Get Your Oven Ready: Heat your oven to 400°F, line a baking sheet with foil, and grease your 9x13-inch dish with cooking spray for easy cleanup later.
Roast Those Veggies: Toss your sweet potatoes and carrots with olive oil, spread them on the baking sheet, and roast for 30 minutes until they're golden, stirring once or twice.
Make the Topping: Mix your chopped pecans with maple syrup in a small bowl until they're all coated nicely, then set aside for later use on top.
Blend It Up: Put your roasted veggies in the food processor, add ginger, orange zest, orange juice, and coconut milk, then blend until it's smooth and creamy.
Add the Spices: Toss in cinnamon, nutmeg, salt, and pepper into the processor, pulse until mixed well, taste it, and adjust the spices however you like them.
Bake and Serve: Turn your oven down to 350°F, spread the mixture in your prepared dish, top with maple pecans, and bake 40 minutes until hot and lightly brown.
