What is nicer than preparing vegetables in the right season. So many healthy vegetables make their entry during the fall and winter months. Both butternut squash and Brussels sprouts are great to serve as a side dish during these months. And what makes them even better is that their flavours pair really well together to make a delicious vegetarian side dish.

Unfortunately, many people dislike the taste of Brussel sprouts as they can have a very nasty and bitter taste. I never used to like them, until I discovered that depending on the way you cook them, they can taste really nice. Most people who make a Brussel sprouts recipe will just boil or steam them, but for me, this only serves to enhance the bitter taste. Meanwhile, roasting them brings out a delicious slightly sweet aroma which is very palatable. Combining the Brussels sprouts with roasted butternut squash brings out this lovely roasted and sweet aroma. You’ll love it, you really will.

How to make roasted butternut squash and Brussels sprouts

Note: All the exact quantities of the ingredients can be found in the recipe card at the bottom of this post.

It doesn’t get much easier to make this oven roasted Brussel sprouts and butternut squash recipe. In fact, it’s very quick to make in just under 30 minutes. Only the cleaning and chopping of the vegetables take a bit of time. I also decided to make the beautiful flavours of the vegetables themselves the hero’s of the day by not adding too many additional herbs, spices and other ingredients.

Start by preheating the oven to 400°F (or 200°C), then rinse the Brussels sprouts with cold water and remove the yellow leaves. Trim the bottom end and cut in half. Peel the butternut squash and cut in bite-size chunks of about 1 inch or 2.5 cm. Make sure the butternut cubes are similar in size to the Brussel sprout halves to ensure the same roasting time and even cooking. Peel and finely slice the garlic cloves.

Combine everything in a non-stick baking or oven tray. Add a little bit of extra virgin olive oil, salt and pepper to taste and toss to evenly coat everything. Place a few fresh rosemary sprigs on top of the dish and place in the oven.

Roast for 20 minutes and check with a fork if both the vegetables are tender. If not, leave to roast for another maximum 10 minutes. The exact cooking time will depend on your oven as well as the size of the vegetables. Serve immediately.

Recipe variations

As I already mentioned before, this recipe is simple with minimal extra ingredients which allows the lovely taste of the butternut and Brussels sprouts themselves to really shine. If you’d like to make it more exciting, here are some additional ingredients to add to this side dish recipe.

  • Bacon: Even though it is a side dish, a few bacon bits will lift up the dish and add an extra savoury hint.
  • Cinnamon: Butternut and cinnamon is a great combination and is used a lot together. Cinnamon compliments the sweet taste of the roasted butternut and gives this dish some extra punch.
  • Maple syrup or honey: Another sweet flavour to elevate the taste and aroma of this recipe. Drizzle some maple sirup or honey over the vegetables during the last 10 minutes of the roasting time to avoid burning of the syrup while roasting.
  • Pecans: Sprinkle some chopped pecans over this dish before serving. This will provide a delicious nutty taste as well as some extra crunch. Consider roasting them in a dry pan to soften them ever so slightly.
  • Herbs: Experiment with various other fresh herbs instead of rosemary. Add some sprigs of fresh thyme instead of the sage leaves.

Can you make this dish ahead of time?

It is best to serve immediately, however, this recipe can also perfectly be made in advance. After roasting, leave to cool and store in the fridge in an airtight container.

Re-heat in the oven by placing the ingredients on an oven tray and leaving them in there for 10-15 minutes on low heat until warm. Do not put the heat too high as they will start roasting and cooking again with the risk of being overcooked. You can also warm them in the microwave oven.
