Step‑by‑Step Instructions for Hearty Roasted Garlic Vegetable Stew with Red Lentils & Tomatoes
Step 1: Preheat the Oven
Start by preheating your oven to 425°F (220°C). While the oven heats up, line a large baking tray with parchment paper to prevent sticking. This step is crucial for achieving the perfect roasted flavor in your vegetables, which will be the star of your roasted garlic vegetable stew.
Step 2: Prepare the Vegetables
In a large mixing bowl, toss the cauliflower, diced sweet potatoes, and chopped red bell peppers with a generous drizzle of olive oil. Ensure each piece is evenly coated, which will help them caramelize beautifully during roasting. Spread the vegetables out in a single layer on your prepared baking tray, creating space between them for even cooking.
Step 3: Roast the Garlic
Slice the top off the head of garlic and drizzle it with olive oil. Wrap the garlic in aluminum foil and place it on the baking tray alongside the vegetables. Roast everything in the preheated oven for 30-40 minutes, tossing the vegetables every 15 minutes. Keep a close eye on the garlic, checking it around the 25-minute mark to prevent burning.
Step 4: Sauté the Aromatics
While the vegetables are roasting, heat a splash of olive oil in a large pot over medium heat. Add the diced onion and minced garlic, sautéing for about 3-4 minutes until the onion is soft and translucent. This fragrant base will infuse your hearty roasted garlic vegetable stew with essential flavors as it begins to come together.
Step 5: Combine Ingredients
Once the onions are softened, add dried oregano, thyme, basil, canned diced tomatoes, vegetable broth, and red lentils to the pot. Stir well to combine and bring the mixture to a boil. After it reaches a boil, reduce the heat to low and let it simmer for 10 minutes, stirring occasionally until the lentils are tender.
Step 6: Blend for Richness
Remove the roasted garlic from the oven and allow it to cool slightly. Squeeze the softened garlic cloves into a blender, adding tomato paste, balsamic vinegar, and half of the roasted vegetables. Pour in 2 cups of the simmering soup and blend until smooth. This step enhances the flavor of your roasted garlic vegetable stew, giving it a deliciously creamy texture.
Step 7: Final Touches
Return the blended mixture to the pot and stir in the remaining roasted vegetables. Add the torn kale and continue to cook on low heat just until the kale wilts, approximately 1 minute. This final step brings vibrant color and nutrition to your hearty roasted garlic vegetable stew, making it a delightful dish ready to be served warm.
