When I first became a vegetarian, stuffed peppers were one of my favorite things to make. They're easy to prep ahead of time for busy weeknight meals and are usually packed full of plant protein and fiber from different legumes and grains.

I've tried several different versions over the years, like these Mediterranean Quinoa Stuffed Peppers which I love, but with winter upon us I wanted to make something that would provide a little more warmth. Something you could eat curled up in your sweatpants with a blanket on the couch. Because that's pretty much all I feel like doing this time of year!


The beauty of this stuffed pepper soup is that it's made in one pot and you don't have to worry about taking the time to stuff each individual pepper. I went for more of a classic version using brown rice and lentils for protein alongside tomatoes, onion and dried herbs.

It's as simple as sauteing the onion with the garlic and bell peppers, adding the lentils along with dried oregano and thyme, canned tomatoes, tomato sauce and vegetable broth, then letting everything boil for about 35 minutes or so.

While that's cooking you can clean up and prepare the rice. Trader Joe's sells packages of frozen organic brown rice which work perfectly for this recipe. Just three minutes in the microwave and it's ready to serve. You can't beat that with a stick!


Side note: I recommend adding a small amount of rice to each individual bowl as you eat it because adding it to the pot with the whole batch of soup will cause it to thicken, leaving barely any broth behind. Then it will be more like a stew than a soup, which isn't really what we're going for.

This stuffed pepper soup is the perfect meal for this time of year. It's easy to make, loaded with protein and fiber, and the vitamins and antioxidants will keep your immune system strong to help ward of winter sickness. Cheers to good food and a happy healthy new year!

Ingredients

  • 1 cup uncooked brown lentils rinsed
  • 1 tablespoon olive oil
  • 1 yellow onion diced
  • 3 cloves garlic
  • 1 red bell pepper cored and diced
  • 1 green bell pepper cored and diced
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • 1 15-ounce can diced fire roasted tomatoes
  • 1 15-ounce can tomato sauce
  • 4 cups vegetable broth
  • 2 cups water
  • 10 ounces cooked brown rice optional
  • Fresh parsley for serving optional

US Customary - Metric

Instructions

  • In a large pot, warm the olive oil over medium-low heat. Add the diced onion, sprinkle with a pinch of salt and pepper, and cook for about 3 minutes, until translucent.

  • Next, add the garlic, bell peppers and dried herbs, and continue to cook for 5 more minutes. Pour in the can of diced tomatoes with their juices, tomato sauce, vegetable broth, water, and lentils, and stir everything together. Turn the heat to high to bring to a boil then reduce it to medium and cook for about 35 minutes, or until the lentils are tender.

  • Serve the soup warm with fresh parsley and add brown rice as desired on top of the soup.

Notes

Note that if you add all of the rice to the pot with the soup, the starches will cause it to thicken, almost like a stew. I recommend adding it as needed as you eat. Store leftovers in an airtight container in the refrigerator for up to 3 days.

    The share icons cover too much of the left hand side of the page on all my devices.. Especially my phone.
    It's very bothersome.

    This soup is great. No changes other than I reduced the broth to 2 cups, added a splash of wine and used red lentils because that's all I had. More chili-like with less water, but delicious.

    You know, one of my favorite soups used to be a stuffed bell pepper soup with ground turkey and I've missed it since I became a vegetarian in March. I never even THOUGHT to use lentils. How silly of me! Can't wait to make this!! 🙂

    Mmm . . . I love lentils! I am making this soon. (Glad I have some leftover brown rice in the fridge!)

    This turned out delicious! Even my carnivore husband loves it. For the rice, I made lime-cilantro rice (add a handful of chopped cilantro, lime juice and a little salt). I think adding the rice afterwards is a great touch! Will definitely make again!

    This is so good!! I've been planning for one lentil meal each week and it's been hit or miss if we loved them. Safe to say this was a huge hit! So savoury and flavourful - the leftovers were even better!!

    Do you think this would freeze well? Looking for some good easy freezer food for a vegan friend who recently had a baby 🙂

      Hi Megan! Yes, I think this would freeze well. I would just let it cool to room temperature before freezing it. 🙂

    Oh Sarah this looks deeeelish! If I were to take out the brown rice what could I replace it with? Just more lentils? A veggie? And how much would you suggest adding?

    This was seriously delicious! It was perfect for lunch too. I blended mine because I don't like big chunks of tomato, personal preference. I would definitely make this again. Hearty, and crowd pleasing - and good for the soul.

    I'm sure the question has been asked so sorry but lastly. Do we cover at the end while it's cooking for the 35 min or leave uncovered?

FAQs

Do I have to cook lentils before adding to soup? ›

Do you cook lentils before adding to soup? Nope! Dried lentils cook in 35 minutes in the soup, and there's no need to soak them either!

Why is my lentil soup too thick? ›

If the soup seems too thick add 1 more cup of vegetable stock (or water). Taste test and adjust seasonings as needed. Using an immersion blender or regular blender puree half of the soup (don't skip this part...the texture of smooth/chunky is the best!) Keep the soup on low heat until ready to serve.

Can you overcook lentil soup? ›

Yes, you can overcook lentils; they will become mushy. Much depends on the type of lentil you're using. Some cook quicker and hold their shape better than others. To avoid overcooking them, always follow the cooking directions in your recipe and use the type of lentils called for in the ingredient list.

Do lentils soak up broth? ›

Lentils aren't rice—they don't need to absorb every last drop of cooking liquid. They're more like pasta: best cooked in an abundance of water or stock. Bring your liquid up to a boil, add your lentils, then turn down your heat to a simmer for at least 25-30 minutes.

What happens if you don't soak lentils before cooking? ›

Well, as healthy as they are, lentils are also known to cause some tummy issues like bloating and flatulence to be more specific. The presence of anti-nutrient compounds in lentils is the culprit behind gas or flatulence. The good news is that anti-nutrient in lentils can be easily deactivated by soaking them in water.

Should lentils be soaked for soup? ›

The other good news: Lentils don't need to soak as beans do (though you do need to sort and rinse them before cooking). Different types of lentils cook in different amounts of time. Red lentils are the fastest cooking and they dissolve as they cook and make for a smooth soup.

What happens if you eat too much lentil soup? ›

If you eat fiber-rich lentils regularly, they can cause gas and bloating. If you are sensitive to fermentable oligosaccharides, disaccharides, monosaccharides and polyol (FODMAP) foods, lentils can cause discomfort, as well as bloating and gas in the colon.

What can I use to thicken lentil soup? ›

You can also use flour or cornflour to thicken a soup. Put a tablespoon of either into a small bowl and stir in 2-3 tbsp of the soup until you have a smooth mixture. Stir this back into the soup and bring it to a simmer.

What is the foam on top of lentil soup? ›

When cooking dal why does it create foam on the top? The grey foam that forms on top of a pan of lentils is caused by a substance in the beans called saponins. This substance lathers up in the water, just like soap – in fact, the word 'saponins' actually comes from the Latin word for soap, 'sap!

What makes lentils taste better? ›

If you don't have stock on hand, add onion, carrots, celery, garlic cloves and/or herbs to the pot. All of these are mild flavors that can jump in any direction depending on how you're going to use the cooked lentils.

What color lentils are best for soup? ›

And while you could make it with any kind of lentil—brown, green, red, you name it—I think it's the most delicious version of itself when made with French green lentils. IMHO, they're just about the best kind of lentils for soup that exist.

What happens if you don't rinse lentils? ›

While not rinsing lentils may not pose an immediate safety risk, it is generally recommended to rinse them before cooking to ensure a cleaner and more enjoyable meal. If you have already cooked the soup, you can still enjoy it, but be mindful of any potential debris or grit that may be present.

Why do you add vinegar to lentil soup? ›

It may sound a bit strange and unusual for some, but vinegar is a common ingredient in some soup recipes, and there is a good reason for it. If you think about it, vinegar is really a flavor-enhancer (umami). That's why it is so often used in cooking, sauces, and salad dressings. The same is true with soups.

How to tell if lentils are done? ›

Honestly, the best way to tell if lentils are done are to taste them. They should be tender to the bite, with some varieties of lentils being a bit more firm and others more soft. That said, if you would like your lentils to be softer, just simmer them a few minutes longer until they reaches your desired consistency.

Do you cook lentils covered or uncovered? ›

Bring to a boil, cover tightly, reduce heat and simmer until they are tender. For whole lentils, cook time is typically 15-20 minutes. For split red lentils, cook time is typically only about 5-7 minutes. Be sure to season with salt after cooking – if salt is added before, the lentils will become tough.

What happens if you don't cook lentils? ›

Raw lentils, like other legumes, contain a protein called lectin that binds to your digestive tract and can result in several toxic reactions, such as diarrhea and vomiting. Lentils are a nutritious food choice, low in fat and high in protein and fiber.

Do I need to pre-cook lentils? ›

Nope! Unlike lots of other dried pulses (such as some dried beans), lentils don't need to be soaked before cooking. This means they're really quick and easy to use – you can decide you want to cook lentils when you're already ready to start cooking, and they can be ready to eat not long after.

Do you cook canned or dry lentils? ›

Preparation, Cooking, and Storage

While canned are good for ready-to-eat uses such as a quick salad or side dish, the dried version works well for soups and stews, salads, and sides. A bag of dried lentils can really last forever, but they are best used within a year of purchase (or by the date printed on the package).

Why do lentils need to be cooked? ›

Can You Eat Lentils Raw? The short answer? No. Like other legumes, raw lentils contain a type of protein called lectin that, unlike other proteins, binds to carbohydrates and your body can't digest them.
