The short answer
Use a sheet pan for almost everything. A half sheet has a one inch rim, which lets hot dry air reach the sides of whatever you are roasting, so vegetables and chicken pieces brown all over instead of steaming. A roasting pan has two to three inch walls, which shade the food and trap moisture - and which are exactly what you want for a turkey, a large joint or anything where you are collecting drippings for gravy.
Wall height is the whole difference

Rows three and six are the two that decide it. If browning is the goal, low walls. If drippings are the goal, high walls.
The mechanism is simple. Food releases water as it heats. On a sheet pan that water evaporates and leaves, so the surface dries and browns. Inside a deep pan the water has nowhere to go, so the air immediately around the food stays humid and the surface stays wet - and a wet surface cannot brown.
What the sheet pan wins
Roast vegetables. Not close. Deep walls are why oven vegetables come out soft and pale rather than caramelized.
Chicken pieces, sausages, anything in portions. All-over browning.
Sheet pan dinners. An entire meal on one surface with one thing to wash.
Spatchcocked poultry. Flattened birds roast faster and brown better, and a sheet pan with a rack is the standard method.
Anything you want crisp. Bacon, potatoes, tofu, croutons.
Cost and storage. It is the cheapest useful thing in a kitchen and it stacks flat.
A turkey, a large chicken, a rib roast, a leg of lamb. These render a great deal of fat, they are too heavy for a thin sheet pan to carry safely, and they need a rack that sits above the drippings.
Gravy
This is the real argument. Drippings pooled in a deep pan are protected from direct heat and stay liquid; the same drippings spread thin across a sheet pan scorch. A roasting pan that can go on a stovetop lets you deglaze and make gravy in the same vessel, which is the traditional method and still the best one.
Braising something large
Covered with foil, a roasting pan braises a joint too big for any Dutch oven. That is a once-or-twice-a-year job for most households, which is exactly the frequency that makes buying one hard to justify.
Be honest about frequency before you buy. A roasting pan is used two or three times a year in most kitchens, costs several times a sheet pan, and fits in no cupboard. It is the clearest example of a piece bought for an occasion and stored for a year - best roasting pans covers what to look for if you decide you need one.
The middle ground nobody mentions
Between a 1 inch rim and a 3 inch wall there is a 2 inch baking dish, and it covers a surprising amount of ground.
A 9 by 13 in glass or ceramic dish holds liquid, will not scorch drippings, and goes to the table. It cannot go on a stovetop - best baking dishes and casseroles.
A 6 qt Dutch oven roasts a whole chicken, collects drippings, and reduces them on the stovetop afterward. For anything that fits, it beats a roasting pan.
A sheet pan plus a rack gives you airflow underneath and a surface for drippings, which is most of a roasting pan's function for smaller birds - best cooling racks.
A large cast iron skillet roasts a chicken beautifully and deglazes on the stovetop - best cast iron skillets.
The rack, which matters more than the pan
A rack lifts food out of its own rendered fat so hot air circulates underneath. Without one, the underside of a roast sits in liquid and steams no matter which pan you chose.
On a sheet pan, a flat wire rack turns it into most of a roasting setup for a fraction of the cost.
In a roasting pan, a V-rack cradles a large bird and keeps it stable.
Check it is oven safe. Many cooling racks are chrome-plated and not rated for oven heat - the distinction is in best cooling racks.
A bed of thick-cut vegetables works as an improvised rack and makes gravy while it does it.
These are the products this page's reasoning actually points at. Same rules as everywhere else on the site: published specs, a stated trade-off, and a live price only where one exists.

Nordic Ware Naturals Half Sheet, 18 x 13 in
A 1 in rim and uncoated aluminum, which is the correct combination for browning almost anything.
Best for: Roasting vegetables, sheet-pan dinners, cookies - the pan you use most weeks
Published specifications for the Nordic Ware Naturals Half Sheet, 18 x 13 in
Exterior dimensions
17.9 x 12.9 x 1 in
Material
Aluminum
Rim
Encapsulated steel rim
Gauge
Not published by Nordic Ware
Warranty
Lifetime
Dishwasher
Hand wash recommended. Automatic dishwasher use is not advised
Made in
America of domestic and imported materials
Good
Aluminum conducts at 237 W/m-K, which is why it browns evenly and a steel pan does not
The encapsulated steel rim is the reason it does not warp in a hot oven
Lifetime warranty on a pan this cheap
Not good
Nordic Ware does not publish a gauge figure, so thickness cannot be compared like for like
Bare aluminum stains and reacts with acid
Not dishwasher safe by the maker's own advice
The trade-off. Bare aluminum discolors and reacts with acid. It will look used within a month and Nordic Ware advises against the dishwasher.
Skip this if. You want a pan that stays looking new, or you will not hand wash. Buy an aluminized-steel coated pan instead and accept the coating as a wear item.
Published specifications for the Lodge Enameled Cast Iron Dutch Oven, 6 qt
Material
Cast iron with porcelain enamel, inside and out
Capacity
6 qt
Induction
Yes - the iron under the enamel is ferrous
Seasoning
None required - enamel is not a seasoning surface
Acid
Safe for tomato and wine, unlike bare iron
Oven maximum
Set by the knob material - check the specific SKU; Lodge publishes a lower ceiling than for bare iron
Good
Non-reactive, so it handles the acidic cooking bare iron cannot
No seasoning to maintain
Considerably cheaper than the French enameled pots it copies
Not good
Chipped enamel is not repairable, unlike bare iron's seasoning
Oven ceiling is lower than bare cast iron because of the knob
Heavy, and the enamel makes it heavier than bare iron of the same capacity
The trade-off. The enamel is a glass layer. Chip it and the pot is not restorable the way bare iron is, and Lodge's enamel chips more readily than the premium brands'.
Skip this if. You already own a large stainless stockpot and rarely braise. This duplicates it for most weeknight cooking.
For almost everything, yes, and it will brown better - a 1 inch rim lets hot dry air reach the sides of the food. Add an oven-safe rack and it covers most of a roasting pan's function. The exceptions are large turkeys and joints, and gravy from pooled drippings.
›Why don't my vegetables brown in a roasting pan?
The walls. Food releases water as it heats, and in a deep pan that moisture has nowhere to go, so the air around the food stays humid and the surface stays wet. A wet surface cannot brown. Use a sheet pan instead.
›Do I need a roasting pan?
Only if you roast large birds or joints, or want drippings collected for gravy. Most kitchens use one two or three times a year, and it costs several times a sheet pan and fits in no cupboard. A sheet pan plus a rack covers smaller roasts.
›What size roasting pan for a turkey?
Measure your oven first, then the bird. The common failure is buying a pan that will not fit with the door closed, or that leaves no gap for air to circulate around it. A V-rack matters as much as the pan, because it cradles the bird above the drippings.
›Is a Dutch oven a good roasting pan?
For anything that fits, it is better - it browns on the stovetop, collects drippings, and reduces them into gravy in the same vessel. The limit is size: a whole turkey does not fit in a 6 quart pot.
