Ingredients for canned chicken casserole
Pantry staples and canned chicken come together for creamy, comforting casserole magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Chicken Breast 🍗 | 14 oz | Drained, no salt added preferred |
| Cream of Mushroom Soup 🍄 | 1 can | 10.5 oz can, condensed |
| Milk 🥛 | ½ cup | Whole or 2% for creaminess |
| Celery 🧅 | 1 ½ cups | Diced small, fresh or frozen |
| Yellow Onion 🧅 | ½ cup | Finely chopped, fresh or frozen |
| Ritz Crackers 🍞 | 1 ½ cups | Crushed, original flavor |
| Butter 🧈 | ½ cup | Melted, unsalted preferred |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening sauce |
| Salt 🧂 | ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For extra flavor |
| Frozen Peas 🌽 | ½ cup | Optional for extra veggies |
The canned chicken is the star here, so look for no-salt-added varieties—it keeps the flavor balanced without overpowering. I always grab the Starkist or Chicken of the Sea brands at Walmart or Kroger since they're reliable and affordable. Fresh celery and onion make all the difference, but frozen works in a pinch (just thaw and drain well). For the Ritz crackers, stick to the original flavor—any seasoned varieties can clash with the creamy sauce. If you're short on time, the frozen veggie mix with celery and onion saves chopping.
No cream of mushroom soup? Cream of celery soup works great, or even a mix of milk and cream with a bouillon cube. Short on milk? Evaporated milk or half-and-half adds richness without thinning the sauce too much. The flour is key for thickening—all-purpose works fine, but if you've got cornstarch, use half the amount for a glossier finish. For extra flavor, add a dash of Worcestershire sauce or hot sauce to the mix. The garlic powder can be swapped for fresh minced garlic if you're feeling fancy—just use half a teaspoon.
This casserole tastes even better the next day, so make a double batch if you can. Keeps in the fridge for 4-5 days covered, or freeze for 3 months in airtight containers. I like to reheat portions in the microwave for 2-3 minutes, then broil for 2 minutes to crisp the cracker topping. The leftovers reheat beautifully—just add a splash of milk to loosen if it gets too thick. Store any extra crushed crackers in a sealed bag for up to 2 weeks.

Step-by-step instructions for creamy celery casserole
This one-pan wonder delivers rich, creamy comfort in under 45 minutes.
Prepare the Crunchy Topping
Preheat your oven to 375°F. In a medium bowl, crush the 1½ cups Ritz Crackers into coarse crumbs using your hands or a rolling pin. The texture should be uneven—some larger pieces add delightful crunch. Stir in the 0.5 tsp garlic powder, 0.5 tsp salt, and 0.25 tsp black pepper until evenly distributed. This seasoned crumb topping will create that signature crispy contrast you crave.
Set aside the cracker mixture while you prepare the filling. The crackers will soften slightly during baking, but their edges will stay perfectly crisp—this is the secret to that satisfying crunch in every bite. If you're feeling fancy, you can melt ¼ cup of the butter with the crackers, but I prefer keeping them dry for maximum texture.
Build the Creamy Filling
In a large mixing bowl, combine the drained 14 oz canned chicken breast, 1 can cream of mushroom soup, 0.5 cup milk, 1.5 cups diced celery, 0.5 cup finely chopped yellow onion, and 0.5 cup frozen peas. Stir gently but thoroughly to distribute all ingredients evenly. The peas will stay frozen at first, but they'll thaw and soften beautifully during baking.
In a separate small bowl, whisk together the 2 tbsp all-purpose flour and remaining ¼ cup melted butter. Slowly pour this mixture into the chicken filling while stirring constantly. This creates a natural thickener that will give your casserole that luscious, creamy consistency without needing extra cream. The flour-butter combo also adds a subtle richness that balances the savory flavors.
Assemble and Bake to Perfection
Lightly grease a 9x13-inch baking dish (or similar size) with butter or cooking spray. Spread the chicken mixture evenly across the bottom, pressing down gently to create an even layer. This helps the filling cook uniformly and prevents any dry spots from forming at the edges.
Sprinkle the cracker mixture evenly over the top, pressing down lightly with your fingers to help it adhere. You want the crackers to cover the entire surface but not be packed too tightly—this ensures they crisp up properly. Bake uncovered for 30 minutes, then tent loosely with aluminum foil and continue baking for another 10-15 minutes until the top is golden brown and the filling is bubbling at the edges.
Rest and Serve Warm
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This resting period allows the filling to set slightly, making it easier to slice and serve. The cracker topping will stay warm and crispy while the creamy filling cools just enough to be safe to eat.
Cut into squares and serve immediately. The contrast of the warm, creamy chicken filling with the crispy cracker topping is what makes this dish so irresistible. Each bite delivers that perfect combination of textures and flavors—savory chicken, creamy mushroom sauce, and that satisfying crunch from the crackers.
Pro Tips For Making Canned Chicken Casserole
- DRAIN AND RINSE CHICKEN: That salty canned chicken? Drain it first, then hit it with a quick cold water rinse—even if the label says “low-sodium.” I learned this the hard way when my first batch tasted like a salt lick. Pat it dry afterward so the milk doesn’t turn into soup.
- SAUTÉ ONIONS UNTIL GOLDEN: Skip the “soften” step—cook those onions until they’re actually golden, not just translucent. Five minutes over medium heat with a pinch of salt makes a real difference. My grandmother swore by this, and she was right: it cuts through the creaminess of the soup.
- STIR IN MILK LAST: Mix the soup and milk first, then fold in the chicken and veggies. Adding milk too early turns your casserole into a watery mess. I was skeptical until I tried it—now I never skip this step.
- BAKE UNTIL BUBBLY AND SET: Don’t pull it out when it looks done—wait until the top is bubbling, the edges are set, and a toothpick comes out clean. I used to eyeball it and end up with a sad, gummy center. Crank the oven to 375°F if yours runs hot, and give it 10-15 minutes longer than the recipe says.
Flavor customization for canned chicken casserole
Spicy Kick
Add 1-2 tablespoons of hot sauce (like Crystal or Tabasco) or ½ teaspoon cayenne pepper to the filling for instant heat. For smoky depth, stir in ½ teaspoon smoked paprika or a dash of Cholula hot sauce.
I love adding a pinch of red pepper flakes to the cracker topping for extra crunch and spice. Serve with cool ranch or Greek yogurt dip to balance the heat. 🌶️
Cheesy Twist
Sprinkle 1 cup shredded cheddar or Monterey Jack over the cracker topping before baking for a melty, gooey finish. For a richer version, mix ½ cup cream cheese into the filling before assembling.
I also like adding ¼ cup grated Parmesan to the cracker mixture for a savory, umami boost. Use Kraft shredded cheese for convenience or sharp cheddar for bold flavor.
Vegetable Boost
Incorporate 1 cup frozen mixed vegetables (like carrots, corn, or green beans) into the filling for added nutrition. Fresh spinach or kale works too—just wilt it first by sautéing with the onions.
For a Southern-inspired twist, add ½ cup diced bell peppers and a pinch of Old Bay seasoning. I often use Birds Eye frozen veggie mix for convenience and color.
Herb Infusion
Brighten the flavor with fresh herbs like ¼ cup chopped parsley or chives stirred into the filling. Dried herbs work too—try 1 teaspoon dried thyme or oregano for a Mediterranean touch.
For a fresh finish, sprinkle 2 tablespoons chopped fresh dill over the cracker topping before baking. I keep Penzeys dried herbs on hand for quick flavor enhancements.
Crunch Alternatives
Swap Ritz crackers for crushed potato chips (like Kettle Brand) for a salty crunch or panko breadcrumbs for a lighter texture. For a gluten-free option, use crushed gluten-free crackers or almond flour.
I’ve also topped with crushed tortilla chips for a Tex-Mex vibe. Toast the topping for 2-3 minutes before adding to the casserole for extra crispiness.
Protein Swaps
Use canned tuna or salmon instead of chicken for a seafood twist—just reduce the milk to ¼ cup to prevent thinning. For a vegetarian version, replace the chicken with 1 can of chickpeas (drained) and add 1 teaspoon garlic powder for depth.
I’ve also used rotisserie chicken for extra moisture and texture. Always drain and pat dry canned proteins to avoid a soggy casserole.

Frequently asked questions
Can I make this casserole ahead of time?
This casserole actually tastes even better the next day. Assemble it as directed, then refrigerate uncovered for 2-4 hours before baking. For make-ahead meals, prepare the filling and topping separately, then combine and bake when ready. Store leftovers in an airtight container for up to 5 days in the fridge or freeze for 3 months. Reheat covered in the oven at 350°F for 15-20 minutes to restore crispiness.
What if I don't have Ritz crackers for the topping?
No problem! Try these alternatives: crushed potato chips (like Kettle Brand) for salty crunch, panko breadcrumbs for lighter texture, or gluten-free crackers if needed. For extra flavor, toast your alternative topping with 1 tbsp butter and ½ tsp garlic powder for 2-3 minutes before adding to the casserole. The key is using something that will crisp up during baking.
Why did my casserole turn out watery?
Watery results usually happen when the canned chicken isn't drained well or the milk quantity is too high. Always drain and pat dry your canned chicken thoroughly, and consider reducing the milk to ¼ cup instead of ½ cup. Another fix is to let the filling sit for 10 minutes before baking to thicken naturally. For extra insurance, stir in 1 extra tablespoon of flour with the butter mixture.
Can I use fresh chicken instead of canned?
Yes, but you'll need to adjust the cooking time. Use 1½ cups cooked, shredded chicken breast (about 2 boneless breasts) instead of canned. Cook the chicken separately until fully done (165°F internal temp), then shred before mixing with other ingredients. Fresh chicken adds more moisture, so you may want to reduce the milk to ¼ cup and increase the flour to 3 tbsp for proper thickening.
What are the best sides to serve with this casserole?
This creamy casserole pairs beautifully with simple, fresh sides. Try a crisp green salad with vinaigrette, steamed broccoli with lemon, or warm dinner rolls. For a Southern touch, serve with cornbread or buttered biscuits. The cracker topping makes it satisfying on its own, but the contrast with something light and fresh balances the richness perfectly.
