I start by melting butter in a medium saucepan over medium heat. Then I whisk in the flour to create a roux and slowly add milk, stirring constantly until the sauce is smooth and thickened. Finally, I add Fontal and Parmesan, letting them melt into a silky, cheesy mixture.
Next, I toss the gnocchi into the creamy sauce until each piece is coated. I season with basil, oregano, thyme, and a pinch of salt to enhance all the flavors. This step ensures every gnocchi is flavorful and perfectly creamy.
I transfer everything into a greased baking dish and sprinkle a little extra Parmesan on top for a crispy finish. Baking in a preheated oven at 375°F (190°C) for 20-25 minutes gives a golden, bubbly top that makes it irresistible.
