Benefits of Grilling Asparagus in Foil

You’ll find that asparagus remains crisp and vibrant. For example, grilling with olive oil and herbs infuses the vegetables with rich flavors while preserving their nutritional value.
Ease of Preparation and Cleanup

Preparing Asparagus for Grilling
Preparing asparagus for grilling requires simple steps to enhance its natural flavor and ensure perfect texture. Follow these guidelines for optimal results.
Selecting the Right Asparagus
- Choose bright green asparagus spears. Look for firm stalks with tightly closed tips.
- Avoid spears that are limp or pitted. These indicate age and may have less flavor.
- Consider the thickness of the spears. Thicker ones stand up better to grilling without overcooking while thinner spears become tender quickly.
- Purchase asparagus that feels cool to the touch. Freshness plays a crucial role in taste and texture.
- Drizzle olive oil over the asparagus for richness. It helps in achieving a perfect char and enhances flavor.
- Sprinkle sea salt for basic seasoning. Salt draws out moisture and enhances the asparagus’ natural sweetness.
- Add minced garlic for added depth. Garlic pairs well with the smoky flavors from grilling.
- Mix in lemon zest or juice to brighten the dish. The acidity balances the richness of the oil.
- Consider fresh herbs, such as thyme or rosemary, for an aromatic touch. Herbs infuse the asparagus with additional flavor during grilling.
