Method
Prepare the pan
- Heat the oven to 375°F.
- Grease a 9x13-inch baking dish with the softened butter.
Make the sauce
- Melt the butter in a medium saucepan over medium heat.
- Add the garlic and cook for 30 seconds.
- Whisk in the flour and cook for 1 minute, whisking constantly.
- Gradually whisk in the milk and cream.
- Simmer for 2 to 3 minutes, whisking, until the sauce is lightly thickened.
Assemble and bake
- Toss the turnips with the salt and pepper.
- Arrange the turnips in overlapping layers in the baking dish.
- Pour the sauce evenly over the turnips.
- Cover the dish tightly with foil and bake for 45 minutes.
- Remove the foil.
- Sprinkle the Gruyère evenly over the top.
- Bake uncovered for 20 to 30 minutes, until a knife slides easily into the turnips and the cheese is golden.
- Let the dish rest for 15 minutes before serving.
Notes
For the most even texture, slice the turnips uniformly. Refrigerate leftovers for 3 to 4 days; freezing is not recommended because the creamy sauce may separate. For a gluten-free variation, use a 1:1 gluten-free flour blend in place of the all-purpose flour.
