What Ingredients You Will Need

This slow cooker vegetable soup is all about simple, wholesome ingredients coming together in a perfect harmony of flavors. You probably already have many of these items in your pantry or fridge!

• Carrots: Peeled and sliced into thin rounds (adds a natural sweetness).
• Celery: Chopped into bite-sized pieces (adds crunch and flavor).

• Tomatoes: Diced or crushed (canned or fresh, depending on what you have).
• Zucchini: Sliced into rounds (perfect for a tender yet slightly firm texture).
• Green beans: Trimmed and cut into smaller pieces (adds a nice pop of color and crunch).
• Vegetable broth: I recommend using low-sodium broth for better control over the saltiness.
• Garlic: Minced or grated (because everything tastes better with garlic!).
• Dried thyme: A pinch adds earthy depth to the soup.
• Dried oregano: For that classic herbaceous flavor.
• Salt and pepper: To taste (start small, you can always add more).
• Bay leaves: Adds a warm, aromatic layer to the broth.
• Olive oil: A drizzle enhances the flavor and helps the vegetables shine.
• Optional Add-Ins: Fresh parsley for garnish, a squeeze of lemon for brightness, or a sprinkle of Parmesan cheese for richness.

If you don’t have a slow cooker, don’t worry—you can easily adapt this recipe for stovetop cooking using a large pot or Dutch oven.

Preparation Method

1. Prep the Veggies: Wash, peel, and chop all your vegetables into bite-sized pieces. This will ensure even cooking.
2. Layer Ingredients: Add the potatoes, carrots, celery, onion, green beans, zucchini, and tomatoes to the slow cooker.
3. Add Seasonings: Sprinkle the minced garlic, dried thyme, oregano, salt, and pepper over the vegetables. Toss gently to combine.
4. Add Broth: Pour in the vegetable broth until it covers the vegetables completely. Add the bay leaves for extra flavor.
5. Cook: Set your slow cooker to low and let it cook for 6-8 hours, or high for 3-4 hours. The vegetables should be tender but not mushy.
6. Check Seasoning: Taste the soup about 30 minutes before it’s done and adjust seasoning if needed.
7. Finish: Remove the bay leaves and stir in optional add-ins like fresh parsley or a squeeze of lemon juice for brightness.
8. Serve: Ladle the soup into bowls and, if desired, top with Parmesan cheese or a dollop of sour cream.

This soup is best served warm, but leftovers can easily be reheated for quick lunches or dinners throughout the week.
