1-Step One: Prepare Your Workspace and OvenStart by preheating your oven to 375°F. This temperature allows the lasagna to cook evenly without drying out. While the oven heats, gather all your ingredients and tools. You’ll need a medium saucepan for the meat sauce, a mixing bowl for the ricotta mixture, and a 9×13-inch baking dish. Having everything ready before you start makes the process smooth and enjoyable.

2-Step Two: Cook the Ground BeefIn a medium saucepan over medium-high heat, brown one pound of ground beef. Break it up with a wooden spoon as it cooks, continuing until the meat is no longer pink about 5 to 7 minutes. Drain any excess fat if needed, though keeping a little adds flavor. Cheese and beef together create a protein-rich dish, but as WebMD notes, moderation is key for a balanced approach.

3-Step Three: Add Aromatics and SeasoningsAdd one small diced onion to the browned beef, along with one tablespoon of dried oregano, half a teaspoon of salt, and half a teaspoon of pepper. Cook this mixture for about 5 minutes, stirring occasionally, until the onion becomes translucent and fragrant. The onion releases its natural sweetness, balancing the savory beef beautifully.

4-Step Four: Create the Meat SaucePour in the entire jar of marinara sauce (24 ounces) and add one cup of water. The extra liquid is crucial it helps cook the noodles and keeps the lasagna moist. Bring the mixture to a boil, then immediately remove from heat. This sauce will be slightly thinner than pasta sauce, but don’t worry it thickens perfectly during baking.

5-Step Five: Prepare the Ricotta MixtureIn a separate bowl, combine 15 ounces of ricotta cheese with two eggs, the remaining tablespoon of dried oregano, half a cup of grated Parmesan cheese, and additional salt and pepper to taste. Mix until completely smooth and creamy. The eggs are essential here they help the ricotta set properly during baking, so don’t skip them.

6-Step Six: Start Layering Your LasagnaNow comes the fun part building those beautiful layers! In your 9×13-inch baking dish, spread a thin layer of meat sauce across the bottom. This prevents the noodles from sticking and creates a flavorful foundation. Place three lasagna noodles on top, slightly overlapping if needed.

7-Step Seven: Add the Cheese LayerSpread about one-third of the ricotta mixture over the noodles, then sprinkle some of the mozzarella cheese on top. Don’t worry about making it perfect rustic is part of the charm. Repeat this layering process twice more: sauce, noodles, ricotta, mozzarella.

8-Step Eight: Finish the Top LayerFor the final layer, spread the remaining ricotta mixture and top with all the remaining mozzarella about two cups. This generous cheese topping creates that gorgeous golden crust everyone loves. Make sure the cheese covers the entire surface for even browning.

9-Step Nine: Bake CoveredCover the baking dish tightly with aluminum foil. This traps moisture and ensures the noodles cook properly. Bake at 375°F for one hour. The foil prevents the top cheese from over-browning while the interior cooks through.

10-Step Ten: Uncover and Finish BakingRemove the foil carefully there will be hot steam! Bake for an additional 15 minutes uncovered. This final baking time allows the top to become bubbly and golden brown. You’ll know it’s ready when the cheese is melted and slightly browned in spots.

11-Step Eleven: Rest Before SlicingThis is the hardest part waiting! Let your meat lasagna rest for 15 to 20 minutes before slicing. This resting period allows the layers to set, making clean, beautiful slices possible. If you cut too soon, the layers will slide apart. Patience pays off here.
