Key Ingredients for Hearty Lentil Vegetable Soup
- Brown or Green Lentils: One cup of rinsed lentils provides the soup with substance and a tender, slightly firm texture. Brown and green varieties generally hold their shape better than red lentils.
- Onion, Carrots, and Celery: This combination creates a savory vegetable base. Dice the vegetables into similar-sized pieces so they soften evenly during cooking.
- Garlic and Tomato Paste: Garlic adds aroma, while tomato paste deepens the savory flavor. Cooking the tomato paste briefly before adding the liquids helps develop its taste.
- Diced Tomatoes and Vegetable Broth: Canned tomatoes contribute acidity and texture, while low-sodium vegetable broth provides the liquid base without making the soup overly salty.
- Dried Herbs and Spices: Thyme, oregano, and cumin give the soup an earthy, aromatic character. Measuring the spices carefully keeps their flavors balanced.
Chef’s Tip: Let the tomato paste cook with the garlic and seasonings for about a minute before adding the broth. This quick step develops a deeper savory base without adding extra ingredients.

Sticky Sesame Chickpeas Broccoli Recipe
Equipment
- Large mixing bowl
- Mixing spoon or spatula
- Measuring cups
- Measuring spoons
- Colander or clean kitchen towel
- Airtight container
Ingredients
- 1 package 10 ounces frozen chopped spinach, thawed
- 1 container 16 ounces sour cream
- 1 cup mayonnaise
- 1 packet 1.4 ounces Knorr Vegetable Recipe Mix
- 1 can 8 ounces water chestnuts, drained and finely chopped, optional
- 3 green onions thinly sliced, optional
Instructions
- Remove the frozen spinach from its packaging and thaw it completely. You can thaw it overnight in the refrigerator or use the microwave according to the package directions. Once thawed, place the spinach in a colander and press out as much liquid as possible. For the best texture, squeeze it firmly in a clean kitchen towel. Excess moisture can make the dip watery.

- Add the sour cream and mayonnaise to a large mixing bowl. Stir until the mixture is smooth and evenly combined. These ingredients create the creamy base that helps the vegetable seasoning blend distribute throughout the dip.

- Sprinkle the Knorr Vegetable Recipe Mix into the bowl and stir well. Add the thoroughly drained spinach, then mix until it is evenly distributed. If using water chestnuts and green onions, fold them in now for extra crunch and a fresh onion flavor.

- Cover the bowl or transfer the mixture to an airtight container. Refrigerate for at least 2 hours before serving. Chilling allows the seasoning to hydrate and the flavors to blend. For a stronger flavor, prepare the dip the night before.

- Before serving, stir the dip well and taste it. The seasoning mix usually provides enough salt, so additional salt may not be necessary. Transfer the dip to a serving bowl and serve chilled with crackers, sliced vegetables, pita chips, or bread.

Notes
- Drain the spinach thoroughly: This is the most important step for a thick, creamy dip. Too much liquid can make the mixture runny.
- Use the correct seasoning mix: Knorr Vegetable Recipe Mix is the classic choice for this recipe. Knorr products and packet sizes can vary by country, so check the package and adjust as needed.
- Skip the water chestnuts if preferred: They add a crisp texture, but the dip is still delicious without them.
- Adjust the consistency: For a thicker dip, use a little less mayonnaise. For a lighter texture, replace some of the mayonnaise with additional sour cream or plain Greek yogurt.
- Make it ahead: This dip can be prepared up to 24 hours before serving. Keep it covered and refrigerated until ready to serve.

Frequently Asked Questions
- Do lentils need to be soaked before making this soup?
No. Brown and green lentils generally do not need soaking for this recipe. Rinse them under cold water and remove any small debris before cooking. - How do I know when lentils are fully cooked?
Taste a few lentils after the recommended simmering time. They should be tender throughout while retaining their shape, without a hard or chalky center. - Can I use water instead of vegetable broth?
Yes. Water can replace the vegetable broth, but the soup may have a milder flavor. You may need to adjust the herbs, spices, and salt to compensate. - Why does this recipe include a potato?
The diced potato adds body and a soft texture to the broth. As it cooks, some of its starch helps give the soup a fuller consistency. - Can I cook this soup in a pressure cooker?
Yes, although the cooking method and timing will differ. Follow your pressure cooker’s instructions for dried lentils and account for the time needed for pressure to build and release. - What is the purpose of adding lemon juice at the end?
Lemon juice provides acidity that balances the earthy lentils and savory vegetables. Adding it near the end preserves its fresh, bright taste. - Can I make this soup without tomato paste?
Yes. You can omit the tomato paste, although the broth will have a slightly less concentrated tomato flavor. The diced tomatoes will still contribute acidity and tomato flavor to the soup.
