A Quick Note from My Kitchen
I started making this roasted broccolini many years ago, but I make it more often since I started my weight loss journey with Mounjaro. It is one of my favorite vegetables, especially in the cooler months when I crave something warm, bright, and easy. It’s tender, full of flavor, and never boring. I serve it next to chicken, salmon, or pork, and I honestly never get tired of it.
Why This Roasted Broccolini Recipe Works
Broccolini, sometimes called baby broccoli, roasts beautifully in the oven. It gets crisp-tender, slightly charred at the edges, and absorbs flavor like a sponge.
Tossing it in a lemon-garlic oil mixture before baking allows the garlic to mellow, the red pepper flakes to add a subtle kick, and the lemon zest to brighten every bite. Finishing it with a squeeze of lemon juice and Parmesan? That’s the chef’s kiss.
If you’ve never tried oven-roasted broccolini, you’re in for a treat. It’s quicker than steaming and ten times more flavorful.
Ingredients You’ll Need

Here’s what goes into this easy roasted broccolini side dish:
- Broccolini – Also known as baby broccoli. It’s sweeter and more tender than regular broccoli. Trim the ends and split thick stalks for even roasting.

- Garlic cloves – Fresh and finely minced so it doesn’t burn.
- Red pepper flakes – Add a little heat. Adjust to your taste.
- Salt – Balances the bitterness of the greens and enhances flavor.

Expert Tips for Roasting Broccolini
- Don’t overcrowd the pan – Broccolini needs space to crisp. Use two sheet pans if needed.
- Zest before you juice – It’s nearly impossible to zest a squeezed lemon.
- Don’t skip the drying – Damp broccolini will steam, not roast.
- Watch the garlic – Toss it into the oil mixture so it sticks to the broccolini and doesn’t burn.

FAQs About Oven Roasted Broccolini
They’re essentially the same thing. Both have longer stems and smaller florets than regular broccoli, and are more tender and less bitter.
Yes, but cut it into small florets and reduce roasting time slightly (14–18 minutes) to avoid overcooking.
Not at all. You can skip it or try something different. For a salty, savory kick, try crumbled feta or goat cheese, both melt slightly on the warm broccolini and add a creamy contrast.
If you want something bold and nutty, aged Manchego or sharp white cheddar shaved thinly can also work beautifully. Even a little blue cheese can be delicious if you’re pairing this dish with steak or grilled meats.
Yes. Cook at 375°F for about 10–12 minutes, shaking halfway through. Keep an eye on the garlic to prevent burning.
If you are using a lower oven temp, roast for 25 minutes instead. It won’t get quite as crispy but will still be tender. The secret to a crispy, roasted broccolini is the high temperature.
