The Most Authentic Creamy High Protein Mac and Cheese Recipe
You won’t believe how simple it is to create a homemade version that’s not only delicious but also bursting with protein. This creamy high-protein mac and cheese will have your family asking for seconds, and you can feel good about serving it.
Ingredient Notes
– Elbow Macaroni: The classic choice for comfort, this pasta holds the cheese sauce beautifully.
– Full-Fat Cottage Cheese: This is an essential ingredient for adding both creaminess and protein to the dish without being overly rich.
– Whole Milk: A must for achieving that smooth, creamy texture — don’t skip it for low-fat varieties.
– Sharp Cheddar: Freshly grated is crucial; pre-grated cheese can contain anti-caking agents that affect meltability.
– Smoked Paprika: Just a little sprinkle will enhance the flavor profile, adding a subtle smokiness that complements the cheesy goodness.
Instructions
Step 1: Boil and Cook
Begin by bringing a large pot of water to a rolling boil, then add kosher salt and elbow macaroni. Cook until the pasta reaches al dente, according to the package instructions, and be sure to reserve some of that starchy pasta water before draining.
Step 2: Whisk and Heat Milk
In a medium saucepan, whisk together the arrowroot powder and whole milk until smooth. Gently heat the mixture over medium-low heat, stirring frequently until it starts to steam, ensuring it does not boil.
Step 3: Blend the Sauce
Remove the saucepan from heat and stir in the cottage cheese, Dijon mustard, garlic powder, smoked paprika, and black pepper. Use an immersion blender to puree the mixture until it’s velvety and smooth.
Step 4: Incorporate Cheese
Return the saucepan to very low heat. Gradually add the grated cheddar in two batches while whisking. Make sure to incorporate the cheese completely until melted, adding some reserved pasta water if the sauce thickens up too much.
Step 5: Combine Pasta and Sauce
Taste the cheese sauce and adjust the seasoning with salt and additional black pepper if needed. Fold the drained pasta into the sauce gently until every noodle is fully coated. If it feels tight, a splash of the reserved pasta water can help loosen it up.
Step 6: Rest and Serve
Allow the mac and cheese to sit off the heat for a few minutes to thicken the sauce and help the flavors meld. Serve warm, garnished with a touch more black pepper or a sprinkle of cheddar if desired.
Tips and Mistakes to Avoid
– Don’t skip reserving the pasta water; it’s key for adjusting sauce consistency.
– Make sure to blend the sauce well, as lumps from cottage cheese won’t melt into the sauce.
– When adding cheese, taking the saucepan off heat ensures it melts smoothly without separating or becoming grainy.
Storage Tips
Store leftovers in an airtight container in the fridge for up to three days. You can also freeze it for longer storage — just be sure to reheat slowly to maintain creaminess. This dish is great for meal prep; simply portion it out and pop it in the fridge for easy grab-and-go lunches.
Variations and Substitutions
For a higher protein option, you could swap in whole grain pasta, which adds more fiber and protein. If you’re looking to lighten things up, consider using low-fat cottage cheese instead of full-fat. There’s also the option to mix in veggies like spinach or broccoli to sneak in extra nutrients.
Why This Recipe Is The Real Deal
What really sets this mac and cheese apart is the creamy base, thanks to the cottage cheese and the whole milk that elevates the dish beyond just comfort food. It’s a great way to sneak in high protein without sacrificing the comforting flavors everyone loves. Personally, I appreciate that it gives my family the nutrition they need without feeling like a chore to make at the end of a long day.
The Bottom Line
This creamy high-protein mac and cheese is not just another side dish; it’s a full meal that your whole family will love. Try it, and you won’t be disappointed — I’d love to hear what you think!

Creamy High Protein Mac and Cheese
Ingredients
Pasta
- 9 oz elbow macaroni
- 1 tsp kosher salt (for cooking pasta)
Cheese sauce
- 1 cup full-fat cottage cheese
- 1 cup whole milk
- 1 cup freshly grated sharp cheddar
- 1 Tbsp arrowroot powder (or cornstarch)
- 1 tsp Dijon mustard
Seasonings
- 3/4 tsp garlic powder
- 1/2 tsp smoked paprika
- 1/2 tsp freshly ground black pepper
- salt, to taste
Instructions
Preparation Steps
- Bring a large pot of water to a rolling boil, add the 1 tsp kosher salt, then drop in the elbow macaroni. Cook until al dente according to package directions (usually about 7–9 minutes). Before draining, scoop out and reserve 1/2 cup of the starchy pasta cooking water, then drain the pasta and set aside.
- While the pasta cooks, whisk together the arrowroot powder and whole milk in a medium saucepan until smooth (no lumps). Heat the milk mixture gently over medium-low, stirring frequently, until it just begins to steam — do not boil.
- Remove the pan from the heat and add the cottage cheese, Dijon mustard, garlic powder, smoked paprika, and black pepper. Using an immersion blender, puree the mixture in the saucepan until it becomes a smooth, velvety sauce. (If you don’t have an immersion blender, transfer to a countertop blender in batches and blend until smooth, then return to the pan.)
- Return the pan to very low heat. Add the grated cheddar in two batches, whisking well after each addition until the cheese is melted and the sauce is homogenous. If the sauce seems too thick, whisk in up to 1/4–1/2 cup of the reserved pasta water a tablespoon at a time to reach your desired consistency.
- Taste the sauce and adjust seasoning with salt and more black pepper as needed. Transfer the drained pasta to the saucepan and gently fold with the cheese sauce until every noodle is coated. If the mixture tightens up, stir in a splash of the reserved pasta water.
- Let the mac and cheese sit off the heat for 3–5 minutes so the sauce can thicken and the flavors meld. Serve warm with an extra crack of black pepper or a light sprinkle of grated cheddar if desired.
