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 is in season in your area with this Seasonal Food Guide.

Cast Iron Asparagus Tips and Tricks



How to Keep Asparagus Fresh

Once you snag your asparagus and bring it home, you can easily keep it fresh for up to 7 days if you store it correctly.

Place the asparagus tips facing up in a glass jar and fill it with about 2-3 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 fridge. This freshness-preserving technique works with white and purple asparagus as well!

Prep Your Asparagus

Asparagus is notorious for having tough-to-chew “woody” ends. Make sure to break those ends off before roasting your asparagus for the best bite.

Still, don’t throw out those asparagus ends! You can compost them or save them in the freezer along with your other veggie scraps to make your own vegetable broth.

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

Get Water Hot in the Cast-Iron Pan

Place your cast-iron pan over high heat. Add the water and allow it to heat until you notice it starting to simmer.

Add Your Asparagus

Once your water is simmering, add your asparagus, doing your best to place it in a single layer.

Place the lid on your pan and continue to heat on high for 90 seconds. This will trap the steam and steam the asparagus to retain its crisp texture and bright green color.

After 90 seconds, remove the lid and continue to simmer until most of the water has evaporated.

Add the Oil and Seasoning

Once the water has evaporated, add the oil, salt, and pepper and toss. Continue to cook on high, tossing occasionally, until there’s a little char on your asparagus.

Should You Have Leftovers

This Cast-Iron Asparagus will stay fresh in the refrigerator for 2-3 days. You can also opt to freeze it for 2-3 months. Just make sure to allow the asparagus to cool completely first before adding it to a freezer.

To reheat the asparagus, preheat your oven to 350°F. Add your asparagus to a baking sheet (you can line it with parchment paper or reusable baking mat for quicker cleanup) and roast for about 10 minutes or until heated thoroughly.

Alternatively, you can reheat the asparagus in a cast-iron skillet over high heat for about 8-10 minutes until hot.

Cast Iron Asparagus Frequently Asked Questions



What is the best way to cook and eat asparagus?

There are two great ways to cook asparagus, depending on how you were eating it.

Asparagus makes a delicious side dish, addition to a salad, or as an add-in to your favorite pasta dish and more!

If you want to keep the crisp and freshness to your asparagus, make this cast-iron asparagus! If you want more tender asparagus, I like it roasted.

Do you rinse asparagus before cooking?

When preparing your asparagus, it’s best to rinse it before cooking it. It can often have dirt or similar which can give it a gritty texture. Additionally, it can have residual fertilizers, pesticides, and preservatives on it if it’s not organic.
