Instructions
 

  • Preheat the oven to 375ยฐF.
  • In a large skillet or Dutch oven, heat the olive oil over medium-high heat. Add the onion, bell pepper, mushrooms, and zucchini. Cook for 7โ€“8 minutes, stirring occasionally, until the vegetables are soft. Add the minced garlic and cook for another 30 seconds, stirring constantly.
  • Stir in the marinara sauce, Italian seasoning, salt, pepper, red pepper flakes, and parsley. Bring the sauce to a gentle simmer, then reduce the heat to low. Let it simmer for 10โ€“15 minutes, stirring occasionally. Stir in the chopped spinach during the last minute of cooking.
  • Meanwhile, in a medium bowl, lightly beat the egg with a fork. Add the ricotta cheese and mix until well combined. Shred the mozzarella cheese and set aside.
  • To assemble the lasagna, spread about 1 cup of the sauce on the bottom of a 9×13-inch baking dish. Lay 3 lasagna noodles on top. Spread โ…“ of the remaining sauce over the noodles, then add small spoonfuls of half the ricotta mixture. Sprinkle โ…“ of the mozzarella and โ…“ of the Parmesan cheese over the top.
  • Repeat with another layer of 3 noodles, half of the remaining sauce, the rest of the ricotta mixture, and half of the remaining mozzarella and Parmesan.
  • Finish with the final 3 noodles, the remaining sauce, and the rest of the mozzarella and Parmesan.
  • Cover the dish with foil sprayed with cooking spray (spray side down) to prevent the cheese from sticking.
  • Place the lasagna in the center of the oven. Put a rimmed baking sheet on the rack below to catch any drips. Bake covered for 35 minutes, then uncover and bake for 10โ€“15 minutes more, until hot and bubbling with lightly browned cheese on top.
  • Let the lasagna rest for 15 minutes before slicing and serving – this helps it set and prevents it from being too soupy.

Notes

Store leftover lasagna in the refrigerator for up to 3โ€“4 days after baking. You can also freeze it after baking for up to 3 months. To reheat, thaw first and then warm in the microwave or in a covered dish in the oven until heated through and steaming.
To make ahead: Assemble the lasagna, cover, and refrigerate for up to 24 hours before baking. If baking straight from the fridge, add about 15 minutes to the total bake time.
This recipe can also be halved and baked in a 9×9-inch dish.
