Ingredients You’ll Need
Let’s gather some simple, wholesome ingredients to create this delicious Big Mac Casserole! These are items you might already have in your pantry or fridge.
For the Casserole
- 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
- 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
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
One of the things I love about this recipe is how flexible it is! Feel free to get creative with these variations:
- Swap the protein: Instead of ground beef, try using ground turkey or chicken for a lighter option.
- Add veggies: Sneak in some finely chopped bell peppers or mushrooms for an extra veggie boost.
- Spice it up: Add some chopped jalapeños or hot sauce to the meat mixture if you like a little kick.
- Make it vegetarian: Substitute the beef with lentils or a meat alternative for a delicious vegetarian version.
How to Make Big Mac Casserole
Step 1: Cook the Beef
Start by browning your ground beef in a large skillet over medium heat. As it cooks, break it apart with a spatula. Cooking the meat thoroughly ensures that it’s packed with flavor and safe to eat. Once it’s nicely browned, drain any excess fat.
Step 2: Sauté the Onion and Garlic
Add the diced onion and minced garlic to the skillet with your beef. Sauté until the onion becomes translucent—this brings out their sweetness and adds depth to your dish. It should take about 3-5 minutes.
Step 3: Mix in Seasonings
Stir in Worcestershire sauce, yellow mustard, salt, black pepper, garlic powder, and onion powder. This blend will give your casserole that signature Big Mac flavor profile. Let everything cook together for another minute or two.
Step 4: Prepare the Bun Layer
In a separate bowl, combine torn hamburger buns with melted butter and sesame seeds. Toss well until all pieces are coated. This will create that delightful base layer that mimics the original sandwich!
Step 5: Assemble Your Casserole
In a large baking dish, start layering! First goes half of the bun mixture on the bottom. Then add your beef mixture on top followed by half of your special sauce. Repeat layers until everything is used up.
Step 6: Add Toppings
Sprinkle shredded cheddar cheese over everything—don’t be shy! Then add shredded lettuce, chopped pickles, diced onions, and finish off with slices of American cheese on top. This will melt beautifully as it bakes.
Step 7: Bake
Preheat your oven to 350°F (175°C). Bake uncovered for about 30-35 minutes until bubbly and golden brown on top. The aroma will be irresistible!
Enjoy this comforting Big Mac Casserole with family and friends—trust me; they’ll be asking for seconds!
Pro Tips for Making Big Mac Casserole
Making a delicious Big Mac Casserole is all about getting those flavors just right, and I’ve got some tips to help you do just that!
-
Use Stale Buns: Stale hamburger buns absorb moisture better, giving your casserole that perfect texture without becoming overly soggy.
-
Season the Meat Well: Don’t hold back on the seasoning! The right blend of Worcestershire sauce, mustard, and spices really mimics that fast-food flavor we all love.
-
Layer Smartly: When assembling your casserole, try to layer the ingredients evenly. This ensures every bite has a bit of everything, from beef to cheese to special sauce.
-
Customize Your Cheese: Feel free to mix different types of cheese! Cheddar adds that classic look, but a sprinkle of pepper jack can give it an unexpected kick.
-
Let It Rest: Allowing the casserole to sit for about 10 minutes after baking makes it easier to serve and allows the flavors to meld even more.
