1-First Step: Heat the oven and prep the pan Start by preheating your oven to 400°F (200°C). This matters more than people think, because broccoli roasts best in a hot oven that can brown the edges quickly. While the oven heats, grab a sheet pan and get your broccoli ready. Wash the broccoli well, then dry it completely. Water left on the florets can lead to steaming instead of roasting, which means you lose that lovely crisp-tender bite. A clean kitchen towel or salad spinner works well for drying.

2-Second Step: Cut the broccoli the right way Cut the florets from the thick stalks, leaving about 1 to 2 inches of stalk attached. Discard the rest of the stalks if they are too woody. If any florets are large, cut through the base to separate them into smaller pieces. Keeping the florets close in size helps them cook at the same pace. That way, you do not end up with some pieces burned while others are still too firm.

3-Third Step: Season generously Place the broccoli florets on the sheet pan in a single layer. Add the sliced garlic, then drizzle with 5 tablespoons olive oil. Sprinkle with 1 1/2 teaspoons kosher salt and 1/2 teaspoon freshly ground black pepper. Toss everything well so each piece gets a light coating. Spread the florets back out into one layer. Crowding the pan traps steam, and that keeps the broccoli from browning the way you want.

4-Fourth Step: Roast until crisp-tender Roast for 20 to 25 minutes. Halfway through, flip the broccoli for even browning. The goal is crisp-tender florets with browned tips, not soft broccoli that has gone limp. If you like more color, let it go a little longer, but watch closely near the end. When I make this for family dinners, I usually peek at the 20-minute mark. Some ovens run hot, so the broccoli can finish sooner. If the garlic starts to darken too fast, pull the pan and stir it around so it does not burn.

5-Final Step: Finish with lemon and Parmesan As soon as the broccoli comes out of the oven, toss it with the remaining 1 1/2 tablespoons olive oil, 2 teaspoons grated lemon zest, 2 tablespoons freshly squeezed lemon juice, and 1/3 cup freshly grated Parmesan cheese. The heat melts the cheese just enough to coat the florets without making them soggy. Serve hot right away. This is the moment when the dish really shines, because the lemon wakes up the flavor and the cheese adds a salty finish that tastes amazing with the roasted edges.
