Mustard and Mayonnaise Glazed Asparagus (Grilled)

There’s something about the char of a grill that awakens flavors like nothing else can, and asparagus is no exception. I remember one sweltering summer evening, a community barbecue hosted by my eccentric Aunt Millie. She always insisted on grilling everything, even things you wouldn’t expect. That year, she unveiled asparagus slathered in a creamy, tangy concoction. I was skeptical, to say the least, but one bite banished all doubts. The smoky, blistered exterior gave way to tender, flavorful spears. It was a revelation, and I’ve been experimenting with grilled asparagus ever since. This recipe, with its vibrant mustard and mayonnaise glaze, captures that same unexpected magic.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 6 minutes
• Total Time: 36 minutes
• Servings: 6
• Dietary Type: Gluten-Free

Ingredients

• ¼ cup mayonnaise
• ¼ cup grainy mustard
• ¼ cup extra-virgin olive oil
• 3 tablespoons fresh lemon juice
• 1 teaspoon finely grated lemon zest
• 1 garlic clove, crushed
• 2 teaspoons kosher salt
• 2 teaspoons fresh ground black pepper
• 1 lb thick asparagus, trimmed

Equipment Needed

• Shallow dish
• Whisk
• Grill

Instructions

1. In a shallow dish, whisk together the mayonnaise, grainy mustard, extra-virgin olive oil, fresh lemon juice, finely grated lemon zest, crushed garlic clove, kosher salt, and fresh ground black pepper. Ensure the mixture is well combined, creating a smooth and emulsified glaze.
2. Add the trimmed asparagus to the shallow dish. Turn the asparagus spears to thoroughly coat them in the mustard and mayonnaise glaze. Make sure each spear is evenly covered to ensure consistent flavor and blistering on the grill.
3. Let the coated asparagus stand at room temperature for 30 minutes. This allows the flavors of the marinade to penetrate the asparagus, resulting in a more flavorful and tender final product. It also helps the marinade adhere to the asparagus during grilling.
4. Preheat your grill to moderately high heat. A well-heated grill is crucial for achieving the desired char and blistered texture on the asparagus.
5. Grill the asparagus over moderately high heat, turning occasionally, until the spears are tender and lightly blistered in spots, about 6 minutes. The grilling time may vary slightly depending on the thickness of the asparagus and the heat of your grill. Keep a close eye on them to prevent burning.
6. Serve the grilled asparagus hot or at room temperature. This dish is versatile and can be enjoyed immediately or prepared ahead of time.

Expert Tips & Tricks

• For an extra layer of flavor, try adding a pinch of red pepper flakes to the marinade for a subtle kick.
• If you don’t have grainy mustard on hand, Dijon mustard makes a suitable substitute.
• To prevent the asparagus from sticking to the grill, lightly oil the grates before grilling.
• Don’t overcrowd the grill. Grill the asparagus in batches if necessary to ensure even cooking and browning.
• If your asparagus is very thick, you can blanch it briefly in boiling water for 1-2 minutes before grilling to help it cook through. Just be sure to pat it dry before adding it to the marinade.
• Leftover marinade can be used as a flavorful salad dressing or as a dipping sauce for other grilled vegetables.
• To get even more char, don’t move the asparagus too often. Let it sit in one spot on the grill for a minute or two before rotating.

Serving & Storage Suggestions

This mustard and mayonnaise glazed asparagus is a fantastic side dish for grilled chicken, fish, or steak. It also pairs well with roasted vegetables or a simple green salad.

Store any leftover grilled asparagus in an airtight container in the refrigerator for up to 3 days. To reheat, you can microwave it briefly, but grilling it again for a minute or two will restore some of the original char and texture. It can also be eaten cold, straight from the fridge.

FAQs (Frequently Asked Questions)

Q: Can I use thin asparagus for this recipe?
A: While thick asparagus is preferred because it holds up better on the grill and has a more substantial texture, you can use thin asparagus. Reduce the grilling time accordingly to prevent it from becoming overcooked.

Q: Can I make the marinade ahead of time?
A: Yes, the marinade can be made up to 24 hours in advance and stored in the refrigerator. This allows the flavors to meld together even more.

Q: What if I don’t have a grill?
A: You can roast the asparagus in the oven at 400°F (200°C) for about 10-12 minutes, or until tender and slightly browned.

Q: The marinade seems very lemony. Can I reduce the amount of lemon juice?
A: Yes, if you prefer a less pronounced lemon flavor, reduce the lemon juice to 2 tablespoons.

Q: How do I know when the asparagus is done?
A: The asparagus should be tender but still slightly crisp. It should also have some char marks on the outside. You can test for doneness by piercing a spear with a fork; it should be easily pierced but not mushy.
