Can I make cheesy smashed potatoes ahead of time?
Yes. Boil and smash the potatoes, layer with cheese, cover, and refrigerate up to 24 hours. Bake from cold, adding 5–10 minutes to the baking time.
What type of potatoes work best for this recipe?
Mini potatoes or baby potatoes are ideal because they're small and cook evenly. Red or gold varieties have thin skins and creamy texture.
Can I substitute the mozzarella and Parmesan?
Yes. Use cheddar, Gruyère, or fontina for depth, or swap mozzarella with white cheddar. Keep at least one sharp cheese for flavor.
How do I know when they're done baking?
Bake until the cheese is melted and bubbly with golden-brown edges, typically 20–25 minutes at 400°F. The top should be lightly browned.
Can I use fresh herbs other than chives?
Yes. Parsley, dill, or thyme work well. Add fresh herbs after baking to preserve their color and flavor.
