Easy Keto Chicken Tortilla Soup Recipe

Chicken tortilla soup is a comfort food classic—but most versions are loaded with flour tortillas, corn, black beans, and sugar in the broth. When you’re on keto, ordering it at a restaurant means deviating from your macros or eating a modified version that tastes disappointing.

This keto chicken tortilla soup solves that problem. It’s creamy, packed with chicken and vegetables, loaded with crispy toppings, and has just 5g net carbs per serving. It tastes like the real deal, freezes beautifully, and comes together in under 45 minutes.

Why This Soup is Perfect for Keto

Traditional tortilla soup gets its carbs from tortilla strips, beans, corn, and sugar-laden broths. This version replaces those high-carb ingredients with keto-friendly alternatives that taste just as good.

• High in protein: 28g per serving keeps you full for hours
• Creamy texture: From heavy cream and cheese, not cornstarch
• Restaurant-quality flavor: No compromise on taste
• Freezer-friendly: Make a big batch and meal prep for the week
• Under 5g net carbs: Stay in ketosis without tracking extensively

Ingredients

For the Soup Base:

• 2 tablespoons butter
• 1 medium onion, diced
• 4 cloves garlic, minced
• 8 cups chicken broth (low-sodium)
• 2 cups heavy cream
• 1 pound boneless, skinless chicken breasts
• 1 cup diced bell peppers (any color)
• 2 cups diced zucchini (or celery for more texture)
• 1 tablespoon cumin
• 1 tablespoon chili powder
• 1 teaspoon paprika
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• Juice of 1 lime
• 1/2 cup shredded cheddar cheese (optional, adds 1g carb per serving)

For Crispy Tortilla-Style Topping:

• 2 low-carb tortillas (or 4 thin slices of cheese), sliced into strips
• Oil for frying
• Salt to taste

Optional Toppings:

• Sour cream
• Avocado slices
• Fresh cilantro
• Jalapeño slices
• Crispy bacon bits
• Shredded cheddar cheese

Step-by-Step Instructions

Step 1: Sauté Aromatics (5 minutes)

Heat butter in a large pot or Dutch oven over medium heat. Add diced onion and sauté for 3-4 minutes until softened. Add minced garlic and cook for another minute until fragrant.

Step 2: Add Broth and Spices (2 minutes)

Pour in the chicken broth and add cumin, chili powder, paprika, salt, and pepper. Stir well to combine. Bring to a gentle simmer.

Step 3: Cook Chicken (15 minutes)

Add the chicken breasts to the simmering broth. Cook until internal temperature reaches 165°F (about 15 minutes). Remove chicken with a slotted spoon and set aside on a cutting board.

Step 4: Add Vegetables (10 minutes)

Add diced bell peppers and zucchini to the pot. Simmer for 8-10 minutes until vegetables are tender.

Step 5: Shred Chicken and Add Cream (5 minutes)

Shred the cooked chicken using two forks. Return shredded chicken to the pot. Stir in heavy cream and lime juice. Add cheese if desired. Taste and adjust seasonings.

Step 6: Make Crispy Topping (5 minutes)

While soup simmers, heat oil in a skillet over medium-high heat. Cut low-carb tortillas into strips and fry until golden and crispy (about 3-4 minutes). Drain on paper towels and sprinkle with salt.

Alternatively, slice cheese into thin rectangles and bake at 400°F for 5 minutes for a crispy cheese “tortilla” topping.

Step 7: Serve and Top

Ladle soup into bowls. Top with crispy tortilla strips, sour cream, avocado, cilantro, and jalapeños. Serve hot.

Pro Tips & Variations

Use an Instant Pot

Set to high pressure, add all ingredients (except heavy cream), and cook for 10 minutes. Release pressure naturally, then stir in heavy cream.

Slow Cooker Version

Combine all ingredients except cream in slow cooker. Cook on low for 6-8 hours. Stir in cream during the last 30 minutes.

Add Jalapeños for Extra Heat

Dice and add 2-3 jalapeños with the other vegetables. Adjust amount based on your heat preference.

Make it Spicier

Increase chili powder to 1.5 tablespoons and add 1/2 teaspoon cayenne pepper.

Add Bacon

Crisp up 4-6 bacon slices, chop them, and stir into the soup. Adds 0 carbs and incredible flavor.

Use Rotisserie Chicken

For even faster prep, shred 2 cups of rotisserie chicken and skip the cooking step. Just add directly to the broth.

Storage & Freezing

Refrigerator

Store in an airtight container for up to 4 days. The tortilla strips will get soggy—store separately and crisp them up when reheating.

Freezer

This soup freezes beautifully for up to 3 months. Cool completely, portion into freezer bags or containers, and label with the date. Thaw overnight in the refrigerator and reheat over low heat on the stove.

Make-Ahead Prep

You can prep all vegetables the night before, store in containers, and assemble in 30 minutes when you’re ready to cook.

Can I use bone broth instead of chicken broth?

Absolutely. Bone broth adds even more nutrition and a richer flavor. Use it in a 1:1 ratio.

What if I don’t have low-carb tortillas?

Skip the tortilla strips entirely, or make crispy cheese strips by baking thin cheddar slices. You can also use thinly fried zucchini chips as a crunchy topper.

Is this soup dairy-free?

Not as written. To make it dairy-free, replace heavy cream with coconut milk or a dairy-free cream alternative. The flavor will be slightly different but still delicious.

How many servings does this make?

This recipe yields 6 servings. You can easily double it and freeze half.

Can I add other vegetables?

Yes! Spinach, kale, diced tomatoes (in moderation), or mushrooms all work well. Just account for additional carbs.

Is this soup spicy?

It has a mild to moderate level of spice from chili powder. Adjust the amount to your preference or add jalapeños for extra heat.
