Your Shopping Guide

When preparing to make this casserole, make sure you have the following ingredients on your shopping list:
- 1 lb sausage: Choose your favorite type, whether it’s spicy, mild, or even turkey sausage for a lighter option.

- 2 cups milk: Whole milk or 2% will provide the creaminess needed.
- 8 large eggs: A key ingredient for binding everything together.
- 1 cup refrigerated sour cream French onion dip: This adds a rich flavor and creaminess that’s hard to beat.
- Salt and pepper: Essential for seasoning.
What You’ll Need (Gear)

Before you start cooking, gather the following kitchen tools:
- Large mixing bowl: For whisking eggs and combining ingredients.
- 9×13-inch baking dish: The perfect size for this casserole.
- Whisk: To ensure your eggs are thoroughly beaten.
- Skillet: For cooking the sausage until browned.
- Spatula: For mixing and spreading your casserole ingredients evenly.
Directions: Sausage Egg Breakfast Casserole
Step 1: Prepare the Sausage
In a skillet over medium heat, cook the sausage until it is browned and cooked through, breaking it into small pieces as it cooks. Drain any excess fat and set aside to cool slightly.
Step 2: Mix the Egg Base
In a large mixing bowl, whisk together the eggs, milk, sour cream French onion dip, salt, and pepper until well combined.
Step 3: Assemble the Casserole
In the baking dish, layer the cubed French bread evenly across the bottom. Sprinkle the cooked sausage over the bread, followed by a generous layer of Cheddar cheese.
Step 4: Pour the Egg Mixture
Pour the egg mixture evenly over the layered bread, sausage, and cheese. Make sure all the bread is soaked in the egg mixture. Press down gently with a spatula to ensure everything is well distributed.
Step 5: Refrigerate and Soak
Cover the dish with plastic wrap and refrigerate for at least 30 minutes or overnight. This allows the bread to absorb the egg mixture, resulting in a fluffy and flavorful casserole.
Step 6: Bake
Preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature for about 10 minutes. Bake uncovered for 45-50 minutes, or until the top is golden brown and the eggs are set.
Step 7: Serve and Enjoy
Allow the casserole to cool for a few minutes before slicing. Serve warm, garnished with fresh herbs if desired.
Seasonal Ingredient Swaps
If you’re looking to mix things up or use seasonal ingredients, consider these swaps:
- Vegetables: Add sautéed spinach, bell peppers, or mushrooms for extra nutrition and flavor.
- Cheese: Swap Cheddar for pepper jack for a spicy kick.
- Meat: Use cooked bacon or ham instead of sausage for a different flavor.
- Herbs: Fresh chives or parsley can be added for a fresh finish.
