What better way to welcome Spring than with shades of purple, pink, and red from fresh radishes! Maybe you’ve picked some up from the market, or picked them from your garden and are looking for a new and exciting way to eat them. And this recipe is it.

If you don’t love the sharp, peppery bite of raw radishes, roasting them is the answer, a technique that mellows them out and brings out their natural sweetness. Then they’re elevated in probably one of the easiest, most delicious lifts ever: showering them with a cheesy, salty, nutty topping made from nutritional yeast, chopped walnuts, and fresh basil (or parsley).

I nearly ate the whole plate in one sitting. Such a good blend of flavors and textures that make a person love eating vegetables.

Tender, mild radishes with umami packed nutritional yeast, (one of my favorite ingredients that’s often overlooked!) is a match made in heaven.

And if you’re looking for another tasty way to use nutritional yeast, try my 5-Minute Vegan Salad Dressing.

What Do Roasted Radishes Taste Like?

You may not like raw radishes because they can have a spicy bite. But roasting radishes may change your mind about them, transforming them into something more tender, mellow, and almost sweet.

They’re absolutely delicious. And a great side dish in the spring and summer months for Rotisserie Chicken on the Grill and Marinara Baked Eggplant.

How To Roast Radishes:

  1. If your radishes have the greens attached, cut them off right at where the radish begins. (You can save radish greens and saute them!) Wash radishes thoroughly to remove dirt.
  2. Depending on how big your radishes are, cut them in half or quarters, vertically.
  3. Toss with olive oil and salt. Place cut side down on parchment lined baking sheet. This will help them brown.
  4. Roast for 15 to 19 minutes at 450 degrees F, until radishes are fork tender. Enjoy on their own or with the yummy walnut and nutritional yeast crumble in this recipe.

How Long to Roast Radishes:

If you’re looking for a quick cooking vegetable, radishes are a superb choice because they have very thin skin and a good amount of water. They like high heat; 450 degrees F, and are done in about 15-20 minutes depending on how large your radishes are.
