How to Make Crockpot Christmas Breakfast Casserole
- Prep: 20 minutes
- Cook: 6 hours on Low or 3 hours on High
- Total: about 6 hours 30 minutes on Low
- Brown the sausage over medium heat for 6 to 8 minutes, breaking it up as it cooks. Drain excess fat if the skillet looks greasy.
- Add onion and bell pepper to the skillet and sauté for 3 to 4 minutes until they soften and pick up some color.
- Whisk eggs, milk, salt, pepper, garlic powder, dry mustard, and smoked paprika in a large bowl until smooth.
- Spray the slow cooker generously. Spread half the hash browns in the bottom, then sprinkle half the sausage, half the veggies, and half the cheeses. Add spinach if you use it. Repeat the layers with the remaining hash browns, sausage, veggies, and cheeses.
- Pour the egg mixture evenly over the layers. Gently press down with a spatula so the eggs seep through.
- Cover and cook on Low for about 6 hours or on High for about 3 hours. Cook until the center sets and reaches 165 F. The edges will look puffed and lightly browned.
- Turn the slow cooker to Warm. Rest the casserole for 10 to 15 minutes so it slices neatly. Top with green onions and serve with salsa or hot sauce.
Tips & Tricks
- Line or coat the crock generously so slices lift clean.
- Keep condensation off the surface by laying a clean kitchen towel under the lid. Re-secure the lid so it fits snugly.
- Use frozen hash browns for convenience or thaw them if you want a slightly drier bite.
- Build flavor with seasoned sausage, smoked paprika, and sharp cheddar.
- Need meat-free? Swap sausage for sautéed mushrooms and extra spinach, and add a pinch of fennel and paprika.
- Add cooked bacon or diced ham in place of sausage for a different vibe.
- Set a programmable slow cooker to switch to Warm when it hits time.
- Avoid a soggy texture by resisting the urge to lift the lid early.
- Cooking for fewer people? Halve the ingredients and use a 4 quart cooker. Start checking 30 to 45 minutes earlier.
What to Serve with Crockpot Christmas Breakfast Casserole
This slow cooker breakfast pairs nicely with a bright fruit salad and a simple arugula citrus salad. Add warm biscuits, English muffins, or cinnamon rolls for the carb fans. Pour coffee, tea, or a brunch mocktail, and pass hot sauce for the spice lovers. A bowl of yogurt with granola rounds out the spread and adds a cool, creamy contrast.
Make-Ahead and Storage
- Assemble and chill: Load the insert with all layers and egg mixture up to 12 hours in advance if your insert allows refrigeration. Let the cold insert sit on the counter 20 to 30 minutes before heating to reduce thermal shock.
- Cook ahead: Chill leftovers in a covered container for up to 4 days. Freeze portions for up to 2 months. Wrap pieces tightly to prevent freezer burn.
- Reheat: Microwave single servings for 60 to 90 seconds until hot. Or reheat a covered dish in a 325 F oven for 15 to 20 minutes. From frozen, thaw overnight or reheat covered at 300 F for 30 to 40 minutes.
