Ingredients You’ll Need

2 teaspoons Italian seasoning

¾ teaspoon salt

½ teaspoon black pepper

8-12 oz sliced mushrooms

1 medium onion, diced

3 garlic cloves, minced

10.5 oz can cream of mushroom soup

½ cup half and half

½ cup chicken broth

8 oz block cream cheese, cut into cubes

1 cup frozen peas, thawed

1 cup shredded parmesan cheese (or mozzarella)

8 oz spaghetti noodles

Step by Step Instructions

STEP ONE – Place turkey tenderloins into the bottom of the crockpot. Season the top with Italian seasoning, salt, and black pepper.

STEP TWO – Add the mushrooms, onions, and garlic.

STEP THREE – Pour in the cream of mushroom soup, half and half, and chicken broth. Top with cream cheese cubes.

STEP FOUR – Cover and cook on low for 5-7 hours, until the turkey is cooked through and tender.

STEP FIVE – Remove the tenderloins and shred into chunks with two forks.

STEP SIX – Return shredded turkey back to the sauce along with the thawed peas and parmesan cheese. Stir to combine. Cover and cook for an additional 10-15 minutes to let the cheese melt and warm the peas.
