The pressure builds and you start counting down minutes until you eat. You notice the pot starting to hiss as the valve signals it's almost time for the quick release. That broth depth is gonna be just right, and you can't wait to dive in.

In those last few minutes, the aroma of herbs and cream kinda takes over your kitchen. You catch the scent of oregano and thyme mixing with the garlic. It’s like a warm hug is waiting for you right in your pressure cooker.
Then you sense the valve hiss as the pressure starts to release naturally. You know the natural release time is just enough to keep the chicken juicy and the soup rich. You recall the effort it took to break up those lasagne sheets but trust me, it works real good in this creamy white lasagna soup.
Why This Recipe Works Every Single Time
- The pressure cooker seals in all those yummy flavors, so nothing gets lost or watered down.
- Using a quick release on the valve keeps the chicken tender but not overcooked. For tips on handling quick release safely, check out our pressure cooker safety tips.
- The broth depth is perfect with the mix of chicken stock and cream giving it a rich texture.
- Breaking the lasagna sheets into pieces spreads the pasta love evenly throughout your soup bowl.
- Fresh herbs and spices pop just right when cooked under pressure, making this soup anything but boring.
All the Pieces for This Meal
Okay, you gotta make sure you gather everything before starting. Here’s what you need:
- 1 tablespoon olive oil
- 2 tablespoons unsalted butter
- 1 lb chicken breast, chunked up
- 1 large shallot, finely diced
- ½ lb sliced closed cup mushrooms
- 2 large garlic cloves, minced
- 1 teaspoon each dried oregano, dried basil, fresh or dried thyme
- ½ teaspoon red chili flakes for a little kick
- 2 tablespoons plain flour
- 5 cups chicken stock and 1 ½ cups single cream (half and half)
- Broken lasagna sheets or mafalda corta pasta, about 5 oz
- Baby spinach and cream cheese for that cheesy finish
- Grated Parmesan and salt and pepper to taste
Each one plays a part in that creamy, comforting flavor you’d expect. Don’t rush the dicing or slicing either. Taking care here really pays off.

The Exact Process From Start to Finish
First, heat your olive oil and butter in the pot on medium heat till the butter’s all melted. You wanna get it nice and hot before adding the chicken.
Next, toss in the chicken pieces and let them cook for about 5 to 7 minutes. You gotta brown them a bit; that’s where the great taste starts forming.
Then, add your diced shallot and cook till it softens, just 2 to 3 minutes. This part builds flavor, so don’t skip it or rush it.
Time to add the mushrooms. Cook them until they start to release their moisture and get a little brown, about 5 minutes. You’ll see the steam rising and smell it filling your kitchen.
Now, throw in minced garlic with all the herbs and red chili flakes. Cook that for just a minute until you can really smell all those spices mingle together.
Finally, sprinkle in your flour and stir well so it blends. Pour in the chicken stock and cream, then break in your lasagna sheets. Bring everything to a boil, close the lid, and let the pressure build. Set your timer to cook for about 8 minutes.
When the cooking is done, go for a natural release for about 5 minutes, then quick release the rest. Open your pot and stir in the baby spinach, cream cheese, and Parmesan. Season with salt and pepper, then serve hot.
Easy Tweaks That Make Life Simple
- You can skip the fresh herbs and double up dried if that’s what you got. Or try dried oregano from our 25minute baked ground beef meatballs recipe which uses dried herbs well.
- Frozen chicken breast pieces work fine if you’re in a hurry; add a couple more minutes to cooking time.
- Substitute cream cheese with mascarpone or ricotta if you wanna switch it up.
- If breaking lasagna sheets feels like a hassle, try small pasta shapes like ditalini or small shells.
These tweaks won't mess up the cozy feel of this soup but can totally save you some prep time.
That First Bite Moment
You ladle your soup into a bowl and see the creamy white color with little chunks of chicken and pasta. You notice the steam swirling up, carrying hints of herbs and cheese.
The first spoonful hits your tongue with warmth and just the right amount of creaminess. You catch the slight tang of the cream cheese blending with the Parmesan.
Then you feel the soft bite of tender chicken, mingling with the spinach leaves that add a fresh green surprise in every mouthful.
And the little red chili flakes kinda sneak in to give you a gentle wake-up buzz. It’s comfort in a bowl that you’ll wanna come back to again and again.

Keeping Leftovers Fresh and Ready
Once you got leftovers, cool that soup down before popping it in the fridge. That keeps bacteria away and stops weird flavors from forming.
Store your creamy white lasagna soup in an airtight container for up to 3 days. Just reheat it gently on the stove so the cream doesn’t split.
If you want it longer, freeze it in smaller portions. Make sure you leave some room at the top because the liquid expands when frozen.
When reheating from frozen, thaw overnight in the fridge if you can. Warm it slowly on low heat while stirring now and then so it heats evenly.
Everything Else You Wondered About
- Can I use beef instead of chicken? You can, but cooking time might need a bit longer for the beef to get tender.
- Is it okay to add veggies like carrots or celery? Totally! Add them with shallots to soften before pressure cooking.
- Can I make this soup vegan? You’d need to swap chicken and dairy for plant-based broth and cream alternatives.
- What pasta works best? Broken lasagna sheets or short pastas like mafalda corta work best because they cook evenly in the broth.
- Why natural release then quick release? Natural release helps keep the chicken tender and soup creamy before you finish with quick release to stop cooking.
- How thick should the soup be? You want it creamy and a bit thick but still spoonable. Adjust by adding more stock or cream if it’s too thick.
