Zucchini penne with lemon, cottage cheese & nuts
Cottage cheese in a pasta sauce sounds wrong until you stir it into hot penne and watch it happen. The curds soften, the lemon loosens everything, and in about thirty seconds you have a creamy sauce that wraps around every tube of penne without a drop of heavy cream.
The whole thing comes together in 20 minutes with 7 ingredients. Sautéed zucchini rounds go golden in olive oil, garlic gets one minute to bloom, and the nuts go in last for crunch. One bowl, 33g of protein and 767 kcal, and most of the work happens while the pasta boils.
Ingredients
- penne, whole wheat 3 ounces
- zucchini 1
- garlic 1 clove
- mixed nuts, unsalted 1 ounce
- olive oil 1 tablespoon
- cottage cheese, 4% milkfat 4 ounces
- lemon juice 1 squeeze
Method
-
Cook the pasta according to the package instructions.
-
Slice the zucchini into thin rounds or ribbons, finely chop the garlic, and roughly chop the nuts.
-
Heat the oil in a frying pan over medium heat and sauté the garlic for 1 minute until fragrant.
-
Add the zucchini and cook for 4–5 minutes, until lightly golden and tender. Season with salt and pepper.
-
Add the pasta, cottage cheese, and lemon juice to the pan. Stir well until the cottage cheese melts and forms a creamy sauce.
-
Stir in the nuts. Serve the pasta in a deep bowl.
Pull the pan off direct heat or drop it to low before the cottage cheese goes in. The pasta and zucchini are already hot enough to melt the curds into a smooth sauce. Too much direct flame separates the moisture out and leaves you with a thin, watery coating instead of a creamy one.
Behind this recipe
Why does cottage cheese work as a pasta sauce?
Cottage cheese is primarily casein protein, which holds its structure when heated — unlike whey, which tends to separate and curdle. When you stir it into hot pasta, the casein redistributes into a smooth, creamy coating rather than breaking down. The lemon juice helps tighten the texture further. For the best results, add the cottage cheese after lowering the heat — residual warmth from the pasta and zucchini is enough to do the work.
Can I use regular pasta instead of whole wheat?
Yes. White penne handles the cottage cheese sauce just as well. The swap costs you fiber — whole wheat is where most of the recipe's 11g comes from. Protein and calorie counts stay close, but the fiber drops significantly.
What nuts work best in this recipe?
The recipe uses mixed unsalted nuts for variety in flavor and texture. Walnuts or almonds work well on their own. Toasting them in a dry pan for 2–3 minutes before adding them brings out more flavor and adds a crunchier contrast against the creamy sauce.
