So I came up with this recipe during that crazy month when both my kids had after school activities every single night, and I needed something I could throw together without losing my mind. After the third night of drive thru dinners, my husband gave me that look that said "if I eat one more burger I might die," and this pasta bake was born from pure desperation.

Last time I made this, my neighbor stopped by when it was in the oven and practically invited herself to dinner after one whiff. Now she texts me to ask "making that chicken pasta thing tonight?" whenever she sees me carrying broccoli into the house.

What You Need

  • Elbow Macaroni: Nothing fancy, just the regular stuff from the pantry
  • White Cheddar: Worth spending the extra buck on the good stuff here - that sharp tang makes all the difference
  • Already Cooked Chicken: Rotisserie chicken from the grocery store is my savior, but leftover grilled chicken works too
  • Broccoli: Cut it small enough that your kids can't easily pick it out
  • Fresh Garlic: Those little jars of pre minced stuff will work in a pinch, but fresh really does taste better

I figured out the milk broth combo after making this about six times. First try was just milk, and it was kinda bland. All broth made it too salty. The combo is that sweet spot where the pasta soaks up all the good chicken flavor but still gets creamy.

Step-by-Step Instructions

The Dump and Stir
Throw everything except the chicken, broccoli, and cheese straight into the baking dish. This isn't just lazy cooking though it totally is - it actually works better because the pasta releases its starch right into the sauce. That first stir is super important though - I learned the hard way that if you skip it, you'll end up with pasta stuck to the bottom like cement.
First Bake
When you put the foil on and pop it in the oven, you get about 20 minutes to deal with whatever chaos is happening in your house. I usually use this time to help my third grader with math homework while simultaneously folding laundry and feeding the dog. The pasta needs this covered time to soak up the liquid without drying out.
The Mid Bake Mix In
Don't freak out when you take off the foil and see a bunch of liquid - that's exactly what you want. This is where you dump in the chicken, broccoli, and most of the cheese, give it a good mix, and watch it transform. The still firm pasta and nearly raw broccoli finish cooking perfectly in round two.
Final Stretch
Taking the foil off for the last 20 minutes gives that gorgeous golden cheese top everybody fights over. You could broil it for a minute at the end if you're feeling fancy, but honestly, who has time for that on a Wednesday night? While it finishes, you've got time to throw together a bagged salad or just collapse on the couch for 20 blissful minutes.

First time I made this, I used too small of a dish and it bubbled over, creating a smoky mess in my oven. Learn from my mistakes and use a proper 9x13 pan even if it looks too big at first.

What to Serve With It

Honestly? Usually nothing. This is a complete meal in my house. But if company's coming or I'm feeling particularly virtuous, I'll throw together a simple side salad or warm up some crusty bread. My kids call this "yellow broccoli pasta" and request it at least once a week.

Mix It Up

If you get bored with this version, try swapping the broccoli for cauliflower or throw in some frozen peas during the last 10 minutes. My husband likes when I add mushrooms, but the kids stage a full rebellion when I try it. Sometimes I use pepper jack cheese instead of white cheddar when I'm feeling spicy. You can basically use whatever odds and ends are in your fridge - it's pretty forgiving.

Leftovers Situation

This reheats like a dream for lunch the next day. Just splash a little water or milk in before microwaving to loosen it up. I've been known to eat it cold straight from the fridge when no one's looking. My husband takes it to work and gets "lunch envy" comments from his coworkers.

This recipe has saved my sanity on countless weeknights. It might not be fancy enough for company, but it's become our family's definition of home cooking - simple, satisfying, and just good enough to make me feel like I haven't completely given up on feeding my family properly. Sometimes the best recipes aren't the ones with exotic ingredients or complicated techniques - they're the ones that actually get made, week after week, because they work with real life.

Frequently Asked Questions

→ Can I use a different type of pasta?
Yes! Small pasta shapes like shells, rotini, or penne work well. Cooking time might need slight adjustment for larger shapes. Avoid long pasta like spaghetti as it won't cook evenly in this method.
→ Can I use frozen broccoli instead of fresh?
Absolutely! No need to thaw first - add the frozen broccoli florets directly to the dish. They'll thaw and cook perfectly during the second bake.
→ How do I prevent the pasta from sticking to the bottom?
Make sure to give everything a very thorough stir before the first bake, and again when you add the chicken and broccoli. The pasta should be completely submerged in liquid.
→ Can I prep this ahead of time?
This recipe works best when baked immediately after assembly. However, you can prep all ingredients (cook and dice chicken, chop broccoli, grate cheese) ahead of time to make assembly quick.
→ What can I substitute for white cheddar?
Regular sharp cheddar works perfectly. Monterey Jack, Colby, or a mixture of cheeses will also be delicious. Use whatever melting cheese you have on hand!
→ Can I add other vegetables to this dish?
Definitely! Cauliflower, peas, diced bell peppers, or spinach all work well. Add hearty vegetables with the broccoli, and quick-cooking ones like spinach just before the final bake.

Yield: 6 Servings

Ingredients

→ Base Ingredients

01 8 oz elbow macaroni (about 2 cups uncooked)
02 2½ cups milk (whole milk works best)
03 1½ cups chicken broth
04 3 cloves garlic, minced

→ Seasonings

05 1 teaspoon kosher salt
06 ¾ teaspoon freshly ground black pepper
07 1 teaspoon Italian seasoning
08 A pinch of red pepper flakes (optional, for a touch of heat)

→ Main Components

09 3 cups cooked chicken, diced (about 14-16 oz, rotisserie chicken works great!)
10 3 cups fresh broccoli florets (about 10 oz, cut into bite-sized pieces)

→ Cheese

11 6 oz white cheddar cheese, freshly grated (about 2½ cups)
12 Grated parmesan cheese for topping (as much as you like!)

Instructions

Step 01

Set your oven to 400°F (200°C) and give it some time to heat up while you prepare the casserole.

Step 02

In a 9×13 inch casserole dish, add the uncooked elbow macaroni, milk, chicken broth, minced garlic, kosher salt, black pepper, Italian seasoning, and red pepper flakes (if using). Give everything a really good stir to ensure the macaroni is evenly distributed and not clumping together. This mixing step is crucial to prevent the pasta from sticking to the pan!

Step 03

Cover the casserole dish tightly with aluminum foil. Bake for 20 minutes. The pasta will begin to cook and absorb some of the liquid during this time.

Step 04

Remove the dish from the oven and carefully peel back the foil (watch out for hot steam!). Give the pasta a good stir - don't worry if there seems to be a lot of liquid at this point, it will thicken up nicely. Add the diced cooked chicken, broccoli florets, and about 2 cups of the grated white cheddar (reserve about ½ cup for topping). Stir until everything is well combined and the broccoli is moistened by the liquid. The residual heat will help melt the cheese and create a creamy sauce.

Step 05

Sprinkle the remaining ½ cup of grated cheddar evenly over the top of the casserole. Return the dish to the oven, uncovered this time, and bake for an additional 20 minutes. The top should become golden and bubbly, and the broccoli should be tender but still have a bit of bite to it.

Step 06

Remove from the oven and let the casserole rest for about 5 minutes. Serve in generous portions, topped with a sprinkle of grated parmesan cheese and an extra crack of fresh black pepper if desired. This dish is hearty enough to stand alone but also pairs well with a simple green salad on the side.

Notes

  1. This is a true one-dish wonder - the pasta cooks right in the casserole dish, absorbing the liquid and releasing its starch to create a naturally creamy sauce.
  2. Rotisserie chicken is a perfect time-saver for this recipe, but you can also use leftover chicken from another meal or quickly poach chicken breasts.
  3. Leftovers reheat beautifully! Store in an airtight container in the refrigerator for up to 3 days and reheat in the microwave or oven until steaming hot.
