⭐ How to Make Creamy Smothered Meatballs Casserole
1. Prepare the Meatballs
Preheat oven to 375°F (190°C).
In a large bowl, mix ground beef, egg, breadcrumbs, onion powder, garlic powder, paprika, salt, and pepper until just combined.
Form into evenly sized meatballs or oval patties.
2. Brown the Meatballs
Heat a skillet over medium-high heat.
Sear meatballs for 2–3 minutes per side until browned (they don’t need to be cooked through).
Transfer to a greased baking dish.
3. Make the Creamy Gravy
In the same skillet, melt butter.
Add onion and mushrooms; sauté 4–5 minutes until soft.
Add garlic and cook 30 seconds.
Pour in beef broth, Worcestershire sauce, mustard, salt, and pepper.
Simmer 3–4 minutes, then stir in heavy cream and simmer until slightly thickened.
4. Assemble
Pour the gravy evenly over the meatballs in the baking dish.
5. Bake
Bake uncovered for 30–35 minutes, until meatballs are fully cooked and gravy is bubbling and creamy.
6. Serve
Garnish with fresh parsley and serve hot.
