Ingredients
Instructions
- Prep the spinach. Thaw frozen spinach completely and squeeze out as much liquid as possible using a clean kitchen towel or paper towels. If using fresh spinach, wilt it in a pan, then drain and squeeze dry.
- Make the mixture. Preheat the oven to 375°F (190°C). In a large bowl, beat the cream cheese until smooth. Mix in the eggs, sour cream (or yogurt), garlic, salt, pepper, nutmeg, and protein powder if using. Stir in the mozzarella, Parmesan, and squeezed spinach until well combined.
- Assemble. Transfer the mixture to a greased 8×8 or 9×9-inch baking dish. Smooth the top and sprinkle with extra mozzarella or Parmesan.
- Bake and serve. Bake 20–25 minutes until the top is golden and the center is set. Let rest 5 minutes before serving.
Notes & 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.
Variations & serving ideas
- 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.
- Spinach artichoke style: Add 1 cup chopped artichoke hearts for a classic dip-inspired bake.
- Extra cheesy: Increase the mozzarella and top with an extra layer of cheese before baking.
- Bacon spinach bake: Stir in 4–5 slices of cooked crumbled bacon.
- Mushroom version: Sauté mushrooms and fold them into the mixture for extra depth.
Storage
- Refrigerator: Up to 4 days (Store covered)
- Freezer: Up to 2 months (Freeze in portions for easy reheating)
- Reheat: Oven or microwave (Cover to keep moisture; add a splash of cream if needed)
