Easiest Breakfast Casserole Recipe: Step-by-Step Guide

Ready to get cooking? Follow these simple steps to create your Easiest Breakfast Casserole:
Step 1: Prepare the Puff Pastry
Start by preheating your oven to 375°F (190°C). Roll out the thawed puff pastry on a lightly floured surface if necessary. Place it into the greased 9×13 inch baking dish, pressing it into the corners and up the sides to form a crust.
Step 2: Whisk the Eggs
In a mixing bowl, crack the 10 large eggs. Add the 2/3 cup of half & half and whisk them together until fully combined. The half & half adds creaminess to the eggs, making them fluffy and rich.
Step 3: Add Flavor
Stir in the packet of Hidden Valley Ranch Dip Mix to the egg mixture. This is the secret to the dish’s incredible flavor. The ranch seasoning gives the casserole a delightful kick that pairs perfectly with the cheese.
Step 4: Cheese It Up
Add the 1 1/2 cups of shredded cheddar cheese to the egg mixture, and gently fold it in until evenly distributed. The cheese will melt beautifully while baking, creating a gooey and delicious filling.
Step 5: Pour and Bake
Pour the egg and cheese mixture over the puff pastry in the baking dish. Spread it out evenly, ensuring the filling is well-distributed. Place the casserole in the preheated oven and bake for 30-35 minutes, or until the eggs are set and the top is golden brown.
Step 6: Let Cool and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes before slicing. This will help the layers set a bit more, making it easier to serve. Cut into squares and enjoy warm!
Dietary Swaps & Alternatives
If you’re looking to customize your casserole to fit certain dietary needs, here are some great alternatives:
- For a lighter option, you can use egg whites instead of whole eggs.
- Swap the half & half for almond milk or oat milk for a dairy-free version.
- Try different cheese varieties, such as pepper jack or mozzarella, for a flavor twist.
- Add vegetables like spinach, bell peppers, or mushrooms for extra nutrition.
Don’t Do This
- Don’t skip the ranch dip mix; it’s essential for flavor!
- Avoid over-baking the casserole, as this can lead to dry eggs.
- Do not attempt to use a different type of pastry; puff pastry is key for that flaky crust.
- Don’t forget to grease your baking dish to prevent sticking.
Freezer-Friendly Notes
This casserole is incredibly versatile when it comes to storage. Here are some tips for freezing:
- Allow the casserole to cool completely before freezing.
