Creamy overnight oats with grated apple, lemon, and nuts—invented by a Swiss physician as a nutritious breakfast. Light, fresh, and naturally wholesome.
Birchermüesli was created around 1900 by Swiss physician Maximilian Bircher-Benner for patients at his Zurich sanatorium as a nutritious, easily digestible meal. The original recipe was radical for its time—raw oats, grated apple, lemon juice, and condensed milk—at a period when cooked food dominated medical nutrition. Over decades it evolved into the familiar overnight oats preparation using yogurt or cream, and became one of Switzerland's greatest contributions to global breakfast culture. Swiss Birchermüesli is wetter, fruitier, and less processed than the dry muesli associated with breakfast cereals elsewhere.
Serves 2
Combine the rolled oats, milk, and lemon juice in a medium bowl. Stir well and leave to soak for at least 30 minutes at room temperature, or cover and refrigerate overnight.
Stir the yogurt and honey or maple syrup into the soaked oats until well combined. The mixture should be creamy and thick.
Grate one apple (skin on) directly into the oat mixture and stir immediately to prevent browning. The apple juice will further soften the oats and add natural sweetness.
Fold in the raisins, half the hazelnuts, and half the almonds. If using chia seeds, stir them in now. Cover and refrigerate for at least 1 hour (or overnight) for best results.
Divide between two bowls. Top with the diced apple, fresh berries, and the remaining toasted nuts. Drizzle with extra honey if desired. Serve chilled.
Grating the apple last-minute and stirring immediately prevents oxidation and browning.
Full-fat yogurt gives the creamiest result; Greek yogurt makes it thicker.
Overnight soaking yields the creamiest oats—the 30-minute version is good but overnight is better.
In Switzerland, Birchermüesli is often made in large batches and kept for 2–3 days.
Replace milk with oat milk or almond milk for a dairy-free version.
Add 1 tablespoon of flaxseeds and 1 teaspoon of cinnamon for extra nutrition.
Use orange juice instead of lemon for a sweeter, more tropical flavor.
Store prepared Birchermüesli without the fresh fruit toppings in an airtight container in the refrigerator for up to 3 days. Add fresh fruit and nuts just before serving.
Dr. Maximilian Bircher-Benner created this recipe around 1900 at his Zurich Lebendige Kraft sanatorium. Inspired by a shepherd he met in the Alps who ate a similar raw oat porridge, he developed the recipe as a health food for his patients. It spread across Europe through the 20th century and is now consumed globally as a healthy breakfast staple.
They are very similar. Birchermüesli is the Swiss original and typically features fresh grated apple, lemon juice, and a higher proportion of fresh fruit and nuts. Modern overnight oats are inspired by it but vary widely in preparation.
