One-Pot Lasagna Soup Recipe tastes like a cozy bowl of cheesy, saucy lasagna that decided to ditch the casserole dish and jump into a soup pot instead. It works perfectly for busy home cooks who want big Italian comfort in about 40–45 minutes, with minimal dishes and maximum flavor. I first made this on a cold Tuesday when I felt lazy but still wanted something that tasted like I tried hard.

Ingredients You Need
Main ingredients
- 1 tablespoon olive oil
- 1 pound Italian sausage, casings removed
- Use mild or hot based on your heat preference.
- Swap with ground beef, ground turkey, or a mix if you like.
- 1 small onion, diced
- 3 cloves garlic, minced
- 1 tablespoon tomato paste
- I like the double-concentrated tube from Cento or Mutti for easy storage.
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1 teaspoon dried parsley
- 1 teaspoon sugar
- This balances acidity in the tomatoes.
- 1 teaspoon kosher salt, plus more to taste
- 1 teaspoon black pepper
- 1 teaspoon crushed red pepper flakes
- Optional, adjust to your spice comfort level.
- 1 can (28 ounces) crushed tomatoes
- Use a good brand like San Marzano style for richer flavor.
- 4 cups low-sodium chicken broth or vegetable broth
- Low-sodium broth lets you control seasoning.
- 2 cups water
- 8–10 lasagna noodles, broken into bite-size pieces
- Use regular or oven-ready; adjust simmer time slightly if oven-ready.
- 1 cup small pasta shapes (optional, if you want it extra hearty)
- Ditalini, small shells, or elbow pasta work well.
Cheese topping
- 1 cup ricotta cheese
- 1 cup shredded mozzarella cheese
- 1/4 cup grated Parmesan cheese
- 1 tablespoon chopped fresh parsley or basil
- Pinch of salt and pepper
Mix these in a small bowl right before serving to make a creamy, cheesy dollop for each bowl.
Pantry shortcuts and substitutions
- Use jarred marinara instead of crushed tomatoes and tomato paste if you want a shortcut.
- Use Italian seasoning blend instead of separate dried herbs if that is what you have.
- Use cottage cheese instead of ricotta if you prefer more protein and a lighter feel.
- Use gluten free lasagna noodles and pasta if you need a gluten free version.
Equipment list
- Large heavy-bottomed pot or Dutch oven (at least 5–6 quarts)
- Wooden spoon or spatula
- Ladle for serving
- Small bowl for cheese mixture
- Measuring cups and spoons
Tips & Mistakes
- Brown the sausage well so you build flavor on the bottom of the pot instead of rushing this step.
- Drain excess fat if the sausage releases a lot, so the soup does not taste greasy.
- Sauté the onion until it softens and turns lightly golden to deepen flavor.
- Add garlic after the onion softens so the garlic does not burn and turn bitter.
- Toast the tomato paste for 1–2 minutes so it tastes rich instead of metallic.
- Season in layers, not just at the end, so the broth tastes full and balanced.
- Break lasagna noodles into similar sizes so they cook evenly.
- Stir often after you add noodles so they do not stick to the bottom of the pot.
- Do not overcook the pasta or it will turn mushy and soak up too much broth.
- Keep extra broth or water nearby so you can thin the soup if it thickens too much.
- Add the cheese mixture to individual bowls, not the pot, so leftovers reheat better.
- Taste before serving and adjust salt, pepper, or red pepper flakes to your liking.
How to Make One-Pot Lasagna Soup Recipe
Step 1: Brown the sausage
Heat the olive oil in your large pot over medium high heat. Add the Italian sausage and break it into small crumbles with your spoon. Cook until the sausage browns and no pink remains, about 5–7 minutes.
If the sausage releases a lot of fat, spoon out some so you keep about 1 tablespoon in the pot. Keep the browned bits on the bottom because they add flavor.
Step 2: Sauté onion and garlic
Add the diced onion to the pot with the sausage. Stir and cook until the onion softens and turns lightly golden, about 4–5 minutes. Add the minced garlic and cook 30–60 seconds, just until fragrant.
Do not walk away during this part because garlic can burn quickly. Stir often and lower the heat slightly if it starts to brown too fast.
Step 3: Build the tomato base
Add the tomato paste to the pot and stir it into the sausage and onion mixture. Cook it for about 1–2 minutes so it darkens slightly and smells sweet and rich. Add the dried oregano, basil, parsley, sugar, salt, black pepper, and red pepper flakes.
Stir well so the spices coat the sausage and onion. This step wakes up the dried herbs and builds a strong base for the soup.
Step 4: Add liquids and simmer
Pour in the crushed tomatoes, chicken broth, and water. Scrape the bottom of the pot with your spoon to release any browned bits into the liquid. Stir everything together and bring it to a gentle boil.
Once it boils, lower the heat to a steady simmer. Let it cook for about 10 minutes so the flavors blend and the broth tastes rich.
Step 5: Add lasagna noodles and pasta
Add the broken lasagna noodles and any extra small pasta you use. Stir well so the noodles spread evenly and do not clump. Keep the soup at a steady simmer, not a hard boil.
Cook, stirring often, until the noodles turn al dente, usually 12–15 minutes. Taste a noodle to check doneness and adjust the cooking time as needed.
Step 6: Adjust thickness and seasoning
Check the thickness of the soup. If it looks too thick, add a bit more broth or water until it reaches your favorite soup consistency. If it looks too thin, let it simmer a few more minutes so the noodles release more starch and thicken it.
Taste the broth and add more salt, pepper, or red pepper flakes if you want a stronger kick. Turn off the heat once the noodles taste tender but not soft.
Step 7: Mix the cheese topping
While the soup simmers, stir together the ricotta, mozzarella, Parmesan, chopped parsley or basil, and a pinch of salt and pepper in a small bowl. Mix until it turns creamy and spreadable. This mixture will melt into the hot soup and give that classic lasagna vibe.
Keep this bowl in the fridge if your kitchen runs hot, so the cheese stays fresh. Pull it out right before serving.
Step 8: Serve
Ladle the hot One-Pot Lasagna Soup into bowls. Add a generous spoonful of the cheese mixture on top of each bowl. The heat from the soup will soften the cheese and make it melty and creamy.
Sprinkle extra Parmesan and herbs on top if you feel fancy. Serve right away while it steams and smells like an Italian restaurant in your kitchen.
Variations I've Tried
I swap half the sausage with ground turkey when I want a slightly lighter version that still tastes hearty. I use spinach or kale stirred in during the last 5 minutes for a veggie boost that wilts nicely into the broth. I add sliced mushrooms with the onion when I want more umami and a meatier feel without extra meat.
I use a mix of sausage and ground beef when I want it to taste closer to classic lasagna. I swap in gluten free noodles and broth when cooking for gluten free friends, and it still tastes rich and comforting. I sometimes use a dollop of pesto instead of dried herbs for a fresh, herby twist that feels special.
How to Serve One-Pot Lasagna Soup Recipe
Serve this One-Pot Lasagna Soup Recipe steaming hot with a big spoon and maybe a piece of garlic bread or crusty bread to scoop up the cheesy bits. Add a simple green salad on the side to balance the richness and add some crunch. Kids usually love this because it tastes like lasagna but feels easier to eat.
Top each bowl with extra Parmesan, fresh basil, or a sprinkle of red pepper flakes for those who like heat. If you host a casual dinner, set out the cheese mixture and toppings so everyone customizes their own bowl.
How to store
- Cool the soup to room temperature, then store it in airtight containers in the fridge for up to 4 days.
- Store the cheese mixture in a separate container in the fridge for up to 4 days so it stays fresh and does not melt into the soup.
- Freeze the soup without the cheese topping for up to 3 months in freezer safe containers, leaving a little space at the top for expansion.
- Reheat on the stove over medium heat, adding a splash of broth or water if it thickened, and stir often until hot.
- Reheat single portions in the microwave in 60–90 second bursts, stirring between each, then top with fresh cheese mixture right before serving.
