Frequently asked questions (FAQ's)
No, do not cover this sausage casserole while you are baking it. You want the casserole to brown on the top.
This dish is done when it reaches 160 degrees in the center of the casserole and the top is browned. Use an instant-read thermometer to check for doneness.

Top Tip
Use slightly stale or day old croissants. They soak up the custard better without turning soggy. Fresh ones can get mushy fast, but day-olds hold their flaky texture and give you that buttery, golden top with a tender inside.
Bonus tip: split them in half if they're extra puffy so every bite gets coated in that savory eggy goodness.
