Preparing The Ultimate Overnight Breakfast Casserole

Gather Your Ingredients

To make The Ultimate Overnight Breakfast Casserole, you’ll need the following ingredients:

• 1 pound breakfast sausage
• 1 package frozen hash browns (about 30 oz)
• 8 large eggs
• 1 cup milk
• 1 cup sour cream
• 2 cups shredded cheddar cheese
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/4 cup chopped green onions

For variations, consider swapping out the sausage for turkey or plant-based options, or mix in your favorite vegetables for added flavor.

Step-by-Step Directions

1. Cook the Sausage: In a skillet over medium heat, cook the breakfast sausage until browned. Once cooked, set it aside to cool.

2. Prepare the Egg Mixture: In a large bowl, whisk together the eggs, milk, sour cream, salt, and pepper until the mixture is smooth.

3. Layer Your Ingredients: Grease a 9×13 baking dish. Start by layering half of the hash browns, followed by half of the cooked sausage, and a generous layer of cheese. Repeat with the remaining ingredients.

4. Add Egg Mixture: Pour the egg mixture evenly over the top of the layered ingredients.

5. Refrigerate Overnight: Cover the dish with foil and place it in the refrigerator overnight.

6. Bake the Casserole: In the morning, preheat your oven to 350°F. Bake the casserole, covered, for 45 minutes. Then, remove the foil and bake for an additional 20–25 minutes until it is golden and fully set.

7. Garnish and Serve: Top with chopped green onions and serve warm.

Perfect Pairings for The Ultimate Overnight Breakfast Casserole

This casserole stands beautifully on its own but can be enhanced with a variety of sides. Consider serving it with fresh fruit for a refreshing contrast, or pair it with crispy bacon for extra protein. You can also offer a light salad or some fluffy biscuits to round out the meal.

Storage and Reheating Tips

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, you can freeze portions for up to 3 months. To reheat, simply cover with foil and warm in the oven at 350°F until heated through. Always ensure to handle food safely to avoid any spoilage.

Pro Chef Tips

• Pre-Cook the Ingredients: For even more flavor, consider pre-cooking any vegetables you want to add, such as bell peppers or mushrooms.
• Cheese Variations: While cheddar is delicious, try mixing in Swiss or pepper jack for a different flavor profile.
• Add Spices: A pinch of cayenne or a dash of hot sauce can spice things up if you like a little kick!

Creative Twists

Feel free to get creative! Swap out the hash browns for tater tots or even diced bread for a completely different texture. Add cooked spinach or sun-dried tomatoes for a unique flair, or consider using different meats like ham or chorizo.
