, roast whole sweet potatoes at 400°F for over an hour until completely soft. This method concentrates flavors but requires more time.

Boiling Method (Classic): Peel and slice sweet potatoes into rounds, then boil in water for 20-25 minutes until fork-tender. Drain well before mashing to avoid watery filling.

Whichever method you choose, you need exactly 2 cups of mashed sweet potatoes for this recipe. Allow the mash to cool completely before proceeding with the filling.

2-Step Two: Preheat and Prepare Your Pan

Preheat your oven to 350°F while you prepare the filling. Choose your pan wisely for best results:

* 10- or 12-inch cast iron skillet: My top choice for even heat distribution and beautiful presentation right from oven to table
* 9-inch cake pan: Works perfectly if you prefer a deeper dish with more defined layers

Grease your chosen pan generously with cooking spray, olive oil, avocado oil, or butter. This prevents sticking and makes serving much easier.

3-Step Three: Mix the Sweet Potato Filling

In a large mixing bowl, combine your cooled mashed sweet potatoes with the eggs, heavy cream (or coconut milk for dairy-free), and vanilla extract. Beat everything together until well combined. A hand mixer works great here, but a sturdy whisk and some elbow grease do the job too.

Add the brown sugar (or coconut sugar), ground cinnamon (or pumpkin pie spice), and sea salt to the mixture. Mix thoroughly until no streaks of spice remain. The filling should look smooth and evenly colored throughout.

4-Step Four: Spread the Filling

Pour the sweet potato mixture into your prepared pan, using a spatula to spread it evenly across the surface. The filling layer should be uniform in thickness for consistent baking.

5-Step Five: Create the Streusel Topping

In a separate bowl, combine the flour (or gluten-free flour), quick oats, brown sugar, and ground cinnamon. Pour in the melted butter (or coconut oil) and stir everything together until the mixture becomes crumbly and no dry flour remains.

The topping should clump together when squeezed but break apart easily when crumbled. Sprinkle this mixture evenly over the sweet potato filling, covering the entire surface with buttery, cinnamon-scented crumbs.

6-Step Six: Bake to Golden Perfection

Cover the pan with aluminum foil and bake at 350°F for 15 minutes. This initial covered baking time allows the filling to set without drying out.

Remove the foil and continue baking for 30-40 additional minutes until the topping turns golden brown and crispy, and the filling is set. You’ll know it’s done when the edges bubble slightly and a knife inserted in the center comes out clean.

7-Step Seven: Serve and Enjoy

Let your sweet potato crumble rest for about 10 minutes before serving. This resting period allows the filling to firm up slightly for cleaner slices. Serve warm, optionally topped with vanilla ice cream or a dollop of fresh whipped cream.
