The Complete Shopping Rundown
You gotta hit the store with your list ready for this soup. First up is 1 pound smoked sausage, sliced just right for that smoky flavor kick. Olive oil is a must for cooking - grab a tablespoon to get that pan sizzling.
Don't forget a medium onion, diced up fine, and 3 cloves garlic minced fresh to bring out awesome aromatics. Chicken stock sets the broth depth, so you need 4 cups of that good stuff.

Potatoes gotta be russet and peeled, diced into chunks about 3 medium sized ones. Brussels sprouts come in 2 cups, trimmed and halved so they cook evenly. Rounded off with ½ teaspoon dried thyme, ½ black pepper, and a pinch of salt to taste. That's your full shopping lineup.
Your Complete Cooking Timeline
Step one, heat your olive oil in the pressure cooker on medium heat. This gonna get things started with a nice sizzle. When it's warm, throw in your sliced sausage and brown 'em up, about 5 minutes till you see a nice crust.
Next, stir in your diced onion and cook till they turn translucent, roughly 3 minutes. Add your garlic next and let it cook for 1 more minute, the smells already making you hungry. Pour in the chicken stock and let it come to a boil so all the flavors start mixing.
Add your diced potatoes, Brussels sprouts, thyme, and black pepper straight into the cooker. Seal it up, make sure that sealing ring is set good. Time to pressure build - cook it on high pressure for about 8 minutes.
When the time's up, use slow release to let the pressure come down gently. This keeps the veggies from turning mushy. Open the lid, stir carefully, and check if potatoes and sprouts are tender. If not, give it a couple more minutes without pressure, simmering inside.

Finally, season your soup with salt to your taste. Serve it hot, maybe with some crusty bread if you like. Total time from start to spoon is about 1 hour 40 minutes, including prep and simmer time before pressure cooking.
Easy Tweaks That Make Life Simple
If you're short on time, slice your sausage ahead and store it in the fridge. That way you're ready to go fast when the cooker calls. You can swap russet potatoes for Yukon gold if that's what you got, keeps the texture nice.
Using pre-chopped frozen Brussels sprouts works real good too. Just toss 'em in frozen, no need to thaw first. And when you're done, do a quick release for a little more kick in your broth, adds a sharp punch.
The Flavor Experience Waiting for You
This soup's got a rich smoky base thanks to the sausage, which fills the broth with deep warm flavors. When you dig your spoon in, you taste chunks of soft potatoes soaking up all that goodness. Brussels sprouts add a slight bite and some earthiness, balancing things out.
The thyme and black pepper are subtle but pull everything together so it doesn't feel heavy. You notice the garlic and onion float in the background, giving it a warmth that stays with you long after the bowl's empty. It's like a hug in soup form.
When it's hot and steaming, every smell and taste really pops. You remember this kinda meal when the weather's cool and you want something that feels both hearty and fresh. It's a simple recipe but full of comfort.
How to Store This for Later
Once your soup cools down, put it in airtight containers that seal good. Fridge time is usually safe for about 3 to 4 days. You can also freeze the soup for longer keeping the flavors intact if you label it with the date.
For reheating, you can use the stovetop or microwave until it's steaming hot again. When defrosting frozen soup, best to do it overnight in the fridge so it heats evenly. Always remember to check the sealing ring on your cooker if you wanna reheat and add a little broth if it seems thick.
Everything Else You Wondered About
Q1: Can I use a quick release instead of slow release? Yeah, you can but quick release might make your veggies a bit less tender. Slow release keeps 'em perfect.
Q2: What if I don't have smoked sausage? Use any sausage you like but smoked adds that special depth to broth. Regular sausage works too just maybe less smoky flavor.
Q3: Can I add other veggies? For sure! Carrots or celery go great with this soup, just adjust cooking time if needed.
Q4: What's the sealing ring good for? It keeps steam from escaping and helps pressure build so your cooking is right on point.
Q5: Is it okay to brown sausage right in the pressure cooker? Yep, it saves dishes and adds flavor right there before you lock the lid on.
Q6: Can I make this recipe vegan? You could swap sausage with a plant-based option and use vegetable stock instead of chicken. It works pretty well!
