Instructions
Heat oven to 350 degrees F. Melt the butter in a large dutch oven over medium heat. Add onion and sauté until it turns soft and begins to brown, about 4 minutes. Add garlic and sauté until fragrant, about 30 seconds.
Add cream, milk, thyme, bay leaves, salt, pepper, and potatoes and bring to simmer. If you like a crusty top, use less cream and milk. The full amounts will give you a nice creamy result.Cover and lower the heat to keep the simmer and cook until potatoes are almost tender (you should be able to poke with a fork) which should take about 15 minutes.
Remove and discard thyme sprigs and bay leaves. Transfer potato mixture to 3-quart oven dish and sprinkle with cheese.
Bake until cream has thickened and is bubbling around sides and top is golden brown, about 20 minutes. Cool for 5 minutes before serving.
Notes
For the fastest and most consistent results, use a mandolin or your food processor to slice the potatoes.
