Why roast brussel sprouts and carrots together
I first came up with this roasted vegetable recipe when thinking of great dishes for feeding lots of people on Christmas day.
There are so many ways you can cook brussels sprouts and carrots, but roasting is my favourite. They roast in around the same amount of time as each other, so why on earth not cook them together in the same pan?
Other reasons I love this dish (and think you will too!):
SO EASY TO MAKE. Just clean and chop the veggies roughly. While they’re roasting in a little olive oil and some herbs, prepare a simple honey mustard balsamic dressing. Warm it to melt the butter, then toss through JUST before serving!
INTERESTING TEXTURE. The brussels are slightly crisp and the carrots caramelised on the outside. The veggies are soft on the inside.
SIMPLE, ZINGY FLAVOURS. We all know brussels sprouts aren’t everyone’s favourite. But mixed with the sweet caramelised carrots and this sweet and punchy dressing, there’ll be no more brussels haters in the house.
QUICK, EASY AND NUTRITIOUS. How can you go wrong?
PREPARE AHEAD. Chop the veggies and cover. Prepare the dressing, ready to warm and pour over the vegetables when roasted.

About the ingredients
Brussels sprouts: Grab a 400-gram (14-ounce) bag. Look for fresh ones with tightly-packed bright green leaves without holes in them.
Carrots: Honestly? Any kind. A regular bag of cheap-as-chips carrots will do, or go fancy with multi-coloured or baby carrots if you prefer. Best to use nice fresh, firm ones rather than the ones that have been hanging out in the bottom of your fridge for a month! (don’t worry we all have some of those)
Olive oil: You’ll need just a couple of tablespoons for roasting. If you don’t have olive oil, any kind of oil will be fine.
Thyme: Just 4 teaspoons of thyme leaves. Use dried if you prefer, but you’ll only need a teaspoon.
Mustard: I usually have Dijon in my fridge, so that’s what I use. But any mustard works. Skip the mustard if you’re not a fan.
Balsamic vinegar: Just a tablespoon for a beautiful contrast with the honey.
Honey or maple syrup: A couple of tablespoons for an irresistible hint of sweet. Which is best? Honestly, just use what you have or prefer. Both taste awesome!
Butter: Warm the dressing slightly so that the butter melts. You’ll only add a tablespoon, but it makes all the difference to the final result.
Salt and pepper: Just a touch!
How to make them
The great thing about these vegetables (apart from how delicious they are) is that you can make them in just a few simple steps, detailed below. For the full printable recipe and video, please scroll down!
Start by preparing the dressing and vegetables. Just mix all the dressing ingredients together and microwave for a few seconds to melt the butter. Set aside!
To prepare the veggies, wash the brussels and remove any scruffy leaves. Slice off the rough top part, then slice in half. Just wash and peel the carrots, then slice into chunks that are similar in size to the brussels.
Line a baking tray with baking paper (not essential but I nearly always do this for easier cleanup). Throw the veggies onto the tray, then toss with 2 tablespoons of olive oil and the thyme.
Roast at a medium high temperature (205C or 400F) for 25 to 30 minutes. The brussels will be browned and crisp in parts and the carrots starting to caramelise. I usually toss the veggies around half way through the cooking time.
Finally, toss the dressing through the hot vegetables and serve immediately.
Helen’s top tips
- Don’t overcrowd the pan. If it’s crowded, the veggies may ‘sweat’ and not brown/caramelise as well.
- Some of the brussels leaves will fall off as you slice them. Throw them onto the tray too! They’ll be lovely and crispy!
- Cooking time can vary in different ovens. Go by the colour rather than by the exact time stated in the recipe. Keep an eye on them. When the brussels are browned and crisp in parts and the carrots are starting to caramelise, they’re done (20 to 40 minutes).
- Carrots can take slightly longer than brussels to cook. If the brussels sprouts look like they’re charring too much, just reduce the oven temperature a little.
Ways to vary them
ADD CHOPPED BACON, CHORIZO OR SAUSAGE! Try this on the most ardent of brussels haters. I’d suggest cooking a few chopped rashers of bacon/chopped chorizo or crumbled sausage separately in a frying pan for 5-10 minutes, then sprinkling it over the dish of veggies before serving. I don’t roast the bacon with the vegetables as it doesn’t need that long to cook.
SWAP HONEY FOR MAPLE SYRUP: This possibly depends on which you already have. But of course maple adds a different flavour dimension!
SPRINKLE OVER TOASTED NUTS. Chopped hazelnuts, pecans, walnuts, pistachios, macadamias, slivered almonds – your choice. Pine nuts work well, too.
SKIP THE NUTS – SPRINKLE OVER CHEESE INSTEAD. Parmesan, feta, blue cheese, brie, goat cheese and potentially other cheeses would go well with this dish, too. Don’t go crazy – a little goes a long way, but my, how delicious!
VARY THE HERBS. This is an easy one. No thyme? No worries. Use dried rosemary, oregano or sage, or fresh basil or parsley scattered over at the end.
ADD A FESTIVE SPIN. Sprinkle with dried cranberries or cherries! Or… here’s a fancy trick… skip the honey and use cranberry sauce in the dressing instead!
JUST SERVE THE VEGGIES PLAIN, WITHOUT ANY DRESSING OR ADDITIONS. Because… why not? Scatter with herbs, salt and pepper and be done with it. Sometimes simplest is best.
How to serve them
The most classic way to serve roasted brussel sprouts and carrots is with some kind of roasted meat and potatoes. In the UK this would be called a roast dinner! If you have an air fryer, you just have to try my 1-hour air fryer rotisserie chicken!
This simple veggie dish would also be perfect for a special dinner such as for Thanksgiving, Christmas or Easter. It simplifies things as there are 2 vegetables cooked together, but not at the expense of flavour.
Lastly, I could see these served as an easy midweek side to go with any kind of main – chicken, steak, fish, or a vegetarian alternative. Try serving them with this truly delicious mustard parmesan crispy chicken, these easy baked chicken thighs, or these copycat Ikea meatballs!
More things to know (recipe FAQ)
Nope. Some people do this, but there’s really no need. Why create more work for yourself when it just isn’t necessary?
On the other hand, if you like your brussels sprouts to be really tender on the inside, do go ahead and blanch them for 5 minutes before roasting. Rinse in cold water and dry well before proceeding with the recipe as normal.
Yes! If you choose to do this, you’ll need to roast for an extra 10 to 15 minutes. Also make sure you chop your carrots a bit larger so that they’re about the same size as the brussels sprouts. This way, the 2 types of vegetables will still be ready at the same time.
This can sometimes happen if the sprouts aren’t drained well after washing or blanching. To be sure this doesn’t happen again, blot them with kitchen paper before roasting. Also make sure you don’t crowd the baking tray. Use two if you need to.
You can certainly wash and prepare the vegetables ahead and put them on the baking tray covered and ready to roast. You can also prepare the dressing ahead and keep it in the fridge until you’re ready to use it.
Once you’ve cooked the vegetables, it’s best to serve them right away while the brussels are still nice and crisp.

So happy to hear this, Janice!
These are awesome every time! I add baby broccoli to ours. The key is to make sure you get the veggies crispy/caramelized. Truly the sauce does all the work at the end. We love it!
This is so wonderful to hear, Tara! Thank you so much for the great feedback, and I love your idea of adding some broccoli to the mix, too! 🙂
Super Easy and super delicious! The dressing really elevates these roasted veggies to the next level! I was concerned the balsamic would overpower but it doesn’t! Followed recipe as written! Easy Peasy! Thanks for your inspiration!
Hello Cher! Thank you so much for the encouragement. I thought the balance of flavors was ‘just right’ too, but it’s fantastic to hear that you agree and it’s not just my opinion. Happy New Year!
