Mushrooms: Chestnut (cremini) mushrooms are recommended, but white button mushrooms can be substituted.
Chicken: Cut the chicken into uniform bite-sized pieces for even cooking.
Mustard: Wholegrain mustard adds texture and tangy flavor. You can substitute Dijon mustard if preferred.
Paprika: Sweet smoked paprika adds a lovely smoky depth. Regular sweet paprika can be used if smoked is unavailable.
Soured Cream: Use room-temperature soured cream to help prevent curdling when adding it to the warm sauce. Do not let the sauce boil rapidly after adding the sour cream. Reduced-fat sour cream can be used.
Herbs: Fresh tarragon or parsley adds brightness. Use whichever you prefer or have on hand.
Serving Suggestions: Serve this Chicken Stroganoff traditionally over egg noodles, rice, or mashed potatoes.
Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently.
