What You’ll Need (Ingredient Highlights)
Chicken breasts – boneless and skinless, cut into bite-sized chunks for even cooking.
Fresh asparagus – adds a bright, crisp contrast to the creamy sauce.
Mushrooms and onions – build deep, earthy flavor.
Heavy cream & mayo – create a luxuriously rich sauce.
Dijon mustard & lemon juice – add zing and balance to the creaminess.
Gouda & parmesan cheese – gooey, melty, and savory.

Pro Tips Before You Start
Steam the asparagus just until tender—it will finish cooking in the oven.
Cut chicken pieces evenly so they cook at the same rate.
Use a good quality mayonnaise (avocado oil mayo works great).
Don’t rush the sauce—let it simmer and reduce to deepen the flavor.
How to Make Creamy Chicken and Asparagus Casserole
Step 1. Prep the Oven & Asparagus
Preheat oven to 375°F. Place asparagus in a microwave-safe dish with a splash of water.
Cover and steam for about 3 minutes until just tender. Drain and set aside.
Step 2. Cook the Chicken
In a large skillet, melt butter over medium-high heat.
Add chicken pieces and cook 3–4 minutes per side until golden and cooked through.
Transfer the chicken to a greased casserole dish.
Layer the steamed asparagus over top and cover to keep warm.
Step 3. Sauté the Vegetables
In the same skillet, sauté onions and mushrooms over medium heat until soft and fragrant.
Step 4. Make the Creamy Sauce
Lower heat to medium.
Add broth, cream, salt, pepper, thyme, mayonnaise, Dijon mustard, and lemon juice.
Whisk together and simmer gently for 8–10 minutes until reduced and slightly thickened.
Step 5. Assemble the Casserole
Pour the creamy mixture over the chicken and asparagus.
Stir in shredded gouda and half of the parmesan. Mix to combine.
Step 6. Top & Bake
Sprinkle the remaining cheeses on top.
Bake uncovered for 30 minutes, until bubbly and golden.
What to Serve It With
A crisp green salad with vinaigrette.
Roasted potatoes or crusty bread.
Steamed rice or buttered noodles.
Variations / Substitutions
Swap asparagus for broccoli, green beans, or spinach.
Use Swiss cheese instead of gouda for a sharper flavor.
Add cooked bacon or pancetta for a smoky twist.
Replace mayo with sour cream if preferred.
Storage & Leftovers
Store in an airtight container in the fridge for up to 3 days.
Reheat in the microwave or oven until warmed through.
Not freezer-friendly due to the dairy sauce separating.
FAQs
