In a large pot of salted boiling water, cook the egg noodles according to the package instructions until al dente. Drain and set aside.
In a large skillet, heat olive oil over medium-high heat. Add the sliced turkey and season with salt and pepper. Cook until the turkey is browned and cooked through, about 5-7 minutes. Remove turkey from the skillet and set aside.
In the same skillet, add chopped onion and sauté for 3-4 minutes until soft. Then add minced garlic and sliced mushrooms; cook until mushrooms are golden brown, approximately 5 minutes.
Sprinkle flour over the mushroom mixture, stir to coat, and cook for about 1 minute. Gradually whisk in the chicken broth while stirring to avoid lumps.
Stir in paprika, thyme, and bring the mixture to a simmer. Let it cook for about 5 minutes until the sauce thickens.
Reduce the heat to low and stir in the sour cream until the mixture is creamy. Add the cooked turkey back into the skillet and mix until well combined. Simmer for an additional 2-3 minutes.
Toss the cooked noodles in with the creamy turkey mixture or serve it on top of the noodles in bowls.
