Roasted Asparagus and Mushrooms

Oven-roasted asparagus and mushrooms are the best spring side dish ever. It is easy, quick, and delicious. The best thing that can ever happen to asparagus is to roast them in the oven or grill them outside. They have such an amazing taste, you really don't even need much seasoning. This recipe will give you a one-sheet pan, no-mess dish that is suitable for most diets including low-carb, vegan, paleo, keto, dairy-free, and gluten-free.

Prepare asparagus before roasting

  • Rinse them. 
  • Snap them. Where they break, they break. You can't really snap them at the wrong place. They break where the asparagus gets woody and hard. Discard the bottom or use them in veggie stock.
  • Peel the ends if needed. If the end of the asparagus is still thick after snapping, you can peel the bottom inch or two with a vegetable peeler.

Roasting asparagus and mushrooms

  • Line your baking sheet with parchment paper and spread the prepared asparagus in a single layer. 
  • Drizzle with 1 Tbsp olive oil, salt, pepper, garlic powder, and nutritional yeast.
  • Wash and mix mushrooms with 1 Tbsp olive oil, salt, and pepper in a separate bowl and arrange them in between the asparagus.
  • Roast them in the oven on 425 Fahrenheit (220 degrees Celsius) for 13-15 minutes depending on the size of the mushrooms and the thickness of the asparagus. Both the asparagus and the mushrooms should be tender if you pierce them with a fork and lightly brownish.



  • We always wash the dirt off the mushrooms.
  • If the mushrooms are small enough, you can roast them whole.
  • Mushrooms have a lot of moisture, so we recommend using a fan oven. If you don't have one, open the oven time to time or place a wooden spatula behind the door to keep it slightly open for the entire time. This way the moisture that turns into steam will leave the oven and the asparagus will roast and not cook.
  • If you find any part of the asparagus not worth roasting, you can always use them to make veggie stock.
  • I have a little trick to keep them from drying: If it is the end of the season or the asparagus are already woody and wrinkly, after preparing them as per instructions I usually drop them in a bowl of cold water. I store them in the water and in the fridge. I found that if I don’t store them in water, then they snap closer to the spear, so I lose a larger portion of the stalk. In this way, the drying stops, but you have to use them within 2 days tops.
