How many calories are there in a homemade burger and fries?

Answer 1

It depends on the size of the portion. There are on average 300 calories in a normal/small (restaurant breakfast) size serving of plain home fries.
Loads I'm afraid. The kind of serving you'd get in a cafe would be about 300.

Answer 2

It depends how you make it!

Leaner meat has less fat, so less calories. So if you use good quality, lean, mince, that will lower the calories.

If you add egg, or bread, or bacon to the mix, that might increase the calorie content.

Then how you cook it makes a big difference - frying means high-calorie, grilling, low-calorie.

The fries also depend how you made them. Thicker chips (fries) will absorb less fat overall, due to having less surface area to volume, so they will have less calories. But if you make home-made oven chips, then they are baked, so that is also lower calorie.

So there isn't an answer to your question - because it depends on so many factors.
