Smashed Avocado and Bacon Club Sandwich

A club sandwich is all about height, crunch and clearly defined layers: toasted bread, crisp leaves, tomato, savoury meat and a creamy spread, stacked so every bite has structure. This version keeps that familiar American lunch-counter feel but adds smashed avocado for a richer, fresher layer alongside crispy bacon and sliced chicken breast. Romaine and firm ripe tomato stop it feeling heavy, while the mayonnaise and Dijon bring the classic tangy finish. Best served as soon as it is assembled, cut into quarters for the traditional club sandwich shape.

Why this recipe works

  • Classic texture contrast: Crisp toast, bacon and romaine balance the soft avocado, sliced chicken and juicy tomato.
  • Freshness cuts through richness: Lemon in the avocado and Dijon in the mayonnaise sharpen the creamy and salty layers.
  • Built for a fast lunch: The bacon and chicken cook in the same pan while the bread toasts and the fillings are prepared.

Timing notes

  • Serve soon after building: The sandwich is at its best straight away, before the toast softens and the avocado begins to darken.
  • Rest the chicken briefly: A short rest before slicing helps the chicken stay juicier and makes the layers neater.

Ingredient notes

  • Choose a ripe avocado: Use an avocado that yields gently to pressure so it mashes smoothly but still keeps a little texture.
  • Use a firm tomato: A ripe but firm tomato gives freshness without releasing too much liquid into the toast.

Texture tips

  • Protect the toast: Keep the lettuce and bacon close to the wetter ingredients to help stop the bread from becoming soft too quickly.
  • Leave some avocado texture: Mash the avocado lightly rather than completely smooth for a more satisfying bite.

Common mistakes

  • Avoid dry chicken: Cook the chicken only until fully cooked through, then rest it briefly before slicing.
  • Do not build too far ahead: Assembled club sandwiches lose their crisp structure quickly, especially once avocado and tomato are in place.

  1. Cook the bacon in a frying pan over medium heat for 6 to 8 minutes, turning, until deep golden and crisp. Lift onto a plate and leave the fat in the pan.
  2. Season the chicken with a pinch of the fine sea salt and black pepper. Cook in the same pan over medium heat for 4 to 6 minutes per side, until cooked through and the juices run clear, then rest for 2 minutes before slicing.
  3. Toast the white bread until golden. Meanwhile, halve the avocado and scoop the flesh into a bowl; squeeze over the lemon and mash with a fork, then season with the remaining fine sea salt and black pepper.
  4. Thinly slice the tomato. Mix the mayonnaise and dijon mustard in a small bowl.
  5. Spread the smashed avocado over one slice of toast. Top with the romaine lettuce, sliced chicken, bacon and tomato, then spread the mayonnaise mixture over a second slice of toast and place it on top.
  6. Add the final slice of toast on top and press gently to set the layers. Slice into quarters and serve straight away.

Recipe notes

Tips

  • For neater layers, let the chicken cool for 2 minutes before slicing so the juices settle.
  • If the avocado is very ripe, mash it with a fork but leave a few small chunks for better texture.
  • If serving to anyone vulnerable, make sure the chicken is fully cooked through and piping hot before resting and slicing.

Substitutions

  • Replace Dijon mustard with whole-grain mustard for a milder, more textured spread.
  • Replace white bread with whole-grain bread for a heartier club.

Storage

  • Refrigerate up to 1 days
  • Best eaten straight away. If needed, wrap and refrigerate for up to 1 day; the bread will soften and the avocado may darken. Eat cold, or re-toast the bread separately and rebuild if you want a crisper result.
