Ingredients

  • 12 lasagna noodles (regular or no-boil)
  • 2 tablespoons olive oil
  • 1 medium onion, finely chopped
  • 4 cloves garlic, minced
  • 1 red bell pepper, diced
  • 1 zucchini, diced
  • 1 cup mushrooms, sliced
  • 1 can (28 oz) crushed tomatoes
  • 1 can (6 oz) tomato paste
  • 1 teaspoon crushed red pepper flakes (adjust to taste)
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • Salt and freshly ground black pepper, to taste
  • 15 oz ricotta cheese
  • 2 cups shredded mozzarella cheese
  • 1 cup grated Parmesan cheese
  • 1/4 cup chopped fresh parsley
  • 1 small jalapeño, finely chopped (optional for extra heat)

Equipment

  • Large pot for boiling noodles
  • Large skillet or sauté pan
  • 9×13 inch baking dish
  • Mixing bowls
  • Wooden spoon or spatula
  • Cheese grater
  • Aluminum foil
  • Measuring cups and spoons

Instructions

  1. Preheat your oven to 375°F (190°C). If using regular lasagna noodles, bring a large pot of salted water to a boil and cook noodles according to package instructions until al dente. Drain and lay them flat to prevent sticking.
  2. Prepare the spicy tomato sauce. Heat olive oil in a large skillet over medium heat. Add chopped onion and sauté for 3-4 minutes until translucent. Stir in minced garlic, diced red bell pepper, zucchini, mushrooms, and jalapeño if using. Cook for another 5-6 minutes until vegetables soften.
  3. Add crushed tomatoes, tomato paste, and spices. Stir in crushed red pepper flakes, smoked paprika, oregano, basil, salt, and pepper. Reduce heat to low and simmer the sauce for 15-20 minutes, stirring occasionally. This allows the flavors to meld beautifully.
  4. Mix the ricotta cheese layer. In a medium bowl, combine ricotta cheese with half of the chopped parsley and a pinch of salt and pepper. This will add freshness and creaminess to your layers.
  5. Assemble the lasagna. Spread a thin layer of sauce on the bottom of your baking dish to prevent sticking. Lay down 3-4 noodles over the sauce. Spread a third of the ricotta mixture over the noodles, then spoon a third of the tomato-vegetable sauce on top. Sprinkle a layer of mozzarella and Parmesan cheese.
  6. Repeat the layering process twice more. Noodles, ricotta, sauce, and cheese until you’ve used all your ingredients. Finish with a generous layer of mozzarella and Parmesan on top.
  7. Cover with aluminum foil and bake. Bake the lasagna covered for 30 minutes. Then, remove the foil and bake for an additional 10-15 minutes until bubbly and golden brown on top.
  8. Let it rest. Once out of the oven, allow the lasagna to sit for 10-15 minutes before slicing. This helps the layers set and makes serving easier.

Tips & Variations

For a gluten-free version, swap the regular lasagna noodles with gluten-free noodles or thinly sliced zucchini strips.

If you prefer a creamier texture, try adding a béchamel sauce layer or mixing ricotta with some shredded mozzarella.

Want it extra spicy? Add more crushed red pepper flakes or include a splash of hot sauce in your tomato sauce.

For added protein, toss in some cooked lentils or crumbled tofu into the tomato sauce.
