Creamy Spinach Gratin Ingredients
For the Gratin
• Olive Oil – Provides fat for sautéing aromatic leeks; avocado oil is a great substitute for a flavorless option.
• Frozen Chopped Spinach (12 ounces, thawed and squeezed dry) – The star of this creamy spinach dish; ensure it’s well-drained to avoid a watery texture.
• Leek (2 tablespoons, finely chopped) – Adds a touch of sweetness; feel free to swap with green onions or shallots for a different flavor.
• Garlic (1 small clove, pressed) – Provides an aromatic foundation; adjust based on your preference for intensity.
• Dried Thyme – Infuses an earthy flavor into your gratin; Italian seasoning can work in a pinch.
• Grated Nutmeg – Adds warmth and depth to the creamy sauce; freshly grated is always best.
• Sea Salt & Black Pepper – Essential for enhancing flavors; adjust amounts to suit your taste.
For the Cheesy Base
• Mascarpone Cheese (3 ounces, softened) – Creates the luscious creamy base; cream cheese is a suitable alternative with a different texture.
• Gruyère Cheese (⅓ cup, shredded, divided) – Brings a nutty, savory flavor; substitute with Fontina or white cheddar if desired.
• Parmesan Cheese (3 tablespoons, grated, divided) – Adds a salty kick and a beautiful finish; Pecorino Romano is another option.
• Heavy Cream (1 cup) – Gives richness and creaminess to the gratin; use half-and-half as a lighter alternative, keeping in mind the texture may differ.
For the Topping
• Crushed Pork Rinds – Adds a delightful crunch on top; for a vegetarian option, use almond flour or chopped walnuts as a substitute.
Step‑by‑Step Instructions for Creamy Spinach Gratin
Step 1: Prepare Oven and Topping
Preheat your oven to 375°F (190°C), allowing the warmth to permeate your kitchen. In a small bowl, combine crushed pork rinds with half of the shredded Gruyère and grated Parmesan. This mixture will create a crunchy topping. Set it aside while you focus on the savory base of your creamy spinach gratin.
Step 2: Sauté Aromatics
In a 10-inch cast-iron skillet, heat 2 tablespoons of olive oil over medium heat. Add the finely chopped leeks and sauté for about 3-4 minutes, or until they are softly translucent. Stir in the pressed garlic and dried thyme, cooking for another 45 seconds until fragrant, filling your kitchen with savory aromas that mark the start of a delicious gratin.
Step 3: Heat Spinach
Next, incorporate the well-drained, thawed frozen chopped spinach into the skillet. Stir the spinach for 2-3 minutes until it’s heated through and any remaining moisture evaporates. The vibrant green color of the spinach should brighten as it melds with the aromatic base, preparing for the luxurious creamy layers to follow.
Step 4: Build Creamy Base
Reduce the heat to low and add the softened mascarpone to the skillet. Pour in the heavy cream while seasoning with sea salt, black pepper, and freshly grated nutmeg. Stir continuously until the mixture is smooth and creamy, creating a rich base for your creamy spinach gratin that promises to be comforting and indulgent.
Step 5: Incorporate Cheeses
Remove the skillet from heat and fold in the remaining shredded Gruyère and grated Parmesan until fully melted and combined. The addition of these cheeses will enrich the flavor profile and create a gooey texture that surrounds your spinach. This mixture should be beautifully creamy and ready to be spread in your baking dish.
Step 6: Bake
Spread the creamy spinach mixture evenly in the skillet or transfer it to a baking dish. Sprinkle the reserved crunchy topping over the surface. Bake in the preheated oven for 20-25 minutes, or until the gratin is bubbling and the top is golden brown. This visual cue will signal that your delightful creamy spinach gratin is nearly ready to savor.
Step 7: Final Crisp & Rest
For the finishing touch, switch the oven to broil and cook the gratin on high for 1-2 minutes, watching closely to avoid burning. The top should develop a wonderful crispy layer that enhances the dish beautifully. Once done, allow your creamy spinach gratin to rest for 5 minutes before serving to set the layers and serve your masterpiece warm!

Expert Tips for Creamy Spinach Gratin
