Why you need this protein lentil soup
It's November which means it is officially SOUP SEASON. Despite being a summer girl I honestly think soup season may be one o the best seasons there is. There is just something super comforting about coming home on a cold day to a warm bowl of soup.
However I've never really been able to call soup a meal. Sure it taste great but it never leaves me feeling full for more than an hour. Which is why I have been loving this High protein lentil soup recipe recently.
Here are three reasons why I love it:
- It's a dietitian approved balanced meal- Made with lentils for protein and fibre, and lots of veggies (including leafy greens) this is a soup that will power you through your day. PLUS there's a secret ingredient for even more protein!
- It's EASY- Soup has always seemed intimidating to me. I don't know what it is but I feel like there were always just SO many ingredients. But not with this soup! All you need are a few simple ingredients and a pot and you are good to go!
- Its perfect for meal prep! - With only 15 minutes of hands on prep time needed this is the perfect soup to prep for a busy week (plus it freezes wonderfully)!
Ingredients needed for the lentil kale soup recipe
Lentils- The star of this protein lentil soup! I LOVE adding lentils to meals for an easy boost of plant based protein and fibre (plus they just taste so good). or this recipe I use dry red lentils (don't use canned or your soup will be too soggy)!
Vegetables- Celery, onions and carrots are needed for the base of this soup (called a mirepoix) which is the key ingredient in any good soup recipe! We also add LOTS of leafy greens- so grab your curly kale or spinach!
Bone broth- Recently I have been loving adding bone broth to my soups for an extra dose of protein (plus glycogen and collagen for my joints). However don't worry if you don't have nay on hand- any vegetable or chicken broth will work!
Water- To help thin the soup a little!
Tomato sauce- Any tomato sauce will do. I personally love this one as I find it has the most authentic flavour (and no added sugar). However use whatever you have on hand. This is supposed to be an easy recipe so don't over complicate it!
Spices- All you need is ground cumin and crushed garlic to make this soup taste AMAZING (plus a little salt and black pepper if you desire)!
How to make lentil soup high protein?
This soup not only tastes amazing but it also is incredibly easy to make. Grab your ingredients and a large pot and let's get started making the BEST lentil kale soup.
Step one: Make your mirepoix. Mirepoix is the secret to ALL good soups. It's a french base from the aromatic vegetables of carrots, celery and onion that are diced and sauteed in olive oil until soft and fragrant. It helps add flavour to ANY soup and is a key ingredient in our high protein lentil soup! So over medium heat add your olive oil to your pot. Once hot add in your onion, celery and carrots and sautée until soft (about 5 minutes). Add in your garlic and saute for another minute.
Step two: Simmering time- add your bone broth, ground cumin and lentils, cover and allow to simmer for about 25 minutes.
Step three: the final product- After 25 minutes add in your tomato sauce, and stir in your leafy greens. Add water to thin until it reaches the desired consistency ( it is a thicker soup) and season with salt and pepper!
Voila your bone broth vegetable soup is DONE and ready to be enjoyed!
Frequently asked questions
How do I store this high protein lentil soup?
This soup stores well in an air tight Tupperware container in the fridge for up to 5 days or in the freezer for up to 3 months!
Recently I have been LOVING these souper cubes to store soups in the freezer for the perfectly portioned meals!
Is this soup enough for a meal on it's own?
It really depends on each individual and their hunger levels. For me I like pairing my soup with some whole grain crackers (like Triscuits or Ryvita) or a small salad just to help keep me feeling satisfied longer.
However this soup does contain protein, fibre and vegetables so it could work as a meal as well!
What are lentils and how is this a high protein lentil recipe?
Lentils are a type of legume that on their own are full of both protein and fibre. On average ½ a cup of cooked lentils contains 12g of protein and 9 g of fibre!
To increase the protein content of this soup (and help make it a little more filling) I swapped out the typical broth for bone broth making a bone broth vegetable soup!
Can I swap the broth in this bone broth vegetable soup?
YES! You can easily just swap out the bone broth for a vegetable or chicken broth if you don't have any bone broth on hand! Nutrition tip: I personally always like to choose a lower sodium broth and customize the salt to my taste prefrance after!
Is this a vegetarian recipe?
Yes and no! As bone broth is typically made from chicken if you decide to use bone broth in this lentil kale soup then it will not be vegetarian or vegan!
However you can easily swap out the bone broth for a vegetable broth to make this protein lentil soup both vegan and vegetarian friendly!
Organika also offers a vegetable based broth that also has protein!
