Ingredients

  • 1 package gnocchi 2 cups
  • 5 tbsp unsalted butter
  • 3 tbsp AP flour
  • 1 ½ cups whole milk
  • 1 large yellow onion sliced thinly
  • 2 tsp granulated sugar
  • 1 tsp Worcestershire sauce
  • 1 ½ tsp fresh thyme
  • ½ cup beef broth
  • 1 cup mozzarella shredded
  • Salt / Pepper

Instructions

  1. Preheat oven to 400 F. In a large skillet, melt 2 tbsp butter over medium-high heat. Once melted, add the onions. Let the onions sauté for about 2 minutes. Next add the sugar, Worcestershire sauce, thyme, salt and pepper. Continue to cook the onions for another minute or 2 and then add the beef broth. Scraping the bottom of the skillet, making sure everything is well combined, turn the heat to simmer. Stir the onions, to keep from burning, until golden brown, about 20 minutes. Set aside.
  2. Cook gnocchi in salted water. Drain and add to a 9x13 baking dish.
  3. In a saucepan, melt remaining butter over medium heat. Next add flour and whisk until a roux forms, about 1 minute. Pour in milk and whisk until thickened, about 5 minutes. Add salt and pepper to taste.
  4. Place onions over gnocchi. Pour the white sauce over the onions, followed by the mozzarella. Bake 10 to 15 minutes or until cheese has turned golden brown. Garnish with fresh thyme.
