1 pound boneless chicken breasts (I used boneless tenders)
2 tbsp butter
1.5 tbsp flour
1 cup milk
3 tbsp sour cream
3 tbsp horseradish
1/2 tsp Dijon mustard
a few dashes each of cayenne pepper (optional)
salt and pepper
Melt butter in a pan over medium heat.
Add flour and stir. Whisk in milk, bring to a boil, then simmer about 3 minutes.
Stir in the horseradish, sour cream, Dijon, and spices. Stir/simmer for a few minutes.
Pour about 1/2 of the sauce over chicken in a baking dish (the rest is good heated up and served over your side - rice, plain potatoes, noodles, etc).
Bake on 350 for approx 20-25 min til chicken is done. Turn the broiler on for 4-5 minutes to get the sauce nice and bubbly.
