Ingredients

Ingredient Amount Notes
No-boil lasagna noodles 9-12 sheets White flour, not whole wheat
Ricotta cheese 2 cups Whole milk recommended
Shredded mozzarella cheese 2 cups Divided for layers and topping
Grated Parmesan cheese 1/2 cup Optional, but adds flavor
Egg 1 large Binds the ricotta filling
Marinara sauce 2 1/2 cups Choose no-chunk, smooth sauce
Olive oil 1 tbsp For greasing the pan
Salt 1/2 tsp To taste
Black pepper 1/4 tsp To taste
Dried Italian herbs (optional) 1/2 tsp Oregano or basil, for flavor

Equipment

  • 9×13-inch baking dish
  • Mixing bowls
  • Measuring cups and spoons
  • Rubber spatula or spoon
  • Aluminum foil
  • Sharp knife (for serving)
  • Whisk or fork

Instructions

  1. Preheat your oven to 375°F (190°C).

    While the oven heats, gather all your ingredients and equipment. Lightly grease your 9×13-inch baking dish with olive oil to prevent sticking.

  2. Prepare the ricotta filling.

    In a medium mixing bowl, combine the ricotta cheese, egg, salt, black pepper, and dried Italian herbs (if using). Mix until smooth and well blended.

    For an extra creamy texture, whisk vigorously or use a fork to break up any lumps in the ricotta.

  3. Assemble the lasagna layers.

    Spoon about 1/2 cup of marinara sauce into the bottom of the prepared baking dish and spread evenly. Place a single layer of no-boil lasagna noodles over the sauce—usually 3-4 noodles fit per layer, depending on your dish size.

  4. Add the first cheese layer.

    Spread one-third of the ricotta mixture over the noodles. Sprinkle with one-third of the shredded mozzarella and a bit of Parmesan if using.

    Spoon another 1/2 cup sauce over the cheese layer.

  5. Repeat the layers.

    Add another layer of noodles, then continue with ricotta, mozzarella, Parmesan, and sauce. Repeat for a total of three layers, finishing with a layer of noodles, the remaining sauce, and a final generous topping of mozzarella and Parmesan.

  6. Cover and bake.

    Tightly cover the baking dish with aluminum foil. Place in the preheated oven and bake for 25 minutes.

    Covering with foil helps trap moisture and ensures the noodles cook through without drying out.

  7. Uncover and finish baking.

    Remove the foil and bake for an additional 15-20 minutes, until the top is bubbly and golden brown.

  8. Cool and serve.

    Allow lasagna to cool for at least 10-15 minutes before slicing and serving. This makes it easier to cut and helps the layers set.

Tips & Variations

  • Smooth sauce is key: Avoid chunky tomato sauces or ones with seeds, skins, or pieces of vegetables for best colonoscopy prep results.
  • Skip the veggies: While classic vegetarian lasagna is loaded with spinach or zucchini, keep this version simple for easier digestion. Add-ins like peeled, canned mushrooms (well rinsed and diced) can be tolerated by some, but always follow your doctor’s advice.
  • Make it ahead: Assemble the lasagna a day in advance, cover, and store in the refrigerator. Bake just before serving.
  • Dairy-free option: If you’re avoiding dairy, try this Cheeseless Vegetarian Lasagna Recipe That Tastes Amazing for a completely dairy-free version.
  • Flavor boost: Add a pinch of nutmeg to the ricotta mixture for a subtle warmth.
  • Single-serve portions: Bake in ramekins or a smaller dish for individual meals—great for freezing and reheating.
