1. Crank your oven to 375°F (190°C) and grease a 9×13-inch casserole dish. Cook your macaroni according to package directions, drain it, and set it aside.
2. In a large skillet over medium heat, brown the ground beef, breaking it up as it cooks. When it’s almost all browned, add the diced onions and minced garlic. Cook until the onions are translucent—about 5 minutes.
3. Drain off any excess grease if you’ve got more than a tablespoon sitting in the pan.
4. Stir in the diced tomatoes, ketchup, mustard, salt, and pepper. Let this simmer for about 5 minutes so everything can get friendly with each other. You want it to thicken slightly and smell amazing.
5. Time to layer! In your prepared casserole dish, spread half of the cooked macaroni on the bottom. Top it with half of the beef mixture, then sprinkle half of the shredded cheddar over that.
6. Repeat the layers with the remaining macaroni, beef mixture, and cheese. You should end with cheese on top.
7. Cover the dish with foil and bake for 20 minutes. Then remove the foil and bake for another 10 minutes until the cheese is melted, bubbly, and getting those golden edges.
8. Pull it out of the oven and immediately sprinkle those diced pickles all over the top. This is what makes it taste like an actual cheeseburger!
9. Let it cool for about 5 minutes before serving (if you can wait that long).

This is comfort food with a good amount of protein from the beef and cheese. The pasta adds carbs for energy, and you’re getting some veggies from the tomatoes and onions.

Notes:

• Make sure to cook your pasta before assembling. Uncooked pasta won’t get tender in the oven.
• Drain that ground beef well or you’ll have grease city happening.
• Don’t skip the pickles! They’re what make this taste authentically burger-like.
• Every oven runs differently, so check at 30 minutes total baking time to make sure you’re not overcooking.

Storage Tips:

Store leftovers covered in the fridge for up to 4 days. Reheat individual portions in the microwave for 2-3 minutes, or reheat the whole thing covered in a 350°F oven for about 20 minutes. This actually freezes beautifully—wrap individual portions in foil and freeze for up to 3 months. Thaw in the fridge overnight before reheating.

Serving Suggestions:

• With a simple green salad to balance all that comfort food richness
• Alongside BBQ baked beans for the ultimate cookout-style meal
• With sweet potato fries or regular fries if you want to go full burger experience
• With coleslaw for that classic burger-and-slaw combo

Mix It Up (Recipe Variations):

Bacon Cheeseburger Casserole: Cook 6 strips of bacon until crispy, crumble, and sprinkle over the top with the pickles.

Mushroom Swiss Burger Casserole: Use Swiss cheese instead of cheddar and add 8 oz sliced mushrooms cooked with the onions.

BBQ Bacon Cheeseburger Casserole: Replace the ketchup with BBQ sauce and add crumbled bacon for a smoky twist.

Loaded Cheeseburger Casserole: After baking, top with sour cream, extra diced pickles, diced tomatoes, and shredded lettuce.

What Makes This Recipe Special:

This recipe transforms the beloved American cheeseburger into a practical, family-friendly casserole that’s easier to serve to a crowd than individual burgers. By layering pasta with seasoned beef and cheese, then baking until bubbly, you create a dish where all those classic burger flavors—the tangy ketchup-mustard sauce, melted cheddar, and crunchy pickles—come together in every forkful. The casserole format makes it perfect for busy weeknights, potlucks, or feeding a group, while still delivering that satisfying burger experience everyone craves.
