Sheet-Pan Dinners: Browning, Not Steaming

Sheet-pan dinners promise one pan and little washing up. When they go wrong, it is almost always the same problem: the food steams in its own moisture instead of roasting. Browning needs dry heat on a dry surface. These habits make that happen.

1. Give everything space

Vegetables release water as they cook. Spread out, that water evaporates. Piled up, it pools and everything stews. Arrange food in a single layer with a little space between pieces, as in the photo above. If it does not fit, use two pans and swap their positions halfway through.

2. Use a hot oven

Most sheet-pan recipes work best between 400 and 425°F (200 to 220°C). Lower temperatures cook food through before the outside has a chance to brown. Let the oven heat fully before the pan goes in.

3. Dry and oil the food

Pat washed vegetables and meat dry with a towel. Then toss them with enough oil to coat lightly, roughly 1 tablespoon per pound (450 g) of vegetables. Oil conducts heat to the surface; too much and the food fries and turns greasy.

4. Match the timing to the ingredient

Not everything cooks at the same speed. Cut ingredients that share the pan to a similar size, or stagger them:

Times vary with size and oven, so treat them as a guide and check for doneness. Meat and fish should reach a safe internal temperature: see our safe cooking temperatures guide.

5. Leave it alone

Put potatoes and halved vegetables cut-side down, and do not stir for the first 15 to 20 minutes. Food releases from the pan on its own once a crust forms.

About the pan

A heavy, light-coloured rimmed baking sheet, about 18 by 13 inches (46 by 33 cm), browns evenly without scorching. Parchment paper helps with clean-up but check the box for its maximum temperature; many are rated to around 425°F (220°C).

Put it into practice with our lemon garlic chicken thighs or Dijon salmon with green beans.
