Vegan Creamy Mushroom Quinoa Casserole

September 17, 2010 by Keri

A casserole can be a beautiful thing.  You take what’s in the refrigerator or pantry, get a little creative, and end up with a full meal baked into a single dish.  Plus, casserole leftovers are always the best!  Once all those flavors get a chance to combine, it’s perfection.  This vegan casserole has a little of everything- quinoa, eggplant, onion, broccoli, peas, corn-  in a creamy mushroom sauce and topped with panko bread crumbs.

Vegan Baking Recipes


  • 1 cup quinoa
  • 2 cups vegetable broth
  • 1 medium eggplant, sliced into 1-inch cubes
  • 1/2 white or yellow onion, sliced
  • 2 teaspoons olive oil
  • 1 teaspoon sea salt, divided
  • 2 cups frozen broccoli, thawed and drained
  • 1 cup frozen peas, thawed and drained
  • 1 cup frozen yellow corn kernels, thawed and drained
  • 32 ounces vegan cream of mushroom soup
  • 3 tablespoons Marsala
  • 4 cloves garlic, minced
  • 1/2 teaspoon black pepper
  • 2 cups panko bread crumbs

Preheat oven to 425 degrees.  Toss eggplant and onion with olive oil and 1/2 teaspoon sea salt and roast for 12 minutes or until eggplant is tender.  In a small pot, bring vegetable broth and quinoa to a boil, reduce heat to low, and cook covered for 12 minutes or per package directions.  Remove from heat and fluff with a fork.  In a separate bowl, combine cream of mushroom soup, marsala, garlic, black pepper, and 1/2 teaspoon sea salt.  To assemble casserole, transfer quinoa to the bottom of a 2.5 quart casserole dish, layering broccoli, peas, and corn over the top.  Next layer in the roasted eggplant and onion.  Pour mushroom soup mixture evenly over the top of the eggplant and onion layer.  Finish by spreading panko bread crumbs evenly over the top.  Reduce oven temperature to 350 degrees and bake for 35 minutes.  Panko will be golden brown.  Enjoy!

      Thanks Noelle for your comment. I’ve been wondering why I’ve lost my creativity but reading your comment made me realize it is because of the hectic schedule lately. Thanks for the insight.

    I loved casserole as a kid because it hid the taste of the vegetables, LOL!

  5. I was wondering how you were going to pull off a creamy vegan casserole– I had no idea they made vegan cream of mushroom soup!!! I need to track this down asap!!

    My son can’t have eggplant. Would zucchini work?

    I love the Imagine soups. I get mine at Whole Foods Market but I think I’ve seen them at Ralph’s (Kroger’s) in the health food section along with the Amy’s soups.

    anyone tried it ? id love to see reviews… im thinking of doing it this weekend but i’m a bit scared cause im the only vegan in the house and im afraid it would just not please the omnivores since they are picky eaters….
    Thank You!

    I tried it tonight and let me say it came out to be more than great.
    I pimped it out to meet my style though: i eliminated the peas, and instead i did a layer of creamy corn (2 reg. sized cans), and in the eggplant layer i added 3 zucchinis, finally instead of putting cream of mushroom soup ( i couldn’t find that) I used Butternut squash soup from the same brand to replace it.
    It was delicious. And let me say, a small piece of that casserole loads your stomach! I got food now for at least 3 days! (Awesome for exam periods like now 🙂 ) It’s cheap, very easy to make and delicious!
    Thank you for sharing this with us!
