Best Vegetarian Lasagna (Print Version)

# Ingredients:

→ Vegetables

01 - 1 medium zucchini, sliced into ½-inch pieces
02 - 3 cups baby spinach, fresh
03 - 8 ounces of cremini mushrooms, stems removed and cut into quarters
04 - ½ a medium yellow onion, diced into ½-inch chunks
05 - 1 large red bell pepper, chopped into 1-inch squares

→ Ricotta Filling

06 - 24 ounces (or 3 cups) of full-fat ricotta cheese
07 - Grated zest of 1 lemon (roughly 2 teaspoons)
08 - 3 minced garlic cloves
09 - A teaspoon of fine sea salt
10 - Some freshly cracked black pepper, as you like

→ Assembly

11 - 3 cups marinara sauce (24 ounces)
12 - 15 sheets of lasagna pasta
13 - Half a cup of grated pecorino romano cheese
14 - 2 cups of shredded mozzarella (part-skim) cheese
15 - Drizzle of extra virgin olive oil
16 - Fresh chopped parsley or whole basil leaves for topping

# Instructions:

01 - Set your oven to 425°F. Coat a 9x13 pan with olive oil and line a baking sheet with parchment.
02 - Spread veggies out on the baking sheet, toss them with salt, pepper, and oil. Roast 20-25 minutes till golden brown. Turn oven down to 400°F.
03 - Boil lasagna sheets till they’re al dente. Drain, then toss them with oil to stop sticking.
04 - In a big mixing bowl, combine ricotta, lemon zest, garlic, salt, and pepper.
05 - Start layering: sauce first, noodles next, then ricotta, spinach, and veggies. Keep repeating. Finish with sauce, noodles, and the cheeses.
06 - Bake at 400°F for half an hour, till the cheese bubbles and gets golden. Let it cool 20 minutes before serving.

# Notes:

01 - Make it vegan by swapping out cheese and ricotta for plant-based versions
02 - No-boil pasta works too, but adjust cooking time
03 - For the richest texture, stick with regular lasagna pasta
