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.
