Big Mac Casserole: The Comfort Food Remix You Didn’t Know You Needed

There’s something magical about the flavors of a Big Mac—the tangy special sauce, the melty cheese, the crisp lettuce, and that unmistakable beefy goodness. But what if I told you we could take all that nostalgia and bake it into one cozy, shareable casserole? This dish is perfect for busy weeknights, game day gatherings, or anytime you’re craving that fast-food fix without leaving your kitchen.

Ingredients You’ll Need

• 1 lb ground beef – The star of the show! Opt for 80/20 for the juiciest results.
• 1 small onion, diced – Sweet or yellow onions work beautifully here.
• 2 cloves garlic, minced – Because everything’s better with garlic.
• 1 tsp Worcestershire sauce – A little umami boost for the beef.
• 1 cup shredded cheddar cheese – Sharp cheddar adds a nice bite.
• 1 cup shredded American cheese – For that classic Big Mac meltiness.
• 1 (16 oz) bag frozen shredded hash browns – The crispy, golden base of our casserole.
• 1/2 cup dill pickle slices, chopped – Don’t skip these! They add the perfect tang.
• 1/2 cup shredded iceberg lettuce – For that fresh crunch.
• 1/4 cup sesame seeds – A sprinkle for that signature Big Mac bun flavor.

For the Special Sauce:

• 1/2 cup mayonnaise – The creamy foundation.
• 2 tbsp ketchup – Sweet and tomato-y.
• 1 tbsp yellow mustard – Just like the real deal.
• 1 tbsp sweet pickle relish – Tiny bursts of sweetness.
• 1 tsp white vinegar – A touch of acidity to balance the richness.
• 1/2 tsp paprika – A whisper of smokiness.
• 1/2 tsp onion powder – For depth.

Let’s Get Cooking: Step-by-Step

Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish. Trust me, you’ll want that non-stick insurance!

Step 2: Crisp Up the Hash Browns
Spread the frozen hash browns evenly in the baking dish. Pop them in the oven for about 15 minutes while you prep the rest—this gives them a head start on getting golden and crispy.

Step 3: Brown the Beef
In a large skillet over medium heat, cook the ground beef with the diced onion and garlic until the beef is no longer pink and the onions are soft. Drain any excess grease, then stir in the Worcestershire sauce. Your kitchen should smell heavenly right about now.

Step 4: Whip Up the Special Sauce
In a small bowl, whisk together all the sauce ingredients until smooth. Taste and adjust—maybe an extra pinch of paprika if you’re feeling adventurous!

Step 5: Layer the Goodness
Pull the hash browns out of the oven (they should be slightly toasted by now). Spread the beef mixture over the top, then drizzle with half of the special sauce. Sprinkle both cheeses evenly over the beef—this is where the magic happens.

There you have it—a deliciously nostalgic Big Mac Casserole that brings all the iconic flavors of the classic burger into an easy, family-friendly dish. With layers of savory ground beef, melty cheese, crisp lettuce, and that signature special sauce, this casserole is sure to become a weeknight favorite.

FAQs

Can I make this casserole ahead of time?

Absolutely! You can assemble the casserole (minus the lettuce and fresh toppings) a day in advance and refrigerate it. Just bake it when you’re ready to serve, then add the lettuce, pickles, and sauce right before eating for the freshest taste.

What can I substitute for the special sauce?

If you’re short on time, a mix of mayonnaise, ketchup, and relish makes a great shortcut version. Or, try Thousand Island dressing for a similar tangy-sweet flavor.

Can I use ground turkey instead of beef?

Yes! Ground turkey or even plant-based crumbles work well if you’re looking for a lighter or meat-free option. Just adjust the seasoning to taste.

How do I store leftovers?

Store any leftovers (without the lettuce) in an airtight container in the fridge for up to 3 days. Reheat in the microwave or oven, then add fresh toppings before serving.

Can I freeze this casserole?

For best results, freeze the baked casserole (without the lettuce and sauce) for up to 2 months. Thaw overnight in the fridge, reheat, and add fresh toppings when ready to enjoy.
