- Easily customisable.
🛒 Ingredients

- Brussels Sprouts - I prefer to use small bright green Brussels Sprouts as they are sweeter and more tender than their larger counterparts. If you have large sprouts, it's best to halve them.
- Chorizo - cured chorizo sausage gives the sprouts a delicious smoky flavour.
- Chestnuts - vacuum-packed chestnuts give the dish a nutty flavour and added texture.
- Olive Oil - for roasting. Thanks to using chorizo, which releases its oils on cooking, only 1 teaspoon is needed.
🔪 How to roast Brussels Sprouts to crispy perfection!
The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post
Step 1: Bring a pan of salted water to the boil and parboil the prepared sprouts for 3 minutes (set a timer from when they entered the boiling water). Drain and steam dry.
💡Pro Tip - preparing sprouts: Cut off the tough stem and remove any loose leaves. Leave smaller sprouts whole, and halve larger sprouts with a sharp knife.
Step 2: Toss the Brussels sprouts with the chopped chorizo, chestnuts, and olive oil. Season and place in a baking tin.
Step 3: Roast the sprouts in a preheated oven for 20 minutes until the insides are tender and the outsides are golden and crispy. Shake halfway through cooking.
💭 Top tips
- Try to ensure the Brussels sprouts are in one layer in the baking tin to ensure they roast evenly and are crispy all over.
- Make sure your sprouts have steam dried fully after parboiling, to guarantee your roasted sprouts are crispy and caramelized (not soggy and steamed).
- Leave small sprouts whole and half any large sprouts for even cooking.
- If you're using small whole sprouts you can skip the parboiling step, especially if you don't mind them having an al-dente bite to them.
🍴 Serving suggestions
Roasted Brussels Sprouts are a delicious vegetable side dish, and we always have them for Christmas lunch, alongside roast turkey AND beef, polenta roast potatoes, garlic sweet potato mash, slow cooker red cabbage, cauliflower cheese, honey roast parsnips and carrots, bread sauce, devils on horseback, and sausagemeat stuffing! It's no wonder we're always stuffed!
They're also great with creme fraiche chicken, slow cooker pork chops, or easy sausage casserole for an easy midweek meal!

📖 Variations
- Roasted Brussels Sprouts with Parmesan and Garlic - add 1 crushed garlic clove and 2 tablespoons of grated Parmesan to the roasting pan for even more flavour.
- Roasted Brussels Sprouts with Bacon - swap the chorizo for bacon.
- Roasted Brussels Sprouts with Balsamic and Honey - drizzle over 1 tablespoon of balsamic vinegar and half a tablespoon of honey 5 minutes before the end of cooking.
- Make them vegetarian-friendly and leave out the chorizo.
- Like spice? Add 1 teaspoon of chilli flakes, or red pepper flakes to the roasting tin.

🥡 Storage
Store: Place the roasted Brussels Sprouts in an airtight container and store them in the fridge for up to 3 days.
Reheat: Reheat in the oven for 5 minutes to retain their crispiness, or microwave until piping hot.
Freeze: Cooked sprouts can become soggy if frozen, I don’t recommend freezing roasted Brussels sprouts.
💡 Pro Tip - make-ahead: I recommend preparing and parboiling the sprouts in advance (do this up to 24 hours ahead and store in the fridge), and then serve straight from the oven once roasted.
❓ FAQs
Brussels sprouts are packed with nutrients! Notably, they contain high levels of vitamin C, fibre, and kaempferol.
I don't recommend roasting Brussels Sprouts without oil as they are likely to burn. You don't have to use olive oil, any type of oil that is suitable for cooking can be used.
I don't recommend roasting them together as they have differing cooking times. Potatoes take much longer to cook than sprouts.

Parboiling the sprouts is such a good idea and my kids finally like my roasted Brussels Sprouts! The texture is perfect. I tried the parmesan and garlic and will try chestnuts for the holidays.

Brussel sprouts with pork is the only way I’ll eat them. Usually I add bacon, but it’s amazing with chorizo. Thanks for the idea!
