Warm, comforting and totally satisfying, chicken and mushroom casserole gets a healthy twist with whole wheat pasta, lean chicken breast, and creamy plain yogurt.

Compared to the average Midwestern family, we didn’t eat a ton of casseroles for dinner growing up. However, there are two casseroles my mom makes quite frequently that I inevitably crave when temperatures plummet here in Michigan: tuna noodle and chicken mushroom. To make the dish healthier, I’ve made a few alterations to how my mom would make it. The end result is still ooey, gooey, cheesy goodness that tastes nothing like healthy food.
Why You’ll Love this Chicken and Mushroom Casserole

Ingredients

- Pasta: I like to use a whole-wheat, bow-tie pasta for this casserole, but any small pasta would work.
- Butter: Used to saute the veggies with some flavor.
- Onion: I prefer a white onion for mild flavor that caramelizes easily.
- Celery: Mild grassy flavor, but full of vitamin C and other nutrients while adding some crunch to the casserole.
- Garlic: Nutty, pungent, and aromatic.
- Mushrooms: A bit meaty and earthy in flavor, I like to use button or cremini mushrooms best.
- Flour: Thickens the sauce of the casserole.
- Chicken broth: Acts as a flavorful base for the sauce.
- Chicken: Shredded chicken breast is my go to, and leftover rotisserie chicken is great for this casserole.
- Yogurt: Plain yogurt is something I took straight from my mom’s recipe, as it adds a bit of tangy flavor and makes it so creamy.
- Mozzarella cheese: Adds to the creamy, comforting nature of this dish while making it cheesy and delicious.
- Lemon juice: Adds a bright, fresh, citrus flavor that helps bring balance and cut through some of the richness.
- Worcestershire sauce: Full, pungent, umami flavor for the sauce.
- Panko: Tops the casserole to get nice and crispy.
- Olive oil: Helps the panko brown in the oven.
- Salt & pepper: For added taste.

Frequently Asked Questions
Why do you cover casserole when baking?
Not all casseroles need to be covered, or you may only need to cover it for part of the time. But it’s usually to make sure the top doesn’t burn.
How to make a casserole taste better?
Sauteing your veggies and browning/cooking your protein before mixing all together in the casserole dish helps add more flavor, along with using a variety of ingredients, adding spices, and topping with fresh herbs.
What is the the most flavorful mushroom?
There are so many types of mushrooms out there, but if you’re looking for strong mushroom flavor, you’ll usually want to go with the maitake or shiitake mushroom
