- Dairy-free finish: Skip Parmesan and top with nutritional yeast or a drizzle of good olive oil.
- Low-sodium version: Choose low-sodium broth and no-salt-added tomatoes, then season to taste at the end.
FAQ
Can I make this soup without pasta?
Yes.
It’s still hearty with beans and vegetables. If you want extra bulk, add diced potatoes early on or stir in cooked rice or quinoa before serving.
Which gluten-free pasta holds up best?
Brown rice and corn blends keep their shape best in soup. Chickpea pasta is fine but can get soft if overcooked.
Always add it near the end and cook just to al dente.
Can I cook this on the stovetop?
Absolutely. Sauté onion, carrot, and celery in olive oil, then add the rest (except pasta and greens). Simmer 25–30 minutes, add pasta until al dente, then stir in greens and finish with acid.
How do I keep the broth from getting too thick?
Use enough liquid at the start and add more broth or water as needed when reheating.
If pasta soaks up too much, cook it separately and add it to each bowl.
Is this recipe vegetarian or vegan?
It’s naturally vegetarian if you use vegetable broth. To keep it vegan, skip the Parmesan or use a dairy-free alternative.
What if my soup is too acidic?
Balance it with a pinch of sugar or a splash of extra olive oil. You can also add a bit more broth to mellow the tomatoes.

This gluten-free crockpot minestrone is simple, nourishing, and adaptable.
With everyday ingredients and minimal effort, you get a big pot of flavorful soup that fits a range of diets. Use pasta or not, tweak the vegetables, and make it your own. It’s a cozy staple you’ll come back to again and again.
