Keto German-Style Fried Potatoes from Radishes
It sounds odd at first: radishes as a fried-potato substitute? In fact it is one of the oldest tricks in low-carb cooking, and for good reason. When pan-fried, radishes lose almost all of their peppery bite, their texture turns soft and slightly mealy, and the pink hue fades to a gentle golden brown. Per serving: 3 g net carbs, 22 g fat and 9 g protein.

Preparation
Wash 400 g of radishes, trim off the greens and, depending on size, halve or quarter them. Very small radishes can stay whole, what matters is a uniform size. In a heavy skillet, heat 1 tbsp of ghee, render 80 g of diced bacon until crisp and remove it from the pan. Add 1 tbsp of butter, then arrange the radishes cut-side down. Important: do not crowd the pan. The radishes need 3 to 4 minutes of undisturbed heat so the cut surface can caramelize. Then turn them and fry for another 5 to 6 minutes, tossing every few minutes. After 6 minutes, add the thinly sliced white parts of the spring onions, season with salt and pepper. At the end, fold the bacon back in and serve sprinkled with the green parts of the spring onion.
Why do radishes work so well when fried?
Radishes contain mustard oils (glucosinolates) that account for their characteristic bite. These compounds are heat-sensitive: after just a few minutes in a hot pan, most of them break down. What is left is a mild, slightly sweet flavor with a hint of cabbage. In terms of texture, radishes turn softer when fried and develop a slightly mealy interior, not quite like a potato but closer than you might think. Per 100 g they provide only 2 g of net carbs, a fraction of what potatoes deliver.

Tips and little tricks
The cut surface caramelizes better than the skin, so place halved or quartered radishes cut-side down in the pan. The skin gives them structure and keeps them from falling apart. For a more classic flavor, add 1/2 tsp of caraway seeds, which deepens the fried-potato note. A garlic clove in thin slices, added in the last 2 minutes, also pairs nicely. For a main course, fried radishes work beautifully with two sunny-side-up eggs, or as a side with a bratwurst plate. To make it fancy, stir in 1 tbsp of cream at the end and add a touch of mustard.
Tips for radish fried potatoes
- Halve or quarter the radishes depending on size, keeping them uniform.
- Place them in the pan cut-side down.
- Do not move them for the first 3 to 4 minutes so they brown.
- Bacon and caraway deliver the classic fried-potato note.
- For very sharp radishes, blanch briefly first to tame the bite.

FAQ
Do fried radishes really not taste sharp?
After 6 to 8 minutes in a hot pan the bite is largely gone. A faint savory note remains, but it is far removed from the raw, peppery flavor. Most people cannot identify the main ingredient on first taste.
Which type of radish works best?
Classic round, red radishes work best. Long white icicle radishes are often sharper and can turn slightly bitter when fried. Avoid very large, woody radishes, as they will not soften even with pan-frying.
Can I prep the radishes ahead?
Trimmed and halved radishes keep for 1 day in the fridge in a sealed container. Already fried radishes lose a lot of quality when reheated, so it is best to make them fresh.
