This comforting soup delivers everything you crave in traditional lasagna — seasoned meat, tomatoes, herbs, tender noodles, and melty cheese — but in a much easier, one-pot format. Even better, it’s naturally gluten-free (when using gluten-free noodles) and can easily be made dairy-free if needed.

It’s a perfect weeknight dinner, ideal for meal prep, and makes enough to feed the whole family.

Why You’ll Love This Gluten-Free Lasagna Soup

Traditional lasagna is delicious but time-consuming. Between boiling noodles, preparing layers, and baking for nearly an hour, it’s not always realistic on a busy night.

This soup simplifies everything:

• One pot
• No layering
• No oven required
• Ready in 30 minutes
• Perfect for leftovers

The flavor is just as rich and satisfying as classic lasagna. The broth becomes thick and hearty from the tomatoes and pasta, while the combination of beef and sausage adds depth and savory richness.

It’s comfort food — without the extra work.

Ingredients You’ll Need (With Substitutions)

Scroll down to the recipe card for exact measurements.

Olive Oil

Used to sauté the aromatics. Extra virgin olive oil adds great flavor, but avocado oil works well too.

Onion and Garlic

These create the flavor base of the soup. Fresh garlic gives the best taste.

Ground Beef

Lean ground beef is ideal. You can substitute:

• Ground turkey
• Ground chicken

For a lighter version.

Italian Sausage

Adds bold flavor and a slight kick. Remove the casing before cooking.
You can:

• Use mild sausage instead of spicy
• Omit it completely if preferred

Canned Crushed Tomatoes

These provide body and a rich tomato base.

Canned Diced Tomatoes

Add texture and a more traditional lasagna-style consistency.

Broth

Chicken, beef, or vegetable broth all work well. Use low-sodium if you want more control over seasoning.

Italian Seasoning

A blend of dried herbs that gives that classic Italian flavor.

Red Pepper Flakes

Optional, but they add a subtle heat.

Sea Salt and Black Pepper

Adjust to taste, especially if adding extra broth later.

Fresh Basil

Brightens the entire dish and adds freshness.

Gluten-Free Lasagna Noodles

Break them into smaller pieces before adding. Any gluten-free pasta works if lasagna noodles aren’t available.

Fresh Spinach (Optional)

An easy way to add extra nutrients. It wilts quickly and blends right in.

Optional Cheese Toppings

For serving:

• Parmesan
• Mozzarella
• Ricotta or cottage cheese

If dairy-free, simply skip or use plant-based alternatives.

Kitchen Tools You’ll Need

• Large Dutch oven or heavy-bottomed pot
• Wooden spoon or spatula
• Measuring cups and spoons

How to Make Gluten-Free Lasagna Soup (Stovetop Method)

1. Sauté the Aromatics

Heat olive oil in a large Dutch oven over medium heat. Add diced onion and cook for 2–3 minutes until softened. Stir in minced garlic and cook until fragrant.

2. Brown the Meat

Add ground beef and sausage. Cook until no pink remains, breaking it apart as it cooks. Drain excess fat if necessary.

3. Add Tomatoes and Broth

Stir in crushed tomatoes, diced tomatoes, broth, Italian seasoning, red pepper flakes, salt, pepper, and fresh basil. Bring the mixture to a gentle boil.

4. Simmer

Reduce heat and let simmer for about 10 minutes to allow flavors to develop.

5. Add the Noodles

Break lasagna noodles into bite-sized pieces and stir them into the pot. Simmer for 15–20 minutes, or until pasta is tender. Add more broth if needed.

6. Finish with Spinach

If using spinach, stir it in during the last minute of cooking and let it wilt.

7. Serve

Ladle into bowls and top with cheese and extra basil if desired. Serve warm.

Slow Cooker Option

If you prefer a set-it-and-forget-it method:

1. Brown onion, garlic, beef, and sausage in a skillet.
2. Transfer to slow cooker.
3. Add tomatoes, broth, and seasonings (but not pasta or spinach).
4. Cook on low for 8 hours or high for 3 hours.
5. Cook pasta separately until al dente.
6. Stir pasta and spinach into the slow cooker and cook 10 more minutes before serving.

Instant Pot Method

1. Use sauté mode to cook onion, garlic, and meat.
2. Add tomatoes, broth, seasonings, and broken noodles.
3. Seal lid and cook on high pressure for 7–8 minutes.
4. Allow 10-minute natural release, then quick release remaining pressure.
5. Stir in spinach and serve.

Tips for Success

• Pasta absorbs broth as it sits. Add extra broth when reheating.
• Break noodles into small pieces for even cooking.
• Taste and adjust seasoning after adding additional liquid.
• For meal prep, consider storing pasta separately to prevent it from becoming too soft.

Serving Suggestions

This soup is hearty enough to stand alone, but it pairs beautifully with:

• Gluten-free garlic bread
• Garlic breadsticks
• Simple Caesar salad
• Roasted green beans

Storage and Freezing

Refrigeration

Store leftovers in an airtight container for 3–5 days. Add broth when reheating.

Freezing

For best results, freeze without the noodles. Store up to 3 months. Thaw overnight in the refrigerator, then cook fresh noodles and add when reheating.
