This Oven Roasted Broccoli will be the star of your dinner

Like balsamic green beans, broccoli is a vegetable my family eats every single week, without fail. So it’s strange that out of nearly 700 published posts, only 4 of them, including salmon Alfredo, feature broccoli at all, and broccoli isn’t the *star* of any of them.

Broccoli CAN and SHOULD be a star on your dinner plate. It doesn’t have to be boring. It doesn’t have to be bland. It doesn’t have to be diet food.

Just like roasted glazed carrots, this Roasted Broccoli with Lemon and Parmesan is so good that there won’t be a single bite of leftovers when you serve it, I promise you. Adults and kids alike (with some simple modifications) will gobble it down.

The combination of roasted brown goodness on the broccoli, combined with Parmesan cheese, lots of lemon zest and juice and red pepper flakes will earn this a permanent spot in your side dish rotation.

Why you’ll love this Roasted Broccoli with Parmesan

Roasted broccoli tastes better than steamed broccoli because roasting the vegetable browns it and adds a caramelized, nutty flavor, while steaming it doesn’t add any flavor at all.

Additionally, roasting allows the broccoli to become slightly crispy on the outside while still tender on the inside, which is the perfect combination of textures. Steamed broccoli is, more often than not, kind of mushy all the way through.

So, just like my roasted acorn squash slices, this lemon Parmesan roasted broccoli recipe cooks the broccoli by roasting it from start to finish. No steaming needed here at all.

Ingredients laid out on a light surface, including fresh vegetables, olive oil, salt, lemon juice and zest, cheese and red pepper flakes.

 Ingredients for Parmesan Roasted Broccoli

  • broccoli – this nutritious and versatile vegetable is the star of this dish. Depending on how much broccoli your family eats, you’ll need 1 or 2 heads of broccoli. My family LOVES broccoli, so we can eat 2 medium heads of it in one dinner!
  • olive oil – use a high quality olive oil to add a depth of flavor and help the lemon Parmesan broccoli crisp up.
  • kosher salt – this is essential to bring out the broccoli’s best flavor!
  • Parmesan cheese – you can use grated or shredded. Either variety adds a nutty, salty flavor to the dish, as well as Greek yogurt pasta sauce and my crab-stuffed salmon recipe.
  • lemon juice AND zest – be sure you zest your lemon before you juice it, because just like with my lemon smoothie, we’re using the whole thing for lemon roasted broccoli! Using both adds a well-rounded brightness and acidity to the dish.
  • red pepper flakes – these are optional, but add a touch of heat to the roasted broccoli.

How to make Roasted Parmesan Broccoli

  1. Preheat your oven.
  2. Trim the thick stems from the broccoli. Use a veggie peeler to peel the stems, and then cut the stems into disks.
  3. Cut the broccoli florets into 1-1/2-inch pieces.
  4. Divide the broccoli between 1 or 2 rimmed baking pans. The broccoli should be in an even layer and not crowded, so when in doubt, use 2 pans!
  5. Drizzle the broccoli with oil and season it with salt, then toss with your hands to combine everything.
  6. Roast 20 to 25 minutes or until the broccoli is brown and tender. Try to stir it once halfway through cooking.
  7. Transfer the broccoli to your serving bowl and add the cheese, lemon juice and zest and red pepper flakes, if you’re using them. Toss everything together and serve right away.

How to cut broccoli for Parmesan Roasted Broccoli

The first step is to trim the lower, thick stems from the broccoli. But don’t throw them away, just set them aside.

Cut the crown of the broccoli into florets that are all similar in size. I suggest about 1-1/2 inch pieces, which are good bite-size pieces.

Then, go back to your stems. Use a vegetable peeler to peel the outer rough parts of the stems, and then slice the stems crosswise into 1/4-inch-thick disks. They’ll cook up tender in the oven and be so delicious, trust me.

For the best lemon roasted broccoli, do NOT crowd the pan.

If you’ve ever Googled “why is my roasted broccoli soggy?,” I’m here to help you. The #1 reason your broccoli is soggy is that you overcrowded the pan it roasted on.

The broccoli pieces were too close together as they cooked, so the broccoli ended up steaming instead of roasting and caramelizing.

So, just like with balsamic roasted carrots, use your best judgement and divide your broccoli florets and stem slices between 1 to 2 rimmed baking pans.

The broccoli should be in an even layer and not overcrowded. You want a little room around each piece so it can roast. When in doubt, use 2 pans for lemon Parmesan roasted broccoli.

Roasted Parmesan Broccoli tips

As I mentioned above, the red pepper flakes are entirely optional (and in lemon caper pasta as well). The adults may love the heat they add to the lemon Parmesan broccoli, but if your kids aren’t into them, the great news is they just go on at the end anyway.

Omit them from Step 3, toss everything together and serve, and just offer red pepper flakes at the table for anybody who wants to add them to their portion.

It also works great with a simple protein like orange glazed chicken, fried pork chops, or sockeye salmon. One of my favorite things to pair it with is pistachio crusted chicken.

Roasted Parmesan Broccoli FAQs

Why is my broccoli soggy in the oven?

If your broccoli turns out soggy, it’s likely that you’ve overcrowded the pan. If you place too much broccoli on a single baking pan, it will steam instead of roast. Use 2 pans if necessary to ensure that the broccoli has enough space for proper air circulation.

Why is my roasted broccoli mushy?

Overcooking broccoli can lead to a mushy texture. Monitor it as it cooks and remove the broccoli from the oven once it is golden brown and has crispy edges. It should be tender but not mushy.
