It is an ideal make-ahead dish, especially during the holidays. Prepare it the night before, and pop it in the oven the next morning for a special quick, and delicious breakfast that feeds a crowd.

What is a Strata?

Strata is a savory breakfast or brunch casserole prepared the night before and baked the following day. The basic ingredients are bread (lots of it), a custard made with eggs and milk, or eggs and cream and cheese. Meats like bacon, ham, salami, or other cold cuts and vegetables are also part of the dish.

It is an American layered egg casserole dish, very easy to make, and highly suitable for a hearty breakfast or brunch.

This egg dish is perfect for feeding a house full of guests and if you want to prepare something simple and delicious that doesn’t require a lot of time in the kitchen.

You can put the strata together before you go to bed. The next morning you just have to remove it from the fridge and bake it, which is a very unstressful way of having people over. Just like my Cheesy Ham Hash Brown Egg Casserole, this dish is easy and hearty with minimum work involved.

Strata is usually made with stale bread that is layered together with anything you have in the fridge. This is the beauty of it. You can make it with whatever you want.

The liquid base is usually milk and eggs, but I saw recipes that use sour cream and eggs instead. I personally like the strata with sour cream instead of milk.

However, if you make it with sour cream, the texture will be a little bit different, just more “egg-ish” than the one made with milk.

This dish is perfect for Christmas, Easter, any brunch that involves guests, or anytime you have people out of town visiting your house.

To make this beautiful overnight breakfast casserole, you will need:

Baking dish– for 4-6 people, you might need an 8x8x2 inches baking dish. For more than 6-8 people, you might need a 13×9 inches dish. 

Bread– Any bread will do. I like a French baguette, sourdough, French loaf, and artisan bread, but even gluten-free would work.

I like to cut the bread into chunks and leave it covered in a bowl on the kitchen counter for the day. This is how I ensure the bread is dry and ready to absorb the milk(or the sour cream) and the eggs. 

If you don’t have stale bread, then use a fresh one, but cut the bread into chunks, or just break it into pieces, place it on a baking pan, then in the oven at 350F for 5-7 minutes until the chunks are crisp on the outside but not completely dry.

When cool, measure the bread and make sure it fits in the baking dish you want to use. To serve 4-6 people, you will need about 4-5 cups of cubed bread.

Liquid base– As I said before, the traditional strata is made with milk and eggs, but the sour cream and eggs combination is perfectly acceptable. I like the sour cream. I also use it when I make quiche

Note on using the sour cream instead of milk: A strata is baked for about 40-45 minutes if made with milk. If you use sour cream with eggs instead, reduce the amount of baking to only 30-35 minutes, as there is not a lot of liquid in the pan to evaporate. 

You can flavor the liquid base the way you want it. A good start would be salt and pepper. A little nutmeg and maybe some hot sauce would work well if you like it spicier.

Shredded Cheese– Any melting cheese is excellent for this recipe.

The most popular is, of course, cheddar cheese. Gruyere, mozzarella, and Mexican cheese work well. If you don’t like it very cheesy, add less. Not a big deal. However, it needs some cheese. This is not an ingredient to skip entirely.

Tip: Mix the cheese with the dried bread and keep a handful of cheese aside to sprinkle on top of the dish when you are ready to place it in the oven.

Some other possible ingredients:

Meat: Sausage/chorizo, bacon, ham, and other cold cuts are the most popular.

Vegetables: asparagus, peppers (I prefer the red, yellow, or orange), sun-dried tomatoes, scallions, white or red onion, mushrooms, leeks, spinach, etc. 

Note: Don’t add them all, just pick and choose the ones you have available in the refrigerator and go with them. Two to three veggies are just enough. Although they are not mandatory, having them in the mixture is nice.

Herbs: thyme, marjoram, rosemary, dill, etc.

Spices: nutmeg, mustard powder

Some of my favorite combinations for strata would be: 

  • Ham and green onion
  • Ham or bacon, green onion, pepper, and sun-dried tomatoes
  • Spinach, bacon, and red onion
  • Ham and spinach
  • Mushrooms, green onions, and dill
  • Bacon and leeks
  • Asparagus, sun-dried tomatoes, and green onion

Assemble the strata:

In a baking dish, place the bread on the bottom and add the shredded cheese, chopped meat of your choice, and vegetables, also chopped small.

Add the mixture of milk/eggs and top the dish with more shredded cheese. Cover with foil and place in the refrigerator for a few hours or overnight.

Overnight is better because the ingredients will have time to get friendly with each other. Friendly ingredients = delicious dish!

Unbaked Strata

Bake it

The following day, preheat the oven to 350F/180C and place the dish inside. Bake the dish for about 40 minutes and check the inside. It is ready if it doesn’t jiggle when shaken. The dish should be golden brown on top, and the cheese should be melted. 

You can also ensure it is cooked by checking the internal temperature in the center. It has to be 160F

Remove it from the oven and let it sit for 5-10 minutes. While baking, the strata will puff up, but after you remove it from the oven, it will deflate.

Note: If the dish was at room temperature, it might need only 40-45 minutes to bake. If the dish was super cold, it might need another 5-10 minutes. The dish should reach 160F inside to make sure the eggs cook inside. Check and make sure you don’t overcook it!

Why does strata have to sit overnight?

A delicious strata needs some time to sit uncooked until the bread has the time to absorb some of the custard. However, eggs, milk, and other ingredients in this baked egg casserole are perishable. You must keep the assembled dish in the refrigerator at all times until it goes into the oven.

How far ahead can you make strata?

Make this dish up to 12 hours ahead of baking. If you forgot to assemble the dish the night before, allow it at least one hour on the day you plan to bake it, so it has some time to absorb the liquid and do its magic.

What is the difference between strata and frittata?

Strata is a baked egg casserole with layers of bread, custard, cheese, and other ingredients, like meat and/or vegetables.

A frittata is an egg dish made with eggs, meat, and veggies, cooked in a skillet, then finished in the oven.

Can I make a dairy-free strata?

Yes, use dairy-free milk or cream instead of the regular one.

Can I freeze unbaked strata? 

Basically, you can freeze almost anything. However, I am not a fan of freezing eggs. First of all, the texture will change and become rubbery when frozen. I know people will probably say I am wrong, but this is my opinion. is very clear about this as well.

How to store leftovers strata:

After baking, leftovers should be refrigerated within two hours and kept in the refrigerator for up to four days. You can also freeze already baked strata for up to three months.

You can serve leftovers hot or at room temperature for breakfast, brunch, or lunch, next to a beautiful salad.

Do you think this would work with yogurt instead of sour cream?

I think you can use yogurt. I personally never tried it, but if you do, please come back and report. You made me curious. :-)

Hi. Can I freeze portions of the cooked dish for my kids

Cooked strata can be frozen for up to three months.

This looks amazing! With milk and eggs always available, I love recipes that allow me to use whatever ingredients I have in the fridge that are left forgotten, bread included. I'm going to try this for sure but I'd like to know one thing before I do. If I wanted to reduce the amount by half, do you believe the cooking time must also be reduced? Thanks in advance!

Hi, half of a 9x13inch pan is an 8x8inch. Use the same temperature, 350F, but check the dish after 25 minutes.
