PRO TIPS AND VARIATIONS

For the creamiest sauce, use room temperature sour cream and add it during the last few minutes of cooking. This prevents curdling and ensures a smooth, velvety texture.

For extra flavor, add a tablespoon of Dijon mustard to the creamy sauce. It adds a subtle tang that complements the ham and Swiss cheese beautifully.

This recipe is highly adaptable. Substitute the chicken with turkey or rotisserie chicken for a shortcut. For a vegetarian version, omit the chicken and ham and add extra vegetables like mushrooms, broccoli, and cauliflower.

For a spicier version, add a pinch of cayenne pepper or use pepper jack cheese instead of mozzarella.

Leftovers store well in the refrigerator for up to four days. Reheat in the oven or microwave. The dish also freezes well for up to three months.
