Mushroom Quinoa Casserole

November 14, 2013

Casseroles remind me of old people. I feel like I’m not allowed to cook one unless I’m over the age of 80, decked out in a floral apron circa 1950. For the most part I love eating casseroles (more on that later), but I just feel like a sham when I’m cooking one. I’ve always wanted to do a behind the scenes of what food bloggers actually look like when they’re cooking. But sadly I think you would all be immensely disappointed by mine. I generally look like a train wreck when I’m cooking and that’s exactly how I like it. And I don’t do aprons. I just pretend that getting flour all over yourself is part of  “the art”. Sacrifices people.

It’s normal for a kid to beg their Mom to make mushroom barley casserole for Friday night dinner right? But then I went to university and the casserole was officially killed for me. When I was picking my residence for university I opted for a single room with a shitty cafeteria versus a shared room in a converted hotel with a chef. I know, a momentary lapse of foodie judgment. The food was by far the worst I have ever tasted with a new level of awful reached on Fridays.

Mushroom and Quinoa Casserole // thehealthymaven.com #glutenfree #veganFridays were “casserole days” aka everything from the week that they didn’t want going to waste mixed together and baked. I genuinely had no idea a TVP, pea, cous cous and mac and cheese casserole could even be considered a meal . Don’t get me wrong, I’m all for strange combinations, but they have to taste good. Let’s just say I experienced what I like to call the freshmen “negative 15”. So I was a bit weary to start tapping into the world of casseroles once more. But this Mushroom Quinoa Casserole definitely redeemed them for me. Now who’s going to help me recover from my casserole PTSD?

    Oh man, I feel like I could write a novel on the terrible-ness of college dorm food. It definitely ruined a lot of things for me. But this casserole is pretty much the total opposite of anything they served! So wholesome and yummy!

    Bahah casseroles remind me of old people too. I have ideas for a spaghetti squash casserole but keep putting it off for his very reason…you may have inspired me with this delicious looking creation though.

    Haha, I almost NEVER wear an apron either! And it’s a shame because I have a bunch of cute aprons hanging in my kitchen closet that never get used.

    Cafeteria food = gross. The one at my school was pretty icky. We had a pizzeria that wasn’t bad, though there was a whole lot of greasiness and artery-clogging food going on there!

      Ah a fellow apron virgin! I always seem to be wearing black when I’m baking though and get flour everywhere!

    My mom never, I mean never made us casseroles. So I feel very deprived of them. Needless to say, I want this casserole NOW. Thank you for sharing. A delicious end to a long Thursday! I hope you have a wonderful weekend!

    Family dinners aren’t complete without a good casserole in my family. Although, they usually aren’t as healthy as this one looks. The most common one in my family is called “funeral potato casserole”. It’s loaded with cheese, cream of chicken soup, and potatoes. Definitely not the healthiest but it is pretty dang good. Your recipe looks so good though! (I’m always a huge fan of quinoa)

    I grew up on casseroles and after having babies I realized why they were so great – mix them up and throw them in the oven and free time!!!

    What is it with casseroles getting a bad rep in general? I understand your antipathy after reading this post but for me casseroles/bakes have always been the epithome of comfort food and sit-down family meals. Unsurprisingly I’m still eating a lot of them even now that I’m living on my own.
    About your recipe: you know I don’t like quinoa, right? Yet vfor some this sound so good to me. Maybe because mushrooms make everything better? Well, I don’t have any quinoa on hand anymore in anyway right now … hm …
    Oh and don’t ask about the food at our cafeteria …It’d break every foodie’s heart.

      Hahahaha I have NO idea why some people have to ruin the casserole for everyone. Sometimes they can be so good and are super convenient.

      Did not know you didn’t like quinoa! Too bad 🙁 Might work with another grain though!

    I 100% feel you on the whole casserole thing! My grandma used to shove weird casserole concoctions down my throat when I was younger and I thought I was scarred ever since lol but lately I’ve been playing around with different recipes and this looks right up my alley! I’m on a huge quinoa kick so this is definitely going to be made soon! 🙂
