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.
