The Complete Shopping Rundown

You gotta start with the basics. Full fat cream is your best friend here, about 1 ½ cups to give that silky sauce. Two garlic cloves minced fresh, not powder, bring that subtle punch upfront.

ButterE2s the richness booster. Grab about 2 tablespoons melted so it drapes those potato slices just right. Talking potatoes, pick a starchy type like Russet or Maris Piper if you can get E22em. About 1.25 kilos or 2.5 pounds should fill your cooker nicely.

DonE2t forget salt and pepper for seasoningE2just a teaspoon and a pinch of pepper. Next up, cheese talk: Gruyere is the classic, but you can swap with cheddar, Colby, Havarti or your fave for that nice melt and golden top. YouE2ll wanna grate yourself, about 2 and a half cups.

And hey, if you want, fresh thyme leaves, two teaspoons, really brighten things up but no stress if you skip.

The Exact Process From Start to Finish

First, mix cream, garlic, salt, pepper and melted butter in a jug until itE2s all cozy together.
Peel those potatoes, then slice thin, about 3mm or ⅛ inch thickness. Try keep E2em even so they cook at same pace.
Layer one third of the potatoes on the cooker-safe dish or insert, then pour one third of the cream mix over, followed by one third of the cheese and sprinkle some thyme if you like.
Repeat those layers two more times, finishing with cheese on top to get that golden crust later.
Seal that pressure cooker lid nice and tight with your sealing ring in place. Cook on high pressure about 10-12 minutes until you see the steam cues steady.
Let it natural release for 10 minutes before opening. That sets the sauce without any scary splatters. Enjoy right after or wait ten minutes for it to set really well.

Valve Hacks You Need to Know

Always check your sealing ringE2s snug before locking the lid. It keeps the pressure steady which you donE2t wanna lose mid-cook.
If valve hisses too loud or steam escapes early, your ring might be off or thereE2s liquid insufficiency in pot.
For faster natural release, carefully nudge the valve just a smidge but donE2t fully release or youE2ll lose the tender pull moment.
Once cooking ends, tilt the lid slightly away from you when opening to dodge steam burn and catch those steam cues right.

Keeping Leftovers Fresh and Ready

If you got leftovers, pop them in an airtight container with a snug lid. Keeps good in fridge for about 3-4 days, just heat gently and add a splash of cream if it looks dry.

For longer stashing, freeze portions wrapped tight in foil and a plastic bag. When thawed, reheat slow on low heat so it warms through without drying or burning.

Reheating in a microwave? Cover it, add a tiny splash of cream or broth and heat in short bursts, stirring in between to keep that creamy texture alive.
