CPK Tortilla Soup Recipe: California Pizza Kitchen’s Spiced Broth

This soup captures the vibrant flavors of California Pizza Kitchen‘s signature dish in your own kitchen. I’ve recreated their spiced broth through careful testing, ensuring it delivers the same depth of flavor.

The secret lies in building layers of taste with charred vegetables, aromatic spices, and a touch of lime. Each ingredient plays a crucial role in achieving that authentic restaurant quality at home.

What results is a rich, complex broth filled with tender chicken, crisp tortilla strips, and fresh toppings. The balance of smoky, spicy, and tangy notes makes every spoonful satisfying.

Serve with avocado, cheese, and cilantro for the complete experience. Here’s how to make this restaurant favorite.

The charring step is non-negotiable here. Use ripe Roma tomatoes and fresh poblanos—they should blacken in spots but not burn to ash. Most supermarkets carry poblanos year-round, but Latin markets often have better selection. For the chilis, Guajillo gives that authentic CPK depth (find them in the Mexican aisle or Penzeys online). Don’t skip toasting the cumin—it wakes up the flavor.

No Guajillo chilis? Ancho chilis work in a pinch, or add 1 tsp cayenne for heat. Swap the fire-roasted tomatoes for regular crushed tomatoes plus 1 tsp liquid smoke. For a vegetarian version, use extra-firm tofu instead of chicken (press it first). The tortilla strips can be baked instead of fried—400°F for 8-10 minutes until crisp.

Broth base keeps 4-5 days refrigerated, but add toppings fresh. Freeze portions for 3 months—leave room for expansion. Charred veggies can be prepped a day ahead (store unpeeled garlic with them). The lime juice is best added fresh, so wait until serving.

Step-by-Step Instructions for CPK Tortilla Soup

Here’s my proven method for building layers of smoky, tangy flavor in this classic soup.

Step 1: Char the Vegetables for Depth

Heat the 2 tbsp vegetable oil in a large pot over medium-high heat. I add the 1 whole yellow onion (quartered), 4 whole Roma tomatoes (halved), 2 whole poblano peppers (quartered), and 6 cloves garlic cloves (unpeeled) to the pot. You want to char them until they develop deep black spots—this usually takes 8-10 minutes.

Don’t stir too frequently; let the vegetables sit long enough to develop those beautiful char marks. The garlic will soften inside its skin, and the peppers will blister. This charring step is crucial—it adds that signature smoky depth to the broth.

Step 2: Toast the Spices and Build the Base

While the vegetables char, I toast the 2 whole dried guajillo chili in a dry skillet over medium heat for 30 seconds per side until fragrant. Then I add them to the pot along with the 2 tsp ground cumin, 1 tsp smoked paprika, 1 tsp dried oregano, and 2 whole bay leaves.

Stir everything together and cook for 1-2 minutes until the spices become aromatic. This blooms their flavors before the liquid goes in. Then pour in the 8 cups chicken broth and 1 can fire-roasted crushed tomatoes, scraping up any browned bits from the bottom of the pot.

Step 3: Simmer and Shred the Chicken

Add the 1 lb boneless skinless chicken breasts to the pot and bring to a boil. Once boiling, reduce heat to medium-low and let it simmer for 15-20 minutes until the chicken is cooked through and tender. You’ll know it’s done when it shreds easily with a fork.

Remove the chicken from the pot and shred it using two forks. I return the shredded chicken to the soup at this point so it absorbs all those amazing flavors as it continues to simmer. The broth should be rich and fragrant, with the vegetables softened and breaking apart.

Step 4: Finish with Lime and Tortilla Strips

Stir in the 0.25 cup lime juice and season with salt to taste. The lime brightens all the flavors and balances the smokiness. While the soup simmers, I cut the 4 whole corn tortillas into thin strips.

Heat a thin layer of oil in a skillet over medium-high heat and fry the tortilla strips in batches until they’re golden and crisp, about 2-3 minutes per batch. Drain them on a paper towel-lined plate. Serve the soup hot, topped with the crispy tortilla strips for that perfect CPK crunch in every spoonful.

Make-Ahead Tips for This Dish

Broth Base Prep

You can make the broth base 2-3 days ahead and store it in the fridge. I use airtight glass containers—they preserve flavors better than plastic. The charred vegetables infuse the broth with deeper flavor as it rests overnight. 💡

Tortilla Strips

Fry the tortilla strips the day of serving—they lose crispness quickly. If you must prep ahead, store them in a paper bag at room temperature for up to 8 hours. Re-crisp in a 350°F oven for 5 minutes before serving.

Chicken Handling

Cook and shred the chicken separately, then store in the fridge for up to 2 days. I keep it in a sealed container with a little broth to maintain moisture. Add it to the reheated soup just before serving to prevent overcooking.

Freezing Tips

This soup freezes beautifully for up to 3 months. Cool completely before portioning into quart-sized freezer bags. Leave 1 inch headspace for expansion. Thaw overnight in the fridge before reheating. ❄️

Lime and Toppings

Add lime juice and fresh toppings like avocado or cilantro only when serving. The lime loses its brightness if added too early, and toppings get soggy. I prep all garnishes fresh the day I plan to serve. 🍋

Reheating Method

Reheat gently over medium-low heat for 10-15 minutes. If the soup is too thick after storage, thin it with ½ cup water or broth. Stir occasionally to prevent sticking and taste for seasoning adjustments.
