German Savory Potato Cake (Kartoffelkuchen)

The scent of rosemary and garlic, mingling with the earthy aroma of baked potatoes, instantly transports me back to my grandmother’s kitchen in Bavaria. Oma’s Kartoffelkuchen was a staple, a comforting dish that magically appeared after a day spent playing in the crisp autumn air. It wasn’t just food; it was a warm hug on a plate, a taste of home that lingered long after the last bite. Every time I bake this savory potato cake, I feel a little closer to her, sharing a piece of our family history with every slice.

• 1 medium onion, diced
• 175 g butter (or 175 g margarine), divided
• 50 g ham, in small cubes

• Dry breadcrumbs, for dusting the pan
• 3-4 sprigs fresh rosemary
• 1 garlic clove, chopped finely, more to taste
• 250 g sour cream (or 250 g creme fraiche)
• 5-6 eggs (medium-large)
• Additional sour cream, to garnish
• Rosemary, to garnish

Equipment Needed

• Large pot
• Potato ricer or masher
• Large bowl
• Frying pan
• Spatula
• Rectangular rimmed baking tin (approximately 32 x 39 cm) or rimmed cookie sheet
• Whisk

Instructions

1. Begin by peeling and washing all the potatoes.
2. Divide the potatoes into two equal portions. Cut one portion into halves, place them in salted water, and cook for about 20 minutes, or until they are soft enough to mash.
3. Shred the remaining raw potatoes using a grater or food processor.
4. Place 50 grams of the butter in a heated pan.
5. Sauté the diced onion and the ham cubes together in the melted butter until the onion is translucent and the ham is lightly browned. This will take approximately 5-8 minutes.
6. Add the shredded potato to the pan, and cook it together with the onion and ham, turning it over occasionally with a spatula, for about 5-8 minutes. The potatoes should soften slightly but not brown significantly.
7. Remove the shredded potato mixture from the pan and set aside to cool.
8. Drain the cooked potatoes that have been simmering in water and mash them thoroughly using a potato ricer or a potato masher.
9. In a large bowl, mix the mashed potatoes together with the remaining 125 grams of butter, the flour, and salt & pepper to taste. Knead the ingredients together until a smooth, pliable dough forms.
10. Grease a large rectangular rimmed baking tin, approximately 32 x 39 cm in size, using the butter wrapper or some extra butter or oil. Then, dust the greased pan with dry breadcrumbs, ensuring an even coating. This will prevent the potato cake from sticking.
11. Press the potato dough evenly into the prepared pan, forming a crust. Ensure that the dough covers the entire base of the pan and extends slightly up the sides to create a rim.
12. Strip the rosemary leaves from their stems and chop them finely.
13. In a separate bowl, whisk together the eggs, chopped rosemary, finely chopped garlic (adjust to your taste), sour cream (or crème fraiche), and caraway seeds (optional).
14. Combine the egg mixture with the shredded potato mixture, mixing thoroughly to ensure all ingredients are evenly distributed.
15. Season the mixture with salt & pepper to taste.
16. Spread the potato and egg mixture evenly over the potato pastry in the prepared baking tin.
17. Place the baking tin on a lower rack in the oven, which has been preheated to around 200°C (392°F). Bake for approximately 50 minutes, or until the potato cake is golden brown and set. A toothpick inserted into the center should come out clean.
18. Once baked, cool the potato cake slightly in the pan for about 5-10 minutes.
19. Cut the slightly cooled potato cake into 16 squares.
20. Garnish each square with a small dollop of sour cream and a sprig of fresh rosemary, if desired.

Expert Tips & Tricks

• For a richer flavor, use browned butter instead of regular melted butter in both the dough and the shredded potato mixture.
• If you don’t have fresh rosemary, dried rosemary can be used, but use sparingly, as it has a more concentrated flavor. About 1-2 teaspoons of dried rosemary should suffice.
• To ensure even cooking, use a baking stone beneath the baking tin.
• If the top of the potato cake starts to brown too quickly during baking, tent it loosely with aluminum foil.
• Make ahead tip: The potato dough can be prepared a day in advance and stored in the refrigerator. Let it come to room temperature slightly before pressing it into the pan.

Serving & Storage Suggestions

Serve the Kartoffelkuchen warm or at room temperature. It’s delicious as an appetizer, a side dish, or even a light lunch when paired with a fresh green salad. Leftovers should be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. While it can be frozen, the texture of the potatoes may change slightly upon thawing. To freeze, cut the cake into individual squares and wrap them tightly in plastic wrap before placing them in a freezer bag. Reheat directly from frozen in the oven.

FAQs (Frequently Asked Questions)

Q: Can I use different types of potatoes?
A: Starchy potatoes like Russets or Yukon Golds work best for this recipe because they create a light and fluffy texture. Waxy potatoes may result in a denser cake.

Q: Can I prepare the entire cake ahead of time?
A: Yes, you can assemble the entire cake and store it in the refrigerator for up to 24 hours before baking. Add a few extra minutes to the baking time to ensure it’s heated through.

Q: What if I don’t have a rectangular baking tin?
A: A round cake pan or even a large skillet can be used as a substitute. Adjust the baking time accordingly, checking for doneness with a toothpick.

Q: How do I prevent the bottom of the cake from becoming soggy?
A: Ensure that the potato dough is pressed firmly and evenly into the pan. Dusting the greased pan with breadcrumbs also helps create a barrier against moisture.

Q: Can I use milk instead of sour cream?
A: While milk can be used as a substitute, the sour cream adds a richness and tanginess that enhances the flavor. Crème fraiche is a good alternative if you don’t have sour cream on hand.
