Beef and Potato Casserole

This flavorful beef and potato casserole makes a wonderful family meal. The savory filling combines ground beef, mushrooms, carrots, onions, and celery simmered in a rich broth, all topped with creamy, cheesy mashed potatoes.

It’s similar to a cottage pie but with extra depth from mushrooms and Worcestershire sauce. You can even prepare it a day ahead — just reheat the potatoes, assemble, and bake when ready. It’s a cozy, satisfying dinner that’s perfect for busy weeknights or Sunday suppers.

Ingredient Notes

• Ground beef: 85% lean gives great flavor and moisture.
• Mushrooms: Add an earthy depth and extra texture.
• Vegetables: Onion, carrot, and celery create a flavorful base.
• Worcestershire sauce: Adds umami and savory depth.
• Mashed potatoes: Make them ahead and reheat before topping.
• Cheddar cheese: Mix into the potatoes for a cheesy crust.

Steps to Make Beef and Potato Casserole

1. Prepare the oven and dish. Heat the oven to 350°F and lightly grease a 2-quart baking dish.
2. Brown the beef. Heat oil or drippings in a skillet, add the beef, and cook until browned. Remove and set aside.
3. Cook the vegetables. Sauté onions, carrots, celery, and mushrooms until tender. Stir in the flour.
4. Simmer the filling. Return the beef to the pan, add broth, Worcestershire sauce, thyme, and pepper, then simmer until thickened and flavorful.
5. Assemble. Spoon the beef mixture into the baking dish. Stir cheese into the hot mashed potatoes and spread over the top.
6. Bake. Bake for about 25 minutes, until bubbling and lightly golden. Broil briefly for a deeper color if desired.
7. Serve. Let rest for a few minutes, then garnish with parsley and enjoy.

Recipe Variations

• Turkey version. Swap ground beef for ground turkey and use chicken broth.
• Vegetarian. Replace beef with cooked lentils or plant-based crumbles.
• Extra cheesy. Sprinkle more cheddar or fontina over the top before baking.
• Dairy-free. Use olive oil mashed potatoes and skip the cheese.

Serving Suggestions

• Serve with a crisp green salad or sliced cucumbers for balance.
• Pair with roasted vegetables or steamed green beans.
• Add a warm roll or slice of garlic bread to complete the meal.

• Oven Prep: Heat the oven to 350°F and lightly grease a 2-quart baking dish.
• Cook the Beef: Heat 1 tablespoon of oil or drippings in a large skillet or sauté pan over medium-high heat. Add the beef, break it up into small pieces, and cook undisturbed for 4 minutes. Continue cooking and stirring for 4 to 5 minutes or until the beef is no longer pink. Remove the beef to a plate and set aside.
  
• Sauté the Vegetables: In the same pan, heat the remaining oil or drippings over medium heat. Add the onions, carrot, celery, and mushrooms and sauté until the onions are translucent. Stir the flour into the vegetables and cook, stirring, for 2 minutes. Add the beef back to the pan and stir to blend.
  
• Simmer the Filling and Assemble the Casserole: Add the beef broth, Worcestershire sauce, thyme, and pepper. Bring to a simmer, then reduce the heat to low, cover the pan, and simmer for 10 minutes or until the vegetables are tender. Add more broth if the mixture is too thick. Taste and add salt, as needed. Turn the ground beef mixture into the prepared baking dish.

  Stir the cheese into the hot mashed potatoes and spoon them over the top of the casserole. Spread the potatoes to cover the filling.
  
• Bake: Bake the casserole for 25 minutes or until the filling is bubbling and the topping is lightly browned. Broil for a minute or two to brown the topping more.
  
• Serve: Serve with a garnish of parsley if desired. Enjoy!
