This easy recipe combines two of our most popular camping food recipes to make a delicious leftover mac and cheese casserole.
As you may have noticed, most “leftover” mac & cheese recipes only use uncooked pasta. Hello?! How is that leftovers?!
This leftover macaroni and cheese recipe actually uses leftover cooked mac & cheese by combining two of our most popular camping recipes. Our camping mac & cheese made in an Omnia oven and our leftover hamburger casserole.
This recipe takes any leftover camping mac & cheese you have and adds it to our leftover hamburger casserole recipe. It’s a flexible recipe that you easily adjust based on the amount of leftover pasta you have.
Of course, this recipe works with any leftover mac n’ cheese, but it’s best with our homemade macaroni and cheese made in an Omnia oven.

Wait, What’s an Omnia Oven?
An Omnia oven is a Swedish stovetop oven that allows you to bake, cook, and grill delicious meals wherever (or however) you camp. It’s specially designed for gas stovetops, electric hot plates, and camping stoves.
In many ways, it’s like a lightweight Dutch oven. In fact, it’s only about 1/4 the weight of a Dutch oven of the same size.
It makes all kinds of classic comfort food, including:
- fresh bread
- roasted meat
- hashbrowns and potatoes
- calzone and pizza
- … and so much more!
That’s why we love using our Omnia oven to make our favorite mac & cheese. It’s so versatile and easy to use.
Use Your Omnia Oven to Make This Casserole
Our recipe card below explains how to make the leftover mac & cheese casserole in an RV oven, but you can also bake it in an Omnia oven. Simply substitute the casserole dish for a greased Omnia oven and cook over medium-high heat until the tater tots are golden brown.
The best thing about this easy macaroni casserole recipe is its flexibility. You can tweak it to your taste buds or whatever ingredients you have on hand.
That’s why it’ll likely become your favorite comfort food whenever you camp. You really can’t go wrong with cheesy flavor and tater tots, right?!
- The recipe calls for cheddar cheese, but you can play with the combination of cheeses to complement your leftover mac and cheese. Feel free to experiment with different types of cheese, like, Monterey jack, pepper jack cheese or parmesan cheese.
- For extra flavor and a spicier kick, add a sprinkle of chili powder or black pepper to the cream of mushroom soup or ground beef as you brown it.
- It goes great with a variation of sauces, including BBQ sauce, sour cream, and ranch dressing.
Leftover Mac and Cheese Casserole
We hope you enjoy this delicious mac casserole as much as we do. Combining cheesy pasta with tater tots is like using super bread crumbs. It balances the creamy macaroni with a salty texture.

Still Have Leftovers?
Having leftovers of leftover casserole may not sound appetizing, but it actually reheats quite well. For best results, mix in some extra cheese before you reheat. Or you can add a sauce, like BBQ sauce or ranch dressing.
If reheating in a microwave, it helps to sprinkle a little water on top or place a glass of water in the microwave as it reheats. That’ll help prevent the microwave from drying it up.
So, if you have any leftovers, store them in an airtight container in the fridge and enjoy them the next day.
