Tools You’ll Need

• 9×13-inch baking dish
• Medium saucepan
• Large mixing bowl
• Whisk
• Skillet (if pre-cooking chicken)

Step-by-Step Instructions

Step 1: Prep the Chicken and Asparagus
Preheat your oven to 375°F (190°C).
Grease a 9×13-inch baking dish with a little olive oil or cooking spray.
Season the chicken pieces with salt, pepper, garlic powder, and onion powder.
Lightly sauté the chicken in a skillet over medium heat with 1 tbsp olive oil for 4–5 minutes until lightly browned (it doesn’t need to be fully cooked).
Add the cut asparagus to the skillet and cook for 2 minutes to slightly soften.
Transfer chicken and asparagus to the prepared baking dish.

Step 2: Make the Creamy Sauce
In a medium saucepan, melt butter over medium heat.
Add minced garlic and sauté for 30 seconds until fragrant.
Whisk in flour and cook for 1 minute to make a light roux.
Gradually pour in chicken broth while whisking to avoid lumps.
Add milk and heavy cream, continuing to whisk until smooth.
Season with thyme, Italian seasoning, paprika, crushed red pepper flakes, and a pinch of salt and pepper.
Let the sauce simmer for 4–5 minutes until it thickens.
Taste and adjust seasoning as needed.

Step 3: Assemble the Casserole
If using rice or pasta, spread it evenly in the bottom of the casserole dish.
Pour the creamy sauce over the chicken and asparagus.
Gently mix to coat everything evenly.
Sprinkle the shredded mozzarella and grated Parmesan cheese over the top.

Step 4: Bake to Perfection
Cover the dish with foil and bake in the preheated oven for 20 minutes.
Remove the foil and continue baking for another 10–15 minutes, or until the cheese is bubbly and golden on top.
For an extra golden finish, broil for 1–2 minutes at the end—watch closely!

Step 5: Garnish and Serve
Let the casserole rest for 5 minutes before serving.
Garnish with freshly chopped parsley for a burst of color and flavor.
Serve warm and enjoy the creamy, cheesy goodness in every bite.

Tips for Success
Pre-Cook the Chicken – Lightly browning the chicken adds flavor and ensures it’s fully cooked in the casserole.
Don’t Overcook Asparagus – A quick sauté keeps it vibrant and crisp-tender.
Use Fresh Mozzarella – For extra gooey, creamy melt.
Thicken the Sauce Properly – Make sure your sauce isn’t too runny before baking.
Let It Rest – Cooling slightly after baking helps everything set.

Serving Suggestions
Garlic Bread – Perfect for soaking up the creamy sauce.
Side Salad – A crisp green salad with lemon vinaigrette balances the richness.
Steamed Veggies – Add more color with carrots, peas, or green beans.
Fruit Salad – For a light and refreshing contrast.

How to Store & Reheat

Storing:
Refrigerate: Store leftovers in an airtight container for up to 4 days.
Freeze: Freeze in individual portions for up to 2 months (leave off the garnish).

Reheating:
Oven: Cover with foil and reheat at 350°F until warmed through (about 15 minutes).
Microwave: Heat in 1-minute intervals on medium power, stirring in between.
Add a splash of milk or broth if the sauce has thickened too much.
