Wash the potatoes, scrubbing with a brush if you have one. Quarter the potatoes or cut into sixths depending on their size and place them in a large baking dish.
15 medium red potatoes
Add the chopped onion and garlic.
1 large sweet onion, 3 cloves garlic
Drizzle with the oil and then toss everything with your hands. Get in there and massage; you want to coat the potatoes in a little oil and spread out the garlic and onion really well.
2 tablespoon avocado oil
Sprinkle on the salt and pepper.
1 teaspoon kosher salt, Pinch of black pepper
Roast for 40 minutes tossing and turning at least once halfway through.
