Introduction

This creamy spinach casserole is a comforting side dish that combines rich cheeses and flavorful seasonings with tender spinach. It’s easy to prepare and bakes to a golden, bubbly perfection—ideal for family dinners or holiday gatherings.

The quiche slice is accompanied by fresh, bright green avocado slices on the side. A silver fork lies next to the quiche on the plate. The background is a white marbled surface with a piece of quiche and a burnt orange cloth slightly out of focus. photo taken with an iphone --ar 4:5 --v 7

Ingredients

2 (10 oz) packages frozen spinach, thawed and drained
1 cup sour cream
1/2 cup cream cheese, softened
1/2 cup grated Parmesan cheese
1/2 cup shredded mozzarella cheese
1/4 cup breadcrumbs
2 cloves garlic, minced
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/4 teaspoon ground nutmeg
Salt and pepper to taste
1 tablespoon olive oil (for greasing)
Fresh parsley for garnish (optional)

Instructions

Step 1: Preheat your oven to 350°F (175°C) and grease a 9×9-inch baking dish with the olive oil.
Step 2: In a large mixing bowl, combine the thawed and drained spinach, sour cream, cream cheese, Parmesan, mozzarella, minced garlic, garlic powder, onion powder, nutmeg, salt, and pepper. Stir until well combined.
Step 3: Transfer the spinach mixture into the prepared baking dish and spread it evenly.
Step 4: Sprinkle the breadcrumbs evenly over the top of the spinach mixture to create a crispy topping.
Step 5: Bake in the preheated oven for 25–30 minutes, or until the casserole is bubbly and the top is golden brown.
Step 6: Remove from oven and garnish with fresh parsley before serving, if desired.

Tips & Variations

For extra flavor, try adding a pinch of crushed red pepper flakes or substituting mozzarella with cheddar cheese.
Use fresh spinach sautéed and drained if you prefer, but be sure to remove excess moisture to avoid a watery casserole.
To make it gluten-free, replace the breadcrumbs with gluten-free breadcrumbs or crushed nuts.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and warm in a 350°F (175°C) oven for about 15 minutes or until heated through. You can also microwave individual portions until hot.

FAQs

Can I use fresh spinach instead of frozen?

Yes, fresh spinach can be used. Sauté it until wilted and then drain well to remove excess moisture before combining it with the other ingredients.

Can this casserole be made ahead of time?

Absolutely. Prepare the casserole up to the baking step, then cover and refrigerate for up to 24 hours before baking. Add an extra 5 minutes to the baking time if baked cold from the fridge.
