Roasted tomatillo soup is one of those meals I make when the day runs long and I want something warm without a lot of work. The smell of the vegetables roasting always tells me dinner is on the right track. After all these years, Chef Thomas still likes recipes that keep things simple and full of flavor. If you’re new to tomatillos, take a look at what a tomatillo is before you start. This soup brings a nice balance of freshness and comfort to the table.

What Is Roasted tomatillo soup?
Roasted tomatillo soup is a smooth, savory soup made by roasting tomatillos and blending them with aromatics and broth. It has roots in Mexican home cooking, where tomatillos have been used for sauces and soups for generations and are a staple in many regional dishes. Unlike green salsa or cream-based vegetable soups, this soup gets its bright, slightly tangy flavor from roasted tomatillos, which add both depth and freshness. Home cooks enjoy making it because the ingredients are simple, the roasting does most of the work, and the soup can be served as a light meal or a starter. Some versions include chiles or cream, but the base stays pleasantly simple. A quick look at the ingredients shows how a few basic items come together in the pot.

Instructions
- Turn on the oven broiler. Line a baking sheet with foil.
- Place the tomatillos and halved peppers (cut side down) on the lined baking sheet. Broil for 7 to 10 minutes until charred.
- When the tomatillos and peppers are finished roasting, transfer them to a food processor or high-powered blender. Add the cilantro. Blend or pulse until smooth. The consistency should be similar to a thin salsa.

- Stir in the garlic, cumin, coriander, and salt. Cook for another minute until fragrant.
- Pour the tomatillo mixture into the pot, along with the vegetable broth and lime juice. Use 3 cups of broth for a thicker soup and 4 cups for a thinner consistency. Add the beans and corn at this time.
- Increase heat to bring to a boil. Reduce heat to maintain a simmer. Cook for 15 to 20 minutes, uncovered, to allow the soup to thicken a little. Stir occasionally.

Notes
Ingredients for Roasted Tomatillo Soup
| Ingredient | Amount |
|---|---|
| tomatillos | 2 pounds |
| jalapeño peppers | 2 |
| poblano pepper | 1 |
| cilantro leaves | ¼ to ½ cup |
| extra virgin olive oil | 1 tablespoon |
| white onion | 1 |
| garlic | 3 cloves |
| ground cumin | ½ teaspoon |
| ground coriander | ½ teaspoon |
| kosher salt | ½ teaspoon |
| vegetable broth | 3 to 4 cups |
| lime | 1 |
| pinto beans | 1 15-ounce can |
| chickpeas | 1 15-ounce can |
| corn | 1 15-ounce can |
I like this combination because the roasted vegetables build a deep, savory base while the beans and corn give the soup a hearty texture. The lime and cilantro bring a little freshness that keeps everything balanced. Chef Thomas often recommends learning a bit more about tomatillos because understanding the main ingredient helps explain the soup’s bright flavor.
Roasted tomatillo soup — Ingredient Substitutions
Sometimes you open the fridge and realize you’re missing an ingredient or need to work with what you already have. A few simple swaps can still give you a flavorful pot of roasted tomatillo soup without changing the spirit of the recipe.
| Original Ingredient | Best Substitute | Notes (ratio changes, flavor impact, tips) |
|---|---|---|
| Tomatillos | Green tomatoes | Use the same amount. Green tomatoes are less tangy, so add an extra squeeze of lime at the end if the soup tastes flat. |
| Jalapeño peppers | Serrano peppers | Use one serrano for every two jalapeños because serranos are usually hotter. |
| Poblano pepper | Green bell pepper | Use the same amount. The soup will be milder and a little sweeter. |
| Cilantro leaves | Flat-leaf parsley | Use the same amount. Parsley gives freshness but lacks the citrus-like flavor of cilantro. |
| Extra virgin olive oil | Avocado oil | Use the same amount. Both handle sautéing well and have a mild flavor. |
| White onion | Yellow onion | Use the same amount. Yellow onion adds a slightly deeper sweetness when cooked. |
| Garlic | Garlic powder | Use ⅛ teaspoon garlic powder for each clove of garlic. Add it with the spices instead of the onions. |
| Ground cumin | Chili powder | Use the same amount. The flavor becomes earthier and slightly more complex. |
| Ground coriander | Ground cumin | Use half the amount. Too much cumin can overpower the bright flavor of the tomatillos. |
| Vegetable broth | Chicken broth | Use the same amount. This keeps the soup gluten-free if you choose a certified gluten-free broth. |
| Lime | Lemon | Use the same amount of juice. Lemon adds brightness but tastes a little sharper. |
| Pinto beans | Black beans | Use the same amount. Black beans make the soup slightly heartier and darker in color. |
| Chickpeas | Cannellini beans | Use the same amount. They blend into the soup with a softer texture. |
| Corn | Frozen corn kernels | Use the same amount. No need to thaw before adding them to the pot. |
The swap that changes this recipe the most is replacing the tomatillos. Green tomatoes make a good backup, but the soup loses some of its signature tangy flavor. If you make that substitution, taste the soup before serving and add a little more lime juice if it needs brightness.
How to Make Roasted Tomatillo Soup
Step 1: Prepare the oven
I turn on the oven broiler and line a baking sheet with foil so cleanup stays simple. Having the pan ready makes the next steps move quickly.
Visual idea: A foil-lined baking sheet sitting on a kitchen counter.
Step 2: Broil the vegetables
I place the tomatillos and halved peppers cut side down on the baking sheet and broil them for 7 to 10 minutes until they look charred and smell slightly smoky.
Chef Thomas’s Tip:
A few black spots are good. They add depth to the soup without making it taste burnt.
Visual idea: Tomatillos and peppers under the broiler with blistered skins.
Step 3: Blend the roasted vegetables
I transfer the roasted vegetables to a food processor or high-powered blender and add the cilantro. Then I blend until the mixture looks like a thin green salsa.
Visual idea: Green tomatillo mixture blending in a food processor.
Step 4: Cook the onion
I warm the olive oil in a soup pot over medium heat and cook the diced onion until it turns soft and translucent.
Visual idea: Diced onion cooking in a pot with a wooden spoon.
Step 5: Add the seasonings
I stir in the garlic, cumin, coriander, and salt and cook for another minute. The spices should smell warm and fragrant.
Chef Thomas’s Tip:
I keep the heat moderate here because garlic can turn bitter if it cooks too quickly.
Visual idea: Garlic and spices being stirred into softened onions.
Step 6: Build the soup
I pour in the tomatillo mixture, vegetable broth, and lime juice, then add the beans and corn. For a thicker roasted tomatillo soup, I use 3 cups of broth, and for a lighter texture, I add 4 cups.
Visual idea: Green soup base being poured into a pot with beans and corn.
Step 7: Simmer gently
I bring the soup to a boil, then reduce the heat and let it simmer uncovered for 15 to 20 minutes. The soup thickens slightly as the flavors come together.
Chef Thomas’s Tip:
I give the pot an occasional stir so the beans and corn stay evenly mixed.
Visual idea: A pot of soup gently simmering with steam rising.
Step 8: Serve and enjoy
I turn off the heat and ladle the soup into bowls while it is still hot. The finished soup should smell fresh and savory with a bright green color.
Visual idea: Bowls of roasted tomatillo soup served on a table with spoons nearby.
How I Serve Roasted Tomatillo Soup
Roasted tomatillo soup is the kind of meal I make when I want dinner to be warm and simple, and Chef Thomas often puts it on the table at the end of a busy week with very little fuss.
I usually serve it in deep bowls with a little extra cilantro on top and a piece of warm bread on the side. The soup is hearty enough for a light supper, especially when the beans and corn have had time to soak up the flavors.
If I’m feeding a few extra people, I set out small toppings and let everyone finish their own bowl. When I have leftovers, I often serve a smaller portion alongside a sandwich for lunch the next day. If you’re wondering whether fresh or canned tomatillos make a difference, I put together a guide on fresh vs canned tomatillos that may help.
- Warm crusty bread
- A simple green salad
- Cooked white rice
- Grilled chicken on the side
- Sliced avocado for a fresh finish
Variations and Adjustments for Roasted Tomatillo Soup
Roasted tomatillo soup is a recipe I have adjusted many times over the years, and Chef Thomas has found that a few small changes can make it fit different meals without changing its character.
Mild or Spicy
If I want a milder soup, I use only one jalapeño or remove every seed from the peppers before roasting. For a little more heat, I leave some of the seeds in or add an extra jalapeño.
Texture Adjustments
I use 3 cups of broth when I want the soup thicker and hearty enough for a main meal. When I am serving it as a starter, I usually add the full 4 cups for a lighter, more spoonable texture.
- Blend the vegetables completely for a smooth soup.
- Pulse the mixture a few times if you prefer a little texture.
Protein or Ingredient Swaps
I sometimes use black beans instead of pinto beans when that is what I have in the pantry. White beans also work and give the soup a softer texture.
- Frozen corn can replace canned corn.
- Yellow onion works in place of white onion without changing the recipe much.
Cooking Method Changes
When I do not want to use the broiler, I roast the vegetables in a hot oven until they are soft and lightly charred around the edges. The soup loses a little smokiness, but it still has plenty of flavor.
The base of this soup is simple and reliable, so I keep the changes small and let the roasted tomatillos stay at the center of the bowl.
Storing and Making Roasted Tomatillo Soup Ahead
Roasted tomatillo soup is one of those meals I often make in a larger batch, and Chef Thomas has learned that the leftovers can be just as good the next day with very little effort.
I store the soup in a covered container in the refrigerator for up to 5 days. The broth may thicken a little as it sits, and the flavors usually settle together in a nice way by the second day.
This soup freezes well. I let it cool completely before transferring it to freezer-safe containers and leave a little space at the top because liquids expand as they freeze. I try to use it within about 6 months for the best flavor.
I sometimes roast the vegetables and blend the tomatillo mixture a day ahead, then keep it in the refrigerator until I am ready to finish the soup. The beans and corn can wait until cooking day, which keeps the whole process feeling easy.
For reheating, I prefer a saucepan over medium-low heat so the soup warms gently. If it seems too thick, I stir in a splash of broth or water. I avoid boiling it hard because that can dull the fresh flavor and change the texture a bit.
Frequently Asked Questions About Roasted Tomatillo Soup
Can I make this soup less spicy?
Yes. I usually remove all the seeds from the peppers when I want a milder soup. You can also use only one jalapeño and still get plenty of flavor from the roasted vegetables.
Can I use green tomatoes instead of tomatillos?
You can, but the flavor will be different. Green tomatoes are less tangy and slightly sweeter. I like to add a little extra lime juice if I make that swap.
Why is my soup too thick?
This soup thickens as it cooks and even more after it sits for a while. I simply stir in a splash of vegetable broth or water until it reaches the texture I want.
Can I make roasted tomatillo soup ahead of time?
Yes. I often make it a day ahead because the flavors settle together nicely overnight. Store it in the refrigerator and warm it gently before serving.
Can I freeze the leftovers?
Yes, this soup freezes well. Chef Thomas likes to cool it completely before freezing and leave a little room in the container for expansion.
What can I use instead of pinto beans or chickpeas?
Black beans or white beans work well in this recipe. The soup may taste a little different, but it will still have a hearty texture.
Why does my soup taste too tart?
Tomatillos can vary in flavor from one batch to another. Chef Thomas usually balances extra tartness by adding a little more broth and letting the soup simmer for a few extra minutes.
Final Thoughts on Roasted Tomatillo Soup
Roasted tomatillo soup is one of those recipes I come back to because it asks very little from the cook and still brings a warm, balanced bowl to the table. Chef Thomas has made versions of this soup for many years, and I still appreciate how easily it fits into everyday meals. If you happen to have extra tomatillos on hand, I sometimes move from this soup to tomatillo chicken recipe for another simple dinner that uses many of the same flavors.
