What Goes with a Puff Pastry Breakfast Casserole?

There are so many things you can serve with your puff pastry breakfast casserole. I like to serve it with a side of fruit, like strawberries or blueberries. A fruit smoothie is another easy idea. It's also delicious with a side of roasted potatoes or hash brown. And, of course, no breakfast is complete without a hot cup of coffee.

You can also add more bacon on the side because no one has ever said there was too much bacon. If you are someone who loves to pair eggs and bacon with french toast, you can add a serving of his brioche French toast casserole alongside the casserole.

How to make a Puff Pastry Bacon and Egg Casserole

Video Instructions:

Before you begin, you will need to cook the bacon, drain it, crumble it then set it aside. This is great for leftovers from another breakfast. Then, you will want to preheat the oven to 350°F/180°C.

Spray the bottom of the baking dish with non-stick spray. I used a 9" square dish, but you can use a larger one if you prefer. Then, roll out the puff pastry, and cut it in half creating two squares. Place one of these squares into the base of the baking dish, then cut the other half into ½" strips and set them aside.

Over medium heat, add the olive oil and onions to a large skillet and cook for 5 minutes, stirring regularly. They should be softened and just starting to brown.

Then, add in the creamed spinach. I used a frozen package that had been thawed and patted dry. You can use any you already made if desired. Then, stir it and the onions together.

Pour the cooked spinach mixture into a large bowl. I recommend letting it cool for 5 minutes, and then stir in the cheese and cooked chopped bacon. Now, add 5 of the eggs and stir until this is all combined well.

Pour this into the prepared baking dish.

Then top with the strips of puff pastry.

Frequently Asked Questions

Can I Add Different Proteins to My Egg Casserole?

Bacon and eggs are a classic, but you can add whatever protein you like to this casserole. Sausage or ham are also delicious ideas. If you live in an area with specialty breakfast meats, like scrapple, pork roll, or goetta, those would be amazing in this recipe as well.

If you're looking for a vegetarian option, tofu "bacon", mushrooms, or vegan sausage would work great. Just make sure to cook the protein before adding it to the casserole.

Do I Need to PreCook the Pastry?

One of the great things about making this bacon and egg casserole is that you do not need to precook the puff pastry. Anything that can save a step or two is always a win. As the bacon and egg casserole bakes in the oven, the puff pastry will cook and absorb some of the flavors of the casserole.

How Long is Bacon and Egg Casserole Good For?

This casserole is best enjoyed fresh. However, the leftovers can be enjoyed for up to 4 days. When it is time to reheat the casserole, I like to reheat only the amount that will be eaten at the moment. Be sure to heat it all the way through. Reheat the bacon and egg casserole in the oven or microwave.

Can I Freeze Puff Pastry Breakfast Quiche?

Yes, you can! This is very similar to a traditional quiche and is easy to freeze. I recommend freezing it after baking for the easiest preparation when ready to serve, however, you can freeze it just before the baking portion of the recipe. Just wrap it well with plastic wrap, then aluminum foil, label it, and date it. It stays fresh for up to 3 months in the freezer.

To prepare from frozen, let it thaw overnight in the refrigerator before placing into the oven and baking as directed in the recipe.
