Ingredients

Main Ingredients:

  • 1 tsp oil (for sautéing)
  • 1/2 onion (chopped)
  • 4 cloves of garlic (chopped)
  • 1 cup mixed veggies (such as peppers, carrots, zucchini)
  • 1/4 cup red lentils (uncooked; quick-cooking red lentils or masoor dal work best)
  • 1 cup tomato puree (or thick tomato sauce like marinara)
  • 1 to 1.5 cups diced tomatoes
  • 2 tsp Italian seasoning (mix of 1 tsp basil, 1/2 tsp oregano, parsley; generous dash of thyme, sage, and rosemary)
  • 1/4 tsp each onion powder and garlic powder
  • 1/2 to 3/4 tsp salt (adjust to taste)
  • 2 cups water or vegetable broth (for a soupier texture, use 2.5 to 3 cups)
  • 5 oz lasagna sheets (broken into small pieces; no-boil recommended)
  • Dash of black and white pepper
  • Pepper flakes (to taste; I use about 1/3 tsp)
  • 1 tbsp nutritional yeast (adds a cheesy flavor)
  • 1 cup packed spinach (optional)
  • Vegan pesto, ricotta, or mozzarella (for serving)
  • Vegan butter or garlic bread (optional)
  • 1 tbsp tomato paste (optional, for richer flavor)
  • Lemon juice (for brightness)

Notes on Ingredients:

  • Fresh or frozen veggies can be used; just make sure to chop them evenly for quick cooking.
  • If you’re missing a herb or two, don’t stress! Just mix with what you have.
  • For the best taste, use high-quality canned tomatoes and vegetable broth.

Step-by-Step Instructions

  1. Sauté Aromatics: In your Instant Pot, heat 1 tsp of oil on sauté mode. Add the chopped onion, garlic, and a pinch of salt, cooking for about 2 minutes until they become fragrant.

  2. Add Vegetables: Toss in your mixed veggies and stir to combine, allowing them to soften for around another 2-3 minutes.

  3. Combine Main Ingredients: Next, add the red lentils, tomato puree, diced tomatoes, salt, Italian seasoning, onion powder, and garlic powder. Give everything a good mix.

  4. Incorporate Lasagna Sheets: Gently add the broken lasagna sheets ensuring they’re well mixed into the sauce; this prevents them from clumping together.

  5. Add Broth: Pour in your 2 cups of water or veggie broth, stirring slightly to combine.

  6. Pressure Cook: Close the lid securely and set the pressure to cook on manual high for 3 minutes. Allow pressure to naturally release for 10 minutes; then, carefully release any remaining pressure.

  7. Season to Taste: Open the lid and mix in black pepper, pepper flakes, and nutritional yeast. Taste and adjust with more salt or Italian herbs, if desired. Add in fresh spinach and allow it to wilt for a minute.

  8. Serve: Let your soup sit for a moment before serving with a dollop of vegan pesto, a sprinkle of vegan cheese, or a side of garlic bread.

Chef’s Tips:

  • Make sure to break the lasagna sheets into smaller pieces to avoid them sticking together.
  • Add a splash of lemon juice to brighten flavors just before serving!

Expert Tips & Tricks

  • Storage: This soup can be stored in an airtight container in the fridge for up to 4 days or frozen for 3 months. Just reheat on the stovetop or microwave for a quick meal.

  • Make-Ahead: You can chop your veggies and mix the dry ingredients ahead of time, making it even quicker to throw together.

  • Troubleshooting: If your lasagna soup seems too thick, simply add more broth or water while reheating.

  • Flavor Enhancements: Try adding a dash of balsamic vinegar or a touch of soy sauce for an umami boost.

  • Meal Prep: Portion out in containers for easy grab-and-go lunches throughout the week!


Serving Suggestions
