Cheese Lasagna with Tomato Sauce

Introduction

Whipped egg whites folded into ricotta, mozzarella, or cheddar give this cheese lasagna a lighter filling than the usual dense layered version. With cooked lasagne noodles, 1 ½ cups of tomato sauce, and a 35-minute bake, it works for a weeknight dinner and reheats cleanly for lunch.

Recipe Details

• Prep Time: 20 minutes
• Cook Time: 35 minutes
• Total Time: 55 minutes
• Servings: 6

Ingredients

• 6 eggs, separated
• 2 cups ricotta cheese OR shredded mozzarella cheese OR shredded cheddar cheese
• 1 pinch of salt
• ¼ tsp freshly-ground white pepper
• ½ cup heavy cream
• ~1000 g cooked lasagne noodles
• 1 ½ cups Italian Tomato Sauce

Instructions

1. In a large spotlessly clean stainless steel bowl, whip egg whites to stiff peaks and set aside.
2. Combine egg yolks, cheese, salt, pepper, and heavy cream.
3. Gently fold egg whites into cheese mixture.
4. Lay half the cooked noodles in the bottom of a roasting pan. Add a layer of tomato sauce on top, then a layer of the cheese mixture. Repeat this step for a second layer of noodles/tomato/cheese. The last layer should be cheese.
5. Cover with aluminum foil and bake at 375°F for 15 minutes. Remove foil and bake for another 20 minutes.
6. Remove from oven, and let rest for 10 minutes. Serve.

Variations

• Use ricotta cheese for a softer, more custardy filling that spreads easily between the noodles.
• Use shredded mozzarella cheese for a stretchier texture and a milder flavor.
• Use shredded cheddar cheese for a sharper flavor and a firmer, more structured slice.
• Swap the Italian Tomato Sauce for a spicy arrabbiata or a basil-heavy marinara to change the heat level and herb profile without changing the method.
• Fold in squeezed-dry chopped spinach with the cheese mixture if you want more bulk and vegetable content; the filling will be slightly denser.

Tips for Success

• Keep the stainless steel bowl spotlessly clean before whipping the egg whites; any grease can keep them from reaching stiff peaks.
• Stop whipping when the egg whites hold firm points; if they look dry or clumpy, they are harder to fold in smoothly.
• Fold the egg whites into the cheese mixture with broad, gentle strokes so you keep as much air as possible.
• Drain the cooked lasagne noodles well before layering so excess water does not thin the tomato sauce.
• Let the lasagna rest the full 10 minutes after baking so the cheese layer sets and slices more cleanly.

Storage and Reheating

Store leftovers in an airtight container in the fridge for up to 4 days. For longer storage, wrap portions tightly and place them in a freezer-safe container for up to 2 months.

Reheat refrigerated portions in a 350°F oven, covered, for 15 to 20 minutes, or microwave individual pieces in 60-second bursts until heated through. Reheat from frozen after thawing overnight in the fridge for the most even texture.

FAQ

Which cheese works best in this recipe?

Ricotta gives you the softest, most traditional filling, mozzarella gives you more stretch, and cheddar makes the flavor sharper and the texture firmer.

Can you assemble it ahead of time?

You can assemble it a few hours ahead and refrigerate it covered. Because the filling relies on whipped egg whites, bake it the same day for the lightest texture.

Can you use oven-ready noodles instead of cooked lasagne noodles?

Not without adjustments. With only 1 ½ cups of sauce, oven-ready noodles may stay too firm unless you add more liquid.

Can you replace the heavy cream?

You can use half-and-half or whole milk if needed. The filling will be less rich and slightly looser after baking.
