FAQs — Creamy Potato, Mushroom, and Brie Bake with Caramelized Onions

Q: Can I use regular bacon instead of turkey bacon?
A: Yes. Regular bacon adds more smoky flavor and fat. Cook it the same way and drain a little if it seems too greasy.

Q: Can I make this ahead and bake later?
A: Yes. Assemble the dish, cover, and refrigerate up to 24 hours before baking. Let it sit at room temperature 20 minutes before it goes in the oven.

Q: What knife or tool is best for slicing the Brie?
A: Use a sharp, thin-bladed knife or a cheese slicer to get even Brie slices. Buy it here.

Q: Can I reduce the cream to make it lighter?
A: You can reduce heavy cream and add more milk, but the bake will be less rich. Use 1 cup heavy cream and 1½ cups milk as a lighter option.
