Chicken and Portobello Mushroom Casserole is easy and tasty for dinner!
Meal time doesn’t have to be complicated. That’s why I love a good casserole recipe. The ingredients are typically items you already have in your kitchen cabinets or pantry. And cooking everything in one dish means a lot less clean-up. Dishes are not my favorite chore, so if I can eliminate a few, that is always a win in my book.
For this recipe, you have two options for the Cream of Mushroom Soup. You can use canned soup or opt for a homemade version if you have the extra time. If you use canned soup, I promise I don’t judge. As much as I love making dishes from scratch, there simply isn’t always enough time to make this happen.
This version uses shredded, cooked chicken and I always prefer the thighs meat. It provides more flavor and doesn’t dry out as easily. But feel free to use either that you have on hand. A rotisserie chicken or leftover pieces of chicken also work.
Ingredients for Chicken and Portobello Mushroom Casserole:
- Extra-wide egg noodles (regular or whole wheat work!)
- Extra virgin olive oil
- Unsalted butter
- Red onion
- Garlic powder
- Sea salt
- Black pepper
- Portobello mushrooms
- Cream cheese
- Cream of mushroom soup (canned or homemade)
- Chicken broth (only needed if using canned soup)
- Sour cream
- Dried thyme
- Shredded, cooked chicken
- Frozen peas
- Parmesan cheese
- Fresh parsley
How to Make Chicken and Portobello Mushroom Casserole:
Cook egg noodles according to package directions. Drain and toss cooked noodles with two or three tablespoons cream of mushroom soup to prevent sticking. Set aside.
While the water for the noodles comes to a boil, place the top oven rack in the center position and pre-heat oven to 400°F. Lightly grease a 4-quart casserole dish and set aside.
Heat one tablespoon each olive oil and unsalted butter in a large skillet set over medium heat. Add red onion and one teaspoon garlic powder. Season with salt and black pepper, to taste, and stir to combine. Sauté, stirring occasionally, for 3-4 minutes, or just until onion begins to soften.
Add mushrooms and remaining butter to the skillet and season lightly with additional salt and black pepper, if desired. Sauté, stirring occasionally, for 5-7 minutes or until the mushrooms are nicely browned.
Remove the skillet from heat and stir in the softened cream cheese until thoroughly combined. Set aside.
In a medium mixing bowl, combine the cream of mushroom soup, chicken broth (if using canned soup), sour cream, remaining garlic powder, and thyme. Pour the mixture into the skillet and stir to combine.
Add the shredded chicken, frozen peas, and cooked noodles to the skillet. Season with salt and black pepper, to taste, and gently toss to combine.
Note: If your skillet is not large enough to combine all ingredients, use a large mixing bowl instead.
Transfer to the prepared casserole dish and top with the freshly grated Parmesan cheese. Cover with a lid or sheet of aluminum foil and place in the pre-heated oven.
Bake the casserole for 20 minutes, then carefully remove the lid or foil. Bake for another 5-10 minutes or just until the top is nicely browned. Remove from oven and garnish with fresh chopped parsley right before serving. Enjoy!
