ingredients required to cook slow cooker spanish chicken stew

Recipe inspiration

When creating this recipe, I was going through an obsession with one of Spain's most popular recipes: paella. Paella involves cooking rice in a mixture of broth, and spices (including saffron), and is traditionally topped with rabbit or chicken (1). The version that I cooked also included smoked paprika, peas, roasted red peppers, tomatoes and seafood (2).

Taking inspiration from the flavors I loved in paella, as well as spices traditionally found in Spanish kitchens (3), I came up with this stew; it is not meant in any way to be authentic. For an authentic recipe, check out this Spanish chicken and chorizo stew!

Ingredient notes

chicken- we are using boneless skinless chicken thighs for this recipe. If you swap for chicken breasts, you'll need to reduce the cook time to 4 hours on low (make sure the potatoes are cooked through!)
potatoes- ruby, yellow or even purple baby potatoes work great in this recipe: cut them in half if you are cooking fresh, leave them whole if you are assembling as a crockpot freezer meal
roasted red peppers- usually near olives in the condiment aisle. You could also check the canned vegetable section. Drain and chop them up.
smoked paprika- a spice often used in Spanish cuisine, it has a much more potent flavor than sweet paprika. It adds a subtle smokiness to this stew. Find it with the spices, or purchase on Amazon.
saffron threads- saffron is the world's most expensive spice, but don't let that deter you from cooking with it; a little goes a long way! Adding a pinch of saffron threads to this stew is sufficient to infuse the whole pot with delicious flavor. Purchase a good brand (one that you know), as you get what you pay for.
balsamic vinegar- adding acid to the stew after a long cook time helps brighten and revive the flavors.

Recipe tips

Low and slow

When using the slow cooker, I like to use the low setting whenever possible. The reason for this is that some slow cookers cook quite hot, and on high, they can vigorously boil and overcook the protein. For this slow cooker Spanish chicken stew, we are cooking on low for 5 hours. At this point, the chicken should be fall-apart-tender, and the potatoes should also be cooked through.

Remember not to peek at your stew while it simmers, as this can add up to an hour onto your cook time!

Last minute add-ins

Just before serving your stew, stir in 1 tablespoon of balsamic vinegar, and 1 cup of frozen peas. We add the vinegar to help brighten the flavors back up after the long cook time, and we add the peas because they will overcook if added at the start.

To thicken or not to thicken

Unlike the Tuscan chicken stew on this website, this stew recipe is not thickened. If you really love a thickened stew, then you can add in a mixture of 2 tablespoons cornstarch + ¼ cup water to the slow cooker 30 minutes before serving. Turn the slow cooker to high, and simmer until thickened.

Serve it up!

After cooking the stew through, sprinkle with fresh chopped parsley, and serve it up! With a source of protein, vegetables and carbohydrates, we consider this to be a complete meal, however it is great served with a rustic loaf of sourdough bread for dunking.

Serving size + equipment

This recipe should be cooked in a larger slow cooker- 5 or 6 quarts. If you are looking to cut the recipe in half, you'll need to cook in a 2.5 or smaller slow cooker.

Storage + Meal Prep

Slow cooker Spanish chicken stew works really well for meal prep. Here are two ways you can do it:

Crockpot freezer meal

A crock pot freezer meal is assembled ahead and frozen before cooking. This way, when it's time to cook, you simply dump the ingredients into the slow cooker and skip any measuring. This is a great recipe to prepare for someone who is expecting a baby.

Assemble all stew ingredients except for the balsamic vinegar and peas in a sturdy gallon-sized freezer bag or large meal prep container (*make sure you leave the potatoes whole!). You can leave out the stock as well if the bag/container is too full.
Squeeze out as much air as you can and freeze it flat.
Freeze for up to 3 months; thaw completely, then cook as directed in the recipe card below.

*if potatoes are cut in half, they can turn brown and get a weird texture

Reheat meals

Cook the stew through, then store in an air tight container in the fridge (4 days) or freezer (3 months).

To reheat, dump the stew into a pot and heat on medium heat, stirring occasionally. Heat until steaming hot, and enjoy!
