Preheat your oven to 350°F. Take a 2-quart baking dish or a 9-inch baking pan and coat it with non-stick spray to prevent our casserole from sticking.
In a mixing bowl, gather all the ingredients for the sweet potato mixture. Beat them together until the mixture is smooth and creamy. Oh, the sweetness of the potatoes combined with the butter is a joy!
Spread this luscious sweet potato mixture evenly in your prepared baking dish.
Now, let’s move on to the crumb topping! In another bowl, blend all the topping ingredients until well mixed. This rich crumbly topping will give our casserole that irresistible crunch we crave.
Sprinkle the topping generously over the sweet potatoes, allowing every bit to mingle together.
Place the dish in the preheated oven and bake for 35 minutes, or until it’s bubbly and hot. You’ll know it’s ready when your kitchen is filled with the most delightful aroma.
Once baked, remove it from the oven and let it stand for 10 minutes. This resting time will make serving so much easier.
