Can I make this recipe ahead of time?

Yes, you can roast the asparagus and radishes in advance and store them in an airtight container in the fridge for up to 3 days. Reheat in a skillet or a 350°F oven for best texture. However, add the mustard vinaigrette just before serving for maximum freshness.

What type of mustard works best in the vinaigrette?

Whole grain mustard gives the vinaigrette texture and a bold, tangy punch. If you prefer a smoother dressing, you can substitute with Dijon mustard or even spicy brown mustard, depending on your taste preferences.

Can I use frozen vegetables instead of fresh?

Fresh asparagus and radishes are best for this recipe, especially for optimal roasting texture. Frozen vegetables may release too much moisture and become soggy. If using frozen, make sure they are fully thawed and patted dry before roasting.

Is this dish suitable for special diets?

Absolutely. It’s naturally gluten-free, dairy-free, vegan, and low-carb. You can easily adapt the recipe to suit keto, paleo, or Whole30 diets by checking that your mustard and vinegar are compliant with your plan.
