How long to cook breakfast casserole at 350 degrees when the recipe states for 15 minutes 425 degrees?

You can't directly convert cooking times based on temperature alone. Here's why and how to adjust:

Factors that Affect Cooking Time:

* Casserole Density: A dense casserole with lots of cheese and meat will take longer than a lighter one.

* Pan Size and Material: A larger or shallower pan will require longer cooking time. Darker pans tend to heat up faster.

* Oven Variations: Ovens can vary in temperature accuracy.

Estimating Time:

While it's hard to give a precise time, here's a general guideline:

* Increase the time: Since you're cooking at a lower temperature (350°F instead of 425°F), you'll likely need to increase the cooking time.

* Start with a 50% increase: A good starting point is to increase the cooking time by 50% (so 15 minutes x 1.5 = 22.5 minutes).

* Check for Doneness: Use a thermometer to check the internal temperature. A breakfast casserole is done when the internal temperature reaches 165°F.

* Adjust as Needed: If the casserole is still soft or undercooked after the initial time, add 5-10 minutes and check again.

Important Tips:

* Don't Overcook: Overcooked casserole will become dry and crumbly.

* Use a thermometer: This is the most accurate way to determine doneness.

* Start checking early: It's always better to check for doneness a little early than to overcook.

Example:

Instead of cooking your breakfast casserole for 15 minutes at 425°F, you could start with 22.5 minutes at 350°F, check for doneness, and adjust accordingly.
