Preheat your oven to 425°F and line a baking sheet with parchment paper.
Slice the russet potato into thin, even matchsticks to ensure they crisp up properly.
In a small bowl, toss the potato strips with olive oil, minced garlic, and a pinch of sea salt.
Spread the fries in a single layer on the baking sheet and roast for 20-25 minutes, flipping halfway through, until golden brown.
While the fries roast, combine the ground beef with garlic powder, salt, and black pepper in a bowl, then form into one thick, uniform patty.
Heat a non-stick skillet over medium-high heat and sear the beef patty for 4-5 minutes per side until cooked through.
Lightly toast the whole wheat bun in the same skillet for 30 seconds until warm and slightly crisp.
Assemble the burger by placing the patty on the bun base, topping with the romaine leaf and tomato slice, and serving with the hot garlic fries.
