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!

Yeah slightly obsessing over here. I mean, another way to eat tacos? And first thing in the morning? Sign. Me. Up.
I made this last night and had it for breakfast this morning. It was AMAZING!!!!!!
So glad you loved it, Sarah!! Thanks for the great feedback!
I made this Saturday and it will be a new staple in the breakfast lineup. My husband admitted he likes it better than my grandma’s egg casserole (sorry, Grandma!) And my toddler loves it too. Win-win!
Oh my gosh – such a compliment! Sorry, Grandma!! <3
This looks delicious! I actually have a stack of corn tortilla in the freezer left over from….something, I can’t even remember what. I’m making this with them! Thanks =)
Hello there! I’m a huge fan of ALL your recipes! Could you get most of this ready to roll the night before then just throw it in the oven in the AM? I wonder how much modification you’d have to make on the baking time…?
Yes, absolutely, I’ve done it that way too! I cooked the sausage, vegetable, and egg components the night before, sliced the cheese and tortilla strips too. Right before assembling the next day I made the cheese sauce fresh. It came together really quickly and baking time was the exact same!
Awesome recipe! This was such a hit at a brunch I hosted yesterday! I added 505 Green Chile sauce to the cheese sauce and a can of diced green chilies to the pepper/onion mix. I also used half chorizo – half breakfast sausage. Phenomenal!
Love the additions – I will definitely have to try that. I was thinking a chopped jalapeno would be really good in the vegetable mix – would give it that spicy nacho cheese kind of taste!
Any kind of taco, mexican food, anything is my favorite!!!!! Basically I wish cinco de mayo could be all year long!
When I saw this Friday I just knew I had to make it ASAP. As a Texas girl, breakfast tacos are one of my all time favorite meals. I made this Sunday and all I have to say is you nailed it! This is fantastic.
Yesss! Music to my ears – I’m so glad you loved it, Sarah!
My most favorite is chicken tacos. Are you with me??
Your recipe says add th “scrambled” eggs, but do you mean beaten eggs? I just made this and as soon as I scrambled them in the pan I had the thought they should have been just beaten and added raw. It’s in the oven now, but I’m only cooking for half the time to hopefully not over cook the eggs.
Nope you did it right! They’re scrambled in the skillet just until set ,then baked in the casserole.
Looks so yummy!! I make hubby and myself tacos often. Promise it’s quick and easy. Stuff a tortilla with scrambled eggs, salsa and cheese (fresh cilantro when it’s in the fridge chopped)… so satisfying. Plain scrambled eggs for my two little ones.
Oh my goodness!!!!!!!!! Why hadn’t I thought of this before?!?! Totally making it this weekend!!!
Yay!! Let me know what you think, Angela!
Thanks for the recipe. Think I will try topping with salsa or taco sauce instead of the cheese sauce for a lower calorie meal, but definitely will try it out soon!
Good idea! I hope you love it, Ashley!
