- Preheat oven to 425 F
- Drain the tomatoes. Very gently, squeeze the juice out of each tomato, keeping it as intact as possible. Lay the tomatoes on a double-layer of paper towel. Set aside.
- Chop the asparagus, carrots, and onions. Place them all in a large bowl.
- Break apart a full head of garlic but do not remove the peels from the cloves themselves. Add the garlic cloves to the bowl with the vegetables.
- Drizzle the oil over the vegetables and stir to coat. Sprinkle with herbs, pepper, and 1 teaspoon of salt. Toss gently to combine.
- Pour the vegetables onto a lined sheet pan, and spread them out as much as possible.
- Nestle the tomatoes in among the vegetables. Drizzle each tomato with a tiny bit of olive oil, and give them each a pinch of salt and a turn of black pepper.
- Place the sheet pan in the center of the oven at 425 F for 45 minutes.
- While the vegetables roast, chop the potatoes into 1” pieces (no need to peel them) and place the potatoes in a large pot.
- Cover the potatoes with cool water and add a large pinch of salt
- Put the pot over medium-high heat and allow it to come to a boil, uncovered.
- Boil gently for 12-15 minutes, or until the potatoes are soft all the way through when pierced with a fork.
- Drain the potatoes and place them back into the pot. Cover tightly until vegetables are finished roasting.
- When the vegetables are finished, remove from the oven and remove ALL of the garlic cloves.
- In a small bowl, squeeze each garlic clove so that the soft, roasted part comes out into the bowl. Discard the peels or freeze to add when making stock.
- Add 1 teaspoon of olive oil to the garlic and mash completely with a fork.
- Add the garlic mixture, chopped parsley, and 1 teaspoon of kosher or sea salt to the potatoes – use a spoon or masher to mash the potatoes to your desired consistency. Add salt/pepper/olive oil to achieve your preferred texture.
- Transfer the potatoes to a large serving dish and spoon the roasted vegetables over the top.
Optional: drizzle with balsamic vinegar
