This Paleo and Whole30 Mexican Breakfast Casserole has a sweet potato crust and is packed with sausage, peppers and onions plus the perfect spices for an anytime-recipe that everyone will love – even kids! Great to make ahead of time, too.
There is nothing I love more in the morning than realizing that breakfast is already made. For real, NOTHING. There was a time, way back when, when I loved experimenting with new breakfast recipes in the actual morning. This was a time I refer to in my mind as my “Paleo honeymoon.”
Maybe some of you are still in yours. It’s a time defined by excitement. For Paleo food. Like in the honeymoon phase of a human relationship, Paleo does you no wrong during this time. The new foods, how you feel, how you look – it all just keeps getting better.
And then something happens. Maybe other family members are now interested in eating Paleo and they’re expecting you to be as generous and excited to cook for them as you are for yourself (oops.)
Maybe you don’t want to wake up 45 minutes earlier than your non-paleo self had to, just so you can chop veggies and fry bacon and eggs. Maybe you’re tired of cleaning your stove 3 times per day, and sick of going to work with bacon grease in your hair.
Maybe all of this is happening, all at the same time. Fear not! None of this means you need to give up Paleo eating or that you’re lazy. Heck no. It just means you need some good make-ahead breakfast recipes in your life, so you can grab and go (or grab, heat, and go) just like your pre-paleo self did.
I didn’t get really serious about having breakfast casseroles available and ready to go regularly until this past January when Adam and I both did the Whole30 together. Basically, when you’re feeding a big family paleo food, you need to approach breakfast the same as you might approach dinner, where PREP IS NECESSARY!
My original big breakfast casserole turned out to be a huge hit with so many of you, so I knew I had to revisit it and start thinking flavor variations. According to Adam, a Mexican themed twist on the original was in order. You really can’t go wrong with adding a little bit of spice, sausage and salsa to breakfast, right?!
If I could’ve made this absolutely perfect, I would’ve subbed the bottom sweet potato “crust” for plantains. But, I know from sad, painful experiences that plantains do not hold up so well when roasted and stored in the refrigerator. This really does make me sad because I love them so much!
But, there’s not much point in making a big breakfast casserole that won’t last for 5 days in the refrigerator, you see, so I stuck with sweet potatoes. I’m always amazed by how well sweet potatoes keep after cooking! Seriously, they are really the perfect Paleo carb 🙂
After the sweet potatoes, the casserole is layered with a mixture of breakfast sausage, peppers and onions, then salsa and finally an egg/coconut milk/nutritional yeast (Whole30 friendly!)/spice mixture. Bake, top with cilantro and serve with avocado. You have it all! I know you guys will love this one, let’s get cooking!

Hi Michele! Just wondering, do you think this recipe could be successfully cut in half? Is there anything you would do special to accommodate this?
Yes I think you can cut it in half and nothing would change. Hope that helps!
Any reason I couldn’t prepare ahead and refrigerate overnight then bake in the morning? Thank you!
I would separate the egg mixture if you’re going to do that since I’m not sure if it would oversaturate the other ingredients. You can bake and then reheat with good results in the morning though!
I love how you describe this in stages of the Paleo journey; having breakfast already made is ALWAYS a super nice thing.
I have this dream of consuming nothing but Mexican food at every meal, and I couldn’t be more excited that this recipe is bringing that dream closer to fruition. Cannot wait to try this!
Ooh I hope you like it!
As a Paleo fan, this breakfast sounds amazing … gotta try it soon!
You’ll love it 🙂
I am sure I will love it. Breakfast casseroles were a life saver on whole 30 and I have kept the habit of making one every Saturday since. I am happy to come from my long run on Sunday and have a delicious breakfast ready. And I love that it keeps me full until lunch at work. Will let you know when I make it.
You’ll definitely love it, casseroles really do make mornings so much more manageable 🙂
A word to say that I made this casserole over the week-end and it was delicious! And the leftovers are so so good! I doubled the salsa, just because I love it, and it is so full of flavour. Will definitely keep in my rotation! Thanks for this recipe!
Yay! That’s great that you liked it. Easy to play around with too as with most breakfast casseroles 🙂
Could I make this without the sweet potato? I’m diabetic and really have to keep my carb count low?
Absolutely 🙂
I don’t have time to get nutritional yeast. What would I use instead? I don’t need the recipe to be whole 30 or paleo
Is this able to be frozen?
Yes that should work fine 🙂
I don’t have nutritional yeast, what else can i use instead? this doesn’t have to be paleo or whole 30.
thank you in advance
Definitely parmesan or another favorite hard cheese 🙂
Hey there! I just wanted to say that I love your blog. I thought dieting would be really hard for me, but after discovering your blog, it has been surprisingly easy! Thank you so much!
That’s so great to hear! It means a lot to receive comments like this, so thank you so much for letting me know 🙂
Do you have to put nutritional yeast in it?
Nope, it will be fine without, it’s just for extra flavor 🙂
Could you eat this throughout the week if I made it Monday?
Yup it’s perfect for that 🙂 Should last in the fridge for 5 days, then just reheat the individual portions.
After making this once I thought I’d like to try a pizza version. I made it today with Italian sausage, green pepper, onion and mushrooms. I used pizza sauce in place of the salsa. Just added the nutritional yeast to the egg mixture. It is delicious!!!!
That sounds so delicious! Perfect!
How would you recommend making this ahead? Just bake everything following the recipe and reheat?
Yup that would work fine!
This was FANTASTIC! I made a homemade whole30 compliant copycat Chipotle chorizo sausage and that was great in this casserole. All my kids loved this too!
Sounds amazing! So happy you guys liked it 🙂
This is fantastic! I was just starting to get sick of breakfast casseroles, which is a tragedy because I’m all about cooking a meal once and eating it all week. Casseroles are great for that. The salsa makes a huge difference here! Finally excited to eat a breakfast casserole again. I used ground turkey instead of the sausage because I have a real tough time finding clean sausage that doesn’t break the bank and even with the turkey it was still delicious! I’ll definitely be making this again in the near future. My Paleo-hating mom even liked this which was also shocking 🙂
That’s awesome! You happy you liked it 🙂
What could I use instead of the coconut milk? Would almond milk work?
Made this yesterday, it turned out great, and I’m so happy it’s now ready for me in the fridge! Thanks so much for your blog, it really helps me stay on track with the Whole 30. Your recipes are delicious(!), diverse, and very easy to follow. Thanks again!
So happy to hear that! Glad you enjoyed this and other recipe too 🙂
Love this! How would it be without the coconut milk?
You can make it without and it won’t change much 🙂
Really nice breakfast recipe. Thanks for sharing such an easy and nice food recipe.
Absolutely love it. Started it with my first round of whole30 but keep on making it even after, as I like it so much and it keeps me full the whole morning. I need to keep my calories intake in control, so I was wondering what are the nutritional facts of it?
Thanks!
This was delicious, even my younger kids liked it!
Yay!
how many calories is in this Mexican Breakfast Casserole? I’m counting calories and I have no idea.
I am a Keto diet now, so how many carbs are in this dish? Thanks
Hello!! I am new to this site (found through Pinterest). I just made this recipe and am in love! I have a normal diet with no restrictions, but love incorporating whole30 recipes when I can. I will be making this again. I used homemade salsa for this recipe and topped it off with a little bit more once it was made. I had to share a piece with my parents, because I knew they would also be fans. Thanks!!
That sounds delicious and I’m so thrilled you enjoyed it!
Excellent! Everyone loved it.
I am currently on my 2nd Whole 30 journey and this a favorite breakfast to make. My whole family absolutely loves it!
Quick question: can this be made late in the afternoon and refrigerated for baking and serving the next morning for brunch?
It looks amazing!
Yes it works very well that way!
Any suggestions for a bell pepper substitute? I don’t tolerate them but I’m afraid if I just leave them out it will be lacking flavor.
I was curious if you ever considered changing the layout of your
website? Its very well written; I love what youve got to say.
But maybe you could a little more in the way of content so people
could connect with it better. Youve got an awful lot of text for only having 1 or
2 images. Maybe you could space it out better? fußballtrikots kinder kaufen EloiseRod fotbollströjor NCBTitus

This recipe was amazing! I found this and cooked it for the first time and came out perfectly. Great for brunch with my friends.
Can you do this with shredded sweet potato instead of cutting it into rounds?
Hi! I loved this recipe. How can I log this food in my fitness pal? I’m wondering what a serving size is and how many calories
Hey there! I just wanted to say that I love your blog. I thought dieting would be really hard for me, but after discovering your blog, it has been surprisingly easy!
