Begin by heating a large skillet over medium-high heat and add the olive oil. Once the oil is hot, add the mushrooms and saute until tender and slightly browned. Remove and set aside
In the same skillet, add the beef and cook until browned. This should take about 5-7 minutes. Add chopped onion and minced garlic and cook for about 2-3 minutes until the onion is translucent.
Add the marinara sauce and cook for about 3 minutes. Add the rest of the spices and stir well to combine. Stir the sour cream, mushrooms and beef broth, stir well to fully incorporate then reduce the heat to low and let it simmer for about 5 minutes.
Taste and adjust seasonings as needed.
Serve the beef stroganoff over a bed of egg noodles or rice. Garnish with chopped parsley.
