This oven baked 4-ingredients pepperoni pizza potatoes recipe is straight out of my childhood, when my younger brother would come home from school absolutely starving and raid the fridge. One afternoon he layered sliced potatoes with jarred pizza sauce, shredded mozzarella, and pepperoni in a glass casserole dish, baked it until bubbly, and it honestly changed how I think about after-school (and weeknight) comfort food. It tastes like a cross between loaded potato skins and a pan pizza, but with just four basic ingredients you probably already have on hand. It’s simple, filling, and perfect for busy days when you want something cozy without a lot of fuss or cleanup.
Serve these pepperoni pizza potatoes straight from the glass casserole dish with a simple green salad or steamed broccoli to balance the richness. Garlic bread or breadsticks are great if you’re feeding a hungry crowd and want to stretch the meal a bit. A side of extra warm pizza sauce for dipping makes it feel even more like takeout pizza night. For drinks, keep it casual with iced tea, lemonade, or a cold beer for the adults. This dish also works well as a game-day appetizer—just cut the potato rounds a bit smaller and let everyone scoop from the pan.
Oven Baked 4-Ingredient Pepperoni Pizza Potatoes
Servings: 4

Ingredients
2 pounds russet or Yukon gold potatoes, sliced into 1/4-inch rounds
1 1/2 cups jarred pizza sauce
2 cups shredded mozzarella cheese
1 cup sliced pepperoni (about 3–4 ounces)
Directions
Preheat your oven to 400°F (200°C). Lightly grease a 9x13-inch glass casserole dish with a bit of oil or nonstick spray so the potatoes don’t stick.
Scrub the potatoes well and pat them dry. Leave the skins on for extra texture. Slice the potatoes into 1/4-inch rounds, trying to keep them as even as possible so they cook at the same rate.
Spread a thin layer of pizza sauce (about 1/4 cup) over the bottom of the glass casserole dish. This helps keep the first layer of potatoes from sticking and adds flavor all the way through.
Arrange the potato slices in a single, slightly overlapping layer over the sauce. It’s okay if they’re not perfect—this is a very forgiving, after-school-style recipe.
Spoon and spread about half of the remaining pizza sauce over the potatoes. Sprinkle with half of the shredded mozzarella, then scatter about half of the pepperoni slices on top.
Repeat with a second layer: arrange the rest of the potato slices on top, then spread the remaining pizza sauce over them. Finish with the remaining mozzarella and the rest of the pepperoni, making sure some pepperoni is on top so it can get crispy in the oven.
Cover the dish tightly with foil and bake for 25 minutes to help the potatoes steam and soften. This step keeps the top from burning before the potatoes are tender.
After 25 minutes, carefully remove the foil. Return the uncovered dish to the oven and bake for another 20–25 minutes, or until the potatoes are tender when pierced with a fork, the cheese is fully melted, and the pepperoni on top is starting to curl and crisp at the edges.
For extra color and crispiness, switch the oven to broil for 2–3 minutes at the end, watching closely so the cheese doesn’t burn. You want golden, bubbly cheese and nicely crisp pepperoni.
Remove the casserole from the oven and let it rest for about 5–10 minutes. This helps the layers set up a bit so it’s easier to scoop and the potatoes aren’t lava-hot. Serve warm straight from the glass dish, scooping out big spoonfuls of potato rounds, melted mozzarella, and crispy pepperoni.
Variations & Tips
If you want to keep the spirit of the original 4-ingredient after-school dish but play around a bit, you can swap the type of potato: Yukon golds get creamy and buttery, while russets give you a slightly fluffier texture. Try using a thicker pizza sauce if you like a more intense flavor, or a thinner one if you want it to soak into the potatoes more. For a different vibe, use mini pepperoni so every bite gets a little crisp edge, or cut regular pepperoni into halves or quarters to spread it more evenly. You can also change up the cheese by using part-skim mozzarella for a lighter version or a low-moisture whole milk mozzarella for extra gooeyness. To prep ahead on a busy workday, slice the potatoes in the morning and store them in cold water in the fridge, then drain and pat dry before assembling and baking at dinnertime. Leftovers reheat well in the oven or air fryer—just warm until the potatoes are hot and the pepperoni re-crisps. If you ever want to stretch the recipe for more people, you can add a fifth ingredient like sliced black olives or a sprinkle of Italian seasoning, but the original four-ingredient version is nostalgic, fast, and perfect when you want maximum comfort with minimum effort.
