Preheat oven to 400F/200C. Line a baking sheet with parchment paper and put it aside.
Wash the baby potatoes well. If they are small enough, leave them whole. Halve the large ones. Put them on the baking sheet in a single layer. Add in the garlic cloves and fresh rosemary.
Drizzle olive oil and sprinkle salt and pepper over them.
Roast for 30 minutes or until golden.
NOTES
If the potatoes are larger than an orange, it's better to halve them.
We never turn them during roasting, but you might need it depending on your oven.
You can use large potatoes too, but slice them in wedges or cut in 1-2 inch cubes.
Store the leftovers in an airtight container in the fridge for 1-2 days.
To reheat, put them in a baking pan with a drizzle of olive oil and heat in a preheated oven for 5 minutes. Alternatively, you can simply heat them in a frying pan.
