Golden Onion Potato Yogurt Squares from One Bowl

Print recipe below

Every so often, a simple, comforting dish comes along that feels like it was made for any meal of the day. This potato and onion yogurt bake hits that spot perfectly. It’s easy to put together—all from one bowl—and bakes into golden squares packed with cheesy, savory flavor. The combination of coarsely grated potatoes with a touch of yogurt keeps it moist and tender inside while developing a crisp, golden crust on the outside. Adding cheddar gives it just the right sharpness without overpowering the dish.

This recipe works well when you’re looking for hands-off cooking without sacrificing taste. One thing I found is that squeezing out as much moisture as possible from the potatoes really helps the squares hold together and get that perfect crust without getting soggy. The balance between yogurt and flour creates a light batter that bakes up fluffy rather than dense. It’s a comforting, versatile dish—you could serve it for breakfast, a simple lunch, or a side to dinner—and it’s reliable every time once you get the basic steps down.

Ingredients

3 medium potatoes, coarsely grated (about 1 pound / 450 g)
1 medium onion, finely chopped (about 1 cup / 150 g)
3 large eggs
3/4 cup (180 ml) plain yogurt
3/4 cup (90 g) all-purpose flour
1 teaspoon baking powder
3/4 cup (85 g) shredded cheddar cheese, divided
2 tablespoons (30 ml) olive oil
Salt and black pepper, to taste

Ingredient Notes

Potatoes are the star here—using starchy varieties like Russets or Yukon Golds works best because they get crispier when baked. The key step is draining excess moisture by squeezing the grated potatoes tightly to avoid sogginess. Plain yogurt keeps the batter tender and adds a slight tang without making the dish heavy—whole-milk yogurt is ideal, but low-fat works too. Baking powder helps create a light rise, especially since the mixture doesn’t contain yeast or additional leaveners. Cheddar cheese brings sharpness and richness, but you can swap it for mozzarella or a mild cheese if you prefer a subtler taste.

Kitchen Tools Needed

Box grater or food processor with grater attachment
Fine mesh strainer or clean kitchen towel (for squeezing potatoes)
Large mixing bowl
Whisk or fork
8-inch (20 cm) square baking pan
Rubber spatula or spoon for folding ingredients
Oven

Step-by-Step Instructions

Preheat your oven to 400°F (200°C). Line an 8-inch (20 cm) square baking pan with parchment paper or lightly grease it with oil to prevent sticking.
Grate the potatoes coarsely. Place the grated potatoes in a clean kitchen towel or fine mesh strainer and squeeze out as much moisture as you can—this step is crucial to avoid a soggy bake.
In a large bowl, whisk together the eggs, yogurt, flour, baking powder, olive oil, salt, and plenty of black pepper until you have a smooth batter.
Fold in the squeezed potatoes, finely chopped onion, and half of the shredded cheddar cheese until evenly combined. The batter will be quite thick.
Spread the mixture evenly into your prepared baking pan, smoothing the surface with a spatula. Sprinkle the remaining cheddar cheese on top.
Bake in the center of the oven for 35 to 40 minutes. The squares should be deeply golden brown on top and cooked through—the edges will crisp up nicely, and a toothpick inserted in the middle should come out clean.
Allow the bake to cool in the pan for about 10 minutes before slicing into squares. This resting time helps the squares set and makes cutting easier.

Pro Tips

Be generous when squeezing the potatoes dry—any leftover water will make the bake soggy.
Use sharp cheddar for better flavor, but if your cheddar is mild, consider adding a pinch of smoked paprika or cayenne for an extra kick.
Don’t overcrowd the baking pan; spreading the mixture evenly ensures even cooking and beautiful browning.
Let the bake cool slightly before cutting to prevent it from falling apart.
If you want a crispier top, switch to broil for the last 1-2 minutes but watch carefully to avoid burning.

Common Mistakes

Not squeezing the grated potatoes well enough, resulting in a wet, mushy texture.
Overmixing the batter, which can make the bake dense instead of light.
Using a baking pan that’s too large or too small, causing uneven thickness and inconsistent baking times.
Cutting the squares immediately after baking when still too hot, leading to crumbling.
Skipping the baking powder — it helps give the squares a better lift and texture.

Variations

Swap cheddar for Gruyère or Parmesan for a nuttier flavor profile.
Add herbs like chopped chives, parsley, or thyme to brighten up the dish.
Stir in cooked bacon bits or sautéed mushrooms for a heartier, savory twist.
Use Greek yogurt instead of plain yogurt for a creamier finish and slightly tangier taste.

Serving Suggestions

These golden squares are lovely served warm or at room temperature. They pair well with a simple green salad for lunch or alongside roasted vegetables for dinner. You can also serve them with a dollop of sour cream or a spoonful of your favorite chutney or sauce. Because they hold their shape nicely, they’re great for brunch buffets or packed for picnics.

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 3 days. The potatoes and cheese hold up well, but the squares are best enjoyed fresh or within a few days for optimal texture.

Reheating Tips

Reheat the squares in a preheated oven at 350°F (175°C) for 10 to 15 minutes, or until warmed through. Oven reheating helps keep the exterior crisp instead of getting soggy like in a microwave.

Frequently Asked Questions

Can I use other types of cheese?
Yes. Cheddar gives a nice sharp flavor, but you can use mozzarella for milder flavor or a combination like Parmesan and Gruyère for extra depth.

Can I make this ahead of time?
Absolutely. The batter can be assembled and kept in the fridge for a couple of hours before baking. Leftovers store well and can be reheated easily.

Is it possible to make this gluten-free?
Yes. Substitute the all-purpose flour with a gluten-free flour blend. The texture might be slightly different but still delicious.

Can I add other vegetables?
You can stir in finely grated carrot or zucchini (well squeezed) for extra nutrition, but keep the overall moisture balanced to avoid sogginess.

What if I don’t have yogurt?
You can substitute sour cream or buttermilk, which offer a similar tang and moisture, though the texture may vary slightly.
