Cajun Chicken Burger

Do you have recipes that you’ve made forever, but have never given a thought about the recipe, the exact how to’s, because you’ve always made it this way? This cajun chicken burger is one of them for me. A juicy, grilled spiced (but not too spicy) chicken thigh on a brioche bun topped with all the goodies… smashed avocado, cheese, sour cream, and chili sauce. Sounds good, doesn’t it? Yep, this is about to become your favorite Friday night (or any night!) homemade takeaway-style meal.

Here’s why you need these cajun chicken burgers in your life

They are an easy way to feed a crowd for those Summer backyard BBQs. The chicken can be marinated in advance, buns buttered and salad prepped. Yes, there’s the avocado that needs to be made last minute, but other than that there isn’t much left to do but pop everything in the middle of the table and let everyone help themselves.

As well as making the tastiest chicken burger around, leftover cajun chicken makes the BEST toasties. So I ALWAYS make a little extra! Sliced cajun chicken, vintage cheddar cheese, finely sliced spring onions with siracha mayonnaise between two slices of bread, buttered on the outside, then toasted. Ahhhh!

What you need to get started

  • Skinless chicken thighs approx. 500g in total, trimmed of any fat. You can also use chicken breast meat for this recipe. To substitute, you will need 2 chicken breasts, each cut horizontally, giving 4 chicken pieces of even thickness.


  • Cajun seasoning. An essential in my spice drawer. I use it to make cajun chicken tacos, grilled salmon, and prawns and its delicious sprinkled over baked potatoes.


  • Olive oil and Butter


  • Brioche buns or hamburger buns


  • Vegetables – English spinach, a ripe avocado


  • Vintage cheddar cheese


  • Sea salt flakes and freshly ground black pepper


  • Sour cream. I also substitute with mayonnaise if I don’t have any sour cream in the fridge. Both work equally as well.

  • Sweet chili sauce

The details

  1. Prepare your burger buns by cutting each one in half and buttering each interior side.


  2. Trim the chicken thighs of any bone and fat. In a medium bowl, combine the chicken thighs, cajun spice mix, and 1 tsp sea salt flakes. Toss to coat the chicken.


  3. Heat a grill pan on medium heat. Once hot, add the oil and then the chicken. Cook for 5 minutes then turn over to cook the other side. Once you have turned the chicken, lay a piece of cheddar cheese on top of each chicken piece to melt. Cook another 5 minutes. Check that your chicken is fully cooked (if not, cook for an extra few minutes) remove it from the pan, and pop the chicken aside to rest.


  4. While the chicken is cooking make the smashed avocado by mashing the avocado in a small bowl and seasoning it with a little sea salt and freshly ground pepper.


  5. Place each burger bun buttered side down on the grill pan and gently cook for 1 minute on each side.


  6. To assemble the burger… Place a bed of English spinach on the bottom piece of each burger bun. Top with the grilled chicken and cheese. Add the smashed avocado, then the sour cream and sweet chili sauce. Place the burger bun lid on top and you have your Cajun chicken burger!

Equipment you’ll need to cook this grilled cajun chicken burger recipe

A large bowl and a good pair of tongs are essential.

There is quite a few ways to cook cajun chicken burgers. Personally, I use my 26cm Le Creuset cast iron grill pan. I’ve had it for years and it’s my go-to pan when I’m grilling inside. You can also use a bbq grill or a large frying pan.

How do I know if my chicken is cooked?

The easiest way is with a digital instant read thermometer, however, most of the time if I think that there is a chance it is undercooked, I will just cut into the thickest part of the meat to ensure it is cooked through. It’s a bit different if you are cooking commercially, however, I’m cooking for family and friends so I think it’s a totally acceptable way to check a chicken thigh.

When using a thermometer, the cooked temperature of a chicken thigh is 75C.

Let’s talk sides, shall we?

Regular fries or potato wedges are the obvious choices, but what about oven-baked sweet potato fries alongside our crispy cajun chicken burger? Personally, I prefer them! Another favorite of mine is alongside the BEST potato salad you’ll ever eat. It’s always a winner together.

Variations

You can totally substitute the sour cream for mayonnaise. I make it both ways depending on what’s in the fridge.

Want to tone down the spiciness? Try this… Nix the sour cream and chili sauce. Instead of mashing the avocado, slice it instead and add a scoop of homemade creamy slaw. Plus if you are having a bbq, it’s one less salad to make!

The Irishman likes to add a rasher of bacon and sliced tomato to his cajun chicken burger.
