The classic Ronzoni lasagna recipe features a hearty homemade meat sauce, a simple but essential creamy ricotta mixture with egg, and layers of tender pasta. Known as the classic “recipe on box,” it’s beloved for its reliability and family-style comfort. The magic comes from properly layering sauce, noodles, and cheese for the perfect classic baked lasagna every time.
Every Italian-American family I know has a story about learning to make lasagna straight from that familiar blue Ronzoni box. For many of us, this was the first “big” dish we ever tackled—a Sunday supper right of passage. There’s something wonderfully comforting about the ronzoni lasagna recipe, especially the way it’s been faithfully passed from kitchen to kitchen, handwritten onto recipe cards, and tucked into cookbooks.
Today, I’m sharing the definitive ronzoni lasagna recipe, built on the beloved “recipe on box” but enhanced with the tips and touches that home cooks learn after decades of making this classic baked lasagna. The structure is the same—meat sauce, ricotta mixture, layering—but with deeper flavor and a little more finesse. Let’s get cooking.
The Cornerstone: Mastering the Homemade Meat Sauce
While the original ronzoni lasagna recipe on box keeps things straightforward, a truly great lasagna begins with a well-balanced homemade meat sauce. You don’t need anything fancy—just a blend of ground beef (and optionally, a bit of sweet Italian sausage), tomatoes, and classic seasonings.
A slow simmer helps deepen the flavor, but even 20–30 minutes will give you a hearty, savory base that holds up beautifully between the pasta layers.
My pro tip: Add a splash of water to loosen the sauce slightly. Lasagna needs moisture to cook evenly and bind the layers.
The Heart of the Dish: Crafting the Perfect Creamy Ricotta Mixture
If the meat sauce gives lasagna body, the ricotta mixture gives it soul.
The secret to the creamy, slightly puffed middle layer is the egg—it binds everything together and keeps the ricotta from becoming grainy or watery. Mix in parsley, salt, pepper, and a whisper of Italian seasoning, and you’ve got a filling that tastes like home.
Extra tip: Add 2–3 tablespoons of grated Parmesan to the ricotta for a richer, more rounded flavor.
Assembly Secrets: Building the Layered Italian Casserole
Lasagna is all about structure—each layer supporting the next so the whole dish slices beautifully.
Start with sauce on the bottom (always!), then noodles, then ricotta, then mozzarella… and repeat.
To Boil or Not to Boil? The No-Boil Noodles Hack
The Ronzoni box instructions call for traditional boiled noodles, and there’s nothing wrong with that. But many home cooks now use a no-boil noodles hack: soak the noodles briefly in hot water for 5–10 minutes before layering.
This softens them just enough to cook perfectly in the oven while absorbing flavor from the sauce, just like homemade sheets.

Ingredients
| Component | Ingredients |
| Meat Sauce | 1 lb ground beef (or ½ lb beef + ½ lb Italian sausage), 1 medium onion (diced), 2 cloves garlic (minced), 1 can (28 oz) crushed tomatoes, 1 can (15 oz) tomato sauce, 1 tsp salt, ½ tsp pepper, 1 tsp Italian seasoning, 1 tbsp olive oil |

| Pasta & Cheese | 12 Ronzoni lasagna noodles (boiled or soaked), 3 cups shredded mozzarella, ¼ cup grated Parmesan |
| Optional Enhancers | Pinch of red pepper flakes, 1 tsp sugar (for acidity), fresh basil |
Instructions / Layering Steps
| Step | Instruction |
| 1 | Make the Meat Sauce: Sauté onions in olive oil until soft. Add garlic, then brown the meat. Stir in crushed tomatoes, tomato sauce, salt, pepper, and Italian seasoning. Simmer 20–30 minutes. |
| 2 | Prepare Ricotta Mixture: Combine ricotta, egg, Parmesan, parsley, salt, and pepper until smooth. |
| 3 | Prepare Noodles: Boil until tender OR soak no-boil noodles in hot water for 5–10 minutes. |
| 4 | Start Layering: Spread 1 cup of meat sauce in the bottom of a 9×13″ baking dish. |
| 5 | Add the first layer of noodles, slightly overlapping. |
| 6 | Spread ⅓ of the ricotta mixture over the noodles, top with meat sauce, then sprinkle mozzarella. |
| 7 | Repeat for 2 more layers: noodles → ricotta → sauce → mozzarella. |
| 8 | Finish with noodles, sauce, and a final blanket of mozzarella + Parmesan. |
| 9 | Cover with foil (tenting it so it doesn’t touch the cheese). Bake at 375°F for 25 minutes. |
| 10 | Remove foil and bake 20–25 minutes more until bubbling and golden. |
| 11 | Rest 10–15 minutes before slicing so the lasagna sets properly. |
