What Kind of Chicken Works Best?
This recipe is very flexible:
- Rotisserie chicken is the easiest option and adds great flavor.
- Chicken breast is lean and mild, absorbing the ranch dressing beautifully.
- Chicken thighs are juicier and slightly richer—perfect if you prefer dark meat.
- A mix of breast and thigh meat works wonderfully too.
You’ll need about 4 cups of cooked chicken, which usually equals one large rotisserie chicken plus a little extra.
Can I Use Frozen Vegetables?
Yes—frozen broccoli or spinach works perfectly.
- Frozen spinach: Thaw completely and squeeze out as much liquid as possible.
- Frozen broccoli: Thaw and drain well. Skip boiling since it’s already blanched.
Fresh vegetables offer a slightly firmer texture, but frozen saves time and still tastes great.
Make-Ahead & Freezer Instructions
