The best side dishes do not just fill space on the plate — they earn their spot. This scalloped potatoes au gratin is exactly that kind of recipe: simple enough to make on a busy weeknight, flavorful enough to hold its own next to any main course, and satisfying in a way that makes you reach for seconds.

Add the garlic after the other aromatics have softened — it burns faster than onions and can turn bitter if it hits high heat for too long.

This pairs well with almost any protein, from a simple roasted chicken to grilled steak or baked salmon. Make extra — it reheats well and having a ready-made side dish in the fridge makes weeknight cooking significantly easier.
