Add 50 grams melted butter, all the herbs and seasoning to the potatoes in a bowl. Toss well to coat all potatoes evenly.
Once instant pot is hot, add remaining (50 grams) butter and saute garlic in butter. Add potatoes in a single layer, do it in batch if you are cooking large batch of potatoes.
Note - I had some liquid left over after cooking. Most of it was all fat (butter) and not water. Ensure you use minimal liquid so potatoes don't loose their crispness.
