Ingredients

Instructions

  1. Step 1: Preheat your oven to 425°F (220°C) and set aside an 8×11 inch casserole dish.
  2. Step 2: In a large pan, heat the olive oil over medium heat. Add the chopped onion and shredded potatoes, frying for about 10 minutes until slightly browned.
  3. Step 3: Transfer half of the browned hashbrowns to a large bowl. Add the vegan cheese sauce, all the seasonings (minced garlic, garlic powder, onion powder, smoked paprika, oregano), and half of the vegan cheese. Season with salt and pepper and mix well.
  4. Step 4: Spread this mixture evenly into the casserole dish. Top with the remaining browned hashbrowns and sprinkle the rest of the vegan cheese over the top.

Tips & Variations

  • You can substitute smoked paprika with regular paprika for a milder flavor or add a pinch of cayenne for heat.
  • For extra crispiness, spread the top layer thinly so it browns beautifully in the oven.
  • If you prefer, swap the vegan cheese for your favorite non-dairy cheese alternative or homemade nut-based cheese.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm the casserole in the oven at 350°F (175°C) until heated through and crispy on top, about 15–20 minutes.
