Ingredients:
- 1 large yellow onion, finely diced
- 3 medium carrots, peeled and sliced into rounds
- 2 stalks celery, sliced
- 4 cloves garlic, minced
- 2 tablespoons tomato paste
- 6 cups high-quality vegetable broth
- 1 can (28 oz) crushed fire-roasted tomatoes
- 1 can (15 oz) dark red kidney beans, drained and rinsed
- 1 can (15 oz) cannellini beans, drained and rinsed
- 1 large Parmesan cheese rind (approx. 2-3 inches)
- 1 tablespoon dried Italian seasoning
- 1 teaspoon sea salt
- 1/2 teaspoon cracked black pepper
- 1.5 cups zucchini, diced into half-moons
- 1 cup fresh green beans, trimmed and cut into 1-inch pieces
- 1 cup ditalini pasta, uncooked
- 2 cups fresh baby spinach, packed
- 1 tablespoon fresh lemon juice
Instructions:
- Prep the aromatics. Dice the yellow onion, slice the carrots into rounds, and chop the celery. Note: Keeping these uniform in size ensures they all finish cooking at the same time.
- Combine the base. Place the onion, carrots, celery, minced garlic, and tomato paste into the slow cooker insert.
- Add the liquids and beans. Pour in the 6 cups of vegetable broth, the crushed fire roasted tomatoes, the kidney beans, and the cannellini beans.
- Season the pot. Add the dried Italian seasoning, sea salt, black pepper, and the Parmesan cheese rind. Note: Submerge the rind completely in the liquid to maximize flavor extraction.
- Begin the slow cook. Cover and cook on Low for 5 hours and 30 minutes, until the carrots are tender but still hold their shape.
- Introduce the fresh vegetables. Stir in the diced zucchini and green beans during the last 45 minutes of cooking. Note: This prevents these softer vegetables from becoming a mushy mess.
- Add the pasta. Pour in the 1 cup of ditalini pasta. Cover and cook for an additional 20 to 30 minutes until the pasta is al dente and the broth has thickened slightly.
- Wilt the greens. Turn off the slow cooker and stir in the 2 cups of fresh baby spinach. Note: The residual heat is enough to wilt the spinach in about 2 minutes.
- The final brighten. Stir in the 1 tablespoon of fresh lemon juice and remove the Parmesan rind.
- Taste and adjust. Give it a final taste; you might need an extra pinch of salt now that the pasta has absorbed some of the liquid.
