Step 1: Prepare the Broccoli
Option 1: Steam (Best Texture)
- Steam broccoli for 3–4 minutes until bright green and slightly tender.
- Do not overcook—it will soften more in the oven.
Option 2: Microwave
- Place broccoli in a bowl with a splash of water.
- Cover and microwave for 2–3 minutes.
- Drain well.
Set aside.
Step 2: Cook Aromatics
- Heat olive oil or butter in a skillet over medium heat.
- Add onion and cook for 3–4 minutes until soft.
- Add garlic and cook for 30 seconds.
- Add salt, pepper, paprika, and thyme.
- Stir and remove from heat.
Step 3: Prepare the Chicken
- Shred or dice cooked chicken.
- Add to a large mixing bowl.
- Combine with cooked onion-garlic mixture.
Step 4: Make the Creamy Sauce
In a saucepan over medium-low heat:
- Add cream cheese and chicken broth.
- Whisk until smooth and fully melted.
- Add heavy cream and sour cream.
- Stir until creamy and slightly thickened.
- Add:
- Cheddar cheese
- Mozzarella cheese
- Garlic powder
- Onion powder
- Dijon mustard (optional)
- Cayenne (optional)
- Stir until cheeses melt into a smooth sauce.
The sauce should be thick, rich, and pourable.
Step 5: Combine Everything
In the bowl with chicken:
- Add steamed broccoli.
- Pour creamy sauce over the mixture.
- Mix gently until everything is well coated.
Step 6: Assemble the Casserole
- Preheat oven to 190°C (375°F).
- Grease a 9×13-inch baking dish.
- Pour mixture into the dish.
- Spread evenly.
Step 7: Add Topping
Sprinkle on top:
- Cheddar cheese
- Parmesan cheese
- Pork rinds or almond flour (for keto crunch)
Step 8: Bake
Bake for 30–35 minutes.
It is done when:
- Top is golden and bubbly
- Edges are slightly crisp
- Center is hot and set
Step 9: Rest Before Serving
Let casserole rest for 10 minutes before slicing.
This helps it firm up and hold shape.
