Step‑by‑Step Instructions for Roasted Garlic Vegetable Stew with Red Lentils & Tomatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). This high temperature is crucial for roasting our vegetables effectively, allowing them to caramelize beautifully and develop deeper flavors.
Step 2: Prepare the Vegetables
In a large bowl, toss the cauliflower, sweet potato, and red bell peppers with a generous drizzle of olive oil, ensuring even coating. Spread the vegetables in a single layer on a lined baking tray, which will help with easy cleanup.
Step 3: Roast the Garlic
Take a whole bulb of garlic, slice off the top, drizzle with olive oil, and wrap it in foil. Place this wrapped garlic bulb on the tray with your vegetables and roast everything in the oven for 30-40 minutes, tossing the veggies halfway through for even cooking.
Step 4: Sauté the Base
While the vegetables and garlic are roasting, heat a tablespoon of olive oil in a large pot over medium heat. Add the diced onion and minced garlic from the roasted bulb, sautéing for about 3-4 minutes until they become fragrant and soft, creating a flavorful base for your stew.
Step 5: Combine Ingredients
Once the onion and garlic are golden, stir in the dried oregano, thyme, and basil, letting the herbs bloom for about a minute. Add in the canned fire-roasted diced tomatoes, vegetable broth, and red lentils, bringing the mixture to a boil before reducing the heat to low. Cover and let it simmer for roughly 10 minutes.
Step 6: Blend the Mixture
Once your garlic is roasted and the stew has simmered, carefully squeeze the garlic cloves into a blender, discarding the skins. Add a ladle of the stew and a handful of the roasted vegetables, blending until silky smooth, then return this blend to the pot for a creamy texture in your Roasted Garlic Vegetable Stew.
Step 7: Finish the Stew
Finally, stir the remaining roasted vegetables and chopped kale into the pot, cooking until the kale wilts, which will take about 2-3 minutes. Season with salt and pepper to taste, and let this cozy Roasted Garlic Vegetable Stew with Red Lentils & Tomatoes warm through before serving hot.
