I think every cook has their own style. We get in rhythms or patterns, have our own unique flavor palate. Many of us have childhood favorite foods. I like experimenting in my kitchen, but I tend to fall back on my tried and true recipes. My new recipe for a chicken broccoli pasta bake borrows heavily from one of my childhood favorites – my Mom’s recipe for chicken divan. It’s a complete meal in a casserole dish and a great option for a busy weeknight.

Ingredients for chicken broccoli pasta casserole

  • Rotisserie Chicken – I always use help from my grocery store for casserole recipes. It’s so much quicker than starting with raw chicken. But if you’d like to use chicken breast you’ve cooked yourself, let me suggest my guide for how to make frozen chicken in the Crock-Pot.
  • Frozen Broccoli – I use a 16-oz package of premium frozen broccoli florets for this recipe. I microwave them according to package directions before adding them to the pasta mixture.
  • Pasta – Use a sturdy short pasta. I like rigatoni. But you could use another shape like penne. Or even different types of pasta, like chickpea pasta or whole wheat pasta.
  • Cheddar Cheese – Be sure to great your own cheese for this recipe. It melts and tastes so much better than pre-grated cheese.
  • French Fried Onions – These are optional, but I like the crunchy texture they add to cooked pasta.
  • Sauce Ingredients – This is where I borrowed heavily from my already published chicken divan recipe. Why re-invent the wheel? Here’s what I use for the sauce –
    • melted butter
    • cream of chicken soup
    • mayonnaise
    • sour cream
    • lemon juice
    • parsley
    • salt

Instructions for broccoli chicken pasta bake

Bring a large pot of salted water to a boil. Cook the pasta to al dente according to package directions and drain the pasta water. Meanwhile, microwave the broccoli according to package directions. And then chop as needed so it’s in bite-sized pieces.

In a large bowl or glass measuring cup, melt the butter. Stir in the cream of chicken soup, mayonnaise, sour cream, lemon juice, parsley and salt. Whisk until smooth.

In the empty pasta pot, stir together the cooked pasta with the rotisserie chicken, cooked broccoli, one cup of the shredded cheddar cheese and the sauce. Evenly spread the pasta mixture into a 9×13 baking dish. Top the casserole with the remaining cheddar cheese. And then the french fried onions.

Bake the casserole uncovered at 350 degrees F for about 30 minutes, until nice and bubbly hot.

Serving suggestions

I’m always a fan of doubling up on vegetables. Serve this casserole with a side of green beans and/or a simple salad for a hearty and nutritious meal. Here’s some recipe suggestions –

    • Air Fryer Green Beans
    • Spinach Strawberry Salad
    • Crockpot Applesauce

Storage directions

Cover the casserole dish with aluminum foil. Or scoop into an airtight container. Store leftovers in the refrigerator for 3-4 days or in the freezer for up to one month.

Kitchen tools
