Traditionally you can make Breakfast Casserole ONLY with eggs, hash browns and sausage. It’s also frequently made with ham and cheese. While the original style is great, I simply like to add spinach and caramelized onions to make it taste even better!
HOW TO MAKE BREAKFAST CASSEROLE:
- The first step is to defrost your hash browns the day before. You will move them from the freezer to refrigerator the night before. That they they will be ready to go on the morning when you need them.
- You will start by caramelizing your onions. Stirring constantly for about 5 minutes just to let the onions soften. You will also want to deglaze with a splash of water at the end.
- Then you will add sausage and cook it in the pan.
- The next step will be to add spinach. It will wilt quickly in the hot skillet.
- After that you will add your defrosted hash browns and stir them in.
- Once you warm up those hash browns, you will add cheese.
- Transfer the mixture to the prepared 8×8 casserole dish.
- Lastly, add milk and eggs mixture right into the casserole dish.
Breakfast Casserole Tips
- You will bake it at 375 F for at least 40 minutes. However, you might have to keep it in the oven even longer than that. You’ll have to check center of your breakfast casserole will be done. So you will cook it anywhere from 40 minutes to 1 hour.
- Note that it is best to use only ½ cup of milk so that your breakfast casserole is not runny. I do not recommend using more than that for this recipe.
- The cheese and eggs will thicken this dish up. If you like to use more cheese, allow the sauce to stand for 2-3 minutes before serving.
Equipment Needed
You will need a glass 8×8 casserole dish. You can also use 9×9 or 9×13 dish.
