This Whole30 breakfast bake with sausage, eggs, spinach, and mushrooms is flavorful enough to live off of during a Whole30. You’ll love this Whole30 breakfast because it’s packed with flavor, protein, and fiber, making you feel a-freaking-mazing all day. This might just become your new favorite paleo breakfast bake! Perfect with my easy Whole30 breakfast sausage recipe.
I know I lament the eggy Whole30 regularly, and it’s true! I tire quickly of savory eggs every morning for breakfast. I need the dominant flavor of a dish to be, well, not eggs, so the fact that this Whole30 sausage egg passes muster says a lot.
Any time we’re on a Whole30, I spend a couple hours on Sunday afternoon, making dishes for the week. This usually looks like a batch of Whole30 garlic mayonnaise, Whole30 chicken salad, Whole30 ranch dressing, and my Whole30 bread pudding (OMG. I could–and can–eat this every single day.). But one Sunday, I was struck by the strangest, strongest urge to make a sausage and veggie bake, filled with chopped spinach, fresh tomatoes, sautéed mushrooms, homemade spicy breakfast sausage, and fresh herbs.
And you know what? I never tired of eating it that week, not once! No, I fell in love with the creamy egg bake, the rich sausage, the fresh veggies, the flavorful herbs.
Even better, I felt amazing after eating it, which is one of my very favorite things about eating a Whole30 breakfast. There’s no heaviness or energy slump. Nah, you feel light and energized and full until lunch. With loads of veggies and plenty of protein, this Whole30 breakfast bake with sausage, eggs, spinach, and mushrooms might just be Whole30-perfect.
You’ll love this dish because it’s the Whole30 breakfast bake for Whole30 breakfast bake haters. It’s packed absolutely full of flavor and contains tons of protein. It isn’t heavy, and there’s great fiber content, too. This dish is one where I combined basically everything good I could think of and included all my favorite veggies: sausage, mushrooms, tomatoes. We had fresh basil on hand, so of course I added it. However, you’d be fine without it, or you could substitute dried basil easily.
On top of being oh-so-flavorful, it’s super easy and pretty darn quick… major bonus points for anything Whole30, if you know what I mean. The directions go basically as follows: sauté stuff, pour eggs over, bake, um… eat? As much as I freaking love making mayonnaise all the time (liar, liar, pants on fire), I am all about some efficencies in the kitchen.
If you’re trying a Whole30 (and I really think you should), make sure you add this recipe to your meal plan! It’s fantastic, easy, and so healthy. It’s super versatile, so feel free to swap out any ingredients for what you have on hand. If you make it, tag me on Instagram @40aprons or use the hashtag #40aprons!

What can I sub for the mushrooms? Not a fan of them.
You could sub any veggie, like broccoli or asparagus. The recipe is very forgiving and versatile! Let me know what you choose and how you like it 🙂
5 STARS (The fifth star won’t light up.) I made this exactly as written for Easter yesterday. It was truly the best tasting egg dish I’ve had and everyone loved it. We are not doing Whole 30, I just thought this looked outstanding, and it was! Next time I’ll include some other veggies. Thanks for showing something like this can be great even without cheese… 🙂
Yay! I’m so glad you enjoyed it, even though you’re not on a Whole30! “Showing something like this can be great even without cheese” is basically the best compliment ever, ha! Thank you for 5 stars, despite our funky recipe plugin quirks 😉
Hello! I’m going to make this recipe this weekend. I have fresh spinach, do you recommend cooking it first before putting it in the casserole? And also can you recommend a substitute for marjoram?
I would chop it and sauté it lightly first, yes, but make sure you squeeze alllllll of the water out! You’d be fine with just chopping it and leaving it raw, too. Do you have poultry seasoning? That works to replace the marjoram too. There’s another whole30 breakfast sausage recipe on my blog, if you go to 40aprons.com (it should be on the homepage!), if you want to check it out. I hope you like it, and let me know if you have any other questions!
This was very flavorful and delicious! I added garlic powder and substituted pork with ground turkey and added more veggies that I personally like. Thanks for sharing the recipe. =)
I’m so glad you liked it! It’s so versatile, isn’t it? Thanks for your comment, Kim! ❤️
Looks greats! Quick question…. would this keep over the week and be ok reheated? Thanks!
Absolutely! I’ve done that several times 🙂
Just made this for dinner on day 25 of my first Whole30, and it is the best thing we’ve had yet! Incredible. Thank you for sharing!
That’s wonderful news! I’m so happy to hear that 🙂
This looks amazing. Can i make ahead and bake this in the morning?
Here’s what I’d do: make everything ahead but DON’T add the eggs yet. In the morning, crack all the eggs, pour over, and bake. That should only take you a couple minutes in the morning and will help the dish come out super fresh!
5 stars!!!
Thanks Anna!
I love the idea of this recipe!!!I am not on any specific diet, but am looking for healthier recipes to lose a few and not feel like I’m starving myself to do it. This looks so perfect!!! I plan on making this Monday morning, subbing the sausage with turkey, and eating the leftovers for breakfast all week! Super excited! Thanks for sharing!!
This makes perfect leftovers! I hope you like it 🙂
If I were to put in muffin cups what should I adjust the baking time to?
I don’t think you’d need to reduce the duration too much. Try 22 minutes!
Could you use canned diced tomatoes drained??
I think that could work! Make sure they are drained very, very well
Does this freeze well? I’m cooking for 1 so even halving recipes leaves with too much!
I haven’t tried it but i think it would freeze just fine!
How would you recommend reheating this?I want to make it Sunday and eat it throughout the work week!
If you use the microwave, it’s great in there! It doesn’t dry out that way. If you don’t, I’d just reheat it in a 300 degree oven for something like 10 minutes maybe?
If I were to freeze this would you suggest doing so before or after cooking? I am getting my freezer stocked for after baby arrives and this looks so delishious!
I would freeze it after cooking for sure! You could even bake it in muffin cups so it’s even easier to eat a quick and healthy breakfast during those exhausted newborn days!
I made a similar recipe in muffin cups – while it could work for convenience, washing the eggs out of each section can be a total pain! If you go that route, I’d recommend that you grease each section really well or use cupcake cups (though I’m not sure if the eggs would stick to those and end up kinda weird).
I’m going to try your way next week (Day 7 of Whole30 by then, woot!) because a single pan will be easier to clean. It goes a long way since Whole30 = 32490230948 dishes! Then I’ll cut up into portions for me and the husband, and we’ll be set for a few days. Thanks for this recipe and I’ll be checking out the rest of your site 🙂
If you make this in muffin tins, I would definitely recommend parchment cups! Those would be so perfect and would not leave any of that horrible egg crud on the pan… seems like it sticks forever, right?!
And yes, any time you can minimize dishes and prep on a Whole30, I call that a win!! I’m hope you like everything 🙂
Looks so yummy! If I make half the recipe, would you recommend reducing the baking time? Also do you think I could use an 8×8 pan for half Tyne recipe?
I wouldn’t halve the cooking time, but maybe start checking it around 20 minutes. And I think an 8×8 would work pretty well!
My fiance and I are on Day 8 of the Whole 30 and getting ready to make this. It looks amazing! Only thing is, we are completely out of spinach. We have everything else and lots of other veggies. Any suggestions for a spinach substitute? Thanks!
Hi! If you have any sort of greens, that’ll work fine. I’d make sure to steam kale or chard first. And honestly, if you leave out the spinach entirely, you’ll be fine – I just love getting my greens in in the morning!
Hi! I love this bake! My husband and I ate this practically every day of our whole 30 last time we did it. I am getting ready to try the Keto this time around and am trying to prep some foods ahead of time and wondering if u think that this would turn out ok if I made it and froze and then defrosted it in a few weeks when I begin my challenge? Thank you:)
I’ve heard it freezes really well! Let me know if you try it, and good luck! 🙂
I don’t use whole eggs. Do you think the equivalent of egg beaters would work?
I don’t see why not!
This is amazingggg! I was a little nervous ab all the spices but oh my goodness everything blends together so well! How long would you say this will keep in the fridge?
I would say a week!
Hello, after mixing the sausage ingredients, do I cook the sausage before adding it to the casserole dish? Thank you!
Yes, simply follow the directions under the breakfast casserole heading after 🙂
What are the nutrientian facts on this? I made it and love it, thanks!
