  • 1 serving leftover McDonalds fries
  • dipping sauce (optional)


  • Put the fries in a single layer on the air fryer tray or air fryer basket. It's OK if some fries are overlapping.
  • Air fry for 3 minutes at 400°F (200°C). Use the top rack position for air fryer ovens.
  • Let the fries cool for 1-2 minutes before eating (they'll continue to crisp up). Serve with your favorite dipping sauce.


This is a level 3 recipe (weight maintenance and active lifestyles).It’s true that McDonald’s fries count towards your intake of veggies, but they’re really not an optimal choice. They’re an ultra-processed food that is high in calories for a small amount of food.
Here’s the nutritional breakdown (at the time of writing) for McDonald’s fries in the US:

McDonald’s fries are not keto, low carb, Paleo, vegan, or (perhaps surprisingly) vegetarian. If you have celiac disease, I would not count on them being gluten free. That means you need to give up McDonald’s fries with practically every special diet out there.
One of the reasons people give for eating at McDonald’s is that it is cheap. However, I paid $3.59 for a medium fries. 
I actually feel that’s kind of expensive for what you get. I could get a whole bag of frozen fries for that price.
You’ll save money and enjoy a more nutrient-rich option when you make baked homemade fries. You can make some very tasty fries that give you a lot more food for the calories. This can help you feel satisfied both if you have a weight loss goal and if you’re trying to maintain a healthy weight.
Here’s one way to make a healthy burger and fries. Though a common dietitian mantra is “all foods can fit,” that doesn’t mean you must eat all foods. 
This was the first time I’ve eaten McDonald’s fries in many years. I don't see myself having them again for a long time. They don’t appeal to me taste-wise and there's other things I’d rather have if I want a treat.
Nutrition information is for one serving of McDonald’s medium french fries. Exact nutrition information for this side dish depends on the size fries you’re having.
