Baked Spinach Casserole : Creamy, Cheesy, and Comforting


  • Author: BeauCollier

Description

Tender spinach, creamy ricotta, melty mozzarella, and a golden Parmesan-breadcrumb topping—this casserole is comfort food at its finest. Serve as a side or a vegetarian main; it’s simple, flavorful, and always a crowd-pleaser.


Ingredients

Scale
  • 2 tbsp olive oil or butter

  • 1 small onion, finely chopped

  • 2 cloves garlic, minced

  • 1 lb fresh spinach (or 1 package frozen, thawed and squeezed dry)

  • 1 cup ricotta cheese (whole-milk or part-skim)

  • 1 cup shredded mozzarella cheese (reserve 1/4 cup for topping if desired)

  • 1/2 cup grated Parmesan cheese

  • 2 large eggs

  • Salt & pepper, to taste

  • 1/2 cup breadcrumbs (plain or panko)

  • Optional: pinch of nutmeg, for warmth and depth


Instructions

  1. Preheat & Prep
    Preheat oven to 375°F (190°C). Grease an 8×8-inch baking dish with butter, oil, or cooking spray.

  2. Sauté the Aromatics
    In a large skillet, heat olive oil or butter over medium heat. Add onion and a pinch of salt; cook until soft, about 5 minutes. Add garlic and cook 30–60 seconds until fragrant.

  3. Wilt the Spinach

    • Fresh: Add all spinach to skillet and cook 3–4 minutes until wilted.

    • Frozen: Ensure it’s well-drained, then warm through 1–2 minutes.

  4. Mix the Cheesy Base
    In a large bowl, combine ricotta, 3/4 cup mozzarella, Parmesan, eggs, salt, pepper, and nutmeg. Stir until smooth.

  5. Combine Spinach & Cheese
    Fold the sautéed spinach and onion mixture into the cheese mixture. Taste and adjust seasoning.

  6. Top & Bake
    Spread mixture evenly in prepared baking dish. Sprinkle remaining mozzarella and breadcrumbs on top. Drizzle a little olive oil for extra golden crunch. Bake 25–30 minutes until bubbly and golden.

  7. Rest & Serve
    Let cool 5–10 minutes before slicing. Serve alongside roasted chicken, salmon, or enjoy as a vegetarian main with salad or bread.

Notes

  • Squeeze the spinach dry! Extra moisture = soggy casserole.

  • Use fresh grated cheese for creamier texture.

  • Optional extras: sautéed mushrooms, bell peppers, or artichokes for added depth.

  • Make ahead: Assemble, refrigerate up to 24 hours, then top and bake.
