Yield
Serves 4 generous portions
Difficulty Level
Medium – perfect for intermediate home cooks looking to impress with minimal fuss
Ingredients
- 3 large fennel bulbs, trimmed and thinly sliced
- 3 tablespoons unsalted butter
- 1 small onion, finely chopped
- 2 garlic cloves, minced
- 2 tablespoons all-purpose flour
- 1 ½ cups whole milk, warmed
- 1 cup grated Parmesan cheese, divided
- ½ teaspoon freshly grated nutmeg
- Salt and freshly ground black pepper, to taste
- 2 tablespoons olive oil
- Fresh thyme sprigs for garnish (optional)
Instructions
- Prepare the fennel: Preheat your oven to 375°F (190°C). Slice the fennel bulbs thinly,about 1/8 inch thick,to ensure even cooking. Toss them gently in olive oil, salt, and pepper.
- Sauté aromatics: In a large skillet,melt the butter over medium heat. Add the chopped onion and sauté until translucent and fragrant, about 4 minutes. Stir in the minced garlic and cook for another minute, taking care not to burn it.
- Create the béchamel base: Sprinkle the flour over the butter, onion, and garlic mixture, stirring constantly to form a smooth roux. Cook for 2 minutes until slightly golden.
- Incorporate milk: Gradually whisk in the warm milk, ensuring no lumps form. Continue cooking on low heat,stirring often until thickened to a creamy consistency,about 5-7 minutes.
- Season the sauce: Stir in half of the grated Parmesan, nutmeg, salt, and pepper to taste. Remove from heat.
- Assemble the gratin: In a buttered baking dish, layer half of the sliced fennel evenly. Spoon half the béchamel sauce over the fennel. Repeat with the remaining fennel and béchamel.
- Craft the Parmesan crust: Evenly sprinkle the remaining Parmesan over the top layer. For extra golden crispiness, drizzle a bit of olive oil on the cheese.
- bake to perfection: Place the dish in the oven and bake uncovered for 30-35 minutes or until the top is bubbling and a deep golden crust has formed.If needed, broil the last 2 minutes for extra crunch-watch closely.
- Rest and serve: Allow the gratin to rest for 5 minutes before serving. This helps the layers set, making it easier to portion.
Tips for Success
- Uniform slicing: Use a mandoline slicer for perfectly thin, even fennel slices that cook uniformly and layer beautifully.
- Milk temperature: Warm the milk before adding to the roux to prevent clumping and ensure a smooth béchamel.
- Cheese choice: For an even richer crust, mix Parmesan with a touch of aged Pecorino Romano.
- Make-ahead: Prepare up to the baking stage and refrigerate overnight. Bring to room temperature before baking.
- Flavor layering: Add a pinch of red chili flakes to the béchamel if you want a subtle heat that complements the fennel’s sweetness.
