Ingredient Notes

- With rotisserie chicken being a convenient option, you can also use any leftover cooked chicken to achieve the same result. You’ll require approximately two pounds or around four cups of boneless, skinless chicken to achieve the desired result.
- You don’t need to thaw these frozen vegetables before baking them; they’ll cook evenly and thoroughly in the oven. For a burst of freshness, substitute with broccoli and steam its florets for precisely seven minutes to achieve the perfect tender consistency before layering.
- While we don’t endorse particular brands, you’re encouraged to select the stuffing that’s a staple in your household.
- A suitable replacement for sour cream is Greek yogurt, which can be used in equal quantities.
- While sharp cheddar is the preferred choice, mild cheddar or alternative options such as Gruyère or Monterey Jack can also yield satisfactory results.
- We suggest pairing your casserole with Ritz crackers as the topping of choice; however, traditional breadcrumbs are a suitable alternative should you desire.
- If you’re not a fan of mayonnaise, consider substituting with an equal measure of plain Greek yogurt or a generous helping of sour cream to achieve a similar creamy texture.
- To prepare this recipe, you’ll require the fresh juice of two average-sized lemons. When substituting for lemons, consider using bottled lemon juice as a fallback option, though nothing beats the zesty, vibrant taste of freshly squeezed lemon juice if feasible.

Making the Sauce
The crowning jewel of this casserole is undoubtedly its rich, velvety sauce, expertly balanced by the subtle brightness of lemon zest and the tangy depth of sour cream. While some casseroles rely on canned creamed soup for convenience, crafting your own sauce is a game-changer – the distinct flavors and textures will forever change your perception of premade alternatives. While the sauce’s simplicity makes it an accessible recipe, a more descriptive approach might read: With minimal effort required, this delectable sauce comes together seamlessly as you simply stir and warm it gently over moderate heat. That’s it!

Make Ahead Option
This meal’s convenience makes it an excellent choice for individuals seeking to prepare in advance for a hectic day ahead. This casserole can be prepared up to 24 hours in advance and refrigerated until baking, allowing for added convenience in meal planning. Using this method will require a slightly longer baking time, approximately one hour in total.
To gain an extra edge, consider freezing your casserole before baking for a head-start on mealtime. To preserve the casserole, cover it with multiple layers of plastic wrap or aluminum foil, allowing you to safely store it in your freezer for a duration of up to three months. To achieve optimal results, allow the dish to thaw in the refrigerator overnight prior to baking. Once baked, ensure it is covered with foil during its initial 30-minute period in the oven. With the foil removed, continue cooking the dish uncovered for an additional 45 to 55 minutes.
