Ingredients You’ll Need

These straightforward yet flavorful ingredients combine to deliver an extraordinary taste reminiscent of your favorite burger, without all the fuss. Each component plays a vital role in recreating that classic Big Mac experience in casserole form.

Lean ground beef (96/4): The foundation of the dish, providing juicy, savory protein without excess grease.
Russet potatoes: Cubed and cooked until tender to add heartiness and texture.
White onion: Adds a sweet, aromatic touch that complements the beef perfectly.
Olive oil: For sautéing potatoes and beef, infusing richness.
Yellow mustard: Brings a subtle tang and depth to the beef mixture.
Garlic and onion powder: Essential seasonings that enhance savory notes.
Shredded cheddar cheese: Melts beautifully to create gooey, cheesy goodness on top.
Mayonnaise, ketchup, dill pickles, and pickle juice: Combined to make that iconic Big Mac sauce that elevates this casserole to crave-worthy status.
Vine tomato: Freshness and juiciness to brighten each forkful.
Shredded iceberg lettuce: Crunchy, cooling contrast to the warm casserole layers.
Dill pickle chips: Bold, tangy crunch to finish the dish with a signature Big Mac twist.

Ingredient Substitutions & Tips

Lean ground beef: Try ground turkey or chicken for a lighter variation.
Russet potatoes: Yukon Gold potatoes work wonderfully for creamier texture.
Shredded cheddar cheese: Swap with mozzarella or Monterey Jack for a different cheesy flavor.
Mayonnaise: Use Greek yogurt or sour cream for a tangier, healthier sauce base.

👨‍🍳 Pro Tips for Perfect Results

Use smaller potato chunks: The smaller the potato pieces, the faster and more evenly they cook, blending beautifully with the beef.
Don’t skip the pickle juice: It’s the secret ingredient that makes the sauce sing with that unmistakable Big Mac zing.
Cover the casserole when baking: This keeps the cheese perfectly melty without drying out the dish.
Use a non-stick or well-oiled pan: This ensures your beef and potatoes don’t stick and burn during cooking.
Rest before serving: Let the casserole sit for a few minutes post-baking to set and make serving easier.

How to Make Big Mac Casserole Recipe

Step 1: Prep and Cook the Potatoes

Start by preheating your oven to 375 degrees Fahrenheit. Wash your russet potatoes thoroughly and chop them into small, bite-sized pieces with the skin left on for added texture and nutrients. Heat olive oil in a pan over medium heat, then add the potatoes along with 1/4 cup of water. Season generously with salt and pepper. Stir often to prevent burning and cook until the potatoes start to soften, about 5 to 10 minutes depending on chunk size. Once tender, transfer the potatoes to your baking dish.

💡 Pro Tip: Smaller chunks mean faster cooking and a creamier texture in your finished casserole.

Step 2: Brown the Beef and Onions

In the same pan, add the lean ground beef and chopped white onions. Cook over medium heat until the beef is nearly cooked through and the onions are soft. Season with salt, pepper, garlic powder, onion powder, and yellow mustard. Stir thoroughly to blend the flavors. Once ready, add this savory beef mixture to the potatoes in the baking dish and gently mix to combine everything.

💡 Pro Tip: Adding mustard at this stage layers in a subtle tang that echoes the classic Big Mac profile.

Step 3: Add Cheese and Bake

Sprinkle a generous cup of shredded cheddar cheese evenly over the beef and potato mixture. Cover the baking dish with foil to lock in moisture and bake in your preheated oven for 15 minutes, or until the cheese melts into irresistible gooeyness.

💡 Pro Tip: Covering with foil ensures velvety cheese without drying out your casserole.

Step 4: Make the Big Mac Sauce

While the casserole bakes, whisk together mayonnaise, ketchup, chopped dill pickles, and a splash of dill pickle juice in a small bowl. Chill this sauce in the fridge until it’s time to drizzle it all over your casserole for that unmistakable Big Mac finish.

💡 Pro Tip: Let the sauce chill to deepen its flavor and thicken for easier drizzling.

Step 5: Assemble and Serve

Once your casserole is out of the oven, remove the foil and drizzle the Big Mac sauce generously across the top. Layer on shredded iceberg lettuce, chopped white onions, juicy chopped tomatoes, and full dill pickle chips. Serve immediately and watch it disappear.

💡 Pro Tip: Go heavy on fresh toppings for a bright, crunchy contrast to the warm casserole.

Common Mistakes to Avoid

Learn from these common pitfalls:

Undercooking potatoes: Raw or crunchy potatoes can ruin the texture balance; be sure they are tender before baking.
Overcooking beef: Dry meat kills the juiciness; cook the beef just until browned and tender.
Skipping seasoning: Proper seasoning in every step builds deep flavor; don’t be shy with salt, pepper, and spices.
Not covering during baking: This dries out cheese and casserole; always bake covered for melty perfection.
Using watery ingredients: Excess moisture in vegetables or sauce can make the casserole soggy; drain well where needed.
Rushing the resting time: Cutting into the casserole too soon can make it fall apart; allow it to set for best slicing.

Delicious Variations to Try
