When you mention ‘Osterlamm‘ in Switzerland, half the room will probably picture a cute sponge cake dusted with powdered sugar and shaped like a lamb. While it is certainly a sweet tradition, the real culinary hero of the holiday is not the cake. It’s the savoury, herb-crusted meat that brings everyone together. As the snow melts from the lower Alps and the meadows turn green, people’s appetites shift towards something substantial and celebratory.
While the Swiss are traditionally a nation of beef lovers, from dried meats to hearty stews, a special exception is made for this Sunday. The Easter lamb roast recipe is the undisputed king of the spring menu, offering a distinct, robust flavour profile worthy of a feast. Are you ready to skip the bakery and go straight to the butcher to prepare a seasonal celebration meal?
Then you’ve come to the right place! Prepare to be amazed as we unveil a time-honoured technique that will elevate your roast to the very zenith of the holiday season.
The Story Behind the Easter Lamb Roast Recipe
One of the most distinctive features of this holiday is that its date changes each year. Easter can fall in late March, when it is still cold and sometimes snowy, or at the end of April, when it is sunny and the flowers are in bloom.
The beauty of a great Easter lamb roast recipe is its versatility — it’s perfect for both scenarios. It is hearty enough for a cold day, yet the herbs give it a freshness that makes it perfect for a warm afternoon.
While the Swiss often opt for beef for their Sunday roasts throughout the rest of the year, the Easter lamb roast is a cherished exception to the rule. It marks a seasonal shift — here in Switzerland, the Easter date is considered when changing from winter to summer tyres.
However, preparation focuses less on heavy sauces and more on letting the quality of the meat shine through. Whether the weather dictates a cosy meal indoors or the first lunch on the terrace, this dish remains the anchor of the day.
Preparation steps
Step 1 – Tempering
Before you even think about the oven, take the meat out of the fridge. For a successful Easter lamb roast, the meat must be at room temperature. Leave it out for an hour to ensure the muscle fibres don’t go into ‘shock’ when they “hit” the heat.
Step 2 – The infusion
Preheat your oven to 220°C (430°F). Make small incisions all over the lamb using a sharp knife. Fill these pockets with garlic slivers and rosemary sprigs. This infuses flavour deep into the roast, ensuring that every slice of your Easter lamb roast is aromatic
Step 3 – The rub
Mix together olive oil, lemon juice, zest, chopped thyme and rosemary. Rub this mixture all over the lamb and season generously with salt and pepper. Place the lamb in a roasting tin, optionally on a bed of potatoes and onions.
Step 4 – The ‘low and slow’ roast.
This is the crucial step for tenderness. Put the lamb in the oven at 220°C (430°F) for just 20 minutes to sear the crust. Then, drop the temperature down to 160°C (320°F). Continue cooking gently. This lower temperature prevents the meat from tightening up. For a medium-rare result, calculate roughly 20–25 minutes per 500 g of meat (e.g. a 2 kg leg will take between 1 hour 20 minutes and 1 hour 40 minutes at this lower heat). Always check with a meat thermometer to be sure!
Step 5 – Rest and serve.
Once the internal temperature reaches 55°C (medium rare), remove the meat from the oven. Cover loosely with foil and leave to rest for 20 minutes. This allows the juices to settle, ensuring a moist cut.

Pairing: Fermento 21 Ventuno Honey Beer
Now, let’s talk about what to put in your glass. Since the Easter weather is so unpredictable, we have two recommendations to accompany your lamb roast.
If it’s unseasonably warm and sunny, that might be the case if Easter is at late April, a crisp pils is the perfect choice. Our Golden Breeze is ideal: its high carbonation and bitterness cleanse the palate of the lamb’s fat, making it refreshing.
However, if it’s cool outside — as it often is — or if you simply want a flavour profile that can stand up to the roast, you must try Fermento 21 Ventuno honey beer. This sophisticated yet comforting pairing is sure to impress. The amber-gold colour and honey notes mirror the caramelised crust of the lamb. Its strong alcohol content (6.9%) and body match the intensity of the garlic and herbs, while the hint of sweetness provides a beautiful contrast to the savoury meat. It warms you from the inside, making it the perfect choice for a cosy Easter feast.
