For serving: butter noodles or mashed potatoes and fresh parsley
Instructions
Slow cook beef. Place 1 1/2 pounds stew meat and 8 ounces mushrooms in the slow cooker. Sprinkle 1 ounce onion soup mix over top. Then pour 1 1/2 cups beef broth and 2 Tablespoons Worcestershire sauce in. Cook on low for 5 to 6 hours or high for 3 to 4 hours.
Add creamy ingredients. Remove about 1/4 cup of the broth. Stir in 1/4 cup heavy cream and 1/2 cup sour cream. Whisk in 1 Tablespoon cornstarch. Allow to cook an additional 30 minutes. Salt and pepper to taste.
Serve over butter noodles and sprinkle with fresh parsley if desired.
Notes
If you have time and want to do a quick sear on the beef beforehand, you can do that in a skillet with a little olive oil. You can also use flank or sirloin steak. Use Greek yogurt instead of sour cream to make it a little healthier.Storage: Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat on the stovetop or in the microwave with a splash of cream to loosen the sauce.Freeze: Freeze without the noodles for up to 2 months. Thaw overnight in the refrigerator and reheat gently, stirring to bring sauce together again.
