Preparing One-Pot Mushroom Stroganoff is as simple as following these steps:

1. Prepare Ingredients: Gather all ingredients and measure them out to ensure a smooth cooking process.
2. Cook Noodles: In a large pot, cook the egg noodles according to package directions until al dente. Drain, rinse, and set aside.
3. Sauté Aromatics: In the same pot, heat olive oil over medium heat. Add diced onion and sauté for about 3-4 minutes until softened. Incorporate minced garlic and cook for another minute until fragrant.
4. Add Mushrooms: Stir in the sliced mushrooms and cook for 5-7 minutes, allowing them to release their moisture and become tender.
5. Mix Broth and Seasonings: Add the vegetable broth, soy sauce, Dijon mustard, and paprika. Stir well to combine and season with salt and black pepper to taste.
6. Simmer: Bring the mixture to a gentle simmer and let it cook for about 5 minutes until slightly thickened.
7. Combine Noodles: Return the cooked noodles to the pot, mixing them in with the mushroom sauce until thoroughly coated.
8. Incorporate Sour Cream: Remove the pot from heat and slowly stir in the sour cream (or yogurt) until well incorporated and creamy.
9. Garnish and Serve: Plate the dish, garnishing with freshly chopped parsley for a pop of color. Enjoy your meal!
