As an environmental scientist, I always try to stick to seasonal eating! It’s one of the easiest (and most delicious!) ways to support local farmers and improve your carbon footprint.

Green tip: Seasonal and local foods have less associated transportation costs and fuel emissions. Check when asparagus and brussels sprouts are in season in your area with this Seasonal Food Guide.

Roasted Brussels Sprouts and Asparagus Ingredients

Here’s everything you need:

  • Asparagus. One bunch of asparagus is usually about 1 pound of asparagus. Fresh or frozen (thawed).
  • Brussels Sprouts. One stem or one package of brussels sprouts is also usually about one pound of sprouts. Fresh or frozen (thawed).
  • Olive oil. To roast your asparagus and brussels sprouts in.
  • Salt & pepper. To season your roasted vegetables.

  • Lemon juice. A little citrus goes a long way.
  • Crushed red pepper. For a little bit of spice.
  • Butter. For extra moisture and a rich, buttery finish.
  • Garlic powder. For the garlic fans out there, who want a quick and easy garlic fix.
  • Grated or shaved Parmesan cheese (or Nutritional Yeast). For cheesiness and a little extra salt.

Roasted Brussels Sprouts and Asparagus Tips and Tricks

How to Keep Asparagus and Brussels Sprouts Fresh

Once you find your beautiful asparagus and take it home, you can easily keep it fresh for up to a week if you store it correctly.

Place the asparagus in a glass jar, tips facing up, and fill it with about 2 inches of water so the ends are submerged.

You can then place a reusable storage bag on top and store the whole jar in your refrigerator. This technique works with white and purple asparagus as well!

As for brussels sprouts, sprouts that are still on the stalk will last a little longer than those that are already separated. Still, most fresh brussels sprouts can last up to a week when stored properly.

The best way to store them is dry in a sealed bag or airtight container in the “crisper” drawer in your refrigerator. Make sure they are dry when you store them. It’s best not to rinse them until you’re ready to roast them.

Green tip: Did you know that 50% of food waste happens at home? Reduce your contribution to food waste by properly storing your vegetables until ready for use.

Prepping Your Asparagus

Asparagus are notorious for having “woody” ends that are tough to chew. It’s best to take those ends off before roasting your asparagus.

But don’t throw those ends out! Save them in the freezer along with your other veggie scraps to make your own vegetable broth or compost them.

The best way to remove your ends is to simply snap them off. Hold the asparagus in two clean hands and break them in two. The asparagus will naturally snap right where the ends start to get tough.

Prepping Your Brussels Sprouts

Just like asparagus, for the best brussels sprouts, you have to trim off the rough ends. The rough end is the part of the brussels sprout right where it was taken off the stalk.

Slice the ends off first. Then, slice the brussels sprouts in half longways. Simple as that!

There is no need to boil your brussels sprouts before roasting them. In fact, roasting them raw in a little bit of olive oil, salt, and pepper is the best way to get them nice and crispy!

Cutting tips off brussels sprouts

Season Your Asparagus and Brussels Sprouts

Once you’ve prepped your asparagus and sprouts, line them up on a large baking tray. For easier cleanup, you can opt to line it with aluminum foil.

Then, drizzle on your olive oil and season the vegetables with salt and pepper.

Toss It

Use clean hands to toss the asparagus and brussels sprouts in the oil and seasoning. This is the best way to ensure they are all evenly coated.

Then, spread the vegetables out in a single layer, ensuring they are not stacked on top of one another.

Toss Again Halfway While Roasting

Once your oven is preheated to 425°F, stick your baking sheet with the veggies on it on the top rack of the oven. Roast for 10 minutes.

Green tip: Get to know your oven! Get an idea of how long it takes your oven to preheat. By not pre-heating the oven too early, you can save energy.

After 10 minutes, remove the baking sheet from the oven and use kitchen tongs or two wooden spoons to toss again. Be careful—it’s hot!

Tossing your veggies halfway through the roasting process will just cook them more evenly and help to avoid them sticking to the baking sheet.

Should You Have Leftovers

These Roasted Asparagus and Brussels Sprouts will last in the refrigerator up to 5 days in an airtight container. They can also be frozen for up to one year.

To thaw, transfer from the freezer to the refrigerator and let them rest in there overnight.

To reheat, bring your oven up to 350°F and roast them again as is (no need to add any extra oil or seasonings) for 8-10 minutes until heated thoroughly.

Green tip: Another great way to reduce food waste is to properly store and reheat your leftovers so you can consume them.

Serving Your Roasted Asparagus and Brussels Sprouts

The fresh and simple flavors of this delicious side dish are complementary to pretty much any dish you throw its way! If you want to spruce it up with a sauce of gravy, try this Shallot Cream Sauce or Hearty Mushroom Gravy over top.

My favorite thing to pair this roasted brussels sprouts and asparagus recipe with is Truffle Mashed Potatoes and Almond Crusted Salmon.
