Ah, sweet potatoes—nature’s candy! This pecan roasted sweet potato casserole is like a cozy blanket on a chilly evening, wrapping you in warm, nutty goodness. It’s a dish that somehow makes you feel like you’re back at Grandma’s, even if she never quite nailed this particular recipe.
Steps
- Preheat your oven and prepare the butternut squash by placing it in an Instant Pot for a few minutes. This softens the squash and makes the skin easy to remove, allowing you to cube it without it becoming mushy.
- Roast the butternut squash and cauliflower in the oven until tender. This step enhances the flavors and makes the vegetables easier to puree.
- Once roasted, blend the butternut squash and cauliflower until smooth. Adjust the proportions according to taste, using more squash if you prefer a sweeter flavor.
- Prepare the topping by pulsing pecans in a food processor until they form a powder, ensuring you don’t overmix to avoid creating nut butter. Keep some pecans in larger pieces for added texture.
- Assemble the casserole by spreading the pureed mixture into a baking dish. Top it with the prepared pecan mixture, ensuring an even distribution for a crunchy topping.
- Bake the assembled casserole in the oven until the topping is golden and crisp. Allow it to cool slightly before serving to enhance the flavors and improve the texture.
