🥣 Instructions

This is an overview of the recipe steps. For more detailed instructions visit the recipe card at the bottom of this post.

• Step 1: Heat the olive oil in a large skillet over medium-high heat. Cook the hash browns for about 5-10 minutes, until golden brown then add to a 9x13" baking dish.
• Step 2: Add the juicy ground beef and white onions to the same skillet and cook until no more pink remains.
• Step 3: Drain the fluid, then add mustard and seasonings.
• Step 4: Empty into the casserole dish with the hash browns and mix together.

• Step 5: Sprinkle the shredded cheese all over the top. Mix some in if you like.
• Step 6: Cover with aluminum foil and bake for 15 minutes.
• Step 7: While the Big Mac Casserole is baking, mix together the delicious Big Mac Sauce (that's a special sauce). Add the ketchup, mayonnaise, chopped pickles and pickle juice to a small mixing bowl, and mix together.
• Step 8: Remove the casserole from the oven and pour the sauce over the top.
• Step 9: Add the toppings on top of the hamburger casserole for serving.

💡 Tips

Expert Tip: To reheat this Big Mac Casserole remove the toppings first. Reheating in the microwave will be best so as not to dry it out. Then add the toppings back.
