Cajun Spiced Chicken Burger with Homemade Cajun Marinade

Diet? What diet? Honestly, can you think of any other ‘diet’ that allows you to eat a double stacked burger dripping with cheese, because I can’t! This Syn Free Cajun Spiced Chicken Burger is to die for, especially as it’s made with a homemade Cajun marinade!

You don’t strictly have to double stack this burger, but lets be honest why wouldn’t you! Supermarket chicken breasts are usually kind of small (I’m waiting on my next Muscle Foods order for my giant ones to arrive!) and if you’re a hungry person like me then double stacking is really par for the course. More importantly, on Slimming World, double stacking this Cajun spiced chicken burger doesn’t put you in danger of overeating because you’re still using your Healthy Extra B bun and Healthy Extra A cheese, both of which are measured.

Making The Cajun Spiced Chicken Burger Marinade

You can’t have a Cajun spiced burger without Cajun seasoning! I use the Schwartz seasoning in pretty much every Cajun dish that I make (see my Creamy Cajun Chicken Pasta here) and I could have easily just rubbed the burger in some seasoning and left it at that. However, that can lead to dry meat (especially as we’re not cooking it in oil) and I don’t feel like you really get a sense of that classic Cajun flavour and way of cooking. Instead I made a very simple Cajun marinade for my Cajun Spiced Chicken Burger, which uses very simple ingredients that you probably have in the cupboard already!

As you can see the marinade gives the meat a really strong colour and adds a whole new texture to your meal. It also adds more speed food, as it’s made using a green pepper and onion, which can’t be a bad thing! The longer you marinade your meat for, the more the flavour will sink in, however it needs a minimum of half an hour so if you’re just whacking together a quick dinner then you don’t have to worry about a long marinade too much.

Serving Suggestions

If you’re wondering where I got the serving board in the picture above, it’s actually from Aldi! It set me back about £3.99 and is made from marble and wood and I adore it! I’m very big on presenting my food in the prettiest way possible, I think it makes eating it even more fun, and being able to acquire gorgeous serving boards on a tight budget is wonderful! Aldi is great for picking up all of the things you never knew you needed without spending too much money, and I’m sure your local one will have these boards in stock if you head down soon!  I served my Cajun Spiced Chicken Burgers with a hearty helping of homemade syn free chips (see my recipe here) and some extra veg to add my third of a plate speed. You can add whichever veg you fancy, or simply include more salad, it’s totally up to you!

    This really doesn't look like slimming food, I could happily eat something like that every day on a diet! I completely agree with you about the cajun seasoning, I use the schwartz one all the time too.

    Oooh - I haven't tried the Schwarz Cajun Seasoning - but I think I might have to after this - it is just mouthwateringly exciting!! I keep wanting to lick the screen. This is definitely not your average diet food!! And I can;t remember if I have said already or not but I am loving the new look and feel of your website - it's great - really professional!! Thanks for linking up to #CookBlogShare :-) Eb x

      Thanks Eb, I'm a big fan of the Schwartz ones, they do pack a lot of flavour into them! Thanks for your comment about the new look of my blog, I really like it! No doubt I'll keep chopping and changing forever but for now I think this works really well :) x

    Loving the look of that Cajun dressing - think I'll give that a try. I'm a big fan of Cajun seasoning but usually just mix it with olive oil to use as a rub when I'm being lazy! #CookBlogShare
