1 cup heavy cream – This adds richness and creates the luxurious texture of the gratin; you can substitute with half-and-half for a lighter version.

1 cup Gruyère cheese, grated – Known for its nutty flavor that melts beautifully, Gruyère is a perfect choice.

½ cup Parmesan cheese, grated – This adds a salty kick with its strong flavor; feel free to grate your own for optimal freshness.

How to Make Creamy Leek and Fennel Gratin

Follow these simple steps to prepare this delicious Creamy Leek and Fennel Gratin:

Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C) and grease a medium-sized baking dish with a little butter. The greased dish will help to achieve that golden, bubbly crust we all love.

Step 2: Sauté the Veggies
In a skillet over medium heat, melt the butter. Add the sliced leeks and chopped fennel to the pan. Sauté until they are softened and fragrant, which should take about 5 minutes. Stir occasionally to avoid any browning.

Step 3: Prepare the Creamy Mixture
In a separate bowl, whisk together the heavy cream, a pinch of salt, pepper, and half of the grated Gruyère cheese. This creamy blend is going to make your gratin incredibly luscious.

Step 4: Combine and Transfer
Pour the creamy mixture over the sautéed leeks and fennel, tossing gently to blend everything. Once combined, transfer the mixture into the prepared baking dish.

Step 5: Top with Cheese
Sprinkle the remaining Gruyère cheese and the Parmesan evenly over the top of your mixture. This cheesy layer will form a beautiful golden crust while baking.

Step 6: Bake It to Perfection
Bake your gratin in the preheated oven for about 30-35 minutes or until it is golden brown and bubbling. Let it cool slightly before serving to avoid burns and to mesh those delicious flavors fully.

Enjoy your Creamy Leek and Fennel Gratin as a cozy meal on its own or as a decadent side dish that will elevate any weekday dinner or festive gathering. Don’t forget to serve it with warm, crusty bread to mop up every bit of that cheesy goodness!
