Your Complete Cooking Timeline

Step 1: Heat 3 tablespoons olive oil in a large skillet over medium heat. Toss in your Yukon gold potatoes seasoned with 1 teaspoon kosher salt and pepper. Stir occasionally until potatoes get golden and tender, usually about 15 minutes. You gotta keep an eye so they don’t stick or burn.
Step 2: While potatoes work their magic, melt 2 tablespoons salted butter in a separate pan over medium heat. Add the chopped shallot and cook until softened, around 3 minutes. It’s a slow melt and build flavor kinda deal here.
Step 3: Garlic goes next. Cook your 3 minced cloves with shallots for 1 minute until you smell that lovely garlic aroma. That’s the cue the sauce is coming alive.
Step 4: Pour in 1 cup heavy cream and ½ cup chicken or fish stock. Toss in 2 fresh rosemary sprigs. Let simmer until the sauce thickens a bit, about 5 minutes. Remove rosemary before moving on.
Step 5: Add cod fillets to the skillet with potatoes. Give them a lil sprinkle of the remaining salt and pepper. Pour your creamy rosemary sauce all over the top.
Step 6: Cover the skillet. Use natural release on your pressure cooker for about 8 minutes until cod is opaque and cooked through. That tender pull means it’s time to eat. Serve warm with optional parsley on top for a fresh touch.

Easy Tweaks That Make Life Simple

If you’re short on time, swap Yukon golds for baby potatoes but slice ’em thinner so they cook fast.
Using pre-chopped garlic or shallots? You’re already winning time on your side.
Swap rosemary for thyme if that’s what’s chillin’ in your fridge, works just as good.
Dijon mustard? Sometimes I swap that for a smear of whole grain mustard to add a bit more texture.
If you wanna cut down on cleanup, try cooking potatoes and fish together from the start with a slight tweak to timing, just watch potatoes so they don’t mush up.

That First Bite Moment

You take your fork, scoop up a bit of creamy sauce-slicked potato, and right away you know you nailed it. The potato is tender but holds its shape — it’s like it soaked up all the yummy rosemary flavor.

The cod flakes apart easily and feels juicy like it didn’t just sit under heat for ages. That creamy sauce hugs every bit with its rich flavor and hint of lemon zest making it not too heavy.

A dab of those salty capers sneaks in surprise, popping between your taste buds with a bit of briny zing. And the pepper sprinkle leaves a tiny kick that warms you from inside out.

You find yourself eating slow, not wanting it to end. The whole dish sings simple comfort with a touch of elegance — you’re dang proud you made this all in your pressure cooker.

Q: Can I use other fish instead of cod?

Q: How do I know when the cod is done?
A: When it flakes easily with a fork and is opaque all the way through, you got it. No gummy spots allowed!
