Ingredients

  • 2 cups (160 g) old-fashioned rolled oats, not steel-cut oats
  • 1 1/2 cups (360 ml) 2% milk, plus optional extra for serving
  • 1 1/2 cups (360 g) plain 2% Greek yogurt
  • 2 medium apples (about 300 g after coring), coarsely grated
  • 1 tablespoon fresh lemon juice
  • 1 tablespoon honey
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/8 teaspoon fine salt
  • 1 cup (150 g) fresh blueberries, washed and dried
  • 1 cup (150 g) sliced fresh strawberries, washed and dried
  • 1/3 cup (30 g) sliced almonds

Instructions

  1. Prepare clean containers. Set out a large mixing bowl and four covered breakfast containers or jars, each with enough room for roughly 1 1/2 cups plus toppings. Clear space in the refrigerator before mixing; this is a chilled dish and should not soak on the counter.
  2. Combine the creamy base. Whisk together the milk, yogurt, honey, vanilla, cinnamon and salt until evenly mixed. Scrape the bottom of the bowl so the honey does not remain in a sticky layer. The base should look smooth apart from the cinnamon flecks.
  3. Grate the apples. Wash and core the apples, leaving the peel on if you like its texture. Coarsely grate them and immediately toss with the lemon juice. Include the apple juices rather than squeezing them out, since they contribute moisture and flavor to the oats.
  4. Mix in the oats and apple. Fold the rolled oats and grated apple into the yogurt mixture until all the flakes are coated. Check the bottom and edges for dry pockets. The mixture will look a little looser now than it will after the oats absorb liquid overnight.
  5. Portion and refrigerate. Divide the mixture evenly among the four containers and cover. Refrigerate for at least 8 hours at 40°F (4°C) or below. The total recipe time includes this overnight rest; no stovetop cooking is required.
  6. Prepare the toppings separately. Wash and dry the berries thoroughly and refrigerate them in a separate covered container. Keep the almonds dry and separate. If using delicate berries, prepare them in the morning instead of the night before for the best texture.
  7. Check the morning consistency. Stir one portion from the bottom. If it feels too stiff, mix in a little extra milk, 1 tablespoon at a time. If it seems loose, stir again and allow a few minutes for the texture to settle before adding toppings.
  8. Finish each bowl. Divide the blueberries and strawberries among the four portions and sprinkle each with one-quarter of the almonds. Add the nuts just before eating so they stay crisp. The nutrition estimate includes these measured toppings, not additional honey or milk.
  9. Serve cold and store the rest. Eat directly from the container or spoon into a bowl. Keep any unserved portions refrigerated and use within 3 days. Label make-ahead containers with the preparation date so they are easy to rotate through the refrigerator.

These Swiss-inspired overnight oats combine grated apple, creamy yogurt and rolled oats for a breakfast that is ready when you are. Fresh berries add brightness and sliced almonds provide crunch. A little lemon keeps the apple flavor lively, while cinnamon and vanilla make the bowl feel gently sweet without a heavy topping.

The idea is inspired by Bircher-style muesli, adapted here into four practical refrigerator portions. Instead of cooking the oats, you let them soften in milk and yogurt overnight. Keep the berries and almonds separate until serving so the fruit stays fresh and the nuts keep their texture. The mixture is intentionally thick; stir in a small splash of milk in the morning if you prefer a looser bowl. This version is a home adaptation rather than a reproduction of an original historical recipe.

Timing and texture

Allow 20 minutes of hands-on preparation plus at least 8 hours of refrigeration: approximately 8 hours 20 minutes total. Old-fashioned rolled oats produce a pleasant texture; quick oats become softer, and steel-cut oats will not soften in the same way with this method.

Allergen-aware substitutions

Use certified gluten-free oats when needed and check every ingredient. For a nut-free variation, omit the almonds and avoid ingredients with unsuitable cross-contact warnings. Dairy-free milk and yogurt change the protein content and texture; select versions appropriate for your needs.

Make-ahead tips

Prepare the base in individual portions and leave the toppings separate. Use fresh dairy within its use-by date and clean utensils. Keep refrigerated, including during transport with an ice pack, and use within 3 days. Do not leave the jars at room temperature overnight.

Frequently asked questions

Can I heat these oats?

You can gently warm an individual portion if you prefer, adding milk to loosen it, but the yogurt may separate slightly. Add fresh berries and almonds afterward. This recipe is designed and timed for serving cold.

Can I use frozen berries?

Yes, but follow the package handling directions. Some frozen berries require cooking before eating; cool them before adding. Thawed fruit releases extra juice, so add it at serving time rather than thinning the base too early.
