How to Make Low Carb Chicken Casserole
The process is simple, and you don’t need fancy ingredients. Here’s the step-by-step:
Step 1: Prep Your Cauliflower Rice
You can use fresh cauliflower that you pulse in a food processor or grab a bag of frozen cauliflower rice from the store. Either way works! Cook it first to release any excess moisture—this keeps your casserole from turning watery.
Step 2: Steam the Broccoli
While the cauliflower is cooking, steam your broccoli florets until tender but still vibrant. A little crunch is okay since it will continue to soften in the oven.
Step 3: Cook the Bacon
No casserole is complete without bacon, right? Fry it up until it’s crisp, then crumble it into bite-sized pieces. This adds smoky flavor and a satisfying crunch.
Step 4: Combine Everything
In a large mixing bowl, toss together the cauliflower rice, broccoli, shredded chicken, crumbled bacon, eggs, cheddar cheese, and seasonings. Give it a good stir so everything is coated evenly.
Step 5: Bake Until Golden
Spread the mixture into a greased 9×13 baking dish, sprinkle with a little extra cheese on top (because more cheese is always the answer), and bake for about 30 minutes at 350°F.
When it comes out of the oven, you’ll have a bubbling, cheesy, golden casserole that screams comfort food but keeps your carbs low.
