Ingredients and Smart Substitutions

Gathering the ingredients is straightforward—most are everyday items you’ll find at any grocery store. Here’s what you’ll need for 6 servings:

• 2 tablespoons olive oil (or vegetable broth for oil-free)
• 1 medium sweet onion, chopped
• 4 cloves garlic, minced
• 2 stalks celery, sliced
• 2 large carrots, peeled and chopped
• 1 medium zucchini, diced (sub: yellow squash, potatoes, or butternut squash)
• 28 ounces canned diced tomatoes (with juices)
• 4 cups vegetable broth (homemade or low-sodium store-bought)
• 1/2 teaspoon dried oregano
• 1/2 teaspoon dried thyme
• 1 teaspoon dried basil (or 2 teaspoons Italian seasoning)
• 15-ounce can small white beans, drained and rinsed (cannellini or chickpeas)
• 15-ounce can kidney beans, drained and rinsed (or black/pinto beans, great for vegan burritos)
• 1/2 cup frozen or fresh green beans (or peas)
• 1/2 cup small shell pasta (gluten-free if needed, like ditalini or macaroni)
• 2 cups baby spinach (sub: kale, chard, or collards)
• Salt and pepper to taste
• Optional: 2-3 tablespoons chopped fresh parsley and vegan parmesan for garnish

These beans add about 12g of protein per serving, making it a balanced meal.

For gluten-free, opt for certified GF pasta—brands like Barilla work well.

Step-by-Step Instructions

Making this soup is as easy as it gets—one pot means minimal cleanup. Follow these steps for success:

1. Heat 2 tablespoons olive oil in a large pot over medium heat. Add the chopped onion, minced garlic, sliced celery, chopped carrots, and diced zucchini. Sauté for 5-10 minutes until the vegetables soften and release their aromas—this builds the flavor base.
2. Stir in the canned diced tomatoes (with juices), vegetable broth, dried oregano, thyme, basil, drained white beans, kidney beans, green beans, and pasta. Bring the mixture to a boil, then reduce heat to a simmer. Cook uncovered for 10-15 minutes, stirring occasionally, until the pasta is al dente.
3. Add the baby spinach and stir until it wilts, about 1-2 minutes. Taste and season with salt and pepper. If it’s too thick, add a splash of broth; if too thin, simmer longer.
4. Ladle into bowls, garnish with fresh parsley and a sprinkle of vegan parmesan if desired. Serve hot with crusty bread.

Total time: 40 minutes (15 prep, 25 cook). Pro tip: Chop veggies uniformly for even cooking.

Expert Tips for the Perfect Soup

As a registered dietitian specializing in plant-based eating, I’ve perfected this recipe over years of testing. Here are my top tips to elevate your minestrone:

• Sauté first: This step caramelizes the veggies, adding depth without extra calories. Skipping it can make the soup taste flat.
• Don’t overcook the pasta: Add it toward the end to keep it from getting mushy. If storing leftovers, cook pasta separately and stir in when reheating.
• Build flavor layers: Fresh herbs at the end brighten it up. For extra umami, add a bay leaf during simmering (remove before serving).
• Thicken naturally: The pasta starch and beans create a hearty texture—no need for cream. If you want it thicker, mash a few beans against the pot side. This soup is naturally high in fiber, aiding digestion as per USDA guidelines.

Storage, Freezing, and Meal Prep

This soup is a meal prep dream—make a batch on Sunday and enjoy all week. Store in an airtight container in the fridge for up to 4 days.

For best texture, keep pasta separate if possible. To reheat: Microwave or stovetop with a bit of water or broth to loosen it up.

Avoid boiling to prevent mushiness. Freezing: Yes, but freeze without the pasta and spinach (add fresh when reheating).

Portion into freezer bags for up to 3 months. Thaw overnight in the fridge.

Meal prep idea: Divide into 6 mason jars for grab-and-go lunches. It’s freezer-friendly and reheats beautifully, saving time on busy days. According to the Academy of Nutrition and Dietetics, freezing soups is a great way to preserve nutrients.

Fun Variations and Serving Ideas

Keep things exciting by tweaking the recipe:

• Seasonal twist: In fall, add diced butternut squash or sweet potatoes for earthiness.
• Protein power: Stir in cooked lentils (like in our creamy red lentil dahl) or tempeh for extra staying power.
• Spicy kick: Add red pepper flakes or a dash of hot sauce.
• Creamy version: Blend a portion and stir back in, or top with cashew cream.

Serving suggestions: Pair with garlic bread, a side salad, or grilled cheese on sourdough. For a complete meal, add a sprinkle of nutritional yeast for B12.
