Ingredients for canned chicken casserole
Pantry staples meet comfort food magic—creamy, cheesy, and packed with celery crown crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Chicken 🍗 | 2 cups | Shredded, drained well |
| Heavy Cream 🥛 | 2 cups | Full-fat for richness |
| All-Purpose Flour 🌾 | ½ cup | For thickening béchamel |
| Milk 🥛 | 2 cups | Whole milk preferred |
| Celery Stalks 🧅 | 4 whole | Thick, cut into 2-inch pieces |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, sharp flavor |
| Gruyère Cheese 🧀 | 1 cup | Shredded, nutty depth |
| Salted Butter 🧈 | ½ cup | Cut into small pieces |
| Garlic Cloves 🧄 | 3 cloves | Minced, for flavor base |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh thyme |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Unsalted Breadcrumbs 🍞 | ½ cup | For celery crowns |
| Olive Oil 🫒 | 2 tbsp | For crisping celery |
The celery crowns are the star here—thick stalks make the best crispy topping. Look for fresh, firm celery at the grocery store, preferably with the outer leaves still intact. I always grab mine from the produce section near the end of the week when it’s freshest. For the cheeses, sharp cheddar and Gruyère give that perfect melty contrast—pre-shredded gets clumpy, so grate your own from a block. The heavy cream matters too; full-fat is non-negotiable for that velvety béchamel. If you’re in a pinch, half-and-half works but won’t be as rich.
No Gruyère? Parmesan or Swiss will work in a pinch, but Gruyère’s nutty flavor is worth hunting down. Running low on celery? Substitute broccoli florets—they crisp up nicely too. The dried thyme can be swapped for fresh at three times the amount, but dried works just fine. For the celery crowns, panko breadcrumbs add extra crunch if you’re feeling fancy. And if you’re prepping ahead, assemble the casserole up to a day early—it tastes even better after sitting overnight.
This casserole reheats beautifully—just cover with foil and bake at 350°F for 20 minutes. Leftovers keep well for 4-5 days in the fridge, and it freezes perfectly for up to 3 months. I like to portion it into individual servings before freezing so I can grab and go. The celery crowns stay crispy even after reheating if you’re not too heavy-handed with the breadcrumbs. Store any extra shredded cheese in an airtight container to keep it fresh.
Why You'll Love This Recipe
- Crispy Crowns, Zero Stress: That breadcrumb-coated celery? It’s the secret weapon—golden, crunchy, and so easy to make you’ll wonder why you ever fried celery separately. Just toss those stalks in breadcrumbs, sear them in olive oil for 5 minutes total, and boom: restaurant-quality texture with zero fuss.
- Cheesy Chicken Overload: The sharp cheddar and nutty Gruyère blend with canned chicken? Chef’s kiss. It’s like a hug in every bite—rich, melty, and just salty enough to make you reach for seconds. Honestly, the béchamel sauce alone is worth the effort, but the cheese? That’s the magic.
- Freezer-Friendly Comfort: Need dinner for a week? This casserole freezes like a dream for up to 3 months. Pop it in the oven straight from the freezer (just add 10 minutes to baking time), and you’ve got a meal that tastes like it was made yesterday. My go-to for busy nights when I’d rather nap than chop veggies.
- Budget Meal, Big Rewards: Canned chicken and whole milk? This isn’t a splurge—it’s a steal. The heavy cream and cheeses make it feel indulgent, but the pantry staples keep costs low. Plus, feeding a crowd? A 9x13 pan means leftovers for days (or lunches for a week). Win-win.
Step-by-step instructions for cheesy celery crown casserole
Here's how to build this rich, comforting casserole with crispy celery crowns and velvety béchamel.
Prepare the Celery Crowns for Crispy Perfection
Trim the bottoms of the 4 whole celery stalks to create flat surfaces. Cut each stalk lengthwise into 4 long strips (about 2 inches wide), creating 16 total strips. This is where texture magic happens—these will become your crispy crowns.
In a small bowl, toss the celery strips with the 0.5 cup unsalted breadcrumbs, ensuring each piece is fully coated. Heat the 2 tbsp olive oil in a large oven-safe skillet over medium-high heat until shimmering. Arrange the breaded celery strips in a single layer, cut-side down, and press gently with a spatula to help them crisp. Cook for 3-4 minutes until golden brown and crispy on the bottom. Flip carefully and crisp the other side for another 2-3 minutes. Remove and set aside on a paper towel-lined plate to keep warm.
Make the Creamy Béchamel Sauce
In a medium saucepan, melt the 0.5 cup salted butter over medium heat until foaming. Add the 3 minced garlic cloves and sauté for 30 seconds until fragrant—don't let it brown or it'll turn bitter. Sprinkle in the 0.5 cup all-purpose flour all at once and whisk vigorously for 1-2 minutes until the mixture forms a smooth paste and turns golden.
Slowly pour in the 2 cups milk while whisking constantly to prevent lumps. Add the 2 cups heavy cream and continue whisking until the sauce thickens enough to coat the back of a spoon, about 5-7 minutes. Stir in the 1 tsp dried thyme, 0.5 tsp ground black pepper, and 1.5 tsp kosher salt. Remove from heat and let it cool slightly while you prepare the remaining components.
Assemble the Casserole Layers
Preheat your oven to 375°F. In a large mixing bowl, combine the 2 cups shredded canned chicken with the 2 cups sharp cheddar cheese and 1 cup gruyère cheese. Stir until the cheeses begin to melt slightly and coat the chicken evenly—this creates that signature creamy, cheesy texture throughout.
Transfer half of the celery crowns to the bottom of a greased 9x13-inch baking dish, arranging them in a single layer. Spread half of the chicken-cheese mixture evenly over the celery. Pour half of the béchamel sauce over the chicken layer, tilting the dish to distribute it evenly. Repeat with the remaining celery crowns, chicken mixture, and béchamel sauce.
Bake to Golden, Bubbly Perfection
Cover the casserole tightly with aluminum foil and bake for 25 minutes. Then remove the foil and bake for another 10-15 minutes until the top is golden brown and bubbly. The edges should be slightly crispy while the center remains creamy—this is your visual cue that the béchamel has thickened properly.
Let the casserole rest for 5 minutes before serving. The creamy sauce will have thickened further while resting, creating that perfect velvety consistency. Garnish with extra black pepper if desired and serve warm with crusty bread to soak up every last drop of that rich, cheesy goodness.
Pro Tips For Making Canned Chicken Casserole
- Press for Crisp: That first flip of the celery crowns is where most people mess up—don’t just toss them. Press each strip down firmly with a spatula while cooking so they make full contact with the pan. I learned this the hard way after getting sad, greasy celery strips instead of golden, crunchy ones.
- Melt the Cheese First: Stir the shredded cheddar and gruyère into the canned chicken until they start melting just a little. This coats every strand of chicken in cheesy goodness, so you don’t end up with dry pockets of protein in your casserole. (Yes, even if it looks weirdly gloppy at first.)
- Whisk Like Your Life Depends on It: When you’re adding the milk and heavy cream to the roux, stop stirring and switch to a whisk. The sauce will thicken faster and smoother—no lumps, no scrambling. I used to rush this part and wondered why my béchamel always ended up grainy.
- Foil First, Then Uncover: The 25-minute covered bake isn’t just about speed—it’s about letting the celery crowns soften slightly while the chicken and cheese heat through. If you skip this, you’ll end up with a sad, undercooked center and a burnt top. Trust the process.
Make-ahead tips for this recipe
Prep Ahead for Effortless Cooking
I start by preparing the celery crowns and béchamel sauce the day before. After crisping the celery strips and cooling them, I store them in an airtight container with a paper towel to absorb any moisture.
The béchamel sauce, once cooled, keeps beautifully in a sealed jar in the fridge—just whisk before using to restore its smooth texture. This saves 30 minutes on the day you cook! 💡
Layering the Night Before
Assemble the casserole layers up to the final baking step—this is where the magic happens. Spread half the chicken-cheese mixture over the celery crowns in your greased dish, then pour half the béchamel sauce.
Cover tightly with foil and refrigerate overnight. The flavors meld perfectly, and the texture improves—trust me, it’s worth the wait. The celery crowns stay crispy even after chilling. ✨
Freezing for Future Meals
For long-term storage, freeze the fully assembled (but uncovered) casserole on a tray for 1 hour to solidify before transferring to a freezer bag. This prevents ice crystals from forming.
When ready to bake, thaw overnight in the fridge, then follow the original baking instructions. The celery crowns might soften slightly but still add delicious crunch. ❄️
Reheating Like a Pro
To revive leftovers, cover the casserole tightly with foil and bake at 350°F for 20 minutes. This gentle heat restores the creamy texture without drying out the cheese.
If reheating from frozen, add 5 minutes to the baking time. I always sprinkle fresh black pepper right before serving to wake up the flavors. 🔥
Portioning for Meal Prep
Divide the casserole into individual portions before freezing—this makes grab-and-go meals a breeze. Label each container with the date so you can enjoy it within 3 months. The celery crowns stay crispier when reheated from smaller portions, so this trick keeps every bite satisfying. 💪
Cheese Prep Shortcut
Shred your own cheeses (cheddar and Gruyère) the night before and store them in a sealed bag with a parchment paper liner to absorb moisture. This prevents clumping and saves time during assembly.
I also pre-mix the chicken and cheese in a bowl, so all I need to do is spread it over the celery crowns. Small steps make a big difference! 🍗
Nutrition facts
Frequently asked questions
Can I use canned tuna instead of chicken in this recipe?
Canned tuna works perfectly as a protein swap. Drain and flake it well, then mix it with the cheeses just like you would with the chicken. The texture will be slightly denser, but the creamy béchamel and crispy celery crowns will still shine. Just add a pinch of extra salt if your tuna is lightly seasoned.
Why does my béchamel sauce get lumpy? How can I fix it?
Lumpy béchamel usually happens when milk is added too quickly or whisked too slowly. To fix it, strain the sauce through a fine-mesh sieve or blend it briefly with an immersion blender. For prevention, always whisk constantly over medium heat and avoid letting it bubble vigorously. If you're in a pinch, blend the sauce with a hand mixer until smooth.
How do I keep the celery crowns crispy after baking?
Crispy celery crowns are all about prep and timing! After crisping them in the skillet, let them cool completely on a wire rack instead of a plate to prevent steam. Store them in an airtight container with a paper towel to absorb moisture. When reheating, place them under the broiler for 1-2 minutes to revive their crunch.
Can I make this casserole ahead of time?
Yes! Assemble the casserole up to the final baking step and refrigerate it covered for up to 24 hours. The flavors deepen overnight, and the texture improves. When ready to bake, follow the original instructions, but add 5-10 minutes to the baking time since it starts at room temperature. It reheats beautifully and tastes even better the next day!
