Step‑by‑Step Instructions for Creamy Asparagus Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your Creamy Asparagus Chicken Casserole will bake evenly, resulting in a bubbly, golden top. Set your timer for a few minutes while you prepare the asparagus and chicken, so the oven is ready when it’s time to bake.
Step 2: Steam the Asparagus
In a microwave-safe dish, add your asparagus with ¼ cup of water. Cover it tightly and steam in the microwave for about 3 minutes, or until it’s bright green and slightly tender. Once done, drain the water and set the asparagus aside to keep it warm and vibrant for your casserole.
Step 3: Cook the Chicken
In a large skillet, melt a generous tablespoon of butter over medium-high heat. Once sizzling, add the boneless, skinless chicken breasts cut into 1-inch pieces. Cook for about 6 minutes, stirring occasionally until the chicken is browned and cooked through. Remove the chicken and transfer it to a greased casserole dish, then top it with the steamed asparagus.
Step 4: Sauté the Aromatics
Using the same skillet, toss in the chopped onion and sliced mushrooms. Sauté for about 4-5 minutes until they’re tender and fragrant. This step will deepen the flavor profile of your Creamy Asparagus Chicken Casserole, so stir occasionally until everything is nicely softened and golden.
Step 5: Create the Creamy Sauce
Pour in the chicken broth and heavy cream into the skillet with the sautéed onions and mushrooms. Sprinkle in the kosher salt, black pepper, dried thyme, mayonnaise, dijon mustard, and lemon juice. Let the mixture simmer for about 8-10 minutes until it thickens, stirring regularly to prevent sticking and ensure creamy consistency.
Step 6: Combine and Melt the Cheese
Once the sauce has thickened, stir in your choice of gouda or swiss cheese. Keep stirring until the cheese melts completely and merges into the sauce, enriching your casserole’s creaminess and flavor. This down-to-earth sauce will envelop the chicken and asparagus beautifully.
Step 7: Assemble the Casserole
Pour the creamy cheese sauce evenly over the chicken and asparagus in the casserole dish. Make sure each piece is well coated with the sauce, as this will enhance the overall flavor of the Creamy Asparagus Chicken Casserole. Sprinkle additional cheese on top for a cheesy, crunchy finish.
Step 8: Bake to Perfection
Place the casserole in the preheated oven and bake for about 30 minutes. You’ll know it’s done when it’s bubbling and the chicken reaches an internal temperature of 165°F (74°C). The top should be golden and slightly crispy, providing a perfect contrast to the creamy filling.
Step 9: Garnish and Serve
Once out of the oven, let your Creamy Asparagus Chicken Casserole sit for a few minutes before serving. For a fresh finish, sprinkle with chopped parsley or chives. Pair with a light salad for a complete meal that’s sure to please everyone at the table!

You can prep all the components, including the chicken, steamed asparagus, and creamy sauce, up to 24 hours in advance. Simply cook the chicken and vegetables as instructed, then store them in an airtight container in the fridge.

When it’s time to serve, assemble everything in your greased casserole dish, pour the sauce over, and top with cheese. Bake straight from the fridge for about 35-40 minutes to ensure it’s bubbly and heated through, bringing comforting flavors to your table with minimal effort!
