This creamy Chicken Alfredo Bake is my go to comfort dish for celebrations or weeknights when the family is craving something cheesy and hearty It combines pasta bite sized chicken broccoli and a rich Alfredo sauce all bubbling together under a golden cheesy topping If you need to use up leftover chicken or want something that kids and adults love this one always delivers

I first pulled this out of thin air to stretch a bit of rotisserie chicken and now my youngest requests it for every birthday dinner

Ingredients

  • Broccoli florets: For color crunch and a little veggie balance Look for tight green buds and crisp stems
  • Chicken breast or use any cooked chicken: Adds heartiness and protein Opt for organic or fresh rotisserie meat if possible
  • Salt and pepper: Essential for flavor enhancement Always taste and add gradually
  • Olive oil: For sautéing and moisture I go for extra virgin if I want a fuller taste
  • Medium pasta shells or any pasta shape: They catch the sauce beautifully Select bronze cut pasta for better sauce cling
  • Mozzarella cheese: Gives that classic gooey melt Shred your own for best texture and flavor
  • Salted butter: Lays the foundation for the sauce Use real butter for richness
  • Garlic: Adds aromatic depth Choose firm cloves and mince finely
  • All purpose flour: Thickens the sauce Unbleached flour keeps it clean
  • Half and half: Makes the sauce silky and lush Go for fresh dairy for best results
  • Parmesan cheese: Savory backbone to the sauce Grate fresh parm for sharpness and meltability
  • Romano cheese: Boosts the tang and saltiness Use fresh for proper melting
  • Ritz crackers or breadcrumbs: Optional for a buttery crisp top Look for ones without added flavoring

Step-by-Step Instructions

Prepare Chicken:
Pat your chicken breast dry before you butterfly and slice it into thinner pieces Season each piece generously with salt and pepper Heat olive oil in a large skillet on medium high Once shimmering add the chicken and let each side sear until deeply golden About four to five minutes per side is usually right Lower the heat if it splatters too quickly Remove and allow to rest so the juices stay in Slice into bite sized cubes once cool enough to handle
Boil Pasta and Broccoli:
Bring a large pot of water to a boil Add half a tablespoon of salt then drop in your pasta Cook until just al dente Refer to your pasta box but about eight minutes works for medium shells During the last four minutes toss in broccoli florets to soften along with the pasta Drain well to remove excess water
Make Alfredo Sauce:
In a large skillet melt the butter over medium heat Add minced garlic and sizzle for about a minute to bring out its fragrance Sprinkle the flour over the butter and whisk for a full minute to get rid of any raw flour flavor Gradually pour in half and half while whisking staying patient to prevent lumps Let it come to a gentle simmer Drop the heat to low whisk and watch as it starts to thicken Now add Parmesan and Romano in small amounts whisking constantly for a silkysmooth sauce Remove from the heat once melted
Assemble the Casserole:
Add the drained pasta and broccoli to the skillet of Alfredo sauce tossing to coat everything evenly Fold in the diced chicken to distribute through the mixture Spread this into a lightly greased baking dish about nine by thirteen inches Cover the top evenly with mozzarella cheese for that irresistible melt
Bake and Finish:
Slide your casserole into the oven uncovered and bake for ten minutes by which point the cheese should look bubbly and melted For extra crunch scatter Ritz cracker crumbs across the top and bake another five minutes Let it sit out for about five to ten minutes before digging in This makes cutting and serving easier and keeps everyone from burning their tongues

You Must Know

  • Packed with extra protein from chicken and cheese
  • Leftovers stay creamy and are amazing the next day
  • Broccoli keeps its bite and brings important vitamins

My favorite part is always the golden cheesy crust from those Ritz crackers I remember the time my little one helped add the topping for the first time and declared herself the official “crunch captain” for future dinners It is these little moments that make this dish close to my heart

How to Store This Bake

Keep leftovers in a sealed container in the refrigerator for up to three days For longer storage wrap tightly and freeze individual servings It reheats best in the oven at a low temperature to keep the sauce creamy not dry

Simple Ingredient Swaps

No fresh broccoli Use thawed frozen florets just pat them dry No Romano cheese in your fridge All Parmesan works in a pinch Try Swiss or provolone for melting if you run out of mozzarella Gluten free pasta also holds up well here if needed

Frequently Asked Questions

→ Topping (optional)

14 1/2 cup (60 g) Ritz crackers, crushed

Instructions

Step 01

Preheat your oven to 175°C.

Step 02

Butterfly the chicken breast and slice to create two thin fillets. Pat each side dry and season with salt and pepper.

Step 03

Heat olive oil in a large skillet over medium-high heat. Sear chicken until golden, about 4–5 minutes per side. Lower the heat if oil overheats. Transfer chicken to a plate and let rest 5–10 minutes before dicing into bite-size pieces.

Step 04

Bring 4–6 litres of water to a boil and add ½ tablespoon of salt. Cook pasta to al dente, about 8 minutes, adding broccoli florets for the final 4 minutes. Drain thoroughly.

Step 05

In a large skillet, melt butter over medium heat. Add minced garlic and sauté for 1 minute. Whisk in flour and cook for 1 minute. Gradually add half and half, bringing to a gentle simmer. Reduce heat and stir for 1–2 minutes. Slowly incorporate Parmesan and Romano cheese, whisking until smooth. Remove from heat.

Step 06

Mix cooked pasta and broccoli into the sauce, then fold in diced chicken. Transfer mixture to a greased 23 x 33 cm casserole dish and top with shredded mozzarella.

Step 07

Bake uncovered for 10 minutes or until cheese is fully melted. If desired, sprinkle crushed Ritz crackers over the top and bake an additional 5 minutes.

Step 08

Let casserole stand for 5–10 minutes before serving, allowing sauce to absorb and temperature to settle.

Notes

  1. For convenience, substitute frozen broccoli—thawed and well drained in place of fresh.
  2. If Romano cheese is unavailable, use all Parmesan for the sauce.
  3. To prevent dryness, ensure the mixture is sufficiently saucy before baking, particularly if preparing in advance or for leftovers.
