Step-by-Step Guide to Making Your Big Mac Casserole

Ready to begin? Just follow our straightforward guide, and you will have a bubbling, mouth-watering casserole ready in a flash. We assure you, it’s much simpler than it appears!

1. Prepare the Beef Mixture: In a large frying pan, heat a little oil over a medium-high heat. Add the beef mince along with the chopped onion. Cook, using a wooden spoon to break up the meat, until it has browned and the onion is soft. This browning process is key to developing a deep, savoury flavour. Carefully drain away any excess fat, then add the minced garlic, salt, and pepper. Continue to cook for another minute until everything is aromatic.
2. Whip Up the Special Sauce: As the beef cooks, you can prepare our incredible sauce. In a medium-sized bowl, simply combine all the sauce ingredients: mayonnaise, French dressing, sweet pickle relish, white vinegar, sugar, onion powder, and paprika. Whisk everything together until the mixture is smooth and completely blended. We recommend giving it a quick taste to see if it needs any adjustments!
3. Assemble the Casserole: First, preheat your oven to 180°C (160°C Fan / Gas Mark 4). Lightly grease a large 9×13 inch (or a similar size) baking dish. Begin by arranging half of the thinly sliced potatoes in a single layer across the bottom of the dish. Cover this with half of the cooked beef mixture. Next, drizzle over one-third of your special sauce and place 5 of the processed cheese slices on top. Repeat these layers with the remaining potatoes and beef.
4. Bake to Perfection: Sprinkle the grated cheddar cheese evenly over the final layer of beef. Cover the baking dish with aluminium foil and bake for 40-45 minutes, or until the potatoes are tender. You can test this by piercing a slice with a sharp knife. When they are ready, remove the foil and return the dish to the oven for a further 10-15 minutes, until the cheese is beautifully golden and bubbling.
5. Add the Famous Toppings: Allow the casserole to stand for around 10 minutes after removing it from the oven. This short rest helps it to set, making it much easier to serve. Immediately before you serve it, drizzle the rest of the special sauce over the top. For that truly authentic Big Mac finish, add a generous amount of shredded lettuce, sliced dill pickles, and a light scattering of sesame seeds.

Our Top Tips for Casserole Success

We are passionate about ensuring your Big Mac Casserole is the absolute best it can be. Through many delicious experiments, we have discovered a few simple tricks that will elevate this dish from merely great to truly unforgettable.

• Don’t Overcook the Mince: Bear in mind that the beef will cook further in the oven, so you only need to brown it in the frying pan. This is the secret to keeping it wonderfully juicy and tender. If you enjoy cooking with mince, we also suggest you try our recipe for Tasty Cheesy Ground Beef Stuffed Crispy Mashed Potatoes Delicious Easy.
• Slice Potatoes Thinly: Using a mandoline slicer (with caution!) is an excellent method for achieving uniformly thin slices of potato. This ensures they cook through evenly and become perfectly soft within the casserole.
• Make the Sauce in Advance: We find that the special sauce tastes even better when the flavours have had time to mingle. We suggest making it at least half an hour before you need it and allowing it to chill in the refrigerator.
• Fresh Toppings are a Must: Resist any temptation to add the lettuce or pickles before baking, as they will wilt and turn soggy. Adding them right at the end provides a cool, crisp texture that is fundamental to the classic Big Mac experience.

Fun Variations and Easy Substitutions

One of the finest qualities of a casserole is its adaptability. Please feel free to adjust this recipe to accommodate your dietary preferences or to make use of ingredients you already have on hand.

• A low-carb Big Mac casserole: For a keto-friendly alternative, you can easily replace the potatoes with layers of cauliflower florets, sliced courgettes, or even cabbage leaves. The resulting taste is just as sensational!
• Use Different Mince: Turkey or chicken mince are both fantastic leaner substitutes for beef.
• Turn Up the Heat: For those who enjoy a spicy kick, try adding some chopped jalapeños into the beef mixture or a splash of your preferred hot sauce into the special sauce.
• No Pickle Relish? No Problem: If you don’t have any sweet pickle relish in the cupboard, you can simply finely chop some gherkins and mix them with a small pinch of sugar.

Frequently Asked Questions (FAQ)

Can I make this Big Mac Casserole ahead of time?

Of course! This recipe is perfectly suited for preparing in advance. You can fully assemble the casserole (leaving off the fresh toppings) up to 24 hours beforehand. Just cover it well and store it in the refrigerator. You might need to increase the initial baking time by 10-15 minutes to account for it being cooked from cold.

How do I store and reheat leftovers?

Keep any leftovers in an airtight container in the fridge, where they will stay fresh for up to 3-4 days. To get the best results when reheating, we suggest warming individual portions in the microwave or in a preheated oven at 170°C until piping hot. Always add fresh toppings after reheating to ensure they stay crisp.

Can I freeze the casserole?

Yes, this casserole freezes very well. We advise freezing it after assembly but before it has been baked. Wrap the dish securely in cling film, followed by a layer of foil. It can be stored in the freezer for up to 3 months. When you’re ready to cook it, thaw it completely in the fridge overnight before baking according to the instructions.

What is the “special sauce” in a Big Mac?

The original McDonald’s Big Mac sauce recipe is a closely guarded secret, but it’s generally understood to be a creamy, mayonnaise-based sauce featuring sweet pickle relish, French dressing, and a blend of spices. Our homemade recipe is a wonderfully close and exceptionally tasty version of the real thing. You can find out more on the official McDonald’s UK website.
