    Cheezy Hashbrown Casserole

    Need a quick and tasty dinner idea? All you need are three simple ingredients and you can make my incredibly gooey, amazingly cheesy - Cheezy Hashbrown Casserole.

    Cheezy Hashbrown Casserole

    Ready for the EASIEST recipe ever?!

    All you need are 2 simple ingredients you should be able to find in any grocery store ..... and a batch of my cheese sauce.

    That's right - I'm using a bag of frozen veggies and a bag of hashbrowns. Mix them together in a bowl and stir in the cheese sauce.

    That's it! No spices, no added sodium, so added oil or fat, just pure cheezy, potato goodness.

    All you gotta do now is bake it.

    Since I'm making most of my recipes down here in the new BNV studio, I used my old Black n Decker Toaster Oven and even that worked fine.

    So no special appliances are needed, just an oven, and a blender to make the cheese sauce.

    If you are interested in the appliances I use - I'll throw some Amazon Links down below so you can check them out...so SPOILER ALERT, some Affiliate Links will be appearing and you know the drill... if you buy anything I make a little something something but at no extra cost to you...

    But you really don't need them. Like I said, a blender for the cheese sauce and an oven. Easy peasy.

    And get this - this week I even have the VIDEO ready for you too, so scroll down to watch exactly how easy this is to make.

    Ready? Here we go.

    Cheezy Hashbrown Casserole

    Cheezy Hashbrown Casserole | Brand New Vegan

    I used a bag of Simply Potatoes®, which are 12oz bags of prepackaged hashbrowns. They're in your grocery store's refrigerated section, so be sure and look there if you've never seen them before.

    There are some preservatives, but they are 100% oil-free.

    If you prefer, you can also use your favorite FROZEN hash browns instead but be sure and check the ingredients if you are avoiding added fats as I am.

    Simply dump these out into a bowl and grab your 2nd ingredient...

    A 12oz bag of frozen veggies. I used Broccoli and Cauliflower, but you can use whatever you like. Again, most of these bags of veggies are 100% oil-free but do check the ingredients. Some come in a sauce - and usually, that sauce has oil or other weird ingredients.

    Dump those in the bowl and mix them together.

    Go ahead - I'll wait.

    Did I tell you this was easy?

    Now add the cheese sauce.....oh wait! You gotta make some cheese sauce too!?!

    No worries - I can make a full batch of my Amazing Vegan Cheese Sauce using my IP method in 20 minutes flat. And.....truth be told.....I usually have some in my fridge anyway so it's always ready to go.

    Add 2 cups of the cheese sauce to the bowl and mix.

    Now spoon that into one of those glass casserole dishes and spread it evenly. I have a Pyrex® 2qt that is about 11" x 7" and that worked great.

    Pour on the rest of that cheese sauce and pop it into a pre-heated 400°F oven for about 20-30 minutes.

    Bam. Done.

    To clarify (because there are always questions), my cheese sauce makes about 4 cups. So 2 cups get stirred into the bowl and the remaining 2 cups go on top. I bake it uncovered too.

    Oh, one more thing for those of you who don't know me...my cheese sauce is ALSO made from potatoes. So for all you McDougall Mary's Mini folks....this is perfect and yes, I have been told my cheese sauce IS compliant.

    This is the PERFECT McDougall dish! I fill half my plate with this yummy casserole, and the other half with a salad or more veggies and it's the perfect lunch or dinner.

    That's it for this week. Hope you enjoy the recipe and if you do, leave those comments down below.

    Have a good week and I'll see you next Saturday.

      We have made this twice. First time we found it a bit bland. Second time we added 1 1/2 tsp salt, 1 1/2 tsp chili powder, 1/2 tsp liquid smoke, and 1/2 tsp seasoned salt. Used small frozen mixed veggies.
      Delicious! Thanks for this recipe and your site, Chuck!

      This is so quick and easy to make and everyone likes it. This is in our regular menu rotation for dinners and we probably have it at least once a month, particularly during the winter months. It freezes well, so it's easy to make a large quantity and have some in the freezer for a quick reheat on busy nights.

      One of the things I love about Chuck's recipes is that so many of them are super easy to put together. For me, this is one of those. It's quick, easy, delicious and, most importantly, healthy. This is a go-to in our household and is particularly good for busy nights. I often make this in advance (baked a casserole this morning), then separate it into freezer containers, and freeze it for future use. I love knowing I have a "backup" plan that still results in something tasty and plant-based. Thanks, Chuck, for all your work.

      Hi Chuck,
      First of all, I love many of your recipes. I am looking for a clarification on this recipe. In the top section telling us how you do it it mentions a 12 ounce bag of hashbrowns. In the ingredient list, it says 20 ounce. How much grated potatoes are we to use? Thanks.

      Hi Chuck, could i make the hash browns by chopping or grating potatoes? I've never seen frozen hash browns here in Australia.

      I found oil free dehydrated shredded potatoes on Amazon and this was delicious with a bag a Japanese veg mix. Perfect for day 5 of my Mary's Mini. So good!

      Finally made this wonderful casserole. Delicious. My husband from Minnesota loves 'hot dishes'... this one is A BIG KEEPER! The cheese sauce is fantastic. I have about 6 different recipes for plant based cheese sauce, this and one other are my go to's. Thank you again for nummy recipes and inspiration!

      Oil free hash browns are not available where I live. Can you use fresh grated potatoes?

      Another great and easy template recipe. I made a cauliflower bechamel with some cajun spice and added a can of mushrooms and managed to eat half of it in one sitting. Oops.

      The pictures looked so yummy I had to make it right away! I used frozen oil free hash browns and some frozen cauliflower florets and about 1 cup of frozen corn I had on hand. Instead of BNV cheese sauce I used Jill McKeever's oatmeal based game changer sauce because I already had some in the fridge. I tossed some stale-ish sourdough bread in the food processor until I had fine breadcrumbs that I put on top of the cheese sauce -- they toasted nicely and gave some extra texture. We devoured the casserole before having a chance to snap a picture. This one is easy and really, really good.

      Great, easy recipe. Totally tastes like you’re cheating. SO many possibilities with this one. Next time I may add a can of green chili’s. Thanks!
