Ingredient Notes
Potatoes
- Olive oil
- Russet potatoes: Some versions of this casserole call for crispy tater tots. Feel free to substitute if desired. I prefer diced potatoes as they are healthier and fresher and still have the "french fry" feel.
- White onion
- Minced garlic
- Chicken broth
- Paprika
Burger Meat
- Lean ground beef: Alternatively, you can substitute ground turkey if desired.
- Onion powder
- Garlic powder
- Paprika
- Salt
- Black pepper
Remaining Ingredients
- Shredded cheddar cheese
- Cherry tomatoes: Big Macs don't typically feature tomatoes so feel free to omit if desired.
- Shredded lettuce
- Dill pickle chips
- Diced white onion
- Cooked bacon: optional
- Big Mac Sauce: Ingredients include Greek yogurt or mayonnaise, yellow mustard, pickle relish, ketchup, coconut aminos, salt, and paprika.
How To Make Big Mac Casserole
Step 1
Preheat oven to 375. Add oil to a large skillet over medium-high heat. Add onions & garlic and stir for 2-3 mins.
Step 2
Add onions & garlic and stir for 2-3 mins. Then, add diced potatoes and spices. Finally, add chicken broth. Cook for 10-15 mins, stirring often, until browned and softened.
Step 3
Add them to the bottom of a 9×13-inch casserole dish.
Step 4
Next, cook the ground beef & spices until cooked through. Drain the excess grease. Pour the ground beef mixture into the baking dish on top of the potatoes.
Step 5
Add the shredded cheese on top and bake for 15 minutes until the top of the casserole is golden brown. While it's baking, make your Big Mac sauce.
Step 6
Top the casserole with some lettuce.
Step 7
Next add the tomatoes, pickles, and chopped onion.
Step 8
Lastly, add a drizzle of the Big Mac Sauce!
Expert Tips
- To save time, you can cook the potatoes and ground beef at the same time using 2 different pans, OR air fry the potatoes tossed with oil and spices for 15 mins at 400, tossing often, while you cook the beef.

Storage Tips
Store leftovers in an airtight container in the fridge for up to 3-4 days. Reheat in the microwave or oven and serve warm.
I don't recommend freezing, as the fresh veggies will not hold up well in the freezer. You can freeze the sauce or the ground beef and potato mixture for later use. Thaw in the refrigerator overnight and use when ready to make your casserole.
Recipe FAQs
In my high protein version, I use Greek yogurt, yellow mustard, pickle relish, ketchup, coconut aminos, salt, and paprika. If desired, you can use Worcestershire sauce instead of coconut aminos, but keep in mind that it's not gluten-free so you'll need to find a gluten-free version.
A Big Mac features a bun topped with sesame seeds, shredded iceberg lettuce, dill pickles, Big Mac sauce, white onion, cheese, two burger patties, and an extra bun in the middle. It does not have tomatoes, but I added them to this recipe because I like tomatoes with my burgers!

So good. I’ve made it multiple times and I don’t deviate. Definitely make the sauce too! I keep the toppings on the counter and everyone can top their own in taco bar style serving. It’s great for meal prep.
This was a huge hit with my family. It definitely took me more than 30 minutes to make with the chopping but I’ll try to do that ahead of time next time.
This is delicious! How do you finish this in 30 minutes though? It takes me 1.5 hours and I’ve made it several times already, lol
My kids ask for this one regularly. It is easy and tastes great.
I made this last night. My family loved it. No leftovers and the sauce was amazing. They said it was one of the best meals I have made. Thank you for an easy recipe.
So glad to hear it, Mary! Thanks!
There are no tomatoes in a Big Mac LOL
Hi! What is the serving size for this meal? We ate it tonight and really liked it!
Hi! It’s 1/6 of the total recipe! You basically just have to eyeball it and visually divide the total casserole into 6 parts.
As I write this I am eating this Big Mac casserole and it’s delish! Very easy to make and truly gives you that fix of a fast food burger but of course so much better for you! Since we are talking Big Mac I sprinkled mine with sesame seeds! Will be making this again! Thanks Mary!
Thanks Kathy!
Hi! I’m planning on making this tonight and was curious if the nutritional info is based on dill pickle chips, or just sliced dill pickles. Your photos seem to have jarred pickles, and the instructions state to add pickles as a topping. Yet the ingredients list dill pickle chips. Can you please clarify? Thanks!
round pickle slices aka pickle chips are what I used for the nutrition info! It’s the same both ways – the recipe just calls for pickles…whether diced or in chip form.
Huge family hit right here. We used actual Chic fila sauce and I crumbled on fresh crispy bacon but otherwise such a winner and easy sell for the entire family (picky eaters included).
Thank you!
