Red Lentil Soup Ingredients
While this spiced lentil soup has a long-ish ingredient list, they all work together to produce a tasty result. Trust me, you won’t want to miss out on these rawkin’ fresh vegetables and vibrant spices.
- Coconut Oil: My favorite healthy fat to help sauté a few of the ingredients.
- Yellow Onions: My go-to onion for its buttery, mild flavor.
- Celery Stalks: An often hidden, yet necessary ingredient to make any soup a success. Pro tip: use the leafy ends of the celery in the soup if you can! They bring even more flavor.
- Garlic: I always mince fresh garlic for the most nutrition. Garlic is a powerful health booster.
- Fresh Ginger Root: This anti-inflammatory root packs a powerful punch, so a little goes a long way!
- Spices: I use a blend of cumin, turmeric and red pepper flakes to add warmth, earthiness and just a bit of heat.
- Fire-Roasted Tomatoes: If you like depth that roasted brings, then these are a no-brainer! You can use regular diced tomatoes, too.
- Vegetable Stock: Homemade vegetable stock or store-bought, look for a one with real ingredients.
- Red Lentils: These have a less-earthy flavor than green lentils do. Red lentils also get softer during cooking, which is what I wanted for this soup. Look for dried lentils next to dried beans, or in the soup aisle.
- Spinach: I always add leafy green vegetables— our health is our wealth, right?
How to Make Red Lentil Soup
This soup does have a few more components than some, yet it’s 100% worth it at first bite. Here’s how I make my Red Lentil Soup:
Sauté the onion and celery in coconut oil (or the oil of your choice). This releases the flavors and adds a lovely warmth to your final product.
Sauté the garlic and ginger, stirring constantly so the garlic doesn’t burn (this can happen quickly!). Use fresh minced garlic for the best results.
Add spices and tomatoes, namely turmeric, cumin and fire-roasted tomatoes. Stir quickly to combine so that the spices don’t stick to the bottom.
Add vegetable stock and lentils and give the soup a few stirs to cover the lentils. Now all you need to do is allow the soup to simmer until the lentils are soft (no crunch!).
Add spinach and lemon juice once the soup is ready. Lemon juice is a game-changer so don’t omit!
Feel free to taste the spiced lentil soup and add in a bit of salt and pepper, or just let people add it to their own bowls after serving.
Red Lentil Soup Tips
- My number one tip for the best-tasting soup all the time is this sauté the aromatic ingredients. Whether you are slow-cooking your soup or just simmering on the stove top, taking a few minutes to sauté a few of the veggies first opens them up nicely. I want my soup to be as flavorful as possible and this is the way to do it.
- My second tip is to make extra! Whether you’re feeding one person or a family of five, make sure to have a few extra servings when you’re finished. This way you can freeze or refrigerate them to enjoy later in the week for quick lunches or dinners. No need to chop all that produce more than once.
- Finally, use what you have on hand. Soup often contains several ingredients, yet they can easily be swapped for something that’s easier for you to find or less expensive to purchase in your town. Living in Florida gives me access to a wide variety of produce that I know isn’t available all over the United States. If you ever need help with a swap, just drop a comment below and let me help!

Notes
- Crockpot: Put everything in the slow cooker and cook on low 6 hours or on high 2 1/2 hours. Check earlier in case lentils cook extra fast— you don’t want them too mushy.
- Swap ground turmeric with fresh turmeric root for even more anti-inflammatory benefits.
- Swap fresh ginger root with 1/8 tsp ground ginger, though this will eliminate some of the nutrition found in fresh ginger.
- Omit the red pepper flakes and use regular diced tomatoes for a less spicy result.

Mine is! I use as many fresh, whole food ingredients as I can so that this soup nourishes and helps boost your immune system during cooler weather.
Not in my soup. I do rinse my lentils before adding them to the soup pot, but they will soften nicely inside the simmering stock without the need to soak beforehand.
You can, but the texture will change. Brown or green lentils take longer to cook and hold their shape, so the soup won’t be as creamy. Stick with red lentils for that smooth, hearty consistency.
It will keep for up to 4–5 days in an airtight container in the fridge. It also freezes well—just let it cool completely, portion into freezer-safe containers, and reheat as needed.
Beautiful soup! Surprised it tasted milder than expected, which was great for my daughter! I added salt. Definitely a keeper.
Okay to freeze any leftovers?
Yes— this soups freezes beautifully! So glad you enjoyed it Susan.
Very tasty – great way to use lentils!
100%. Thanks for the feedback, Sarah.

Thanks so much, Shosh!
Mostly followed recipe, except used olive oil, half the garlic ( 8 cloves seemed like too much), and forgot the lemon juice. Was very good as is, but since we were having pork fingers for supper, I added mine to the soup and skipped the fries. Good to the last bite and kept me full the rest of the night.
Way to make it work for you, Janet.
