This Creamy Spinach Casserole is a deliciously rich and cheesy side dish that’s perfect for holiday dinners, potlucks, or weeknight meals. Tender spinach is combined with a creamy sauce, cheeses, and subtle seasonings, then baked until bubbly and golden on top — a classic comfort-food favorite.
Ingredients
- 1 lb (450 g) fresh spinach, washed and chopped (or 1 (10 oz / 280 g) package frozen spinach, thawed and drained)
- 1 cup (240 ml) sour cream
- 1/2 cup (120 ml) mayonnaise
- 1/2 cup (50 g) grated Parmesan cheese
- 1 cup (115 g) shredded cheddar cheese (or mozzarella for a milder flavor)
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/4 tsp nutmeg (optional, enhances spinach flavor)
- 1/2 cup (50 g) breadcrumbs (optional, for a crunchy topping)
Instructions
1. Preheat Oven:
Preheat your oven to 350°F (175°C) and lightly grease a 9×9-inch (or similar) baking dish.
2. Prepare Spinach:
- Fresh spinach: Sauté with a small amount of olive oil or butter until wilted, then drain excess liquid.
- Frozen spinach: Make sure it is fully thawed and squeezed dry to prevent watery casserole.
3. Make the Creamy Mixture:
In a large bowl, combine sour cream, mayonnaise, Parmesan, shredded cheese, chopped onion, garlic, salt, pepper, and nutmeg. Stir in the prepared spinach until fully coated.
4. Assemble the Casserole:
Transfer the spinach mixture to the prepared baking dish. Sprinkle breadcrumbs and a little extra cheese on top if desired.
5. Bake:
Bake uncovered for 25–30 minutes, until the casserole is bubbly and the top is lightly golden.
6. Serve:
Allow to cool slightly before serving. Pairs beautifully with roasted meats, poultry, or holiday mains.
Tips for Perfect Creamy Spinach Casserole
- Avoid watery casserole: Drain cooked spinach thoroughly. Excess liquid can make the casserole runny.
- Cheese choice: Use a mix of sharp cheddar and creamy cheeses for depth of flavor.
- Make ahead: Prepare the casserole ahead of time, cover, and refrigerate; bake when ready.
- Texture: For extra creaminess, add a splash of cream or milk to the mixture.
Variations
- Bacon Spinach Casserole: Stir in crumbled cooked bacon for smoky flavor.
- Mushroom Spinach Casserole: Add sautéed mushrooms for extra depth.
- Italian Twist: Use mozzarella, Parmesan, and Italian seasoning; top with marinara drizzle.
- Low-Carb Option: Omit breadcrumbs or use almond flour for topping.
