Roasted Broccoli and Cauliflower is what I make when I want a side dish that pairs with everything. Roasted until golden with breadcrumbs, then finished with lemon and mint, it comes together in 25 minutes. This recipe pairs beautifully with a main course like my Lemon Chicken Thighs and is the weeknight side that also earns a spot at a holiday table.

If you're already a cauliflower person, this isn't the only way I roast it. My Roasted Cauliflower With Tahini leans warmer with cumin and a creamy lemon tahini sauce, while my Roasted Cauliflower Salad turns the same caramelized florets into a heartier dish with arugula and cheese. If the mint in this recipe wins you over, my Fresh Mint Pesto is worth keeping in your back pocket. It's just as good spooned over roasted vegetables like this recipe for roasted broccoli.

This is one of those sides that goes with almost anything, but a few pairings are in regular rotation at my table. For something bright and simple, I love it next to my Mediterranean Salmon Baked. When I'm hosting, it's perfect with a heartier main like Lamb Moussaka, where the bright lemon and mint cut through the richness. On a busy weeknight, it comes together fast enough to round out my Chicken Thighs without any extra effort.
Key Ingredients
You will need the following ingredients to make this oven roasted cauliflower and broccoli:
- Olive Oil - Regular olive oil, not extra-virgin, is what you want here. I tested this with extra-virgin olive oil first and found it just doesn't hold up at 400°F for 20 minutes. Its smoke point is too low for the extended roast, and you lose flavor instead of gaining it. A plain olive oil or avocado oil gets you a cleaner roast and lets the garlic and breadcrumbs be the stars.
- Breadcrumbs - The breadcrumbs go on at the 15-minute mark, not before. I tried adding them at the start and they turned soggy long before the vegetables were done, since the broccoli and cauliflower need that first stretch of roasting to release their moisture. Adding them halfway through gives you a crisp, golden topping instead of a mushy one. This is the detail that makes the dish, and it's the one most other roasted broccoli and cauliflower recipes skip.
- Fresh Mint - Mint is what keeps this from tasting like a straightforward roasted vegetable side. It's what pulls the dish into Mediterranean territory alongside the garlic and lemon. I do recommend fresh herbs here. If you only have dried, use about a teaspoon and rehydrate it briefly in a little water or lemon juice first, or you'll end up with dry flecks sitting on top of the vegetables instead of real flavor.

Variations
- Broccoli or cauliflower - Use all one or the other if that's what you have, just keep the total volume the same.
- Garlic powder - A small clove of fresh garlic works in a pinch, though I tested this recipe with fresh garlic first and found it overpowered the dish. Garlic powder gives a more balanced result.
- Mint - Swap in fresh parsley or dill if mint isn't your thing.
- Spicy - Add a pinch of red pepper flakes to the breadcrumb topping for heat.
- Serve cold - The roasted flavor holds up well chilled, and the mint leans even brighter served this way
How To Make Roasted Broccoli and Cauliflower: Step-By-Step
Here are some quick visual instructions. Remember that full instructions with the exact ingredients are in the printable recipe card:
Step 1: Preheat your oven to 400°F. Line a baking sheet with parchment paper.
Step 2: In a large bowl, toss the broccoli and cauliflower with the olive oil, salt, garlic powder, and black pepper. Spread onto the baking sheet in a single layer and roast for 15 minutes.
Step 3: Remove the baking sheet from the oven. Sprinkle the breadcrumbs over the vegetables and use a spoon to coat the florets evenly. Return to the oven and roast for another 5 minutes, until the vegetables are fork-tender, the edges are starting to char, and the breadcrumbs are golden.
Step 4: Remove from the oven. Toss the hot vegetables with the lemon juice and mint. Serve warm.
Gwen's Pro Tip
Add the breadcrumbs at the 15-minute mark, not before. That timing gives you a crisp topping instead of a soggy one, and it's the single detail that separates this from a basic roasted veggie side.
Roasted Broccoli and Cauliflower FAQ's
This comes down to steam instead of dry heat. Make sure your florets are dried well after washing, and don't crowd the baking sheet. If you're scaling the recipe up, roast in batches rather than piling everything onto one pan.
Yes, with two adjustments. Don't thaw them first. Toss them straight from the freezer. Then, extend the first roasting time from 15 minutes to 20 to 25 minutes. Frozen vegetables carry more water and need the extra time to roast instead of steam.
