Vegan Yule Log Recipe - also known as Bûche de Noël or Chocolate Roll Cake with Dairy-Free Cream Filling and Chocolate GanacheThis rich but healthy plant-based casserole recipe is a sample from Vegan Holiday Cooking by Kirsten Kaminski. We shared this cookbook before Christmas, with a sample recipe for Vegan Chocolate Yule Log Cake. But the relevance of Kirsten’s recipes carries into the New Year with comforting winter dishes and a full chapter for Easter!

The Easter chapter includes twists on old favorites, like Vegan Egg Salad, Dijon Scalloped Potatoes, Cinnamon Hot Cross Buns, and Spinach and Mushroom Alfredo Lasagna.

This cheesy plant-based casserole is actually in the Thanksgiving chapter, but we think you will love adding it to your regular plant-based repertoire. And it would be pretty good for Easter too!

Recipe type: Entree
Cuisine: American
Serves: 4 to 6 servings
Ingredients
Dairy-Free Cheese Sauce
  • 1 cup (150 g) cashews, soaked for 6 to 8 hours (or overnight)
  • 1½ cups (360 ml) almond or soy milk beverage
  • 1⁄4 cup (20 g) nutritional yeast
  • 1⁄2 teaspoon ground turmeric
  • 1⁄4 teaspoon salt
  • 1⁄8 teaspoon black pepper
Veggies
  • 2 medium sweet potatoes, peeled and diced
  • 1 small head cauliflower, chopped into small florets
  • 1 medium red onion, thinly sliced
  • 2 tablespoons (6 g) finely chopped fresh parsley, plus more as needed
Veggie Marinade
  • 1⁄2 cup (120 g) tahini or almond butter
  • 1⁄3 cup (80 ml) water
  • 1 tablespoon (16 g) Dijon mustard
  • 1 tablespoon (15 ml) apple cider vinegar
  • 1 teaspoon garlic powder
  • 1 teaspoon maple syrup
  • 1⁄4 teaspoon salt
  • 1⁄8 teaspoon black pepper
Instructions
  1. To make the dairy-free cheese sauce, drain the cashews and place them in a blender. Add the milk beverage, nutritional yeast, turmeric, salt, and black pepper and blend until the sauce is smooth.
  2. To make the veggies, preheat your oven to 400°F (200°C) and grease a 7x10–inch (18 x 25–cm) baking dish.
  3. While the oven is preheating, combine the sweet potatoes, cauliflower, onion, and parsley in a large bowl.
  4. To make the veggie marinade, whisk together the tahini or almond butter, water, mustard, vinegar, garlic powder, maple syrup, salt, and black pepper in a medium bowl until the marinade is smooth. Pour the marinade over the veggies and use your hands or a large spoon to coat them all.
  5. Transfer the veggies to the prepared baking dish and spread them out evenly. Pour the cheese sauce on top and make sure all the veggies are covered.
  6. Cover the casserole with foil or the lid and bake for 45 minutes. Uncover the casserole and bake for another 30 minutes, or until the veggies are soft and the top is golden brown.
  7. Let the casserole cool slightly and serve with additional parsley.
