How to Make Big Mac Casserole Recipe

Step 1: Brown the Beef and Onion

Start by heating a skillet over medium heat and add your ground beef along with the diced onion. Cook until the beef is completely browned and the onions are soft and translucent. Then, drain any excess fat to keep the casserole from getting greasy while locking in that rich flavor.

Step 2: Season the Mixture

Once you have that beautifully browned beef, stir in the salt, pepper, garlic powder, and paprika. These seasonings work together to transform simple ingredients into a tasty filling with layers of flavor that remind you of a classic cheeseburger.

Step 3: Assemble the Casserole

Spread your savory beef and onion mixture evenly into a baking dish. Then generously top it with shredded cheddar cheese so it will melt into a gorgeous golden layer during baking.

Step 4: Bake to Perfection

Pop the casserole into a preheated 350°F oven and bake for about 15 minutes, or until the cheese is bubbling and golden. This short baking time ensures everything melds perfectly while keeping the beef juicy.

Step 5: Prepare the Special Sauce

While the casserole is baking, whisk together mayo, ketchup, mustard, vinegar, and sweetener if you want a touch of sweetness. This sauce will bring that signature Big Mac tang and creaminess that ties the dish together.

Step 6: Add Final Toppings

Once out of the oven, top your casserole with diced pickles and shredded lettuce. Drizzle or dollop the special sauce on top just before serving for the ultimate Big Mac experience in casserole form.

Make Ahead and Storage

Storing Leftovers

Leftover Big Mac Casserole keeps beautifully in an airtight container in the fridge for up to 3 days. The flavors actually meld more over time, making the next-day lunch just as delicious as dinner.

Freezing

You can freeze this casserole before baking or after it’s cooked. Just cover tightly with foil and freeze for up to 2 months. Thaw overnight in the fridge before reheating for best results.

Reheating

Reheat individual portions in the microwave or warm the whole casserole in the oven at 350°F until heated through and the cheese is melty again. Adding fresh toppings after reheating brings back the brightness and crunch.

FAQs

Can I make this recipe gluten-free?

Absolutely! The Big Mac Casserole Recipe contains no gluten-containing ingredients by default. Just double-check your condiments like ketchup and mustard to ensure they are gluten-free for a perfect fit.

Is this recipe suitable for keto or low-carb diets?

Yes, it’s a great low-carb alternative to a classic Big Mac since it skips the buns and relies on fresh veggies and high-fat ingredients. Using sugar-free ketchup and mayo keeps it keto-friendly too.

Can I add other veggies to the casserole?

Definitely. Shredded cabbage or chopped bell peppers mix in wonderfully for extra crunch and color. Just sauté any additional veggies with the beef and onion first for best texture.

What can I use instead of ground beef?

Ground turkey or chicken can be swapped in for a lighter version, though beef’s flavor is the classic choice that best mimics a Big Mac’s bold taste.

How spicy is this dish?

This casserole is mild and family-friendly. The paprika adds subtle smokiness rather than heat, so everyone can enjoy it. Feel free to add a pinch of cayenne pepper if you like a little kick.
