Spinach pesto egg sandwich is what happens when you want something more than a basic breakfast sandwich but don’t want to spend an hour in the kitchen. Creamy scrambled eggs, melty Havarti, juicy tomatoes, and a bright homemade spinach pesto all come together inside a toasted ciabatta roll. And it’s ready in under 20 minutes.

Pesto is one of those things I always want to have on hand, and I love swapping the basil for spinach when I want something a little different. My crispy pesto and goat cheese egg wrap got me hooked on pesto for breakfast, and this sandwich took it in a whole new direction. The homemade spinach pesto comes together in minutes in a blender and honestly makes the whole sandwich.

Ingredient Notes and Substitutions

Ciabatta Rolls: Ciabatta gives you that crispy exterior with a soft, chewy interior that holds up to all the fillings. You can swap for a brioche bun, sourdough bread, or an English muffin in a pinch.

Eggs: You’ll need 2 eggs per sandwich. Whisk them with a splash of milk for the fluffiest scrambled eggs. You can also use egg whites if preferred.

Milk: Just a small amount whisked into the eggs helps create a softer, fluffier texture. Any percentage of milk works, or you can use a plant-based milk.

Havarti Cheese: Havarti melts beautifully and has a mild, creamy flavor that works really well with the pesto. Provolone or gouda are great swaps.

Tomatoes: Use your favorite variety. Beefsteak, heirloom, or roma all work well here. Be sure to slice them just before assembling so they stay fresh. And add a sprinkle of salt right after slicing to enhance their flavor.

Spinach Pesto: The homemade pesto is made with fresh spinach leaves, toasted pine nuts, lemon juice, garlic, olive oil, Parmesan, salt, and pepper. If you need to save time, a store-bought basil pesto works too, though the spinach version has a fresher, lighter flavor.

How to Make a Spinach Pesto Egg Sandwich: Step-by-Step Instructions

Make the spinach pesto by adding all the pesto ingredients to a food processor or blender. Blend until smooth. Taste and adjust salt and pepper as needed. If the pesto is too thick, add one more tablespoon of olive oil and blend again.
Whisk the eggs and milk together in a bowl. Add the butter to a skillet over medium heat. Pour in the eggs and cook, stirring frequently, until the eggs are just set and no longer runny. Remove from heat and set aside.
Drizzle a little olive oil or avocado oil over the cut sides of the ciabatta rolls. Place in the air fryer at 400 degrees for 3-4 minutes.
Spread a generous layer of spinach pesto onto both halves of each toasted roll. Divide the scrambled eggs evenly over the bottom halves and top with shredded Havarti cheese. Place back in the air fryer at 400 degrees for 1-2 minutes, just until the cheese has melted.
Top with sliced tomatoes, close the sandwiches, and enjoy right away.

No air fryer? No problem. You can toast the ciabatta rolls in the oven instead. Place them cut side up on a baking sheet and broil for 2-3 minutes until golden. After adding the eggs and cheese, pop them back under the broiler for 1-2 minutes until the cheese melts. Keep a close eye on them so they don’t burn.

Sara’s Tip

Make the spinach pesto ahead of time! It stores well in the fridge for up to 3 days, which means you can have a flavor-packed breakfast sandwich ready in minutes on a busy morning. Just give it a quick stir before using. A little extra drizzle of olive oil on top before storing helps keep the color bright.

Recipe FAQs

Can I make the spinach pesto ahead of time?

Yes! The pesto stores well in an airtight container in the fridge for up to 3 days. A thin layer of olive oil on top helps preserve the color. You can also freeze pesto in ice cube trays for up to 2 months and thaw what you need.

What can I substitute for pine nuts?

Toasted walnuts, almonds, or sunflower seeds all work well in the spinach pesto. Pine nuts have the most classic flavor, but the other options are just as good and often easier to find.

Can I make this dairy-free?

Yes. Swap the Havarti for a dairy-free cheese and use nutritional yeast in place of the Parmesan in the pesto. Use plant-based milk and oil in place of butter for cooking the eggs.

Can I use a different type of bread?

Absolutely. A brioche bun, sourdough, English muffin, or even a croissant all work well. The ciabatta gives you a nice crisp texture, but any sturdy roll or bread will hold up to the fillings. I have made this recipe with sourdough bread many times as well and it turns out amazing.

How do I keep the eggs from getting rubbery?

Low and slow is the way to go with scrambled eggs. Keep the heat at medium and stir frequently. Pull the eggs off the heat just before they look fully done – they’ll finish cooking from the residual heat.

Can I add protein like bacon or sausage?

Yes! Crispy bacon or a sausage patty would layer in really well alongside the scrambled eggs.

Storage

This sandwich is best enjoyed right after assembling. The eggs and toasted bread are both at their best fresh. If you have leftover spinach pesto, store it in an airtight container in the fridge for up to 3 days. Press a piece of plastic wrap directly onto the surface or add a thin layer of olive oil to keep it from browning.
