Au gratin vegetables pack in serious flavor with this hearty dish! Transforming this recipe into a dairy-free Paleo dish is easy with ingredients like almond milk, ghee, and cassava flour. The result is a smooth and creamy sauce that turns roasted cauliflower into au gratin perfection.
Traditional recipes typically incorporate carb-heavy potatoes, but this version swaps in roasted cauliflower to add more dimension and nutrition. The béchemal sauce is the standout of the recipe and consists of a creamy roux made with ghee and cassava flour. Ghee is used for its “buttery” taste and healthy fats, while also boasting a higher smoke point than traditional butter.

Wheat-free cassava flour is used to thicken the béchemal sauce, without adding any grittiness or deviation from traditional flavor. As an bonus, this recipe uses a “breadcrumb” topping made with almond meal, nutritional yeast, and oregano for extra crunch. Tip: You can also use this “breadcrumb” combo for other recipes like chicken fingers or veggie fries.
Get started by roasting the cauliflower in the oven for 25 minutes. While the cauliflower roasts, stir together the “breadcrumb” ingredients in a mixing bowl and set aside. Next, whip up the sauce by melting ghee in a saucepan and whisking in cassava flour, followed by the almond milk. Add in the remaining seasonings and let the sauce come to a low boil, whisking occasionally. After 3-5 minutes, the sauce will begin to thicken. Switch the oven to broil and remove the cauliflower from the oven.
Pour the sauce on top of the cauliflower and generously sprinkle the “breadcrumbs” on top. Return to the oven and broil for five minutes, or until the top is lightly browned. Serve hot alongside your favorite Paleo entrée and enjoy!
