Why you will love this dish
- Asparagus and leeks pair beautifully together, like in this Asparagus, Leek, and Brie Quiche.
- Brown butter is liquid gold. As the butter melts and slowly turns golden, brown bits form, creating a wonderful nutty flavor that elevates any dish.
- This dish works well with everything from chicken and pork to beef and shrimp.
Ingredient notes
- Pearl couscous - These tiny balls of pasta are made from semolina flour. They are quick-cooking and come in tricolor and traditional varieties. I used tricolor in this recipe.
- Asparagus - Fresh is best here. We're roasting it long enough to slightly caramelize it but not soften it completely.
- Leeks bring a very mild onion flavor that sweetens as they cook. Shallots can also be used.
- Thyme pairs wonderfully with leeks. Fresh thyme is great if you have it, but dried can also be used.
Step-by-step instructions
See the recipe card for complete instructions and ingredient amounts.
There are several steps in this recipe, but none of them are complicated.
Making couscous
- Cook the couscous according to the package directions. For added flavor, use chicken or vegetable stock in place of water.
- Fluff the couscous with a fork and transfer to a mixing bowl.
Roasting asparagus
- Cut off the tough root end of the asparagus. TIP: Bend a stalk of asparagus until it snaps. It will snap where the tough part ends. Use this piece as a guide for trimming the bottoms off of the remaining stalks.
- Cut the asparagus into 2-inch pieces. Transfer them to a parchment-lined sheet pan. Drizzle with oil and season with salt and pepper.
- Bake at 425 degrees for 8-10 minutes or until the asparagus reaches your desired tenderness.
- Grate Parmesan cheese - about 2 tablespoons - over the asparagus. Transfer the asparagus to the bowl with the couscous.
Cleaning leeks
Leeks tend to have a lot of grit and dirt between their layers, so cleaning them thoroughly is important.
- Trim off the root end and the dark green tops. Remove any tough outer leaves. Slice the leek in half lengthwise. Then, cut crosswise into ½-inch slices.
TIP: Save the root end and dark green leaves to make vegetable stock. Rinse to remove any dirt, dry, and freeze until ready to use.
- Add the leeks to a salad spinner. Submerge in water to rinse well.
- Drain and spin dry.
Cooking leeks
- Melt 2 tablespoons butter in a skillet over medium heat. Add the leeks and cook for 8-10 minutes until soft. Transfer them to the bowl with the couscous and asparagus.
Browning the butter
- Add 4 tablespoons of butter to the same skillet. Melt and cook until the butter turns golden brown. Brown bits will form at the bottom. These brown bits are flavor!
- Pour the brown butter over the couscous, asparagus, and leeks. Toss to combine. Top with grated Parmesan cheese and serve.
Serving and Storing

Leeks
- 1 large leek (or 2 small leeks)
- 2 tablespoons unsalted butter
- 1 teaspoon fresh thyme leaves
- ¼ teaspoon black pepper

Instructions
- Cook the couscous according to package directions. (Note 1) Fluff with a fork and transfer to a mixing bowl. Set aside.
Asparagus
- Preheat the oven to 425℉.
- Trim the tough end off of the asparagus and discard. Cut the asparagus spears into pieces 2 inches long. Transfer to a parchment-lined baking sheet. Drizzle with olive oil and season with salt and pepper.
- Bake for 8-10 minutes until the asparagus is slightly caramelized but still has some texture. Top with grated Parmesan and transfer the asparagus to the bowl with the couscous.
