What is Sopa de Letras?
Sopa de Letras, or alphabet soup, is a home-style Mexican soup made with tiny letter-shaped pasta in a savoury broth. It belongs to the family of simple noodle soups often served as a comforting first course.
This version gets its tomato flavour from a freshly blended mix of tomatoes, onion and garlic. Browning the pasta first adds a toasty note before the broth goes in.

The alphabet pasta provides most of the carbohydrates, while the oil contributes much of the fat; chicken broth and pasta provide some protein. Pair a bowl with a vegetable side, such as a simple salad, to round out the meal.
Why toast the pasta?
Even browning: Stir the pasta frequently so it colours lightly rather than catching on the bottom of the pot. A little colour brings a nutty flavour to the finished soup.
Watch closely: The pasta can go from pale to too dark quickly, especially in a hot pan. Add the blended mixture as soon as it is lightly browned.
Getting a smooth tomato base
Blend well: The onion, tomatoes, garlic and first measure of broth should form a smooth mixture in about 20 seconds. If needed, scrape down the blender and briefly blend again.
Pour carefully: The tomato mixture may spit when it meets the hot oil and pasta. Pour it in steadily and keep your face and hands clear of the pot.
How to tell when it is ready
Gentle simmer: Once the remaining broth is added, bring the covered pot to a gentle boil and cook for 10 minutes. Keep the heat moderate so the soup simmers rather than bubbles vigorously.
Soft pasta: Check a few alphabet shapes before serving; they should be tender without falling apart. If they need more time, simmer briefly longer and check again.
Choosing the broth
Ready-made broth: Use chicken broth for a direct, savoury base, and taste the soup before serving in case it needs seasoning.
Bouillon and water: The recipe also allows chicken bouillon dissolved in water. Follow the bouillon's directions, as its concentration and saltiness can vary.
What to serve with it
Fresh toppings: Serve the soup warm with queso fresco or avocado slices, as suggested in the method. Add them at the table so the cheese stays distinct and the avocado keeps its shape.
A fuller meal: Pair a bowl with a simple salad or warm tortillas. Keep accompaniments mild so the tomato, garlic and toasted pasta remain the focus.
Recipe notes & tips
- Use a pot wide enough to let the pasta toast in an even layer.
- Stir frequently while browning to prevent the small pasta shapes from scorching.
- Blend the tomato mixture until smooth for an even-textured broth.
- Pour the blended mixture in carefully, as it can splutter in the hot pot.
- Check the pasta near the end of cooking, since its tenderness can vary by brand.
Variations
- Use vegetable broth: Swap in vegetable broth for a meat-free version.
- Add avocado: Top each bowl with avocado slices just before serving.
- Finish with queso fresco: Crumble the cheese over the soup at the table.
- Use bouillon: Make the broth with chicken bouillon and water according to its directions.
- Blend the tomatoes longer: Blend until completely smooth for a more uniform soup.
Common mistakes to avoid
- Leaving the pasta unattended: It can brown unevenly or scorch; stir frequently for the full toasting stage.
- Browning it too deeply: Very dark pasta may taste bitter; stop when it is lightly brown.
- Pouring too quickly: Hot oil can splutter when the tomato mixture goes in; pour carefully and steadily.
- Boiling vigorously: A rolling boil can make the small pasta shapes overly soft; keep the soup at a gentle boil.
- Skipping the doneness check: Pasta may need a little more or less time; taste a piece before serving.
How to store
Cool leftovers promptly and refrigerate in a covered container for up to 3 days. Reheat gently on the hob or in the microwave until hot, adding a splash of broth or water if the pasta has absorbed too much liquid.
Frequently asked questions
Can I make this with bouillon instead of chicken broth?
Yes. The recipe gives chicken bouillon and water as an alternative; prepare it according to the bouillon's directions.
How do I know when the alphabet pasta is cooked?
Taste a few pieces after the 10-minute simmer. They should be soft and tender; continue simmering briefly if they are still firm.
Can I prepare the tomato mixture ahead?
Yes. Blend the onion, tomatoes, garlic and the first measure of broth ahead and refrigerate it in a covered container. Use it within a day for the best freshness.
Can I use another type of pasta?
Small pasta shapes can work, but cooking times may differ from alphabet pasta. Check the packet and taste as the soup simmers.
What toppings go well with Sopa de Letras?
The method suggests queso fresco or avocado slices. Add either just before serving.
Can I freeze the soup?
You can freeze it, though the pasta may become softer after thawing. For the best texture, freeze the broth separately if possible and cook fresh pasta when serving.
