Tips for making the best keto chicken fajita casserole:
- I bought shredded chicken already cooked from the store for convenience. You can boil chicken breasts instead, and then shred the meat for this recipe.
- I compiled a homemade keto fajita seasoning for this casserole — it really tastes so much better than store-bought. However, if you’re running short on time, feel free to grab a package of your favorite low-carb taco seasoning instead.
- I didn’t drain the can of Rotel tomatoes when adding them to this recipe. By not draining, it really boosts the flavor while achieving the perfect consistency.
A real fiesta for your taste buds!
This keto chicken fajita casserole combines all of my favorite Mexican-inspired flavors into one delicious dish. I love ordering fajitas at restaurants when I go out and I always skip the tortillas to save on carbs. But with this casserole, you won’t even miss them. I gotta tell ya, it’s even better reheated the next day for lunch. 😋

Here’s what my teammate Jenna had to say about this recipe:
“This keto chicken fajita casserole is so tasty! I love the fresh-tasting peppers combined with the creamy chicken. The homemade keto taco seasoning really gives it a great flavor, and the cream cheese all mixed in is such a home run. Also, this reheats beautifully, and I may or may not have had some for breakfast the next morning! 😋”
