Prep the Fries: Start by peeling the potatoes. Slice them lengthwise into thin planks, then cut those into ¼-inch strips for that perfect fry shape.
Soak the Potatoes: Fill a large bowl with cold ice water and soak the potato strips for 10-15 minutes. This helps remove excess starch for crispier fries.
Season the Steak: While the potatoes soak, generously season both sides of the steak with salt and pepper. Let it sit at room temperature.
Preheat the Oven: Set the oven to 425°F (220°C).
Dry and Season the Fries: Drain the potatoes and pat them completely dry with a kitchen towel. Toss them in a large bowl with olive oil, salt, pepper, garlic powder, and oregano until evenly coated.
Bake the Fries: Spread the fries out in a single layer on a baking sheet lined with parchment paper. Bake for 30 minutes, flipping halfway through. Broil on high for the last 5 minutes to get them extra crispy.
Add Parmesan and Parsley: While the fries are still hot, sprinkle them with shredded parmesan and chopped parsley for that garlic parm magic.
Cook the Steak: Heat a skillet over medium-high heat. Add Beef Tallow or oil. Sear the steak's fat cap for 1 minute, then sear each side for 2-3 minutes (adjust based on your preferred doneness). Rest the steak for 5-7 minutes before slicing it into strips.
Assemble and Serve: Pile the garlic parmesan fries onto a serving platter, top with steak slices, and drizzle with lemon herb aioli. Sprinkle chopped chives for a fresh finish. Dig in and enjoy!
