There are probably a hundred different ways to roast broccoli, but this method is my favorite. It’s ready to eat in about 20 minutes and develops caramelized, crispy edges that you’ll crave.
Preheat the oven to 400ºF and lightly grease a half-sheet pan with oil. Using a cutting board and sharp knife, cut the broccoli florets into similarly sized pieces. I like to cut the stems in half, so each piece has a flat side.
Transfer the cut broccoli to a large bowl and toss with the olive oil, garlic powder, and salt. Use your hands to rub the seasonings evenly into each piece, then spread the broccoli out on the prepared pan. Ensure the flat side of each piece is in direct contact with the pan, and don't crowd the pieces. (Otherwise they will steam, rather than crisp up.) Bake at 400ºF for 15 to 20 minutes.
You'll know it's time to check on the broccoli when your kitchen smells fragrant. A fork should easily slide into the pieces when they are tender, and the edges will look golden brown. Serve warm right away for the best texture.
Notes
Nutrition information is for a quarter of the batch. This information is automatically calculated using generic ingredients, so it's just an estimate, not a guarantee. Flavor Variations: Add a teaspoon of lemon juice for a brighter flavor before roasting. You can also add 2 to 3 tablespoons of Parmesan cheese to the broccoli before cooking it. (Or sprinkle it on after roasting for an extra salty, cheesy flavor.)
