Ingredients

For the Meatballs

• 1 lb Lean Ground Beef
• ½ cup Chopped Fresh Cilantro
• 1 large Egg
• 1 tsp Salt
• ½ tsp Black Pepper
• 1 tsp Ground Cumin (divided)
• ¼ tsp Cayenne Pepper (optional)

For the Soup Base

• 2 Tbsp Extra Virgin Olive Oil
• 1 Medium Onion, chopped
• 1 large Garlic Clove, minced
• 1 Celery Stalk, chopped into small chunks
• 8 cups Chicken Stock or Beef Stock (low-sodium preferred)
• 4 cups Water
• ½ cup Tomato Sauce
• 1 tsp Dried Oregano
• 1 lb Fresh Green Beans, trimmed and cut into pieces
• For Garnish: Fresh Lime Wedges, Chopped Cilantro

Instructions (Stovetop Method)

1. Prep Soup Base: In a large pot or Dutch oven, heat the olive oil over medium heat. Add the chopped onion and celery and cook until tender (about 3 minutes). Add the minced garlic and ½ teaspoon of cumin (reserved from the meatball seasoning) and cook for 1 minute more.
2. Add Broth: Add the stock, water, tomato sauce, and oregano to the pot. Bring the liquid to a boil, then reduce the heat to a simmer. Add the green beans.
3. Make Meatballs: In a large bowl, combine the ground beef, chopped cilantro, egg, remaining ½ teaspoon of cumin, salt, black pepper, and cayenne (if using). Use your hands to mix gently, avoiding overmixing. Shape the mixture into 1-inch meatballs (about 20–25 meatballs).
4. Simmer Meatballs: Gently drop the meatballs into the simmering soup, one at a time. Cover the pot and simmer for 30 minutes, or until the meatballs are cooked through and the vegetables are tender.
5. Serve: Adjust seasoning with salt and pepper. Ladle into bowls and serve immediately, topped with fresh chopped cilantro and a squeeze of fresh lime juice.

Storage and Expert Tips

• Meatball Size: Keep the meatballs uniform in size (1 inch) to ensure they all cook through simultaneously during the 30 minute soup recipe time.
• Simmering Temperature: Maintain a gentle simmer, not a rolling boil, which prevents the meatballs from breaking apart or becoming tough.
• Cilantro is Key: Cilantro is the traditional herb in authentic Albondigas and provides a crucial fresh, savory flavor to the meatballs.
• Serving: This soup is delicious served with fresh lime juice squeezed over the top—the acid brightens the tomato base beautifully.

Variations

• Traditional Albondigas: For a classic, non-keto version, mix ¼ cup of cooked white rice into the meatball mixture.
• Hearty Veggies: Add 1 cup of chopped carrots, diced zucchini, or chopped potatoes (non-keto) along with the broth (Step 2).
• Spice Boost: Add 1 can of diced fire-roasted tomatoes and green chilies (drained) instead of the plain tomato sauce.

Frequently Asked Questions

Q: Can I use this low carb meatball soup recipe with ground turkey or chicken? A: Yes. You can substitute ground turkey or chicken for the beef. The meatballs may be slightly more delicate, so handle them gently when dropping them into the broth.

Q: Can I freeze the Mexican Meatball Soup? A: Yes! This Mexican meatball soup freezes very well. Cool completely, then freeze in an airtight container for up to 3 months. Thaw overnight and reheat gently on the stovetop.

Q: Do I need to brown the meatballs before adding them to the soup? A: No. The traditional Albondigas method is to simmer the raw meatballs directly in the broth. This ensures the meatballs stay moist and infuse the soup with savory flavor.

Q: How do I prevent the meatballs from falling apart in the broth? A: The egg in the mixture acts as the binder. Ensure you do not overmix the beef mixture (mix only until just combined), and maintain a gentle simmer rather than a rolling boil, which can cause the meatballs to break apart.
