These Dirty Fries are sublime, and the perfect addition to any slimming friendly, Weight Watchers or low calorie meal that the whole family will love!

Last year we came up with a Dirty Rice, and it’s fair to say that it was one of our most popular recipes EVER. These Dirty Fries will be another favourite as they’re sooooooooo good!!

Bacon, potatoes and Cajun spice may sound like a bit of an odd mix, but it’s truly amazing. It has to be one of our favourite combinations ever.

Dirty Rice and Dirty Fries get their names from the appearance of the finished dish. They’re usually finished with chicken livers, which give them a brown appearance (although we’ve obviously left them out!)

We like to cook these Dirty Fries in an Actifry. You can buy this Tefal Actifry Express XL on Amazon!

If you use a lot of Cajun spice mix, you can buy it in bulk on Amazon, which can work out a little cheaper than the small jars!

There are 514 calories in each portion of our slimming friendly dirty fries. This means it falls into our Special Occasion recipe category.

Actifry method
  1. Cut the potatoes into chips. You don't have to peel them but make sure you wash them. Toss them in a decent amount of low calorie cooking spray, 1 tsp of the Cajun spice mix, and then season them well.
  2. Cook for 30 minutes in the Actifry, then set them aside.
  3. Add the onions, peppers, bacon, remaining Cajun seasoning and Worcestershire sauce to the air fryer. Spray with some low calorie cooking spray and cook for 10 minutes.
  4. Return the chips and cook for 1 minute, then remove the paddle and sprinkle the cheese over the top of the chips.
  5. Cook for 1 minute and serve.
Oven method
  1. Pre heat the oven to 200°C. Then cut the potatoes into chips. There's no need to peel them.
  2. Place them in a pan of boiling salted water and simmer until they start to soften but are still quite firm.
  3. Drain the potatoes and spray a baking tray with low calorie cooking spray. Coat the potatoes in low calorie cooking spray and sprinkle them with a little salt and half of the Cajun seasoning.
  4. Place in the oven for 20-30 minutes until they are soft and starting to colour.
  5. Meanwhile, spray a frying pan with a generous amount of low calorie cooking spray, then add the chopped peppers, bacon, onions, Worcestershire sauce and remaining Cajun seasoning.
  6. Cook for a few minutes until they start to soften. When the chips are cooked and browned, add them to the frying pan and stir well.
  7. Place the contents into an oven proof dish and cook in the oven for 5-10 minutes, or until the cheese has melted. Then serve.

What degree do I choose to cook my chips in my Actifry?


    HollyThursday 17th September 2020

    Hi Megan, in an Airfryer I would suggest to cook the Dirty Fries at 160ºC in an Actifry set the timer for 30 minutes and follow the rest of the steps in the recipe. Hope that helps!


Laura HonourSunday 24th May 2020

Lovely recipe – but is there a good way to cook the “chips” without an Actifry, as I don’t have one, thanks 🙂

    Hi Laura. If you scroll down the page there is a recipe card at the end of the page which gives detailed instructions for an oven method as well as an Actifry method.
