Mastering the Large Batch Roast
When you have a kitchen full of guests or a week's worth of meals to prepare, the oven is your most efficient tool. Success here relies on geometry—how you arrange your trays—and patience, ensuring you don't crowd the pan.
Space is your primary ingredient.
If you crowd your baking sheets, moisture gets trapped and the food turns mushy. Use enough pans that every piece of food has its own breathing room.
- 2-3 heavy-gauge rimmed baking sheets
- Parchment paper
- Chef's knife
- Large mixing bowl
What goes in.
- 4 lbroot vegetables (carrots, parsnips, or potatoes), cut into 1-inch chunks
- 3 lbboneless chicken thighs, trimmed
- 1/2 cupneutral oil, such as grapeseed or avocado
- 2 tbspkosher salt
- 1 tbspdried herbs (thyme or rosemary)
Single-layer spacing
Ensure no two pieces of food are touching. Air must circulate around every side of the ingredient to achieve a crisp texture rather than a steamed one.
The method.
Preheat the oven
Set your oven to 425°F. Place racks in the upper and lower thirds of the oven to ensure even heat distribution.
Dry the ingredients
Pat your chicken and vegetables dry with towels. Excess surface moisture creates steam, which is the enemy of a deep sear.
Season thoroughly
Toss vegetables and chicken separately with oil, salt, and herbs in a large bowl. Use enough oil to lightly coat every surface.
Arrange the trays
Distribute items onto rimmed sheets. Do not overlap. If you run out of space, use another tray rather than piling items high.
Roast and rotate
Place in the oven. Halfway through the cooking time, swap the positions of the top and bottom trays and rotate them 180 degrees to account for uneven hot spots.
Verify doneness
The vegetables should be tender when pierced with a paring knife and the chicken should reach an internal temperature of 165°F. The edges should be golden-brown.
Other turns to take.
Hard Winter Squash
Add cubes of butternut or acorn squash; they roast in the same time as carrots and provide a contrasting sweetness.
Alliums
Toss in whole peeled shallots or thick wedges of red onion during the last 20 minutes of roasting.
When it doesn't go to plan.
If your oven has a convection setting, turn it on and lower the temperature by 25°F for more even browning.
Do not wash your vegetables right before roasting; ensure they are completely dry to prevent steaming.
Use light-colored aluminum pans if possible; dark non-stick pans often cause the bottoms of the food to burn before the insides are fully cooked.
The ones that keep coming up.
Can I roast the meat and vegetables on the same tray?
It is better to keep them separate. Meat releases fat and juices that will cause vegetables to boil rather than roast if mixed together.
