Ingredients You’ll Need

Protein

• 1 pound Italian sausage, casings removed
  • Use mild for kids or spicy if you like heat.
  • Swap with ground turkey, chicken, or plant-based crumbles if you prefer.
• Optional: 4 slices thick-cut bacon, chopped, for extra smoky flavor

Aromatics & Veggies

• 1 medium yellow onion, diced
• 3 cloves garlic, minced
• 1 medium carrot, diced small (adds sweetness and body)
• 1 rib celery, diced (optional, but adds nice flavor)
• 1 tablespoon tomato paste
• 1 teaspoon Italian seasoning
• 1 teaspoon dried basil
• ½ teaspoon dried oregano
• ¼–½ teaspoon crushed red pepper flakes, to taste

Liquids & Tomatoes

• 1 can (28 ounces) crushed tomatoes
  • Use a quality brand like Cento or Muir Glen for richer flavor.
• 4 cups low-sodium chicken broth or vegetable broth
• 1 cup water, plus more as needed to thin the soup

Pasta

• 8–10 lasagna noodles, broken into bite-size pieces
  • Use regular, not no-boil, for best texture.
  • You can swap with mafalda, bowties, or rotini if that is what you have in the pantry.

Cheesy “Lasagna” Topping

• 1 cup whole milk ricotta cheese
• 1 cup shredded mozzarella cheese
• ¼ cup grated Parmesan or Pecorino Romano
• 1 tablespoon chopped fresh parsley or basil
• Pinch of salt and black pepper

Seasonings & Pantry Staples

• 2 tablespoons olive oil
• 1–1½ teaspoons kosher salt, plus more to taste
• ½ teaspoon freshly ground black pepper
• 1 teaspoon sugar (optional, to balance acidity if your tomatoes taste sharp)

Optional Add-ins & Substitutions

• 1–2 cups fresh spinach or chopped kale, stirred in at the end
• ½ cup heavy cream for a richer, creamier broth
• Use gluten-free lasagna noodles if you need a gluten-free version
• Use plant-based sausage and vegetable broth for a meatless option

Equipment

• Large heavy-bottomed pot or Dutch oven (at least 5–6 quarts)
• Wooden spoon or spatula
• Ladle
• Small bowl for mixing the cheese topping
• Measuring cups and spoons

Tips & Tricks

• Brown the sausage well so you build deep flavor in the pot before you add any liquid.
• Break the lasagna noodles into similar-sized pieces so they cook evenly and fit nicely on a spoon.
• Keep the soup at a gentle simmer after adding pasta so the noodles cook through without turning mushy.
• Stir the pot often once the pasta goes in so the noodles do not stick to the bottom.
• Taste the broth before serving and adjust salt, pepper, and red pepper flakes at the end.
• Add spinach or kale during the last 2–3 minutes of cooking so the greens stay bright and tender.
• Mix the cheese topping in a separate bowl and add it to each bowl of soup instead of the whole pot so leftovers reheat better.
• If the soup thickens too much as it sits, stir in a splash of broth or water while you reheat it.

How to Make One Pot Lasagna Soup Recipe

Step 1: Sauté veggies and aromatics

Heat olive oil in a large stock pot or Dutch oven over medium heat. Add the sausage and chopped bacon if using, and cook until browned and cooked through, about 6–8 minutes, breaking it into crumbles as it cooks. Add the diced onion, carrot, and celery, and cook until the veggies soften and the onion turns translucent, about 5–7 minutes. Stir in the garlic, tomato paste, Italian seasoning, dried basil, dried oregano, and crushed red pepper flakes, and cook 1–2 minutes until the tomato paste darkens slightly and the mixture smells fragrant.

Step 2: Build the flavorful broth

Pour in the crushed tomatoes, chicken or vegetable broth, and water, and scrape up any browned bits from the bottom of the pot. Stir everything together and bring the mixture to a gentle boil over medium-high heat. Taste the broth and add salt, pepper, and sugar if the tomatoes taste too acidic. Reduce the heat to medium-low so the soup simmers steadily.

Step 3: Add the pasta

Add the broken lasagna noodles to the simmering soup and stir well so the pieces spread out. Cook the noodles uncovered at a gentle simmer for 10–12 minutes, stirring every couple of minutes so they do not clump or stick. Check a noodle piece for doneness and cook a bit longer if you want a softer texture. Add a splash of water or broth if the soup thickens more than you like while the pasta cooks.

Step 4: Finish the soup

Stir in spinach or kale if you use it and cook 2–3 minutes until the greens wilt. Taste again and adjust salt, pepper, and red pepper flakes so the flavor hits just right. If you want a creamier lasagna soup, stir in heavy cream and let it heat through for 1–2 minutes. Turn off the heat and let the soup sit for 5 minutes so the flavors settle and the noodles finish hydrating.

Step 5: Mix the cheesy topping

While the soup rests, mix the ricotta, mozzarella, Parmesan, chopped parsley or basil, salt, and pepper in a small bowl. Stir until the mixture looks creamy and spreadable, almost like a thick dip. Taste and adjust seasoning so it tastes salty and cheesy enough, since this topping seasons each bowl.

Step 6: Serve like a bowl of lasagna

Ladle hot lasagna soup into bowls. Add a generous scoop of the ricotta mixture on top of each bowl, and let it melt slightly into the soup. Swirl the cheese into the broth with your spoon so you get a bit of cheesy goodness in every bite. Finish with extra herbs or Parmesan if you feel fancy on a weeknight.

What to Serve with One Pot Lasagna Soup Recipe

Serve this One Pot Lasagna Soup Recipe with a simple green salad tossed with olive oil, lemon, and a pinch of salt for a fresh contrast. Add warm garlic bread or toasted baguette slices so everyone can scoop up the cheesy broth. Steamed broccoli or roasted vegetables pair nicely and keep the meal balanced. Offer sparkling water, flavored seltzer, or iced tea for a refreshing drink that cuts through the richness.

Storage Options

• Store leftover lasagna soup in an airtight container in the fridge for up to 4 days, and keep the cheese mixture in a separate container.
• Chill the soup completely, then freeze it in freezer-safe containers for up to 2 months, leaving a little space at the top for expansion.
• Reheat the soup gently on the stove over medium-low heat, adding a splash of broth or water if it thickens, or use the microwave in short bursts, stirring between each.
• Add the ricotta topping to each bowl after reheating so the cheese stays creamy and does not overcook.
