Why This Dish Shines

How to Make Overnight Holiday Breakfast Casserole

Step 1 Preheat your oven to 350°F. Grease a 9×13 baking dish well. This stops the eggs from sticking later. Use nonstick spray or butter for best results. Step 2 Cook sausage in a skillet until browned. Add garlic for extra flavor. Drain grease on paper towels. (Hard-learned tip: Pat sausage dry to avoid a greasy casserole.) Step 3 Whisk eggs and milk in a big bowl. Stir in potatoes, spinach, and ½ cup cheese. Add the cooked sausage last. Season with salt and pepper. Step 4 Pour mix into the dish. Top with leftover cheese. Bake 45 minutes until eggs set. Cover with foil if the top browns too fast. Step 5 Let it rest 10 minutes before slicing. This helps it hold its shape. Serve warm for the best taste and texture. What’s the best way to store leftovers? Share below! Cook Time: 45 minutes Total Time: 55 minutes Yield: 15-18 servings Category: Breakfast, Holiday
