Ingredients
  

For the Gratin
  • 1 large butternut squash peeled and sliced thinly
  • 2 medium shallots or use yellow onion
  • 2 cloves garlic minced
  • 1 tbsp butter or olive oil for dairy-free
  • 2 tbsp gluten-free flour certified gluten-free if needed
  • 2 cups vegetable stock or chicken stock for non-vegetarians
  • 1 cup heavy cream or coconut cream for dairy-free
  • 1 cup Parmesan cheese grated, or nutritional yeast for vegan
  • 5 leaves sage fresh, can substitute with thyme
  • 1 tsp onion powder optional
For the Topping
  • 2 tbsp chives freshly chopped for garnish

Equipment

  • 9x13-inch baking dish
  • medium saucepan
  • Mandoline Slicer

Method
 

Step-by-Step Instructions
  1. Preheat your oven to 400°F (200°C).
  2. Peel and thinly slice the butternut squash into half rounds, about 1/4 inch thick.
  3. Melt a tablespoon of butter in a medium saucepan over medium heat. Add shallots and garlic, sauté for 1-2 minutes.
  4. Stir in gluten-free flour to the shallots and garlic, forming a roux. Cook for 1-2 minutes until golden.
  5. Gradually whisk in vegetable stock, making sure there are no clumps. This forms the base for your creamy sauce.
  6. Slowly pour in heavy cream and stir. Add sage leaves, onion powder, and pepper, stirring until smooth.
  7. Grease a 9x13 inch baking dish with butter. Pour a third of the creamy sauce into the dish, then layer half of the squash slices.
  8. Repeat layering with the remaining squash and sauce, finishing with the last third of creamy sauce on top.
  9. Cover with parchment paper and aluminum foil, bake for 20 minutes. Remove the cover to sprinkle on Parmesan cheese.
  10. Return to the oven uncovered and bake for an additional 10 minutes until cheese is golden brown.
  11. Garnish with freshly chopped chives and serve warm.
