Equipment
- High-speed blender or food processor For blending cottage cheese completely smooth
- Large pot For boiling pasta
- Wide skillet or sauté pan 12-inch recommended
- Wooden spoon or silicone spatula
- Colander For draining pasta
- Box grater or microplane For freshly grating parmesan
- Ladle or liquid measuring cup For reserving pasta water
Ingredients
For the Sauce
- 1 ½ cups full-fat cottage cheese about 340g; 4% milk fat recommended for best creaminess
- ½ cup whole milk 120ml; or milk of choice
- ¾ cup Parmigiano Reggiano about 75g, freshly grated and divided; use ½ cup in blender, ¼ cup stirred in at end
- 1 ½ tablespoons unsalted butter about 21g
- 4 cloves garlic minced
- 1 teaspoon cornstarch helps stabilize and thicken the sauce
- ½ teaspoon garlic powder
- ½ teaspoon Italian seasoning
- ¼ teaspoon black pepper freshly cracked; plus more to taste
- salt to taste
For the Pasta
- 12 oz fettuccine about 340g; or pasta shape of choice
- 1 cup reserved pasta water scooped out before draining; use as needed to adjust sauce consistency
For Garnish
- fresh parsley chopped, for serving
- Parmigiano Reggiano extra freshly grated, for serving
- red pepper flakes optional, for a touch of heat
Instructions
- Bring a large pot of generously salted water to a full rolling boil over high heat. Cook the fettuccine until al dente according to package directions, then scoop out 1 cup of pasta water before draining.
- Add the cottage cheese, milk, ½ cup of the Parmigiano Reggiano, garlic powder, Italian seasoning, and black pepper to a high-speed blender. Blend on high for 60–90 seconds until completely smooth with no visible curds remaining.
- Melt the butter in a wide skillet over LOW heat, then add the minced garlic and sauté for 2–3 minutes, stirring frequently, until fragrant and pale golden. Do not let it brown.
- Pour the blended cottage cheese mixture into the skillet with the garlic over low heat, whisk in the cornstarch, and stir continuously for 3–4 minutes until the sauce is warm and slightly thickened. Stir in the remaining ¼ cup of Parmigiano Reggiano until fully melted.
- Add the drained pasta to the skillet and toss to coat, adding splashes of reserved pasta water as needed to reach a silky, flowing consistency. Taste and adjust seasoning, then serve immediately topped with extra parmesan, fresh parsley, and black pepper.
Notes
- Blend thoroughly: Blend for a full 60–90 seconds and check that zero curds remain before adding to the pan — this step determines whether your sauce is silky or grainy.
- Keep heat LOW: High heat causes the proteins in cottage cheese to seize and curdle. Use the lowest heat setting throughout cooking and never let the sauce boil.
- Use full-fat cottage cheese: 4% milk fat cottage cheese yields the richest, creamiest sauce. Low-fat works but produces a slightly thinner result.
- Always freshly grate your parmesan: Pre-grated parmesan contains anti-caking agents that make the sauce grainy. Grate from a block for the best melt and flavor.
- Don't skip the pasta water: Starchy pasta cooking water adjusts sauce consistency without diluting flavor — add it a splash at a time until perfectly creamy.
- Make ahead: The blended cottage cheese mixture can be stored in an airtight jar in the refrigerator for up to 2 days. Warm gently in the skillet when ready to use, adding a splash of milk to loosen.
- Storage: Store leftover pasta in an airtight container in the refrigerator for up to 4 days. Reheat gently in a skillet over low heat with a splash of milk, or microwave in 30-second intervals, stirring between each. Freezing is not recommended as the sauce can separate.
- Protein add-ins: Toss in grilled chicken, sautéed shrimp, flaked salmon, or crispy tofu to turn this into a complete, protein-packed entrée.
- Flavor variations: Add 1–2 tsp Cajun seasoning for a spicy kick, fresh lemon zest for brightness, or wilted baby spinach for a vegetable-loaded version.
- Pasta shape tips: Fettuccine, linguine, penne, and rigatoni all work beautifully — choose a shape with ridges or width to help the creamy sauce cling.
