Easy Step-by-Step Guide

Rest a minute and add the extras:
Let it hang out for five minutes after leaving the oven The sauce will settle and it slices much neater Sprinkle with parsley flakes more Parmesan and some red pepper if you are into it
Bake away:
Slide into your hot oven for about twenty to twenty five minutes Wait for bubbling edges and a deep golden top For extra crunch hit broil for just a minute or two but keep an eye on it
Load into pan:
Spoon that mixture into your buttered dish Smooth the top and layer with mozzarella
Mix everything together:
In a big bowl toss the drained pasta chicken shreds and broccoli Pour over your creamy Alfredo Fold until coated all over
Finish the Alfredo:
Turn your heat low then add Parmesan garlic powder onion powder and salt and pepper Stir till melty and smooth Taste and season more if you want
Thicken the sauce:

Start the Alfredo sauce:
Melt butter in a big saucepan then whisk in the flour for about a minute This will get rid of that raw flour taste and make your sauce super smooth
Steam the green stuff:
Chop broccoli into small bits and steam three to four minutes till vivid green and just tender Drain well so the sauce does not get watery
Boil your pasta:
Fill a large pot with salted water and bring to a boil Drop in your pasta Cook only till barely firm because it will cook more in the oven Drain and set aside

Turn on your oven to 375 Fahrenheit Grease your baking dish (9x13 works great) with butter or spray to keep from sticking

The Parmesan here is key Just a handful gives so much savory flavor My kids always scoop off that cheesy crust before anything else That is when I know supper is a winner

Keeping Leftovers Fresh

Let everything cool before you pack it up Stick it in the fridge for up to four days in an airtight container Freezing? Wrap tight in foil and stash away for up to two months Thaw overnight then reheat covered so it does not dry out

Swap Options

No penne or rotini? Any short thick pasta works Leftover turkey is perfect instead of chicken Cauliflower can sub for broccoli Lighten it up with half and half instead of cream and part skim mozzarella

How to Serve

Scoop out piping hot and grab a simple salad to go with Garlic bread is always a hit for mopping up sauce Honestly this stands on its own as a meal but is even better with a crisp veggie side

Recipe FAQs

→ Can I use other types of pasta?

Definitely! Swap out penne or rotini for elbow macaroni, ziti, or fusilli, and it'll still work great.

→ How can I make this dish lighter?

Go lighter by picking part-skim mozzarella and swapping heavy cream for half-and-half.

→ Can I prepare this ahead of time?

Throw it all together, cover the dish, and stash it in the fridge up to a day in advance. Bake a bit longer if it’s cold from the fridge.

→ What protein alternatives work in place of chicken?

Diced turkey, cooked ham, or even sautéed mushrooms instead of chicken totally work here.

→ How do I reheat leftovers?

Pop leftovers in the oven at 350°F (175°C) until they’re heated through, or zap ’em in the microwave—stir once or twice so everything gets nice and hot.

→ Is it possible to freeze this dish?

You bet! Get it all set up in the pan and freeze before baking. Thaw in the fridge overnight, then just bake as usual.

Ingredients

→ Base

01 200 grams broccoli florets, chopped into small pieces and steamed just until tender
02 340 grams pre-cooked shredded chicken
03 240 grams uncooked penne or rotini pasta, about 3 cups

→ Alfredo Sauce

04 0.25 teaspoon ground black pepper, more or less to taste
05 0.5 teaspoon salt, taste and adjust if you need
06 16 grams regular flour
07 75 grams Parmesan cheese, grated fresh
08 0.5 teaspoon garlic powder
09 480 millilitres full-fat milk
10 28 grams plain unsalted butter
11 0.5 teaspoon onion powder
12 240 millilitres heavy cream

→ Topping

13 100 grams mozzarella, shredded

→ Optional Garnishes

14 Some fresh parsley, chopped
15 Extra Parmesan, grated
16 Sprinkle of red pepper flakes

Steps

Step 01

Pull the dish out of the oven and give it a few minutes to chill before serving. If you like, shower on some parsley, more Parmesan, or a dash of chili flakes.

Step 02

Slide the casserole into the oven and bake until bubbling and the cheesy top gets golden, about 20–25 minutes. Want it extra crispy? Pop it under the broiler for 1–2 minutes but watch closely.

Step 03

Spoon the whole mixture into your prepped dish, spread it out, and toss all that mozzarella cheese over everything.

Step 04

In a big bowl, mix together your drained pasta, the chicken, and the broccoli. Dump in the Alfredo sauce and gently stir so it all gets coated.

Step 05

Whisk in the milk and cream slowly so you don't get lumps. Keep whisking until it thickens up, about 4–5 minutes on a gentle simmer. Turn the heat down low and stir in the Parmesan, garlic powder, onion powder, salt, and black pepper. Mix until smooth and creamy—taste and tweak seasoning if you want.

Step 06

Get your butter melted in a large pan over medium. Sprinkle in the flour, then stir for about a minute to make a smooth base.

Step 07

If you haven't already, chop up your broccoli nice and small. Steam it for 3–4 minutes 'til it's bright green and a little tender. Make sure to drain off any extra water.

Step 08

Boil a big pot of salted water. Toss in the dry pasta and let it cook till it's barely tender, around 8–10 minutes. Drain really well and keep it handy.

Step 09

Turn your oven on to 190°C so it gets hot while you prep. Grab a 33x23 cm dish and wipe on some butter or spray—this keeps sticking from being a problem.

Notes

  1. Grabbing cooked chicken and ready-to-steam broccoli saves you a bunch of time.
  2. You can put it together the night before, stash it in the fridge with a cover, then just bake, adding 5–10 extra minutes since it'll be cold.
  3. Go lighter by swapping in half-and-half for the cream, and use low-fat mozzarella.
