An Easy Breakfast Casserole
Is there anything better than a recipe that’s not only easy to make and great for busy days, but also great for guests? That’s what we are going for with this croissant breakfast casserole with prosciutto!
With 5 ingredients, it can be whipped up quickly and it’s ready in just 20 minutes. The ingredients are – buttery croissants, cherry tomatoes, prosciutto, eggs, and cheese – but maybe a bit “fancier” than you might normally make for breakfast. (Prosciutto just seems classier to me than bacon or ham!) That means it’s perfect for a weekend breakfast when you just want something more than your basic omelette or oatmeal, but equally as perfect for a nice breakfast or brunch with friends.
This croissant breakfast recipe is also a great way to perfectly cook several eggs at a time, without scrambling them or making an omelette. I know that when I’m cooking breakfast for several people I don’t always want to be at the stove individually frying eggs, so this is a great alternative. Just a few minutes to assemble the casserole and hands-off until it’s ready!
What You’ll Need
These skillet baked eggs are made with just 5 ingredients! Simple and easy with a presentation that makes it perfect for brunch guests.
- Croissants – Buttery, flaky croissants fresh from the bakery section of the grocery store are the best option!
- Eggs – The eggs get cooked to perfection during baking.
- Cherry tomatoes – I use yellow cherry tomatoes, which are little sweeter than the popular red variety, but red works just fine.
- Prosciutto – A salty and well-seasoned Italian classic! I think using prosciutto gives this dish a fancy flair.
- Thyme sprigs – Fresh thyme adds flavor and a pop of color.
- Sea salt and black pepper – Added to taste.

How to Make Croissant Breakfast Casserole
The great thing about these skillet baked eggs is how easy they are to prepare! You just need about 5 minutes to assemble the casserole and 10 to 20 minutes of bake time before breakfast is served.
- Preheat the oven to 375 F and prepare the pan by greasing with a bit of olive oil or nonstick cooking spray.
- Assemble the breakfast casserole. Cut the croissant in half and place in the cast iron pan, then crack the eggs on top of the croissants. Add the cherry tomatoes then top with parmesan all over. Finish by tucking in the prosciutto and arranging the thyme.
- Bake. Place on the middle oven rack and bake until the croissants are golden brown and the eggs are set to your liking, about 10 to 20 minutes.
- Serve. Top with salt and pepper and serve immediately.
How Long Does It Take To Cook Baked Eggs?
The cooking time for this croissant breakfast recipe will depend on how you like your eggs. For a runny yolk, you’ll only need to bake this for about 10 minutes and can remove the pan from the oven as soon as the whites have set. For a firmer yolk, allow a few extra minutes. I’ve found that even for fully cooked eggs with a hard yolk, you only need a maximum of 20 minutes.
I recommend to start keeping an eye on your eggs at around the 8 minute mark, especially if you like a soft yolk.
Breakfast Croissant Casserole Variations
If you like to get creative with your recipes or maybe you’re just not a fan of one of the listed ingredients, here are a few easy variations on this croissant breakfast recipe!
- Swap the prosciutto. If you don’t have prosciutto on hand, you can easily replace it with deli ham, fully cooked sausage or fried bacon.
- Add more cheese. While the flavors of prosciutto and parmesan pair together well, you can also use a soft gouda, gruyere, mozzarella, or cheddar cheese in this recipe.
- Use your favorite herbs. Any fresh herbs, dried herbs, or green onions, will work with these baked eggs so feel free to adjust according to your flavor preferences.
- Serve it up with something creamy. Avocados, cream cheese, and dijon mustard are all great additions.
Serving Suggestions
Enjoy this delicious breakfast casserole immediately after removing it from the oven. Top with some crunchy sea salt and cracked pepper, or drizzle with your favorite hot sauce and enjoy! The warm, soft yolks (if you like your eggs that way) are perfect for dipping the croissant.
One thing I love about this easy breakfast bake is that there’s no need to make any additional dishes – with the croissant, eggs, and prosciutto it’s a full breakfast in one dish. Add a cup of coffee or a mimosa and you have a delicious breakfast or brunch. You could also add a fresh fruit salad or fresh berries for at Sunday brunch, Christmas morning breakfast, baby showers, or Easter brunch.
How to Store Leftovers
This croissant breakfast casserole with prosciutto is best when served immediately. This is especially true if you like your eggs undercooked. That said, you can refrigerate this skillet breakfast bake for up to 3 days. Store in an airtight container and reheat completely in the oven, or airfryer. The microwave works, but can make for rubbery croissants if you over do it.
A word of caution – do not freeze this breakfast casserole. It’s best to enjoy it fresh every time. The croissant will not taste good after defrosting and soft eggs will not have the right texture if frozen and defrosted.
This dish is quick and easy to make, so whipping it up fresh is no problem at all. This sweet croissant breakfast casserole is the best breakfast casserole and sure to become one of your favorites as well.
