Step‑by‑Step Instructions for Savory Breakfast Croissants
Step 1: Whisk the Eggs
In a mixing bowl, crack and whisk together 5 eggs with a pinch of salt until the mixture is smooth and combined. This creamy base will provide rich flavor when incorporated into your Breakfast Croissants. Set the egg mixture aside while you prepare the mushrooms and other fillings.
Step 2: Sauté the Mushrooms
In a large frying pan, melt 2 tablespoons of butter over medium heat. Once melted, add approximately 150g of sliced mushrooms, spreading them out evenly in the pan. Cook them for about 5-7 minutes until they’re golden brown, flipping halfway through. In the last couple of minutes, add one minced garlic clove, along with salt and pepper to taste, then remove the pan from heat.
Step 3: Scramble the Eggs
Lower the heat to low, adding 1 tablespoon of butter to the same pan used for mushrooms. Pour in the beaten egg mixture and stir gently. This will create creamy curds as the eggs cook. Continue stirring for about 10-15 minutes until the eggs are soft, slightly runny, and velvety. Your Breakfast Croissants will be perfect with these creamy scrambled eggs!
Step 4: Prepare the Croissants
Preheat your oven to 180°C (350°F). While the oven heats, take your large, buttery croissants and slice them open gently on one side. Place them on a baking tray lined with parchment paper. Add slices of cheese—preferably Swiss or cheddar—to one side of each croissant, ready to melt as the croissants bake.
Step 5: Bake the Croissants
Once the oven has reached the desired temperature, place the tray with the croissants inside. Bake for approximately 5 minutes or until the cheese has melted beautifully and the croissants are warm and flaky. Keep an eye on them to avoid over-browning.
Step 6: Assemble the Filling
Remove the croissants from the oven, and spoon generous portions of your creamy scrambled eggs and sautéed mushrooms into each one. Close the croissants gently to keep all those savory fillings snug inside.
Step 7: Serve Warm
Arrange your Savory Breakfast Croissants on a platter and serve warm to your family or guests. The buttery exterior meets the rich, flavorful interior, making for a delightful breakfast that exceeds any fast food option!

Make Ahead Options
These Savory Breakfast Croissants are perfect for busy mornings! You can prepare the filling, including scrambled eggs and sautéed mushrooms, up to 24 hours in advance. Simply whisk the eggs, sauté the mushrooms with garlic, and store both in separate airtight containers in the fridge. To maintain quality and ensure the croissants remain flaky, avoid fully assembling them until you’re ready to serve. When it’s time to enjoy, slice open the croissants, place your cheese inside, fill with the prepped eggs and mushrooms, and bake at 180°C (350°F) for about 5 minutes until warm and melty. This way, you’ll have a delicious, homemade breakfast with minimal effort!

Breakfast Croissants Recipe FAQs
How do I choose the right mushrooms for my breakfast croissants?
Absolutely! When selecting mushrooms, look for fresh and firm varieties without any dark spots or blemishes. Some great options for this recipe include cremini or button mushrooms, as they have a mild flavor that complements the eggs beautifully. If you want to add a hint of earthiness, shiitake mushrooms work well too!
How should I store leftover breakfast croissants?
Very! For optimal freshness, store leftover croissants in an airtight container at room temperature for up to 2 days. If you want to extend their life, you can refrigerate them for up to 3 days. Just remember to wrap them in parchment paper first to keep them from getting soggy.
Can I freeze my breakfast croissants? If so, how?
Of course, you can! To freeze assembled but unbaked breakfast croissants, place them on a baking sheet lined with parchment paper, ensuring they don’t touch. Put them in the freezer until frozen solid (about 1-2 hours), then transfer them to a freezer-safe bag or container. They can last up to 3 months! When you’re ready to bake, just pop them in the oven from frozen, adding a few extra minutes to the cooking time.
What should I do if my scrambled eggs turn out rubbery?
Ah, good question! This can happen if the eggs are cooked too quickly. For perfectly creamy scrambled eggs, remember to cook them low and slow. Use low heat and stir gently for about 10-15 minutes until they are creamy and slightly runny. Add a touch of butter at the end for richness, and don’t rush the process—great results take a little time!
Can I make breakfast croissants for a crowd?
Absolutely! This recipe can easily be scaled for a larger group. Just multiply the ingredients accordingly, and you can prep a tray of croissants in advance. Keep them in the fridge until ready to bake, so when your guests arrive, you’ll have a warm, delicious meal ready to serve!
Are there any allergens I should be aware of?
Definitely! The main allergens in this recipe are eggs and dairy (cheese and butter). If you have guests with dietary restrictions, consider using egg substitutes or dairy-free cheese as alternatives. Additionally, be cautious if swapping ingredients like mushrooms for meats, as they can introduce different allergens. Always check labels to ensure they meet your guests’ dietary needs.
