The best oven setting for roasting depends on the food, but generally uses high heat (180°C - 230°C / 350°F - 450°F) with the 'Roast' or 'Bake' setting, often with convection for even browning and crisping, especially for meats and vegetables; smaller items or delicate foods might use lower heat (around 180°C / 350°F) for slower cooking. For large roasts, start high then lower the temperature, or use a low-and-slow method (around 120°C / 250°F) for tenderness, always monitoring with a thermometer.
Roasting is typically used for foods with a solid structure such as vegetables and meats. Roasting generally uses the bake setting at about 400ºF (204ºC) or higher to brown the surface and develop flavor.
Set Your Oven to the Right Temperature
With regards to meat, you want to use low (120°C) to moderate (190°C) heat for large roasts so they'll cook evenly and slowly (high heat would burn the outside of the roast before it's done on the inside).
Roast beef cooking time: 50 minutes to 1 hour 20, depending on how well done you like it. Roast beef temperature: Heat the oven to 240C/220C fan/gas 9 for the first 20 minutes of cooking, then lower it to 190C/170C fan/gas 5 for the remainder.
Convection Bake is good for large quantities of food and provides the best performance for cookies, biscuits, brownies, etc. Whereas convection roast is good for larger, tender cuts of meat, when cooking uncovered such as meat or poultry. I hope that answered your question.
Certain baked goods, however, are best cooked using conventional oven settings. Avoid convection baking foods like cakes, quick breads, custards, and other delicate desserts and pastries.
ROAST TO DESIRED DEGREE OF DONENESS
The main difference between baking and roasting oven settings is temperature. Large cuts of meat and firm vegetables have a roasting temperature of around 400°F and up, while the baking temperature for recipes like breads, pies and casseroles is around 350°F and lower.
Convection ovens are great for roasting foods such as meats and vegetables, as the circulating air creates a golden brown crust at ease.
Convection cooking is ideal for roasting meats and vegetables, but it can dry out delicate baked goods or lean proteins.
How to Make Tender Roast Beef: Go Low and Slow. She starts the roast at a high temperature to get browning for flavor, and then lowers the oven temp and cooks the beef "slow and low" for a couple hours.
Roasts and Brisket Internal Temp
These tough cuts have high quantities of tight connective tissue and dense fats. These tissues begin to break down at around 195 degrees F, but really soften between 200-210 degrees F.
Roasting uses the same type of all-over, dry heat as baking, but at higher temperatures between 400 and 450° F. Choose the roasting method to get thicker, tougher foods brown and crisp, and the baking method to retain moisture in thinner, more delicate foods.
Roasting at a low to medium temperature
I usually start with the oven at 80°C (176°F) and then see how it goes. If it seems like it will not be finished in time, I turn up the temperature to 100°C (212°F). I can also be found to, once in a while, to turn it all the way up to 120°C (248°F).
Many convection ovens have different settings within the convection feature. The Convection Bake setting will have a lower fan speed, which is good for longer, drier recipes, whereas the Convection Roast setting has a higher fan speed, and is perfect for crisping the outsides of meat or vegetables.
Fan ovens are versatile and suitable for various cooking methods, including baking, roasting, and grilling.
If a recipe calls for 180°C in a fan oven, you usually set the fan oven to 160°C (or sometimes 170°C, depending on the recipe/oven), as fan ovens cook hotter and faster, so you reduce the temperature by about 20°C to get the same result as a conventional oven set to 180°C. For a standard (non-fan) electric oven, 180°C is common, equivalent to about 160°C fan or Gas Mark 4.
While you're waiting, preheat your oven to the recommended temperature. You'll notice our chart selects low to moderate heat, in the range of 325 or 350 degrees, for larger roasts and higher heat, above 400 degrees, for smaller, tender roasts to produce the best results.
Roasting is similar to baking—you're using the same heating elements of your oven—but it's done at higher temperatures, beginning at 400F. A higher temperature creates more browning, crisping, and even caramelization on the outside, while keeping the inside soft and tender.
"Often consumers will inquire about adding water to the bottom of their roasting pans. We do not recommend adding water to the bottom of the pan. Cooking a turkey with steam is a moist heat-cook method and is acceptable, sure, but is not the preferred method for cooking your turkey."
Meat should always come up to room temperature before roasting it. Take it out of the fridge at least an hour before roasting. In the meantime, preheat the oven and put the meat onto a sufficiently large roasting tin. Oil and season meat to enhance flavour and prevent drying.
