Francis’s lesson plan

Every class begins with a YesChef original documentary film. In Francis Mallman's Story, go on an adventure to the wilderness of Argentina to visit Francis on his secluded island in Patagonia. Experience his passion for open-fire cooking and how it shaped his food, philosophy and beliefs. Discover his roots and life journey, as you meet the people he has inspired, and the food that defines him.

It’s Sunday on the island, and Francis and his team are preparing for a barbecue feast.  In this short documentary, Francis takes you into his Patagonian world to discover the true meaning of the sacred ritual that defines Argentine culture: chorizos, steaks, ribs, sweetbreads, salads, free-flowing red wine, and great company.

Learn from Francis in his open-air kitchen, the quincho, as he shares two of his seven signature cooking methods utilizing live-fire: hanging and slow-roasting ingredients over heat and the rescoldo, burning vegetables in ashes. Don't miss this unique opportunity to watch and learn these ancient cooking techniques.

Francis teaches how to make two empanada recipes: baked meat empanadas with onion, eggs, and olives; and fried cheese and onion empanadas. This family-friendly dish is easy to make for the kids or to serve at a party.

Francis brings life to vegan cooking and teaches his daughters’ absolute favorite Christmas dish: a platter overflowing with a colorful assortment of seasonal vegetables. Learn how to perfectly choose, cut, and cook fresh vegetables on the plancha.

Learn how to make one of Argentina’s favorite comfort foods with Italian roots, the milanesa. While the milanesa is traditionally pounded thin and deep fried, Francis prefers a thick cut of tenderloin cooked bleu, or extra rare, on the chapa grill.

While there are many ways to cook fried and scrambled eggs, Francis has his preferences. Learn Francis’s simple and delicious tricks and techniques of making the perfect fried and scrambled eggs.

A symbol of the Andes, potatoes are very special to Francis. Over the last 50 years, he has developed a unique tuber devotion. So, buy yourself a big bag of papas and learn from Francis nine different ways of how to cook the mighty potato.

Francis shares this favorite tortilla española recipe, a classic Argentine dish with Spanish roots. While it’s possible to use any onions available, Francis’s secret is combining three types of onions for sweetness.

Since construction workers don’t have much time on their lunch break, occasionally they’ll build a quick fire, slap a piece of chapa on top of the makeshift parrilla, and grill a thin piece of steak. Then, top it all off with bacon, avocado, and crispy sweet potato chips.

Revuelto gramajo is a Buenos Aires classic, most commonly found across the country in neighborhood bodegones (Argentine cantinas). Francis puts his own spin on this scrambler-hash hybrid that resembles an omelette, but stays true to its original ingredients: eggs, ham, and fried shoestring potatoes.

From Patagonia to Paris, Francis transports you to Café de Flore, one of his favorite places in France known for its oeufs à la coque, soft-boiled eggs, a sophisticated yet simple breakfast that Mallmann regularly makes at home for his children.

All you need is three carrots, a handful of thyme, a bit of cream, olive oil, and a cast iron pan to make Francis’s latest hit vegetarian recipe. You’ve never tasted carrots quite like these.

This dish is a bestseller at Francis’s restaurant for a reason. Learn how to prepare this vegetarian spin on the humble classic by using the mighty eggplant. Francis teaches how to char, coat, and pan fry the eggplant with clarified butter.

Francis invented the infiernillo or “little hell” oven about 20 years ago. Today, he proclaims his love for Patagonian trout as he fires up his small inferno to teach you how to make freshly-caught salt-crusted trout.

Francis teaches how to make two different panqueque desserts on the plancha that make him “very happy”: Dulce de Leche Pancakes and Granny Smith Apple Pancakes. These thin crepes are usually served for dessert, but also great for a sweet breakfast.

Francis teaches how to make one of his favorite desserts. Learn how to make this refreshing dish and add it to your dessert repertoire. It may seem simple, but it’s loaded with supremely fresh and complex flavors and textures.

This fish stew is proven to nourish the body and soul. Francis teaches how to truly build and layer complex flavors with simple ingredients. Hint: The true taste of the chupín comes from the bones and the head of the fish, plus a lot of love and care.

Francis brings us to one of his favorite places on the island, near a beautiful waterfall, to cook trout fillets sandwiched between two crispy potato cakes. Learn techniques like the proper way to fillet a fish.

No pots or pans are needed for this recipe. Join Francis on a hike in the wild outdoors, on the edge of a beautiful waterfall where he improvises a simple meal with only sticks and fish.

A simple dessert that only calls for 3 ingredients: Pears, salt, and dulce de leche. “When you cook a pear like this, all of the humidity of the pear stays inside so it’s very, very delicious,” Francis says.

Francis and his brother Carlos go on a nature walk to a beautiful waterfall. There, he whips up one of his favorite no-fuss Gaucho-inspired camping meals: skirt steak and burnt bread sandwich.

Homemade Dulce de LecheIt’s hard to find a dessert in Argentina that doesn’t contain dulce de leche. Francis’s sous chef, Ricki Motta, teaches how to make this classic favorite that will sweeten up your life.

Clarified butter is the secret weapon Francis uses to make his food crispy and luxurious. Ricki Motta, Francis’s sous chef, teaches how to make this golden glory.
