Tips & Variations

- Add a little smoked paprika or chili powder to the beef for a spicy twist.
- To make it gluten-free, ensure your ketchup and mustard are gluten-free varieties.

Ingredients
Main Ingredients
- 1 lb. lean ground beef (96/4)
- 1 lb. russet potatoes, chopped (skin on, bite-sized pieces)
- 1/2 white onion, chopped
- 1/4 cup water
- 1 tsp. olive oil
- 2 tsp. yellow mustard
- 1/2 tsp. garlic powder
- 1/2 tsp. onion powder
- 1 cup shredded cheddar cheese (112g)
Big Mac Sauce
- 1/4 cup mayonnaise (55g)
- 1/4 cup ketchup (65g)
- 1/4 cup dill pickles, chopped
- 1 tbsp. dill pickle juice
Toppings
- 1 vine tomato, chopped
- Handful white onions, chopped
- Handful shredded iceberg lettuce
- 1/4 cup dill pickle chips
Instructions
- Preheat and Prepare Potatoes: Preheat your oven to 375 degrees Fahrenheit. Wash and chop the russet potatoes into small bite-sized pieces, leaving the skin on. Smaller chunks will cook more quickly and evenly.
- Cook Potatoes: Heat a pan over medium heat, add the olive oil, then add the chopped potatoes and 1/4 cup of water. Season generously with salt and pepper. Cook while stirring often to prevent burning, until potatoes begin to soften, about 5 to 10 minutes depending on chunk size. Transfer softened potatoes into a baking dish.
- Cook Ground Beef and Onions: In the same pan, add the ground beef and chopped white onions. Cook until the beef is mostly cooked through and onions are soft. Season with salt, pepper, garlic powder, onion powder, and yellow mustard. Stir well to combine.
- Combine Beef and Potatoes: Add the cooked beef mixture to the baking dish with the potatoes and mix them together thoroughly.
- Add Cheese and Bake: Sprinkle the shredded cheddar cheese evenly over the beef and potato mixture. Cover the dish with foil and bake in the preheated oven for 15 minutes, or until the cheese has melted completely.
- Prepare Big Mac Sauce: While the casserole is baking, mix together the mayonnaise, ketchup, chopped dill pickles, and dill pickle juice in a bowl. Stir until well combined and refrigerate until ready to use.
- Finish and Serve: Remove the casserole from the oven and take off the foil. Drizzle the entire amount of Big Mac sauce over the top, then evenly distribute shredded iceberg lettuce, chopped white onion, chopped tomatoes, and dill pickle chips on the surface. Serve immediately and enjoy your Big Mac inspired casserole!
Notes
- For extra crispiness, you can sauté the potatoes slightly longer before baking.
- Feel free to adjust seasoning to taste, adding more mustard or garlic powder if desired.
- If you prefer less sauce, adjust the amount of Big Mac sauce accordingly.
- This recipe can be made ahead by preparing the beef and potatoes in advance and assembling before baking.
