Thick rounds of potato boiled until tender, pressed flat, then loaded with garlic butter and parmesan and baked until the tops go blistered and brown. Crisp edges, creamy centres, and a cheese crust that cracks under a fork.
The technique that matters is par-boiling before they go in the oven. A raw potato round of this thickness needs close to an hour of dry heat to cook through, and by then the cheese on top has burnt black. Boiling for twelve minutes first means the potato is already done, and the oven’s only job is browning.
Twenty minutes of prep, twenty-five in the oven, and they come out of the dish in one piece.
Why You Will Love This Recipe
The centres are genuinely creamy. Par-boiling cooks the potato through evenly, so there is no chalky, undercooked middle under the cheese.
The tops go properly golden. Because the potato is already tender, you can run the broiler hard at the end without worrying about the inside.
They hold their shape. Rounds pressed rather than sliced thin stay intact when you lift them out.
Four ingredients carry it. Potatoes, butter, garlic, and parmesan. Everything else is seasoning.
They work as a side or a starter. Alongside a roast, or on their own with sour cream to dip.

Choosing the Right Potatoes
Starch content decides whether these hold together or fall apart in the water.
Yukon Gold. The best choice by a clear margin. Medium starch, waxy enough to survive boiling and pressing, and buttery enough to taste good on their own.
Red potatoes. Waxy and very sturdy. They hold their shape perfectly but stay firmer in the centre and never go quite as creamy.
Russets. High starch and fluffy, which sounds appealing but means they crumble when pressed and can fall apart in the boiling water. Reduce the boil to eight minutes if this is what you have.
Fingerlings. Excellent flavour, though the rounds come out small and you will need many more of them.
New potatoes. Waxy and pleasant, but the diameter is too small to give you a proper round.
Choose potatoes of similar diameter so the rounds are uniform, and look for firm skins with no green patches or sprouting.
Why Par-Boiling and Fresh Parmesan Both Matter
A one-inch round of raw potato is dense and full of water. In a 400°F oven, heat reaches the centre slowly, and the surface dries out and hardens long before the middle is tender. That surface layer then acts as insulation, slowing things further. This is why raw potato dishes of this thickness take so long and often come out with a firm, waxy core.
Water conducts heat into food far more efficiently than air does. Twelve minutes at a simmer brings a round of this size to fully tender throughout, and it happens evenly from every side at once. Once that is done, the oven has only one job left, which is to brown the outside and melt the cheese. That takes twenty-five minutes rather than an hour, and nothing burns on top while it waits.
Pressing them after boiling adds surface area. Each flattened round has more exposed top for the garlic butter to soak into and more area for the cheese to crisp against.
The parmesan needs to be grated from a wedge for the same reason cheese always does: the anti-caking coating on pre-grated cheese prevents a smooth melt and leaves a grainy, oily crust. Parmesan is also the cheese that browns best of any, because it is low in moisture and high in protein, which is exactly what produces those dark blistered patches on top.
How to Make Cheesy Garlic Potato Rounds
Step 1: Cut the potatoes into thick rounds
Peel the potatoes and slice them into rounds about ¾ to 1 inch thick. Keep them even.
Thickness matters more than perfection. Uneven rounds cook at different rates.
Step 2: Boil in salted water
Bring a large pot of well-salted water to a boil and add the rounds. Simmer 10 to 12 minutes, until a knife slides in with slight resistance.
Do not cook them to complete softness. They still have twenty-five minutes in the oven ahead of them.
Step 3: Drain and dry
Drain carefully and spread the rounds on a towel. Let them steam dry for 5 minutes.
Dry surfaces brown. A wet round steams under the cheese instead of crisping.
Step 4: Make the garlic butter
Melt the butter and stir in the minced garlic, salt, pepper, and thyme. Let it sit while the potatoes dry so the garlic infuses.
Step 5: Arrange and press
Set the rounds in a buttered baking dish in a single layer, close together, then press each one gently with the base of a glass until it flattens and cracks slightly at the edges.
Press firmly but not hard. You want them flattened by about a third, not smashed apart.
Step 6: Brush with garlic butter
Spoon the garlic butter generously over each round, making sure the garlic pieces land on top rather than staying in the bowl.
The cracks from pressing let the butter run down inside. That is where the flavour comes from.
Step 7: Add the cream and cheese
Drizzle the heavy cream around the dish, then pile the parmesan and gruyère on top of each round.
The cream goes around the base, not over the top. It keeps the bottoms from drying while the tops brown.
Step 8: Bake
Bake at 400°F for 20 minutes, until the cheese has melted and set.
Step 9: Broil and rest
Switch to the broiler for 3 to 5 minutes, until the tops are deeply browned in patches. Rest 5 minutes, then scatter with parsley.
Watch it closely. Parmesan goes from golden to burnt in under a minute at broiler heat.
Tips for the Best Potato Rounds
Salt the boiling water heavily. It is the only chance to season the inside of the potato. The water should taste like a light broth.
Keep the rounds thick. Under ¾ inch they lose their structure when pressed and dry out in the oven.
Pack the dish tightly. Rounds set close together keep each other moist. A spread-out dish dries at the edges.
Grate the cheese coarsely. Fine shreds melt too fast and burn before the browning develops.
Use a light hand with the press. The goal is flattened with cracked edges, not broken into pieces.
Easy Variations
• Add crumbled bacon over the cheese in the last 10 minutes of baking
• Swap the gruyère for mozzarella for a stretchier, milder top
• Stir a tablespoon of Dijon into the garlic butter for a sharper edge
• Use rosemary in place of thyme for a stronger, more resinous flavour
• Add a pinch of chilli flakes to the butter for gentle heat
• Finish with a spoonful of sour cream and chives on each round
What to Serve With It
These sit naturally beside a roast chicken, a steak, or a Sunday joint, where they replace both the roast potatoes and the gratin.
As a starter, serve them with sour cream, garlic aioli, or a herbed yoghurt for dipping. A sharp green salad alongside balances the richness of the butter and cheese.
Make-Ahead and Storage
Make ahead. Par-boil and press the rounds up to a day ahead, keep them covered in the fridge, and finish with butter and cheese before baking. Add 5 minutes to the bake from cold.
Fridge. Store baked rounds in an airtight container for up to 3 days.
Freezer. Freeze par-boiled and pressed rounds, before butter and cheese, for up to 2 months. Bake from frozen and add 10 minutes.
Reheating. A 400°F oven for 10 minutes, or an air fryer at 375°F for 6 minutes. The microwave turns them soft and is best avoided.
Frequently Asked Questions
Can I skip the par-boiling?
Not with rounds this thick. Raw potato at one inch needs close to an hour, and the cheese will burn long before then.
Why did my potatoes fall apart?
Almost certainly russets, or they were boiled too long. Yukon Gold at 10 to 12 minutes holds together reliably.
Can I leave the skins on?
Yes, and it works well with thin-skinned potatoes. Scrub them thoroughly and cut slightly thicker rounds.
Can I make these in an air fryer?
Yes. After par-boiling and topping, cook at 380°F for 12 to 15 minutes in a single layer.
What if I do not have gruyère?
Sharp cheddar, fontina, or comté all work. The parmesan is the one that is not optional, since it does the browning.
How far ahead can I assemble them?
Fully assembled with cheese, up to four hours in the fridge. Beyond that the cream soaks in and the tops go soft.
