Full Ingredients

For the Pesto Egg & Mozzarella Bagel

• 1 plain bagel, split horizontally
• 1 large egg
• 2 tbsp basil pesto, divided (store-bought or homemade)
• 2 oz fresh mozzarella, cut into 4–5 slices about 0.5 cm (1/4 inch) thick
• 1 tsp unsalted butter or olive oil (for cooking the egg)
• 1 pinch kosher salt (about 1/16 tsp), or to taste
• 1/8 tsp freshly ground black pepper, plus more for serving

Optional Garnishes & Add-Ins

• 2–3 fresh basil leaves, torn or thinly sliced
• Pinch crushed red pepper flakes
• 2–3 thin slices ripe tomato or roasted red pepper strips
• Small drizzle (about 1 tsp) extra-virgin olive oil on top just before serving

Step-by-Step Instructions

Step 1: Gather and prep your ingredients

Set out your bagel, egg, pesto, fresh mozzarella, butter or oil, salt, and pepper. If you are using optional garnishes like basil leaves or tomato slices, rinse and dry them now. Slice the fresh mozzarella into even rounds about 0.5 cm (1/4 inch) thick so they melt slightly but still keep their shape. Having everything ready before you start cooking the egg will help you assemble the sandwich while everything is hot.

Step 2: Toast the bagel

Split the bagel horizontally. Toast both halves in a toaster or under a broiler until lightly golden and crisp on the cut sides, 2–4 minutes depending on your equipment. You want a bit of crunch on the outside while the inside stays tender. Once toasted, set the bagel halves on a plate, cut side up. If you like, you can very lightly butter the cut sides, but it is not required since the pesto is rich.

Step 3: Fry the egg

Place a small nonstick skillet over medium heat. Add the butter or olive oil and let it melt and coat the pan. Crack the egg into the pan, keeping the yolk intact if you want it runny. Sprinkle the egg with a pinch of kosher salt and the 1/8 tsp of freshly ground black pepper. Cook for 3–4 minutes, or until the whites are fully set and the yolk is cooked to your liking. Reduce the heat slightly if the edges brown too quickly.

In the final 30–45 seconds of cooking, spoon 1 tablespoon of pesto directly over the top surface of the egg, spreading it gently with the back of the spoon. Let it warm through so the pesto becomes glossy and aromatic but does not burn.

Step 4: Spread pesto and layer the mozzarella

While the egg finishes cooking, spread the remaining 1 tablespoon of pesto over the cut sides of the warm toasted bagel. Divide it evenly between the top and bottom halves so every bite has good flavor. Place the mozzarella slices on the bottom half of the bagel in an even layer. The residual heat from the bagel will start to soften the cheese. If you prefer it slightly meltier, you can briefly place the mozzarella-topped bagel half under a broiler for 30–60 seconds, watching carefully so it does not burn.

Step 5: Add the pesto egg and finish with seasoning

Using a spatula, carefully lift the pesto-covered fried egg from the skillet and place it directly on top of the mozzarella layer. The warm egg will gently soften the cheese further. If using, tuck in tomato slices or roasted red pepper strips around the egg. Sprinkle a little extra freshly cracked black pepper over the top, plus crushed red pepper flakes if you like a bit of heat. Add torn basil leaves and a tiny drizzle of extra-virgin olive oil for extra freshness and shine.

Step 6: Assemble and serve

Place the top half of the bagel over the egg to close the sandwich, pressing very gently so everything stays stacked but the yolk does not burst unless you want that effect. Serve immediately while the bagel is warm, the egg is hot, and the mozzarella is soft and creamy. This sandwich is best enjoyed right away, with a napkin handy in case of a deliciously runny yolk and pesto drips.

Pro Tips

• For a classic runny yolk, cook the egg on medium heat for about 3 minutes, just until the whites are set and the edges crisp slightly.
• Use good-quality basil pesto; its flavor drives the whole sandwich. If it is very thick, stir in 1–2 tsp olive oil to loosen it before using.
• Fresh mozzarella is best, but if you only have low-moisture mozzarella, shred it so it melts faster on the warm bagel.
• Lightly toasting the bagel keeps it from going soggy under the pesto and egg while still giving you a tender interior.
• If making more than one sandwich, keep finished eggs warm on a plate tented with foil and assemble just before serving.

Variations

• Greens-loaded: Add a handful of baby spinach or arugula on top of the mozzarella before adding the egg for extra freshness and color.
• Caprese twist: Layer fresh tomato slices and a tiny drizzle of balsamic glaze with the mozzarella to echo classic caprese flavors.
• Spicy version: Stir a pinch of crushed red pepper flakes or a few drops of hot sauce into the pesto before spooning it over the egg.

Storage & Make-Ahead

This Pesto Egg & Mozzarella Bagel is best made and eaten fresh; the textures of the toasted bagel, runny egg, and soft mozzarella are at their peak right after cooking. If you need to work ahead, you can prep components: slice the mozzarella and store it in an airtight container in the refrigerator for up to 3 days, and have your pesto ready to go. Bagels can be sliced and frozen in a zip-top bag for up to 3 months; toast directly from frozen. Avoid fully assembling the sandwich in advance, as the bagel will become soggy and the egg will overcook when reheated. If you must reheat a fully assembled sandwich, warm it gently in a 160°C (325°F) oven for 8–10 minutes, understanding the yolk will be fully set and the texture less delicate.
