Southern 3-ingredient buttery potato squares are the kind of simple, old-fashioned potluck dish that disappears fast because they turn humble pantry staples into something rich, cozy, and crowd-pleasing. These are perfect when you need an easy side for a church supper, family gathering, or weeknight meal, and that buttery golden top with those crisp little edges gives them that comforting Southern casserole feel without a long ingredient list.
Serve these potato squares alongside baked ham, fried chicken, meatloaf, or pork chops for a hearty supper. They also fit right in on a holiday table with green beans, glazed carrots, or a crisp side salad to balance the richness, and a little applesauce or cranberry sauce on the side can make the whole plate feel extra homey.
Southern 3-Ingredient Buttery Potato Squares
Servings: 8
Ingredients
1 package refrigerated shredded hash brown potatoes, about 20 ounces
Directions
1. Preheat the oven to 375°F and line an 8x8-inch baking pan with foil, then lightly grease the foil so the potato squares lift out easily after baking.
2. In a large mixing bowl, stir together the shredded hash browns, melted butter, and biscuit baking mix until everything is evenly combined and the potatoes are fully coated.
3. Press the mixture firmly and evenly into the prepared pan, smoothing the top so it bakes into neat squares with crisp edges.
4. Bake for 40 to 45 minutes, or until the top is golden brown and the edges are crisp and buttery.
5. Let the pan cool for 10 minutes, then lift the potatoes out using the foil, cut into squares, and serve warm.
Variations & Tips
For extra flavor: If you want to dress these up a little while keeping the same easy method, you can add a pinch of black pepper, garlic powder, or onion powder. It goes beyond the basic 3 ingredients, but it is a nice trick when you want a little more savory flavor for supper.
For crispier edges: Press the mixture firmly into the pan and do not spread it too thick. If your family loves those crunchy corner pieces, bake a few extra minutes until the edges deepen to a richer golden brown.
For picky eaters: Cut the baked potatoes into small bite-size squares and serve them with ketchup or ranch on the side. Little ones and cautious eaters often enjoy them more when they feel like finger food.
For make-ahead ease: You can mix and press the potato mixture into the pan a few hours ahead, cover it, and refrigerate until baking time. That makes these especially handy for holiday meals, covered-dish suppers, and busy school nights.
For easy lifting and slicing: Let the baked potatoes rest before cutting so the squares hold together better. Using foil in the pan makes cleanup easy and helps you lift the whole batch out in one piece for neater serving.
