- Celery (2 ribs, diced): Provides crunch and a subtle aromatic flavor.
- Zucchini (1 medium, diced): Offers a delicate texture and flavor that softens as it cooks.
- Garlic (4 cloves, minced): Adds a pungent kick and enhances all other flavors.
- Diced tomatoes (1 can, 14.5 oz): Brings tanginess and a rich tomato flavor.
- Vegetable broth (4 cups): The savory base that ties all the ingredients together.
- Canned cannellini beans (1 can, drained and rinsed): Adds protein and creaminess.

Cooking Instructions
-
Prepare The Vegetables
Start by dicing your onion, carrot, celery, and zucchini into bite-sized pieces. Mince the garlic as well. These fresh vegetables will form the aromatic base of your soup.
-
Sauté (Optional But Recommended)
Heat the olive oil in a skillet over medium heat. Add the onion, carrot, and celery, and sauté for about 5-7 minutes until the onions are translucent and the vegetables start to soften. Stir in the garlic and cook for an additional minute, just until fragrant. This step enhances the flavors and adds a bit of caramelization.
-
Transfer To The Slow Cooker
Add the sautéed vegetables to the slow cooker. Then, pour in the diced tomatoes (with juice), vegetable broth, and bay leaves. Stir to combine.
-
Add Beans And Pasta
Toss in the cannellini beans, kidney beans, green beans, and pasta. The beans provide protein, and the pasta will soak up the flavors and become tender as it cooks.
-
Season It Up
Sprinkle in the Italian seasoning, salt, and pepper. Give everything a good stir, making sure the pasta is submerged in the broth.
-
Cook
Set your slow cooker to low and cook for 6-7 hours, or high for about 3-4 hours. The goal is to have the vegetables tender, the pasta cooked through, and the flavors melded together beautifully.
-
Add Spinach
About 30 minutes before serving, stir in the spinach. It will wilt quickly and turn the soup a beautiful green while adding some extra nutrients.
-
Final Touch
Once done, taste the soup and adjust seasonings if needed. Serve hot, garnished with a generous sprinkle of grated Parmesan cheese.
Ingredient Insights
- Beans: Beans are a cornerstone of minestrone. They contribute not only to the texture but also to the soup’s heartiness. The combination of cannellini and kidney beans provides both a smooth and a slightly firmer texture, creating a balanced bite.
- Pasta: The small pasta shapes, like elbow macaroni or ditalini, absorb the broth, becoming a comforting part of each spoonful. You can use gluten-free pasta if needed, though be mindful of the cooking time.
- Spinach: Leafy greens like spinach are an essential part of any minestrone, adding freshness and nutrition. When added at the end, they retain their vibrant color and delicate flavor, which balances out the heartiness of the beans and pasta.
Expert Tips
- Don’t Overcook the Pasta: Pasta in the slow cooker can get mushy if overcooked. Add it at the right time (about 3 hours before serving on high, or 30 minutes before serving on low), and you’ll get perfectly tender pasta without the soggy texture.
- Seasoning Is Key: Be generous with the Italian seasoning, salt, and pepper. Taste test periodically throughout cooking. Because slow cooking melds flavors, you might need to adjust the seasoning closer to serving.
- Layering Flavors: If you want even more depth of flavor, consider adding a small Parmesan rind to the slow cooker along with the other ingredients. The rind will melt into the broth, infusing it with a savory richness.
- Consistency: If your soup becomes too thick, simply add a little more vegetable broth or water. It’s always easier to thin out a soup than to thicken it.
Recipe Variations
- Meat Lovers’ Minestrone: Add ground turkey, sausage, or pancetta for an extra layer of flavor. Brown the meat in a skillet and add it to the slow cooker with the other ingredients.
- Gluten-Free Version: Use gluten-free pasta, and check your broth for any gluten ingredients. You can also serve the soup with a side of gluten-free bread to soak up the delicious broth.
- Tomato-Based: For a more classic tomato-forward flavor, increase the number of tomatoes or use crushed tomatoes instead of diced. This gives the soup a more tomato-centric base.
- Spicy Minestrone: If you love a little heat, add some red pepper flakes or a chopped jalapeño. It’ll give the soup a nice kick without overpowering the other flavors.

Minestrone soup is a celebration of fresh, wholesome ingredients that come together to create a filling, flavorful meal.
