An overhead shot of a golden-brown vegan hashbrown casserole in a rustic ceramic baking dish, steam gently rising from its crispy, lightly caramelized top.

Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 190°C (375°F) and lightly grease your baking dish with a small amount of olive oil or line with parchment paper. Place your thawed hashbrowns in a large bowl, gently breaking up any clumps. If your hashbrowns still feel very wet, place them in a clean kitchen towel and gently squeeze out excess moisture - this will ensure your casserole gets nice and crispy on top.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Heat the olive oil in a medium skillet over medium heat. Add the diced onion and sauté for 5-7 minutes until soft and translucent. Add the minced garlic and cook for another 30 seconds until fragrant. Be careful not to burn the garlic as it can become bitter. Remove from heat and let cool slightly.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Drain and rinse your soaked cashews, then add them to a high-speed blender along with the plant milk, vegetable broth, nutritional yeast, tapioca starch, lemon juice, smoked paprika, garlic powder, onion powder, turmeric, salt, and pepper. Blend on high for 2-3 minutes until completely smooth and creamy. The cashews create the rich, creamy base that mimics traditional dairy in this recipe, while the nutritional yeast adds that quintessential "cheesy" flavor.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Add the cooked onion and garlic mixture to the blender and pulse a few times to incorporate, leaving some texture. Pour this cashew cheese sauce over the hashbrowns in the bowl. Add the chopped chives and gently fold everything together until the hashbrowns are evenly coated with the sauce. The starch in the potatoes will help bind with the cashew sauce as it bakes, creating a cohesive casserole.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Transfer the mixture to your prepared baking dish, spreading it out evenly. Sprinkle the panko breadcrumbs evenly across the top of the casserole. The breadcrumbs will toast in the oven, creating a deliciously crispy contrast to the creamy interior.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Bake uncovered in the preheated oven for 40-45 minutes, or until the top is golden brown and crispy, and the edges are bubbling. If the top begins to brown too quickly, loosely cover with aluminum foil and continue baking. You'll know it's ready when you can see the sauce bubbling around the edges and the top has a beautiful golden crust.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Remove from the oven and let the casserole rest for 10-15 minutes before serving. This resting time allows the casserole to set up properly, making it easier to serve in neat portions. Garnish with additional chopped chives and a light sprinkle of smoked paprika for color and flavor. Serve warm as a hearty breakfast dish or comforting side. The casserole can be refrigerated for up to 4 days or frozen for up to 3 months in an airtight container.</li></ol>

What ingredients are used in Vegan Hashbrown Casserole Recipe?

This dairy-free casserole combines frozen shredded hashbrowns with a creamy cashew cheese sauce made from soaked cashews, plant milk, nutritional yeast, and seasonings. Sautéed onions, garlic, herbs, and a crispy panko breadcrumb topping complete this comforting dish.

How to cook Vegan Hashbrown Casserole Recipe at home?

Learn how to cook Vegan Hashbrown Casserole by first creating a creamy cashew cheese sauce in your blender, then folding it with thawed hashbrowns and sautéed onions. Spread the mixture in a baking dish, top with panko breadcrumbs, and bake at 190°C for 40-45 minutes until golden and bubbling for a perfectly crispy exterior and creamy interior.

Can I make this hashbrown casserole ahead of time for a brunch gathering?

Absolutely! You can assemble the casserole up to 24 hours in advance and refrigerate (without the breadcrumb topping). Add the panko just before baking. You may need to add 5-10 minutes to the cooking time if baking straight from the refrigerator.

What can I substitute for cashews if I have a nut allergy?

For a nut-free version, replace cashews with silken tofu (300g) or sunflower seeds (soaked similar to cashews). White beans can also work as a base. These alternatives will create a creamy texture, though the flavour profile may vary slightly from the original recipe.

How do I ensure my hashbrown casserole gets crispy on top but stays creamy inside?

Removing excess moisture from thawed hashbrowns is key—pat them dry with kitchen towels. Allow your casserole to bake uncovered to develop that perfect crisp top, and don't skimp on the panko breadcrumbs. The 10-15 minute rest after baking helps set the creamy interior.
