Ingredients
Meat
- 1 ½ pounds sliced steak
Vegetables
- 8 ounces baby bella mushrooms, sliced
- 1 small yellow onion, sliced thin
- 3 cloves garlic, pressed or minced
Dairy
- 2 tablespoons salted butter
- ½ cup sour cream
Liquids
- ¼ cup beef broth (for loosening sour cream)
- 2 cups plus ¼ cup low sodium beef broth (divided)
- 1 tablespoon beef base
- 1 tablespoon neutral cooking oil
Other
- 2 tablespoons all purpose flour
- Salt and pepper, to taste
- Cooked egg noodles or mashed potatoes for serving
- Fresh minced parsley for serving (optional)
Instructions
- Prepare Ingredients: Whisk the sour cream with ¼ cup of beef broth in a measuring cup to loosen the sour cream for easier incorporation later. Set aside all prepped ingredients as the cooking process moves quickly.
- Cook the Beef: Heat a large cast iron or stainless steel skillet over medium-high heat until hot and add oil. Add sliced steak in batches without crowding the pan. Let it sear undisturbed for about 30 seconds to develop a brown crust, then flip and sear the other side for another 30 seconds. Remove the steak to a plate; it will not be fully cooked yet.
- Sauté Mushrooms and Onions: Add butter to the same pan, then add sliced mushrooms and onions. Sauté until they turn a deep golden brown, about 5-8 minutes. Add the garlic and cook for an additional 30 seconds, stirring to combine.
- Create Sauce Base: Lower the heat to medium-low, sprinkle in the flour and whisk, cooking for 1-2 minutes to remove the raw flour taste. Gradually add ¼ cup beef broth to deglaze the pan, scraping up browned bits from the bottom. Let the broth reduce slightly. Quickly add the beef base and remaining 2 cups beef broth while whisking to create a smooth sauce.
- Simmer and Finish Sauce: Bring the mixture to a boil and then reduce to a simmer. Whisk in the loosened sour cream mixture until fully combined. Return the beef to the skillet and cook for 1 minute to warm it through and finish cooking.
- Season and Serve: Taste the sauce and adjust seasoning with salt and pepper as needed. Serve immediately over cooked egg noodles or mashed potatoes. Garnish with fresh minced parsley if desired.
Notes
- Do not overcook the beef during the initial searing; it should be just browned and not fully cooked.
- Loosening the sour cream with beef broth prevents curdling when adding it to the hot sauce.
- Use low sodium beef broth to have better control over the salt level of the dish.
- Fresh parsley adds a bright fresh flavor as a garnish but is optional.
- Serving over egg noodles is traditional, but mashed potatoes are a delicious alternative.
