Let’s just say it: Steak Mac and Cheese is the kind of dish that makes grown men tear up with joy.

This is not your average boxed dinner—it’s the ultimate comfort food, leveled up, grilled over open flames, and finished with a buttery crust that’ll have you saying “that’s so freakin’ delicious!”

Steak Mac and cheese is baked and ready to serve.

This mashup of smoky grilled sirloin steaks (or your favorite steaks) with bubbling, sharp cheddar cheese mac is the kind of recipe that turns weeknights into feasts and cookouts into legends. So grab your sturdy skillet, fire up the grill, and get ready to throw down something fierce.

Why You’ll Love Steak Mac and Cheese

This ain’t just any cheese recipe—it’s a meat lover’s dream mixed with every cheesy fantasy you’ve ever had. This recipe is a riff on a loaded mac n cheese, only we’ve gone ahead and stuffed it with steak and bacon because… why not?

The layers of flavor hit you in waves: First, the smoky, seared steak slices seasoned with a bold Cowboy Butter Rub. Then the gooey cheese blend that combines sharp cheddar and mozzarella—two cheeses that work overtime in the flavor and melt departments. Add some bacon bits for salt and crunch, and top the whole thing off with a quick bake or grill finish to develop that craveable crust.

How to Make Steak Mac and Cheese

Grill That Steak

Start by slathering your sirloin steaks (or preferred cut) in a little canola oil, then hit ‘em hard with the Cowboy Butter Rub. Preheat your grill to high heat (400F). Sear those steaks for 2–3 minutes per side until they hit about 120F internal for a perfect medium-rare. Pull them off, rest for a couple minutes, then slice into bite-sized steak pieces. Set aside, try not to eat them all.

Build the Cheese Sauce

Next up, the heart of this cheese recipe. Place a sturdy skillet on the grill over medium-low heat. Melt your butter and whisk in the flour to create a roux—this should take 1-2 minutes, stirring constantly so it doesn’t burn.

Making the rue for the steak Mac and cheese.

Add in your Cowboy Butter Rub and give it all a stir. Slowly pour in about 75% of your whole milk, whisking as you go to keep things smooth. Once that sauce is looking thick, add the Dijon mustard for a bit of tang and kick. Now it’s time for the stars—fold in your shredded sharp cheddar and mozzarella. Stir until melted and smooth, then thin it out with the rest of your milk as needed.

Pro Tip

If the sauce becomes too thick, save a little pasta water from earlier and stir it in.

Assemble the Mac

Grab a second cast iron or grill-safe skillet and add your cooked elbow macaroni. Pour in about two-thirds of that cheese sauce and give it a good mix. Now pile on the steak pieces, sprinkle in those bacon bits, and top the whole thing with more shredded cheese and remaining sauce. No such thing as too much cheese for our steak mac and cheese.

Bake or Grill to Finish

Throw the skillet into your grill or oven at 400F for 10-15 minutes until the top is bubbling and starts to brown just slightly. You’re looking for that golden crust—not burnt, but not soft either. Pull it off, top with a bit of fresh parsley, and get ready to dig in.

What to Serve with Steak Mac and Cheese

If you want to turn this into a full-blown feast, pair it with a crisp grilled Caesar salad, some garlic bread, or even a grilled veggie skewer if you’re feeling balanced (or pretending to be). A cold beer or bourbon cocktail won’t hurt either—this is a heavy hitter of a dish and deserves a worthy sidekick.

The final dish ready to serve.

For an extra touch of indulgence, serve it up with some fried pickles, onion rings, or one of those yummy looking recipes you’ve bookmarked and never made. Now’s the time.

Leftovers & Reheating Instructions

Store any leftover steak Mac and cheese in an airtight container in the fridge for up to 3 days. When it’s time to reheat, the best method is the stovetop over medium heat, stirring frequently and adding a splash of milk or pasta water to loosen things up.

Microwave? It’ll do in a pinch. Just heat in 30-45 second bursts, stirring between each round until warm. Whatever you do, don’t overheat it—nobody likes rubbery steak or separated cheese sauce.

Steak Mac and Cheese FAQs

Can I skip the final bake step?

Yes! If you’re short on time (or just hungry), you can serve the mac straight after mixing. That creamy cheese sauce and juicy steak bites are still going to blow minds, even without the baked crust.

What’s the best steak to use for this?

You can’t go wrong with a well-marbled NY strip steak, but sirloin, ribeye, or even leftover steak works. Just slice it thin and make sure it’s cooked medium or less so it doesn’t dry out when reheated.

Can I make this ahead of time?

You bet. Prep the mac and cheese and grill the steak ahead of time, store both separately, then reheat and assemble when you’re ready. It’s a great way to save time and still get full flavor.

  1. Love this recipe! You might want to add the flour to the skillet in step one to complete the roux…..seem that step is missing from the instructions?
