Can I use frozen asparagus instead of fresh?

Yes, frozen asparagus works, but it will be softer. Thaw and pat it dry before cooking to avoid excess water.

It is if you use margarine instead of butter, but check your margarine for milk solids. For strict dairy-free, use a plant-based butter alternative.

How do I make this dish nut-free despite the sesame seeds?

Sesame seeds are seeds, not nuts, so the recipe is naturally nut-free. However, if you have a seed allergy, you can omit them and simply dress the asparagus with lemon butter and herbs.

Ingredients: pound asparagus spears, ends trimmed; /3 cup margarine or butter; tablespoons sesame seeds; tablespoon lemon juice; tablespoon chopped fresh parsley; salt and pepper to taste

Ingredients

pound asparagus spears, ends trimmed
/3 cup margarine or butter
tablespoons sesame seeds
tablespoon lemon juice
tablespoon chopped fresh parsley
salt and pepper to taste

Instructions

Step 1

Start by snapping off the woody ends of the asparagus—they naturally break where the tender part begins. Fill a large pot with about an inch of water and add the spears. Bring to a rolling boil and cook just until the asparagus is fork-tender but still vibrant green. Thin spears may take only 4-5 minutes, while thicker ones need up to 7. Drain immediately and place on a serving platter. While the asparagus cooks, melt the butter in a small skillet over medium heat. Once melted, add the sesame seeds and stir frequently. Watch closely as they toast—they'll turn golden in about 2 minutes and release a nutty aroma. Take the skillet off the heat and mix in the lemon juice and fresh parsley. Season with a pinch of salt and pepper. Drizzle the buttery sesame sauce evenly over the asparagus. I find that serving this dish warm brings out the best in both the lemon and the toasted seeds.

Chef's Tip

For the brightest flavor, I always use fresh lemon juice and toast the sesame seeds until they're just golden—don't walk away, as they can burn quickly. A tiny pinch of red pepper flakes adds a gentle warmth if you like a little kick.

Storage Tips

Leftovers keep well in an airtight container in the refrigerator for up to 3 days. To reheat, I gently warm it in a skillet with a splash of water to loosen the sauce; it also tastes lovely chilled when tossed into a salad.

Variation Tips

For a nuttier twist, try swapping the sesame seeds for toasted slivered almonds or pine nuts. I sometimes add a clove of minced garlic to the butter for extra depth. This asparagus pairs wonderfully with grilled salmon, roasted chicken thighs, or even as a topping for a warm spinach salad. If you have leftover sauce, it makes a lovely drizzle for steamed broccoli or green beans.
