Ingredients

Scale

Sauce

  • 3 tablespoons vegan butter

Sauce

  1. Oven and Onions: Preheat oven to 350 degrees F. Add vegan butter and onions to a medium frying pan on medium heat. Cook, stirring frequently, until onions soften (about 5 minutes).

  3. Add Liquids: Combine milk and broth. Add in 1/4-1/3 cup increments, whisking between additions to prevent clumping. Continue whisking until smooth.

Assembly and Baking

  1. First Layer: Grease an 8-inch (20 cm) square baking dish with vegan butter. Layer 1/3 of the potatoes across the bottom in an uneven pattern with holes to allow the sauce to drip through. Cover with 1/3 of the sauce.

  4. Bake uncovered: Uncover and bake for an additional 30 minutes or until potatoes are golden brown and tender.
  5. Broil: Broil on high for 3-4 minutes to form a golden crust on top. Remove from the oven and let cool for 10-15 minutes before serving.

Notes

While it can be tempting to add extra onion or garlic to this recipe, the flavors are very delicate and can easily overpower when added in excess. I recommend making this recipe as written the first time.

*Important: Use a silicone-coated whisk for pans with non-stick coating to prevent scratching the pan.

Storage: Store in an airtight container in the refrigerator for up to 3 days. Reheat in an oven-safe baking dish at 350 degrees F ( 175 C) until heated through.

Double this recipe if using a 13 x 9 inch baking dish. You can use the "2x" button in the top right of the recipe card to convert the measurements for you!

Substitutions

  • Vegan - make sure to use vegetable broth
  • Flour - instead of tapioca or cornstarch, you can use gluten-free 1-to-1 style flour or regular wheat flour. With starch, the sauce texture is more gooey. With flour, the texture is smooth like a traditional gravy. Most of my taste testers and I preferred starch. One taste tester preferred gluten-free flour.

This recipe is naturally gluten-free and dairy-free as written.
