Ingredients for the casserole

  • Bread- Crusty bread works really well, preferably a day-old bread. Unlike regular sandwich bread, these hold their shape without turning mushy. Especially for overnight casseroles, when the mixture is rested overnight, the bread pieces soak up the liquid making the casserole fluffy and soft.
  • Breakfast sausage– makes the casserole more filling and wholesome. You can skip this if you wish.

  • Egg- of course, there are eggs. Go for fresh, free-range large eggs.
  • Half and half – While heavy cream is a bit too rich, half and half works perfectly in this recipe. For a lighter version, you can also use milk.
  • Seasoning – Italian seasoning, dijon mustard, salt and pepper.
  • Red bell pepper- You can use any colored pepper or a mix of all.
  • Cheddar – Mild cheddar.
  • Fresh parsley to garnish on top

How To Make Breakfast Casserole?

Making Breakfast casserole is easy. Cook sausage until it is no longer pink. Let the sausage cool down a bit before adding it to the eggs. Cut bread into 1 – 1.5 inch pieces. Beat eggs along with Italian seasoning, dijon mustard, salt and pepper. No need to cook the bell peppers separately, as they will be cooked along with the eggs.

After adding half & half, chopped bell pepper, and 1 cup cheese, give everything a good mix. Then fold in the bread pieces. If you are planning to right away, I would still suggest covering and letting the bread mix rest for 20-25 minutes for the bread to soak up the liquid. Then bake as per the recipe instructions below.

If you are planning to make it the next day, tightly cover the mixture with cling wrap and refrigerate overnight. Remove the mix while you are preheating the oven. Then bake as usual

6 easy steps to make overnight breakfast casserolePin


You can add other ingredients as per your taste and preference. Here are a few additions I love to do

  • Add veggies like mushrooms, spinach, broccoli, or zucchini. Cook the veggies and drain any extra liquid before adding them to the casserole. I would stick to 2-3 kinds of veggies, without overloading the casserole.
  • You can add crispy cooked bacon to it, as it adds great flavour.
  • If you have leftover cooked ham, substitute for sausage.
  • Pepper jack, and gouda are great alternatives to cheddar cheese.

Storing the leftovers?

It tastes great when immediately out of the oven and still warm. But the leftovers can be stored for up to 4 days in airtight containers in the refrigerator. So it is great for meal prepping.
