Potato Babka

Hearty Belarusian potato casserole with crisp edges and sweet caramelized onions.

Prep Time:20 minCook Time:60 minTotal Time:80 minServings:6Difficulty:Medium

This Potato Babka is my warm, homey take on a classic Belarusian potato casserole — all those nostalgic flavors of grated potatoes, sweet caramelized onions and maybe a little smoked bacon. It bakes until the edges are crisp and the center is creamy, the kind of dish that invites conversation and second helpings.

It’s straightforward to make and utterly rewarding: you grate, squeeze, mix and bake, then finish with a smear of sour cream and a scattering of dill. Serve it alongside pickles or a simple salad for a satisfying family meal that nods to Belarusian tradition.

Directions

  1. 1
    Buttered ceramic baking dish with potatoes and onions nearby

    Preheat the oven to 375°F and butter a 9x9-inch (or similar) baking dish.

  2. 2
    Grated potatoes draining in a kitchen towel over a bowl

    Grate the potatoes on the coarse side of a box grater into a large bowl. As they grate, place them on a clean kitchen towel and squeeze out as much liquid as possible; save the liquid briefly and let any starch settle to the bottom if you want to use it for extra binding.

  3. 3
    Chopped onion and thin onion slices on a wooden board

    Grate or finely chop one onion and set aside. Thinly slice the second onion for caramelizing.

  4. 4
    Bacon, caramelized onions and garlic cooking in a skillet

    In a skillet over medium heat, cook the diced bacon until crisp. Remove with a slotted spoon and reserve the fat. In the same skillet add 1 tbsp butter and the sliced onion; cook slowly until deep golden and sweet, about 12–15 minutes. Stir in the minced garlic during the last minute and remove from heat.

  5. 5
    Grated potato mixture with bacon, eggs, flour and sour cream

    In a large bowl combine the squeezed grated potatoes, grated onion, cooked bacon, eggs, flour, sour cream, salt and pepper. Stir until evenly mixed; the mixture should hold together when pressed.

  6. 6
    Potato babka mixture layered with caramelized onions and butter

    Spoon half the potato mixture into the prepared dish, pressing down to form an even layer. Scatter half the caramelized onions over it, then spread the remaining potato mixture on top and finish with the remaining onions and small knobs of the remaining 2 tbsp butter.

  7. 7
    Golden baked potato babka in a ceramic dish

    Bake uncovered for 45–55 minutes, or until the top is golden brown and the center is set. If the top is browning too quickly, tent loosely with foil for the last 10–15 minutes.

  8. 8
    A square slice cut from rested potato babka

    Let the babka rest for 10 minutes so it firms up, then run a knife around the edge and invert onto a serving platter or slice directly from the dish.

  9. 9

    Serve warm with a dollop of sour cream and a sprinkling of fresh dill. Accompany with pickled cucumbers or a crisp green salad for contrast.

    Leftovers keep well refrigerated and are delightful reheated in a skillet to restore the crisp edges.

Ingredients

  • Russet potatoes, peeled:3 lb
  • Onion, large:2 pieces
  • Smoked bacon, diced:6 oz
  • Large eggs:3 pieces
  • All-purpose flour:1/2 cup
  • Sour cream:1/2 cup
  • Butter:3 tbsp
  • Vegetable oil:2 tbsp
  • Salt:1 tsp
  • Black pepper:1 tsp
  • Fresh dill, chopped:2 tbsp
  • Garlic cloves, minced:2 pieces

Tips & Notes

  • Squeeze grated potatoes very well to avoid a watery babka—too much liquid prevents browning.
  • Caramelize onions slowly over medium-low heat for the sweetest flavor; patience pays off.
  • If you prefer vegetarian, omit the bacon and add a touch more butter for richness or substitute smoked paprika.
  • Reheat slices in a skillet over medium heat instead of the microwave to keep the crust crisp.
