It’s perfect for weeknights, meal prep, or a cozy lunch. Pair it with a grilled cheese or a slice of crusty bread, and you’re set.
What Makes This Recipe So Good
- Big flavor, minimal effort: The air fryer concentrates the sweetness of tomatoes and peppers in minutes, no oven preheating needed.
- Balanced and bright: Sweet peppers, tomatoes, and a splash of vinegar create a smooth, tangy-sweet finish.
- Flexible and forgiving: Use fresh or canned tomatoes, any color peppers, and adjust the heat or creaminess to taste.
- Light but satisfying: It’s naturally vegetarian and can be made vegan. Add beans or grains if you want more heft.
- Great for make-ahead: The flavor improves after a day in the fridge, and it freezes well.
Ingredients
- 2 pounds ripe tomatoes (Roma or vine-ripened), halved or quartered
- 2 large sweet bell peppers (red, yellow, or orange), seeded and sliced into thick strips
- 1 medium red onion, cut into wedges
- 4 cloves garlic, peeled
- 2 tablespoons olive oil
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon freshly ground black pepper
- 1 teaspoon smoked paprika (or sweet paprika if you prefer milder flavor)
- 1/2 teaspoon dried oregano or thyme
- 1–2 teaspoons sugar or honey (optional, to balance acidity)
- 3–4 cups low-sodium vegetable broth (start with 3 and add more to thin)
- 1–2 tablespoons red wine vinegar or sherry vinegar
- 1/4 cup heavy cream or coconut milk (optional, for creaminess)
- Fresh basil or parsley, for garnish
- Crushed red pepper flakes (optional, for heat)
How to Make It
- Prep the veggies: Add tomatoes, peppers, onion, and garlic to a large bowl.
Toss with olive oil, salt, pepper, paprika, and oregano until evenly coated.
- Air fry in batches if needed: Arrange the vegetables in a single layer in your air fryer basket. Cook at 400°F (200°C) for 14–18 minutes, shaking halfway, until edges are charred and tomatoes look collapsed.
- Deglaze the flavor: If your air fryer has a tray with browned bits, carefully scrape them into the pot—they add a lot of flavor.
- Simmer briefly: Transfer roasted vegetables to a pot. Add 3 cups of vegetable broth.
Bring to a gentle simmer for 5–7 minutes to meld flavors.
- Balance the acidity: Stir in vinegar and, if needed, a teaspoon of sugar or honey to round out the tomatoes. Taste and adjust salt and pepper.
- Blend until smooth: Use an immersion blender to puree until silky. For extra smoothness, blend in a countertop blender in batches.
Add more broth to reach your preferred consistency.
- Make it creamy (optional): Stir in heavy cream or coconut milk. Warm through without boiling to prevent curdling.
- Finish and serve: Ladle into bowls and top with fresh basil or parsley. Add a pinch of red pepper flakes, a drizzle of olive oil, or a dollop of yogurt if you like.
Keeping It Fresh
- Refrigerate: Store in an airtight container for up to 4 days.
The flavor deepens on day two.
- Freeze: Cool completely, then freeze for up to 3 months. Leave a little headspace in the container for expansion.
- Reheat: Warm gently on the stove over low to medium heat, adding a splash of broth or water if it thickens. Avoid boiling if you added cream.
- Meal prep tip: Freeze in single portions for easy lunches.
Thaw overnight in the fridge or reheat from frozen on low.
Health Benefits
- Antioxidant-rich: Tomatoes bring lycopene, which is linked to heart and skin health. Roasting can make lycopene more available.
- Low in calories, big on nutrients: Sweet peppers add vitamins A and C, plus fiber for fullness.
- Heart-friendly fats: A bit of olive oil helps your body absorb fat-soluble vitamins and carotenoids.
- Flexible for dietary needs: Easily made vegan, dairy-free, or gluten-free. Use coconut milk or skip cream entirely.
Pitfalls to Watch Out For
- Overcrowding the basket: Piling the vegetables leads to steaming instead of roasting.
Work in batches for caramelization.
- Skipping the seasoning: Salt brings out natural sweetness and helps everything taste balanced. Season before and after blending.
- Too thin or too thick: Start with less broth and add more gradually. It’s easier to thin than to fix a watery soup.
- Harsh acidity: Some tomatoes are very tart.
A small amount of sweetener and a splash of vinegar for complexity can help you hit the right note.
- Boiling after adding cream: If you use dairy, keep the heat gentle to prevent curdling.
Alternatives
- Tomatoes: Use canned whole tomatoes (two 14.5-ounce cans, drained) if fresh tomatoes are out of season. Roast them briefly in the air fryer to concentrate flavor.
- Peppers: Try roasted piquillo peppers or jarred roasted red peppers. Drain them well before blending.
- Spices: Swap smoked paprika for harissa or chipotle for a smoky kick, or add cumin and coriander for a warmer profile.
- Creaminess: Blend in white beans or a small potato for body instead of cream.
A spoonful of cashew cream also works well.
- Protein add-ins: Top with crispy chickpeas, grilled shrimp, or shredded rotisserie chicken for a more filling meal.
- Toppings: Try crumbled feta, garlic croutons, pesto, or a swirl of plain yogurt.
FAQ
Can I make this without an air fryer?
Yes. Roast the vegetables on a sheet pan at 425°F (220°C) for 25–35 minutes, tossing once, until charred and softened. Then proceed with simmering and blending.
How do I make it spicier?
Add a pinch of red pepper flakes before roasting, or blend in half a roasted jalapeño.
Smoked chipotle powder also adds heat and depth.
What if my soup tastes too acidic?
Stir in a little sugar or honey, 1 teaspoon at a time. A splash more olive oil or a spoonful of cream can also soften the edges. Always taste as you go.
Can I use cherry tomatoes?
Absolutely.
They roast quickly and get extra sweet. Use about 2 pints, and check a few minutes earlier since they cook fast.
Is this soup freezer-friendly?
Yes. For the best texture, freeze it before adding cream.
Add the cream or coconut milk when reheating.
How can I make it thicker?
Blend in a roasted potato, a handful of cooked rice, or a half cup of rinsed white beans. You can also simmer the blended soup uncovered to reduce.
What can I serve with it?
Grilled cheese, garlic bread, warm pita, or a simple green salad. A drizzle of basil pesto makes it feel special.
