Cottage Cheese Mac and Cheese (Creamy, High Protein, 25 Minutes)

This cottage cheese mac and cheese is the recipe that finally got a high protein dinner past my kids without a single complaint: a full cup of cottage cheese gets blended completely smooth with milk and Dijon, stirred into a quick cheddar sauce, and nobody at the table can taste it — they just taste creamy mac and cheese. It takes 25 minutes, lands 31g of protein a serving, and it has quietly replaced my baked mac and cheese on weeknights, right alongside the cottage cheese alfredo and cottage cheese gnocchi that started this whole cottage cheese habit.

Why this high protein mac and cheese actually tastes like mac and cheese.

• The cottage cheese gets blended, not stirred. Thirty seconds in the blender turns cottage cheese, milk and Dijon into a sauce as smooth as heavy cream. No curds, no grainy texture, no tang — just body and protein. It’s the same trick behind my cottage cheese alfredo pasta, and it is non-negotiable.
• Real sharp cheddar still does the flavor. This is not a diet mac and cheese that tastes like one. A full two cups of sharp cheddar melt into the blended base, so you get that proper orange, stretchy, tangy cheese pull — the cottage cheese just means you need less of it for the same creaminess, which is where the high protein mac and cheese numbers come from.
• 25 minutes, one pot and a blender. The sauce comes together while the pasta boils, and the optional panko top takes 3 minutes under the broiler. It is faster than my crockpot mac and cheese and lighter than the baked version, which makes it one of the easiest high protein meals on the site.

Here's what you'll need.

Ten ingredients, all ordinary: elbow macaroni, full-fat cottage cheese, milk, sharp cheddar, a little butter and flour, Dijon mustard, garlic powder and smoked paprika, plus panko and parmesan for the crunchy top.

Here's how it all comes together.

STEP 1 — Cook the pasta a minute short.

Boil the elbows in well-salted water until just shy of al dente — they finish in the sauce. Scoop out a cup of the starchy pasta water before you drain them; it is your insurance for a silky sauce.

STEP 2 — Blend the cottage cheese smooth.

While the pasta cooks, blend the cottage cheese, milk, Dijon, garlic powder and smoked paprika on high for 30 to 45 seconds until completely smooth with no visible curds. Scrape the sides once and blend again.

STEP 3 — Make a quick roux and add the base.

In the same pot, melt the butter over medium heat, whisk in the flour and cook 1 minute. Pour in the blended cottage cheese mixture while whisking and bring it to a gentle simmer until it thickens slightly, 2 to 3 minutes.

STEP 4 — Melt in the cheddar off the heat.

Pull the pot off the heat and add the cheddar a handful at a time, stirring until each addition melts before adding the next. Off the heat is the trick — boiling cheddar turns greasy and stringy.

STEP 5 — Fold in the pasta.

Add the drained elbows and stir until every piece is coated. If the sauce is thicker than you like, loosen it with a splash of the reserved pasta water. Taste for salt — cheddar varies.

STEP 6 — Top with panko and broil.

Optional but worth it: toss the panko with parmesan and a teaspoon of melted butter, scatter it over the top and broil 2 to 3 minutes until golden. Watch it — it goes from golden to burnt fast.

Things I learned while testing this recipe.

• Full-fat cottage cheese, small curd. Low-fat cottage cheese blends thinner and tastes more sour; 4% small curd gives a sauce that is rich and neutral. Good Culture, Daisy and Kalona all blended perfectly in testing.
• Shred your own cheddar. Pre-shredded cheese is coated in starch that keeps it from melting smoothly. A block of sharp cheddar and a box grater takes 2 minutes and makes a noticeably silkier sauce.
• Do not let the sauce boil after the cheese goes in. Cheddar breaks above a simmer. Melt it off the heat, and if you need to rewarm the sauce, do it low and slow.
• Save the pasta water. Every batch thickens a little differently. A few spoonfuls of starchy water turn a slightly stiff sauce back into a glossy one without thinning the flavor.

Why this is the high protein dinner I keep coming back to.

• 31g of protein in a bowl of mac and cheese. Regular mac and cheese lands around 15g a serving. Blending in a full cup of cottage cheese and using protein-fortified or regular pasta pushes it to 31g, which turns a side dish into a real protein target hitter.
• It is a meal prep lunch that reheats well. Because the sauce is cottage-cheese based rather than pure cheddar, it stays creamy after a night in the fridge instead of setting into a brick. Portion it into containers with a splash of milk on top.
• Easy to turn into a full dinner. Stir in shredded rotisserie chicken, leftover baked chicken meatballs or steamed broccoli and you have a one-bowl dinner with even more protein.

Here's what I'd serve with this.

• Air fryer chicken tenders — crispy, kid-approved and done in the time it takes the pasta to boil
• Roasted cauliflower — a little char and lemon to balance all that cheese
• Air fryer brussels sprouts — crispy edges, 15 minutes, no oven competition
• Garlic butter chicken bites — spoon them right over the top for a 50g-protein bowl
• Mediterranean baked cod — today’s other new recipe — a lighter, 25-minute dinner for the next night

Just in case you have leftovers.

Storing: Cool completely and refrigerate in an airtight container for up to 4 days. It thickens as it chills; that is the pasta soaking up sauce, not the sauce going wrong. I do not recommend freezing it — cottage cheese sauces separate once thawed.

Reheating: Add a generous splash of milk, cover and warm in a skillet over medium-low, stirring now and then, for about 5 minutes, or microwave at 70% power in 60-second bursts with a spoon of milk stirred in between. Avoid high heat, which makes the cheddar oily.
