How to Make Roasted Asparagus and Radishes with Mustard Vinaigrette
Step 1: Preheat Your Oven
First things first! Preheat your oven to 400°F (200°C). A hot oven is essential for getting those delicious caramelized edges on your veggies.
Step 2: Prepare the Vegetables
Place your trimmed asparagus and halved radishes on a baking sheet. Drizzle them with 2 tablespoons of olive oil, then season generously with salt and pepper. Toss everything together so that each piece gets nicely coated. This step ensures even roasting!

Pop the baking sheet into your preheated oven. Roast for about 20–25 minutes, turning once halfway through. You want those veggies tender but still with a bit of bite—plus that lovely golden color!
Step 4: Whisk Together Your Vinaigrette
While your vegetables are roasting, grab a bowl! Whisk together whole grain mustard, Dijon mustard, red apple vinegar, minced garlic, olive oil, and honey (if using). Mixing these ingredients creates an emulsion that coats the veggies beautifully.
Step 5: Final Seasoning
Taste your vinaigrette! Add salt and black pepper as needed. Adjusting seasoning at this stage makes sure every bite bursts with flavor.
Step 6: Assemble Your Dish
Once your roasted asparagus and radishes are ready, arrange them artfully on a platter. Drizzle your homemade mustard vinaigrette over the top—this not only enhances flavor but makes it look gorgeous!
