Hasn’t everyone, at some point, craved a truly comforting tomato soup? This Oven Roasted Tomato Soup delivers rich flavor with minimal effort. It’s creamy, warming, and uses simple ingredients you may already have on hand—perfect for chilly nights, casual dinners, or feeding a crowd.
Oven Roasted Tomato Soup
This oven-roasted version concentrates tomato flavor while keeping the recipe straightforward. Roasting brings out natural sweetness and adds a slight caramelized depth that blends beautifully with a touch of cream and fresh basil. Serve with grilled cheese, croutons, or a sprinkle of Parmesan for a classic pairing.
How to Roast Tomatoes
Roasting is simple: halve the tomatoes, toss them with olive oil, salt, and pepper, add diced onion on the baking sheet, and roast until the edges brown and concentrate in flavor. Adding minced garlic during the final minutes prevents it from burning while contributing a mellow garlicky note. This hands-off method delivers deep, layered flavor without extra work.
Can this be made on the grill?
Yes. Roasting tomatoes on a grill at about 375°F gives them a subtle smoky, wood-fired aroma that complements the soup well. Use a heat-safe pan or a grill-safe sheet, and follow the same timing and steps as oven roasting.
How hard is this to make?
Not hard at all. The technique is forgiving, and the ingredients are basic—tomatoes, onion, olive oil, a little garlic, half-and-half, and basil. Even new cooks can produce a rich, restaurant-style soup. It’s also easy to scale up for larger groups.
What toppings work best?
Tomato soup is versatile—choose toppings to match your mood. Classic pairings include grilled cheese or crusty bread. For finishing touches, try:
- Shredded cheddar or a Parmesan grate
- A dollop of sour cream or Greek yogurt
- Fresh chopped parsley or basil
- Chopped chives for brightness
- Crunchy croutons for texture
Mix and match toppings to find your favorite combination.
How to make this recipe
This recipe is straightforward and forgiving. Read through the steps before starting, then follow the timings and tips below for best results.
Preheat your oven or grill to 375°F. Slice the tomatoes in half and toss them with olive oil. Arrange the tomatoes and diced onion on a parchment-lined or silicone-lined baking sheet, then season with salt and pepper. Roast for 20–30 minutes, until the tomatoes begin to brown at the edges and concentrate in color and flavor. Add minced garlic in the last five minutes to avoid burning and to keep the garlic mellow.
Carefully transfer the roasted tomatoes, onions, and any juices to a blender and puree until smooth. Return the blended soup to a pot on low heat, stir in the half-and-half and chopped fresh basil, and warm through gently. Taste and adjust salt and pepper as needed. Serve hot with your preferred toppings.
This soup can be made a day ahead and reheated gently. It also freezes well—cool completely before freezing in airtight containers for convenient future meals.
