Step‑by‑Step Instructions for Roasted Garlic Vegetable Stew with Red Lentils & Tomatoes
Step 1: Roast the Vegetables
Preheat your oven to 425°F (220°C). In a large mixing bowl, toss together cauliflower florets, diced sweet potato, and sliced red bell peppers with olive oil until evenly coated. Spread the vegetables on a parchment-lined baking tray and prepare the garlic by wrapping it in foil with a drizzle of olive oil. Place both the vegetables and the wrapped garlic in the oven, roasting for about 30–40 minutes until the vegetables are tender and caramelized, flipping halfway through for even roasting.
Step 2: Sauté the Base
While the vegetables roast, heat a tablespoon of olive oil in a large pot over medium heat. Add chopped onion and minced garlic to the pot, stirring frequently for about 3–4 minutes until softened and fragrant. This flavorful base sets the stage for your Roasted Garlic Vegetable Stew with Red Lentils & Tomatoes, enhancing the overall richness as you progress through the recipe.
Step 3: Combine Ingredients
Once the onion and garlic are aromatic and translucent, add dried oregano, thyme, and basil to the pot, stirring for a minute to release their scents. Then, pour in the canned fire-roasted diced tomatoes and vegetable broth, followed by rinsed red lentils. Raise the heat to bring the mixture to a boil, then reduce it to a simmer, covering the pot and cooking for about 10 minutes until the lentils are tender and have absorbed the stew’s wonderful flavors.
Step 4: Blend the Garlic
After the vegetables finish roasting, squeeze the soft roasted garlic cloves from their skins into a blender. Along with the roasted garlic, add a few tablespoons of tomato paste and balsamic vinegar. Blend this mixture on high until it reaches a smooth consistency, creating a rich, creamy base that will enhance the texture and taste of your stew.
Step 5: Final Assembly
Return the blended garlic mixture to the pot along with the remaining roasted vegetables. Stir everything together to combine, then fold in the chopped kale. Cook gently over low heat for about 1 minute until the kale is just wilted but still vibrant, ensuring that all flavors from the Roasted Garlic Vegetable Stew with Red Lentils & Tomatoes meld beautifully into every spoonful.

Roasted Garlic Vegetable Stew with Red Lentils & Tomatoes Recipe FAQs
What type of vegetables should I use for optimal flavors?
Absolutely! The flavor of your stew can really shine with the right vegetables. I recommend using fresh cauliflower, sweet potatoes, and red bell peppers, as these roast beautifully to bring out natural sweetness. However, feel free to swap in broccoli, zucchini, or butternut squash based on your preferences or what you have on hand.
How should I store leftovers, and how long will they last?
For optimal freshness, store your Roasted Garlic Vegetable Stew in an airtight container in the fridge for up to 4 days. Just be sure to let it cool completely before sealing! It’s also freezer-friendly for up to 3 months—just remember to store it in freezer-safe containers or bags.
What’s the best way to freeze this stew?
Great question! To freeze, let your stew cool completely. Then, portion it into freezer-safe containers or bags—making sure to leave some room for expansion. Seal tightly and label with the date. When ready to enjoy, thaw in the refrigerator overnight and reheat gently on the stove, adding a splash of vegetable broth or water if it thickens up.
What can I do if my lentils aren’t cooking properly?
If you find that your lentils aren’t softening, it might be due to using older lentils that have lost moisture. Ensure to soak them overnight if they’re a firmer variety. For red lentils, they should cook relatively quickly, but if they’re still tough, simply give them a little more time on a low simmer with extra liquid, checking regularly!
Can I make this stew suitable for my dietary needs?
Very much so! This recipe is already vegan and packed with nutritious ingredients—perfect for a variety of diets. If you have allergies or dietary restrictions, avoid specific ingredients like garlic or certain vegetables and substitute them as needed. Just make sure to read labels for any pre-packaged items like broth or canned tomatoes to ensure they meet your needs.
How can I enhance the flavor even further?
I often recommend adding fresh herbs like cilantro or parsley just before serving. You can also incorporate spices like cumin or cinnamon for a warm twist. For a kick, add red pepper flakes during the cooking process. Experiment and enjoy creating the flavor profile that speaks to you!
