Philly Cheesesteak Mac and Cheese

This Philly cheesesteak mac and cheese packs serious protein with an ultra-creamy cheese sauce, tender shaved beef, and caramelized peppers.

Why This Recipe Works:

• Blended Cottage Cheese: High in casein protein, it creates a stable, creamy emulsion when blended, preventing the sauce from splitting.
• Sodium Citrate Shortcut: A touch of American cheese introduces emulsifying salts that keep the cheddar perfectly smooth.
• Starch Gelatinization: Using pasta cooking water binds the fat and liquid together, ensuring the sauce clings to every noodle.

I once tried to make a healthy mac and cheese using pureed cauliflower, and it ended in tears over a gritty, grey sludge. My husband politely ate three bites before quietly reaching for the cereal box.

Talk about humiliating.

That disaster forced me to rethink how to boost protein without sacrificing the gooey stretch of real cheese. I spent weeks testing alternatives.

Most [high protein recipes](/2026/07/high-protein-recipes-burn-fat-0135.html) rely on chalky protein powders or dry, overcooked chicken breast. The texture is always off, and the cheese sauce splits into a greasy mess.

It is exhausting.

When you try to melt low-fat cheese, the protein matrix tightens too quickly, squeezing out water and leaving you with a rubbery clump. I tested this with four different light cheeses, and they all failed because they lacked the emulsifying salts needed to keep the sauce stable.

The secret lies in using cottage cheese blended until completely smooth, which serves as the foundation for our [creamy cheese sauce](/2026/07/creamy-cheese-sauce-0046.html). This creates a velvety base that mimics a traditional roux.

Trust me on this one.

We are pairing this creamy base with thinly sliced ribeye and caramelized onions. It recreates the magic of a classic [Philly Cheesesteak Skillet](/2026/07/philly-cheesesteak-skillet-9523529.html) without the heavy cream.

Ingredients

• 224g protein macaroni pasta
• 300g shaved ribeye steak, chopped
• 1 cup low-fat cottage cheese (such as Good Culture)
• 1/2 cup low-sodium beef broth
• 1/2 cup sharp cheddar cheese, shredded
• 2 slices low-fat provolone cheese, torn
• 1 medium green bell pepper, thinly sliced
• 1 medium yellow onion, thinly sliced
• 1/2 tsp Diamond Crystal kosher salt
• 1/2 tsp freshly cracked black pepper
• 1 tsp olive oil

Directions

1. Cook the protein macaroni in a large pot of salted water according to package directions, reserving 1/2 cup of pasta water before draining.
2. While the pasta cooks, blend the cottage cheese, beef broth, salt, and black pepper in a high-speed blender until completely smooth and liquid.
3. Heat olive oil in a large skillet over medium-high heat, then add the sliced onions and bell peppers, sautéing until caramelized and tender (about 6 to 8 minutes).
4. Push the vegetables to the side of the skillet, add the shaved ribeye, and sear until browned, breaking it up with a wooden spoon.
5. Reduce the heat to low, pour in the blended cottage cheese mixture, and stir in the cheddar and provolone cheeses until melted and smooth.
6. Toss the drained pasta into the skillet, adding a splash of the reserved pasta water to emulsify the sauce until it clings beautifully to the noodles.

Notes

• Salt Conversion: I highly recommend using Diamond Crystal kosher salt. If you only have fine table salt, cut the measurement in half (use 1/4 tsp instead of 1/2 tsp) to avoid over-salting.
• The Science of Cottage Cheese: Cottage cheese contains high amounts of casein protein, which is heat-stable. Blending it breaks down the curds, allowing it to melt into a seamless sauce without curdling, provided you keep the heat low.
• Workflow Warning: Do not let the cheese sauce boil once you add it to the skillet. High heat will cause the proteins in the cheddar and provolone to denature and clump, turning your smooth sauce into a gritty mess.
• Storage Behavior: Because this is a high-protein, low-fat sauce, it will thicken significantly as it cools in the fridge. When reheating, you must add a splash of milk or broth to loosen the protein matrix and restore the creaminess.

Serving Suggestions

This rich and savory mac and cheese is a complete meal on its own, but you can easily round it out with some fresh, vibrant sides to balance the decadence. Here are a few of my favorite ways to serve it:

• Crispy Green Salad: Pair it with a simple green salad tossed in a light vinaigrette to cut through the richness of the beef and cheese.
• Garlic Bread: Serve with a slice of toasted garlic bread, or try our [Steak Grilled Cheese Garlic Bread](/2026/07/steak-grilled-cheese-garlic-bread-0186.html) if you want to go all-out on the steak theme.
• Roasted Broccoli: Toss some broccoli florets with garlic and roast until charred to add a nice, smoky crunch to your plate.
• Philly Style Toppings: Top each bowl with a spoonful of pickled banana peppers or hot cherry pepper relish for an authentic, tangy kick.

Storage and Reheating

Store any leftovers in an airtight glass container in the fridge for up to three days. I do not recommend freezing this dish, as the blended cottage cheese sauce will separate and turn watery upon thawing.

It is just not worth it.

When you are ready to reheat, do not just throw it in the microwave on high power. The intense heat will shock the proteins and cause the sauce to break.

Instead, place the leftovers in a small saucepan over medium-low heat. Add a tablespoon or two of beef broth or milk, and stir constantly with a silicone spatula until the sauce becomes glossy and smooth again.

Ingredient Substitutes

If you need to swap out some ingredients based on what you have in your pantry, here are the easiest, tested substitutions:

1. The Beef: If you do not have ribeye, top round or flank steak sliced paper-thin works beautifully. You can also use lean ground beef for a budget-friendly twist, similar to our [Philly Cheesesteak Casserole](/2026/07/philly-cheesesteak-casserole-8593529.html).
2. The Cheese: If you dislike cottage cheese, you can substitute Greek yogurt, but be sure to stir it in off the heat to prevent curdling.
3. The Pasta: Any short pasta shape like penne, cavatappi, or rotini will work perfectly to catch the cheese sauce.
4. The Veggies: Feel free to add sliced mushrooms or red bell peppers to sneak in more nutrients without changing the classic flavor profile.

I hope this comforting, protein-packed bowl brings as much joy to your dinner table as it does to mine. Let me know in the comments if you try the cottage cheese trick—I promise your family won't suspect a thing!
