Alright, breakfast lover, this one’s just for you. If mornings feel rushed and cooking feels like a chore to you, let me put you onto something that might just change your game:

Overnight Breakfast Casserole. You prep it the night before, wake up, bake it, and boom—a warm, filling breakfast ready to go.

How to Make Overnight Breakfast Casserole: Step-by-Step Instructions

Ingredients

8 large eggs
2 cups whole milk
1/2 cup heavy cream
1 tsp salt
1/2 tsp black pepper
1/2 tsp garlic powder
1/2 tsp onion powder
6 cups bread, cubed (day-old or slightly stale is best)
1 lb breakfast sausage, cooked and crumbled
1 cup shredded cheddar cheese
1/2 cup shredded mozzarella cheese
1/4 cup chopped green onions
Cooking spray or butter for greasing

Step-by-Step Instructions

Step 1: Grease a 9×13-inch baking dish. You don’t want to be scraping crusty eggs off in the morning.

Step 2: Spread the cubed bread evenly into the dish. Don’t pack it down, just let it hang out naturally.

Step 3: Sprinkle the cooked sausage all over the bread. Crumbles work best, so every bite gets some.

Step 4: Add the cheddar and mozzarella cheeses. More cheese? Yes, please.

Step 5: In a big mixing bowl, whisk the eggs, milk, cream, salt, pepper, garlic powder, and onion powder until they’re all smooth and creamy-looking.

Step 6: Slowly pour the egg mixture over everything in the baking dish. Go easy to make sure the liquid soaks through.

Step 7: Top it all off with green onions.

Step 8: Cover the dish tightly with foil or plastic wrap. Put it in the fridge overnight.

Step 9 (Morning time!): Preheat your oven to 350°F (175°C). Remove the casserole from the fridge while the oven preheats.

Step 10: Bake uncovered for 50-60 minutes until the top is golden and the center is set. Stick a knife in, if it comes out clean, you’re golden.

Step 11: Let it cool for 5-10 minutes before slicing. Then serve it up hot!

Common Mistakes to Avoid

⑴ Using fresh bread: It gets too soggy. Go for slightly stale bread so it holds up.

⑵ Not greasing the pan: That casserole isn’t coming out clean if you skip this step.

⑶ Overbaking: Nobody likes dry eggs. Keep an eye on it after 50 minutes.

⑷ Not letting it sit before cutting: You’ll end up with a sloppy mess. Give it a few minutes to set.

Recipe Best Tips

Use a mix of cheeses for flavor depth.
If sausage isn’t your thing, swap in cooked bacon or a veggie alternative.
Want more veggies? Add chopped bell peppers or spinach.
Use a serrated knife for cleaner slices.

Serving Suggestions

① Serve with a side of fresh fruit or a small green salad.

② A dollop of sour cream or salsa on top adds a great taste.

③ Pair it with coffee or orange juice for the full breakfast spread.

Storage and Freezing

Fridge: Store leftovers in an airtight container for up to 4 days.
Freezer: Wrap individual portions tightly in foil or plastic wrap, then freeze up to 2 months.
Reheat: Microwave individual slices or reheat in the oven at 300°F until warmed through.

Frequently Asked Questions (FAQs)

Q1: Can I make this dairy-free?

Yes, use plant-based milk and dairy-free cheese. Make sure it’s unsweetened and unflavored.

Q2: What kind of bread works best?
Day-old French bread, sourdough, or even whole wheat. Just don’t use super soft sandwich bread.

Q3: Can I prep this more than one night ahead?
Absolutely! Two nights ahead is fine. Just make sure it’s sealed tight in the fridge.

Q4: Can I use egg whites only?
You can, but the texture might be a bit drier. I recommend mixing whole eggs with some whites if you’re trying to lighten it up.

Q5: How do I know it’s done baking?
Check the center with a knife. If it comes out clean and the top is golden, you’re good.

Q6: Can I skip the meat?
Of course. Just load it up with veggies and maybe an extra sprinkle of cheese.

Q7: Can kids help make this?
Definitely! Let them tear up the bread, sprinkle cheese, or whisk the eggs.
