How to Make high protein lentil and kale soup with roasted root vegetables and herbs

1
Preheat the Oven:

Preheat the oven to 425°F (220°C). This will be used to roast the root vegetables.

2
Chop the Vegetables:

Chop the carrots, celery, and onions into bite-sized pieces. This will help them roast evenly in the oven.

3
Roast the Vegetables:

Toss the chopped vegetables with olive oil, salt, and pepper, and spread them out on a baking sheet. Roast in the preheated oven for 20-25 minutes, or until they're tender and lightly browned.

4
Saute the Aromatics:

In a large pot, heat some olive oil over medium heat. Add the chopped onions and cook until they're translucent, about 5 minutes. Add the minced garlic and cook for another minute, until fragrant.

5
Add the Lentils and Broth:

Add the lentils, chicken or vegetable broth, and diced tomatoes to the pot. Bring the mixture to a boil, then reduce the heat to low and simmer for 20-25 minutes, or until the lentils are tender.

6
Add the Kale and Herbs:

Stir in the chopped kale and cook until it's wilted, about 2-3 minutes. Add the chopped fresh herbs, such as thyme and rosemary, and season with salt and pepper to taste.

7
Blend the Soup:

Use an immersion blender to puree the soup until it's smooth, or leave it chunky if you prefer. Taste and adjust the seasoning as needed.

8
Serve and Enjoy:

Ladle the soup into bowls and serve hot, garnished with additional fresh herbs if desired. You can also serve with a side of crusty bread or a green salad for a filling and satisfying meal.

Tips for Perfect Results

Use Fresh and High-Quality Ingredients:

The quality of your ingredients can make a big difference in the flavor and texture of your soup. Choose fresh and organic options whenever possible.

Don't Overcook the Lentils:

Lentils can become mushy and unappetizing if they're overcooked. Cook them until they're tender, but still retain some texture.

Add the Kale at the Right Time:

Adding the kale too early can cause it to become overcooked and lose its nutrients. Add it towards the end of cooking time, so it retains its texture and flavor.

Experiment with Different Herbs and Spices:

Feel free to experiment with different herbs and spices to find the combination that you enjoy the most. You can also add other ingredients, such as diced bell peppers or chopped mushrooms, to add more flavor and texture.

Make it a Meal Prep Option:

This soup is perfect for meal prep, as it can be made in large batches and refrigerated or frozen for later use. Simply reheat and serve when you need a quick and easy meal.

Serve with Crusty Bread or a Green Salad:

Serving the soup with crusty bread or a green salad can add more texture and flavor to the meal. You can also serve it with a side of roasted vegetables or a simple green salad for a filling and satisfying meal.

Freeze for Later:

This soup can be frozen for up to 3 months, making it a great option for meal prep or for when you need a quick and easy meal. Simply thaw and reheat when you're ready to serve.

Add Some Heat:

If you like a little heat in your soup, you can add some diced jalapenos or red pepper flakes to give it a spicy kick.

Common Mistakes to Avoid

  • Overcooking the Lentils:

    Fix: Cook the lentils until they're tender, but still retain some texture. Check the package instructions for specific cooking times.

  • Not Adding Enough Liquid:

    Fix: Make sure to add enough liquid to the pot, as the lentils will absorb a lot of it during cooking. You can always add more liquid if the soup becomes too thick.

  • Not Seasoning Enough:

    Fix: Don't be afraid to add more salt, pepper, and other seasonings to taste. You can always adjust the seasoning to your liking.

  • Not Using Fresh Ingredients:

    Fix: Choose fresh and organic ingredients whenever possible. This will make a big difference in the flavor and texture of your soup.

Variations & Substitutions

Spicy Version:

Add some diced jalapenos or red pepper flakes to give the soup a spicy kick.

Vegan Version:

Substitute the chicken broth with a vegan broth and use vegan-friendly seasonings.

Gluten-Free Version:

Use gluten-free broth and be mindful of any gluten-containing ingredients.

Low-Sodium Version:

Use low-sodium broth and seasonings to reduce the sodium content of the soup.

Add Some Smokiness:

Add some smoked paprika or liquid smoke to give the soup a smoky flavor.

Add Some Creaminess:

Add some coconut cream or heavy cream to give the soup a creamy texture.

Storage & Make-Ahead

Room Temp:

The soup can be stored at room temperature for up to 2 hours. After that, it's best to refrigerate or freeze it.
