Introduction

The schnitzel sandwich is a delicious, crispy chicken treat perfect for a satisfying lunch or casual dinner. With a crunchy coating and a spicy mayo kick, this sandwich combines simple ingredients into a flavorful meal that’s easy to prepare at home.

A thick sandwich sits on a wooden board lined with white parchment paper, showing five layers within two slices of crusty, brown bread with a soft, light interior. The bottom layer has a spread of orange sauce, topped by fresh green lettuce, then thin cucumber slices. Above that is a large, golden-brown crispy breaded cutlet, followed by orange sauce and thin shavings of pale cheese. The sandwich is surrounded by scattered cheese shavings and a chunk of hard cheese on a wooden board in the background, all set against a white marbled textured surface.

Ingredients

1 large chicken breast
3 tbsp plain flour, seasoned well

1 egg, beaten
5 tbsp finely grated parmesan

75g dried breadcrumbs
Groundnut or sunflower oil, for frying

3 heaped tbsp mayonnaise
1 tbsp sriracha or other chilli sauce
4 thick slices of crusty bread (such as bloomer)

1 Little Gem lettuce, shredded
¼ cucumber, thinly sliced

Instructions

Step 1: Lay the chicken breast flat on a board and carefully slice through the middle to create two equal-sized, thinner fillets. Cover with baking parchment and gently bash with a rolling pin until about ½ cm thick.

Step 2: Place the seasoned flour in a shallow dish, the beaten egg in a second dish, and mix the parmesan with the breadcrumbs in a third dish. Dip each chicken fillet first in the flour, shaking off excess, then in the egg, and finally coat evenly with the breadcrumb and parmesan mixture.
Step 3: Heat enough oil to cover about ½ cm of the pan over medium heat. Fry the schnitzels for 4-5 minutes on one side until crisp and golden, then carefully flip and cook for another 4 minutes until fully cooked. Drain on kitchen paper.
Step 4: Mix the mayonnaise with the sriracha in a small bowl. Spread this spicy mayo over two slices of the crusty bread.

Step 5: Assemble the sandwich by layering shredded lettuce on the bread with mayo, then add the cooked chicken schnitzel and cucumber slices. Top with the remaining bread slices and serve immediately.

Tips & Variations

For extra flavor, marinate the chicken briefly in buttermilk or lemon juice before coating.
Try swapping sriracha for a smoky chipotle sauce for a different spicy twist.

Use gluten-free flour and breadcrumbs to make this sandwich gluten-free.
Add sliced tomatoes or pickles for extra freshness and crunch.

Storage

It’s best to enjoy this sandwich fresh to keep the schnitzel crispy. If you have leftovers, store the chicken schnitzel separate in an airtight container in the fridge for up to 2 days. Reheat gently in a skillet or oven to preserve the crunch before assembling a new sandwich.
