Recipe Guide
- → What type of potatoes work best?
Russet or Yukon Gold potatoes are ideal for layering due to their texture and tenderness when baked.
- → Can I substitute cheeses?
Gruyère can be swapped with Monterey Jack or mozzarella for a milder flavor while maintaining creaminess.
- → How do I ensure a creamy sauce?
Whisking flour into melted butter before slowly adding milk and cream helps create a smooth, thickened cheese sauce.
- → Is it possible to make this dish gluten-free?
Yes, substitute the all-purpose flour with a gluten-free blend to keep the sauce thick without gluten.
- → What herbs work well as garnish?
Chopped fresh chives or parsley add a bright, fresh flavor that complements the rich cheese sauce.
- → Can extra flavor be added?
Adding a pinch of cayenne or layering cooked bacon between potatoes offers a smoky, spicy kick.
