How to Make Big Mac Casserole

Preheat Your Oven: Start by preheating your oven to 375ºF, ensuring it’s ready for that delicious casserole.
Prepare the Hash Browns: In a large skillet, heat 2 teaspoons of olive oil over medium heat. Add 32 ounces of frozen diced hash browns, seasoning with salt and pepper to taste. Cook for about 10 minutes, tossing occasionally, until they are golden and slightly crispy.
Cook the Beef and Onions: In another large skillet, add the 2 pounds of ground beef and 1 diced white onion (reserve a handful for topping). Season with salt and pepper. Cook over medium heat until the meat is browned and no longer pink. If there’s excess grease, drain it off.
Season the Meat Mixture: Stir in 2 tablespoons of yellow mustard, 1 teaspoon of garlic powder, and 1 teaspoon of onion powder into the cooked beef. Mix for a flavorful kick.
Combine Ingredients: In a large bowl, combine the cooked hash browns with the seasoned ground beef mixture. Stir well to combine all the flavors.
Transfer to Baking Dish: Pour the mixture into a 9×13-inch baking dish, spreading it out evenly.
Add Cheese and Bake: Sprinkle 2 cups of shredded Colby Jack cheese on top. Cover the dish with aluminum foil and bake for 15 minutes.
Prepare the Big Mac Sauce: While the casserole bakes, make the Big Mac sauce by combining ½ cup mayonnaise, ½ cup ketchup, ½ cup diced dill pickles, and 2 tablespoons of dill pickle juice in a small mixing bowl. Stir until well blended.
Finish the Casserole: After 15 minutes of baking, remove the casserole from the oven. Pour the prepared sauce over the top, then sprinkle with 1 diced tomato, 1 cup of shredded iceberg lettuce, ½ cup of sliced dill pickles, and the reserved diced onion.

This dish should be served warm and gooey, perfect for serving folks you love!

Yes! Instead of ground beef, you can use a plant-based meat substitute. Combine this with extra veggies like mushrooms, zucchini, or bell peppers for added flavor and nutrition. You can also use vegetable broth for cooking the hash browns to keep the flavors cohesive.
