Step-by-Step Instructions
- Preheat your oven to 400°F (200°C) and grease a 9x13-inch baking dish with unsalted butter.
- In a skillet, melt 4 tablespoons of unsalted butter over medium heat and whisk in 1/4 cup of all-purpose flour, cooking until golden.
- Gradually whisk in 2 cups of whole milk and 1 cup of vegetable broth, stir for 2-3 minutes until the sauce thickens.
- Remove from heat and stir in 2 minced garlic cloves, 1 teaspoon of fresh thyme, 1/2 teaspoon of sea salt, and black pepper to taste.
- Layer half of the sliced Yukon Gold potatoes and half of the sliced onion in the greased baking dish. Pour half of the sauce over the layer and sprinkle with 1 cup of cheddar cheese.
- Repeat the layering process with the remaining potatoes, onions, sauce, and add another 1/2 cup of cheddar on top.
- Cover with foil and bake for 30 minutes, then remove the foil and bake for another 35-40 minutes until tender and golden.
- Let the dish rest for 20 minutes before serving to enhance the flavors and make it easier to cut.

Notes
Potatoes should be sliced evenly for uniform cooking. Adjust the seasoning of the sauce to your liking before layering.
