This easy 21 Day Fix Make-Ahead Southwestern Breakfast Casserole is the perfect meal-prep or company breakfast! Great for brunches and holiday guests, it’s also gluten-free!
Hey guys… before we get to our regularly scheduled programming, I just want to say that my heart has been heavy this week thinking about the devastation from Hurricane Harvey to Texas and Puerto Rico. I hope you and yours are safe and I’m so grateful for and proud of all of the amazing work the U.S. Coast Guard and so many incredible volunteers have been doing. What a nation full of beautifully caring people we get to live in.
To donate $10 to the Red Cross Hurricane Harvey relief, you can text “HARVEY” to 90999 or click here to donate to other charities doing great work in Texas.
It’s kind of difficult to switch gears from that, but I’m going to do my best 🙂
Some of you may be familiar with my “OG” 21DF Sausage and Egg Breakfast Casserole (and if not, you should totally check it out, it’s the bomb!) – it’s been the #1 recipe on this blog for quite a while now.
What’s so great about both of these recipes is that they’re perfect for feeding a crowd (9 servings, my peeps!) and they’re great 21 Day Fix breakfasts for making on prep day to have throughout the week. Plus kids dig ’em and they’re gluten free! Basically these two casseroles are all of the good things.
Since the original was so beloved, I thought I’d make a new version of it and switch things up Southwestern style. If you guys don’t already know this, I’m in-freaking-love with the Smoky Southwest Seasoning in this recipe. I heart it so much that I’ve used it quite a few times on this blog:
- Slow-Cooker 21 Day Fix Southwestern Pulled Pork Tenderloin
- Avocado & Chicken Salad with Southwest Ranch Dressing
- 21 Day Fix Salmon Tacos with Deconstructed Guacamole
- Cheesy Southwestern Chicken Pasta Pie {Plus a Halloween Playlist!}
- Roasted Vegetable Chicken Chili with Avocado
I also use it when I make guac and you should too. And then you can just thank me later, nbd.
Btw, did I mention just how darn EASY this 21 Day Fix breakfast is?! Once you brown the meat and beat the eggs, all you have to do is layer it up (like so ⇓), refrigerate it overnight and then bake it up in the morning. There’s NOTHING better than not having any work to do in the morning when you have guests for breakfast!
The other thing that I love about this recipe is it’s SO customizable (another reason it’s so awesome for guests). You can use whatever veggies you like, plus it’s fun to have a bunch of topping options (different salsas, hot sauces, Greek yogurt, cilantro, etc..) to set out for company… guests love the options, people. You know what they say… variety is the spice of fun 😉

21 Day Fix Southwest Breakfast Casserole
This easy Make-Ahead Southwest Breakfast Casserole is the perfect breakfast dish to make for company! I love that I can just assemble it ahead of time and then throw it in the oven the day of!
Ingredients
Southwest Turkey:
- 1 lb ground turkey
- 3 Tbs Smokey Southwestern Seasoning (click here for recipe)
Casserole:
- 12 eggs
- 2 cups plain unsweetened almond milk
- 1/4 tsp salt and as much pepper as you like
- 2 cans of black beans (low sodium if you can find it), rinsed and drained
- Entire recipe of Southwest Turkey
- 4 cups of chopped vegetables (I used red & green bell peppers and green onions, but use whatever you like!)
- 3 cups colby jack cheese (or cheddar or monterey jack, whatever you have on hand!)
Optional toppings:
- Your favorite homemade or low-sodium, no sugar salsa - click here for mine!
- Cilantro
- Plain Greek yogurt (the best sour cream sub EVER!)
Instructions
- In a skillet over medium heat, add the turkey and the seasoning, breaking it up with your spatula as it cooks. Once it's cooked through, set aside to cool.
- Beat together the eggs, almond milk, salt and pepper, set aside.
- Spray a 9X13 (3 qt) baking dish with olive oil or coconut oil cooking spray. Then layer in this order, the beans, the southwest-seasoned turkey, the veggies and the cheese. Pour the egg mixture evenly over everything, cover and refrigerate overnight.
- In the morning: Uncover your baking dish and put it in the oven (do not preheat). Heat your oven to 350 degrees and bake for 1 hour or until the eggs have set in the center of the dish.
- Cut into 9 rectangles (3X3) and serve with whatever toppings you like!

How would this be with out the cheese?
I think it would still be great without the cheese!
We don’t like ground turkey or turkey sausage. Could I use breakfast sausage or extra lean ground beef? If so, how would that affect my container counts?
Hi! Breakfast sausage isn’t approved for 21DF, but extra lean ground beef will work perfectly and not affect your counts. Hope you love it!
Entire recipe of Southwest Turkey? I’m a little confused on that part. Can you help me out?
It just means after you cook the turkey with the southwest seasoning, you’ll use all of the cooked turkey in the recipe. 🙂
We had this for breakfast yesterday, prepared and refrigerated overnight, I baked according to your directions and I will say we loved it…I was a little skeptical of the portion size and container count so I went back and checked and it was 9 servings….was very filling! My problem is mine got really really watery after sitting in the fridge over night (I let it cool and let the lids off the containers), does your get watery? I am wondering if it was just the veggies? We still enjoyed it very much and I had it for lunch today, it is so filling and stays with you. Thank you for a satisfying dish!
I’m so glad you liked it!! Mine will always have a very small amount of liquid in the dish after it refrigerated, but never much. It could have been the veggies. Did you use more or different ones? Some veggies (like zucchini, for example) have a higher water content and would end up releasing more liquid when cooked.
I added some spinach and mushrooms to the sausage….it could have been from the mushrooms and some of the peppers. It is still delicious….this is my one of my snacks today!
Hmmm… maybe! Enjoy!
Hi! You advise baking in a 9 x 13 pan, however your 9 servings at 3 x 3 leave a 9 x 4 portion of casserole left – just want to understand if this is a 9 or 12 serving dish. Thanks!
Hi! It’s 9 servings – you’ll make 2 cuts vertically, then 2 cuts horizontally making it 3 pieces X 3 pieces. Sorry if that wasn’t clear in the post! Hope you had a wonderful holiday!
This looks amazing! Do you think this could be froze?
Thanks, Amanda! I think it would freeze really well!
Would you go ahead and bake the entire pan and then cool and freeze? What would the reheating instructions be?
Yes! That’s what I would do – or I might freeze in individual portions, because then I could heat up each portion in the microwave straight from frozen. If you freeze the whole pan, I would probably thaw it in the fridge first, but I’m not sure exactly how long that would take. If you bake it in an aluminum pan and then freeze it in that, I think you could pop it right in the oven frozen and it would be fine. 🙂
What does one slice equal out to with the 21-day fix portion containers?
Hey Tracey! It’s under “Notes” in the recipe card (in case you’re looking for container counts for another one of my recipes later, that’s where I always put it!) It’s 1/2 Green, 1 Red, 3/4 Yellow, 1 Blue (plus count any toppings). Enjoy!
Do you have to refrigerate over night or can you make and bake immediately?
You can bake it right away. It comes out a little differently but it’s still really good!
I am making this dish now, but I have a question. Am I supposed to put the egg dish in a cold oven? Or am I supposed to preheat the oven to 350 and then put it in? Thank you! I can’t wait to get this in my belly! 🙂
Yep, I put them in a cold oven then I turn it on (I’m always afraid of putting a cold glass dish from the fridge into a hot oven). Enjoy!!
