Ingredients for america's test kitchen cheese and tomato lasagna

Precision-crafted ingredients for lasagna with restaurant-quality texture and flavor in every layer.

The foundation begins with San Marzano tomatoes—their sweetness and acidity balance perfectly for lasagna sauce. Purchase whole cans from specialty grocers like Whole Foods or Eataly for optimal quality. The ricotta should be 22% fat minimum—check labels at Trader Joe's or Costco for reliable options. For the mozzarella, low-moisture block cheese prevents excess moisture in layers. Shred it yourself using a box grater for consistent texture. The no-boil lasagna noodles must be standard width—check the packaging for 'oven-ready' labeling.

No ricotta? Cottage cheese blended smooth works in a pinch, though texture differs slightly. Substitute Pecorino Romano for Parmesan if unavailable, but reduce to 1 cup due to its sharper flavor. For the tomatoes, high-quality jarred marinara (like Rao's) can replace crushed tomatoes, though fresh is superior. The butter topping can be swapped for olive oil if preferred—simply brush lightly before baking. Fresh basil is ideal, but dried basil at one-third the amount suffices when fresh isn't available. Always use Diamond Crystal kosher salt—it dissolves more cleanly than table salt.

Store unassembled components separately in airtight containers for up to 3 days before baking. The assembled lasagna keeps 4 days refrigerated, though flavor peaks after 24 hours as flavors meld. For freezing, wrap tightly in foil and bake from frozen at 375°F for 60 minutes. Reheat portions in the oven to maintain texture integrity. Portion into individual servings before freezing for easy meal prep—simply reheat covered at 350°F for 20 minutes.

Step-by-step instructions for america's Test Kitchen cheese and tomato lasagna

Mastering this lasagna comes down to precise layering and timing—here's how to execute it flawlessly.

In a large saucepan, combine the 28 oz canned San Marzano tomatoes, 1 tsp dried oregano, 2 tsp diamond crystal kosher salt, and 0.5 tsp ground black pepper. Bring to a simmer over medium heat and cook uncovered for 20-25 minutes until reduced by about one-third and thickened. The sauce should coat the back of a spoon—this concentration is critical for flavor development.

Meanwhile, in a medium bowl, mix the 1.5 lbs ricotta cheese with 0.5 cup heavy cream, 1.5 cups freshly grated parmesan cheese, 0.25 cup chopped fresh basil leaves, and 0.5 tsp ground black pepper. Use your hands to gently fold until just combined—overmixing introduces air and creates a grainy texture. This mixture should be smooth but still slightly thick; if it's too loose, add 1-2 tablespoons of the reserved tomato sauce to bind it.

Heat the 0.25 cup extra-virgin olive oil in a large skillet over medium heat. Add the 1 whole yellow onion, finely diced, and cook for 5-6 minutes until softened and translucent. Add the 6 cloves minced garlic and cook for an additional 30 seconds until fragrant but not browned—burnt garlic adds bitterness that overpowers the delicate tomato sauce.

In a 9x13-inch baking dish, spread 1 cup of the reduced tomato sauce on the bottom. Arrange 4 sheets of no-boil lasagna noodles side by side, slightly overlapping if needed. Spread half of the ricotta mixture evenly over the noodles, then sprinkle 1/3 of the 2 lbs shredded mozzarella cheese on top. This layering order ensures the noodles absorb moisture without becoming soggy.

Spread another 1 cup of tomato sauce over the first layer, followed by 4 more sheets of no-boil lasagna noodles. Repeat the process with the remaining ricotta mixture and 1/3 of the mozzarella. For the final layer, add the last 1 cup of tomato sauce, the remaining 4 sheets of noodles, and the last 1/3 of mozzarella. Press down gently to ensure all layers adhere—this prevents shifting during baking.

Here's the thing—don't skip the final sprinkle of 1.5 cups parmesan cheese over the top. The parmesan acts as a protective crust, preventing the mozzarella from turning rubbery. Dot the surface with the 2 tbsp unsalted butter for extra richness and a golden finish. Cover the baking dish tightly with heavy-duty aluminum foil to prevent drying.

Preheat your oven to 375°F. Bake the lasagna for 40 minutes before removing the foil. This initial covered bake ensures the noodles soften and the cheese begins to melt without the top drying out. Return the lasagna to the oven, uncovered, and bake for an additional 15-20 minutes until the top is deep golden brown and the edges are bubbling.

Real talk: your oven might run hot, so start checking at the 15-minute mark. The lasagna is done when the cheese is bubbling vigorously and the edges are slightly crisp. Let it rest for 15 minutes before slicing—this allows the layers to set and makes for cleaner cuts. Serve with a side of garlic bread to soak up every last bit of that rich tomato sauce.

Flavor customization for this recipe

Spicy Kick

Transform this classic lasagna into a fiery Italian feast by adding 1-2 tablespoons of hot pepper flakes directly to your tomato sauce. For a smoother heat, blend 1-2 fresh jalapeños or ½ habanero (seeds removed) into the sauce before simmering.

I like adding ½ teaspoon of crushed red pepper to the ricotta mixture for a subtle, creamy heat throughout each layer. 🌶️

Herb Infusion

Elevate the flavor profile by folding 1 tablespoon of fresh thyme leaves or 1 teaspoon of dried thyme into the tomato sauce for an earthy depth. For a brighter twist, stir 2 tablespoons of fresh parsley into the ricotta mixture alongside the basil.

I also recommend adding ½ teaspoon of fennel seeds to the sautéed onions for a subtle licorice note that pairs beautifully with the tomato and cheese.

Meat Additions

For a heartier lasagna, layer 1 pound of Italian sausage (sweet or spicy) between the noodle sheets. Brown the sausage in a skillet first, then drain excess fat before mixing into the tomato sauce.

Alternatively, add 1 cup of cooked ground beef or ½ cup of finely chopped pancetta to the sauce for extra richness. I prefer using sweet Italian sausage from Applegate for a milder flavor that doesn't overpower the dish.

Vegetable Boost

Incorporate seasonal vegetables like 1 cup of finely chopped zucchini or ½ cup of roasted eggplant into the ricotta mixture for added texture. For a heartier dish, spread 1 cup of sautéed mushrooms between layers.

I love adding 1 cup of spinach or kale to the ricotta mixture—just wilt it first by sautéing with garlic for 2 minutes before mixing. This adds a subtle earthiness that complements the tomato sauce perfectly.

Cheese Variations

Swap out some of the mozzarella for ½ cup of shredded fontina or ½ cup of smoked provolone for a richer, more complex flavor. For a tangy twist, add ½ cup of shredded pecorino romano to the ricotta mixture.

I also recommend topping the final layer with ¼ cup of shredded asiago before baking—it adds a nutty depth that enhances the overall flavor profile.

Protein Swaps

Make this lasagna vegetarian-friendly by replacing the ricotta with a blend of 1 lb of firm tofu (crumbled and pressed) mixed with ½ cup of nutritional yeast for a cheesy flavor. For a meatier option, use 1 cup of lentils (cooked and seasoned) in place of half the ricotta.

I've also had great success using 1 cup of chickpeas mashed into the ricotta mixture for added protein and creaminess.
