Advanced Techniques for Perfecting Your Nixon Chicken
While Nixon Chicken is delicious as is, there are a few advanced techniques you can use to elevate this already fantastic casserole.
Adding Crunch
For extra texture, consider topping the casserole with breadcrumbs or crushed crackers before baking. Panko breadcrumbs or even crumbled Ritz crackers add a delightful crunch that contrasts beautifully with the creamy filling.
Flavor Variations
Add some extra seasoning to suit your preferences! A teaspoon of garlic powder, paprika, or Italian seasoning can deepen the flavor of the casserole. For a spicy twist, try adding diced jalapeños or a dash of hot sauce.
Add More Veggies
You can also customize this casserole by adding other vegetables such as sliced mushrooms, bell peppers, or carrots. Roasted vegetables work great as a mix-in for additional flavor and nutrition.
Switch Up the Protein
While rotisserie chicken is quick and easy, you can use cooked turkey or even ground beef or sausage for a different protein option. If you prefer a vegetarian version, substitute the chicken with a plant-based protein or tofu.

Storage, Shelf Life, and Maintenance Tips
Storing Leftovers
Nixon Chicken can be stored in the refrigerator for up to 3-4 days. Make sure to let it cool down to room temperature before covering it with plastic wrap or transferring it to an airtight container.
Freezing for Later
This casserole freezes really well! Once it’s cooled, wrap the casserole tightly in plastic wrap and aluminum foil. Store it in the freezer for up to 3 months. When you’re ready to enjoy it, simply thaw it overnight in the fridge and reheat it in the oven at 350°F (175°C) for 20-30 minutes, until it’s heated through.
Reheating Instructions
To reheat, place the leftover casserole in a preheated oven at 350°F (175°C) and bake for 20-25 minutes, or until heated through. You can also reheat individual portions in the microwave for 1-2 minutes, depending on your microwave’s wattage.

Dietary Adaptations and Substitutions
Nixon Chicken is highly adaptable for various dietary needs. Here are a few substitutions you can try:
Gluten-Free
This recipe is naturally gluten-free, but be sure to use gluten-free mayonnaise and check that your cream of mushroom soup is gluten-free as well. You can also opt for gluten-free breadcrumbs if adding a crunchy topping.
Dairy-Free
For a dairy-free version, swap the mayonnaise for a dairy-free mayonnaise alternative and use dairy-free cheese (such as Daiya or Violife). You can also use coconut milk or another dairy-free substitute for the cream of mushroom soup.
Low-Carb/Keto
For a low-carb or keto-friendly version, use cauliflower florets instead of broccoli, or substitute the mayonnaise with an avocado-based dressing. Make sure to use full-fat, low-carb ingredients for a satisfying, low-carb meal.
Vegetarian
If you’re looking for a vegetarian version, simply replace the chicken with cooked quinoa or a plant-based protein like tempeh or tofu. Make sure to choose a vegetarian-friendly cream of mushroom soup as well.

FAQs About The Recipe
Can I use fresh broccoli instead of frozen?
Yes, fresh broccoli works perfectly in this casserole! Steam it until tender, and use it just like you would use the frozen broccoli.
Can I use a different type of cheese?
Absolutely! If you prefer a different cheese, you can swap cheddar for mozzarella, Swiss, or even Monterey Jack. Just keep in mind that different cheeses will melt differently and alter the flavor of the dish slightly.
Can I prepare this casserole ahead of time?
Yes, you can prep the casserole ahead of time! Simply assemble the casserole (but don’t bake it), cover it, and refrigerate it for up to 24 hours. When you’re ready to bake, pop it into the oven as directed, adding a few extra minutes to the cooking time if needed.
Can I make this without mayonnaise?
If you’re not a fan of mayonnaise, you can substitute it with sour cream or plain Greek yogurt. Both will provide a creamy texture and tangy flavor that complements the dish.
