Italian Sausage Egg Casserole is simple, but extraordinarily flavorful and cheesy.  The simple trio of aromatics, onion, peppers and garlic, mingled with the seasonings from the sausage provide a delicious balance of savoriness.  The fried potatoes on the bottom add wonderful texture to the fluffy, tender eggs.


Units Scale
  • 12 eggs
  • 1/2 cup milk
  • 1 lb. mild Italian sausage
  • 1 small red onion, minced
  • 1/2 red bell pepper, minced
  • 1 Tablespoon garlic, minced
  • 1 large baking potato (or 2 medium), peeled and grated
  • 4 Tablespoons butter
  • 8 oz. Colby Jack or sharp Cheddar cheese, grated (about 2 cups)
  • salt and pepper, to taste


  1. Preheat oven to 350°.
  2. Brown sausage with onions, peppers and garlic over medium heat.  Break into small crumbles as it cooks.
  3. When sausage is done, move it and the cooked veggies to a bowl, leaving any rendered fat in the bottom of your skillet.  That fat is full of flavor.
  4. Add ¼ cup (half a stick) of butter to the fat in the skillet and melt it over medium high heat.
  5. Add the grated potato to the skillet, spreading it in a thin even layer.  Sprinkle with salt and pepper.  Continue cooking over medium high heat until the potatoes are crisp and brown on the bottom.
  6. Use a turner and flip the potatoes over, in sections.  Spread them out in the skillet, again, so you have an even layer.  Continue cooking on medium high heat for two minutes.
  7. Add the sausage and veggies back to the skillet in an even layer.
  8. Whisk the eggs and milk and add a little salt, pepper and/or seasonings of your choice.  Pour the egg mixture over the sausage and potatoes.
  9. Sprinkle with the cheese and bake at 350° for 30 – 40 minutes or until eggs are set.
  10. Cut into 12 wedges and serve.


I love a dollop of sour cream with some chopped tomatoes and green onion with my frittata.  It’s also perfect served with Homemade Biscuits, pancakes or waffles.  Add a green salad and some fruit and you’ll have a balanced and over-the-top delicious breakfast, brunch or breakfast-for-dinner menu.
