Preheat the oven to 375°F and line a baking sheet with parchment paper.
In a large bowl, combine the ground beef, sun-dried tomatoes, basil, panko breadcrumbs, egg, onion, salt, and black pepper. Mix with your hands until evenly distributed.
Divide the mixture into four equal portions and shape each into a small loaf. Place the loaves on one side of the prepared baking sheet.
In the same bowl, toss the broccoli florets with olive oil, minced garlic, and a pinch of salt. Spread the broccoli on the other side of the baking sheet.
Bake for 25 minutes. Remove the sheet from the oven and sprinkle Parmesan cheese over the broccoli. Return to the oven for 5 more minutes until the cheese melts and the broccoli edges turn golden.
