Ingredients

- Turkey – I use leftover cooked turkey breast. If you really want to make this recipe and you don’t have leftover turkey you can cook turkey breast and dice for this recipe.
- Butter – I like to use salted butter, but unsalted butter will work too.
- Mushrooms – You can use white or baby portabella mushrooms for this recipe.
- Flour – All purpose flour is needed to thicken the milk and broth.
- Seasonings – For this recipe I use dried thyme leaves. I also used salt and pepper to season the mushrooms, pasta, and cream sauce.
- Peas & Carrots – I love using the frozen peas and carrots mix.
- Milk – I use whatever I have on hand– 2% or Whole Milk. Either work. I have not tested this recipe on a dairy free / plant based milk. But I’m sure it would work, just flavors might be a bit different.
- Chicken Broth – This helps to flavor the cream sauce. If you don’t have chicken broth you can always use water.
Directions
Preheat the oven to 400°. Grease a 9-by-13-inch baking dish and set to the side.
Cook the pasta according to package directions until just barely al dente; drain.
Add 2 tablespoons butter to the skillet. Add the mushrooms and thyme; season with salt and pepper. Cook until the mushrooms start to soften, about 3 minutes. During the last minute of cooking, add the chopped turkey, mix well, and transfer to a bowl and set to the side.

Melt the remaining 3 tablespoons butter in the skillet. Whisk in the flour and cook for 1 minute. Whisk in the milk and broth and bring to a boil, then simmer for 2 to 3 minutes to thicken. Stir in ½ cup Parmesan.

Then add in the peas and carrots mix, and turkey. Season with salt and pepper if desired.
Add the pasta and cooked mushrooms/turkey to the sauce. Toss well to combine. Transfer the pasta mixture to the prepared baking dish.

Sprinkle with the remaining ½ cup Parmesan. Bake until the top is golden-brown and the sauce is bubbling, 12 to 15 minutes. Carefully, remove from the oven and serve immediately.
