Health notes

  • High protein: Cheese, eggs, and optional protein powder deliver a solid boost.
  • Low carb: No flour or breadcrumbs — just spinach and a creamy base.

Key element — squeeze the spinach well

If using frozen spinach, thaw and squeeze out as much liquid as possible. Excess moisture will make the bake watery instead of creamy.

Ingredients

Spinach bake

  • 16 oz (450g) frozen spinach, thawed and well drained (or 1 lb fresh spinach, wilted and drained)
  • 8 oz (225g) cream cheese, softened
  • 1 cup shredded mozzarella cheese
  • ½ cup grated Parmesan cheese
  • ½ cup sour cream or Greek yogurt
  • 2 large eggs
  • 1–2 scoops unflavored or garlic protein powder (optional, for extra protein)
  • 2 garlic cloves, minced
  • ½ tsp salt
  • ¼ tsp black pepper
  • ¼ tsp nutmeg (optional)
  • Extra mozzarella or Parmesan for topping

Swaps

  • Higher protein: Add an extra egg white or more protein powder.
  • Dairy-free: Use dairy-free cream cheese, yogurt, and cheese alternatives.
  • Extra veggies: Stir in chopped artichoke hearts or sautéed mushrooms.
  • Spicy: Add a pinch of red pepper flakes or diced jalapeño.

Instructions

Pro tips

  • Squeeze the spinach very well — this is the most important step for a creamy (not watery) bake.
  • Room-temperature cream cheese mixes more smoothly.
  • For extra browning, broil for the last 1–2 minutes (watch carefully).
  • This reheats well and is excellent for meal prep.
  • Serve as a side with chicken, steak, or fish, or enjoy on its own.
