What Ingredients You Will Need

This recipe uses simple, wholesome ingredients, and you likely have most of them in your kitchen. Let’s break it down:

• Sweet Potatoes: About 4 large sweet potatoes or 5 medium ones, peeled and cut into chunks.
• Butter: 1/2 cup unsalted butter for browning (or use vegan butter if preferred).
• Fresh Sage: A handful of fresh sage leaves for that earthy, aromatic flavor.
• Milk: 1/3 cup whole milk or your favorite plant-based milk.
• Brown Sugar: 1/4 cup, for a hint of sweetness.
• Salt: 1 teaspoon, to balance the flavors.
• Ground Cinnamon: 1/2 teaspoon, for a warm, spicy note.
• Nutmeg: A pinch, optional but recommended for added depth.
• Pecans: 1/2 cup, chopped (or use walnuts for a twist).
• Breadcrumbs: 1/2 cup, for a crunchy topping.
• Olive Oil: A drizzle for toasting the breadcrumbs and pecans.

This ingredient list is customizable—swap out pecans for almonds or use maple syrup instead of brown sugar. The possibilities are endless!

Equipment Needed

• Large Pot: For boiling the sweet potatoes.
• Skillet: To brown the butter and toast the sage leaves.
• Mixing Bowls: To mash the sweet potatoes and prepare the topping.
• Potato Masher or Fork: For mashing the sweet potatoes.
• Baking Dish: A 9×13-inch dish works perfectly.
• Whisk: To mix the brown butter and milk evenly.

If you don’t have a potato masher, a sturdy fork works just as well. Also, a non-stick skillet is ideal for browning butter and toasting toppings without sticking.

Preparation Method

1. Boil the Sweet Potatoes: Peel and chop the sweet potatoes into equally sized chunks (about 1-inch). Place them in a large pot, cover with water, and add a pinch of salt. Bring to a boil and cook for about 15-20 minutes, or until fork-tender.
2. Make the Brown Butter: In a skillet, melt the butter over medium heat. Keep stirring until the butter turns golden brown and emits a nutty aroma. This should take about 5-6 minutes. Add the fresh sage leaves and let them sizzle until crispy, about 1 minute. Remove from heat and set aside.
3. Mash the Sweet Potatoes: Drain the cooked sweet potatoes and transfer them to a large bowl. Mash thoroughly using a potato masher or fork until smooth. You can leave a few chunks for texture if preferred.
4. Mix the Filling: Add brown sugar, salt, cinnamon, nutmeg, and the browned butter (reserve the sage leaves for topping). Slowly whisk in the milk until the mixture is creamy and well combined.
5. Prepare the Topping: In a small bowl, mix the chopped pecans, breadcrumbs, and a drizzle of olive oil. Toss to coat evenly.
6. Assemble the Casserole: Spread the sweet potato mixture evenly in your baking dish. Sprinkle the pecan and breadcrumb topping over the surface. Arrange the crispy sage leaves on top for a beautiful finish.
7. Bake: Preheat your oven to 375°F (190°C). Bake uncovered for 25-30 minutes, or until the topping is golden and crispy.
8. Serve: Let the casserole cool for 5 minutes before serving. Enjoy the warm, comforting flavors!

Cooking Tips & Techniques

• Don’t Rush the Brown Butter: The key to getting that nutty, caramelized flavor is patience. Keep stirring and watch closely to avoid burning.
• Choose the Right Potatoes: Go for orange-fleshed sweet potatoes for the best flavor and texture. They’re naturally sweeter and creamier.
• Keep It Creamy: Don’t skip the milk—it helps achieve that silky texture. If you’re dairy-free, almond or oat milk works well.
• Crunchy Topping Tips: Toast the pecans and breadcrumbs lightly in a dry pan before adding them to the casserole. This boosts flavor and ensures crunch.
• Make It Ahead: Prep the filling and topping separately, then assemble and bake right before serving. Perfect for holiday planning!

Variations & Adaptations

• Vegan Version: Replace butter with vegan butter and use almond or coconut milk instead of dairy milk.
• Nut-Free Option: Skip the pecans and use sunflower seeds or toasted pumpkin seeds for the topping.
• Seasonal Swap: Add a hint of orange zest for a citrusy twist or sprinkle dried cranberries for a festive touch.
• Spice It Up: Add a pinch of cayenne pepper or smoked paprika for a savory kick.
• Low-Carb Alternative: Swap sweet potatoes with mashed cauliflower for a lighter version.
