How can I make sweet potato fries soggy?

the reason you haven't found any recipes for soggy sweet potato fries is because of one simple fact: soggy is the default state for oven fries, unless you do something to specifically make the crispy.

So, in search of non-crispy fries, here is a list of things you could try:

• Cook at a low temperature; over 400°f makes crispy fries, so closer to 350°f will prevent crisping
• Don't overcook them; oven fries must first dry out before they get crispy, so to avoid that simply take out your fries as soon as they are cooked through
• Don't use too much oil; oil helps fries to ... "fry" ... use only a little to prevent sticking
• Steam your fries afterwards; after you take them out of the oven they will be very hot and will release steam, simply cover with tin foil ... a lid ... a pan ... anything
• Try cooking them in the microwave instead of the oven

hope this helps

p.s. sriracha mayonnaise is a great dip for sweet potato fries

Here's a life hack for you:

When heating your oil, constantly poke a chopstick into the heating oil to touch the bottom of the pot/fryer. When micro bubbles begin to come out of the tip of the chopstick when you make it touch the bottom of the pot in the oil, it should be the right temperature to fry soggy fires.

If you are going to use the standard frying temperature, to make sure that your fries turn out nice and soggy, try to give each and every potato cut little to no personal space in the fryer. This will slow down the heating process and make for soggy fries.
