How to Make Sausage Breakfast Casserole

1. Heat the Oil: In a large frying pan over medium-high heat, warm the olive oil until shimmering. Remove the casings from the pork sausage if necessary and add it to the pan, cooking until it s browned, about 4 to 7 minutes. Then, set it aside to cool slightly.
2. Prepare the Baking Dish: Coat your 9×13-inch baking dish liberally with cooking spray or a drizzle of olive oil. This will keep your casserole from sticking and make clean-up a breeze!
3. Whisk the Egg Mixture: In a large bowl, combine the eggs, half-and-half, dry mustard, kosher salt, and black pepper. Whisk everything together until well blended, creating a rich custard base for your casserole.
4. Add Cheese and Bread: Grate the sharp cheddar cheese and cut the white sandwich bread into 1-inch pieces. Stir half of the cheese (1 cup) and all of the bread into the egg mixture, ensuring every piece is coated.
5. Incorporate the Sausage: Using a slotted spoon, gently add the cooled sausage into the egg mixture. Fold everything together gently until evenly combined, then pour it into the prepared baking dish. Sprinkle the remaining cheese on top.
6. Chill or Bake: Cover the dish and let it refrigerate for at least 8 hours or up to 24 hours for the best flavors. Alternatively, you can bake it right away and let it sit while the oven preheats.
7. Bake to Perfection: Preheat your oven to 350 °F and arrange a rack in the middle. If the casserole was refrigerated, let it sit out at room temperature while the oven heats. Bake uncovered for 50 to 55 minutes, or until the top is golden-brown and a knife inserted in the center comes out clean.
8. Cool and Serve: Allow the casserole to cool for 10 minutes before slicing it into generous portions. Enjoy the warm, cheesy goodness with your loved ones!

Optional: Serve with fresh fruit or a dollop of sour cream for added zest.
