The Complete Shopping Rundown

2 tablespoons olive oil for that rich base flavor.
1 medium yellow onion, diced small — kinda your flavor foundation.
Green and red bell peppers, diced — you want about 1 to 1 ¼ cups each for color and sweetness.
1 medium jalapeño, diced — take out the seeds if you want less heat or add 'em for more kick.
3 cloves garlic, minced — gotta have that zing to bring the spices alive.
Andouille sausage, 12 ounces, sliced thin — this stuff brings the Cajun vibe into the soup.
Yukon gold potatoes, about 1 pound diced — these hold up nice and creamy after pressure cooking.
32 ounces chicken broth — low sodium helps you control salt and keep it tasty.

You also want smoked paprika, Old Bay or Cajun seasoning with salt, black pepper, heavy cream, and a handful of fresh chives for garnish if you’re feeling fancy. All these bits mix to give you that perfect blend of heat, creaminess, and smoky layers. Once you got them all, you’re ready to cook.

Walking Through Every Single Move

Step one: Heat olive oil in your pressure cooker using the sauté setting or your stove if it doesn’t have that feature. Let it get nice and warm.

Next, toss in your diced onion, green and red bell peppers, plus your jalapeño. Keep stirring for about 5 or 6 minutes till they’re soft and smelling sweet.

Now add in garlic, Old Bay or Cajun seasoning, smoked paprika, and black pepper. Cook it all just a minute so the spices open up and get fragrant.

Throw the sliced andouille sausage into the pot. Brown it up for 5 to 6 minutes. You want those edges crisped for flavor.

Pour in the chicken broth and give everything a little stir. Time to get that float valve doing its job as you seal the lid and set the cooker to high pressure.

Add your diced potatoes on top (don’t stir after adding them), seal the cooker, and wait for pressure build. Once it’s at high pressure, cook for 8 minutes.

When done, go for a quick release to stop the cooking quick. Open the lid carefully — sealing ring might still be warm.

Stir in the heavy cream and let the soup simmer uncovered for 5 minutes so it thickens up just right. Taste it, adjust seasonings if needed, then scoop into bowls and top with fresh chives if you got 'em.

Time Savers That Actually Work

Use pre-diced frozen peppers and jalapeño to save chopping time.
Buy pre-minced garlic in a jar if you want to skip peeling cloves.
Slice your sausage while the veggies cook so you don’t waste any time.
Set your pressure cooker on sauté right away so it’s warm by the time you finish chopping.

These little shortcuts help you get this soup from start to bowl without feeling rushed or stressed. You’re still controlling flavor, just speeding up the boring parts.

The Flavor Experience Waiting for You

How to Store This for Later

Cool your soup completely before moving it to storage containers. If you keep it in the fridge, it lasts about 3 to 4 days and tastes just fine reheated gently on the stove or microwave.

For longer, pour it in airtight containers and freeze. It freezes great and you can thaw it overnight in the fridge or pop it in a pot over low heat to warm slow and even.

If you know you want leftovers when dinner’s done, divide your soup into single-serving containers so you can take out just what you need. It cuts down on waste and reheats super fast.

What People Always Ask Me

Can I make this soup vegetarian? Sure, swap out the andouille sausage for smoked tofu or a veggie sausage and use veggie broth instead of chicken broth.
How spicy is this soup? It’s got a nice medium heat from the jalapeño plus the Cajun seasoning. You can take out seeds or reduce jalapeño to make it milder.
What if my pressure cooker doesn’t have a quick release? If it only has slow release, just give it extra time to release naturally and be patient opening the lid.
Can I add other veggies? Definitely toss in corn, celery, or even some chopped tomatoes if you want more layers.
Do I have to use Yukon gold potatoes? They’re best because they hold shape well, but russets or red potatoes work too just be ready for slightly different texture.
What’s the best way to thicken the soup if it’s too watery? Simmer uncovered a little longer after adding cream to reduce it down. Or mash a few potatoes in the pot for extra creaminess.
