Christmas morning should be about stockings and coffee, not standing at the stove. A Christmas morning breakfast bake solves that: you assemble it the night before, slide it into the oven when the first person wakes up, and serve a hot breakfast to everyone at once.

Here are 15 make-ahead ideas, savory and sweet, with a base method you can adapt, a night-before timeline and quantities for feeding a crowd. These are classic home-style combinations, so use the doneness and temperature checks below.

How to plan a stress-free Christmas breakfast

• Pick one savory and one sweet bake. An egg bake plus a French toast casserole covers every taste.
• Assemble the night before. Most egg bakes and bread-based casseroles improve as the bread soaks overnight.
• Plan oven time. Two 9x13 dishes usually fit side by side in a standard oven; check yours the day before.
• Add easy sides: fruit salad, yogurt, juice and coffee need no cooking.
• Take the dish out early. Let refrigerated casseroles sit on the counter while the oven heats (about 30 minutes; the USDA says perishable food shouldn't sit out more than 2 hours in total). If you use a glass dish, avoid moving it straight from fridge to a very hot oven; check the manufacturer's guidance.

The base method for any savory egg bake

Use this template for the savory ideas below.

For a 9x13-inch dish:

• 10 to 12 large eggs
• 2 cups (480 ml) milk
• 1 tsp salt and ½ tsp black pepper
• 1½ to 2 cups shredded cheese
• About 4 to 6 cups of "base" (bread cubes, frozen hash browns or biscuit pieces)
• 2 to 3 cups cooked fillings (cooked sausage or bacon, sautéed vegetables)

Method:

1. Grease the dish. Spread the base in an even layer, then add the cooked fillings and most of the cheese.
2. Whisk the eggs, milk, salt and pepper and pour over the top. Press down gently so the base soaks.
3. Sprinkle with the remaining cheese, cover and refrigerate overnight.
4. Bake uncovered at 350°F (175°C) until puffed, golden and set in the center, usually about 45 to 60 minutes from cold. Tent with foil if the top browns too fast.
5. Rest for 10 minutes before cutting.

Food safety: always cook raw meat and drain it before adding it to the dish, and keep the assembled casserole refrigerated at 40°F (4°C) or below until baking. The USDA's safe minimum internal temperature chart lists 160°F (71.1°C) for eggs and 165°F (73.9°C) for casseroles, so bake until a food thermometer in the center reads 165°F. Refrigerate leftovers within 2 hours (USDA "Danger Zone" guidance).

Savory egg bakes

1. With hash browns

Use thawed frozen shredded hash browns as the base with cooked breakfast sausage and cheddar. Pat the potatoes dry so the bake isn't watery. It's one of the most popular Christmas breakfast casseroles for good reason.

2. With biscuits

Tear refrigerated biscuit dough into pieces as the base, then add cooked sausage, cheddar and the egg mixture. The biscuits puff into soft, golden pillows. Bake until the biscuit pieces in the center are cooked through, not doughy.

3. Vegetarian spinach and feta

Sautéed spinach (squeezed dry), roasted red peppers, crumbled feta and bread cubes. Squeeze the spinach well; excess water makes the bake soggy.

4. Ham and Swiss strata

Day-old bread cubes, diced cooked ham, Swiss cheese and a little Dijon mustard whisked into the eggs. A good use for leftover holiday ham.

5. Bacon, cheddar and green onion

Crisp crumbled bacon, sharp cheddar and sliced green onions on a bread or potato base.

6. Mushroom and Gruyère

Sautéed mushrooms and shallots with Gruyère and fresh thyme on cubed sourdough. Elegant enough for a brunch.

7. Southwest egg bake

Cooked chorizo or black beans, peppers, onions, Monterey Jack and a little cumin, served with salsa and sour cream.

8. Broccoli and cheddar

Small blanched broccoli florets with cheddar on a bread base. A vegetable-forward option kids often like.

9. Christmas colors bake

Red peppers, spinach and mozzarella give red, green and white layers. Festive with almost no extra work.

10. Sausage and pepper croissant bake

Torn day-old croissants make a rich, buttery base for sausage, peppers and cheese.

Sweet breakfast bakes

11. French toast casserole

Cube a loaf of day-old brioche, challah or French bread into a greased 9x13 dish. Whisk 8 eggs, 2 cups milk, ⅓ cup sugar, 2 tsp vanilla and 1 tsp cinnamon, pour over, cover and refrigerate overnight. Top with a crumble of butter, brown sugar and flour before baking at 350°F until puffed and set in the center, usually about 45 to 55 minutes. Check that the center reaches at least 160°F, the USDA figure for egg dishes. Serve with maple syrup and powdered sugar.

12. Cinnamon roll bake

Cut refrigerated cinnamon rolls into quarters, scatter in a greased dish, pour over a mixture of eggs, milk, vanilla and cinnamon, and refrigerate overnight. Bake until set, golden and at least 160°F in the center, then drizzle with the included icing.

13. Gingerbread French toast bake

Make the French toast casserole above with ½ tsp ground ginger, a pinch of cloves and a tablespoon of molasses whisked into the custard.

14. Cranberry-orange bread bake

Add dried or fresh cranberries and orange zest to the French toast casserole. Leftover slices of our Christmas bread make a lovely base.

15. Pumpkin bread bake

Cube leftover pumpkin bread or moist banana bread and use it in place of plain bread. Reduce the sugar slightly, since the bread is already sweet. For a dessert version, try our pumpkin bread pudding.

Choosing the right bread or base

The base gives a breakfast bake its structure, so it's worth picking carefully.

• Day-old bread soaks up custard without falling apart. If your bread is fresh, cube it and leave it out for a few hours, or toast the cubes lightly in a low oven.
• Brioche and challah are rich and tender, ideal for sweet bakes.
• Sourdough and French bread are sturdier and slightly tangy, good for savory stratas.
• Frozen hash browns should be thawed and patted dry; frozen potatoes release water as they bake.
• Refrigerated biscuit or croissant dough puffs as it bakes, so leave a little room at the top of the dish.
• Gluten-free bread works in place of regular bread; it may soak up liquid differently, so check the texture before baking.

Troubleshooting

• Soggy or watery bake: vegetables weren't cooked and drained, or the hash browns weren't dried. Squeeze and drain fillings well.
• Center still wobbly: bake longer, tenting with foil if the top is browning, and check the center temperature.
• Dry or rubbery eggs: overbaked. Take it out once the center is set and at a safe temperature, then let it rest.
• Sweet bake too dense: the bread was too fresh or packed too tightly. Use day-old bread and scatter it loosely.

Night-before timeline

Feeding a crowd: quantities

A 9x13-inch breakfast bake typically gives about 8 to 12 servings, depending on how large you cut the squares and what else is on the table.

If most guests are big eaters or it's the only meal before a late Christmas dinner, plan on the larger number of dishes.

Merry Christmas morning

The best Christmas morning breakfast bake is the one you can put together on Christmas Eve and forget about until morning. Choose one savory and one sweet idea, prep the fillings in the afternoon, assemble in the evening, and let the oven do the work while everyone opens stockings.
