Ingredients
Scale
For the Casserole
- 3 cups fresh spinach, chopped
- 3 cups cooked potatoes, diced or mashed (optional: Yukon Gold or Russet)
- 1 cup shredded Monterey Jack cheese
- ½ cup grated Parmesan cheese
- 1 cup heavy cream
- ½ cup sour cream
- 3 tbsp unsalted butter, melted
- 2 cloves garlic, minced
- ½ tsp salt
- ¼ tsp black pepper
- ¼ tsp nutmeg (optional)
For the Topping
- ½ cup shredded Monterey Jack or Parmesan cheese
- 1–2 tbsp butter, cut into small pieces
- Fresh parsley, chopped for garnish
Instructions
- Prepare the oven and dish: Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish to prevent sticking and ensure easy cleanup.
- Combine ingredients: In a large bowl, mix together the cooked potatoes (if using), chopped fresh spinach, heavy cream, sour cream, shredded Monterey Jack, grated Parmesan, melted butter, minced garlic, salt, black pepper, and nutmeg until you achieve a creamy and well-blended mixture.
- Transfer to baking dish: Pour the casserole mixture into the prepared baking dish, spreading it evenly and smoothing the top for an even bake.
- Add topping: Sprinkle the remaining shredded Monterey Jack or Parmesan cheese on top, then dot with small pieces of butter to enhance browning and flavor.
- Bake: Place the dish in the oven and bake for 25–30 minutes until the casserole is bubbly and the top turns a beautiful golden color.
- Optional broil: For an extra golden and crispy crust, broil the casserole for 1–2 minutes at the end of baking, watching carefully to avoid burning.
- Garnish and serve: Remove from the oven, sprinkle with fresh chopped parsley for color and freshness, then serve warm as a decadent side dish.
Notes
- Potatoes are optional but add a creamy, hearty texture to the casserole.
- Nutmeg is optional but adds a warm, subtle spice that complements the cheese and spinach.
- Can be prepared ahead and refrigerated; bake just before serving for best results.
- Leftovers reheat well in a 350°F (175°C) oven until warmed through to maintain texture.
- Pairs wonderfully with steak, roasted chicken, or seafood for an indulgent meal.
