    Vegan Stir-fried Veggies & Whole Red Lentils with Ketchup-Based Sauce

    Updated: May 14, 2025 · Published: Oct 14, 2024 by Vegin Vegan Vegun! · This post may contain affiliate links · 1 Comment

    Here's a simple vegan recipe for whole red lentils stir-fried with ketchup & onion koji (Homemade vegan consomme). If you are a fan of omurice (オムライス / Japanese omelet rice) and ketchup, I highly recommend giving this recipe a try.

    What makes this recipe special is that it's loaded with colorful summer veggies. It doesn't use any spices, so it's seasoned in a way that even kids can enjoy. You'll definitely want to use corn and carrots because they'll make the dish even sweeter. That way, the bitterness of the green peppers you add as an accent won't be as noticeable.

    It's a tasty dish with a nice mix of the five basic tastes. The ketchup flavor also evokes nostalgia, which makes me love the dish so much.

    If you're looking for more recipes using whole red lentils, I also recommend my Vegan Bolognese. It's also tomato-based, but cooking lentils with bay leaves give it a more sophisticated flavor.

    They're both balanced nutrition-wise, with lots of vegetables and protein. Also it's easy enough for anyone to try, so give them both a try!

    🧃Ingredients

    Bell peppers, carrots, onions, corn, green beans, ketchup, onion koji, boiled skinned lentils, salt

    Main Ingredients

    • Vegetables: I use green beans, onions, carrots, boiled corn, and green peppers. You can omit the onions, but I would prefer that you prepare and include all of the other vegetables. Especially the green peppers and corn, which I absolutely want you to add! They go well with beans and ketchup, providing a nice contrast in flavor.
    • Whole red lentils: Use cooked whole red lentils(amazon). I use a pressure cooker to boil them. Rinse 200 g of lentils thoroughly and place them in the cooker with 800 ml of water. After approximately 8 minutes of pressure building, remove the cooker from the heat. If you cook them for too long, they will lose their shape and become soupy. If you've never cooked lentils in a pressure cooker before, start with 5 minutes of pressure cooking and see how it goes. When the pressure has decreased, open the lid and check if the lentils are tender.

    Seasoning

    • Onion Koji: The recipe's umami component is onion koji. It Koji is a versatile, additive-free seasoning that can be used instead of consomme. I strongly advise keeping this wonderful ingredient in your refrigerator since it's useful for vegan cooking. The recipe is available here.
    • Ketchup: This is the most important seasoning in the recipe. When combined with onion koji, it creates a delicious ketchup stir-fry.
    • Salt: Slow-frying vegetables with salt enhances their flavor.
    • Oil: Just use a bit to sauté the vegetables.

    For exact amounts, please check the recipe card👇

    🥢Instructions

    Vegetables cut into cubes about the same size as corn kernels
    1. Preparation: First, cut the vegetables into cubes that are roughly the same size as the corn kernel.
    Stir-fry chopped vegetables in a yukihira pan.
    1. Stir-fry: Heat some oil in a pot, then add the chopped vegetables and a pinch of salt, stirring quickly. Afterwards, immediately cover the pot and cook over low heat for about 4 minutes. To avoid burning, occasionally open the lid and stir.
    seasonings are added to the stir-fried vegetables.
    1. Seasoning: After stir-frying, add the ketchup and onion koji and mix briefly.

    🍴Tools

    • kitchen knife
    • cutting board
    • sauce pan: I like to use a saucepan with a thick bottom because it makes the stir-fry process work better. If you don't have one, no problem! You can just use your own pan.
    • wooden spatula

    🫙Storage

    It's best to eat it right after it's made. The reason is that once it cools down, it loses its moderate thickening and tends to become dry. If you want to save it for later, just finish it with a looser thickness and put it in a food container in the fridge. If so, it's better to be eaten up within 2 to 3 days.

    💭Frequently Asked Questions

    Q: Do you have any tips for cooking Whole Red Lentils without using pressure cooker?

    In a big pot, add a lot of water and lentils and boil them until they're as firm as you like. It depends on the type of lentils, but for the Masoor Holdar I use, I always boil them for at least 20 minutes. It takes a while, so I usually use a pressure cooker, unless I really want to keep their shape.

    Notes

    How to Boil Lentils: It should weigh about 750 grams when it's done.
    1. Wash 200 grams of lentils well. Then, put them in a pressure cooker with 800 milliliters of water.
    2. After about 5-8 minutes of pressure cooking, remove it from the heat.
      * If you cook the beans for too long, they will lose their shape and turn into a mushy texture. If you've never cooked lentils in a pressure cooker before, start with 5 minutes of pressure cooking and see how it goes.
    3. When the pressure has decreased, open the lid and check with your finger how hard the beans are. If they are still crunchy, leave the lid open and cook them until they are soft enough for your taste.
    4. Use about half of the cooked beans for this recipe. You can use the rest of the lentils to make dishes like Vegan Bolognese.
