  • 1 Tbsp unsalted butter 14 g
  • 4 cloves garlic minced
  • 1 8-oz package cream cheese 226 g

Instructions

    Cup of Yum
  1. Prep: Preheat oven to 350℉ (176℃).
  2. Thaw: Transfer frozen spinach to a sieve or colander and run warm water over it to thaw. Squeeze as much water as you can out of the spinach.
  3. Garlic: Melt butter in a large skillet over medium heat, then add garlic. Cook until it begins to brown and become fragrant.
  4. Cheese: Stir in cream cheese until it becomes warm and soft. Stir in gruyere and parmesan until melted, then stir in spinach.
  5. Topping: Stir together fried onions and panko.
  6. Assemble: Spoon spinach mixture into a 9x3'' (or similar) casserole dish. Top with fried onion mixture. (Optionally spray the top lightly with oil to promote browning.)
  7. Bake: Bake on the center rack for 30 to 40 minutes, or until bubbling and top is golden brown.
