Pro Tips
- Add the pasta near the end so it stays tender and doesn’t soak up too much broth.
- Cut the vegetables into similar-sized pieces so they cook evenly.
- Stir the spinach in at the very end. It wilts fast from the hot soup.
- If the soup gets too thick after sitting, stir in extra broth before serving.
- Fresh parmesan on top adds a lot of flavor, so don’t skip it.
Substitutions and Variations
- Use ditalini pasta instead of elbow pasta.
- Add red beans or cannellini beans instead of great northern beans.
- Swap spinach for kale.
- Add cooked ground turkey or sausage for extra protein.
- Use chicken broth if you are not keeping it vegetarian.
Make Ahead Tips
- Chop all vegetables the night before and keep them in the fridge.
- The soup base can be slow cooked ahead of time. Add pasta and spinach before serving.
- Freeze the soup without the pasta for the best texture.
Why This Recipe Works (Quick Science)
Slow cooking gives the vegetables time to release flavor into the broth. The tomato paste thickens the soup and adds rich flavor. Beans add starch, which helps make the broth taste creamy without cream. Cooking the pasta separately at the end keeps it from getting too soft.
Recipe Instructions
Step 1: Add the Vegetables to the Crockpot
Add 1 cup diced onion, 1 cup diced carrots, 1 cup diced celery, 3 cloves minced garlic, 1 diced zucchini, and 1 cup cut green beans into the black oval crockpot.
Step 2: Add the Broth and Seasonings
Pour in 4 cups vegetable broth and 2 cups water. Add 1 can diced tomatoes, 1 can drained kidney beans, 1 can drained great northern beans, 2 tablespoons tomato paste, 2 tablespoons olive oil, 1 teaspoon salt, 1 teaspoon Italian seasoning, and 1/2 teaspoon black pepper. Stir everything together well.
Step 3: Slow Cook the Soup
Cover the crockpot with the lid and cook on LOW for 6 to 7 hours or HIGH for 4 hours until the vegetables are tender.
Step 4: Add the Pasta
Stir 1 cup elbow pasta into the hot soup. Cover and cook on HIGH for 20 to 25 minutes until the pasta is tender.
Step 5: Stir in the Spinach
Add 2 cups fresh spinach and stir until wilted, about 2 minutes.
Step 6: Serve the Soup
Ladle the hot soup into round white bowls and top with grated parmesan cheese before serving (optional).
