Ina Garten’s Vegetarian Lentil Vegetable Soup: A Hearty Classic

My grandmother, bless her heart, wasn’t much of a cook. Her repertoire consisted mainly of boiled vegetables and overcooked roasts. But there was one exception, one dish that she made with love and that I remember vividly: a thick, comforting lentil soup. It wasn’t fancy, but it was nourishing and satisfying, especially on cold winter days. This lentil vegetable soup, inspired by Ina Garten’s version and lovingly adapted to be vegetarian, brings me right back to her cozy kitchen, the aroma of simmering lentils filling the air, and a sense of warmth that only homemade soup can provide. This recipe captures that same comforting essence.

Recipe Overview

• Prep Time: 35 minutes
• Cook Time: 1 hour 30 minutes
• Total Time: 2 hour 5 minutes
• Servings: 8-10
• Yield: About 4 quarts
• Dietary Type: Vegetarian (can be made vegan)

Ingredients

• 1 lb french green lentils (or brown lentils)
• 4 cups yellow onions, diced small (about 3 large onions)
• 4 cups leeks, white part only, diced small (2-3 leeks – if unavailable, substitute with 8 scallions, using both the green and white parts)
• 1/2 cup red bell pepper, diced small (optional)
• 1 tablespoon minced garlic (about 3 cloves)
• 1/4 cup good olive oil, plus additional for drizzling on top
• 1 tablespoon kosher salt (if using regular salt, reduce to about 1 1/2 teaspoons)
• 1 – 1 1/2 teaspoons freshly ground black pepper (start with 1 teaspoon and adjust to taste)
• 1 tablespoon minced fresh thyme leaves (or 1 teaspoon dried)
• 1/2 – 1 teaspoon ground cumin (optional: substitute with curry powder or chili powder for a change)
• 3 cups small diced celery (about 8 stalks)
• 3 cups small diced carrots (about 4 to 6 carrots)
• 3 quarts vegetable stock
• 1/4 cup tomato paste
• 1-2 bay leaves
• 2 tablespoons red wine vinegar (or red wine)
• Freshly grated Parmesan cheese (optional, omit for vegan)

Equipment Needed

• Large bowl
• Large stockpot (at least 7 quarts)
• Cutting board
• Sharp knife
• Measuring cups and spoons

Instructions

1. In a large bowl, cover the lentils with boiling water and allow to sit for 15 minutes. This helps soften the lentils and reduce cooking time. After 15 minutes, drain the lentils thoroughly.
2. In a large stockpot (7 qt.) on medium heat, sauté the diced onions, leeks, and optional red bell pepper, and minced garlic with the olive oil, salt, pepper, thyme, and cumin for 20 minutes, or until the vegetables are translucent and very tender. Stir frequently to prevent burning, and adjust the heat if necessary.
3. Add the diced celery and carrots to the pot and sauté for 10 more minutes, stirring occasionally, until they begin to soften slightly.
4. Pour in the vegetable stock, then stir in the tomato paste. Ensure the tomato paste is fully incorporated into the stock.
5. Add the drained lentils and bay leaf to the pot.
6. Cover the pot and bring the mixture to a boil.
7. Once boiling, reduce the heat to low and simmer uncovered for 1 hour, or a little longer to taste, until the lentils are cooked through and tender. Stir occasionally to prevent sticking.
8. Check the seasonings and adjust as needed. Add more salt, pepper, or cumin to your liking.
9. Stir in the red wine vinegar (or red wine) just before serving. This adds a touch of acidity that brightens the flavors.
10. Serve the soup hot, drizzled with a little olive oil and sprinkled with freshly grated Parmesan cheese (if desired).

Expert Tips & Tricks

• Lentil Selection: French green lentils (Puy lentils) hold their shape better during cooking than red lentils, making them ideal for this soup. Brown lentils are also a good option.
• Vegetable Prep: Dicing the vegetables into small, uniform pieces ensures they cook evenly and create a pleasing texture in the soup.
• Sautéing Technique: Don’t rush the sautéing process. Allowing the onions, leeks, and garlic to cook slowly and become very tender is key to developing a rich, flavorful base for the soup.
• Stock Quality: Using a high-quality vegetable stock will significantly enhance the flavor of the soup. Homemade stock is best, but a good store-bought variety will also work.
• Thickening the Soup: If you prefer a thicker soup, you can use an immersion blender to partially blend a portion of the soup. Be careful not to over-blend, as you want to maintain some texture.
• Flavor Boosters: A squeeze of lemon juice in addition to, or instead of, the red wine vinegar, will also add brightness.

Serving & Storage Suggestions

Serve this lentil vegetable soup hot as a hearty and satisfying meal. It pairs well with crusty bread, a simple green salad, or even popovers, as Ina suggests!

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. For longer storage, freeze the soup in quart containers for up to 2-3 months. Thaw the soup in the refrigerator overnight before reheating.

To reheat, gently warm the soup on the stovetop over medium heat, stirring occasionally, until heated through. You can also reheat it in the microwave. If the soup has thickened too much during storage, add a little vegetable stock or water to thin it out.

• Different Vegetables: Feel free to experiment with other vegetables, such as diced zucchini, butternut squash, or sweet potatoes.

• Herbs: Fresh rosemary or oregano can be used in place of, or in addition to, the thyme.
• Soy Chorizo: While the original introduction suggested it, please be aware that this would make it non-vegetarian.

FAQs (Frequently Asked Questions)

Q: Can I use canned lentils instead of dried lentils?
A: While dried lentils are recommended for the best texture and flavor, you can use canned lentils in a pinch. Rinse and drain the canned lentils before adding them to the soup, and reduce the simmering time accordingly.

Q: How can I make this soup ahead of time?
A: This soup is even better the next day! Prepare the soup completely, let it cool, and store it in the refrigerator for up to 2-3 days. Reheat gently on the stovetop before serving.

Q: Is it necessary to soak the lentils before cooking?
A: Soaking the lentils is not strictly necessary, but it can help to reduce the cooking time and make them more digestible. If you have the time, a 15-minute soak in boiling water is beneficial.

Q: Can I freeze this lentil soup?
A: Yes, this soup freezes beautifully. Allow the soup to cool completely before transferring it to freezer-safe containers. Thaw overnight in the refrigerator before reheating.

Q: Can I use a different type of stock?
A: While vegetable stock is recommended to keep it vegetarian, you can use chicken stock if you prefer.
