The Full Pressure Cooker Journey
- Start heating your extra-virgin olive oil in the cooker’s skillet setting on medium. You wanna warm it up until it’s shimmering but not smoking.
- Toss in the Yukon gold potatoes with kosher salt and pepper. Stir them around now and then until they get nice and golden, tender pulling easily with a fork. About 15 minutes, so be patient.
- Butter goes in next along with chopped shallot and minced garlic. You stir this mix until shallots turn translucent and smell dang good, around 3 minutes. That’s where your flavor base shines.
- Next, add heavy cream and your chicken or fish stock. Give it a good stir so everything’s mixed.
- Throw in those rosemary sprigs and lower heat to a simmer. Let that sauce thicken a bit, probably around 5 minutes. You gotta watch it so it doesn’t burn, just get right consistency.
- Lay the cod fillets gently in the skillet, spoon sauce over them, and cover. Now it’s time for the pressure cooker job. Cook until the fish is opaque and flakes easily when you poke, about 8 to 10 minutes. That quick release? Use it to stop cooking just right.
- Serve it piping hot with potatoes and sauce spooned on. Sprinkle minced parsley if you want a fresh pop of color and flavor.

Easy Tweaks That Make Life Simple
- If you’re short on time, use pre-chopped shallots and minced garlic from the jar. Saves chopping fuss.
- Swap chicken stock with vegetable broth if you’re feeling plant-based vibes, still tasty real good.
- Throw the cod in frozen but add a couple extra minutes to cooking time, just watch your quick release carefully so it don’t overcook.
These small shortcuts keep you on track without losing that dang delicious flavor. Sometimes you just need fast and easy without skimping on taste, you know?

How to Store This for Later
- Refrigerate in an airtight container and eat within 2 days for best flavor and texture. Reheat gently on low heat to keep the cream sauce from splitting.
- Freeze cooked cod and potatoes separately if possible, each in sealed bags or containers. Fish can get a little tough if frozen after cooking, so freezing raw cod is better if you plan ahead.
- Leftovers make great next-day meals. When reheating, add a splash of stock or cream to loosen the sauce and warm slowly to keep things tender.
The FAQ Section You Actually Need
- Can I use other fish besides cod? Sure, tilapia or haddock work real good; just adjust cooking times a bit.
- What if I don’t have fresh rosemary? Dried rosemary can step in but add it earlier so it softens and flavors the sauce well.
- Is it okay to use frozen potatoes? Fresh Yukon golds are best, but frozen can do in a pinch; they might get softer faster so watch cooking closely.
- How do I know when the cod is done? It flakes easily when poked with a fork and looks opaque throughout.
- Can I make this recipe dairy-free? Swap heavy cream and butter for coconut milk and olive oil, though it’ll shift the sauce flavor.
- What’s a quick release, and why is it important here? Quick release is when you release the steam fast from the cooker to stop cooking right away. This helps keep the fish tender and prevents potatoes from getting mushy.
