Croissant Breakfast Sandwich with Spinach

As an Amazon affiliate, I earn from qualifying purchases.

For this vegetarian croissant breakfast sandwich, croissants are filled with scrambled eggs mixed with creamy spinach and sundried tomatoes, then baked to crispy perfection.

I love a good breakfast sandwich, and having lived in France, my favorite delivery device is obviously a croissant. Bagels and English muffins have their appeal of course, but there’s something about the crispy, buttery layers of a croissant that are next level breakfast sandwich-ing.

Why Make This Recipe

• Great On-the-Go Breakfast: You can wrap one of these up, and eat it wherever you like. Imagine how happy you'd be to unwrap one of these at your desk!
• Vegetarian Option: This sandwich is completely vegetarian but still packed with great flavors. Perfect if you are working on reducing your meat consumption!
• Great for Groups: You can make several of these at once, which makes them perfect to serve for a bunch of hungry family members, or wrap some up to reheat later.

🥗 Ingredients

• Eggs: Feel free to replace with egg-whites, or with a combination of egg whites and whole eggs. 
• Baby spinach: Baby arugula would work here as well. Or even some finely shredded kale or swiss chard.
• Sun-dried tomatoes: You can leave these out if you prefer, or you can replace with quartered fresh cherry tomatoes 
• Cream cheese: I love the luxuriousness that cream cheese adds to the spinach mixture, but you could leave it out if you like. You could also replace with a little bit of feta. Or, you could cook down a bit of heavy cream in a small saucepan until it thickens, and add that to your spinach mixture.

🥣 Step-by-Step Instructions

First, preheat your oven to 350 degrees Fahrenheit or 175 Celsius. Then whisk 8 eggs together until whites and yolks are completely combined. Season with ¼ t. salt and ¼ t. pepper.

Slice croissants in half horizontally. Heat 2 teaspoons of olive oil in a medium-sized nonstick saucepan over medium-high heat. Add 4 ounces of baby spinach and 2 tablespoons of chopped sun-dried tomatoes, and cook until spinach wilts, 3-5 minutes. Drain out any liquid by pressing the mixture against one side of the pan, and letting the excess liquid pool into the other side where you can scoop it out with a spoon.

Now stir in 2 tablespoons of cream cheese and cook until completely melted, about 2 minutes.

Remove spinach mixture to a bowl. Wipe out pan and add 1 tablespoon of butter. Melt over medium-low heat. Add eggs and cook slowly, using a rubber spatula to scrape along the bottom of the pan and around the sides frequently. The lower the heat, the longer this takes, but the creamier your finished eggs will be.

When eggs are just scrambled to your liking, stir in the spinach mixture. Now, lay out the bottoms of your croissants on a 9x13-inch baking dish, and divide the egg-spinach mixture between them. Sprinkle each with feta, then put on the tops of the croissants.

Bake for 10-15 minutes, until cheese starts to melt and croissants are crispy and lightly toasted on top.

👩‍🍳 Expert Tips

This is a very flexible recipe, and you can get creative with the filling. For a non-vegetarian version, you could add cooked bacon or chopped ham to your scrambled eggs, along with some cheddar cheese. Or try combining your eggs with sautéed mushrooms and onions, and gruyère cheese. Really, however you like your scrambled eggs or omelettes works here—there are tons of possibilities.

Now that croissants are on your mind, are you mentally going through all the other ways you can eat a croissant? Me too. Of course, croissants can just be eaten plain, or spread with jam. If you’re my youngest daughter, you’ll open one up and slather it with butter (as if there wasn’t enough in there already).

And croissant sandwiches go beyond breakfast as well. Try chicken salad tucked in a croissant or croissants stuffed with shrimp salad (mini ones for a fancy party lunch spread are adorable). You can also take them in a sweet direction and serve with chocolate, nutella, pastry cream, nuts, and/or fresh fruit and berries. Stale croissants (day-old) are perfect for using in a breakfast casserole or bread pudding.

Notes

Make-Ahead Instructions: Make the filling first. Then you can fill the croissants and wrap in foil to bake later. Or you can put the filling in an airtight container, and then later slice your croissants, fill, and bake. Keep the filled croissants or the packaged-up filling in the refrigerator until you're ready. The sandwiches or filling will keep up to 8 hours in the refrigerator. Also, after you have baked your sandwiches, you can wrap up leftovers and put them in the refrigerator for another 1-2 days. Reheating in the oven will give you the best chance of regaining the crispiness from the first bake.

Ingredient Tips: Day-old croissants will work just fine for this dish, and in fact may be easier to slice than fresh croissants. For the filling ingredients, you can get creative and change them up as you like—add bacon if you're a meat-lover, or try different vegetables like mushrooms or onions.
