Ingredients

Main Ingredients

• 1 lb. lean ground beef (96/4) — or substitute ground turkey for a leaner option
• 1 lb. russet potatoes, chopped — can swap for sweet potatoes or cauliflower for a lower-carb version
• ½ white onion, chopped
• 1 tbsp olive oil
• ¼ cup water
• 1 tsp yellow mustard
• ½ tsp garlic powder
• ½ tsp onion powder
• 1 cup shredded cheddar cheese (full-fat melts best)

Homemade Big Mac Sauce

• ¼ cup mayonnaise (use olive oil mayonnaise for a lighter option)
• ¼ cup ketchup (regular or sugar-free)
• ¼ cup chopped dill pickles
• 1 tbsp pickle juice

Toppings

• 1 vine tomato, chopped
• Handful of shredded iceberg lettuce
• ¼ cup dill pickle chips, chopped
• Handful of chopped white onion

Instructions

Step 1 — Preheat & Prep the Potatoes

Preheat the oven to 375°F (190°C). Wash and chop the russet potatoes into bite-sized pieces; the smaller they are, the faster they cook.

Step 2 — Cook the Potatoes

Heat the olive oil in a skillet over medium heat. Add the potatoes and ¼ cup water, season with salt and pepper, and cook 5–10 minutes until tender, stirring occasionally. Transfer the potatoes to a greased 8×8-inch baking dish.

Step 3 — Cook the Beef Mixture

In the same skillet, cook the ground beef and chopped white onion over medium heat until browned, about 5–7 minutes. Season with salt, pepper, garlic powder, onion powder and mustard. Drain any excess grease, then spread the beef mixture over the potatoes in the baking dish.

Step 4 — Assemble & Bake

Sprinkle the shredded cheddar cheese evenly over the beef. Cover the dish with foil and bake at 350°F (175°C) for about 15 minutes, until the cheese is fully melted and bubbly.

Step 5 — Make the Big Mac Sauce

While the casserole bakes, combine the mayonnaise, ketchup, chopped pickles and pickle juice in a small bowl. Refrigerate until ready to serve.

Step 6 — Add Toppings & Serve

Remove the casserole from the oven and uncover. Drizzle the Big Mac sauce over the top, then add chopped tomatoes, shredded lettuce, extra pickle chips and chopped white onion. Serve warm.

Helpful Tips

• Use full-fat cheddar for the best melt and creamy texture.
• Don’t overcook the potatoes—aim for tender but not mushy pieces.
• Drain excess grease from the cooked beef to prevent a greasy casserole.
• For a low-carb version, replace the potatoes with cauliflower florets or cauliflower rice.
• Make the casserole a day ahead—flavors often improve after resting in the fridge.

Storage & Reheating

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Freezer: Freeze portions for up to 3 months.
• Reheating: Reheat in a 350°F oven for 10–15 minutes or microwave for about 2 minutes until hot.

Serving Suggestions

Pair the casserole with crispy fries for a classic fast-food feel, a crisp coleslaw or side salad for balance, or roasted vegetables for a healthier plate. For an authentic treat, serve with a chilled glass of soda or a milkshake.
