Brooke’s Tip:  Meal prep ahead of time for this recipe by making shredded chicken in your slow cooker and freeze or refrigerate the shredded chicken until ready to use which will save you time on busy weeknights.

For the sauce: Over medium heat, melt the butter in a large saucepan. Whisk in the flour until smooth. Continue to whisk the mixture while slowly adding milk — stir until sauce thickens, about 10 minutes, whisking continuously.

Time Saving Tip: To make the thickening process go faster, heat milk in the microwave until it boils (about 2-3 minutes). Then slowly add to the saucepan, whisking as you pour.

Add lemon juice, Dijon mustard, paprika, and pepper. Bring sauce to a low simmer again, whisk continuously. Once it has reached the desired thickness, remove from heat and pour sauce evenly over the casserole.

For the topping: In a small saucepan, melt the butter and stir in Panko breadcrumbs, garlic, parsley, and pepper. Sprinkle topping mixture over the top of the casserole. Lightly mist top of casserole with nonstick cooking spray. Bake for 35 minutes until topping is golden brown.

KETO VERSION:  Instead of whole wheat flour in the sauce, sub in almond flour or xantham gum to thicken.  For the crumb topping, use ground pork rinds for crunch without carbs.
