With smoky roasted poblanos juicy chicken and loads of melty cheese this soup is comfort food with a spicy Mexican kick that also fits beautifully into a low carb lifestyle.

The first time I made this on a rainy weekend it instantly became a comfort food staple. Now it is a go-to for weeknight dinners and cozy Sunday lunches.
Ingredients
- Poblano peppers: Roasting brings out their smoky mild spice Select firm dark green poblanos without soft spots
- Chopped onion: Adds sweetness and depth Look for onions that feel heavy for their size and no sprouting
- Garlic: Finely minced for bold flavor Fresh cloves are best
- Ground cumin: Essential for warm earthy Mexican notes Choose freshly ground for maximum aroma
- Salt and pepper: Balances and enhances all the flavors Freshly cracked black pepper lifts everything
- Butter: Creates a rich luxurious base Unsalted butter gives you control over seasoning
- Cream cheese: Gives body creaminess and a slight tang Full fat cream cheese melts best
- Shredded cheddar cheese: Adds sharp flavor and stretches beautifully
- Slices of cheddar or pepper jack cheese: Melts to form a gooey golden topping Try to pick freshly sliced cheese from the deli counter
- Boneless skinless chicken thighs or breasts: Juicy tender protein pieces Chicken thighs stay more moist but chicken breasts work just as well Choose organic or free range if possible

Step-by-Step Instructions
- Roast the Poblanos:
- Place poblano peppers under the broiler or directly on a gas flame until the skins char and blister Turn the peppers as needed so the entire skin blisters evenly This brings out sweetness and smoky flavor
- Steam and Peel Peppers:
- Transfer roasted peppers to a bowl and cover so they steam for about ten minutes This loosens the skins making peeling easier
- Prepare Peppers:
- Gently peel off as much charred skin as possible Remove stems and seeds Place the skinned peppers in a blender or food processor and pulse until they are finely chopped The texture should be spreadable but not a puree
- Sauté the Aromatics:
- Melt butter in a large saucepan over medium heat Add chopped onion and cook until translucent about five minutes Stir often to prevent browning Add garlic ground cumin and chopped roasted poblanos Sauté for one minute to bloom the spices and infuse the oil with flavor
- Simmer the Soup Base:
- Pour in chicken bone broth and season with salt and pepper Bring the mixture to a gentle boil then lower the heat to a simmer
- Cook the Chicken:
- Add chicken pieces to the simmering soup Cook for about ten minutes until the chicken is tender and fully cooked The chicken should be opaque and firm
- Blend the Cheeses:
- Combine cream cheese and shredded cheddar in a blender or food processor with one cup of hot broth Blend until silky smooth to help the cheeses melt into the soup without lumps
- Finish the Soup:
- Return the cheese mixture to the pot Stir well and let the soup simmer gently for a few more minutes The broth will turn creamy and rich Taste and adjust salt and pepper as desired
- Broil the Cheese Topping:
- Ladle soup into ovenproof bowls Top each with a slice of cheddar or pepper jack Arrange the bowls on a baking sheet and set under a broiler for about one to two minutes until the cheese melts and bubbles Watch closely to prevent burning
- Serve:
- Sprinkle with fresh herbs like chopped cilantro or green onions for color and brightness Serve piping hot

The roasted poblanos are my hands down favorite ingredient They remind me of homemade chile rellenos made by my grandmother on fiesta days Inspired by her I first charred my peppers over the open flame and it is impossible to beat the flavor
