FAQs

Can I make this soup vegetarian?

Yes! Just omit the chicken and use vegetable broth. You can add more mushrooms or cannellini beans for heartiness.

Can I use oven-ready lasagna noodles?

It’s not recommended—they may not cook evenly or absorb flavors properly in soup.

What’s the best way to make this in the slow cooker?

Melt butter and flour in the crockpot first, then add ingredients and cook on low for 6–8 hours or high for 4–5 hours. Add noodles and cream in the last 15–20 minutes.

Can I substitute the prosciutto?

Yes, crispy bacon or pancetta work well too. Or omit it for a vegetarian version.

Can I use shredded rotisserie chicken?

Yes. Skip the cooking step for chicken and add it after the broth has simmered.

How do I prevent the cheese from clumping?

Is coconut milk noticeable in the flavor?

Not strongly—it adds creaminess without a strong coconut taste, especially if using full-fat.

Can I make this soup ahead?

What’s the best pot to use?

A large Dutch oven is ideal for stovetop cooking—it retains heat and is perfect for one-pot meals.
