How To Buy Asparagus
Long or short, thick stems or thin… asparagus comes in all shapes and sizes! But, buying it isn’t hard. Here is what to look for:
- Look for asparagus bundles that contain asparagus spears that area all about the same diameter.
- Thick or thin? It doesn’t matter – and the thickness has nothing to do with the age of the asparagus. In fact, the thinner spears can often be tougher. I personally like the thicker ones.
- Asparagus should have firm tips, not brushy, open, slimy or discolored.
- I pick asparagus that doesn’t have too much white/light green near the stem end. That’s going to get discarded – or you can wash it and freeze it to make vegetable broth or soups like this Cream of Asparagus Soup.
How to Clean Asparagus
Asparagus grows up through the dirt, and nothing will ruin a dish faster than biting into grit. Wash your asparagus thoroughly and enjoy every bite of this delicious lemon and Parmesan asparagus recipe. Here’s how I do it:
- Snap the woody ends off each spear, one at a time
- Rinse 2-3 spears under fast-running water, with the brushy tips in the stream of water. This will help dislodge any grit. Repeat until they’re all washed.
- Fill a large bowl or pot with enough water that the asparagus are floating. Swish them around vigorously then remove them, leaving behind the water. When the water settles, feel the bottom of the bowl – if there’s grit or sand, you need to wash them again under running water. If the bottom of the bowl feels clean, they are good to go.
How To Make Cold Asparagus Salad with Lemon & Parmesan
- Blanch the asparagus – bring a large pot of water to a rapid boil and add a good pinch of salt. Add the asparagus and bring it back to a boil. As soon as it boils, drain the asparagus and plunge it into ice-water to stop the cooking process. Drain when it is chilled and set aside.
- Make the dressing – whisk together the Dijon mustard and lemon juice until smooth. Slowly add the olive oil in a thin stream, whisking all the while. Add the lemon zest, chopped shallots, and Parmesan cheese.
- To assemble the salad – arrange the asparagus spears on a pretty plate and top with the dressing. Enjoy!
How to Make This Easy Asparagus Salad Recipe Ahead of Time
- First, blanch the asparagus, drain and refrigerate.
- Mix the dressing and refrigerate.
- When you’re ready to eat, whisk up the dressing, assemble the salad and enjoy!
Chef Jenn’s Tips
- I like thick asparagus spears in this recipe. Count on about 3-4 thick ones per person, or 5ish thin ones per person, when buying the asparagus.
- Use good Parmesan cheese for this recipe – shave it off the block if possible, and grate a bit extra for a pretty garnish.
- Shallots look like small onions but they have a lovely, mild flavor. If you can’t find shallots, use a similar amount of sweet onion. Red, white, and yellow onions will be too strong for this dish.
- There’s a fair bit of dressing for this recipe, but if you’ve got over a pound of asparagus, double the dressing so it’s not too sparse.
- Lemons are all different – taste the dressing and add more lemon if it needs a bit more acidity. You want to taste the lemon in this dish.
What To Serve with Cold Asparagus Salad with Lemon and Parmesan

Frequently Asked Questions
No, this dish won’t be the same if you freeze it. Asparagus is one of the vegetables I never freeze or buy frozen – I can’t stand the limp, mushy spears when they’ve been thawed. Do this salad right, and the tender-crisp asparagus will make you convert, too!
It’ll keep fine for 2-3 days if tightly wrapped in the fridge. The dressing will keep for up to a week. You may see some discoloration on the asparagus from the dressing – this is fine, it is just the acidity of the lemon juice reacting with the asparagus. It’ll still taste fine.
Heck yes! Loaded with fiber and naturally low in carbs, this is a great pick on the keto diet. Plus, it’s so versatile – you can eat it for breakfast, lunch, or dinner!
