Recipe Information
Ingredients
- 1 lb asparagus
- 8 oz mushrooms (baby bella or white button)
- 1 medium red onion
- 2 tbsp olive oil
- 1 tsp garlic powder
- 0.5 tsp dried thyme
- 0.75 tsp kosher salt
- 0.5 tsp black pepper
- 1 small lemon (optional, for serving)
Instructions
Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
Wash and trim the woody ends of the asparagus. Cut the asparagus into 2-inch pieces and place them in a large mixing bowl.
Clean the mushrooms with a damp paper towel, remove the stems if necessary, and cut them into halves or quarters depending on size. Add to the bowl with the asparagus.
Peel and slice the red onion into 1/4-inch-thick wedges. Separate the onion layers slightly and add them to the mixing bowl.
Drizzle the vegetables with olive oil and sprinkle with garlic powder, dried thyme, kosher salt, and black pepper. Toss everything together to ensure the vegetables are evenly coated with oil and seasonings.
Spread the vegetables in an even layer on the prepared baking sheet, ensuring they are not overcrowded.
Roast in the preheated oven for 18-20 minutes, stirring halfway through, until the asparagus is tender and the mushrooms and onions are lightly caramelized.
Remove the roasted vegetables from the oven and transfer to a serving platter. Optionally, squeeze fresh lemon juice over the top for a bright, zesty finish.
Serve warm as a side dish and enjoy!
