Not only is this dish incredibly easy to make, but you can actually make it ahead of time too! This is a perfect dish for any brunch – not just at Christmas! When we’re having a brunch, I like to serve something sweet to go along with it and this delicious Lemon Blackberry Bread definitely fits the bill.

Prep time: 10 minutes
Cook time: 45 minutes
Serves: 4
Ingredients:
Non-stick cooking spray
½ lb. bulk Italian sausage (no casings)
1 small red onion, diced
1 large russet or Idaho potato, diced
2 large eggs
3 T. whole milk
2 c. fresh broccoli, diced
¾ c. sharp cheddar cheese, shredded, divided
2 T. fresh chives, finely chopped
Sea salt and black pepper, to taste
Directions:
Preheat oven to 350°F and spray an 8 x 8-inch baking dish with some non-stick cooking spray.
Set a large skillet over medium heat and add the sausage. Cook until slightly browned, breaking up the sausage with a wooden spoon as it cooks, approximately 3-4 minutes.
Add the onion and potato and season with salt and black pepper, to taste. Cook, stirring occasionally, until the onion softens and the potatoes become golden brown, approximately 6-7 minutes.
In the meantime, whisk the eggs and whole milk in a small bowl and season with salt and black pepper, to taste. Add one-half cup cheddar cheese and stir to combine.
Transfer the sausage-potato mixture into the prepared baking dish and stir in the diced broccoli. Spread into an even layer and pour the egg mixture evenly over the top.
Sprinkle remaining cheese across the top. This is where you would cover the dish with plastic wrap and place it in the fridge until the next morning if making it ahead of time.
Place in the pre-heated oven and bake until the eggs are set and the potatoes are cooked through, around 30-35 minutes.
Remove from oven and cool for several minutes before slicing. Top with fresh chives and serve immediately. Enjoy!
Variations:
Use hash browns in place of the diced potatoes.
Add some chopped red pepper to the onions and potatoes. This adds a fun red touch to the recipe and along with the broccoli, makes for festive holiday colors.
Vary the type of cheese. You could even combine 2-3 kinds. Goat cheese, gouda, and swiss are all good options.
Use spinach in place of the broccoli.
