Tomatillo soup is a vibrant, tangy dish that brings the fresh, citrusy flavor of tomatillos to the forefront. Perfect for warming up on a cool day or serving as a light, flavorful meal, this soup is a staple in Mexican-inspired kitchens. Its combination of roasted tomatillos, aromatics, and simple spices makes it both easy to prepare and deeply satisfying.
Ingredients
- 1 1/2 pounds fresh tomatillos (about 8-10 medium), husked and rinsed
- 2 tablespoons olive oil, divided
- 1 large yellow onion, diced
- 4 garlic cloves, minced
- 1-2 jalapeño peppers, seeded and chopped (adjust for heat preference)
- 1 teaspoon ground cumin
- 1 teaspoon dried oregano (Mexican oregano if available)
- 1/2 teaspoon salt, plus more to taste
- 1/4 teaspoon freshly ground black pepper
- 4 cups low-sodium chicken broth (or vegetable broth for vegetarian)
- 1 cup cooked shredded chicken (optional, for a heartier soup)
- 1/2 cup fresh cilantro leaves, chopped
- Juice of 1 lime (about 2 tablespoons)
- Sliced avocado, for serving (optional)
- Crumbled queso fresco or feta cheese, for serving (optional)
- Warm tortilla strips or chips, for serving (optional)
Instructions
- Roast the tomatillos: Preheat your oven to 425°F (220°C). Slice the tomatillos in half and place them cut-side down on a parchment-lined baking sheet. Drizzle with 1 tablespoon olive oil. Roast for 20-25 minutes, or until the tomatillos are soft and their skins are blistered in spots.
- Sauté the aromatics: While the tomatillos roast, heat the remaining 1 tablespoon olive oil in a large pot or Dutch oven over medium heat. Add the diced onion and cook, stirring occasionally, until softened and translucent, about 5-7 minutes. Add the garlic and jalapeños and sauté for another 1-2 minutes, until fragrant.
- Spice it up: Stir in the ground cumin, oregano, salt, and black pepper. Cook for 1 minute to toast the spices.
- Blend the base: Once the tomatillos are roasted, carefully transfer them (and any juices from the baking sheet) into a blender or food processor. Add the sautéed onion mixture. Blend until smooth. For a chunkier soup, pulse a few times; for a smooth soup, blend thoroughly.
- Simmer the soup: Pour the tomatillo mixture back into the pot. Add the chicken broth and bring to a simmer over medium heat. Cook for 10-15 minutes, stirring occasionally. If using, stir in the shredded chicken and heat through for another 3-5 minutes.
- Finish and season: Remove the soup from heat. Stir in the chopped cilantro and lime juice. Taste and adjust salt or lime juice as needed.
- Serve: Ladle the soup into bowls. Top with sliced avocado, crumbled queso fresco, and tortilla strips or chips if desired. Serve hot.
Tips
- Substitute for tomatillos: If you can’t find fresh tomatillos, use canned tomatillos (drained), though the flavor will be slightly less bright. Green tomatoes with a splash of lime can work in a pinch.
- Make it vegetarian/vegan: Use vegetable broth and omit the chicken and cheese toppings. Add a can of white beans or diced potatoes for extra heartiness.
- Control the heat: Remove seeds from the jalapeños for a milder soup, or swap in a milder pepper like poblano. For extra spice, leave the seeds in or add a serrano pepper.
- Common mistake: Don’t skip roasting the tomatillos—this step deepens their flavor and tames their natural tartness.
Serving Suggestions
- Serve with warm corn or flour tortillas on the side for dipping.
- Top with diced avocado, chopped fresh cilantro, and a dollop of sour cream or Greek yogurt for added creaminess.
- Sprinkle with toasted pumpkin seeds (pepitas) for crunch.
- Pair with a crisp, light salad—like jicama and orange—for a refreshing contrast.
Variations
- Tomatillo-Poblano Soup: Roast 1-2 poblano peppers alongside the tomatillos, peel, chop, and blend them in for a smoky, slightly sweet flavor.
- Hearty Bean Addition: Stir in a can of rinsed pinto or white beans for extra protein and texture.
- Creamy Tomatillo Soup: After blending, add 1/2 cup heavy cream or coconut milk for a richer, silkier soup.
- Chilled Soup: Let the blended soup cool completely, then chill for several hours. Serve cold with extra lime and fresh herbs as a summer starter.
Storage and Reheating
Let the soup cool to room temperature before storing. Transfer to airtight containers and refrigerate for up to 4 days. For longer storage, freeze the soup (without toppings) for up to 2 months. To reheat, thaw overnight in the refrigerator if frozen. Warm gently on the stovetop over medium heat, stirring occasionally, until steaming hot. If the soup thickens after refrigeration, stir in a splash of broth or water to reach your desired consistency. Always reheat to at least 165°F (74°C) for food safety.
Frequently Asked Questions
- What are tomatillos, and how are they different from green tomatoes?
- Tomatillos are small, round fruits covered in a papery husk, commonly used in Mexican cooking. They have a tart, citrusy flavor distinct from green tomatoes, which are simply unripe tomatoes. Tomatillos provide a unique tang and body to soups and salsas that green tomatoes can’t fully replicate.
- Can I make this soup ahead of time?
- Absolutely! Tomatillo soup actually tastes even better the next day as the flavors meld. Make it a day in advance, refrigerate, and reheat gently before serving. Add fresh toppings just before serving for best texture and flavor.
- Is this soup spicy?
- The heat level is very customizable. With seeded jalapeños, the soup is mild to medium. For a spicier version, leave the seeds in or add an extra pepper. For less heat, use only half a jalapeño or substitute a milder pepper.
- Can I use an immersion blender instead of a countertop blender?
- Yes, you can use an immersion blender directly in the pot to blend the soup. For best results, ensure the tomatillos and aromatics are very soft before blending. The soup may be slightly chunkier, but it will still be delicious.
- How do I know when tomatillos are ripe?
- Ripe tomatillos are firm, bright green, and fill out their papery husks. The husk may split slightly when the fruit is fully mature. Avoid tomatillos that are yellowing or feel sticky and soft.
- Can I freeze tomatillo soup?
- Yes, tomatillo soup freezes well. Cool completely, transfer to airtight containers, and freeze for up to 2 months. Thaw in the refrigerator before reheating. Add fresh garnishes after reheating for the best flavor and texture.
