The base is made from cooked potatoes that are smashed flat, brushed with butter, seasoned, and baked until golden and crisp. Once the base is prebaked it receives a quick finish with sauce, cheese and toppings so the cheese bubbles and the edges turn beautifully brown. Serve with a simple green salad for dinner, or cut into wedges for a fun appetizer.

How to Make Baked Potato Pizza

  1. Preheat the oven to 180°C (356°F) fan.
  2. Prepare the pan: Remove the base from a 24 cm (9.5 in) springform pan and place the ring on a piece of parchment paper. Brush the parchment with 1 tablespoon of melted butter to prevent sticking.
  3. Form the potato base: Place the cooked potatoes in the pan and smash them flat with a burger press (or the back of a spoon) to form an even disc. Pour the remaining melted butter over the potatoes and spread it evenly. Season with oregano, sea salt and black pepper.
  4. Pre-bake the potato disc for 20–25 minutes, until the top begins to brown and the edges are golden.
  5. Remove the ring from the pan, leaving the potato disc on the parchment. Top with tomato sauce, diced red onion, shredded mozzarella and pepperoni.
  6. Bake for 10 minutes at 180°C (356°F), then increase the oven to 220°C (428°F) fan and continue baking for another 8–10 minutes until the cheese is bubbly and golden.
  7. Finish: Carefully loosen the pizza from the parchment with a spatula, top with fresh basil, slice and serve warm.

Tips for Success

  • Grease the parchment thoroughly to prevent sticking and help release the potato base cleanly.
  • Wet or oil the burger press (or spoon) to avoid the potatoes sticking while you smash them.
  • Pat the potatoes dry if they are overly moist so the base will crisp better in the oven.
  • Customize toppings to suit your taste—add vegetables, different cheeses, or cured meats.

Possible Variations

  • Potato base: Instead of smashing, slice potatoes thin and layer them slightly overlapping in a single circular layer for a different texture.
  • Oil swap: Use olive oil instead of butter for a lighter or dairy-free option.
  • Cheese options: Try cheddar, Gouda, Fontina, burrata or Pecorino for varied flavor profiles.
  • Base alternatives: Use regular pizza dough and top with sliced potatoes if you prefer a traditional crust.
  • Sauce: Swap tomato sauce for mascarpone, cream cheese or pesto for a creamy or herby base.
  • Toppings: Ham, sausage, crispy bacon, mushrooms, peppers, artichokes, olives, or an egg added near the end of baking all work well.

Best Served With

  • Parmesan garlic bread or other crusty bread
  • Simple green salad with lemon vinaigrette
  • Light antipasto or prosciutto and melon
  • Roasted or steamed vegetables

How to Store Leftovers

Store any leftover pizza in an airtight container in the refrigerator and enjoy within 2–3 days. Reheat on a baking sheet in a 100°C (212°F) oven for 10–15 minutes until warmed through to preserve crispness.

FAQs

Why prebake the potato base?

Pre-baking crisps the surface, browns the edges and helps the base hold its shape when toppings are added.

What if I don’t have a springform pan?

Flatten the potatoes on a parchment-lined baking sheet or round tray, trim the edges into a disc, use the trimmings to fill the center and press again to form an even base.

Can I serve the pizza cold?

Yes. It’s tasty hot or cold, though the texture will be best when served warm.

Can I make it ahead?

Yes. Bake the potato base, cool it, then add toppings and refrigerate covered. Bake for about 30 minutes before serving to reheat and melt the cheese.

How do I reheat?

Reheat in a low oven (100°C / 212°F) for 10–15 minutes until warmed through, or at a higher temperature briefly to refresh the crisp edges.
