Steam curls up from the valve and your stomach starts talking back.

You sense that warm, comforting feeling creeping in, the kind you don’t get everyday. It’s like your kitchen’s whispering a little secret that something delicious is on its way.
The broth depth in your pressure cooker is just right, that hint of moisture mixing with the steam cues you’re watching like a hawk. That valve hiss is music to your ears, telling you the focaccia is getting just the right love it needs to rise up perfectly.
Why This Recipe Works Every Single Time
- The sourdough discard brings that tangy depth, making your focaccia taste old school but fresh.
- Combining instant yeast with sourdough speeds up rising but keeps that great flavor.
- You get caramelized onions that add a sweet and savory punch, no extra fuss.
- Olive oil drizzle keeps the crust crispy and golden, just how you want it.
- The pressure cooker’s steam keeps the inside moist while the top crisps up in the oven.
- Finger dimpling the dough brings that classic focaccia look and texture you crave.
- Slow release after pressure cooking helps your bread settle without getting soggy.
Everything You Need Lined Up
- 1 cup sourdough discard
- 2 cups all-purpose flour
- ¾ cup warm water
- 1 teaspoon salt
- 1 teaspoon sugar
- 1 teaspoon instant yeast
- 3 tablespoons olive oil, divided
- 1 large onion, thinly sliced
- Pressure cooker with a sturdy valve system
- Greased baking pan
Make sure your ingredients are ready before you start. The warm water helps wake up the yeast so your dough gets going right away. The sourdough discard brings that lovely tang which kinda sets this focaccia apart.
Don't forget about your tools - you’ll need a good baking pan to shape the focaccia and a pressure cooker with a reliable float valve so you can read those steam cues perfectly.
Slice the onion thin enough so they caramelize real good and get that sweet flavor without burning. Olive oil is split up to keep things crispy and add richness, so remember to save some for drizzling later.

The Full Pressure Cooker Journey
Step 1: In a large bowl, you combine your sourdough discard, flour, warm water, salt, sugar, and instant yeast. Mix it up until you get a sticky dough that’s kinda lumpy but coming together.
Step 2: Cover it up and let the dough rest at room temp for about 2 hours. This resting lets the yeast and sourdough work their way to double the dough size. You’ll notice the float valve's quiet, but you’re watching the steam cues in your mind.
Step 3: While dough rests, heat 1 tablespoon of olive oil in a skillet. Toss in the thin onion slices and cook over medium heat till they’re caramelized and sweet, about 15 to 20 minutes. Keep an eye on ‘em—they’re gonna smell dang good.
Step 4: Preheat your oven to 425 degrees Fahrenheit. Grease your baking pan with 1 tablespoon olive oil and press the rested dough evenly into it. Use your fingers to dimple the surface, that classic touch everyone loves.
Step 5: Drizzle the last olive oil on top and spread those caramelized onions like a tasty blanket. Slide the pan into the oven and bake for 25 to 30 minutes till the crust is golden and cooked through.
Step 6: Let the focaccia cool a bit before slicing into it. You smell that broth depth from being in the pressure cooker, with steam cues still lingering in the kitchen air. When it cools, you’re ready to enjoy that perfect bite.
Easy Tweaks That Make Life Simple
- You can skip the instant yeast if you want to keep it super sourdough only, just remember to add extra resting time.
- Use pre-sliced or frozen caramelized onions if you’re short on time. It works real good and still tastes fancy.
- Swap the baking pan for a cast iron skillet if that's what you got—just press the dough in and follow the same steps.
These shortcuts don’t change the core feeling of this recipe but save your energy when life is running fast. Sometimes you gotta be easy on yourself, and these tweaks help make that happen.
That First Bite Moment
You pick up a fresh slice, feeling the crust’s sturdy but not tough. Pressing your finger, you notice how the dimples stretch and the olive oil shines in little pools.
The smell hits you first, that caramelized onion sweetness mingling with the sourdough tang. It’s like all the senses know this is gonna be good before your teeth even sink in.
Then comes the warm hug of bread, soft and airy but with a slight chew. The crust crackles a little when you bite down and the flavors just melt together, making you wanna go for another slice fast.

Your Leftover Strategy Guide
Wrap your focaccia tight in plastic wrap and keep it at room temp if you’re eating it in a day or two. It stays soft and tasty this way.
If it’s gonna hang around longer, toss it in an airtight container in the fridge. Just warm it up in the oven later to get that fresh crust feeling back.
The freezer is your friend for longer storage. Slice first, wrap each piece tightly, and thaw on the counter before reheating.
Reheating is best in the oven or toaster oven so you get that olive oil crisp and steam escapes. Avoid microwaves if you want to keep the crust from turning chewy.
What People Always Ask Me
- Can I use only sourdough without yeast? Yep, but expect the dough to rest longer, like 4 to 6 hours, since the yeast won’t speed things up.
- Why press dimples in the dough? Those dimples stop bubbles from rising too fast and hold olive oil and toppings, giving focaccia its classic look and flavor.
- Can I caramelize onions in the pressure cooker? You could, but I like the skillet better for control. Onions need slow cooking and watching closely so they don’t burn.
- What’s broth depth mean in this recipe? It’s about moisture level created in pressure cooker that keeps bread moist without sogginess.
- How do I know when dough has doubled? It’s kinda like when you poke it and the dent fills back up slow. You see the dough puff out and get full of air bubbles.
- Why’s slow release important? Slow release helps the bread settle gently, so it doesn’t collapse or get doughy inside.
