Gyros

1 medium onion, chopped fine
2 pounds ground lamb, beef or combo thereof
1 tbls finely minced garlic
1 tbls dried marjoram
1 tbls dried ground rosemary
2 tsp kosher salt
1/2 tsp black pepper

Preheat the oven to 325 degrees F. Process the onion in the food processor for 10 to 15 seconds and turn out into the center of a tea towel. Gather up the ends of the towel and squeeze until almost all of the juice is removed. Discard juice. Return the onion to the food processor and add the lamb, garlic, marjoram, rosemary, salt and pepper and process until it is a fine paste, approximately 1 minutes. Stop the processor as needed to scrape down sides of bowl. Place the loaf pan into a water bath and bake for 60-75 minutes or until the mixture reaches 165-170 degrees. Remove from the oven and drain off any fat. Place the loaf pan on a cooling rack and place a brick wrapped in aluminum foil directly on the surface of the meat and allow to sit for 15-20 minutes, until the internal temperature reached 175 degrees.

If desired, slice thin and brown in oil. Serve with Tzatziki sauce.
