I like soup anytime... but one a chilly, cold day in Texas, when it feels like God knocked down the barbwire between Amarillo and the North Pole? Well, soup is a necessity.

I don't think you'll find anything in this ingredients list that you are unfamiliar with (if you live in the United States). I like it served with tortilla chips but a good, crusty bread to soak up any molecules of leftover broth works well, too.

• Boneless chicken keeps it easy. Use breasts or thighs - the thighs have more flavor and generally cost less.
• Fajita seasoning is all about the same. You can pick up a package or make your own with a recipe like this one from Mom on Timeout.
• Poblano peppers have a little heat but all in all they're pretty mild. If you want to take the time to roast them go ahead. It does add a smidge more flavor but it also takes more effort.
• Bell peppers are sweet once they ripen to red or yellow. I use both in this recipe because I like color.
• Onion is a requirement for good fajita anything! I use the 1015s so when I say big I mean big. You can use less if you like less onion - it's not written in blood.
• Ro*Tel tomatoes are pretty much a staple pantry ingredient here. They are diced tomatoes with chiles - you can use whatever brand you like. If you can't find them you can substitute an extra can of diced tomatoes plus a 4 ounce can of chopped chiles.
• Diced tomatoes are a big part of the flavor here. I like Cento or RedGold because they taste more like fresh tomatoes to me. Use what you like.
• Black beans are easiest to use from a can. I know they're cheaper if you used the dried ones but they never quite get the texture of canned ones. If you want to use dried black beans go for it - just make sure you really cook them well the day before.
• Ranch Style beans are a brand here in Texas. They're basically pinto beans in a chili gravy - hard to explain. You can substitute pinto beans or red beans.
• Corn can be fresh from the cob, frozen, or canned. You can use white or yellow. Whatever.
• Chicken stock has more flavor than chicken broth I think but you can use either. You could also . use V-8 or vegetable broth.
• Avocados make a delicious garnish but it's optional of course.
• Shredded cheddar sort of melts on top of the soup so every spoonful is gooey and cheesy.

FAQs

Here are the questions I am most frequently asked about this recipe.

Is chicken fajita soup spicy?

Not really - it's pretty mild. If you'd like it spicier add some jalapeno or chipotle. If you'd like it milder substitute a can of diced tomatoes for the Ro*Tel.

Does it freeze well?

Yep! You can freeze it for up to 3 months with no problems at all. Of course, leave the avocado and cheddar off of it until serving time.

What can I serve with fajita soup?

Tortilla chips or warm tortillas and butter are classic sides. A big crisp salad with some sort of creamy dressing (ie: Ranch) works well, too. Sopapillas or Tres Leches cake would be delish if you're doing dessert.

What makes it "fajita"?

Fajitas refer to any grilled meat that is served in a tortilla or taco.

They were not much more than backyard BBQ fare until 1969 when they were first served commercially as Austin street food, and seasoned a certain way.

Now anything that's seasoned that way magically becomes "fajita" whatever.

Tips

Making soup in the slow cooker is so easy and I love the fact that the house just starts smelling better and better as the day goes on.

• Use grilled skirt steak and beef stock in place of the chicken.
• Add some hominy. I love the texture it adds.
• If you like cilantro this is a great soup to add it to, either during cooking or to garnish.
• You can get fire roasted corn and it's particularly good in this dish.
• Use cojita cheese instead of the Cheddar.
• Make it creamy by adding 1 can of cream of chicken soup with the other ingredients.
• You can make it in an Instant Pot in about 10 minutes or on top of the stove in about 20.
• It's better the 2nd day.
• This soup freezes well (leave out the avocado and cheese) for up to 3 months.

If you are in need of a slow cooker I recently updated to this Crock-Pot 6-½-Quart Programmable Touchscreen Slow Cooker. It's stainless steel, heats evenly, and I just love mine. It has an automatic warming feature so that once the food is cooked it keeps it warm, and at a safe temp) until you are ready to eat.

The stainless steel finish and the touchscreen control make it  super easy to keep clean, too.
