Ingredients
Equipment
Method
- Preheat your oven to 375°F (190°C). If your chicken isn’t already cooked, prepare it now. You can boil chicken breasts for 15-20 minutes until cooked through, then shred or dice them. Set aside.
- Lightly grease a 9×13 inch baking dish.
- In a large skillet or Dutch oven, melt the 4 tablespoons of butter over medium heat.
- Add the diced yellow onion and celery to the skillet. Sauté for 5-7 minutes, or until the vegetables are softened and translucent.
- Sprinkle the all-purpose flour over the softened vegetables. Cook, stirring constantly, for 1-2 minutes to create a roux. This helps cook out the raw flour taste.
- Gradually whisk in the chicken broth, then the whole milk, and finally the heavy cream. Continue whisking to prevent lumps until the sauce is smooth. Bring the mixture to a gentle simmer, stirring frequently, until it thickens, about 5-8 minutes.
- Remove the skillet from the heat. Stir in the dried thyme, crushed dried rosemary, salt, and black pepper. Taste and adjust seasonings as needed.
- Add the shredded cooked chicken, frozen peas, and frozen diced carrots to the creamy sauce in the skillet. Stir gently to combine everything thoroughly, ensuring the chicken and vegetables are well coated.
- Pour the chicken and vegetable mixture evenly into the prepared 9×13 inch baking dish.
- In a small bowl, combine the crushed Ritz crackers, shredded sharp cheddar cheese, and 2 tablespoons of melted butter. Stir until the cracker crumbs are evenly coated.
- Sprinkle the cracker topping evenly over the chicken mixture in the baking dish.
- Bake the casserole in the preheated oven for 30-35 minutes, or until the filling is bubbly around the edges and the cracker topping is golden brown and crispy.
- Remove from oven and let stand for 5-10 minutes before serving. This allows the casserole to set slightly and makes for easier serving.
Notes
When I’m making a comforting dish like Chicken Casserole, I’ve picked up a few tricks over the years to ensure it turns out perfectly every time.
My Secret Trick: I always use a mix of leftover rotisserie chicken and some freshly sautéed chicken for an extra layer of flavor and texture. The rotisserie chicken adds depth, while the freshly cooked bits keep it moist and tender.
Don’t rush the sauce! Whisking the flour into the melted butter and letting it cook for a minute or two (creating a roux) is key to a smooth, lump-free sauce that thickens beautifully without a raw flour taste.
For that extra golden crunch on top, I like to gently crush the Ritz crackers by hand rather than in a food processor. This creates varied crumb sizes, which leads to a more interesting texture once baked.
Always let your Chicken Casserole rest for 5-10 minutes after it comes out of the oven. This allows the sauce to set slightly, making it easier to serve and preventing it from being too runny.
Fun Variations for Chicken Casserole
One of the things I adore about a good Chicken Casserole is how wonderfully adaptable it is! It’s like a blank canvas waiting for your creative touch. Here are a few ideas that my friends and family adore:
Veggie Boost
My sister always asks me to add in some sautéed mushrooms or a handful of fresh spinach when I make this. For a twist, try adding some roasted butternut squash or sweet potato cubes for extra sweetness and nutrients. Just make sure they are mostly cooked before adding them to the casserole.
Spice It Up!
If you like a little kick, a pinch of red pepper flakes in the creamy sauce can really liven things up. Or, for a smokier flavor, a dash of smoked paprika works wonders with the chicken.
Cheesy Topping Swaps
While sharp cheddar is a classic, don’t be afraid to experiment! A friend loves when I mix in a little Parmesan or even a touch of smoked gouda with the cheddar for a more complex, nutty flavor in the topping.
What to Serve With Chicken Casserole
This delightful Chicken Casserole is a hearty meal all on its own, but sometimes, a little something extra can make the experience even more special. When I’m thinking about what to pair with it, I lean towards things that offer a lovely contrast in texture or a fresh, bright flavor.
I love serving this creamy chicken casserole with a simple green salad, tossed with a light vinaigrette. The crisp freshness of the greens really balances the richness of the casserole. Another wonderful pairing is some warm, crusty bread to soak up every last bit of that delicious sauce. My mom always had a side of steamed green beans or asparagus, lightly buttered, which also complements the flavors beautifully. If you’re short on time, a quick side of roasted broccoli florets tossed with garlic and olive oil is always a winner!
How to Store Chicken Casserole
Having leftovers of this comforting Chicken Casserole is truly a treat! To keep it tasting as fresh and delicious as possible, proper storage is key.
Refrigerator Storage
Once cooled to room temperature, transfer any leftover Chicken Casserole to an airtight container. It will keep beautifully in the refrigerator for up to 3-4 days. I like to press a piece of plastic wrap directly onto the surface before sealing the container, which helps prevent it from drying out.
Freezing Tips
For longer storage, this casserole freezes wonderfully. Again, once cooled, transfer portions to freezer-safe containers. It can be frozen for up to 2-3 months. When you’re ready to enjoy, thaw it in the refrigerator overnight.
Reheating for Best Results
To reheat, you can warm individual portions in the microwave until heated through, or for a whole casserole, cover it loosely with foil and bake in a preheated oven at 325°F (160°C) until warmed through, usually about 20-30 minutes. My personal tip is to add a splash of milk or broth to the sauce before reheating if it seems a little dry, ensuring that creamy texture is fully revived.
Nutritional Benefits
While this Chicken Casserole is undeniably a comfort food, it also packs in some wholesome goodness! With lean protein from the chicken and a medley of essential vitamins from the peas and carrots, it’s a satisfying meal that nourishes the body as much as it comforts the soul. It’s a treat that’s both satisfying and helps you enjoy your veggies!
FAQs
Faq 1
Can I make this chicken casserole ahead of time?
Absolutely! You can assemble the entire casserole, including the topping, up to a day in advance. Cover it tightly and refrigerate. Just add an extra 10-15 minutes to the baking time when you’re ready to cook it straight from the fridge.
Faq 2
What kind of chicken is best for this recipe?
Cooked chicken is key! You can use leftover roasted or rotisserie chicken, or simply boil or bake some boneless, skinless chicken breasts and shred or dice them. The important thing is that it’s already cooked before adding it to your delicious chicken casserole.
Faq 3
Can I use different crackers for the topping?
Yes, you can! While Ritz crackers provide that iconic buttery flavor, you could also use crushed butter crackers, saltines, or even a mix of breadcrumbs and Parmesan cheese for a different crunch on your creamy chicken casserole.
Faq 4
Why is my casserole sauce too thin or too thick?
The consistency of your sauce can depend on how long you cook the roux or the exact measurements of your liquids. If it’s too thin, simmer gently to reduce. If too thick, whisk in a little more milk until it reaches your desired creamy consistency for your hearty chicken casserole.
