Some recipes are inseparable from the place where they were born.

Chios Mastelo is one of them.

Fragrant with the unmistakable aroma of Chios mastiha, fresh citrus, herbs and slow-roasted lamb, this dish has long been the centerpiece of Sunday lunches, Easter celebrations and family gatherings across the island.

Unlike many festive recipes that rely on complex techniques, Mastelo is all about patience. Time, gentle heat and exceptional local ingredients transform a simple cut of lamb into an unforgettable feast.

Why Is It Called “Mastelo”?

The word Mastelo comes from the old Mediterranean word mastello, referring to a deep clay vessel or earthenware pot traditionally used for marinating and slow-cooking meat.

Across several Greek islands, particularly those influenced by Venetian trade, these clay pots became essential kitchen tools because they retained moisture and distributed heat evenly during long cooking.

In Chios, the name remained attached to the dish itself.

Over time, “Mastelo” no longer referred only to the pot—but to the slow-cooked lamb prepared inside it.

Today, the recipe remains one of the finest examples of traditional Chian home cooking.

The Aroma of Chios

No ingredient represents Chios better than mastiha.

Harvested exclusively on the southern part of the island, these crystal-like resin tears have flavored Greek cooking for centuries.

Combined with lemon zest, white wine and rosemary, mastiha gives this recipe an elegant aroma unlike any other Greek lamb dish.

As many Chian grandmothers say:

“Mastiha should whisper—not shout.”

Its fragrance should enhance the meat, never overpower it.

Authentic Chios Mastelo

Serves 4–6

Ingredients

• 1.5–2 kg (3½–4½ lb) lamb or young goat (shoulder or leg)
• 2 large onions, sliced
• 3–4 garlic cloves
• 1 glass dry white wine
• Juice of 2 lemons
• Zest of 1–2 lemons
• 1 sprig fresh rosemary
• A pinch of oregano
• Extra virgin olive oil
• Salt
• Freshly ground black pepper

The Secret Ingredient

• 4–5 tears of Chios mastiha
• A pinch of coarse salt (for grinding)

Crush the mastiha together with the coarse salt using a mortar and pestle.

This prevents it from sticking and turns it into a fine powder.

Instructions

Marinate the Meat

Place the lamb in a large bowl.

Add:

White wine
Lemon juice
Lemon zest
Garlic
Rosemary
Olive oil
Half of the ground mastiha

Cover and refrigerate overnight—or for at least 4–5 hours.

The slow marinade tenderizes the meat while allowing the delicate aromas to penetrate deeply.

Prepare the Baking Dish

Arrange the sliced onions on the bottom of a clay pot or Dutch oven.

Sprinkle with oregano and drizzle with olive oil.

Place the marinated meat on top together with all the marinade.

Scatter the remaining mastiha and a little extra lemon zest over the meat.

Slow Roast

Bake covered at 170°C (340°F) for approximately 3 hours, or until the meat becomes meltingly tender.

Remove the lid during the final 30–40 minutes to allow the lamb to develop a beautifully golden crust.

Grandmother’s Secrets

Mastiha should always be used sparingly.

Lemon zest is just as important as the lemon juice.

Slow cooking creates tenderness without drying the meat.

Generous olive oil is part of the recipe—not an extra ingredient.

Mastelo always tastes even better the following day.

Extra Cooking Tips

• Always grind the mastiha with coarse salt before using it.
• Marinate the meat overnight whenever possible.
• Use a clay pot or Dutch oven for the most authentic result.
• Finish uncovered for a beautifully caramelized crust.
• Allow the meat to rest for 15 minutes before serving.

What Is the Difference Between Chios Mastelo and Sifnos Mastelo?

Although they share the same name, these are two completely different traditional dishes.

Chios Mastelo

Prepared with lamb or young goat.
Flavored with Chios mastiha, lemon, white wine and herbs.
Slowly roasted in a clay pot or covered baking dish.
Rich in citrus aromas and Mediterranean herbs.
Traditionally enjoyed at Sunday family meals and festive gatherings.

Sifnos Mastelo

The famous Sifnos Mastelo is an Easter specialty.

It is traditionally cooked in the island’s distinctive clay mastelo pot using red wine, dill and plenty of spring onions. During Easter celebrations, the pot was often placed inside the communal wood-fired ovens after the Resurrection service, where the lamb cooked slowly overnight.

Despite sharing the same name, the flavor profile and ingredients are entirely different.

Frequently Asked Questions (FAQ)

1. Can I use goat instead of lamb?

Absolutely. Young goat is equally traditional and develops a wonderfully delicate flavor.

2. Can I prepare it without mastiha?

Yes, but it will no longer have the authentic Chian character that makes this recipe unique.

3. Why is the meat marinated overnight?

The marinade tenderizes the meat and allows the mastiha, citrus and herbs to infuse every bite.

4. Can I cook it in a regular roasting pan?

Yes, but a clay pot or Dutch oven produces the most authentic result by retaining moisture during the long cooking process.

5. Does Mastelo taste better the next day?

Yes. Like many traditional Greek slow-cooked dishes, its flavors become even richer after resting overnight.

A Dish That Carries the Soul of Chios

Chios Mastelo is far more than a slow-roasted lamb recipe.

It is a celebration of one of Greece’s most extraordinary ingredients —mastiha— and a reminder that the greatest traditional dishes are born from patience, local produce and the joy of gathering family around the table.

Every bite carries the fragrance of citrus groves, the warmth of wood-fired kitchens and the timeless hospitality of the island of Chios.
