I make this for every potluck. It is always requested by at least one person so I keep making it. Warning: I don't measure stuff...
1 bag of red potatoes (You can whatever kind. I like the red and one bag is the right amount.)
1 bag baby carrots
1 bag pearl onions
At least 2 bulbs of garlic (love garlic)
1 TBS each of Thyme, Rosemary, and Basil (I just pour some in my hand to measure)
1-2 tsp pepper
A sprinkle of sage (that one's easy to overdo)
Enough olive oil to coat veggies. I just give it a swirl over the pan.
Preheat oven to 375
Wash and cut potatoes to approximately the same size as baby carrots. Peel onions and garlic (if any cloves are real big I slice them in half, otherwise, whole cloves). Put all the veggies in a roasting pan and drizzle olive oil over them. Sprinkle herbs on and toss to coat. Cover with aluminum foil and roast for at least 2 hrs (It always seems to take a different amount of time. Cook until potatoes are soft.)
Clear as mud? It's really not possible to mess it up.
