Ingredients

• 2 tablespoons olive oil

• 1 pound boneless, skinless chicken breasts, cut into bite-sized pieces

• 1 teaspoon garlic powder

• 1 teaspoon onion powder

• ½ teaspoon paprika

• Salt and black pepper to taste

• 1 medium head of cauliflower, cut into small florets

• 1 cup broccoli florets

• 1 cup shredded cheddar cheese

• ½ cup cream cheese, softened

• ½ cup sour cream

• ½ cup heavy cream

• ½ teaspoon dried thyme

• ¼ teaspoon red pepper flakes (optional)

• 2 tablespoons grated Parmesan cheese

• 2 tablespoons chopped fresh parsley for garnish

Directions

1. Preheat the oven and prepare your baking dish
   Begin by preheating your oven to 375°F (190°C). This ensures that the casserole will bake evenly once assembled. While the oven is heating, lightly grease a 9×13-inch baking dish using either a small amount of olive oil or a nonstick cooking spray. Greasing the dish prevents the creamy casserole from sticking to the sides and makes cleanup easier afterward. For an extra touch, you can even sprinkle a tiny bit of grated Parmesan on the bottom of the dish, which adds subtle flavor and helps keep the casserole from sticking.

2. Cook the chicken
   Next, take a large skillet and place it over medium heat. Add two tablespoons of olive oil to the pan, allowing it to warm for about 1–2 minutes. Once the oil is hot, add the bite-sized pieces of chicken breast. Before adding them, season the chicken with garlic powder, onion powder, paprika, salt, and freshly ground black pepper. These spices enhance the flavor of the chicken and create a fragrant aroma as it cooks.

   Cook the chicken for approximately 5–6 minutes, stirring occasionally, until each piece turns golden brown on the outside. This initial sear locks in the juices, ensuring the chicken remains tender during baking. Be careful not to overcook the chicken at this stage, as it will continue cooking in the oven. Once the chicken is nearly cooked through, remove it from the skillet and set it aside on a plate. Cover it loosely with foil to keep it warm while you prepare the vegetables and sauce.

3. Steam or blanch the vegetables
   While the chicken is cooking, it’s time to prepare the cauliflower and broccoli. Steam or blanch the florets for 3–4 minutes until they are slightly tender but still retain a firm bite. This step ensures the vegetables will not become mushy during baking. To steam, place the florets in a steamer basket over boiling water and cover with a lid. If you prefer blanching, bring a pot of water to a boil, add the vegetables for 2–3 minutes, then immediately transfer them to a bowl of ice water to stop the cooking process. Drain any excess water thoroughly, as too much moisture can make the casserole watery.

4. Prepare the creamy sauce
   In a medium mixing bowl, combine the cream cheese, sour cream, heavy cream, dried thyme, and red pepper flakes if you enjoy a touch of heat. Using a whisk, blend the ingredients until the mixture is smooth and creamy. The sauce should have a velvety texture that will coat the chicken and vegetables evenly. If you prefer a slightly thinner sauce, you can add an extra tablespoon or two of heavy cream. Taste the sauce and adjust the seasoning with salt and pepper as needed. This step allows you to customize the flavors to your liking before baking.

5. Assemble the casserole
   Now that all the components are ready, it’s time to assemble the casserole. Start by layering the steamed cauliflower and broccoli evenly across the bottom of the prepared baking dish. Next, add the cooked chicken on top of the vegetables, spreading it out evenly so that every serving will have a balance of protein and veggies. Pour the creamy sauce over the chicken and vegetables, ensuring it covers everything completely.

   Once the sauce is evenly distributed, sprinkle one cup of shredded cheddar cheese over the top. This will melt in the oven and create a luscious, gooey layer of flavor. Finally, finish with a light dusting of Parmesan cheese. The Parmesan adds a slightly nutty, savory note and will help develop a beautiful golden crust during baking.

6. Bake the casserole
   Place the assembled casserole into the preheated oven. Bake for 15–18 minutes, checking occasionally to ensure the cheese is melting evenly. You’re looking for the top layer to become bubbly and slightly golden brown. The aroma of melted cheese and seasoned chicken will fill your kitchen, signaling that your meal is almost ready. If desired, for a crispier, golden top, you can switch to the broil setting for 1–2 minutes at the end of baking, but watch carefully to prevent burning.

7. Garnish and serve
   Once the casserole is done, remove it from the oven and let it cool for 3–5 minutes. This short resting period allows the flavors to meld and makes it easier to serve. Just before serving, garnish with freshly chopped parsley for a pop of color and a subtle fresh flavor. Use a spatula to scoop generous portions onto plates and enjoy this warm, creamy, low-carb meal that comes together in just 30 minutes.

   Every bite combines tender chicken, lightly crisp vegetables, and rich, cheesy sauce, making it perfect for a weeknight dinner, meal prep, or even a casual gathering with friends. Pair it with a simple side salad or low-carb bread for a complete, satisfying meal.
