Preheat the Oven: Start by preheating your oven to 375°F (190°C).
Make the Cream Mixture: In a saucepan, melt the butter over medium heat. Add the minced garlic and let it cook for a minute or two until fragrant. Pour in the heavy cream and season with salt and pepper. Heat for a couple of minutes until mixed.
Layer the Sweet Potatoes: Grease a baking dish and layer the sliced sweet potatoes evenly. Ensure each layer is seasoned with salt, pepper, and a sprinkle of thyme. Don’t skimp on layering the different cheeses as you go!
Add the Cream: Pour the cream mixture over each layer of the sweet potatoes, making sure they are well-coated. Aim for about 3-4 layers.
Top It Off: After the layers are complete, generously sprinkle the remaining cheese mixture over the top.
Bake: Cover the baking dish with aluminum foil and bake for about 45 minutes. Once the sweet potatoes are tender, remove the foil and bake for an additional 15-20 minutes, until the top is golden brown and bubbling.
Serve: Allow it to cool slightly before serving. Enjoy the creamy, cheesy goodness!
