Step by Step Instructions
Step 1: Prep and Chop Vegetables
Set out your large soup pot and gather your prep tools. Wash and dry the vegetables. Slice carrots and celery into even coins and half-moons so they cook uniformly. Chop the yellow onion and snip green beans into bite-size pieces. Break cauliflower into small florets. Keep garlic minced finely. Uniform chopping ensures your vegetable soup cooks evenly and each bite has a pleasant texture. If you prefer a thicker soup, chop the veggies a bit smaller. For a chunkier feel, keep them larger. Prep everything before turning on the burner so the cooking process flows smoothly.
Step 2: Sauté Aromatics for Flavor
Place the large soup pot over medium heat and add the olive oil. Once shimmering, stir in the chopped yellow onion and cook for 3 to 4 minutes until translucent. Add the minced garlic and cook for another 30 seconds, stirring constantly to prevent burning. This quick sauté builds a savory foundation for your hearty vegetable soup. You will smell the aromas blooming, which means you are on the right track. The goal is a gentle browning, not crisping, so adjust the heat if things move too fast. Keep the wooden spoon handy to scrape the bottom of the pot.
Step 3: Build the Broth Base
Add the sliced carrots and celery to the pot and sauté for 3 minutes to start softening. Pour in the vegetable broth and the can of diced tomatoes with their juices. Increase the heat to bring the mixture to a gentle boil, then reduce to a steady simmer. Season with salt and black pepper. As it simmers, the flavors meld into a cohesive, comforting base. This is the moment your vegetable soup starts to become something special. If you enjoy a brighter tomato note, stir in a pinch of dried oregano or basil. For a deeper savory profile, add a bay leaf.
Step 4: Add Cauliflower and Green Beans
Once the broth has simmered for about 8 minutes and the carrots are beginning to soften, add the cauliflower florets and chopped green beans. These vegetables need less time to cook, so adding them later keeps their color and texture vibrant. Simmer for another 8 to 10 minutes until the cauliflower is tender-crisp and the green beans are bright green. Taste the broth and adjust salt and pepper as needed. Your hearty vegetable soup should feel balanced: sweet from the carrots, savory from the broth, and fresh from the greens. Stir gently to distribute heat evenly.
Step 5: Rest and Serve Thoughtfully
Turn off the heat and let the soup rest for 5 minutes. This short rest allows flavors to settle and the broth to clarify. Skim any surface foam if present, and remove any bay leaf you may have added. Ladle the soup into warm bowls, making sure each serving gets a variety of vegetables. This vegetable soup shines with crusty bread, a sprinkle of fresh herbs, or a drizzle of olive oil. If you are meal prepping, cool completely before storing. For more cozy ideas, browse our Hearty Soup Recipes to inspire your next batch.
Tips
- For a richer broth, add a Parmesan rind during simmer and remove before serving.
- Boost umami by stirring in a teaspoon of tomato paste with the garlic.
- Use frozen vegetables if fresh are unavailable; add them later in the simmer.
- Make it heartier with beans or small pasta; adjust liquid and cooking time accordingly.
- Brighten the finish with a squeeze of lemon juice or a splash of apple cider vinegar.
- Store leftovers in airtight containers; the vegetable soup keeps 4 days in the fridge.
