The BEST Lasagna Soup (One-Pot, Cheesy, and Weeknight-Easy)

Lasagna is incredible but let’s be real. You’re not spending a Tuesday night boiling noodles, browning meat, making béchamel, and playing Tetris with cheese layers. This lasagna soup delivers everything you love about classic lasagna – rich meat sauce, tender noodles, and creamy cheese – without layering, baking, or babysitting a pan. One pot. One hour. Real comfort food that fits your schedule.

The difference between boring soup and one you’ll crave is all in the technique. Brown the meat hard to build fond (a step most people rush). Bloom the garlic and Italian seasoning in that fat. Toast the tomato paste and bouillon paste until they darken and smell sweet – that’s where depth lives. Then add marinara, fire-roasted tomatoes, and beef broth, drop the noodles right into the pot, and let them soak up every ounce of flavor. Finish each bowl with ricotta mixed with Parmesan and basil for the ultimate cheat code: every layer of lasagna, zero assembly required.

This recipe lives in our comfort food soups for a reason – it’s built for real dinners, not weekend projects.

🔪 Ingredients for Lasagna Soup

The Soup

Olive oil – For browning the meat and building flavor
Ground beef – Use 80/20 for richness without excess grease
Italian sausage – Sweet or hot, both work; adds depth you can’t fake (though we’re always partial to hot)…
Yellow onion, diced – Classic base flavor
Green bell pepper, diced – Traditional lasagna-adjacent flavor; adds sweetness
Garlic, minced – Fresh only; jarred gets muddy here
Italian seasoning – One blend keeps things simple
Kosher salt – Season in layers
Black pepper – Adds background heat
Crushed red pepper flakes – Optional, but recommended
Tomato paste – Must be cooked until brick-red for depth
Chicken bouillon paste – Boosts savory flavor without extra liquid
Marinara sauce – Use one you already like; it sets the tone
Fire-roasted diced tomatoes – Adds smoky tomato backbone
Low-sodium beef broth – Lets you control salt
Bay leaf – Quiet background flavor
Lasagna noodles, broken – Rustic bites > perfect squares
Fresh parsley – Brightens everything at the end

Ricotta Topping

Whole-milk ricotta – Creamy, not grainy
Parmesan – Salty, nutty balance
Kosher salt – Just enough to wake it up
Fresh basil – Clean herbal finish
Shredded mozzarella – Melts into the soup, not the bowl

Equipment

Large heavy-bottomed pot or Dutch oven
Wooden spoon
Small bowl (for ricotta topping)

📝 Step-by-Step Instructions: How to Make Lasagna Soup

Brown the meat. Heat olive oil in a large pot over medium heat. Add the sausage and beef. Cook until about halfway browned.
Build the base. Add onion and bell pepper. Cook until the meat finishes browning and the vegetables soften, about 6 minutes.
Bloom the seasoning. Stir in garlic, Italian seasoning, salt, black pepper, and red pepper flakes. Cook 30 seconds, just until fragrant.
Cook the pastes. Add tomato paste and chicken bouillon paste. Stir constantly for 1 minute so they caramelize instead of scorching.
Add the liquids. Pour in marinara, fire-roasted tomatoes (with juices), beef broth, and bay leaf. Bring to a gentle simmer.
Cook the noodles. Add broken lasagna noodles and stir well so nothing sticks. Simmer 10–12 minutes, stirring often, until noodles are tender.
Finish the soup. Remove bay leaf. Stir in parsley. Taste and adjust seasoning.
Mix the ricotta topping. In a small bowl, combine ricotta, Parmesan, salt, and basil.
Serve. Ladle soup into bowls. Top with shredded mozzarella, then add a spoonful of ricotta mixture and let it melt in.

🔄 Substitutions & Variations

Skip the sausage and use all ground beef if preferred.
Use hot Italian sausage for extra heat.
Cook noodles separately if you want firmer texture for leftovers.
Swap ground turkey for a lighter option (season aggressively).

💡 Meat Nerd Tips

Cooking the tomato paste until it darkens removes the raw tomato bite and adds depth. Don’t rush it.
Bouillon paste isn’t cheating—it’s concentrated flavor insurance, especially in soups with a lot of starch.
Breaking lasagna noodles by hand gives you uneven edges that feel more like real lasagna bites.
Brown the meat properly – color equals flavor – not just grey steamed meat.
Stir continuously after adding tomato paste and bouillon paste so they don’t burn.
Then, stir immediately after adding noodles to prevent clumping.
Use a marinara you already like; it’s part of the final flavor.
Add the mozzarella first, so the heat of the soup melts it before the ricotta goes on.
