THE CHEF: Douglas Katz

His Restaurants: Zhug, Amba and Provenance, all in Cleveland

What he is known for: bringing a farm-to-table made-from-scratch philosophy into his Cleveland eating scene over more than 20 years. The establishment of welcoming restaurants that are a go-to for special occasions. Making a variety of dishes that depend on a full spice cabinet.

WITH THREE popular Cleveland restaurants under his belt and another slated to open next year, Douglas Katz’s schedule is permanently packed—and has been ever since he entered professional kitchens at age 14. Needless to say, the chef knows a thing or two about cooking for a busy week.

Enjoy this frittata, it’s his very debut Slow Food Fast contribution. The dish is made from fresh herbs, wild mushrooms, and lots of Gruyere.

Apart from the basic ingredients, the most important ingredient is perseverance, Katz said. “You want the eggs to be custardy, so add cream or cheese for extra fat–and cook it slow and low so nothing dries out.”

The best part? On the following day, according to the chef, leftover frittata can be the perfect (and easy) lunch for your desk. “Grab a slice straight from the fridge or tuck it between some good bread and eat it as a sandwich,” he advised. However, the possibilities don’t stop there. You can wrap them in salsa inside microwaved tortillas from the office. “It makes a great taco,” he told me.
