This overnight breakfast casserole chock full of vegetables, sausage, chorizo and brioche is an incredible time saver and such a treat. Make it this holiday season!
Breakfast is the most important meal of the day they say. I am not here to tell you whether it’s true or not. I am however, here to make it the most delicious meal of the day with my overnight breakfast casserole.
Whether you are a morning person or not, we can all agree, it brightens our a day quite a bit when we start with a tasty and nutritious breakfast.
The trouble is who wants to get straight into cooking first thing in the morning? Not this girl! It takes me a good half hour to wake up.
So the most reasonable solution is to get your breakfast ready the night before, which is especially handy when you cook for a crowd! Or when you want to make a special breakfast for a Christmas morning.
Ingredient Options Breakfast Casserole
Here is a list of ingredients for a savoury, egg-based dish.
- bread (I used brioche but other white bread will work equally well)
- sauteed onions, red peppers and mushrooms with a touch of garlic
- green onions and parsley
- a mix of two cheeses (White Cheddar and Red Leicester) but you can use any cheese you love
- Worcestershire sauce, Dijon mustard and a dash of Spanish paprika to take flavours up a notch
Recipe Tips and Notes
The base of the breakfast casserole recipe I am sharing today is egg and brioche loaf. Everything else is extra, delicious, flavour-giving extra.
What I added to my breakfast dish are the ingredients my family loves but they could be easily swapped for your personal favourites.
The beauty of this breakfast casserole, apart from its delicious flavour, is the convenience. You can slice, sauté and assemble the casserole the night before, cover it and refrigerate overnight.
All is left to do in the morning is to take the cover off and bake it in the oven until the centre is no longer jiggly, which will take between 50-60 minutes at 350F/180C.
It also reheats beautifully either in the microwave or an oven if you end up with any leftovers.

- To the same frying pan add chopped onion, red bell pepper and cook over low heat for 5 minutes, then add mushrooms, a pinch of salt and Spanish paprika and continue cooking until mushrooms are done and the liquid has evaporated, then add minced garlic clove and cook for 20-30 seconds. Combine with the cooked sausages and chorizo.

To the bowl with the meat and vegetables, add the the cubed brioche, green onions, parsley and both cheeses and gently mix everything together. Then transfer the mixture into a buttered 13X9 inch casserole dish and pour the egg mixture over it. Cover with aluminium foil and refrigerate overnight.
