Breakfast Taco Casserole is breakfast taco ingredients layered in casserole form. This gluten free breakfast recipe is cheesy and satisfying!

It feels like everyone I know has been to Austin, TX sometime in the past 6 months and the taco shots they’ve been sharing on Instagram have me drooling
Chicken tacos, pork tacos, and—oh yes—breakfast tacos. We adore tacos but the breakfast ones in particular aren’t exactly ‘wild mornings + 3 young children’ friendly. Until things are a little less chaotic, I’ll be layering classic breakfast taco ingredients in a casserole dish, dousing them with homemade cheese sauce, then calling it a day.
Or rather, Breakfast Taco Casserole.
This twist on traditional breakfast casserole will knock your socks off!

Breakfast Casserole with a Taco Twist
Cooked breakfast sausage, sauted onions and peppers, and fluffy scrambled eggs are layered in a casserole dish with corn tortilla strips then drizzled with homemade cheese sauce and baked until bubbly. SO DELICIOUS!
This breakfast casserole is perfect for taking to a work potluck or serving on a holiday morning to feed a crowd, but it also reheats wonderfully so you can bake once then reheat and eat for easy breakfasts all week long.
The cheese sauce gets nice and saucy again after being warmed in the microwave — it’s such a treat.

How to Make This Recipe
Step 1: Brown breakfast sausage.
Start by browning gluten free breakfast sausage in a large skillet over medium-high heat then scoop into a bowl and set aside. I like Jimmy Dean brand breakfast sausage.

Step 2: Saute peppers and onions.
Heat a drizzle of extra virgin olive oil in the skillet then add chopped green peppers and yellow onion. Season with salt and pepper then saute until the vegetables are tender, 8-10 minutes, turning the heat down slightly if they begin to burn. Scoop into a bowl then set aside.

Step 3: Scramble eggs.
Turn the heat down to medium then add eggs that have been whisked with milk, salt, and pepper. Scramble just until they’re set then, you guessed it — scoop into a bowl or plate and set aside!

Step 4: Make the homemade cheese sauce.
Melt butter in a saucepan over medium heat then sprinkle in gluten free flour (or all-purpose flour if you don’t need to eat GF) and whisk for 1 minute. Slowly stream in milk while whisking to create a smooth sauce then turn the heat up slightly to bring the sauce to a gentle simmer.
Turn the heat back down to medium/medium-low then stir until the sauce has slightly thickened, a couple minutes. Finally, remove the pan from the heat then add freshly shredded sharp cheddar cheese and stir until smooth. Season with salt to taste.
Recipe Tip
DO NOT let the milk boil, which can lead to a grainy cheese sauce! Adjust the heat as needed to maintain a very gentle simmer.

Step 5: Slice tortillas into strips.
Last step is to slice gluten free yellow corn tortillas into 1″ (ish) strips. I like Mission Yellow Corn Tortillas.

Step 6: Assemble then bake casserole.
Spray a 9×13″ baking dish with nonstick spray then spread 3/4 cup cheese sauce in the bottom. Next add 1/2 the tortilla strips, 1/2 the sausage, 1/2 the vegetables, 1/2 the eggs, and 1/2 the remaining cheese sauce.
Repeat the layers one more time then cover with nonstick sprayed foil and bake for 30 minutes at 400 degrees, or until the cheese sauce is bubbling.

Let the casserole sit for 15 minutes before slicing and serving. I’m telling you – total breakfast epicness!
Keep the leftover casserole in the fridge then slice, reheat, and eat for breakfasts all week long. Enjoy!

I have just recently discovered your sight and this was the first recipe I tried………it ROCKS!! I did add some chorizo and a tad salsa to the last of the cheesy sauce but other than that, it will be on my rotation of favorites recipes. THANKS!!!!
YUM – great addition! I’m so glad you enjoyed, Mary!
I’d like to make this for a tailgate tomorrow but don’t want to get up early enough to do all the work. If I assemble it today, do you think it would turn out ok? Would you do the final bake in the morning or do it both today and tomorrow? Thanks in advance!
Delicious! Served it for Christmas morning brunch – devoured. No leftovers (which I was selfishly hoping for!). I had left over tortilla strips so next time, I’ll reduce the tortillas to twelve. Used half spicy, half mild sausage (love Haggerty’s brand – gluten free!). Salsa makes a nice accompaniment.
Wonderful recipe, Kristen – thanks so much!
Looks so delicious! I will definitely tell my wife to make this for me this weekend. One question: what do you suggest instead of cheese as my doc will not allow?
Can you make this the night before and bake the morning of? Or will the corn tortillas be too soggy after sitting overnight? Thanks
We loved this recipe the first time I made it! About to make again for Christmas breakfast and wondering your thoughts on leaving the tortillas whole and layering instead of slicing into strips. Any watch-outs that I’m overlooking? Thanks!
I think that would be ok! I worry a touch about the overlapping tortilla sections being a little bit harder then just a single layer, but I’m sure they’d steam and soften just fine inside the casserole.
I have a feeling my wife is going to love me just a little bit more after I make these for her:)
My 1.5 and 4 year old each asked for 2nds. If that isn’t confirmation that this recipe is a WINNER, I don’t know what is! :)
Made my day!! So glad to hear the whole family enjoyed!!
I’ve made this several times…It’s amazing! I’ve also used Johnsonville Monterey and Chipotle chicken sausage in place of breakfast sausage and it was equally yummy.
Yuuuuum – love that idea!! I’m so glad you loved it, Kayla, and thank you for the feedback!
My cheese sauce was a bit runny. I’m not sure I added enough flour, but I still put it in to bake. Hoping it turned out ok. Some times I’m cooking impaired!
Wow! I love this gluten-free breakfast recipe. I tell you that I will definitely try this. Hope it will be great.
Thank you.
