“Blend the curds smooth, then protect the sauce with pasta water.”
A creamy baked pasta usually means making a roux or opening cream, and both push the dish somewhere heavy. Blended cottage cheese gets you the same coating with more protein and a fraction of the fat. The trade is that it needs a blender and a cup of starchy water, not a whisk and patience at the stove.
Two things break it. Curds that survive the blender stay grainy no matter how long it bakes, so run the machine until the mixture pours like thin paint. And the tomato base has to come off the burner before the cheese goes in; direct heat splits it into watery specks that never come back together.
🧀 The promise: a creamy baked pasta with no roux and no cream in it, built on a blender and a cup of starchy water.


Blending turns curds and whey into one sauce, and the starchy pasta water is what keeps that sauce bound to the tomato instead of splitting.
A ten-minute rest lets a deliberately loose sauce soak into pasta that came out of the pot two minutes early.
Heat the oven to 400°F (205°C). Boil the rigatoni in well-salted water for 2 minutes less than the package says, so the tubes still snap at the center, then dip out 1 cup (240 ml) of the starchy water before draining.

Warm the olive oil in a wide pot and cook the minced garlic 30 seconds, just to the point where it smells sweet. Stir in the tomato paste for 1 minute until it turns brick dark, then add the crushed tomatoes, oregano, and half the salt and simmer 8 minutes.

Blend the cottage cheese with the Parmesan, the remaining salt, and ½ cup (120 ml) of the reserved pasta water until it is completely smooth and pourable, with no curds left. Stop and scrape the jug once so nothing escapes the blade.

Pull the tomato sauce off the heat and stir the blended cheese through until the color evens to a pale coral. Fold in the drained pasta and the baby spinach, adding more pasta water until the sauce looks slightly looser than you want it.

Tip everything into a 9-by-13-inch dish and spread it level without pressing down, so the tubes keep air between them. Scatter the shredded mozzarella evenly across the top, right out to the corners where it browns first.

Bake 18–22 minutes, until the surface bubbles across the middle and the center reads 165°F (74°C). Rest the dish 10 minutes so the sauce sets enough to scoop, then tear the basil leaves over the top.

The sauce coats every tube without breaking into curds, the spinach has wilted through, and a serving lifts out cleanly after resting. If the mozzarella browns before the middle is hot, lay foil over the dish and keep baking until the center reads 165°F (74°C).
Cook the tomato paste until it darkens against the pan before the tomatoes go in, since that caramelized base is what balances the mild tang of the curds.
