It’s nearly the beginning of summer. This means officially, barbecue season started in England, all garden centres are chock-full of folks that are elevating their barbecue game. Whether looking for barbecue accesories or just the garden loungers, it’s clear that everyone loves sunny days here.

I make no apologies for firing up my grill in all seasons, but the edge of summer sends me into a barbecue frenzy. My buttermilk chicken burger is guaranteed to be a delight, after all my trusty grill is a Weber Genesis.

If you’re looking for a burger that’s packed with flavor and offers a tantalizing twist, then you’re in for a treat!

The burger buns

I am very particular about the nest of my buttermilk chicken burger, I like mine soft rather than crusty.

I mean, it’s no sin to use shop bought burger buns, especially if they are soft (like brioche type).

This weekend though calls for the next level burger buns and I have made sourdough rolls. The weather helped to quickly rise my dough, since it’s hot already here in North East of Essex, England.

I used my no-knead sourdough recipe, but divided the dough and shaped eight balls. I baked them in a square cake tin, greased with a slick of butter, although I am sure a baking sheet could also work well.

The secret in getting soft rolls was to spray a little water on the top of the buns before getting them into the oven. A little steam from a tray with water placed on the rack underneath will help keep them soft and moist.

The actual buttermilk burger

For a healthy version, I use chicken sizzlers. These are slices of chicken breast that are quicker to cook and really tender. They are often my go to protein during the week, because they take merely moments in the pan.

For the buttermilk chicken burgers, the marinade is the key. I kept it simple this time:

  • a dash of smoked paprika,
  • salt, pepper and garlic
  • swirled with the buttermilk and a slosh of olive oil

Once you toss the chicken sizzlers in the marinade to coat well, it only takes a little time for the flavors to work their way in. This way the buttermilk chicken burgers stay moist and almost cook from the inside.

The creamy avocado dressing

My dressings or sauces for all things barbecue change up every now and then. Of course, you can use whatever sauces your fridge door has on offer.

I prefer creamy embellishments for chicken burgers. Hence a creamy limey avocado dressing. Avocado brings a rich and velvety texture while adding a dose of healthy fats. If you prefer leaving the mayo out, a great option is olive oil (always use extra virgin) and a little Greek yogurt or sour cream. Use full fat yogurts, your gut will thank you!

To make my avocado dressing, you’ll need:

  • ripe avocados
  • mayonnaise
  • freshly squeezed lime juice and, lime zest
  • garlic
  • a pinch of salt and pepper
  • a dash of Sriracha sauce or just a pinch of crushed chili flakes.

This vibrant green dressing adds a delightful creaminess to your burger, while the tangy lime juice perfectly balances the richness of the avocado.

The sides and toppings

There should always be chips (or fries) next to a burger, I hear you say. Well, you won’t be disappointed: my crispy oven fries are made from diced potatoes, skin and all. I use a handy vegetable chopper to get even dices. They cook faster and are easier to move in the tray.

Grill fries in a bowl

Top with your choice of colorful veggies and fresh salad, I like to mix it up so I can get even more antioxidants: radishes and cucumbers thinly sliced work well here.

Often I dice an array of colorful Mediterranean vegetables and grill alongside on a grill pan or just in tinfoil trays: once you toss your vegetables with olive oil and seasonings, throw them in the tray. They will sizzle nicely on the grill, without any mess or burnt bits.

Feel free to improvise here, any toppings will work.

Assemble the buttermilk chicken burger

When I make burgers, it sometimes feels like a great endeavor to bring all the elements together at the end. But it needn’t be.

Bring all of your elements to the table and let your family dig in. They will quickly help themselves up to a generous portion of veggies and fries, slather up their burger buns with creamy avocado dressing and nestle a juicy chicken burger in.
