I sat down with Chef Yolanda “Yoli” Treviño in the back corner of her San Antonio kitchen, between the lunch rush and dinner prep. She has been making sopa de tortilla for 31 years — first at her grandmother’s table, then at a taqueria off Culebra Road, and now at her own spot on South Flores.
She agreed to talk on one condition: that I let her be blunt.
“I don’t care if your bowl looks pretty on Instagram,” she told me, wiping down a comal. “If the broth is thin, you missed the point.”
Quick Answer 🔎
The #1 Mistake Home Cooks Make with Tortilla Soup
The biggest mistake is treating tortilla soup like a tomato-and-chicken soup with chips on top. Real tortilla soup is a chile and tortilla soup. The tortillas get fried and blended into the broth as a thickener, and the depth comes from toasted dried chiles — not a spoonful of chili powder. Fix those two things and your soup goes from fine to unforgettable.
Here is our conversation, edited for length and clarity.
The #1 Mistake: Treating the Broth Like a Supporting Actor
Q: Let’s start with the big one. What is the number one mistake you see home cooks make?
They spend all their energy on the topping bar and almost none on the broth. I get it. The toppings are fun. They’re colorful. Everyone wants to post a picture of the avocado and the crema. But the broth is the soup. The toppings are just the outfit.
The home version I see is basically chicken broth, a can of diced tomatoes, some cumin, and a handful of crushed chips at the end. That is not tortilla soup. That is chicken soup wearing a costume.
Two things are missing:
- Toasted dried chiles to build the base
- Tortillas blended into the broth to give it body
Do those two things and you will not believe it came out of your own kitchen.
Chile Powder Is Not a Substitute for Chiles
Q: A lot of recipes call for chili powder. What’s wrong with that?
Nothing is wrong with it. It’s just doing a different job. The chili powder blend in your spice cabinet is mostly cumin, oregano, garlic powder, and a little ground chile. It’s a seasoning mix. It is not a chile base.
When you toast whole dried chiles and blend them into your broth, you get fruitiness, smokiness, and a natural sweetness you cannot fake with powder. You also get that deep brick-red color — and that color does not come from tomatoes.
Q: Which chiles should a beginner buy?
Start with three. That’s it.
| Chile | Heat Level | What It Tastes Like | What It Does in the Pot |
|---|---|---|---|
| Guajillo | Mild to medium | Fruity, tangy, a little berry-like | Gives color and backbone |
| Ancho | Mild | Sweet, raisin, slightly smoky | Adds body and roundness |
| Pasilla | Mild | Earthy, herbal, faint cocoa | Adds depth |
If you want smoke, add one or two dried chipotles (moritas). If you want real heat, add chile de árbol. But start with those first three.
Q: How do you prep them?
Toast them. This is not optional.
- Wipe the chiles clean with a damp towel. Pull off the stems and shake out the seeds.
- Heat a dry skillet or comal over medium.
- Press the chiles flat for 30 to 60 seconds per side. You want them pliable and fragrant — like toasted bread. If they puff up and smell bitter, you burned them. Throw those out and start over.
- Cover them with hot water and soak for 20 to 30 minutes until soft.
- Blend the soaked chiles with a ladle of the soaking liquid and strain.
That strained purée is your soup’s soul.
One warning: do not rub your eyes after handling chiles. I learned that the hard way in 1994.
The Tortilla Trick Nobody Tells You
Q: You mentioned tortillas blended into the broth. Walk me through that.
This is the part that shocks people.
In a real sopa de tortilla, tortillas do two jobs. Some get fried crisp and go on top. Others get fried and blended into the soup to thicken it.
That blended tortilla is what gives you a broth with a little weight to it. Not creamy, not thick like gravy — just enough body to coat a spoon.
Q: How do you do it at home?
Here is the simple version:
- Take 3 to 4 corn tortillas. Day-old ones work best.
- Cut them into strips or rough pieces.
- Fry them in about an inch of neutral oil at 350°F for 45 to 60 seconds until they are golden and puffed. Do not let them go dark brown — that turns bitter.
- Drain them on a paper towel.
- Blend those fried tortillas with your chile purée and a cup of broth until smooth.
- Pour that mixture into your pot and let it simmer.
That’s it. That’s the step most home cooks skip, and it’s the step that makes the biggest difference.
Q: Can you just use store-bought tortilla chips?
For the topping? Sure, in a pinch. For blending into the broth? No.
Bagged chips are fried in oil that has been used all day, and they’re usually salted heavily. They’ll make your broth greasy and muddy. Fry your own. It takes ten minutes.

Char Your Vegetables. Every Single Time.
Q: Let’s talk vegetables. What do home cooks get wrong there?
They dump raw onions and canned tomatoes straight into the pot.
You need to char your tomatoes, onions, and garlic first. That step is where the smoke comes from. Not from a spice jar — from actual fire.
The high heat caramelizes the natural sugars and blisters the skins. That is the flavor that makes people say “this tastes like a restaurant.”
You have three options:
- Gas flame: Put whole tomatoes and thick onion wedges right on the grate over a medium-high burner. Turn every 2 to 3 minutes. About 10 to 12 minutes total.
- Oven broiler: Top rack, 4 to 6 inches from the element. Broil 5 to 7 minutes per side.
- Cast-iron skillet: Dry pan, medium-high heat, 4 to 5 minutes per side.
Leave the blackened bits on. That is not burnt — that is flavor.
Q: Do you peel them after charring?
For a rustic bowl, leave the skins on. For a smoother broth, peel them. Both are correct. I leave them on at home and peel them at the restaurant. Don’t tell my grandmother.

Broth, Chicken, and the Boiling Problem
Q: What about the broth itself?
Use good chicken broth. If you have homemade stock, use it. If you’re buying it, buy low-sodium so you can control your own salt.
Some people use bone broth for the collagen. That’s fine. It adds body. But it’s not required.
Q: And the chicken?
Here is a mistake I see constantly: people boil the chicken for 45 minutes until it turns into sawdust.
Cook your chicken separately, or poach it gently and pull it out at 165°F. Shred it and add it back at the end. If you’re using rotisserie chicken, add it in the last five minutes so it just warms through.
Chicken that has been boiling for an hour has no texture left. It’s just fiber.
Q: Any other broth mistakes?
Yes. Do not hard-boil your soup after you add the chile purée. A gentle simmer is all you need. A rolling boil will make the broth cloudy and dull the chile flavor.
Toppings: What Belongs and What Doesn’t
Q: Let’s settle this. What actually goes on top?
For me, the classic lineup is:
- Fried tortilla strips
- Diced avocado
- Queso fresco or a mild crumbling cheese
- Mexican crema
- Cilantro
- Lime
- Sliced raw onion or pickled red onion
- A few strips of toasted pasilla chile
That’s a proper bowl. Everything else is extra.
Q: What about black beans and corn?
That’s the Tex-Mex version, and I make it too. Beans and corn turn it into a full meal. I’m not against it. I’m just saying that if you’re calling it sopa de tortilla, the beans and corn are a bonus, not the base.
Q: What topping should people stop putting on?
Heavy sour cream. A big cold scoop on top of a hot bowl cools the soup down and hides the chile. Use crema, and use it thin. A drizzle, not a dollop.
Also, stop putting the tortilla strips in the pot. They turn to mush in 90 seconds.
Seasoning: The Layers That Matter
Q: What seasoning mistakes do you see?
Two big ones.
First, they under-salt. Salt in layers. Salt the chicken. Salt the vegetables while they char. Salt the broth a little at each stage. Then taste at the very end and adjust. If your soup tastes flat and you can’t figure out why, it’s almost always salt.
Second, they forget acid. Lime juice goes in off the heat, right before serving. If you add it early and boil it, you lose the brightness. That squeeze of lime is what makes the whole bowl wake up.
Q: What about cumin?
Toast whole cumin seeds in a dry pan for 30 seconds, then grind them. It takes two extra minutes and it’s ten times better than the pre-ground jar that’s been sitting in your cabinet since 2019.
Pre-ground spices lose their punch after about six months. If your cumin smells like dust, toss it.
The Chef’s Blueprint
Q: If someone wants to make this tonight, give them the numbers.
This makes about 4 quarts, which feeds 10 to 12 people as a main course.
| Ingredient | Amount |
|---|---|
| Dried chiles (guajillo, ancho, pasilla) | 4 to 6 total |
| Roma tomatoes | 4 to 5, charred |
| Yellow onion | 1 large, cut in wedges and charred |
| Garlic | 3 cloves, charred |
| Corn tortillas (for blending) | 3 to 4, fried |
| Corn tortillas (for strips) | 6 to 8, fried |
| Chicken broth | 8 cups, low-sodium |
| Shredded chicken | 1.5 to 2 pounds |
| Cumin | 1 teaspoon, freshly toasted and ground |
| Lime juice | 1 to 2 limes, added off heat |
Simmer everything together for 20 to 30 minutes. Taste. Salt. Lime. Serve.
Feeding a Crowd Without Losing Your Mind
Q: What changes when you’re cooking for a party?
Three things.
- Make the base ahead. The chile purée and blended tortilla base can be made up to 2 days in advance and stored in the fridge. It actually gets better overnight.
- Hold it hot, not boiling. A slow cooker on the Warm setting keeps soup at a safe holding temperature. Check it with a thermometer — you want 140°F or above. Reheat leftovers to 165°F.
- Never leave toppings out more than 2 hours. Cheese, crema, avocado, and cut vegetables are perishable. If it’s a hot day, that window drops to 1 hour.
And put the tortilla strips out in small bowls. Refill them from a bag in the pantry. That way they stay crunchy all night.

Quick-Fire Round
Q: Fastest way to ruin tortilla soup?
A: Boiling the chicken for an hour.
Q: One ingredient people should buy better?
A: Your chiles. Go to a mercado or a Latin grocery store. The turnover is higher, so they’re fresher.
Q: One shortcut you actually endorse?
A: Rotisserie chicken. Shred it, add it at the end.
Q: One shortcut you don’t?
A: Crushed chips as a thickener.
Q: Best thing to serve on the side?
A warm flour tortilla with butter. That’s a South Texas thing. Trust me.
Q: What should a home cook focus on first?
A: The broth. Toppings are easy. Anyone can dice an avocado. Making a broth that tastes like it took all day — that’s the skill. And it only takes about 40 minutes once you know what you’re doing.
Common Questions
What is the number one mistake in chicken tortilla soup?
Skipping the toasted dried chiles and the blended fried tortillas. Those two steps build the flavor and body. Without them, you get thin tomato-chicken broth.
Do I have to use dried chiles?
For authentic flavor, yes. If you truly can’t find them, use a good ancho chile powder plus a little smoked paprika, and accept that it won’t be quite the same.
Can I blend store-bought tortilla chips into the broth?
You can, but they’re salty and often greasy. Fry your own corn tortillas at 350°F for 45 to 60 seconds.
How do I keep the tortilla strips crispy?
Keep them out of the pot. Put them in a bowl on the table and let guests add their own.
How long does the soup last in the fridge?
About 4 days in an airtight container. The flavor gets better on days two and three.
Can I freeze it?
Yes, up to 3 months. Freeze the base without toppings. Thaw overnight in the fridge and reheat gently to 165°F.
What temperature should I hold soup at for a party?
Keep hot soup at 140°F or above. Per USDA guidelines, don’t leave perishable toppings out longer than 2 hours (1 hour if it’s above 90°F).
The Takeaway
Chef Yoli put it best when she walked me out.
“Everybody wants to talk about the toppings,” she said. “Nobody wants to talk about the comal. But that’s where the flavor is. Get the broth right, and the rest takes care of itself.”
So here’s your homework: toast your chiles. Char your vegetables. Fry a few tortillas and blend them in. Do that once, and you’ll never go back to the thin stuff.
