Step 1: Blanch the Broccoli (Medium-High Intensity)
-
Bring a medium pot of water to a boil over High intensity.
-
Add the fresh broccoli florets and blanch for just 2 minutes. You want them bright green and slightly tender, as they will finish cooking in the oven.
-
Drain immediately and submerge the broccoli in a bowl of cold water (an ice bath) to stop the cooking process. Drain thoroughly and pat dry with paper towels.
Step 2: Sear the Chicken (Medium-High Intensity)
-
Preheat your oven to $375^\circ\text{F}$ ($190^\circ\text{C}$) and grease a $9\text{x}13\text{-inch}$ baking dish with cooking spray or butter.
-
Season the cubed chicken pieces with garlic powder, onion powder, Italian seasoning, salt, and black pepper.
-
Heat $2\text{ tablespoons}$ of olive oil in a large skillet over Medium-High intensity.
-
Add the chicken cubes in a single layer and sear for 5 to 6 minutes, turning occasionally, until the edges develop a golden-brown crust. The chicken does not need to be cooked all the way through yet, as it will continue cooking in the oven. Transfer the chicken to your baking dish.
Step 3: Prepare the Creamy Cheese Sauce (Medium-Low Intensity)
-
Turn the skillet heat down to Medium-Low intensity.
-
Add the minced garlic and sautรฉ for 30 seconds until fragrant.
-
Stir in the softened cream cheese and heavy cream. Whisk continuously for 2 to 3 minutes until the cream cheese melts and the sauce becomes smooth and warm.
-
Add half of the mozzarella ($1\text{ cup}$) and half of the cheddar ($\frac{1}{2}\text{ cup}$) into the pan. Stir until completely melted into a rich, silky cheese sauce. Season with a pinch of extra salt and pepper.
Step 4: Assemble and Bake (Medium Intensity)
-
Add the blanched broccoli florets into the baking dish alongside the seared chicken.
-
Pour the hot, rich cheese sauce evenly over the top, making sure all pieces of chicken and broccoli are generously coated.
-
Top the casserole with the remaining mozzarella and cheddar cheeses.
-
Bake uncovered in the oven at $375^\circ\text{F}$ ($190^\circ\text{C}$) for 12 minutes, or until the sauce is bubbling around the edges.
Step 5: High-Heat Broil and Rest
-
Switch your oven setting to Broil (High intensity) for 1 to 2 minutes at the end of the baking cycle. Watch closely until the top layer of cheese develops dark golden caramelized spots.
-
Remove the casserole from the oven. Let it rest for 5 minutes before serving. This allows the hot cheese sauce to thicken slightly and settle around the chicken and broccoli.
Serving & Meal Pairing Suggestions
-
Classic Serving: Dish warm directly into low bowls, making sure every portion gets a mix of juicy chicken bites, crisp broccoli, and melted cheese.
-
Low-Carb Base: Serve over cauliflower rice or zucchini noodles to soak up extra cheese sauce.
-
Side Salad Pairing: Balance the richness of the dish with a crisp green garden salad dressed in lemon juice and extra virgin olive oil.
Storage & Reheating Instructions
-
Refrigeration: Allow leftovers to cool completely, then store in an airtight glass container in the refrigerator for up to 4 days.
-
Reheating: Reheat individual portions in the microwave on medium power for 1 to 2 minutes, or cover the baking dish with foil and heat in the oven at $350^\circ\text{F}$ ($175^\circ\text{C}$) for 10 to 12 minutes until hot throughout.
