How far ahead can I assemble the Egg Sausage Casserole?

You can definitely put your casserole together the night before and refrigerate it until baking time. Many cooks recommend giving it at least 4–6 hours to allow the flavours to settle, and up to 24 hours works well too.

Can I substitute bread cubes with hash browns or skip them entirely?

Yes — you can replace cubed bread with thawed hash browns or even omit the starch layer for a lighter version. Just make sure whatever you use can absorb the egg mixture so the casserole holds together well.

How should I store leftovers and can I freeze this breakfast bake?

Once the casserole has cooled, store leftovers in an airtight container in the fridge for 3–4 days. For freezing, wrap individual portions in foil or freezer bags, thaw overnight in the fridge, and re-heat in a 350°F oven until warmed through — texture stays surprisingly good.
