When baking, if your oven can't reach the temperature stated in the recipe, do you then just adjust for time? - feddit.nl

I have an oven that’s rated to reach 200 degrees C (around 400-ish in F) (I can’t put in higher temperatures on the device), but some recipes tell you to bake at higher temps than that. Does that mean that I can’t bake that item in my oven, or can I just adjust for time? Let’s say the recipe says to bake at 225 degrees C for 25 minutes, I then bake it for 35 minutes at 200?

When you lower the temperature, things take longer to cook through and brown less quickly. The usual rule of thumb is: for every 10°C (about 20°F) lower, increase baking time by roughly 5–10%. So if a recipe says: 225°C for 25 minutes, and you can only do 200°C, that’s 25°C lower, about 10-15% more baking time. So you’d bake it for around 28-30 minutes, not 35. (35 minutes would likely over-bake it unless it’s something dense). bake 27–30 minutes, and start checking for doneness around 27 minutes. Some recipes tolerate the adjustment better than others.
