Equipment You’ll Need for This Slow Cooker Minestrone Soup
To get started, you’ll need a slow cooker. I recommend one with a minimum capacity of 6 quarts so there’s plenty of room for all the delicious ingredients. If you don’t already own one, look for a programmable version with a “Keep Warm” setting for added convenience. Here are some tips to get the best results:
- Use the low setting when you have more time (6-8 hours) for a richer flavor.
- If you’re in a rush, the high setting cuts the cook time to just 3-4 hours.
- A parmesan rind added to the soup gives it a savory boost while it simmers—don’t skip it!
Simple Ingredients for Slow Cooker Minestrone Soup
This easy minestrone soup recipe uses pantry staples and fresh veggies to create something truly special. Here are a few heroes you don’t want to miss:
- Beans: Two types—red kidney and great northern beans—add protein and a hearty texture. Canned versions are a huge time-saver.
- Sun-dried tomato pesto: This secret ingredient enhances the tomato base with an intense depth of flavor. You can use store-bought or homemade.
- Frozen green beans: No chopping required, and they hold their texture even after cooking.
- Parmesan rind: Adds an umami richness as it slowly infuses the soup. Don’t toss those rinds—save them for soups like this!
Pro Tip: Keep pre-chopped veggies and frozen spinach on hand to make prep even faster.

Jake’s Tips for the Best Slow Cooker Minestrone Soup
- Save time during prep: Use pre-diced frozen vegetables or buy a pre-chopped mirepoix blend (carrots, celery, onions).
- Batch cook: Double the recipe and freeze portions for up to 3 months.
- Storage tip: Keep pasta separate until serving to avoid it soaking up all the broth in leftovers.
- Reheat like a pro: Add a splash of vegetable stock or water when reheating soup to revive its consistency.
- Avoid mushy pasta: For meal prep, cook pasta separately and add it just before eating.
Quick Ways to Switch Up This Slow Cooker Minestrone Soup
- Make it gluten-free: Swap the ditalini pasta for your favorite gluten-free variety or quinoa.
- Add protein: Stir in shredded chicken or cooked Italian sausage during the final 20 minutes of cooking.
- Use up leftovers: Toss in any veggies you have on hand—sweet potatoes, kale, or bell peppers all work beautifully.
- Spicy twist: Add a pinch of red pepper flakes for a little heat.
