Slice potatoes into fries. Place on a large baking sheet. Pour about 1 tablespoon of oil over the fries and toss with fingers to coat evenly. Sprinkle fries with seasoning of choice. I use seasoned salt. Place in the oven. Bake for approximately 45 minutes or until golden and crispy.
In a mixing bowl, mix hamburger, garlic, seasoned salt, onion powder and salt and pepper. Mix well with hands. Form 4 large patties. I like to make really rustic, greasy diner-style patties with no uniform shape. Place in a large preheated skillet over medium heat, preferably one with deep sides. Brown burgers on each side until done.
Remove burgers from the skillet and place on a plate covered in paper towels. Do not drain the grease. Add the flour a tablespoon at a time, stirring with a whisk. You have enough when the grease is all absorbed and the flour mixture gets thick and bubbly. Slowly add the broth a little at a time, whisking constantly. Bring to a simmer and allow to thicken.
To serve, place an ample amount of fries on the plate. Place a hamburger on top of the fries and cover it all amply in gravy. Enjoy!
