How to Make Big Mac Casserole
Step 1: Cook the Beef
Start by browning your ground beef in a large skillet over medium heat. Use a spatula to break it apart as it cooks. This step is crucial as you want to develop that rich flavor from browning. Once it’s fully cooked and no longer pink, drain any excess fat.
Step 2: Sauté Onions and Garlic
Add the finely diced onions and minced garlic to the skillet with your cooked beef. Sauté them until they’re soft and fragrant—about 5 minutes. This step really brings out their sweetness and adds depth to our casserole.
Step 3: Mix in Seasonings
Stir in Worcestershire sauce, yellow mustard, salt, black pepper, garlic powder, and onion powder. Let everything simmer together for about 2-3 minutes so the flavors meld beautifully.
Step 4: Assemble the Casserole
In a large bowl, combine your torn hamburger buns with melted butter and sesame seeds. Next, layer half of this bun mixture in a greased baking dish. Then add half of your beef mixture over the buns followed by half of your special sauce. Repeat these layers until everything is used up.
Step 5: Top It Off
Finish by sprinkling shredded cheddar cheese evenly over the top. Add slices of American cheese on top as well—this will melt perfectly during baking.
Step 6: Bake
Bake your casserole in a preheated oven at 350°F (175°C) for about 25-30 minutes or until bubbly and golden on top. The aroma will drive everyone wild!
Step 7: Serve with Toppings
Once out of the oven, let it cool slightly before serving. Top each portion with shredded lettuce, chopped dill pickles, and diced onions for that authentic Big Mac finish.
And there you have it—your very own Big Mac Casserole! Enjoy every cheesy bite with loved ones around your table!
Pro Tips for Making Big Mac Casserole
Making a delicious Big Mac Casserole is all about the little details that elevate the dish. Here are some tips to ensure your casserole turns out perfectly every time!
-
Choose the right ground beef: Using an 80/20 blend gives you that juicy, flavorful taste reminiscent of fast food burgers. Leaner meat can lead to a dryer casserole.
-
Use stale buns: Torn hamburger buns that are slightly stale actually absorb moisture better during baking, creating that perfect texture without getting soggy.
-
Don’t skip the special sauce: The combination of mayonnaise, ketchup, relish, and spices is key to achieving that iconic Big Mac flavor. Make sure to mix it well for a balanced taste.
-
Layer wisely: When assembling your casserole, try layering the ingredients carefully. This ensures even distribution of flavors and textures throughout the dish.
-
Let it rest before serving: Allowing the casserole to sit for about 10 minutes after baking helps it set up nicely, making it easier to serve and enhancing the overall flavor.
