Ingredients
  

  • 4 clove garlic Mince finely to release pungent, aromatic flavor and add depth to the soup; sauté briefly in oil to bloom its essential oils and build the savory base.
  • 1/2 medium onion Chop small to provide mild sweetness and savory backbone; sweat until translucent to create a softer texture and balance stronger flavors in the broth.
  • 1/2 medium bell pepper, green Dice finely to contribute a slightly bitter, vegetal note and crisp texture; sauté with aromatics to mellow its flavor while enhancing overall complexity.
  • 1 medium carrot Grate or dice finely to introduce natural sweetness and earthiness; cook until tender to add body and subtle caramelized flavor that complements the tomato base.
  • 1/2 medium zucchini Cube or dice small to add moisture and mild, slightly sweet flavor; simmer until softened so it melds into the broth without becoming mushy.
  • 1 medium tomato, red Dice medium to provide fresh acidity and bright tomato flavor; cook down to release juices and balance the richness of meat and tomato paste.
  • 1 teaspoon olive oil Measure and heat briefly to coat the pot for sautéing; use to prevent sticking and to carry fat-soluble flavors from aromatics into the soup.
  • 1 pound ground beef or turkey Brown thoroughly to develop savory, umami-rich flavor and a hearty texture; break into small pieces while cooking to distribute meaty richness throughout the soup.
  • 1/4 cup lentils, raw Rinse and add raw to boost protein and fiber while absorbing flavors; cook until tender so it thickens the broth and adds subtle earthiness.
  • 2 teaspoon Italian Seasoning Measure and add to season the soup with a blend of Mediterranean herbs; use during cooking to impart warm, herbaceous notes that complement tomatoes and meat.
  • 3/4 teaspoons salt Measure and add to enhance overall seasoning and bring out other flavors; adjust to taste during cooking to ensure balanced saltiness.
  • 1/4 teaspoon onion powder Measure and sprinkle to enhance savory notes and round out onion flavor; combine with other seasonings for consistent seasoning throughout the soup.
  • 1/4 teaspoon garlic powder Measure and sprinkle to strengthen garlic aroma and deepen savory flavor; use alongside fresh garlic for layered garlic profile without overpowering.
  • 1 can (6 oz) tomato paste, canned Spoon in to intensify concentrated tomato flavor and thicken the broth; stir well to incorporate and boost umami and richness throughout the soup.
  • 3 cup vegetable broth Pour in to create a flavorful cooking liquid and control soup consistency; choose vegetable broth for a balanced, savory, and slightly sweet base.
  • 8 ounce lasagna noodles, dry Break into pieces and add to cook until tender, absorbing flavors and contributing pasta texture; monitor cooking time carefully to avoid over-softening.
  • 1/4 teaspoon black pepper, ground Measure and season to add warm, slightly floral heat and to balance sweetness; adjust to taste to achieve a mild peppery background.
  • 1/4 teaspoon red pepper/chili flakes Measure and use sparingly to introduce a touch of heat and lively finish; sprinkle according to desired spice level to brighten the soup.
  • 1 tablespoon nutritional yeast Stir in to provide a nutty, savory boost and add subtle umami; sprinkle during or after cooking to enrich flavor without dairy.
  • 1 cup spinach Tear or chop and add near the end to contribute fresh, leafy texture and a mild, slightly mineral flavor; wilt briefly to preserve color and nutrients.
  • 4 ounce mozzarella cheese Shred or cube and use as a melty topping to add creamy, salty, stretchy texture; melt into bowls for traditional lasagna-like richness.
  • 2 cup grapes Rinse and serve as a fresh, sweet palate cleanser or side; offer chilled grapes to provide a contrasting cool sweetness beside the savory soup.

Instructions
 

  • Mince garlic; chop onion, bell pepper, carrot and zucchini; dice tomato.: The first scents you will notice are bright and vegetal as the fresh garlic and onion release their aroma while you chop, the air filling with a promising savory perfume. Good knife work ensures even cooking, so aim for consistent sizes so no single vegetable overcooks. A common mistake here is uneven chopping which causes some pieces to become limp while others stay raw, so take a moment to size-match pieces. Keep a small bowl to collect scraps to keep your workspace tidy and to prevent missing any piece that should go in the pot later.
  • Heat oil in your Instant pot on saute mode. Once hot, add onion and garlic. Cook for 2 minutes, stirring occasionally. Add ground beef or turkey and saute until mostly cooked.: As the olive oil shimmers, it will carry the fragrance of the onion and garlic outward, and you should hear a gentle sizzle when they hit the surface. The sound will deepen when you add the ground beef or turkey , and you want to achieve browning that adds caramelized notes. Browning develops complex flavor through the Maillard reaction, which is vital for a lasagna style base. Avoid overcrowding the pot which traps steam and prevents browning, a frequent misstep. If the meat steams instead of browns, lift it out briefly and give the pot a quick scrape to encourage fond formation, that browned residue contains concentrated flavor.
  • Add bell pepper, carrot and zucchini; stir together. Add red lentils, tomato, Italian seasoning, salt, onion powder, garlic powder and tomato paste; whisk together while pouring in broth.: As you fold in the chopped vegetables they will hiss and briefly pop, releasing sweeter and greener notes; the tomato paste will darken and deepen as you whisk, creating a thick ribbon of concentrated tomato. Pouring the vegetable broth deglazes the pot, lifting browned bits off the bottom into the liquid, which is essential for a rich soup. This integration adds body and harmonizes flavors quickly. A common mistake is dumping broth too rapidly which can cause splatter or uneven incorporation; pour steadily while whisking to emulsify the paste. If you notice clumps of paste, take a moment to whisk until smooth so the texture of the soup remains silky.
  • Break lasagna noodles into small pieces and add to Instant Pot; stir to combine.: When you break the lasagna noodles into the pot, they will initially float and then soften as they hydrate, releasing a faint toasted pasta scent. Stirring helps prevent clumping and ensures each piece submerges to cook evenly. The broken noodle pieces will impart a comforting thickness as they release starch while cooking. A common error is not breaking noodles small enough which leads to long strands that can tangle, so aim for two to three inch pieces. If the noodles seem to stick together, gently separate them with a spoon to ensure an even texture throughout the soup.
  • Close the lid and set to high pressure cook for 3 minutes. Let the pressure release naturally for 10 minutes, then carefully do a quick release if there is still pressure in the pot.: During pressure cooking you will notice the pot going quiet as flavors concentrate, the steam carrying rich tomato and meat aromas. The short high pressure burst is enough to tenderize the pasta and meld flavors quickly while keeping textures lively. Natural release allows residual heat to finish cooking gently, preventing an overcooked, mushy pasta. A common mistake is performing an immediate quick release which can agitate the soup and overcook delicate pieces, so always wait the recommended natural release before finishing with a quick release if needed. Use oven mitts and a long utensil for safety when venting.
  • Mix in the black pepper, red pepper flakes, and nutritional yeast. Taste and adjust seasonings, if desired.: At this stage the aroma will be rounded and savory, and when you stir in black pepper and red pepper flakes a gentle warmth will bloom. Nutritional yeast adds a savory, slightly cheesy lift that complements the meat and tomato. Tasting now is crucial because heat concentrates flavors; adjust salt and heat sparingly. A frequent slip is over-salting early, so taste before adding more salt or spices. If it tastes flat, a splash more broth or a pinch of salt can brighten it quickly.
  • Fold in the spinach and sprinkle shredded mozzarella over the top; let it sit for a few minutes to allow the spinach to wilt and the cheese to melt. Serve with grapes.: When you fold in the handful of spinach it will instantly wilt into glossy, tender ribbons, offering a fresh green contrast. The shredded mozzarella cheese melts slowly into creamy pockets, pulling gentle strings when scooped. Letting the bowl rest gives the textures a chance to settle and flavors to marry. A common mistake is stirring vigorously after adding cheese which can break the silkiness, so allow it to sit undisturbed for a couple minutes. Serve alongside the crisp grapes for a juicy, sweet counterpoint that refreshes the palate after rich bites.

Notes

  • Prep mise en place. Having the garlic, chopped onion, and diced vegetables ready before you heat the pot prevents overcooking and keeps the sauté stage quick and controlled.
  • Toast tomato paste briefly. After adding the paste, cook it for a minute with the aromatics to deepen its flavor and reduce raw acidity for a more rounded broth.
  • Deglaze properly. Pour a bit of the vegetable broth while scraping the bottom to lift browned bits, which intensifies the soup’s base flavor.
  • Adjust lentil timing if needed. If your lentils are older they may take slightly longer to cook; check texture after pressure release and allow a few extra minutes off heat if necessary.
  • Cheese finish matters. Use shredded mozzarella cheese and let it melt undisturbed for a creamier finish rather than stirring it vigorously into the hot soup.
  • Serve grapes chilled. Cooling the grapes before serving creates a pleasant temperature contrast that brightens the meal.
