Ingredients
For this scrumptious sweet potato casserole, you’ll need:
- 5 large sweet potatoes (about 3 pounds): Look for smooth skins and firm flesh; organic is an excellent option if available.
- 1 tablespoon extra-virgin olive oil or melted butter (plus more for drizzling): I recommend using high-quality olive oil for the best flavour.
- 1¼ cups milk (plus more if necessary): Use your preferred milk; for a richer taste, whole milk or plant-based alternatives work wonderfully.
- 1 teaspoon ground ginger: Fresh grated ginger can also be used for an added kick!
- ¾ teaspoon sea salt
- ¼ teaspoon freshly ground black pepper
- ¼ cup fresh sage leaves (for garnish)
- ⅔ cup whole rolled oats: A sturdy rolled oat brand, such as Bob’s Red Mill, will work well.
- ½ cup pecans (plus more for garnish): Chopped or whole, depending on your preference.
- ½ cup walnuts (plus more for garnish)
- 1 garlic clove: Fresh garlic makes a noticeable difference; feel free to mince it for added pungency.
- 1 tablespoon plus 1 teaspoon maple syrup: Using pure maple syrup adds an incredible depth of flavour.
- 2 tablespoons extra-virgin olive oil or melted butter
- ½ teaspoon dried thyme leaves
- ½ teaspoon minced fresh rosemary
- 1½ teaspoons sea salt
- ¼ teaspoon freshly ground black pepper
Prep Notes: Ensure your butter is at room temperature for easier mixing. If you wish for a creamier filling, consider adding a few extra tablespoons of milk as you mix.
Step-by-Step Instructions
- Preheat your oven: Set it to 425°F (220°C). Line a baking sheet with foil and brush a 9×13-inch baking dish with olive oil to prevent sticking.
- Roast the sweet potatoes: Use a fork to poke a few holes into each sweet potato. Place them on the baking sheet and roast for about 60 minutes, or until very tender. They should feel soft when gently squeezed with an oven mitt.
- Make the crumble topping: In a food processor, combine the oats, pecans, walnuts, garlic, maple syrup, olive oil, thyme, rosemary, salt, and pepper. Pulse until just combined; you want it crumbly but not overly processed. Set aside.
- Prepare the sweet potato mixture: Once the sweet potatoes are cool enough to handle, scoop the flesh out of the skins and place it into the food processor. Add the olive oil, milk, ginger, salt, and pepper. Process until smooth and creamy.
- Spread the filling: Transfer the sweet potato mixture into your prepared baking dish, spreading it evenly.
- Add topping and bake: Sprinkle the crumble topping over the sweet potato layer. Add any extra nuts and fresh sage leaves for garnish. Drizzle a little olive oil on top. Bake for 20 minutes or until the topping is golden brown and crisp.
Chef’s Tips: When roasting sweet potatoes, make sure they’re evenly sized for uniform cooking. If the sweet potato mixture seems too thick, add a splash more milk until you reach your desired consistency.
Common Mistakes to Avoid: Don’t skip the holes in the sweet potatoes! Otherwise, they might explode in the oven. Ensure the casserole is baked long enough for the topping to crisp up nicely.
