OMG! SO good!! It is very similar to a sweet potato casserole, but with butternut squash. We loved it! I especially loved the crunchy topping. I want to coat everything in the crunchy topping – cornflakes, brown sugar, pecans, and butter. WOW! This casserole will make the perfect addition to your holiday table.
How to Make Mashed Butternut Squash Casserole
This casserole is very easy to make with only a few simple ingredients. Spray a 9-inch square casserole dish with cooking spray. Set aside. In a large bowl, mix together mashed butternut squash, eggs, sugar, butter, milk, ginger, and coconut extract. Pour the squash mixture into the prepared casserole dish. Bake in a preheated oven. In a small bowl, combine crushed cornflakes, brown sugar, chopped pecans, and melted butter. Remove the casserole dish from the oven. Sprinkle cornflake mixture on top of the casserole and bake for an additional 10 minutes.

That sounds so good! When I was little, my mom baked some butternut squash in the oven, but forgot to poke holes in it! Oh my goodness what a mess!! My brothers & I had to go to the neighbors house while she cleaned it up. Do we need to poke holes in the squash if it is cooked in a slow cooker? Just curious …
Thank you!!
