California Breakfast Casserole

California Breakfast Casserole
This California Breakfast Casserole is delicious!!  It is easy to make and will please your breakfast guests of all ages!  We like to top it with sour cream and salsa.

California Breakfast Casserole
  • 12 precooked (frozen) breakfast sausage patties, thawed
  • 2-3 sliced tomatoes
  • 2-3 sliced avocados
  • 12 eggs
  • 1 c. milk
  • 1 pkg. frozen hash browns, thawed
  • 1 c. cheddar cheese (shredded)
  • 1 tsp. salt
  • ½ tsp pepper
  • extra cheddar cheese for topping
  1. Layer the bottom of a greased 9x13 pan with sausage topped with tomatoes and avocado.
  2. In a bowl, beat eggs and milk. Stir in all other ingredients. Pour hash and egg mixture over the sausage, tomatoes, and avocados.
  3. Bake at 350 for 35-45 min or until well set. Top with extra cheddar right after pulling out of the oven so it melts all over the top. Top with salsa or sour cream.


  1. When you say you prepare the night before does that mean that you just assemble and let sit overnight in the fridge or do you bake it the night before and reheat in the morning?

    • You can assemble it and let sit overnight without baking. That way it tastes fresh when you bake it up the next morning.

  2. Im cooking this recepie but is taking a while to cook, i already add two times 20 mis, i dont know if we need to use a especific type of pyrex, i used a round corning ware dish .

    • I am using a 9×13 in. glass dish. It has already cooked for one hour and it is still liquid egg mixture all the way through! I am NOT happy!

      • We usually use a ceramic 9×13 pan because it seems to heat better. It also depends on your elevation. Give it another 20 minutes or so. I am so sorry!

  3. Making this tonight for tom morning..was wondering if you could use simply potatos hash browns that are not frozen? Thanks!

  4. Just made this and after cooking 40 minutes, it looked done. When I cut it there was liquid at the bottom. The eggs looked cooked. Could the liquid be from the tomatoes? Maybe if I assemble and let i sit overnite? Thanks.

  5. In the picture it looks like there is another layer of something underneath the sausage. If so, what is in the layer?

    Thank you

    • Some of the egg mixture seeps down underneath the sausage making it look like another layer.. but the first layer you put down is the sausage.

    • You would have to plug it in to a recipe calculator to find the nutritional info. But eggs have a high cholesterol content, so if you are watching that, I would sub the eggs for an egg substitute (the kind that comes in a carton). I have used those in an egg casserole before and it turned out great!

  6. I made this for friends this week when we were away on vacation and it was a hit. I made it in a glass 9×13 pan and it took an hour to cook. When I got home my husband was jealous that I made it for friends so I made it for us at home again today. He LOVED it. Keeper recipe, thank you! I’m glad to see in the comments here that it can be assembled the night before. Looking forward to hearing if anyone freezes it.

    • So glad to hear you liked it! We have assembled it the night before as well and it is great– just haven’t done the freezing thing. Let us know if you try it and how it turns out!

  7. I am getting ready to make this, this morning for Thanksgiving! Thank you for the recipe, hope it turns out as good as yours looks! :)

  8. I finally made this dish and it was DELICIOUS. I added a twist to it, I added spinach and I used Italian sausage and chorizo. I excluded the guacamole in the mixture but did add to the final product along with jalapeños, salsa and sour cream. Thanks for sharing

  9. One question ? The recipe start with sausage on the bottom and the picture is displaying a layer of something before the sausage is laid. What is the layer before the sausage. t Than

  10. A few adjustments are needed here in my opinion. First of all, adding an entire cup of milk is far too much. It causes the dish to have excess liquid which can make for an unpleasant texture. It makes it seem as if the eggs are still raw. Also I made a base layer of crushed up tortilla chips, using just sausage is a bit awkward when trying to plate. And speaking of sausage, precooked sausage isn’t the best for you. So I opted to use shredded chicken breast! It makes the dish heartier and not as fatty! As for produce, I used Roma tomatoes (for their AMAZING flavour), added white onions, red bell peppers, and jalapeños on one half. My hubby can’t get enough of those! All in all, good idea for a dish. Just needed some tweaking to make it truly fantastic!

  11. Something is not right. That photo looks like it has a crust of some kind under the sausage. And it’s not cooked eggs. You can tell from the photo the crust is separate and distinct from the sausage layer.

    • It looks like there is a crust but there is not. It is egg that has seeped beneath the sausage layer. This is the same recipe as the one pictured. Hope this helps!

  12. I first had this at a baby shower & it was great! However, it took TWO hours to cook in a 9×13 metal pan when I baked it for a potluck today! Luckily I allowed extra time or I’d have gone dishless! Hoping the tomatoes & avocados held up!
