🥦 Ingredients

  • Mushrooms: 1 pound of mushrooms, any type will do (we used button in this recipe)
  • Asparagus: you’ll need about 1 bunch of asparagus, which is about 7-10 thin stalks

  • Salt and pepper: adds a dash of flavor

🥣 Recipe instructions (with step-by-step photos)

1️⃣ Step One: Prep oven and veggies

Preheat your oven to 400 degrees F (200 C). Wash and then dry the vegetables.

  1. To cut mushrooms: Wash mushrooms then slice into thin slices, though you could roast whole as well
  2. To cut asparagus: Remove the hard stems from asparagus by holding the asparagus stalk at the stem and the tip, and then breaking off the stalk from the hard bottom of the stem. Then cut into 1 inch pieces.

👉 Pro tip: Cut the asparagus into smaller pieces so it's both easier to eat with the small mushrooms, and also so both the asparagus and mushrooms cook at similar rate (smaller pieces of asparagus will generally cook faster than longer spears).

2️⃣ Step Two: Season and add to baking sheet

Place the asparagus and mushrooms on a baking sheet or roasting pan.

Toss the vegetables with olive oil until completely coated. Sprinkle garlic on top, then season with salt and pepper to taste.

3️⃣ Step Three: Bake asparagus and mushrooms

Roast the vegetables for 25 minutes or until just browned, making sure to stir the vegetables halfway through cooking time.

If the mushrooms are cooking faster than the asparagus, simply remove them to a plate and continue to cook the asparagus until it is browned.

Serve immediately, or let cool and save for later as a topping for salads or bowls.

Recipe questions + quick tips

How can I reduce prep time?

To minimize prep on cooking day, wash and cut the vegetables in advance. If you’re using mushrooms and asparagus as a topping for salads or bowls, bake the vegetables up to three days ahead of time.

How can I get my roasted vegetables to cook evenly?

Cut the asparagus and mushrooms into same-sized pieces to help them roast evenly. Also, separate the vegetables on the pan rather than mixing them together so you can remove one vegetable if it is cooking faster.


💡 Ideas for seasoning

We kept this recipe simple by using just garlic, salt, and pepper. For more variety, try some of these ideas:

  • Fresh or dried herbs: Try basil or Italian seasoning on your veggies.
  • Ginger or turmeric: These spices offer maximum flavor and a punch of color.
  • A sprinkle of cheesy flavor: Freshly grated Parmesan cheese will complement the garlic and veggies in this recipe. For a non-dairy option, try nutritional yeast or vegan Parmesan .

🧊 How to store leftovers

  1. Refrigerator storage: Store leftovers in an airtight container in the fridge. They will keep for up to 3-4 days. Reheat in the microwave or in a pan over medium heat on the stove.
  2. Freezer storage: Store leftovers in an airtight container or freezer-friendly bag for up to one month. Place in refrigerator for 24 hours to thaw, then reheat in a pan or place in the oven for 10-15 minutes to recrisp the vegetables.
