Roasted asparagus and mushrooms make the perfect combination
for a fresh, healthy spring dish.
So simple. So beautiful! And SO delicious!

The asparagus and mushrooms are first roasted in olive oil, then a little grass-fed butter is added for an extra dimension of flavor. Watercress is mixed in and the dish is finished off with a drizzle of aged balsamic vinegar.

The freshness of the asparagus complements the earthy mushrooms beautifully. The raw watercress adds a slightly peppery taste making the dish sublime.

This dish makes your body, mind and spirit feel good.  

Eating asparagus helps keep your blood sugar balanced.  They contain chromium, a trace mineral that enhances the ability of insulin to transport glucose from the bloodstream into cells.  Balanced blood sugar keeps your mood stable.


Mushrooms are a superfood. They contain a super powerful antioxidant called ergothioneine that’s only found in  mushrooms. They’re a good source of protein, fiber, B vitamins (especially niacin), vitamin C, calcium, minerals, and selenium.


In this recipe, I use oyster mushrooms which have anti-inflammatory benefits and strengthen your immune system. Oyster mushrooms are rich in many of the nutrients believed to enhance brain function.

Oyster mushrooms make the dish special and are commonly found growing wild in the spring.

The oyster mushroom is named for its shell-like appearance and resemblance to oysters. It’s very versatile with a mild flavor, woodsy aroma and silky texture.

If you can’t find oyster mushrooms, white button mushrooms or baby bella mushrooms will work, but won’t be as luxurious. Hen of the woods mushrooms are also great!

I’m a huge fan of quick and easy recipes that are super flavorful.  This is one of those dishes.  You simply prepare the mushrooms and asparagus, toss them in olive oil, season with salt, roast in the oven and let them cook. In the meantime, you can prepare salmon or whatever you like to go along with this dish.

I love when I can cook my main dish while my side dishes are cooking in the oven.

If your asparagus is thick, peel the bottom part and cut in half lengthwise.

Trim the stems off the mushrooms, they are quite tough. Leave the mushrooms in large pieces.

After about 15 minutes, add 1 tablespoon of grass fed butter and thyme leaves.  Organic grass-fed butter is good for you. Read about it here.

The butter coats the asparagus and mushrooms and gives them a light glaze.  But you can leave it out if you’re vegan. Add another tablespoon of extra virgin olive oil along with the thyme instead.

Once the vegetables are done, remove them from the oven and let cool for a few minutes.  Add the watercress and toss.

I’m always looking for ways to eat more watercress.

Watercress is one of the most nutrient-dense foods on the planet.  Last year, the Center for Disease Control put out a study that determined “powerhouse” fruits and vegetables—the ones most strongly associated with reducing the risk of chronic disease. Each food was given a Nutrient Density Score, the highest being 100, with higher-ranking foods providing more nutrients per calorie. Only one food was assigned a perfect score: watercress.

I love it because it has a peppery flavor, similar to arugula, but with a different—yet beautiful—shape, and a crispier texture.

Arrange the vegetables on a platter, top with a drizzle of balsamic vinegar and sprinkle with flaky sea salt.  The vivid greens and caramelized mushrooms make it so enjoyable.

Roasted Asparagus and Mushrooms is a great side dish. In addition, it’s an amazing party dish. It’s best served at room temperature and stays fresh for hours.  Serve it on Memorial Day or anytime you have guests this summer.

Definitely one of my favorites.
