Cottage Cheese Lasagna Recipe with Rich Tomato Sauce

This cottage cheese lasagna layers tender pasta with a savory beef-and-tomato sauce and a creamy, seasoned cheese filling. It is a practical, comforting baked pasta with familiar Italian-American flavors; cottage cheese makes the filling pleasantly soft, and a short rest after baking helps the slices hold together.

Ingredients

1 tablespoon (15 ml) olive oil
1 medium yellow onion, finely chopped, about 1 cup (150 g)
3 garlic cloves, minced, about 1 tablespoon (9 g)
1 pound (450 g) lean ground beef
1 can crushed tomatoes, 28 ounces (794 g)
1 can tomato sauce, 15 ounces (425 g)
2 tablespoons (30 g) tomato paste
1/2 cup (120 ml) water
2 teaspoons (4 g) dried Italian seasoning
1 teaspoon (6 g) fine salt, plus more for the cheese mixture if needed
1/2 teaspoon (1 g) black pepper
1/4 teaspoon (0.5 g) red pepper flakes, optional
2 cups (450 g) small-curd cottage cheese
1 large egg, about 50 g
1/2 cup (45 g) finely grated Parmesan cheese
2 tablespoons (8 g) chopped fresh parsley, plus extra for serving
9 oven-ready lasagna noodles, about 8 ounces (225 g), or enough to make three layers
3 cups (340 g) shredded low-moisture mozzarella cheese

Instructions

Heat the oven and prepare the pan. Set a rack in the center and heat the oven to 375°F (190°C). Lightly oil a 9-by-13-inch (23-by-33-cm) baking dish. Set out the ingredients so the sauce and filling can be assembled without a long pause.
Brown the beef. Warm the olive oil in a large, heavy saucepan or deep skillet over medium heat. Add the onion and cook for 4 to 5 minutes, stirring, until softened. Stir in the garlic for about 30 seconds, then add the ground beef. Break it into small pieces and cook for 6 to 8 minutes, until no pink remains. Check the thickest pieces with a food thermometer: ground beef must reach the USDA FSIS safe minimum internal temperature of 160°F (71°C).
Make the tomato sauce. Stir in the crushed tomatoes, tomato sauce, tomato paste, water, Italian seasoning, salt, black pepper, and red pepper flakes, if using. Bring the mixture to a gentle simmer, then reduce the heat and cook uncovered for 15 minutes, stirring occasionally. The sauce should be loose rather than thick; oven-ready noodles need moisture as they bake. Taste and adjust the salt or pepper. Turn off the heat.
Mix the cheese filling. In a medium bowl, stir together the cottage cheese, egg, Parmesan, and parsley until evenly combined. The mixture may look slightly lumpy because of the cottage cheese curds; that is normal. If your cottage cheese is very watery, drain it in a fine-mesh strainer for a few minutes first so the lasagna is less likely to turn soupy.
Build the layers. Spread about 1 cup (240 ml) of meat sauce across the bottom of the baking dish. Arrange three oven-ready noodles over it, leaving a little space around the edges because they expand as they hydrate. Spread about one-third of the cottage cheese mixture over the noodles, add roughly 1 cup (240 ml) of sauce, then sprinkle with 1 cup (113 g) mozzarella. Repeat this sequence twice, finishing with sauce and the remaining mozzarella. Distribute sauce close to the corners and edges so exposed noodle tips do not dry out.
Bake covered, then uncovered. Cover the dish tightly with foil, tenting it slightly so the foil does not press into the cheese. Bake for 30 minutes. Remove the foil and bake for another 15 minutes, until the sauce bubbles around the edges and the cheese is melted and lightly browned. Check the center with a food thermometer; because this filling contains egg, the egg dish should reach 160°F (71°C), the USDA FSIS safe minimum temperature.
Rest before slicing. Set the lasagna on a heat-safe surface and let it stand for 20 minutes. This resting time lets the sauce settle and the layers firm up, making neater portions. Sprinkle with extra parsley if desired, cut into eight servings, and serve hot.

Tips

Keep the sauce moist enough. Oven-ready noodles absorb liquid from the sauce, so do not reduce it until very thick. If your sauce simmers down more than expected, stir in a little water before assembling. Make sure every noodle is covered with sauce, especially around the perimeter.
Choose cottage cheese to suit the texture. Small-curd cottage cheese spreads readily and leaves a classic, softly textured filling. Large-curd cottage cheese works too; pulse it briefly in a food processor if you want a smoother layer. Low-fat cottage cheese can be substituted, though its filling may be a little less rich and can release more water.
Let it rest, and use a sharp knife. Cutting immediately after baking can make the layers slide apart. A full 20-minute rest improves the shape of each piece. Wipe the knife between cuts if you want especially tidy portions.
Make it ahead without baking. Assemble the dish, cover it tightly, and refrigerate it for up to 24 hours before baking. Since the noodles will have time to absorb sauce, check that the top is still moist; add a few spoonfuls of water or sauce if it looks dry. Bake it straight from the refrigerator and allow extra time, checking the center for 160°F (71°C).

Serving Suggestions

Serve each portion with a crisp green salad dressed with a simple vinaigrette to balance the rich cheese and tomato sauce. Garlic bread, toasted Italian bread, or warm focaccia is useful for catching extra sauce. For a more substantial meal, add roasted broccoli, green beans, or zucchini; keep the vegetable seasoning simple so it complements rather than competes with the lasagna.

For a casual dinner, let the lasagna rest while you dress the salad and warm the bread. Cut it into eight generous squares with a broad spatula, and offer extra Parmesan, black pepper, or chopped parsley at the table. The dish is filling, so smaller portions alongside several sides can also work well for a larger gathering.

Variations

Make it meatless: Leave out the beef and sauté 8 ounces (225 g) chopped mushrooms with the onion until their moisture cooks off. Add the tomato ingredients as written. You can also use 10 ounces (280 g) thawed, well-drained chopped spinach in the filling, but squeeze it very dry first to avoid adding excess water.

Use Italian sausage: Replace the ground beef with 1 pound (450 g) bulk Italian sausage. Brown it thoroughly and check that ground meat reaches 160°F (71°C). Sausage is often saltier and more seasoned, so taste the sauce before adding the full teaspoon of salt.

Add herbs or greens: Replace the dried Italian seasoning with 1 teaspoon (1 g) dried oregano and 1 teaspoon (1 g) dried basil, or add 1/2 cup (12 g) chopped fresh basil to the sauce after simmering. For spinach, use frozen chopped spinach that has been thawed and squeezed dry, or briefly wilt fresh spinach and cool it before mixing it into the cottage cheese.

Swap the pasta or cheese: Regular lasagna noodles can replace oven-ready sheets, but boil them according to the package directions until just flexible, drain, and pat dry before layering. A blend of mozzarella and provolone can replace some or all of the mozzarella for a sharper, more savory flavor. Keep the total amount of shredded cheese close to 3 cups (340 g) so the top melts without becoming overly heavy.

Storage and Reheating

Refrigerate cooked lasagna within 2 hours of baking. Store cooled portions in an airtight container, or cover the baking dish tightly, and keep them refrigerated for 3 to 4 days. For easier weekday meals, cut the cooled lasagna into individual portions before storing; this also makes it simpler to reheat only what you need.

To reheat a portion in the microwave, place it in a microwave-safe dish, cover loosely, and heat in short intervals until steaming throughout, checking that the center reaches 165°F (74°C). For a larger amount, cover the dish with foil and warm it in a 350°F (175°C) oven until hot in the middle; uncover briefly at the end if you want the cheese to crisp again. Leftovers should reach 165°F (74°C) when reheated.

Lasagna can also be frozen for up to 3 months for best quality. Freeze individual portions in airtight, freezer-safe containers, or freeze the assembled unbaked dish tightly wrapped. Thaw frozen cooked portions in the refrigerator before reheating, or bake a frozen unbaked lasagna covered until hot through, allowing considerably more time than for a chilled dish and checking the center with a thermometer. Do not leave it at room temperature to thaw.

Frequently Asked Questions

Can I use regular cottage cheese instead of small-curd?
Yes. Any curd size works. Large curds give the filling a more noticeable texture; for a smoother, ricotta-like consistency, briefly pulse the cottage cheese in a food processor. If it has a pool of liquid, drain it first.

Does cottage cheese make lasagna watery?
It can if the cheese is unusually wet, the sauce is too thin, or the noodles are not covered evenly. Drain watery cottage cheese, simmer the sauce until it is loose but not watery, and spread sauce all the way to the edges. Resting the baked dish for 20 minutes also helps the layers set.

Can I make this without the egg?
Yes. The egg helps the cheese layer hold together, but it is not essential. Leave it out and mix the cottage cheese with the Parmesan and parsley as directed. The filling may be softer, so take care when spreading it and allow the full resting time before slicing.

Can I assemble cottage cheese lasagna the day before?
Yes. Cover the assembled, unbaked dish and refrigerate it for up to 24 hours. The noodles will absorb some sauce while it sits, so keep the sauce moist and check the top before baking. Bake until bubbling and verify that the center reaches 160°F (71°C).

Why did my lasagna fall apart when I cut it?
The most common reason is slicing too soon. Let it rest for 20 minutes after baking so the sauce and filling can settle. A very loose sauce or overly wet cottage cheese can also make slices slump, so drain the cheese when needed and avoid adding extra liquid beyond the recipe amount.

Can I freeze the leftovers?
Yes. Cool and portion the lasagna, then freeze it in airtight containers for up to 3 months for best quality. Thaw portions in the refrigerator and reheat until the center reaches 165°F (74°C). Freezing may soften the noodles slightly, but the flavor and layered structure remain suitable for a convenient meal.
