What You’ll Need (Ingredients and Key Roles)

• Fresh spinach: 900 g (2 lbs) fresh, or 450 g (1 lb) frozen, thawed. Wilts down beautifully for a vibrant green base. Opt for organic spinach when possible for the best flavor.
• Unsalted butter: 45 g (3 tablespoons). Essential for sautéing and creating the rich sauce base.
• Shallots: 2 medium (about 100g), finely minced. Adds a subtle sweetness and aromatic depth.
• Garlic: 3 cloves, minced. An essential aromatic for robust flavor.
• All-purpose flour: 30 g (1/4 cup). To thicken the cream into a silky sauce.
• Heavy cream: 360 ml (1.5 cups). Creates a luxurious, rich sauce (or half-and-half for a slightly lighter touch if that’s what you have on hand).
• Water: 120 ml (0.5 cup). Helps achieve the perfect sauce consistency without being too heavy.
• Freshly grated nutmeg: 1/4 teaspoon. A classic pairing with spinach and cream for warmth and subtle spice.
• Ground black pepper: 1/2 teaspoon. For a touch of heat and flavor.
• Sea salt: 1/2 teaspoon, or to taste. Enhances all the flavors.
• Gruyère cheese: 100 g (1 cup), freshly grated. Adds a nutty, complex flavor and amazing melt (Cheddar or Monterey Jack also work if that’s what’s in your cheese drawer). Look for quality cheeses from your local deli.
• Parmesan cheese: 50 g (1/2 cup), freshly grated, plus extra for topping. For a salty, umami kick and golden topping.
• Preserved lemon: 1 half (about 25g), pulp removed, rind finely diced. Adds a bright, tangy, and salty complexity.
• Panko breadcrumbs: 60 g (1 cup). Creates an irresistibly crisp topping.
• Za’atar spice blend: 1 tablespoon. Adds an earthy, tangy, and aromatic Middle Eastern flair.
• Ground sumac: 1 teaspoon. Contributes a bright, citrusy note to the topping.
• Extra virgin olive oil: 2 tablespoons, plus extra for drizzling. Helps crisp the breadcrumbs and adds a finishing touch.
• Fresh mint leaves: 1/4 cup, roughly chopped, for garnish. Provides a vibrant, fresh contrast.

Step-by-Step Cooking Method

1. Prep the Spinach: If using fresh spinach, blanch it in boiling water for 1-2 minutes until wilted. Immediately transfer to an ice bath to stop cooking, then drain very well. Wring out as much liquid as possible using a clean kitchen towel; this is crucial to prevent a watery spinach gratin. Roughly chop the dry spinach. If using frozen spinach, simply thaw completely and wring out all excess liquid.
2. Make the Cream Sauce: In a medium saucepan or Dutch oven, melt 30 g (2 tablespoons) of butter over medium heat. Add the finely minced shallots and cook until softened and translucent, about 3-5 minutes. Add the minced garlic and cook for another minute until fragrant, being careful not to brown. Sprinkle the flour over the mixture and stir constantly for 1 minute to form a roux; if your roux seems too thick, a splash of water or cream will loosen it up. Gradually whisk in the heavy cream and water until smooth. Bring to a gentle simmer, whisking occasionally, until thickened, about 5-7 minutes. Remove from heat. Stir in the freshly grated nutmeg, ground black pepper, and sea salt. Add the grated Gruyère and 50 g (1/2 cup) Parmesan, stirring until the cheeses are fully melted and the sauce is smooth and creamy.
3. Combine and Bake: Preheat the oven to 190°C (375°F). Fold the finely diced preserved lemon and the squeezed, chopped spinach into the rich cheese sauce until well combined. My kids absolutely love this easy spinach gratin recipe, especially with the crunchy za’atar topping. Lightly grease a 2-liter (2-quart) gratin dish, like my favorite ceramic oval one, with the remaining 15 g (1 tablespoon) of butter. Transfer the spinach mixture into the prepared dish, spreading it evenly. In a small bowl, combine the panko breadcrumbs, za’atar, and sumac. Drizzle with 2 tablespoons of olive oil and mix until coated. Sprinkle this seasoned crumb mixture evenly over the spinach, optionally adding extra Parmesan. Bake for 25-30 minutes, or until the gratin is bubbly around the edges and the topping is golden brown and crisp. Remove from the oven and let rest for 5-10 minutes, allowing the gratin to set slightly before serving. Don’t skip squeezing the spinach; it’s crucial for a thick, creamy gratin. A watery spinach gratin recipe needs that step for success.
