This burger puts a scoop of sharp-cheddar mac and cheese directly on the patty — both under it and on top. It takes about an hour start to finish and makes four substantial burgers. The real reason to make it: the mac and cheese recipe produces more than you need for one meal, so you get a head start on the rest of the week.
About the ingredients
- Ground beef (80/20): The fat ratio matters here. Leaner beef dries out fast on a hot skillet, and you’re not adding any sauce to the patty itself.
- Mustard powder: This is a pantry staple worth keeping around. It sharpens the cheese sauce without tasting like mustard. Don’t substitute prepared mustard — it adds too much liquid and changes the texture.
- Nutmeg: Listed as optional, and it genuinely is. Leave it out if you don’t have it; the sauce works fine without it.
- Brioche buns: These hold up better than standard burger buns under the weight and moisture of the mac and cheese. A potato roll is a solid swap if brioche isn’t available.
- Sharp cheddar: Used in both the sauce and as a melt on the patty. Grate it yourself — pre-shredded cheese has anti-caking coatings that make the sauce slightly grainy.
What makes this version work
The mac and cheese is built on a proper roux — butter and flour cooked together before the milk goes in. That step is what keeps the sauce thick enough to sit on a burger without running straight off the bun. If you rush it and add cold milk all at once, you get a thin, watery sauce that soaks the bottom bun before anyone takes a bite. The other thing that matters: pressing a shallow indent into the center of each raw patty. Ground beef contracts as it cooks, and without that indent the middle puffs up into a dome that makes the mac and cheese slide off.
What can go wrong
- Sauce seizes and goes lumpy: This happens when the heat is too high when you add the cheese. Pull the pan off the burner entirely, then stir the grated cheese in off the heat. Residual warmth is enough to melt it smoothly.
- Mac and cheese stiffens before assembly: Pasta keeps absorbing the sauce as it sits. If you made it ahead, stir in a splash of warm milk before serving to loosen it back up.
- Patties hit 160°F (71°C) too fast on the outside but stay raw inside: This usually means the pan is too hot. Medium-high heat is the ceiling. A meat thermometer is the only reliable check — color alone isn’t accurate for ground beef.
- Bun goes soggy immediately: Toast the cut sides in the same skillet after the patties come out. Thirty seconds is enough to create a barrier against the sauce.
- Burgers fall apart during assembly: The mac and cheese layer is heavy. Build the burger on the plate, not in your hand, and serve it right away rather than letting it sit assembled.
Keeping and reheating
Store the mac and cheese and the cooked patties separately in airtight containers in the fridge — both keep well for up to four days. The mac and cheese actually reheats better than most pasta dishes because the roux-based sauce re-emulsifies cleanly: add a small splash of milk, cover loosely, and microwave in 60-second intervals, stirring between each. The patties reheat best in a covered skillet over low heat with a tablespoon of water to create a little steam; this takes about three minutes and keeps them from drying out. Assembled burgers don’t store well — the bun turns to mush within an hour. For freezing, the cooked patties freeze fine for up to three months; the mac and cheese can be frozen but the texture softens noticeably, so refrigerating it is the better call for weekly use.
Mac and Cheese Burger
Ingredients
Burger Ingredients
- 500 grams ground beef preferably 80/20 lean-to-fat ratio
- 1 teaspoon salt sea salt preferred
- ½ teaspoon ground black pepper freshly ground
- 4 slices cheddar cheese sharp
- 4 medium burger buns brioche
Mac and Cheese Ingredients
- 200 grams macaroni elbow pasta
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 cup milk whole
- 1 ½ cups cheddar cheese, grated sharp
- 1 teaspoon mustard powder
- ¼ teaspoon nutmeg freshly grated, optional
Instructions
Prepare the Mac and Cheese:
- Cook the macaroni in a pot of boiling salted water until al dente, approximately 8 minutes. Drain and set aside.
- In a separate saucepan, melt the butter over medium heat, then whisk in the flour to form a roux. Gradually add the milk, whisking continuously until the mixture thickens.
- Add the grated cheese, mustard powder, and optional nutmeg, stirring until the cheese is melted and the sauce is smooth. Combine with the cooked macaroni.
Prepare the Burgers:
- In a bowl, gently combine the ground beef with salt and pepper. Form into 4 patties, pressing slightly in the center to prevent puffing during cooking.
- Heat a skillet or grill over medium-high heat. Cook the patties for about 4 minutes on each side for medium doneness, or until your desired level is reached. Place a slice of cheese on each burger during the last minute to melt.
Assemble the Burgers:
- Toast the buns lightly. Place a scoop of mac and cheese on the bottom bun, followed by the burger patty. Add another layer of mac and cheese on top, then the top bun.

Your questions, answered
Can I make the mac and cheese a day ahead?
Yes, and it actually works well that way. Refrigerate it in an airtight container and stir in a splash of warm milk when you reheat it — the sauce will loosen back to the right consistency in a couple of minutes.
How do I know when the burger patties are done?
Use a meat thermometer and pull them at 160°F (71°C) internal temperature — that’s the safe minimum for ground beef. The four-minutes-per-side guideline in the recipe is a reasonable estimate, but pan temperature and patty thickness vary enough that a thermometer is the only way to be sure.
Can I cook the patties in batches and reheat them later in the week?
Yes. Cook all four patties fully to 160°F (71°C), cool them quickly, and refrigerate separately from the mac and cheese. Reheat in a covered skillet with a splash of water over low heat for about three minutes — they stay juicier than they would in a microwave.
What’s the best way to stop the mac and cheese from sliding off the burger?
Let the mac and cheese cool for five minutes after cooking so it thickens slightly before you scoop it onto the bun. A thicker, slightly cooled sauce clings rather than runs.
Can I double the mac and cheese recipe?
Easily — it scales well. A doubled batch gives you enough for the four burgers plus two or three additional side servings during the week, which is worth the minimal extra effort since you’re already making the roux.
