Ingredients for Easter brunch casserole recipe
- 1/2 cup butter
- 1 cup milk
- 12 large eggs
- 2 cups shredded cooked chicken breast
- 1 cup shredded turkey sausage
- 1 cup shredded mozzarella cheese
- 2 cups fresh baby spinach
- 1 cup diced red bell pepper
- 1 cup diced yellow onion
- 1/2 cup chopped fresh parsley
- 1 cup diced potatoes
- 1/2 cup chicken broth
Don’t stress about the shredded chicken — rotisserie chicken from the store works perfectly here and saves you major time. I’ve also swapped the bell peppers for zucchini when that’s what I had, and it turned out just as good.
Here’s the thing: this brunch casserole recipe tastes even better the next day when all the flavors meld together overnight. That’s exactly why make ahead breakfast casseroles are genius for entertaining. Skip the parsley if you’re not a fresh herb person, but honestly it adds a nice fresh pop.
Step-by-step instructions
1. Preheat your oven to 350°F and grab a 9×13 baking dish. Melt the butter in a small saucepan over medium heat, then pour it into the bottom of your dish, coating evenly. This buttery base helps everything slide out easier later and adds richness to every bite. Make sure the butter covers the entire bottom or some spots will stick when you serve it.
2. In a large bowl, whisk together the 12 eggs and 1 cup of milk until totally combined. The mixture should look pale and a little frothy — that’s perfect. Add the chicken broth and whisk again for about 30 seconds to blend everything smoothly.
3. Dice your potatoes into small cubes about the size of peas and add them to the egg mixture. Then fold in the shredded chicken, turkey sausage, mozzarella cheese, fresh spinach, red bell pepper, yellow onion, and chopped parsley. Gently combine everything so the ingredients distribute evenly throughout — don’t overwork it, just fold it together gently.
4. Pour the entire mixture into your buttered baking dish and use a spatula to spread it evenly. The liquid should fill the dish almost to the top with ingredients floating throughout. Let this brunch casserole recipe sit at room temperature for about 5 minutes so everything settles, then give it a gentle stir.
5. Cover the dish tightly with plastic wrap and refrigerate overnight, or at least 8 hours. This is where the magic happens — the bread-like base absorbs all the custard and the flavors get seriously cozy together. Pro tip: I always set mine up around 8 PM so it’s ready to bake when I wake up at 7 AM.
6. When you’re ready to bake, remove the dish from the refrigerator and let it sit for 15 minutes while the oven preheats to 350°F. Don’t skip this step because it helps the middle cook evenly without the edges overdoing. Bake for 45 minutes uncovered until the top turns golden and a knife inserted in the center comes out clean.
7. Let it rest for 5 minutes straight out of the oven before cutting and serving. This cooling time helps the Easter brunch casserole recipe set up so each piece holds together nicely. Sprinkle extra parsley on top if you want, cut into 10 squares, and watch your guests get seconds.

Storage tips
– Refrigerate leftovers in an airtight container for up to 3 days – You can freeze the unbaked casserole for up to 3 months before baking – Thaw frozen casserole overnight in the fridge, then bake as directedMake-ahead instructions
– Assemble completely the night before and refrigerate covered tightly – For extra convenience, prepare ingredients in separate bags and assemble morning-of – Don’t add the parsley until just before baking so it stays bright greenVariations
– Swap chicken for ground turkey or diced ham for totally different flavors – Use fresh kale instead of spinach if that’s your preference for greens – Add diced mushrooms or broccoli for extra vegetables and nutritionTroubleshooting
– If the top browns too fast, loosely tent with aluminum foil halfway through – Watery texture means eggs weren’t cooked through — bake another 5-10 minutes – Dry and rubbery means you overcooked it — watch it after minute 40Frequently asked questions
Can I freeze this Easter brunch casserole recipe?
Yes, absolutely freeze it. Assemble the entire casserole, cover it tightly with plastic wrap and foil, then freeze for up to 3 months before baking. Thaw it overnight in the refrigerator, then bake at 350°F for 50-55 minutes (add 5-10 minutes since it’s coming from cold). Don’t bake it frozen or the edges will overcook while the middle stays raw.
What if I don’t have turkey sausage?
You can use bacon bits, diced ham, or regular pork sausage instead. Ground Italian sausage also works beautifully if you brown it first and drain off the fat. The key is having about 1 cup of pre-cooked meat mixed through, so swap whatever breakfast meat you prefer.
How do I reheat leftovers?
Reheat individual portions in the microwave for 60-90 seconds, or reheat the whole dish covered in a 350°F oven for 15-20 minutes. Don’t microwave the entire casserole or the edges get rubbery while the middle stays cold. The stovetop method beats both — just heat it gently in a skillet over medium-low heat.
Can I make this casserole without the potatoes?
Totally, you can skip them or use 1 cup diced bread cubes instead for more substance. The potatoes add heartiness and texture, but the Easter brunch casserole recipe works fine without them if you’re watching carbs. Just make sure you have about 4-5 cups of total ingredients so the custard distributes evenly.
