Instructions

Prepare the potatoes

Slice the Yukon Gold potatoes 1/8‑inch thick using a mandoline or sharp knife. Rinse briefly under cold water, pat dry, and set aside on a clean kitchen towel.

Pro Tip: Even slices cook uniformly and prevent a watery casserole.

Make the Parmesan cream

In a saucepan melt butter over medium heat. Add minced garlic, sauté 30 seconds, then stir in heavy cream. Simmer gently for 3‑4 minutes, whisk in grated Parmesan until smooth. Season with salt, pepper, and thyme.

Pro Tip: Keep the heat low; high heat can cause the cheese to grain.

Layer the casserole

Grease a 9‑x‑13‑inch baking dish. Arrange half the potato slices in an even layer, pour half the cream sauce over them, then repeat with remaining potatoes and sauce. Sprinkle panko breadcrumbs and dot with a few extra butter pieces.

Pro Tip: Overlap slices slightly to avoid gaps.

Bake to golden perfection

Cover the dish with foil and bake in a pre‑heated 375°F (190°C) oven for 30 minutes. Remove foil and continue baking 15‑20 minutes, until the top is deep golden and potatoes are fork‑tender.

Pro Tip: If the top browns too quickly, loosely tent foil.

Rest and serve

Allow the bake to rest 10 minutes before cutting. This lets the sauce set, making slices neat and easier to plate. Garnish with extra thyme or a sprinkle of Parmesan if desired.

Expert Tips

Tip #1: Use a mandoline

Uniform slices cook evenly and reduce baking time, giving a smoother texture.

Tip #2: Toast the breadcrumbs

Lightly toast panko with butter before sprinkling for extra crunch and a nutty aroma.

Tip #3: Add a pinch of nutmeg

A tiny pinch brightens the cream without overwhelming the Parmesan.

Tip #4: Cool before refrigerating

Let leftovers reach room temperature; this prevents condensation that can make the crust soggy.

Storage & Variations

Cool the bake completely, then store in an airtight container in the fridge for up to 3 days; reheat covered at 350°F until hot. For a low‑fat version, replace half the cream with low‑fat milk and reduce butter. Add caramelized onions or cooked bacon for extra flavor depth.

Frequently Asked Questions

Yes, russets work, but they are higher in starch and may become fluffier. Yukon Golds give a creamier texture and hold the sauce better.

Pat the sliced potatoes dry, use a thick cream sauce, and bake covered for the first half. This traps steam and lets the sauce thicken before the top browns.

Yes. Freeze after cooling, wrapped tightly. Thaw overnight in the fridge, then bake uncovered at 375°F for 25‑30 minutes, adding extra breadcrumbs if needed.

Gruyère, aged cheddar, or Pecorino Romano work well. Adjust salt accordingly, as some cheeses are saltier than Parmesan.
