1 head cauliflower, cut into bite-sized pieces
1 tablespoon olive oil
Salt and freshly ground black pepper to taste
1/4 cup unsalted butter, plus more for greasing the baking dish
1/4 cup all-purpose flour
2 cups chicken stock
1 1/2 cups shredded Cheddar cheese, divided
1 cup sour cream
2 cups chopped cooked chicken
3 green onions, chopped
3 slices cooked bacon, crumbled

Directions

Step 1: Preheat the oven to 450F (230C). Line a sheet pan with parchment paper and grease an 8x8-inch baking dish with butter.

Step 2: Place the cauliflower pieces onto the prepared sheet pan. Toss with olive oil and season with salt and pepper to taste.

Step 3: Roast the cauliflower in the preheated oven for about 20 minutes, until tender but still firm. Once done, remove the pan from the oven and reduce the temperature to 350F (175C).

Step 4: While the cauliflower is roasting, prepare the sauce. In a large saucepan, melt the butter over medium heat. Stir in the flour and cook for about 3 minutes, until the mixture is bubbly and thickened.

Step 5: Gradually add the chicken stock to the saucepan, stirring continuously. Let the mixture bubble for 3 to 5 minutes, then remove from heat.

Step 6: Stir in 1 cup of the shredded Cheddar cheese until melted and smooth. Then add the sour cream, mixing well to incorporate.

Step 7: Add the chopped cooked chicken to the sauce and stir in the roasted cauliflower.

Step 8: Pour the chicken and cauliflower mixture into the greased baking dish. Bake at 350F (175C) for about 20 minutes, or until the casserole is bubbly and heated through.

Step 9: Once the casserole is ready, sprinkle the remaining shredded Cheddar cheese over the top. Add chopped green onions and crumbled bacon for garnish.

Step 10: Serve the casserole warm and enjoy!

History and Origin of Loaded Cauliflower Chicken Casserole

The Loaded Cauliflower Chicken Casserole is a modern twist on traditional American comfort food, inspired by the classic loaded baked potato casserole. While casseroles have been a staple in American households since the early 20th century, the substitution of cauliflower for potatoes emerged as part of the low-carb and keto-friendly movement in the 2010s. Home cooks began experimenting with roasted vegetables as a nutritious alternative to starch-heavy ingredients, resulting in this creamy, cheesy dish that retains all the indulgence of its potato-based predecessor.

Regional Variations and Features

This casserole is particularly popular in the United States, where regional interpretations vary. In the South, it is common to find added spices such as paprika or cayenne to give the dish a subtle kick. Northern variations may incorporate different cheeses like Gruyre or Swiss for a richer flavor profile. Some regions blend cauliflower with broccoli or even roasted carrots to diversify the texture and nutritional content. Despite these differences, the core ingredientscauliflower, chicken, cheese, sour cream, and baconremain consistent.

Comparison with Similar Dishes

While this casserole shares similarities with Chicken Divan and loaded baked potato casseroles, it stands out due to its vegetable-forward approach. Unlike Chicken Divan, which often features broccoli and a curry-flavored sauce, the Loaded Cauliflower Chicken Casserole emphasizes roasted cauliflower as the central ingredient, creating a unique texture and slightly nutty flavor. Compared to a traditional potato casserole, this dish is lighter, lower in carbohydrates, and often appeals to those seeking a healthier comfort food alternative without sacrificing richness.

Typical Serving Occasions

Loaded Cauliflower Chicken Casserole is commonly served at family dinners, holiday gatherings, and potlucks. Its hearty nature makes it ideal for weeknight meals, while its creamy, cheesy topping and visual appeal allow it to hold a place at celebratory tables. It is often accompanied by a simple side salad or garlic bread to complement the rich flavors, and it pairs well with white wine or a light, crisp beer.

FAQ about Loaded Cauliflower Chicken Casserole Recipe

This sounds amazing but could you use frozen cauliflower instead? If so how many ounces and what changes if any would need to be made to the instructions?

This was fast and delicious!! I added two pinches of garlic powder and black pepper to the sauce. This helped to elevate it's flavor. Trader Joe's Unexpected Cheddar was perfect for this dish. Julie

This was great. I used Greek yogurt in place of the sour cream, replaced some of the butter with olive oil and used Mozzarella instead of cheddar. I did this because this was what was in my kitchen. I also did not use bacon or green onion as I did not have these either. I added garlic and onion powder to the sauce. I will make this again. Husband loved it.

I didn’t have leftover chicken so I diced a chicken breast seasoned with pepper and garlic salt and sautéed with 1\2 chopped onion. I prepped 3/4 of a large cauliflower per recipe. I didn’t really measure the cheese, I may have had a little more than specified. I added some coked bacon pieces right in the sauce as well as a few with onion greens on top. The remainder I did as recipe described. Not too soupy. Delicious!!

The only change I made was to use broccoli in place of cauliflower. While both are nutritritous, broccoli is is much more nutritious than cauliflower, with more vitamins, minerals and fiber. Broccoli is also good for eye health. Taste is similar. It looks prettier, too! Otherwise, no changes. Delicious!! Thank you...

Holy cow this is amazing! I don’t normally try recipes, unless they have many more reviews than this one does, but I sure am glad that I did. I’m also not want to change a recipe without trying it first, but in this case, for health reasons, I made sure I used fat-free cheddar cheese, and I substituted plain Greek yogurt for the sour cream. it was absolutely fantastic! My boys, who are 20, went back for thirds! Thank you for submitting!

added green capsicum to the main body of meal and also added some to the crumb at the end. Only used 1/2 cup of homemade chicken stock & otherwise kept to the recipe. Will be making this often. :)

I did change it up a little. I added sautéed sliced white mushrooms & spinach. I also used Romano cheese rather than cheddar.

We enjoyed this casserole very much. I added additional 1cup cheese and a second large head of cauliflower and it was still very creamy and full of flavor. Next time I’ll try cutting down the calories by steaming the cauliflower instead of baking it.

One of my husbands favourites. Have made it with fresh and frozen cauliflower. Sometimes I add some diced cooked potato to make a bigger casserole.

Bland and lacking texture. It's more of a thick cheese soup with bits of cauliflower and chicken.

Made it once and now it’s a staple.

Lacked flavour; needed something like dry mustard and paprika or lemon pepper and Italian seasoning. Also lots of sauce, so serve with rice or pasta or fresh bread to soak it up.

I used a little sherry and curry powder in the sauce. Mixed broccoli with cauliflower. A chicken Divan riff.

Made it as written. We really liked it. Only reason for 4 stars is that some people may consider it a little bland. But we really liked it!
