Tips for Prepping Vegetables
A few handy tips for working with your vegetables:
- Wash and dry the vegetables first.
- Secure your cutting board on the counter by laying a wet paper towel flatly underneath it.
- Always use a sharp knife! It’s safer, and a good, clean cut makes a big difference in the final presentation.
Expert Tips for This Recipe
- Use a large baking sheet pan, or in this case, two sheet pans.
- Use a hot oven, in this case 425 degrees
- Line the pans with natural parchment paper so nothing sticks. TIP: Foil doesn’t work as well!
- Make sure all of your ingredients are laying as flat as possible on the tray.
- Drizzle a little more olive oil (a teaspoon or two) over the vegetables when you remove them from the oven for turning.
- Turning the veg part way through the cooking time is easier with a sturdy, long spatula.
- If you can’t locate watermelon radishes or purple daikon radish, just use regular radishes instead.
- I use Maille Original Dijon Originale mustard, but any Dijon mustard will work.
- I swear by this Lemon Pepper Seasoning Blend with Grinder and use it any time a recipe calls for freshly ground pepper.
- I love to plate these roasted vegetables on a big, white serving platter. Drizzle just a little of the vinaigrette on the top, and serve the rest alongside.
- When plating, start with the asparagus on the bottom, then scatter the radish and fennel mixture over the top. Use the same process to plate it individually, too.
- This would make a great starter or side dish for grilled meats or fish, or as a side to this recipe for Summer Pasta. Try Roasted Nectarines with Caramel Sauce for a light and wonderful dessert!

- PREHEAT OVEN TO 425
- Line two large baking sheets with parchment paper
- FOR THE ASPARAGUS:
- Place the prepared asparagus on one of the lined baking sheets. Drizzle with 2 tablespoons of the olive oil, then sprinkle with a little salt and pepper. Set aside.
- FOR THE RADISH AND FENNEL:
- Combine the prepared radishes in a large bowl with the watermelon radish, purple daikon, fennel and shallots.
- Add the other 2 tablespoons of olive oil, or a little more if needed, and toss to completely coat the vegetables with the oil.
- Add a teaspoon of freshly ground pepper and 1 1/2 teaspoons of kosher or sea salt. Toss together to combine.
- Put the radish/fennel mixture on the second parchment-lined baking sheet, and spread the mixture out as evenly as possible for even roasting. Place the tray on the lower rack of the oven for 30 minutes. Remove from oven and gently turn the vegetables over with a spatula.
- Return the radish/fennel tray back to the oven on the lower rackNow put the baking sheet of asparagus in the oven too, on the middle middle oven rack – and roast both trays for about 15 minutes.
- Remove just the baking sheet with the radish/fennel mixture, and gently turn the mixture over once more with a spatula. This is to make sure the vegetables roast evenly. Sprinkle the radish/fennel mixture with the Parmesan cheese and a little more olive oil, then return the pan to the oven for another 10 minutes.Remove both trays from oven for serving.
- NOTE: The total roasting time is approximately 55 minutes for the radish/fennel mixture, but can vary depending on your oven. The vegetables are done when they are fork tender and a little blistered in appearance. Note that the total cooking time for the asparagus is about 20 minutes, which is why the cooking times are staggered so they come out of the oven at the same time.
- To Serve, transfer the asparagus to the serving tray or individual plates, then top with the radish and fennel mixture and a little more Parmesan cheese if you like. Use some of the fennel leaves for garnish, if desired. Serve with the vinaigrette alongside to drizzle over the top.
