Ingredients

• 4 cups cooked chicken, shredded or cubed
• 16 oz white or cremini mushrooms, sliced
• 1 lb pasta (rotini, penne, or egg noodles), cooked al dente
• 2 cans (10.5 oz each) condensed cream of mushroom soup
• 1 cup sour cream
• 1/2 cup whole milk
• 1 medium onion, finely diced
• 3 cloves garlic, minced
• 2 cups sharp cheddar cheese, shredded
• 1 cup mozzarella cheese, shredded
• 1/2 tsp dried thyme
• 1/2 tsp paprika
• Salt and black pepper to taste
• 2 tbsp olive oil
• Optional: Fresh parsley for garnish

Directions

Step 1: Preparation and Sautéing

Preheat your oven to 375°F (190°C) and grease a large 9×13 inch baking dish. Heat the olive oil in a large skillet over medium-high heat. Add the diced onions and sliced mushrooms. Sauté for about 7-8 minutes until the mushrooms are golden brown and the moisture has evaporated. Stir in the minced garlic and cook for another minute until fragrant. Season with salt, pepper, thyme, and paprika.

Step 2: Mixing the Sauce and Base

In a large mixing bowl, whisk together the condensed cream of mushroom soup, sour cream, and milk until smooth. Add the cooked pasta, shredded chicken, and the sautéed mushroom mixture into the bowl. Stir in one cup of the shredded cheddar cheese. Mix everything until the chicken and pasta are thoroughly coated in the creamy sauce.

Step 3: Assembling and Baking

Transfer the mixture into your prepared baking dish, spreading it out into an even layer. Sprinkle the remaining cheddar and mozzarella cheese over the top. Cover the dish with aluminum foil and bake for 20 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and starting to brown on the edges.

Step 4: Final Touch and Serving

Remove the casserole from the oven and let it rest for 5 to 10 minutes. This allows the sauce to set so it stays creamy rather than runny when served. Garnish with fresh chopped parsley if desired. Serve warm and enjoy the smiles around the dinner table!

Expert Tips for Perfect Chicken Mushroom Casserole Easy Cheesy Family Make Ahead Feed Crowd

For the best texture, always cook your pasta slightly under “al dente.” The pasta will continue to cook in the oven as it absorbs the sauce, so starting with firm noodles prevents them from becoming mushy. Also, try to shred your own cheese from a block; pre-shredded cheeses are coated in potato starch which can prevent them from melting into that perfectly gooey consistency. If you want a bit of crunch, top the casserole with crushed buttery crackers or panko breadcrumbs mixed with a little melted butter before baking.

Delicious Variations

You can easily customize this dish to suit your preferences. If you want to add more greens, stir in two cups of fresh baby spinach or steamed broccoli florets before baking. For a low-carb version, swap the pasta for cauliflower florets or cooked spaghetti squash. If you prefer a bit of heat, add a diced jalapeño to the onion sauté or a dash of red pepper flakes to the sauce. You can also substitute the chicken for leftover turkey after the holidays!

Frequently Asked Questions

Can I freeze this casserole?

Yes, you can freeze this casserole either before or after baking. If freezing before, assemble the ingredients in a freezer-safe dish, cover tightly with plastic wrap and foil, and freeze for up to 3 months. Thaw in the refrigerator overnight before baking.

What is the best type of mushroom to use?

Cremini mushrooms (also known as baby bellas) are excellent because they have a deeper, more savory flavor than white button mushrooms. However, white button mushrooms work perfectly well and are often more budget-friendly.

How do I store leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 3 to 4 days. Reheat individual portions in the microwave or the oven until warmed through.

Can I make this without condensed soup?

Absolutely. You can make a homemade roux by melting butter, whisking in flour, and gradually adding chicken broth and heavy cream until thickened. Season it well to mimic the flavor of the canned soup.

What should I serve with this casserole?

Since this is a heavy, creamy dish, it pairs beautifully with a light, crisp green salad with a vinaigrette dressing. Steamed green beans or roasted asparagus also make fantastic side dishes.

This Chicken Mushroom Casserole is a quintessential comfort food that checks every box: it’s easy, cheesy, and incredibly efficient for feeding a crowd.
