Pretty much my entire family is originally from a three town radius. We would trick-or-treat at my aunts and uncles houses, had a massive table for Thanksgiving, and Christmas was two days of different combinations of family members gathering at different houses, and even welcoming those that were as far-flung as, you know, the next county. Obviously as the generations have grown up and families have expanded and moved around, these holiday celebrations have changed, but one of the biggest changes for me as a kid was when my aunt, uncle and cousins moved to Kentucky. Since we all grew up together, spending most of our days at each others’ houses or going on outings or vacations together, Kentucky felt like it was pretty much halfway across the world.

One thing we could count on, though, was that they did come back to New Jersey for Christmas as often as they could. And they always stayed at our house. Now, our house was by no means small, but it wasn’t huge either. So when it expanded from four people living there to nine, plus a Christmas tree and presents and the dining room table with the extra leaf in it and more family members popping in and out, well, it did feel sometimes like it was busting at its seams. We were always thrilled to see each other, but, you guys, between the bath towels and the food. Well, just wow.

So it was always good to find some meals that could feed a crown for not a long of money. So we always made one (or two) of those big ol’ breakfast casseroles where you let the bread soak in the egg and cheese mixture overnight, then bake it in the morning. It was easy, filling, and reheated well a couple days later.

Well, naturally I had to remake it with my favorite sneaky veggie…

You guessed it – cauliflower!

Cauliflower Hash Browns Slow Cooker Breakfast Casserole is such a simple way to make a morning meal for a big crowd.

Plus, you’ll be starting the day off with a big serving of vegetables and tons of protein.

And eggs are one of the most economical sources of protein. I threw in some pre-cooked breakfast sausage, but if you want to save a few more dollars or are serving vegetarians, you could leave it out. Other alternatives would be bacon, vegetarian sausage crumbles, or even bits of leftover Christmas ham, to really be frugal.

My version is also gluten free, low carb, and, if possible, even easier than the original version, since the slow cooker does the work. It’s ready as soon as you wake up… no waiting for it to bake for forty-five minutes.

Or, you know, everyone loves breakfast for dinner, so this slow cooker breakfast casserole is a perfect meal to come home to on a busy weeknight. The boys and I put a major dent in this, and they had some more for lunch a couple days later. I am actually freezing the rest of it, since it made so much! Honestly, I’ll probably cut down or skip the onion entirely next time, since I’m not a huge onion gal. but I know a lot of people like them, so I left them in.

Do what makes you happy. Sometimes the best budget friendly ingredient is versatility.

An easy recipe to feed a crowd!

Ingredients

  • 12 eggs
  • ½ cup milk
  • ½ teaspoon dry mustard
  • 1 teaspoon kosher salt
  • ½ teaspoon pepper
  • 1 head cauliflower shredded
  • additional salt and pepper to season the layers
  • up to one small onion diced (can omit or use less)
  • two 5 oz packages pre-cooked breakfast sausages sliced (I used turkey sausage. Can also omit, or use about 1 lb bulk breakfast sausage cooked and crumbled, or bacon, vegetarian sausage crumbles, or chopped ham)
  • 8 oz. or about 2 cups shredded cheddar cheese

Instructions

  • Grease or coat a 6 quart slow cooker with cooking spray.
  • Lightly beat together the eggs, milk, dry mustard, salt, and pepper.
  • Place about a third of the shredded cauliflower in an even layer in the bottom of the slow cooker, and top with about a third of the onion. Season with salt and pepper, the top with about a third of the sausage and a third of the cheese. Repeat the layers two more times.
  • Pour the egg mixture over the contents of the slow cooker.
  • Cook on low for 5-7 hours, or until eggs are set and the top is browned.

Enjoy!

          Hi Joni,
          This is a slow cooker recipe, so I’m not certain how long it would take to bake in an oven. I would think 350 degrees F. should be fine, but I’m sorry… I have no idea on the time.

          1. Joni

            For the oven, I tried 375 degrees for 20mins, then realized the edges were browning too quickly, so lowered to 350 degrees for another 25mins. – I need more patience & bake longer at 350 like you recommend! 🙂 This is a wonderful recipe & your reheating through pan frying is perfect!

      Hi Lindsey, I do not have the nutritional information, because it varies depending on the ingredients used. There’s a free nutritional calculator on myfitnesspal.com that you can use to calculate the nutrition, though!

    Hey there! Awesome recipe. Got it in my crock pot now! Question: it’s almost done but is SUPER watery. You’re recipe doesn’t mention cooking the cauliflower first. Was I supposed to?

      Lauren, I’m sorry that I didn’t see your comment until this morning.
      No, you do not cook the cauliflower first. I’m not sure why the hash browns were watery when you made them, but I suppose moisture content could vary based on the size of the cauliflower. Next time you make it, perhaps try keeping it on low, with the lid off for a short time near the end of the cooking time. This may allow some moisture that naturally builds up in the slow cooker to evaporate.

  2. Looks yummy. I had a couple of questions though.
    I am always confused when people say a head of cauliflower. Are we talking a small or large head of cauliflower? Do you know how much it would make when measured out?
    What is the best way to shred cauliflower?
    And okay, one more question, can heavy whipping cream be substituted for the milk?

    1. I have not tried heavy cream. I would be a bit concerned about it cooking so long in the slow cooker. As far as shredding, I personally like to use the shredder blade for my food processor, but you can do it by hand on a cheese grater. I have seem some really large heads of cauliflower lately in one of the grocery stores near me, and that would probably end up with too much. I’d say a “medium” head ends up with about 6 cups, give or take a little.

  3. So I’m curious – do your kids know it’s cauliflower? This sounds like something my mom would have made us when we were kids, but we were so picky she probably would have “forgotten” to mention it wasn’t actual potatoes, lol!

    This looks wonderful, and I love that it’s in the slow cooker – so much easier if you have a holiday crowd at your house!

  4. My husband has a huge family…so I can picture the full house you described! This dish sound delicious, and something I would consider even making during the week for “breakfast for dinner”.

  5. Linda | Brunch with Joy

    Yum! This looks sooo delicious and sneaking in veggies sounds like a brilliant idea. Gonna try this one of these days.

  6. 5 stars
    Saw this on Twitter and had to come for the recipe. I’m glad I did: what a great slow cooker breakfast idea! We are vegetarian and I think I would maybe sub in sauteed mushrooms for the sausages. Will pin and Stumble when on less awkward device.
