A comforting weeknight dinner of browned ground beef, golden mushrooms, and a silky sour cream sauce, spooned over tender egg noodles. It uses everyday ingredients and comes together in one skillet.
Use full-fat sour cream and keep the pan off the heat when you stir it in. Lower-fat versions and high heat are the most common reasons for a grainy sauce.
If the sauce looks thin, simmer it for 2 to 3 more minutes. If it looks too thick, loosen it with a splash of beef broth or milk.
If the sauce turns slightly grainy, take it off the heat and whisk in a spoonful of warm beef broth until it smooths out.
Store leftovers in an airtight container in the refrigerator for up to 3 days. Keep the noodles separate from the sauce if you can, since they soften as they sit.
Reheat the sauce gently in a skillet over low heat with a splash of beef broth, stirring often, and do not let it boil. This recipe is not recommended for freezing because the sour cream sauce can separate when thawed.
The calorie count is an estimate based on 4 servings that include the noodles.
