Keto Breakfast Casseroles 


1. Keto Tater Tot Casserole Recipe

By Fit Mom Journey

I don’t know about you, but I love tater tots. The little salty, golden, crunchy goodness has always been my favorite breakfast item. Growing up, I ate tater tots as breakfast and snacks. And now as an adult, my favorite way of eating them is in casserole. 

Conventionally, tater tot casserole is not keto, but I lean on Fit Mom Journey’s recipe for the keto twist. Gretchen, there is a true expert in making your favorite dishes low-carb and keto, and this one is my top pick. 

With just a handful of ingredients you have in hand, she made it easy to have a dinner ready quick. And it’s really easy to sub the ground meat with rotisserie chicken! I also like to mix this recipe up and change up cheese and whatnot.

If you are using this recipe as part of your meal prep, feel free to throw this in the freezer for future use. I also like to bake up this casserole dish and pack them up per serving for lunch on the go. 

Granted, it has no actual tater tot in this keto casserole, but it has enough flavors of the meal you loved as a kid. 

If you are ready, head on over to this keto tater tot casserole recipe to whip up this crazy good dish! 

2. Keto Almond Flour Biscuit Casserole Recipe

Keto Almond Flour Biscuit Casserole Recipe
By Ruled.me

I once lived in South Carolina for a brief year, and this recipe reminds me of the dishes I had there. 

It’s my southern dish made into keto. The almond flour biscuit adds warmth to this dish and makes you forget you are on a weight loss diet. 

It’s also not lacking in flavors. It’s full of it. It’s got the hot, spiciness from the sausages and creaminess from the sauce. It’s one keto breakfast meal you want to wake up to on a Christmas morning. If you don’t tell your guests, they won’t even suspect it’s keto. 

To make this ahead, I suggest you keep the biscuit separate from the rest. When it’s ready to put in the oven, you add a layer of the keto biscuit on top and bake till it’s golden. 

It’s an awesome keto breakfast casserole anyone can make and everyone will love. 

Ruled.me is awesome as showing the recipe step-by-step. Even if you are not a regular cook, you can make this in a snap. It pretty fails proof and the nutrition info is also there. 

3. Keto Egg Casserole Recipe

By Wholesome Yum

If you are looking for a keto holiday brunch idea or low-carb breakfast, look no further. 

This keto egg casserole recipe is an awesome way to have your breakfast made ahead. As a lazy cook myself, I also love that I can pack it for work and take it to go with a breeze. And as you’d guessed it, I wouldn’t hesitate packing this into my kiddo’s lunch box. 

It’s one yummy low-carb casserole dish that goes a long way once it’s made and out of the oven. Wholesome Yum makes this dish with sausage, egg, and cheese, but I’d throw in whatever I have in the fridge. 

If I have frozen spinach left in the freezer, I’d throw it in. And I’m also pretty open with the type of cheese I use. I have used cheddar cheese since that’s what I usually have. But if that’s low in stock, I’d add in Swiss without hesitation. 

And no sausage? No problem. I can see cubed ham, bacon, and even meatless options go really well here. 

One thing about this recipe is that if you decide to make ahead or use it part of meal prep, go ahead and bake it first. From there, you can cut them in bite-size pieces to save for later. 

Keto Lunch and Dinner Casseroles 

4. Keto Chicken Mexican Casserole Recipe 

Keto Chicken Mexican Casserole
By Joy Filled Eats

One cuisine I’ve always loved is Mexican. I love everything from tacos to low-carb enchiladas. But eating keto means you need some adjustments and at times a bit of sacrifice. 

But a recipe like this one from Joy Filled Eats makes me completely forget I’m on keto, let alone on diet. 

It’s a huge win-win in my book. 

And what I love about this recipe is that you can even use the filling in a low-carb tortilla. For work lunch, I’d serve it on top of cauliflower rice. As a casserole, wrap, or on cauliflower rice, it’s equally delicious and flavorful. 

I’m also impressed that it only takes 5 ingredients. And yes, you can use your on-sale rotisserie chicken for this recipe. It’ll save you money and time. I actually never tried freezing this keto chicken casserole, but I imagine you can. I usually end up baking it right away for immediate pleasure! 

Got some sour cream in the fridge? Drop a scoop when serving. 

5. Keto Turkey Thanksgiving Casserole Recipe

Keto Turkey Thanksgiving Recipe
By That Low Carb Life

I love Thanksgiving dinner and all the side dishes and all. But one thing I don’t look forward to is eating the same thing for what seems like an eternity. 

My go-to has always been turkey sandwich, and it’s boring. 

So I started looking for other creative ways to use my leftover Thanksgiving turkey. And I came across this. Low-carb keto Thanksgiving casserole recipe

What I love the most about this recipe is simplicity. And that’s crucial ’cause who wants to do any more cooking after the big day. 

I certainly don’t want to, and this recipe is hardly any work. 

It uses all the same ingredients you have from the Thanksgiving feast, so you don’t need to go shopping. All you have to do is to mix everything in one bowl and pour it into the baking dish. Put it in the oven and enjoy it when it’s done. 

And I’m not oversimplifying! It’s really that easy and it’s also amazingly delicious. 

If you don’t want to eat another turkey meal after Turkey Day, put it in the freezer for an emergency dinner. 

You’ll be glad you had it there.

Oh, by the way, you can sub this with chicken too if you don’t have any turkey left.

The Seasoned Mom

This zucchini casserole dish is the perfect recipe to serve your family a.k.a. picky eaters. 

It’s crunchy, cheesy, and feels a bit more elevated with Parmesan. 

When it’s in the oven, it smells amazing and brings the whole family together. 

It’s the type of dinner I crave after a long hectic day. 

This recipe, in particular, is not necessarily designed for keto, but it’s a low-carb recipe. For keto, you just need to omit the breadcrumbs and opt-in on crushed pork rinds. 

The rest should find the way it is.
