Step‑by‑Step Instructions for Creamy Asparagus Chicken Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C) to prepare for baking the creamy asparagus chicken casserole. This temperature will ensure a bubbly and golden result. While the oven heats up, gather all your ingredients to streamline the cooking process.
Step 2: Prepare the Asparagus
In a microwave-safe dish, steam the asparagus by adding ¼ cup of water and covering it with plastic wrap. Microwave on high for about 3 minutes or until tender but still bright green. Once done, drain any excess water and set the asparagus aside, ready to add to the casserole.
Step 3: Sauté the Chicken
In a large skillet, melt 2 tablespoons of butter over medium-high heat. Add 1 inch pieces of boneless skinless chicken breasts to the skillet and sauté for approximately 6 minutes, or until the chicken is golden brown. Once cooked, transfer the chicken to a greased baking dish and layer the steamed asparagus on top.
Step 4: Cook the Onions and Mushrooms
Using the same skillet, add chopped onions and sliced mushrooms, sautéing them for about 4–5 minutes until tender and fragrant. Stir occasionally to prevent sticking, and once softened, proceed to the next step. This will add a depth of flavor to your creamy asparagus chicken casserole.
Step 5: Make the Creamy Sauce
To the skillet with onions and mushrooms, add 1 cup of chicken broth, 1 cup of heavy cream, salt, pepper, dried thyme, mayonnaise, Dijon mustard, and fresh lemon juice. Bring this mixture to a simmer, stirring frequently for about 5–7 minutes until it thickens slightly. This sauce is the heart of your casserole, enhancing the dish’s creaminess.
Step 6: Combine and Add Cheese
Pour the creamy sauce over the chicken and asparagus in the baking dish, mixing gently to ensure everything is well-coated. Top generously with shredded gouda or Swiss cheese, as well as grated Parmesan for added flavor. The cheese will create a deliciously gooey topping once baked.
Step 7: Bake to Perfection
Place the baking dish in your preheated oven and bake for 30 minutes. Keep an eye on the casserole; it should be bubbling and golden on top, and the chicken should reach an internal temperature of 165°F (74°C). Your creamy asparagus chicken casserole is now ready to be served!
