Slice the potatoes into long, 1/2 to 1 inch thick slices (or desired fry shape).
Rinse the sliced potatoes in a strainer.
Preheat oven to 425°F (you can also use an air-fryer for easier cooking). Prepare a large baking sheet with parchment paper.
Spread fries evenly on prepared baking sheet (make sure they are not overlapping - you may need a second baking sheet if they don't all fit). Place in the preheated oven or air-fryer and bake for 35-45 minutes, flipping halfway. If necessary, cook longer until desired crispiness.
In a small bowl, mix the garlic powder, onion powder, lemon pepper and olive oil.
Once the fries are finished baking, pour lemon pepper mixture over fries and toss to coat evenly.
Sprinkle with extra lemon pepper and desired seasonings.
Serve with a side of ketchup, vegan ranch, or any of your favorite sauces!
