Ingredients
- Bread
- Sausage
- Olive oil
- Italian seasoning
- Onion
- Garlic
- Bell peppers
- Eggs
- Cottage cheese
- Milk
- Cheese
Directions
Cube the bread into small, bite-sized pieces. Chop up the onion and bell peppers and mince the garlic. Grate the cheese.
In a medium to large saucepan, heat the oil over medium heat and cook the vegetables (onion, garlic and bell peppers) until softened, about 3 minutes. Remove from the pan.
Then cook the sausage until no pink remains. Add the vegetables back into the pan and add the Italian seasoning. Turn off the heat and set aside.
Mix together the eggs, cottage cheese and milk.
Assemble the casserole by lightly greasing a 9×13 pan. Add a layer of the cubed bread. Then add a layer of the sausage/vegetable mixtures. Pour the egg mixture over everything. Then top with the cheese.
Cover and refrigerate overnight. You can refrigerate this uncooked casserole for anywhere from 30 minutes to 24 hours as needed. But I most often refrigerate for 8-10 hours, as I will make this the night before I plan to bake it.
Bake at 350°F (177°C) for 35-40 minutes. Top with a handful of chives or parsley if you like. Allow to cool for 10-15 minutes before slicing in it.
Tips for Making
- You can use any bread for this recipe. I most often use whatever I have on hand, so it’s usually sourdough or a honey wheat. You’ll only need 3-4 slices of bread.
- I like to mix the eggs, cottage cheese and milk in a blender so the cottage cheese really gets blended in. But you can also whisk by hand in a mixing bowl. Just make sure to break up the egg yolks well.
- You can substitute the sausage for another ground meat like beef or turkey if you like.
- If you want to add more vegetables to this, like mushrooms or zucchini, feel free!
- Save any leftovers by covering the casserole pan in plastic wrap or aluminum foil in the refrigerator for at least 3 days. Rewarm in the microwave.
