Pizzaiola roughly translates to “in pizza-style.” This version of pizzaiola is a casserole made with layers of potato, tomato sauce, and cheese. It is a comforting and delicious dish that is sure to be a favorite.


Units Scale
  • 4 cups of prepared tomato sauce
  • 3 lbs of potatoes
  • 2 cups ricotta cheese
  • 1 1/2 cups grated mozzarella
  • 1 1/2 cup grated cheddar cheese
  • 1/2 tsp of salt and pepper, to taste


  1. Thinly slice the potatoes. Aim to have them as thin as possible, as the dish will cook faster if the potato slices are around 1/8″ thick.
  2. Mix the ricotta with 1 cup of mozzarella and 1 cup of cheddar. The rest of the grated cheese will go on top of the casserole.
  3. Grease a medium-sized baking dish or medium-sized slow cooker to prevent sticking. Depending on how deep the dish is, you can make 2 or 3 layers. 
  4. Start by covering the bottom of the dish with potatoes. Overlap them to form a solid base. Lightly season the potatoes with salt and pepper.
  5. Cover the potatoes with sauce, then dollop on a layer of the ricotta and grated cheese mixture. This should use up 1/3 of the sauce and cheese for a deep dish (like a slow cooker), or 1/2 of the sauce and cheese for a shallow dish (like a baking pan).
  6. Repeat the layers of potatoes, sauce, and cheese, until it is all used up. Finish the casserole with a final layer of potatoes and top with the remaining grated cheese (1/2 cup mozzarella and 1/2 cup of cheddar).
  7. Baking instructions: Cover the baking dish with tin foil and bake at 400 F for 40 minutes. Remove the tinfoil and bake for another 15-30 minutes, until the potatoes are cooked and the cheese is bubbling.
  8. Slow cooker instructions: set the slow cooker on low for 6-8 hours or on high for 3-4 hours, until the potatoes are well cooked.


  • I like using my rotating mandolin to make nice thin slices of potato.
