Let’s make a pot that keeps you warm, happy, and coming back for “just one more bowl.”

Ingredients You’ll Need

Here’s a handy table breaking down each ingredient used in the white chicken lasagna soup and why it’s essential in the recipe. This isn’t just a list, it’s a guide to what each item brings to the pot.

Ingredient	Amount	Purpose & Notes
Onion (diced)	1 medium	Builds flavor from the start. Sautéed onions create a sweet, savory base. Optional if you’re not a fan.
Garlic (minced)	1 tablespoon	Adds depth and aroma. Garlic and onion are the ultimate soup-starting duo.
Italian Seasoning	1 tsp (or to taste)	Brings in lasagna vibes with oregano, basil, and thyme.
Salt, Pepper, Garlic Blend (e.g. Kinders)	1 tsp (or to taste)	All-in-one seasoning boost. Adjust based on your blend.
Red Pepper Flakes	A pinch	Adds a subtle kick. Use more if you like heat.
Complete Seasoning	½–1 tsp	Adds instant flavor with herbs, spices, and umami. Optional, but makes a difference.
All-Purpose Flour	2 tablespoons	Thickens the broth slightly so it’s creamy without being too heavy. Cook it 3-4 minutes to remove raw taste.
Chicken Broth	6 cups	The soup’s liquid base. Use low-sodium for better seasoning control.
Shredded Chicken (rotisserie recommended)	2 cups	Rotisserie chicken makes this easy and flavorful. Cooked, shredded chicken saves time.
Spinach (frozen, thawed)	2 cups	Adds color and nutrients. You can also use fresh spinach just stir it in near the end.
Lasagna Noodles (broken)	8 noodles	Adds color and nutrients. You can also use fresh spinach, just stir it in near the end.
Heavy Whipping Cream	1 cup	Thickens the broth slightly so it’s creamy without being too heavy. Cook it for 3-4 minutes to remove the raw taste.
Cream Cheese	4 oz (half a block)	Melts into the soup, making it extra smooth and cheesy. Adds body and tang.
Parmesan Cheese (shredded)	6 oz	Salty, nutty flavor booster. Melts beautifully and deepens the taste.
Mozzarella Cheese (shredded)	8 oz	For that melty, gooey, lasagna cheese-pull moment. Adjust to your liking.
Black Pepper & Seasoned Salt	To taste	Adds color and nutrients. You can also use fresh spinach; stir it in near the end.

Tools That Make It Easier

You don’t need fancy stuff. But these help:

• A large pot or Dutch oven
• A wooden spoon for stirring
• A ladle for serving
• A knife + cutting board
• A measuring cup (or eyeballing confidence)

The Step-by-Step White Chicken Lasagna Soup Method

This soup is one of those recipes that feels like you did a lot… but you really didn’t. It’s a one-pot situation. It’s cozy. It’s creamy. It’s packed with chicken and noodles.

And the best part? You don’t have to layer anything like traditional lasagna. You’re basically making lasagna “in sweats.”

The whole method is simple: build flavor first, thicken the base, add broth, add the “lasagna” noodles, then finish with cream and cheese.

Each step has a purpose. Once you understand why you’re doing it, you’ll make this soup like it’s muscle memory.

Let’s walk through it exactly, step by step.

Step 1: Sauté the onion and garlic

Start with a large pot on medium heat. You want enough space for six cups of broth and everything else. No tiny pot today.

Add your diced onion first. This is your flavor foundation. As it cooks, it softens and releases that sweet, savory smell that makes people walk into the kitchen and ask, “What are you making?”

If you don’t like onions, you can skip them. But honestly? Onion makes the soup taste more “finished.” It gives the base a deeper, richer flavor. Think of it like background music. You don’t notice it directly, but you miss it when it’s gone.

Let the onion cook for a few minutes until it looks a little glossy and soft.

Now add minced garlic. Garlic cooks fast, so don’t throw it in too early. Stir it for about 30 seconds to a minute. The goal is fragrance, not browning.

Next comes seasoning. The subtitle method adds seasonings early so the onion and garlic soak up all that flavor. Add:

• Italian seasoning
• a salt-pepper-garlic blend
• red pepper flakes (just a little for a kick)
• complete seasoning (optional but helpful)

Stir everything well. This step should already smell incredible. Like, “I might be done cooking,” great.

Step 2: Add flour to build a creamy base

This is where the soup starts getting that creamy, lasagna-style texture without needing a complicated sauce.

Sprinkle in 2 tablespoons of all-purpose flour and stir it into the onion-garlic mixture. The flour will coat everything and look a little pasty. That’s normal.

Now here’s the critical part: cook the flour for 3 to 4 minutes.

Why? Because raw flour tastes like… raw flour. And you don’t want that. Cooking it for a few minutes removes that “flour taste” and makes your base taste smoother and richer later.

Think of this step like warming up your engine before driving. You can skip it, but the ride won’t feel right.

Keep stirring so nothing sticks or burns.

Step 3: Pour in chicken broth and bring it to a simmer

Once the flour has cooked, it’s time to turn that seasoned mixture into a soup base.

Slowly pour in your chicken broth while stirring. The subtitle method uses 6 cups total. Stir as you pour so the flour blends smoothly into the broth.

At first, it may look cloudy. That’s fine. As it heats up, it will smooth out and start thickening slightly.

Bring it to a gentle simmer. You don’t need a raging boil yet. Just get it hot enough so it’s bubbling lightly.

This is the point where your pot starts looking like “real soup,” and everything begins to come together fast.

Step 4: Break up the lasagna noodles

While the broth is heating, prep your noodles.

Break 8 lasagna noodles into pieces. Don’t overthink it. The subtitle method literally breaks them into random sizes. Some pieces will be long, some short, some weird. That’s perfect.

This soup is not trying to be fancy. It’s trying to be comforting.

Broken noodles give you that “lasagna bite” feel without layering. Every spoonful has a few noodle pieces, which makes the soup feel hearty.

Set your broken noodles aside. You’ll add them once the pot is ready.

Step 5: Add chicken and spinach

Now add your shredded chicken. The subtitle method suggests rotisserie chicken because it’s quick and already flavorful. You’ll want about 2 cups of shredded.

Rotisserie chicken is the cheat code here. No boiling. No baking. No extra pan. Shred and go.

Next, add spinach. The method uses 2 cups, and it’s thawed frozen spinach. Frozen works great because it’s already soft and easy to stir in.

Stir everything, then let the pot return to a gentle simmer.

The key detail from the subtitle: don’t add noodles while the pot is still cool from adding chicken and spinach. Let it warm back up so your noodles cook properly.

At this stage, the soup is already looking “cute,” but don’t judge it yet. You’re still building.

Step 6: Add noodles and let them soften

Once your soup is back at a simmer, add those broken lasagna noodles.

Stir well right away so noodles don’t clump together. Noodles tend to stick together if you ignore them. So give them attention early.

Let the soup cook until the noodles are soft and tender. This usually takes about 10–12 minutes, depending on noodle thickness and the strength of your simmer.

Stir occasionally while they cook. This prevents sticking on the bottom of the pot and helps noodles cook evenly.

This is where the soup becomes a full meal. The noodles soak up flavor, and the pot starts to look thick and comforting.

Step 7: Pour in heavy cream and melt the cream cheese

Now we go from “nice soup” to “lasagna soup.”

Pour in 1 cup heavy whipping cream. Stir it in gently. You’ll see the broth turn creamy immediately.

Next, add cream cheese. The subtitle method uses half a block, which is 4 ounces.

Drop it in and stir. It won’t melt instantly. Give it a few minutes. It will soften and blend into the soup.

Cream cheese is doing a lot here:

• It adds richness
• It adds body
• It makes the soup silky
• It gives that “white lasagna” taste

Once it melts, your soup base will look thicker, smoother, and more luxurious.

Step 8: Turn the heat down and add parmesan

This step is crucial. Cheese does not like high heat.

Turn your stove down before adding shredded Parmesan. Keep it on low or medium-low.

Now add parmesan cheese. The subtitle method uses a 6-ounce bag.

Stir it in slowly until it melts fully. Parmesan adds salty depth and that classic Italian comfort taste. It makes the soup taste like it’s been cooking longer than it has.

Once it’s melted, the soup will smell even better. “Don’t talk to me until I get a bowl” is better.

Step 9: Add mozzarella for that cheesy finish

Now bring in the cheese pull.

Add 8 ounces of mozzarella cheese and stir gently until it melts.

Mozzarella is what gives you that gooey, stretchy, lasagna-style melt. It turns the soup into something that feels indulgent, like a cozy cheat meal but still homemade.

Important: keep the heat low. If the pot is boiling hard, cheese can turn grainy or stringy in a weird way. Low heat lets it melt smoothly.

Once melted, let the soup simmer gently for a few minutes to blend everything.

Step 10: Taste and adjust seasoning

Now taste your soup. This is your final polish step.

The subtitle method adds:

• a little black pepper
• a little seasoned salt

You don’t have to add both. Taste first. Some broths and cheeses are salty already.

Adjust slowly. Add a pinch, stir, taste again. This keeps you from over-salting.

When it tastes rich, creamy, and balanced like cheesy lasagna in spoon form, you’re done.

Serve it hot. And if you can, make toast on the side. Dipping bread into this soup is not optional. It’s a lifestyle.

Practical Tips for White Chicken Lasagna Soup

These aren’t just random tips; they come straight from the cooking experience outlined in the original step-by-step process. They’ll help you avoid common pitfalls and make your soup even better.

1. Don’t Skip Cooking the Flour

When you add the flour to the sautéed onions and garlic, let it cook for 3 to 4 minutes. This step removes that raw, pasty taste and builds a creamy, silky soup base. If you rush this, the final soup might taste off.

2. Use Rotisserie Chicken to Save Time

The easiest shortcut? Use store-bought rotisserie chicken. It’s juicy, already seasoned, and ready to shred. You’ll save at least 20 minutes and still get a flavorful result.

3. Break the Noodles by Hand

No need to dirty a knife. Just snap 8 lasagna noodles into uneven pieces with your hands. This gives the soup a rustic, homemade texture like lasagna without the layering.

4. Keep the Heat Low When Adding Cheese

Once the cream cheese, parmesan, and mozzarella go in, reduce the heat to low. High heat can make the cheese clump or turn gritty. Low and slow helps everything melt smoothly.

5. Stir Frequently After Adding Noodles

Lasagna noodles like to stick. Stir every 2-3 minutes to keep them separated and evenly cooked. This ensures each bite gets the perfect soft-chewy texture.

Serving Ideas That Make It Even Better

You’ve made the soup, now take it to the next level with how you serve it. A few little touches make it feel like a complete, comforting meal.

1. Garlic Bread or Toast

The classic. A piece of garlic toast on the side is mandatory for dipping. It soaks up that creamy broth and makes every spoonful feel luxurious.

2. Topping Bar for Fun

Let everyone top their own bowl:

• Extra parmesan
• Red pepper flakes
• Cracked black pepper
• Fresh chopped parsley

This turns dinner into a cozy, interactive experience, especially great for guests or kids.

3. Pair with a Simple Salad

To balance the richness, serve with a light green salad. Something like arugula, spinach, or spring mix with lemon vinaigrette is perfect.

4. Serve in a Bread Bowl (Optional, but Fun)

Want to get fancy? Hollow out a round loaf and pour the soup inside. It’s hearty, Insta-worthy, and gives full-on lasagna energy.

Easy Variations (Make It Yours)

This soup is incredibly flexible. Here’s a table of fun ways you can tweak the original recipe to suit your taste or what you have in the fridge:

Swap This	With This Instead	Why It Works
Rotisserie chicken	Leftover turkey, grilled chicken, or baked chicken	Great for post-holiday leftovers or meal prep
Frozen spinach	Fresh baby spinach, kale, or chopped broccoli	Adds variety, nutrients, and freshness
Lasagna noodles	Bowtie pasta, broken spaghetti, or egg noodles	Still gives a “pasta soup” vibe with a twist
Mozzarella cheese	Provolone, Monterey Jack, or Italian blend	Switch up the melty texture and flavor
Parmesan	Pecorino Romano or Asiago	For a sharper, saltier bite
Red pepper flakes	Smoked paprika or cayenne pepper	Adjusts heat level with different flavors
Cream cheese	Ricotta or mascarpone	Both melt into a creamy base with a unique twist
Chicken broth	Vegetable broth	Makes it vegetarian (if skipping chicken)
