What Temperature Should Vegetables Be Cooked At?

Many cooks and chefs debate about the ideal temperature to cook vegetables. While some argue that a lower temperature preserves the natural flavor and texture of vegetables, others believe that a higher temperature is needed to fully cook the vegetables and release their natural flavors. 

Ultimately, the ideal cooking temperature for vegetables depends on several factors, including:

  • The type of vegetable 
  • The level of softness desired 
  • The cooking method used

For instance, roasting vegetables like potatoes at a higher temperature, such as 425°F, can help give them a nice crispy texture on the outside, while also being soft and fluffy on the inside.

However, if you do cook your potatoes at this temperature, we do recommend that you lightly boiled them first, just so they are cooked all the way through!
