This creamy meatball stroganoff with juicy meatballs, savory brown mushrooms, and a creamy sour cream sauce is the perfect midweek dinner. It's surprisingly easy to make in 30 minutes, yet delivers big on flavor, making it a weeknight win for busy families.
In a large bowl, combine ground meat, egg, breadcrumbs, garlic, oregano, thyme, paprika, salt, and pepper. Mix well to form a cohesive mixture. Roll the mixture into 1-inch meatballs.
Heat olive oil in a large skillet over medium heat. Add meatballs and cook until browned for 4-5 minutes on both sides. Remove meatballs from the pan using a slotted spoon and set aside.
1 tbsp olive oil
In the same pan (with the remaining pan juices), add butter and melt over medium heat. Add the sliced onion and sliced mushrooms and cook until softened, about 5-7 minutes. Season with black pepper.
1 tbsp butter, 1 yellow onion, 1/2 lb brown mushrooms, black pepper
Sprinkle flour over the vegetables and cook for 1 minute, stirring constantly. Gradually whisk in the lamb stock, scraping up any browned bits from the bottom of the pan. Bring to a simmer and cook for 5 minutes, or until slightly thickened. Reduce the heat to low and stir in Dijon mustard and sour cream. Season with salt to taste.
2 tbsp flour, 1 1/2 cups beef stock, 2 tsp Dijon mustard, 1/2 cup sour cream, salt
Return the cooked meatballs to the pan and simmer for 5-7 minutes, or until heated through. Serve immediately over egg ribbon noodles, rice, or mashed potatoes. Garnish with chopped fresh parsley or thyme, if desired.
Notes
Don't crowd the pan: When browning the meatballs, cook them in batches if you're using a smaller pan to avoid overcrowding it. This ensures even cooking.Low heat: To prevent curdling, reduce heat to low or remove the pan from heat altogether before stirring in the sour cream.Thicken the sauce to your liking: If you prefer a thicker sauce, you can add more flour and cook for an additional minute or two, until the sauce reaches your desired consistency.Storage: Store this stroganoff sauce in an airtight container in the fridge for 3-4 days. Reheat on low heat, adding extra stock if it thickens too much. For longer storage, freeze it for up to 3 months.
