Name: Overnight Chicken and Waffles Casserole Recipe
Prep time: 15 min
Cook time: 35 min
Total time: 50 min
Ingredients: 8 frozen buttermilk waffles; 2 cups diced cooked chicken; 4 large eggs; 1 ½ cups whole milk; ¼ cup maple syrup; 3 tbsp unsalted butter, melted; 1 tsp vanilla extract; ½ tsp ground cinnamon; ¼ tsp fine sea salt; Chopped pecans, for serving (optional)

This Overnight Chicken and Waffles Casserole takes the diner classic and turns it into a lazy brunch bake. Everything soaks together while you sleep, so all you have to do in the morning is turn on the oven.

The waffles soften into a sweet, cinnamon-scented custard while the chicken stays juicy and savory. Crispy golden edges meet tender middles, and a final drizzle of maple syrup ties it all together. It’s the kind of dish that makes a random Saturday feel like a holiday.

Why This Casserole Works

I keep coming back to this one because it gives you all the things you love about chicken and waffles without any of the last-minute frying or fiddling. The oven does the heavy lifting, and the overnight soak means you wake up to a dish that just needs to bake.

The texture is what gets me: soft, almost bread-pudding-like inside with shatteringly crisp bits on top. Every bite hits sweet, salty, and savory in the best way.

Ingredients

8 frozen buttermilk waffles: the thick kind, like Eggo or Kodiak Cakes, work well. Thin waffles can turn mushy.
2 cups diced cooked chicken: rotisserie or leftover roasted chicken is ideal. Pat it dry if it seems moist.
4 large eggs
1 ½ cups whole milk: 2% works too, but whole milk gives the richest custard.
¼ cup maple syrup: use real maple syrup, not pancake syrup, for the best flavor.
3 tbsp unsalted butter, melted
1 tsp vanilla extract
½ tsp ground cinnamon
¼ tsp fine sea salt
Chopped pecans, for serving (optional)

Variations / Substitutions

Swap the protein: cooked turkey, browned breakfast sausage, or plant-based strips all work.
Gluten-free waffles: use your favorite thick gluten-free brand; the soak time stays the same.
Add cheese: fold ½ cup shredded sharp cheddar into the chicken for a savory boost.
Make it savory: reduce maple syrup to 2 tbsp, add ½ tsp black pepper and 1 tsp rosemary.

How To Make Overnight Chicken and Waffles Casserole

Step 1: Tear the Waffles

Heat the oven to 350°F (175°C). Butter a 9×13-inch baking dish. Tear each frozen waffle into roughly 1-inch chunks directly into the dish. No need to thaw them.

The uneven pieces give you both soft and crispy textures after baking. Don’t worry about uniform sizes; the raggedy bits create those golden, crunchy edges later.

Step 2: Whisk the Custard

In a large bowl, whisk the 4 eggs, 1 ½ cups milk, ¼ cup maple syrup, 3 tbsp melted butter, 1 tsp vanilla, ½ tsp cinnamon, and ¼ tsp salt. Whisk for about 2 minutes, until the mixture is smooth and there are no clumps of cinnamon floating on top.

The custard will look thin at this stage, but it thickens as it soaks into the waffles overnight.

Step 3: Layer the Casserole

Scatter the 2 cups diced chicken over the waffle pieces, then pour the custard evenly over everything. Use a spatula or your hands to gently press the waffles down into the liquid, making sure all the pieces get coated.

The dish will look soupy, and that’s exactly right. The waffles absorb most of the liquid as they chill.

Step 4: Chill and Soak

Cover the dish tightly with plastic wrap or a lid and refrigerate for at least 4 hours, but overnight (8 to 12 hours) is ideal. This slow soak is what gives the casserole its soft, pudding-like center.

If you pull it out in the morning, you’ll notice the waffle chunks have puffed up and sucked up nearly all the custard. That’s your cue it’s ready for the oven.

Step 5: Slice and Serve Warm

Uncover the dish and bake on the middle rack for 35 to 40 minutes, until the top is deeply golden and the custard is set (it should no longer jiggle in the center). Let the casserole cool for 5 minutes on the counter while you pour a cup of coffee.

Slice into 6 squares and serve warm, with an extra drizzle of maple syrup and a handful of chopped pecans if you like. The contrast of sweet syrup, juicy chicken, and custardy waffle chunks is exactly why this dish works.

A Few Notes Before You Start

Thick waffles hold their shape: thin, flimsy waffles disintegrate during the soak. Belgian-style frozen waffles are your best bet.
Rotisserie chicken is a shortcut: pull the meat from a store-bought bird and season it lightly with salt and pepper if it’s unseasoned.
Pat the chicken dry: if the chicken is very moist, blot it with paper towels so it doesn’t water down the custard.
Don’t skip the soak: the minimum 4 hours in the fridge lets the flavors meld and gives you that soft, bread-pudding texture. Skipping it leads to a drier, less cohesive casserole.

Bake times by dish size:

Dish Size	Bake Time
9×13-inch	35-40 mins
Deep 8×8-inch	40-45 mins
4-inch mini skillets	25-30 mins

Storing and Reheating Leftovers

Refrigerate: store leftovers in an airtight container for up to 3 days.
Reheating: microwave individual portions for 1 to 2 minutes, or cover larger pieces with foil and warm in a 300°F oven for 10 to 15 minutes.

What Goes Well with This Casserole

A bright fruit salad with citrus and mint cuts the richness of the custard. Scrambled eggs or a side of crisp bacon add extra protein if you’re feeding a crowd. Hot coffee with a splash of cream rounds out the meal nicely.

Frequently Asked Questions

Can I use raw chicken?

No, the chicken must be fully cooked before it goes into the casserole. The baking time is for setting the custard, not for cooking raw meat.

Can I skip the overnight soak?

You can bake immediately, but the casserole won’t have the same soft, pudding-like center. Reduce the bake time by about 5 minutes and expect a texture closer to a savory bread pudding.

What’s the best chicken to use?

Rotisserie or leftover roasted chicken works best because it’s already tender. Avoid breaded fried chicken, as the coating gets soggy during the soak.

Can I freeze this unbaked?

Yes, assemble the casserole, cover tightly, and freeze for up to 2 months. Thaw overnight in the fridge, then bake as directed, adding 10 to 15 minutes to the bake time.
