The Ultimate Turkey Avocado Club Sandwich
Toasted sourdough, herb mayo, crispy bacon, ripe avocado, and sliced turkey piled high — the lunch sandwich that ruins all other sandwiches.

A truly great club sandwich is more than the sum of its parts — it is an architectural achievement. Every layer needs to earn its place. The bread has to be sturdy enough to hold everything together but tender enough to bite through cleanly. The bacon must be crisp but not shattering. The avocado must be ripe enough to mash slightly but not so soft it slides everywhere. This is my answer to all of that: a tall, generous, herb-mayo-slathered tower of a sandwich that is genuinely worth turning on the oven for.
I have a thing about sandwiches. I think they are wildly underestimated — treated like a quick lunch to inhale at your desk instead of the artful, balanced meals they can actually be. A great sandwich is the kind of food that proves how much simple ingredients matter. There is no fancy technique, no rare equipment, no clever shortcut to hide behind. You just have bread and what you put on it, and every choice shows.
This particular club came out of years of obsessively ordering and judging club sandwiches at every diner, deli, and hotel restaurant I have ever set foot in. I had opinions. Strong ones. I do not like clubs with three slices of bread because the middle slice is always dry and ruins the structural integrity. I do not like clubs with iceberg lettuce because it shatters at the first bite and sends everything flying. I do not like clubs where the bacon is undercooked, because rubbery bacon in a cold sandwich is genuinely an insult.
So I built my own version, one I make at least once a week for lunch and have absolutely zero shame about. It starts with two thick slices of good sourdough toasted in the cast-iron skillet with a tiny bit of butter until each side is dark golden brown — almost croutonesque on the edges but still pillowy inside. Then comes the herb mayo, which is just good mayonnaise stirred together with finely chopped chives, parsley, fresh dill, a tiny squeeze of lemon, and a grind of black pepper. It tastes like a green garden and binds the whole sandwich together with a layer of flavor that everything else builds on.
The bacon has to be cooked low and slow in the oven on a wire rack until it is crispy through but still slightly bendy in the middle — never shattering. The avocado gets smashed gently right onto the bread with a fork so it spreads but does not disappear. Then a generous pile of high-quality sliced turkey, a layer of butter lettuce (tender, not crunchy), thick slices of vine-ripened tomato sprinkled with flaky salt, and another swipe of herb mayo on the top slice. I close it firmly, press down with my palm for about ten seconds to lock everything together, and slice it diagonally with my sharpest knife. That diagonal cut is important. Do not skip it.
I like to serve it with crispy salt-and-vinegar chips and a pickle on the side. My husband adds a runny fried egg sometimes. My son demolishes one and then asks for another. It is, simply put, the best sandwich I know how to make.

How to make it
- 1
Preheat the oven to 400°F. Arrange the bacon on a wire rack set over a foil-lined sheet pan.
- 2
Bake the bacon for 18-22 minutes, until deeply golden but still slightly bendy. Drain on paper towels.
- 3
While the bacon cooks, whisk together the mayonnaise, chives, parsley, dill, lemon juice, a pinch of salt, and several grinds of black pepper in a small bowl.
- 4
Spread the softened butter lightly on both sides of each slice of sourdough.
- 5
Heat a large cast-iron skillet over medium heat. Toast the bread, 2 slices at a time, until deeply golden on both sides, about 2 minutes per side.
- 6
Slice the avocado in half, remove the pit, and scoop the flesh into a bowl. Mash with a fork until chunky-smooth and season with a pinch of salt.
- 7
Spread herb mayo generously on the inside of all four toasted slices.
- 8
On two slices, smash the avocado in an even layer.
- 9
Top the avocado with sliced turkey, dividing evenly. Add a butter lettuce leaf or two.
- 10
Layer the tomato slices on top of the lettuce and season with flaky salt.
- 11
Add three crispy bacon strips per sandwich, slightly overlapping.
- 12
Close the sandwiches with the remaining bread, mayo side down. Press firmly with your palm for 10 seconds to compact.
- 13
Use a sharp serrated knife to slice each sandwich diagonally. Serve immediately with chips and pickles.
Tips from the kitchen
- 01
Use day-old sourdough — it toasts up crispier than fresh.
- 02
Cooking bacon on a rack in the oven keeps it flat and lets the fat drain away. No more curled, greasy strips.
- 03
Press, do not crush. Ten seconds with your palm locks the layers together without squishing the avocado.
- 04
Toast the bread cut-side facing the same way you will assemble — the darker, crispier side should face the fillings.
- 05
Use a serrated knife and a sawing motion, not a downward chop, when cutting. Otherwise everything collapses.
- 06
Make the herb mayo a day ahead — the flavors deepen and it spreads even better when chilled overnight.
Frequently asked
Can I make this ahead of time?
Not the whole sandwich, but everything can be prepped: cook the bacon, make the herb mayo, slice the turkey and tomato. Assemble right before eating.
What's the best bread?
A bakery-style sourdough with a crackly crust and chewy crumb is ideal. Brioche, ciabatta, or a sturdy whole-grain loaf also work.
Can I use rotisserie chicken instead?
Absolutely — pulled rotisserie chicken makes a fantastic substitute. Just shred it and season lightly.
How do I keep avocado from browning?
Mash with lemon juice and assemble right before serving. Avocado does not store well once exposed to air.
Is there a vegetarian version?
Yes — skip the bacon, use double avocado, add roasted red peppers and a few slices of smoked gouda for a meaty, satisfying bite.
