Ingredients
Ingredient | Quantity |
---|---|
Onion (chopped) | 1 medium |
Carrots (diced) | 2 medium |
Celery stalks (diced) | 2 |
Zucchini (diced) | 1 medium |
Kidney beans (drained, rinsed) | 1 can (14 oz) |
Diced tomatoes | 1 can (14 oz) |
Vegetable broth | 4 cups |
Dried basil | 1 teaspoon |
Dried oregano | 1 teaspoon |
Small pasta (e.g., ditalini) | 1 cup |
Salt and pepper | To taste |
Fresh parsley (optional) | For garnish |
Ingredient Notes:
- Ditalini, elbows, or shells work best for small pasta shapes. For gluten-free, use GF pasta or rice.
- Use low-sodium vegetable broth to better control salt levels.
- Substitute kidney beans with cannellini, chickpeas, or black beans for variety.
- Add green beans, spinach, kale, or corn for seasonal flair.
Equipment Needed
- Crockpot / Slow Cooker: Slowly melds all the flavors together while cooking vegetables and pasta to perfection.
- Cutting board & knife: For prepping fresh vegetables.
- Ladle: For clean and easy serving.
- Measuring cups/spoons: Ensures accurate broth and herb quantities.
A slow cooker is essential for convenience—it brings out the sweetness in vegetables and allows flavors to develop deeply without constant monitoring.
Step-by-Step Instructions
- Begin by chopping the onion, carrots, celery, and zucchini into small, even pieces. Rinse and drain the kidney beans.
- Add the prepared vegetables, beans, diced tomatoes (with their juice), vegetable broth, basil, and oregano to your crockpot. Stir to combine and season with salt and pepper.
- Cover and cook on low for 6 to 7 hours or high for 3 to 4 hours. The vegetables should be tender and the broth fragrant and savory.
- About 30 minutes before serving, stir in the small pasta. Continue cooking on high until the pasta is tender, stirring occasionally to prevent sticking.
- Once done, taste and adjust seasoning if needed. Ladle into bowls and top with chopped fresh parsley for a pop of color and freshness.

Tips and Variations
Cooking Tips:
- If you’re using gluten-free pasta, consider cooking it separately and adding it just before serving to prevent it from becoming mushy.
- For a thicker broth, mash a few of the beans into the soup.
- Stir occasionally after adding pasta to ensure it cooks evenly and doesn’t clump.
Flavor Enhancements:
- Add a parmesan rind during cooking for extra richness and umami.
- A squeeze of lemon juice or balsamic vinegar at the end brightens the flavors.
- For a smoky note, toss in some fire-roasted tomatoes or a hint of smoked paprika.
Customizations:
- Protein Boost: Add cooked sausage, shredded chicken, or plant-based sausage.
- Green Goodness: Stir in spinach, kale, or Swiss chard during the last 10 minutes.
- Grain Swap: Substitute pasta with farro, barley, or quinoa for a heartier variation.
Serving Suggestions
Serve minestrone in wide, shallow bowls to show off the colorful array of vegetables and pasta. A sprinkle of fresh parsley or a dollop of pesto makes a stunning visual (and flavor) enhancement.
Pair it with warm, crusty Italian bread or garlic toast for dipping. A side Caesar salad or marinated olives and roasted red peppers creates a lovely Mediterranean-inspired spread.
For a rustic presentation, ladle the soup into earthenware bowls and place a small bowl of grated parmesan or nutritional yeast on the table for guests to garnish as they please.
Pairings
This flavorful, vegetable-forward soup is best paired with light and herbaceous drinks that refresh the palate:
- Chianti or Pinot Noir—light-bodied reds that complement the tomato base without overpowering.
- A crisp white wine like Vermentino or Sauvignon Blanc cuts through the richness of the broth.
- For non-alcoholic options, try a sparkling lemon soda, herbal iced tea, or a simple mint-infused water.
These pairings elevate the meal and harmonize with the fresh, herbal tones in the soup.
Storage and Reheating
Cool the soup completely before storing. It will keep well in the refrigerator for up to 5 days.
For freezing, store in airtight containers for up to 3 months. If making ahead, consider leaving the pasta out until reheating, as it can become overly soft after thawing.
Reheat on the stove over medium heat or microwave in intervals, stirring occasionally. Add extra broth or water as needed, since pasta may absorb more liquid during storage.
