Every spring I get a bit obsessed with Asparagus Recipes, and if you’re also an asparagus fan you might want to click that link and see all the great options I have for cooking asparagus. And for people who also love mushrooms, it doesn’t get much better than this recipe for Roasted Asparagus and Mushrooms! I used my favorite Spike Seasoning to season the asparagus and mushrooms before I roasted them.

Then when the asparagus and mushrooms were perfectly roasted, I sprinkled on some Trader Joe’s Everything-but the-Bagel Sesame Seasoning Blend. Some people claim it’s called “Everything” seasoning because it tastes good on everything, but I’m not sure about that. But I do know that it was amazing on the Roasted Asparagus and Mushrooms!

And I think roasted vegetables like this are the perfect side dish, and this combination is not only easy to throw together, but it’s also so fabulous tasting you could serve it for your fanciest dinner party with no apologies.

Roasted Asparagus and Mushrooms (with Everything Bagel Seasoning)

Prep Time 15 minutes
Cook Time 20 minutes
Total Time 35 minutes

Roasted Asparagus and Mushrooms is a delicious side dish option, and I used the now-famous "Everything" Bagel Seasoning to bump up the flavor here!

Ingredients

  • 1 lb mushrooms, washed, dried, and cut in quarters (see notes)
  • 1 lb. asparagus, trimmed and cut in diagonal pieces 1-2 inches long
  • 2 T olive oil
  • 1 tsp. Spike Seasoning (optional, but good.)
  • fresh ground black pepper to taste
  • 1-2 T Everything Bagel Seasoning (Use more or less to taste)
  • sea salt to taste for seasoning finished dish

Instructions

  1. Preheat oven to 400F/200C. Spray a baking sheet with non-stick spray or brush very lightly with olive oil.
  2. Rinse mushrooms with cold water and let them drain well in a colander placed in the sink.
  3. Snap one piece of asparagus to see where the woody part starts, then trim all the asparagus to that length. Cut asparagus on the diagonal into 1-2 inch pieces.
  4. Pat mushrooms dry with paper towels if they still seem wet, then cut mushrooms into fourths.
  5. Put asparagus and mushrooms into a large plastic bowl. Drizzle olive oil over vegetables, then sprinkle with Spike Seasoning (affiliate link) and pepper. Stir so all vegetables are evenly coated with olive oil and spices.
  6. Arrange the asparagus and mushrooms in a single layer on roasting pan. Roast until all the liquid from the mushrooms has evaporated and asparagus and mushrooms are slightly softened and starting to brown; about 20 minutes total cooking time. (I would start checking after 15 minutes.)
  7. Sprinkle cooked vegetable with desired amount of Everything Bagel Seasoning (affiliate link) and a little sea salt and serve immediately.

Notes

I used brown Cremini mushrooms but you could use any type you like.
