Directions
Place the zucchini slices in a colander, sprinkle with Pink Himalayan salt, and let sit for 30-45 minutes to draw out excess water.
Preheat your oven to 400°F / 200°C.
While the zucchini rests, prepare the sauce. Melt the Brie cheese and butter in a small saucepan over medium-low heat, stirring until smooth and combined, about 2 minutes.
Pat the zucchini slices completely dry with a paper towel.
Arrange them in a slightly overlapping layer in an 8-inch baking dish and season with black pepper.
Pour the melted Brie and butter sauce evenly over the zucchini.
Sprinkle the shredded Gruyere cheese over the top.
Top with the crushed pork rinds for a crispy crust.
Bake for 25 minutes, or until the gratin is bubbling and the top is golden brown.
Serve immediately.
Don't Skip the Weeping: To avoid a watery gratin, it's crucial to salt the zucchini and let it sit for at least 30-45 minutes.
Pat the slices dry with a paper towel afterward to ensure a creamy, not soupy, sauce.
Grate Your Own Cheese: Pre-shredded cheese contains starches that add carbs and prevent smooth melting. For the best gooey, cheesy texture, buy blocks of Gruyere and Brie and prepare them yourself.
Add a Flavor Kick: For a little extra depth, add a pinch of cayenne pepper or a dash of nutmeg to the Brie and butter sauce as it melts. It beautifully cuts through the richness of the cheese.
