Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets with half of the olive oil, salt, and pepper, then roast for 15-20 minutes until the edges are crispy and charred.
Boil the cubed potatoes in a pot of salted water until fork-tender, about 12 minutes.
Drain the potatoes and mash them thoroughly with the minced garlic and a splash of hot water or broth until creamy.
Season the steak with salt, pepper, and the coconut sugar to help create a deeply caramelized crust.
Heat the remaining olive oil in a cast-iron skillet over medium-high heat and sear the steak for 3-4 minutes per side for medium-rare.
In the same skillet, crack the egg and fry it until the whites are set but the yolk remains velvety and runny.
Plate the garlic mash and broccoli, top with the sliced steak, and crown it with the fried egg.
