Almost-Vegan Lasagna

Ingredients

“Meaty” Tomato Sauce

2 tablespoons extra-virgin olive oil1 small onion, chopped fine½ green bell pepper, chopped fine1 cup coarsely chopped walnuts2 garlic cloves, minced1 tablespoon minced fresh parsley1½ teaspoons dried oregano1 teaspoon garlic powder1 teaspoon onion powder¼ teaspoon table salt¼ teaspoon pepper1 tablespoon tomato paste¼ cup dry red wine1 teaspoon vegetable broth base (optional)1 (24-ounce) jar marinara sauce

Avocado “Ricotta”

1 ripe avocado, halved, pitted, and cut into 1-inch pieces½ cup plain whole-milk Greek yogurt2 tablespoons chopped fresh parsley1 tablespoon lemon juice1 teaspoon onion powder1 teaspoon garlic powder¼ teaspoon table salt¼ teaspoon pepper

Bread Crumb Topping

½ cup panko bread crumbs2 tablespoons nutritional yeast2 tablespoons extra-virgin olive oil⅛ teaspoon table salt2 zucchini (10 to 12 ounces each), trimmed

Before You Begin

Use a good-quality marinara sauce such as the test kitchen’s favorite, Rao’s Homemade Marinara Sauce. If you have vegetable broth base on hand (we like Orrington Farms Vegan Chicken Flavored Broth Base and Seasoning), add a little to the tomato sauce. Slicing the zucchini 1/16 inch thick is important for the success of this dish; a mandoline makes easy work of this, but a vegetable peeler can also be used. Use coconut or almond milk yogurt to make this dish vegan.

Instructions

    tomato sauce

  1. FOR THE “MEATY” Heat oil in Dutch oven over medium heat until shimmering. Add onion, pepper, and walnuts and cook until onions are translucent, 2 to 3 minutes. Stir in garlic, parsley, oregano, garlic powder, onion powder, salt, and pepper and cook until fragrant, about 1 minute. Stir in tomato paste; wine; and vegetable base, if using, and cook until wine is reduced by half, 1 to 2 minutes. Stir in marinara; bring to simmer; and cook until flavors meld, 6 to 8 minutes. Season with salt and pepper to taste.
  2. FOR THE AVOCADO “RICOTTA”: Pulse all ingredients in food processor until mixture is cohesive but not completely smooth, about 10 pulses, scraping down sides of bowl as needed.
  3. for the bread crumb topping

  4. Combine all ingredients in small bowl.
  5. Adjust oven racks to upper-middle and lower-middle positions and heat oven to 350 degrees. Using mandoline, slice zucchini lengthwise into 1/16-inch-thick noodles. Cut noodles in half crosswise. Grease four shallow 6-ounce gratin dishes. Spread ¼ cup tomato sauce in bottom of each dish. Shingle 4 zucchini noodles on top of sauce on slight diagonal. Shingle 4 more zucchini noodles over first layer on slight diagonal in opposite direction. Spread 2 tablespoons “ricotta” over noodles. Repeat layering in each dish as follows: ¼ cup sauce, 8 noodles, 2 tablespoons ricotta, and ¼ cup sauce. Sprinkle bread crumb mixture evenly over each dish.
  6. Place dishes on 2 rimmed baking sheets (2 dishes per sheet) and bake for 10 minutes. Remove sheets from oven and heat broiler. Place one sheet on lower rack and broil until crumbs are golden brown, 2 to 4 minutes. Repeat with second sheet. Serve.

Why This Recipe Works

This unexpected lasagna won the “creative substitution” challenge in episode 5 of America's Test Kitchen: The Next Generation. Contestants were asked to address diet-related substitutions in classic recipes—in this case, lasagna without meat or cheese. Antoinette knocked it out of the park with an avocado “ricotta” that nicely replicated the creamy texture of cheese. She amped up the “meaty” elements in her tomato sauce by adding walnuts, tomato paste, red wine, and vegetable broth base. Crispy crumbs flavored with nutritional yeast crowned this lasagna. And even though the challenge allowed Antoinette to use pasta, she decided to use thinly shaved zucchini instead. The end result was both light and satisfying.
