Oven french fries vs fried french fries
Authentic french fries are deep-fried in oil. Since more and more people are aware of saturated fats in fried foods, home cooks are deciding to make french fries in the oven.
Both deep-fried fries and oven fries can turn out crispy, but it depends on how you prepare the potatoes. The essential thing that separates crispy and not crispy french fries is the type of the potato and cooking technique called blanching. The best potatoes for making french fries are Idaho or also called Russet potatoes. Russet potatoes are much denser than other potato types, and they are not as moist as other potato types.
Blanching is a cooking technique in which ingredients are put in boiling water or hot oil for a short time, removed from boiling water or oil, and put into a cold place or ice water.
Blanching french fries in water
When it comes to blanching french fries in water, the potatoes are put in boiling water. The cooking time is about five minutes. After the cooking process is done, it is crucial to cool them down completely before putting them in hot oil or the oven. The cooking and cooling process makes a thin outer layer on the potato, which becomes crispy after you fry it or bake it.
Blanching french fries in oil
Blanching in oil is similar to blanching in water. Cut potatoes are put in hot oil, which shouldn’t be more heated than 302F (150C). The first fry will cook the potato inside, which shouldn’t take more than 5 minutes. Simultaneously, the thin outer layer will form, which will result in crispy fries in the second fry. The second fry should always happen with cold potatoes and hotter oil. When the potatoes are blanched the first time, you should always cool the potatoes thoroughly. Only when they are completely cold proceed with the second fry. Oil for the second fry should be preheated to 356F (180C). Hotter oil will make the other layer brown and crispy.
- Put a sheet of parchment paper on a baking dish
- Place blanched fries onto a baking pan
- Preheat the oven to the highest temp possible on ventilation function
- Bake for about 10-20 minutes until golden brown
- Always put salt on already baked fries because if you salt unbaked, they will release water and won’t come out as crispy
- Preheat the oil in your deep fryer
- Place blanched fries into the frying rack
- Deep fry for about 5-10 minutes
- Salt french fries before serving
How much does it cost to make french fries?
There aren’t a lot of ingredients in french fries recipes. The only thing you need are potatoes, oil for frying, and salt. To calculate the cost of making french fries at home, we had to consider all the factors that affected the price.
Measurement to grams: we calculated the measurement of each ingredient into grams to get the sum weight of ingredients for french fries. Since oil is not used entirely in the frying process, only the oil that is absorbed into french fries was calculated.
Average product price: for each ingredient, we checked the latest prices online and calculated the average price of ingredients per ounce, which are included in the french fries recipe.
Price per ingredient: the price for each ingredient is calculated to match the amount used in the recipe:
- The price for potatoes is calculated for unpeeled potatoes. Example: the recipe calls for 10 large potatoes, which is 3680g. The average price per 1lb of potatoes is 0,78$. If 1 lb is 0,78$ then 3680g is 6,5$. Meaning 10 large russet potatoes in french fries costs 6,5$.
- The price for oil is calculated on the fact that oil can be used at least 10 times with the hypothesis that you only use oil for frying potato fries or chips and not breaded or battered foods.
Sum weight of french fries: the summed weight of all ingredients for unfried french fries in grams is calculated with unpeeled potatoes and only absorbed amount of oil in potatoes. This is how we can compare the weight of unfried store-bought french fries to the unfried homemade french fries recipe.
- Russet potatoes calculation: To compare the weight of russet potato ingredient to frozen french fries, we took the total unpeeled weight of the potatoes. The hypothesis is that when you buy a frozen bag of potatoes in a store, you purchase unpeeled frozen potatoes. The hypothesis for calculating the total weight of unpeeled potatoes was that the weight of potatoes is reduced by 10% after they are peeled.
- Oil calculation: To compare the weight of oil, we took into consideration the fact stated in a book Food Engineering – Volume III: approximately 10% of oil is absorbed in the frying process.
If you make french fries in the oven, we took into calculation only 6 tbsp of oil. When making french fries in the oven, less oil is used than if you deep fry it.
Electricity cost: We made calculations for making french fries in a deep fryer with an average power of 800 watts and in the oven with an average power of 2400 watts.
- The deep fryer idle energy rate is approximately 800 watts. If we use a deep fryer for 10 minutes, we spend 0,02$ for electricity on average electricity rate.
- Ovens use 1000 to 5000 watts, with an average modern oven using around 2400 watts on medium to high heat.
- The calculation also includes the average electricity rate in the USA which is 13.19 cents per kilowatt-hour (updated April 2020)
Time, utensils, and cookware: We did not include time cost or the purchase of cookware and tools into the calculation.
