Ingredients

For the Spinach Base

• 2 boxes frozen chopped spinach – The hearty, nutrient-rich base of the casserole
• 1/4 cup water – Helps cook and soften the spinach evenly
• 3 slices white bread, crusts removed, torn into pieces – Thickens the mixture and adds body
• 1/2 cup butter (1 stick) – Creates richness and signature Rockefeller flavor
• 1 teaspoon celery salt – Adds subtle savory depth
• 1 1/2 teaspoons Worcestershire sauce – Brings umami richness (use a halal-certified version)
• 1/4 teaspoon garlic salt – Enhances the overall flavor

For the Topping

• 2 tablespoons butter, melted – Helps crisp and brown the topping
• 1/2 cup coarse fresh bread crumbs – Creates that irresistible crunchy layer
• 1/2 cup grated Parmesan – Adds salty, nutty flavor and golden color

How to Make Spinach Rockefeller Casserole

Step 1: Preheat the Oven

Preheat your oven to 400ºF so it’s fully heated and ready when the casserole goes in.

Step 2: Cook the Spinach

In a medium saucepan, combine the frozen chopped spinach and 1/4 cup water. Cover with a lid and cook over medium heat for 10–15 minutes, stirring frequently to break up the spinach as it thaws and cooks. Do not drain the water—this moisture helps create the creamy texture of the dish.
Tip: Stir often to prevent sticking and ensure even cooking.

Step 3: Build the Creamy Mixture

Add the torn bread pieces, 1/2 cup butter, celery salt, Worcestershire sauce, and garlic salt to the spinach. Stir until the butter melts completely and everything is well combined. Let the mixture simmer gently for about 10 minutes, stirring frequently. The bread will break down and thicken the spinach into a rich, cohesive mixture.

Step 4: Prepare the Topping

In a small bowl, combine the melted 2 tablespoons butter, fresh bread crumbs, and grated Parmesan. Use a fork to mix until crumbly and evenly coated. This topping is what gives Spinach Rockefeller Casserole its signature crispy finish.

Step 5: Assemble the Casserole

Lightly butter a small round casserole dish. Spoon the spinach mixture into the dish and smooth the top evenly. Sprinkle the breadcrumb-Parmesan mixture over the spinach, covering it completely for even browning.

Step 6: Bake

Place the casserole in the center of the oven and bake for 15 minutes, or until the top is golden brown and the edges are bubbly. If you like extra crunch, broil for the last 1–2 minutes—but watch carefully to prevent burning.

Tips for Success

• Use fresh bread crumbs for the best texture and crispiness
• Do not drain the spinach cooking liquid—it’s essential for creaminess
• Taste the spinach mixture before baking and adjust seasoning if needed
• Let the casserole rest 5 minutes after baking so it sets slightly before serving

Equipment Needed

• Medium saucepan with lid
• Small mixing bowl
• Fork for mixing topping
• Small round casserole dish (an 8-inch dish works well)
• Oven mitts

Recipe Variations

• Extra Creamy Version: Stir in 2–3 tablespoons cream cheese before baking for added richness
• Cheesy Spinach Bake: Add shredded mozzarella or Swiss to the spinach mixture
• Low-Carb Option: Replace bread pieces with crushed pork rinds or almond flour and use low-carb breadcrumbs
• Herb-Infused Twist: Add a pinch of nutmeg or fresh thyme for subtle warmth

Serving Suggestions

Spinach Rockefeller Casserole pairs beautifully with roast beef, lamb, or baked chicken. It’s especially perfect for holiday spreads alongside mashed potatoes, roasted carrots, or dinner rolls. Garnish with a light sprinkle of extra Parmesan or chopped parsley before serving for an elegant touch.

FAQs

Can I make Spinach Rockefeller Casserole ahead of time?
Yes. Assemble the casserole up to a day in advance, cover, and refrigerate. Bake just before serving.
