Chicken Cauliflower Casserole is an easy-to-make dish that is full of cheesy goodness while still being high in protein and low in carbs, calories, and fat. It makes for the perfect healthy dinner choice!
What’s not to love about cauliflower? It’s nutritious, versatile, low in carbs, high in fiber, and has a mild enough flavor that it can be snuck into just about any dish. It adds nutrients and bulk to a meal while taking on the flavor of whatever you pair it with – without adding a lot of calories. (An entire medium head of cauliflower has fewer than 150 calories!)
When stated like that, cauliflower pretty much sounds like the perfect vegetable! Unfortunately, I feel like cauliflower tends to be a little ignored in the vegetable world. People like to focus on green veggies like kale, spinach, and asparagus, or other colorful veggies like carrots, peppers, and squash. Cauliflower comes across as a little bland or even less nutritious because of its pale white color.
That couldn’t be further from the truth! Cauliflower is an excellent and vitamin-rich vegetable choice, and it plays a big role in this delicious cauliflower casserole recipe.
How to make Chicken Cauliflower Casserole
This low-carb Chicken Cauliflower Casserole is super easy to make and makes such a great choice for dinner or even lunch. Check out this tasty list of ingredients:
- Chicken
- Bell peppers (both red and green)
- Salsa (you can choose any type of salsa)
- Cauliflower rice (cauliflower processed in a food processor until it resembles grains of rice)
- An egg
- Cheddar cheese
- Spices: cumin and paprika
- Toppings: limes and cilantro
What’s really interesting about Chicken Cauliflower Casserole is how the cauliflower is used to create the base of the dish.
Step 1 – Soften the cauliflower rice (or “riced cauliflower” as some people like to call it) by cooking them for about 5 minutes in a skillet and then drain the excess moisture. (It’s really important to drain the excess moisture or you’ll be left with soggy cauliflower casserole.)
Step 2 – Mix the drained cauliflower rice with most of the cheddar cheese (leave a little cheese for topping the casserole) and the egg.
Step 3 – Take this mixture and spread it evenly in a baking dish that has been lightly greased with extra virgin olive oil. Then bake it for 20-25 minutes at 375F (190C).
Yep, you create the bottom of your cauliflower casserole out of baked cauliflower, cheese, and egg. The mixture bakes up nicely and becomes firm and cheesy!
Step 4 – While the cauliflower crust bakes, sauté the bell peppers for 4-5 minutes and combine them with shredded chicken, salsa, and the spices. This mixture goes on top of the baked cauliflower, and it’s again baked (with the remaining cheese on top) for about 7 minutes to create the final dish.
I typically use a medium-spicy red salsa but you can use whatever you have available. The recipe is also great with a green salsa (salsa verde).
Once you add your toppings (lime and cilantro are suggested), it’s ready to eat!
