Oven Roasted Broccoli with Lemon Butter
This post may contain affiliate links. Please read my disclosure policy.
The best roasted broccoli recipe includes broccoli florets and chopped tender stalks, baked in the oven with garlic, butter, and olive oil until browned and tender. I double down on lemon because it pairs so well with broccoli, using grated zest and freshly squeezed juice. Finish the dish with a shower of shaved Parmesan cheese and dig in!
Roasting broccoli is not only one of the most approachable ways to cook this ever-popular vegetable, but a hot oven really helps to amplify its earthy-sweet flavor.
I find it as seriously comforting as a bowl of homemade broccoli cheddar soup on a rainy day.
FYI — there’s no need to boil broccoli before roasting. It goes straight onto a baking sheet with a good drizzle of olive oil, chunks of butter, and grated lemon zest. Add a squeeze of fresh lemon juice and finely chopped garlic during the final minutes of baking, when the veggies have crisp edges and are tender to the bite.
Notes on the ingredients
- Fresh broccoli: You’ll need 2 heads of broccoli, which will give you about one and a half pounds after trimming. This amount of broccoli fits perfectly into a quarter-sheet pan.
- Lemon: This recipe uses fresh zest and some of the juice from one lemon.
- Butter and olive oil: I use a half-and-half mixture of olive oil and butter — the oil helps prevent the butter from burning in the oven, and the butter just tastes delicious!
- Parmesan cheese: I’m very much into wide ribbons of cheese melting on top of the just-roasted broccoli. If you have a chunk of Parmesan, shave off big curls using a vegetable peeler or use the large holes on a box grater to create coarse shreds. If this seems like too much, you can also use regular grated Parmesan.
- Garlic: One or two cloves of fresh garlic — finely chopped or grated on a rasp grater (such as a Microplane) — adds all the flavor.
How to make roasted broccoli
1. To prep the broccoli: Slice off and discard the tough lower third of the broccoli stem, separating it from the crown 2. Cut the broccoli florets into bite-size pieces. Dice the remaining light green tender stems and stalk.
3. Spread the broccoli out in an even layer on a rimmed baking sheet. Drizzle with olive oil and toss with lemon zest, salt and black pepper. Distribute the cubed butter evenly over the top. 4. Bake or roast at 400 degrees for 15 minutes. Stir in the garlic and a squeeze of lemon juice. 
5. Return to the oven and roast 5-10 more minutes. Sprinkle the Parmesan over the hot broccoli. Serve it up!
Best oven temperature for roasting broccoli
- I love the charred edges of vegetables (see this broccoli salad recipe for proof), but for this recipe, I wanted to achieve perfect tenderness along with the browned nooks and crannies. Baking the broccoli at 400 degrees for 20-25 minutes is the key.
Serving ideas
- Make a batch of roasted broccoli as a side dish for roasted whole chicken.
- Toss with pasta for a simple dinner.
- Add to grain bowls or salads for weekday lunches.
