Creamy Poblano Chicken Rellenos Soup

Creamy Poblano Chicken Relleno Soup takes the beloved flavors of chiles rellenos, one of Mexico’s most iconic dishes, and turns them into a rich, velvety, spoonable comfort food. Traditional chiles rellenos, which originated in Puebla, Mexico, feature roasted poblano peppers stuffed with cheese, coated in a fluffy egg batter, and fried until golden.

They’re delicious but time-consuming to make. This soup captures that same smoky, cheesy, gently spicy magic in a single pot, with far less effort.

The soup begins with a classic roux: onion, jalapeño, and plenty of garlic are sautéed in butter, then cooked slowly with flour until golden and nutty, building a rich, thick base. Chicken broth and half-and-half are whisked in, along with a full block of cream cheese that melts into a silky, luxurious texture. Roasted poblano peppers bring the soup’s signature smoky, earthy flavor and mild heat, while tender shredded chicken makes it hearty and satisfying. The result is creamy, comforting, and deeply flavorful, like a bowl of chiles rellenos you can eat with a spoon, ready in about 45 minutes.

Key Ingredients

Poblano peppers: The star of the soup. Roasted poblanos have a smoky, earthy, slightly sweet flavor with mild heat, giving the soup its chile relleno character.

Butter: Forms the base of the roux and adds rich, savory flavor.

Onion: Adds sweetness and savory depth.

Garlic: Brings bold, aromatic flavor. Feel free to add even more if you love garlic.

Jalapeño: Adds fresh, bright heat. Remove the seeds and ribs for a milder soup.

Flour: Cooked with butter to form a roux, which thickens the soup into a smooth, creamy consistency.

Chicken broth: Provides a savory base and balances the richness.

Half-and-half: Adds creaminess and body without being as heavy as heavy cream.

Cream cheese: Melts into the soup, making it ultra-rich, velvety, and slightly tangy, similar to the cheesy filling in chiles rellenos.

Chicken breast: Adds lean protein and heartiness. Rotisserie chicken is a quick, flavorful shortcut.

Salt and black pepper: Season and balance the flavors.

Expert Tips

Roast the poblanos well: Char them over a gas flame, under the broiler, or on a grill until blistered and blackened all over.

Steam before peeling: Place hot roasted peppers in a covered bowl or sealed bag for 10–15 minutes to loosen the skins.

Don’t rinse the peppers: Rinsing washes away the smoky flavor. Peel them by hand or with a paper towel.

Wear gloves: Jalapeños and occasionally poblanos can irritate skin and eyes.

Cook the roux slowly: Stir often over medium-low heat so it turns golden without burning.

Add broth gradually: Whisk it in slowly to prevent lumps.

Soften the cream cheese: Room-temperature, cubed cream cheese melts more smoothly.

Keep the heat gentle: Avoid boiling after adding dairy to prevent separation.

Blend part of the soup: For a smoother texture, blend half the soup with an immersion blender before adding the chicken.

Season the chicken well: Use cumin, chili powder, garlic powder, salt, and pepper for extra flavor.

Add cheese for extra richness: Stir in shredded Monterey Jack or pepper jack for a cheesier, more relleno-like soup.

Finish with lime: A squeeze of fresh lime brightens the rich flavors.

Ingredients

Butter: about 4 tablespoons

Onion: 1, chopped

Garlic: 6 or more cloves, chopped

Jalapeño: 1, seeded and diced

All-purpose flour: ½ cup

Poblano peppers: 4, roasted, peeled, seeded, and chopped

Chicken broth: 2 cups

Half-and-half: 2 cups

Cream cheese: 1 block (8 oz), softened and cubed

Chicken breast: 1, seasoned, cooked, and shredded

Instructions

1. Cook the aromatics.

Melt the butter in a soup pot over medium heat.

Add the onion and jalapeño and cook until softened, then stir in the garlic and cook for a few minutes more, until fragrant.

2. Make the roux.

Sprinkle the flour over the vegetables and stir until combined.

Lower the heat and cook, stirring often, for about 10–15 minutes so the flour loses its raw taste and turns lightly golden.

3. Build the soup.

Slowly whisk in the chicken broth to keep the roux smooth, then add the half-and-half, cream cheese, and chopped poblanos.

Let the soup cook gently over low to medium-low heat, stirring now and then, until the cream cheese melts completely.

4. Add the chicken.

While the soup simmers, shred the cooked chicken.

Stir it into the pot.

5. Heat through and serve.

Keep cooking gently until the soup is hot and just starting to bubble around the edges.

Season with salt and pepper to taste.

Ladle into bowls and enjoy this easy, creamy, delicious soup!

Tip: Keep the heat gentle once the dairy is added, since a hard boil can cause the soup to separate.

Important Notes When Making Creamy Poblano Chicken Rellenos Soup

Don’t boil after adding dairy: High heat can cause the half-and-half and cream cheese to separate.

Smart FAQs About This Recipe

What makes this a “relleno” soup?
It’s inspired by chiles rellenos, roasted poblano peppers stuffed with cheese. The soup combines roasted poblanos with creamy cheese for the same smoky, cheesy flavor.

Is this soup spicy?
It’s mildly spicy. Poblanos and a seeded jalapeño add gentle warmth. Leave in the jalapeño seeds or add another pepper for more heat.

Can I use canned green chiles instead of poblanos?
Yes, as a shortcut. Use about two 7-oz cans of diced green chiles. The flavor will be milder and less smoky than roasted poblanos.

Can I add more chicken?
Absolutely. Use 2 chicken breasts or 3–4 cups of shredded rotisserie chicken for a heartier soup.

Can I make it lighter?
Yes. Use light cream cheese, whole milk instead of half-and-half, less butter, and low-sodium broth.

Why cook the roux so long?
Cooking the flour slowly removes its raw taste and gives the soup a deeper, nuttier flavor. Stir often and keep the heat moderate to prevent burning.

Why did my soup separate?
The soup may have boiled after the dairy was added. Keep the heat low and stir gently.

How do I make it thicker or thinner?
For a thicker soup, simmer gently a bit longer or add more cream cheese. For a thinner soup, stir in more broth or milk.

Can I make it in a slow cooker?
Yes. Make the roux on the stovetop, then add everything except the chicken to the slow cooker and cook on low for 3–4 hours. Stir in the chicken during the last 30 minutes.

Can I make it ahead of time?
Yes. Make it up to 2 days ahead and refrigerate. Reheat gently over low heat, stirring and adding broth or milk to restore its creamy texture.
