Ingredients
  

  • 2 cups onion diced, 1 really large onion
  • 1/2 stick unsalted butter (1/4 cup)
  • 1 leek green top removed, diced or sliced
  • 2 cloves garlic minced
  • 1/4 cup gluten free flour
  • 1/8 tsp. nutmeg
  • 1/2 cup heavy whipping cream
  • 1 cup half-and-half
  • 24 oz. frozen chopped spinach thawed with all moisture pressed out
  • 3/4 cup Parmesan cheese shredded
  • 1/2 cup Gruyere cheese shredded
  • 1 1/2 tsp. sea salt or kosher salt
  • 1/4 tsp. black pepper

Instructions
 

  • Melt butter in a large skillet over medium heat.
  • Add onions and leeks and sauté about 5 minutes until tender.
  • Add garlic and cook about 1 minutes longer—until fragrant, but don’t scorch the garlic or it will become bitter.
  • Add the flour and nutmeg.
  • Stir and cook an additional minute.
  • Add the cream and half-and-half and stir constantly until mixture is thickened.
  • Add salt and pepper.
  • Stir in 1/3 cup freshly grated Parmesan cheese.
  • Squeeze out as much water from spinach as possible and add to cream mixture. (I used a potato masher to press out the water).
  • Stir pressed spinach into cheese mixture.
  • Prepare a 9x13” glass baking dish by spraying with olive oil cooking spray.
  • Add spinach mixture.
  • Sprinkle remaining Parmesan cheese and 1/2 cup freshly grated Gruyere cheese.
  • Cover with foil. Bake at 350° about 30 minutes or until hot and bubbly.
