Ingredients

  • 1 package gnocchi, fresh or defrosted 375-500 g or 13-16 ounces
  • 1/4 cup (22.5g) grated fresh Parmesan cheese
  • 1 tablespoon chopped parsley for garnish

White Cheese Sauce

  • 1 1/2 tablespoon butter salted or unsalted butter is fine
  • 2 tablespoon all purpose flour
  • 1 garlic cloves, minced (or 1/4 tsp garlic powder)
  • 1 teaspoon poultry seasoning or more to taste
  • 1/2 teaspoon salt (or to taste)
  • pinch black pepper
  • pinch nutmeg optional
  • 1 1/2 cup (375ml, 12 oz) milk, 2% or whole (1/4 cup of this can be light or heavy cream for extra richness)
  • 1 cup (83g) grated white cheese e.g. Gruyere, Fontina, Emmenthal, Monterey Jack, Provolone
  • 1/4 cup chopped green onion

Instructions

  • PREHEAT OVEN to 400F/204C. Spray a small 7-8 inch/18-20cm ovenproof baking dish with olive oil or cooking spray
  • BOIL GNOCCHI: Bring salted water to boil in medium saucepan. Put gnocchi in boiling water, bring water back to boil, and lower heat to med heat. Gently boil for 2 minutes. Drain gnocchi and set aside.
  • MAKE CHEESE SAUCE: Melt butter on medium heat in a medium or large saucepan. Add garlic and stir for 30 seconds. Add flour and seasonings, stirring for 2 minutes. Add milk (and cream if using), whisking until slightly thickened, about 4-5 minutes. Turn off heat. Stir in grated cheese until smooth sauce is formed. If too thick, add a bit more milk (but note that sauce will thicken further with baking and standing). Taste and adjust seasonings. Stir in gnocchi and green onions.
  • ASSEMBLE AND BAKE/BROIL: Spoon mixture into prepared gratin dish. Sprinkle 1/4 cup Parmesan cheese and chopped parsley over the surface. Bake for 7 minutes, then broil for 3 minutes to brown, watching to ensure it doesn't burn. Let stand for a few minutes (sauce will thicken more) and serve with toothpicks as an appetizer or as a side or main dish.

Notes
