Two identical dishes - how do I adjust temp and time for two 9x13 pans instead of just one? It calls for one being baked at 350 for 40-45 minutes.
Likely no adjustment is necessary if they fit in your oven with good circulation. If it is a tight fit, you might want to add a few minutes, and/or rotate them halfway through the cooking. Your best approach is to simply measure the temperature of your product around the 45 minute mark and adjust from there.
