For the Meat Mixture
- 2 lbs ground beef (I use 80/20 for that authentic fast food flavor)
- 1 medium onion, finely diced (about 1 cup)
- 3 cloves garlic, minced (or more, I won’t judge)
- 2 tablespoons Worcestershire sauce
- 1 tablespoon yellow mustard
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
For the Casserole Base
- 6 chicken hamburger buns, torn into bite-sized pieces (stale ones actually work better!)
- 2 tablespoons butter, melted
- 1 teaspoon sesame seeds
For the Special Sauce
- 1 cup mayonnaise (full fat is best here)
- 1/4 cup ketchup
- 2 tablespoons sweet pickle relish (the secret ingredient!)
- 1 tablespoon yellow mustard
- 1 tablespoon white vinegar
- 1 teaspoon sugar
- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
For Toppings
- 2 cups shredded cheddar cheese (the orange kind for that classic look)
- 1 cup shredded lettuce
- 1/2 cup dill pickles, chopped
- 1/4 cup diced onion
- 8 slices American cheese (yes, the plastic-wrapped kind)
Variations
This recipe is super flexible, allowing you to get creative based on what you have on hand or your dietary preferences. Here are some fun variations:
- Swap the protein: Try using ground turkey or chicken instead of beef for a lighter version.
- Make it vegetarian: Substitute the beef with lentils or black beans for a hearty plant-based option.
- Add some heat: Spice things up by adding diced jalapeños or chili flakes to the meat mixture.
- Change the cheese: If you’re not a fan of cheddar or American cheese, feel free to use your favorite melting cheese like mozzarella or pepper jack.
How to Make Big Mac Casserole
Step 1: Prepare the Meat Mixture
Start by browning the ground beef in a large skillet over medium heat. As it cooks, add in the finely diced onion and minced garlic. Sauté everything together until the meat is fully cooked and the onions are soft. This step is crucial because sautéing the onions brings out their natural sweetness and enhances the overall flavor of our casserole.
Step 2: Mix in Seasonings
Once your meat mixture is ready, stir in Worcestershire sauce, yellow mustard, salt, black pepper, garlic powder, and onion powder. These seasonings are what give our casserole that unmistakable Big Mac flavor. Make sure everything is well combined before moving on.
Step 3: Assemble the Casserole
In a large baking dish, layer half of your torn hamburger buns at the bottom. Then spoon half of your meat mixture over them. Drizzle some of that delicious special sauce on top—don’t be shy! Repeat with another layer of buns followed by meat and sauce. Top all this goodness with shredded cheddar cheese and slices of American cheese.
Step 4: Bake to Perfection
Preheat your oven to 350°F (175°C) and bake the casserole for about 30 minutes or until everything is bubbly and golden on top. Your kitchen will smell heavenly during this time!
Step 5: Add Fresh Toppings
Once it’s out of the oven, let it cool slightly before adding shredded lettuce, chopped dill pickles, and diced onions on top. These fresh toppings add that extra crunch we all love!
And there you have it—a delightful Big Mac Casserole that captures all those beloved fast-food flavors in one warm dish! Enjoy every bite with family and friends; I know they will absolutely love it!
Pro Tips for Making Big Mac Casserole
Making the perfect Big Mac Casserole is all about those little details that elevate the dish, so let’s dive into some pro tips to ensure your casserole turns out amazing every time!
-
Use Stale Buns: Stale bread absorbs moisture better and helps create a more cohesive texture in your casserole. It prevents the dish from becoming too soggy while baking!
-
Pre-cook Your Beef: Browning the ground beef with the onions and garlic enhances the flavors significantly. This extra step adds depth and richness to your casserole.
-
Don’t Skip the Special Sauce: The combination of mayonnaise, ketchup, relish, mustard, vinegar, and spices creates that authentic Big Mac taste. Make sure to mix it well for even flavor distribution.
-
Layer Strategically: For maximum cheesiness and flavor, layer half of your meat mixture, followed by half of your cheese, then repeat. This ensures every bite is filled with cheesy goodness!
-
Let It Rest Before Serving: Allowing your casserole to sit for about 10 minutes after baking helps it set up nicely. This makes serving easier and gives it a chance to cool slightly so everyone can dig in without burning their mouths!
