Add about 4 inches of canola oil to a large pot and heat over medium high heat, fitting the pot with a candy thermometer. You want the oil to be at 350 degrees F, so if it continues to rise, turn down the heat a bit underneath.
Cover a large cutting board with paper towels. In a bowl, combine paprika, onion powder, brown sugar, garlic salt, chili powder, salt and pepper.
Scrub sweet potatoes and pat dry with paper towels. Slice as thin as possible using a mandolin or a very sharp knife. Add chips in batches to the hot oil, frying for 4-5 minutes at a time, using a large slotted spoon to turn the chips over while frying. Once chips are golden and crispy, remove with a large slotted spoon (or a kitchen spider) and place chips on the paper towels to drain. After about 30 seconds, sprinkle with the homemade bbq seasoning and toss well to coat. Let cool completely. Make sure chips aren’t piled on top of each other so they can cool and crisp up. Serve immediately!
