Step-by-step Preparation of Homemade Roasted Tomato Basil Soup
Making your own delicious homemade roasted tomato basil soup is a fulfilling endeavor that brings fresh flavors right to your kitchen. Follow these steps, and you’ll soon be savoring a warm bowl of comfort.
Preheat your oven
First things first, let's get that oven cooking! Preheat your oven to 400 degrees F. This temperature is perfect for roasting tomatoes, allowing their natural sweetness to emerge while creating a delightful caramelization. For easy cleanup, line a large baking sheet with parchment paper. It’s a simple step that can save you time and hassle later.
Roast the tomatoes and garlic
Once your oven is roaring hot, it’s time to prepare the star ingredients. Halve 3 pounds of roma or plum tomatoes and place them along with 8 cloves of peeled garlic on your lined baking sheet. Drizzle the mixture with 3 tablespoons of olive oil and season generously with freshly ground salt and pepper. Roast the tomatoes and garlic in the oven for 40-45 minutes, until they are beautifully caramelized and fragrant. This step not only enhances their flavor but also adds depth to your soup.
For tips on selecting the ripest tomatoes, consider choosing ones that have a deep red color and feel heavy for their size. Fresh herbs make a difference, too! Pair your tomatoes with a handful of fresh basil leaves for an added aromatic layer.
Caramelize the onions
While the tomatoes do their magic in the oven, let's multitask and caramelize the onions. In a large pot, heat ½ tablespoon of olive oil over medium heat. Add two thinly sliced yellow onions and stir them to coat with the oil. This process takes a bit of patience—stir occasionally, checking in every 5-10 minutes until they turn a lovely golden brown, which usually takes about 20 minutes. The sweetness from the caramelized onions is what's going to elevate your homemade roasted tomato basil soup.
Blend and combine
Once your tomatoes and garlic have roasted to perfection, let them cool for a moment before transferring them to a food processor or blender. Blend until smooth, then toss in the caramelized onions and ½ cup of packed basil leaves. For those without a blender, an immersion blender in the pot works just fine!
Simmer and season
Now it’s time to bring everything together. Transfer your blended mixture back to the pot over medium-low heat. Stir in ½ teaspoon of dried oregano and add 1-2 cups of water or vegetarian broth, depending on how thick you prefer your soup. Season with salt and pepper to taste. Here’s where you can get creative—consider adding a splash of coconut milk for creaminess or some Parmesan cheese for that delightful tang. Allow the soup to simmer for 10 minutes before serving.
Serve your homemade roasted tomato basil soup garnished with a sprinkle of Parmesan or alongside a grilled cheese sandwich for the ultimate cozy meal!
By incorporating fresh, flavorful ingredients at each stage, you'll find that the process is as enjoyable as the delicious result. Happy cooking!
