Ingredients
- 8 ounces whole-wheat pasta
- 1 large head of broccoli, about 1 pound of florets
- 2 tablespoons olive oil
- 1 small white onion
- 8 ounces cremini mushrooms
- 4 cloves garlic, minced
- 2 tablespoons cornstarch
- 1-1/2 cups milk of choice
- 1 cup chicken or vegetable stock
- 1 tablespoon Dijon mustard
- 1 teaspoon kosher salt
- 1/4 teaspoon freshly-cracked black pepper
- 2 cups diced cooked chicken breast, dice or shredded, I used rotisserie chicken
- 1 1/2 cups shredded cheddar cheese, divided
Instructions
- Heat the oven to 400°F and cook 8 ounces whole-wheat pasta according to the package directions. Stir occasionally, until pasta is al dente, about 10-12 minutes.
- Cut the 1 large head of broccoli into bite-size pieces. Quarter the 8 ounces cremini mushrooms and dice the 1 small white onion. Add broccoli florets to the pasta, about a minute or two before the pasta is done.
- When finished cooking, drain well in a colander and run under cold water to stop the cooking process.
- Next, heat 2 tablespoons olive oil in a pan over medium-high heat. Add onion and sauté for 3 minutes, stirring occasionally. Add mushrooms and 4 cloves garlic, cook until mushrooms are slightly golden brown.
- Meanwhile, whisk 2 tablespoons cornstarch and 1/4 cup of the 1-1/2 cups milk of choice in a bowl and set aside.
- Reduce the heat to a low and pour the 1 cup chicken or vegetable stock and the remaining 1 1/4 cup of milk into the pan. Add 1 tablespoon Dijon mustard, 1 teaspoon kosher salt, and 1/4 teaspoon freshly-cracked black pepper, mix well to combine. Cook until the mixture starts to simmer.
- Pour in the prepared cornstarch and milk mixture, mixing thoroughly until the sauce is thickened.
- Take off the heat and stir in 1 cup of the 1 1/2 cups shredded cheddar cheese. Taste and adjust the salt and pepper according to your taste.
- In a baking dish, add the cooked pasta, broccoli, and 2 cups diced cooked chicken breast. Pour over the mushroom sauce, and stir to nicely coat all the ingredients.
- Smooth the top with the back of a spoon and sprinkle with the remaining 1/2 cup of shredded cheese.
- Bake in preheated oven for 15 minutes, until the cheese on top is bubbly and golden. Serve warm and enjoy!
Notes
- Use a preheated oven.
- To make life even easier, use rotisserie or leftover chicken.
- Buy broccoli and cut it into florets. It’s fresher this way, and you have control over how big you want your florets.
- Stir your pasta as soon as you drop it in the water; this prevents the pasta from sticking.
- Cook your pasta a minute short of al dente; this will make sure your pasta isn’t too mushy after baking.
- You can use any fat content milk you’d like to make this dish rich and creamy, or lighter.
- Ideally, shred your cheddar; pre-shredded cheddar never melts that well.
- Add a sprinkle of red pepper flakes, for a touch of heat, if you like.
- Add a dash of nutmeg for a touch of warming winter flavor.

I used a can of cream of mushroom soup in place of the milk and corn starch, added a tiny bit of 2% milk to the sauce.
Sounds great
What is the best milk to use for this recipe in order to keep the calories the same?
I love using 2% milk. But you can use any milk of your choice. The issue is the taste and consistency will change a bit. Depends on your calorie needs
It definitely took a while to make and, I personally didn’t add the mushrooms, garlic or mustard because I just don’t like those but in the end, it was a delicious meal!
This was delicious but labor intensive.
Would make again but would add 1/2 to 1 tsp. of thyme.
That sounds like a great addition.
What size baking dish is used with the broccoli chicken pasta casserole recipe?
Hi. I used 9 x 13
Can you use almond milk?
