Ingredients
  

  • 1 lb breakfast sausage (mild or spicy – your choice)
  • 1 tbsp dried minced onion (or ½ cup finely chopped fresh onion)
  • 12 large eggs
  • ¾ cup whole milk
  • 1 tsp salt
  • ¼ tsp ground black pepper
  • 1 cup grated sharp cheddar cheese, divided

Optional additions:

  • A handful of chopped spinach or bell peppers
  • A pinch of crushed red pepper flakes
  • Hot sauce or salsa for serving

Instructions
 

Step 1: Brown the Sausage

  • In a skillet over medium heat, brown the sausage, breaking it apart with a spoon. When nearly cooked through, add the minced onion and sauté until the sausage is browned and fragrant. Drain any excess grease.

Step 2: Whisk the Egg Mixture

  • Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
  • Spread ¾ of the cooked sausage on the bottom. Sprinkle half the cheese evenly over the sausage, then pour the egg mixture on top.

Step 4: Bake

  • Place in the oven and bake for 30 minutes, or until the eggs are mostly set.
  • Remove the dish, top with the remaining cheese and sausage, then return to the oven for another 10–15 minutes, until the top is golden and bubbling.

Step 5: Rest and Serve

  • Let the casserole rest for 5 minutes before slicing. Serve warm with biscuits, toast, or fresh fruit. (And if you’re like most Southerners—don’t forget a dash of hot sauce.)
