Cottage Cheese Pasta Sauce, and the Blender Trick That Replaced Cream

This is a fifteen-minute pasta with no cream in it. The sauce is cottage cheese, parmesan, and a splash of starchy pasta water, blended until it is completely smooth, and it coats rigatoni the way a cream sauce does. Each serving lands at about 30 grams of protein, and below I show exactly where those grams come from, because the number only holds if you use the amounts in the card.

I first saw this idea in a food documentary, where a well-known New York chef (I have long since forgotten his name) folded cottage cheese into pasta and other Italian dishes. At home I use Costco’s Kirkland cottage cheese. I’ll be honest about the taste: it is not a cream sauce. Cream pasta is heavier, softer, and richer in fat; this is cleaner and brighter, but it still has real flavor.

Ingredient Notes

Cottage cheese, 4% milkfat. Full-fat blends the smoothest. 2% works. Nonfat tends to turn grainy and can split when it meets heat. Brands differ in salt and curd size, so hold the salt until you taste the finished sauce.

Why blending works. Cottage cheese curds are milk protein (mostly casein) that has been set and cut into pieces. A blender breaks those curds back into a fine, even paste, and the pasta water’s starch keeps that paste loose and glossy instead of stiff.

Pasta water. Save a full cup before you drain. You will use about half in the blender and the rest to loosen the sauce in the pot.

Parmesan. Grate it finely so it melts into the sauce rather than clumping. It also adds about a sixth of the protein.

No blender? An immersion blender or a small food processor both work. Mashing with a fork does not; the curds stay.

Cottage Cheese Pasta Sauce

Serves 2 · Prep 5 min · Cook 12 min · Total 15 min · Dinner · American

Ingredients

• 6 oz (170 g) dried pasta (rigatoni, penne, or spaghetti)
• 1 cup (225 g) cottage cheese, 4% milkfat
• ½ cup (40 g) finely grated parmesan, plus more to serve
• 1 clove garlic
• Zest and juice of ½ lemon
• ½ tsp black pepper and ¼ tsp salt, to taste
• 3 cups (90 g) baby spinach
• 1 Tbsp olive oil

Instructions

1. Cook the pasta in well-salted water. Before draining, save 1 cup of the cooking water.
2. Blend the cottage cheese, parmesan, garlic, lemon zest and juice, pepper, and ½ cup of the pasta water until completely smooth, about 45 seconds.
3. Warm the olive oil in the empty pasta pot over low heat. Add the spinach and stir until just wilted.
4. Add the pasta and the sauce. Toss over low heat for 1 minute, loosening with more pasta water as needed. Do not let it boil.
5. Serve with more parmesan and pepper.

Per serving (estimated from USDA FoodData Central values): about 520 kcal · 30 g protein · 68 g carbohydrate · 14 g fat · 4 g fiber · about 780 mg sodium. Where the protein comes from: cottage cheese about 13 g, parmesan about 5 g, pasta about 10 g, spinach the rest. With ¼ cup parmesan instead of ½ cup, it drops to about 27 g.

Make It Yours

• Lemon and garlic is the base version above.
• Sun-dried tomato and basil: blend 4 sun-dried tomatoes into the sauce and finish with torn basil.
• A little heat: blend in 1 tsp gochujang, the same way we used it in last week’s noodles.
• More protein: fold in sliced chicken breast or a cup of peas at the end.

Storage

Store the sauce on its own in the fridge for up to 3 days. Rewarm it gently over low heat with a tablespoon of water; if it boils, the proteins tighten and the sauce can separate.
