• 1/2 tsp dried thyme

• 1 tbsp dijon mustard
• 1 tbsp lemon juice

How To Make Creamy Chicken and Asparagus Bake

Preheat oven to 375 degrees. In a 12" skillet, melt butter over medium-high heat. (See image 1 below)

Add chicken to the pan and cook for 6 minutes. Turn chicken after 3 to 4 minutes or when it begins to brown. (See image 2)

Remove chicken and place in a casserole dish. Top with the steamed asparagus. Cover and keep warm. (See image 3)

Add onions and mushrooms to skillet. Sautee until tender. (See image 4)

Reduce heat to medium and add chicken broth, cream, salt, pepper, thyme, dijon, mayonnaise, and lemon juice. Whisk together and bring to a simmer. (See image 5 below)

Cook until sauce reduces and starts to thicken about 8 to 10 minutes. Stir frequently. (See image 6). (Optional) stir in xanthan gum mixed with 1 tsp olive oil to further thicken sauce if needed, stir.

Add cheeses then stir until melted. Pour the mixture over the casserole). (See image 7)

Sprinkle with remaining cheeses. (See image 8) Bake for 30 minutes until bubbly and chicken is done.

Helpful Tips

• The chicken can be cut into bite-size pieces and then cooked in the skillet.
• Make this a one-pan casserole by using an ovenproof skillet. Finish the sauce then add the chicken and asparagus back to the pan. Stir, making sure sauce is covering the chicken. Top with cheese and then bake.  
• You can add 1/2 cup sour cream if you want more creaminess too! You will have to adjust your salt and pepper to taste. 
• When adding xanthan gum to a dish, dissolve it in a little olive oil (1 tsp) before adding so it won't clump. Use xanthan gum sparingly as A little goes a long way! I turned a dish into a gummy mess once, so I know first hand! In this recipe, start with 1/2 tsp only.
