In a shallow tupperware or Ziploc bag, add steak, lemon juice, 3/4 cup olive oil, garlic, and salt and pepper. Stir or shake to combine. Place in refrigerator and let marinade for 1-2 hours.
Preheat oven to 425 degrees.
Place russet potatoes in a single layer on a foil-lined baking sheet and drizzle with 1/4 cup olive oil. Toss with hands to coat all the potatoes with oil. Sprinkle with garlic powder, paprika and salt and pepper.
Bake for 25 minutes, turn them over, and bake for an additional 25 minutes (or until golden brown and cooked all the way through).
Remove steak from the refrigerator and cook in a skillet over medium-high heat until it reaches desired doneness.
Place potatoes on an oven-safe dish and top with steak and cheese. Broil for 3-5 minutes until cheese is melted.
Top with pico de gallo, guacamole, and sour cream. Serve warm.
Notes
If you like a really crispy fry, you can broil your baked french fries for 1-2 minutes after baking them.
