Turkey and Mushroom Casserole

This casserole recipe is a healthier rendition of a childhood favorite that my mom would prepare with tuna and chicken on a regular basis. As with most of my recipes, once you learn the basic technique, you can easily swap in whatever protein or veggies you have on hand.

Whether that’s leftover Thanksgiving day turkey, shredded rotisserie chicken or leftover pork tenderloin from dinner, this creamy casserole recipe is guaranteed to be a hit with your whole family.

Adding Meat Mixture to Pasta

The first change I made from my mom’s recipe growing up is removing the store-bought, processed cream of mushroom soup. Instead, I make my own mushroom sauce made with real ingredients like butter, flour, onion, mushrooms and chicken broth. It only takes about 10 minutes and is 100x more flavorful than anything you can buy in a can. The best part? You can do this while the pasta cooks to save time.

Garnishing Casserole with Cheese

My other secret ingredient for maximum creaminess and a bit of tanginess is to fold in plain, whole milk yogurt. Not only does it add acidity to balance out the dish but unsweetened yogurt is a great source of protein, calcium and other nutrients. Since turkey is naturally dry, this is a great way to avoid ending up with a dried-out casserole.

PREP: 15 minutes
COOK: 50 minutes
TOTAL: 1 hour 5 minutes
Servings: 8


  • 3 cups cooked turkey (or chicken) (diced, such as rotisserie)
  • 1 pound short cut pasta such as shells or penne (cooked according to package instructions)
  • 1 tablespoon butter
  • 1 cup diced onion
  • 2 teaspoons salt (divided)
  • 1 cup sliced mushrooms
  • 2 tablespoons flour
  • 2 cups chicken broth (low sodium)
  • 16 ounces whole milk plain yogurt
  • 2 cups shredded mozzarella cheese (divided)
  • 2 tablespoons lemon juice
  • 1 tablespoon Worcestershire sauce
  • ½ teaspoon pepper


  • Pre-heat oven to 350 degrees and spray a 9 x 13 baking pan with cooking spray.
  • Cook pasta according to package directions and set aside.
  • Heat butter in a large skillet over medium heat until melted. Stir in onion and 1 teaspoon of the salt. Cook until softened, 3-4 minutes before adding mushrooms. Continue cooking until mushrooms are soft, 3-4 additional minutes.
  • Sprinkle flour into the pan and stir for 30-60 seconds or until flour is absorbed into the pan. Pour in chicken broth and bring to a boil. Reduce heat to low and simmer until sauce thickens, 7-9 minutes.
  • In a large bowl, toss together cooked pasta with diced turkey, plain yogurt, remaining 1 teaspoon salt, half of the cheese (1 cup), lemon juice, Worcestershire sauce and pepper. Add in reduced mushroom sauce to the bowl and stir again.
  • Pour pasta mixture into the prepared baking dish and spread in an even layer. Sprinkle remaining cheese on top and bake until golden brown and bubbly, about 45-50 minutes. Let rest 5-10 minutes before serving to let the casserole settle.

  1. Made this for the second year. Used up the leftover cheese from the charcuterie board and added kale. Love the tanginess from the yogurt. Very tasty!

  2. I tried this recipe, with the best of intentions, and I hate to have to leave this review, but as the recipe is written, this was not good. Not one bit. I made 1/2 of the recipe (as there was only two of us) and we wound up tossing it all out in the trash. I’m bummed out because I thought we would really enjoy this. It is missing some major components. I wouldn’t use plain yogurt in it. I’d use some creme fraiche or even a full fat sour cream. I’d also add in some fresh herbs: parsley, lemon zest, thyme, garlic…something other than just salt and pepper. I’d also just make a recipe for some homemade cream of mushroom soup and add that in.

    1. Hi Laurrie, Thank you so much for your honest review. I’m sorry you didn’t enjoy this casserole. We enjoy it and make it frequently and we love it. The tanginess of the plain yogurt is a great balance to the hearty noodles and shredded cheese. The fresh mushrooms and Worcestershire sauce add a lot of umami flavor as well. Did you add enough salt? Did you use shredded rotisserie or flavorful cooked turkey? So sorry you didn’t enjoy!
