Begin by preparing the sweet potato: wash and peel it, then cut it into fries. Place the fries in the air fryer or on a baking sheet if using the oven.

Cook the sweet potato fries according to your air fryer or oven instructions, typically around 20-25 minutes, tossing halfway through for even cooking.

While the fries are cooking, shape and season the hamburger patty. Heat a skillet or grill over medium-high heat, then cook the meat until it reaches your desired level of doneness, usually about 4-5 minutes per side.

In the last few minutes of cooking the burger, warm the hamburger buns on the grill or in a toaster until lightly toasted.

Once everything is cooked, assemble your burger: place the lettuce and sliced tomato on the bottom half of the bun, followed by the cooked hamburger patty, and finish with a drizzle of ketchup.

Serve the assembled burger alongside the sweet potato fries for a delicious meal. Enjoy your creation!
