Your Complete Cooking Timeline
Heat the olive oil in a large skillet over medium heat. You gotta get it hot enough so sausages get that nice browned crust.
Add the sausages and cook 'em all around not just one side, usually about 10 minutes does the trick. When browned, pull them off and set aside.
Use the same skillet for onions, adding all those sliced beauties. Cook slowly, stirring now and then, got about 10 minutes till they're soft and caramelized.
Sprinkle the flour on top of onions and stir 'round so it's all coated. Cook it another minute or two, making sure that raw flour taste is gone before pouring any liquid.
Pour in the white wine, and use a wooden spoon to scrape up all those great browned bits stuck below. That9s where flavor lives.
Next comes the beef stock, garlic powder, balsamic vinegar, and Dijon mustard. Stir it all together till it looks kinda saucy and pretty thick.
Return the sausages to the skillet, cover it tight, and transfer everything to your pressure cooker. Lock on the lid with the sealing ring and let the pressure build. Cook for about 10 to 15 minutes, then do a natural release so juices settle and flavors meld nice.
Time Savers That Actually Work
First, slice onions in advance and keep 'em in the fridge. You9ll thank yourself when it9s go time.
Instead of making mash from scratch, grab some good-quality instant mash or leftover mashed potatoes. It works real good and saves lots of hassle.
Use pre-cooked sausages if you're short on time. They just need reheating and soaking in that yummy gravy.
Consider using your pressure cooker9s saut E9 function for browning and caramelizing all in one pot. It cuts down dishes and keeps heat steady.
That First Bite Moment
When you finally scoop up a sausage with a load of that thick onion gravy, you get a cozy warmth that just hits the spot. Juices burst with every bite thanks to the pressure cooker9s tender pull.
The creamy mash is the perfect partner, soaking up all that sauce, with buttery sweetness that melts in your mouth. You sense every flavor in harmony.
Onion pieces are soft, sweet, and just a little tangy from the vinegar and mustard mix, rounding out each mouthful real nicely.
Peas on the side add a fresh crispness that balances y9all9s meal perfectly, making every forkful a little celebration.

Keeping Leftovers Fresh and Ready
First tip is to cool leftovers quickly and store in airtight containers inside the fridge. That keeps sauces and mash tasting spot on for next day.
If you wanna freeze it, separate sausages and mash in different containers. Wrap well so no freezer burn sneaks in.
When reheating, thaw overnight in fridge then warm slow over low heat or in the pressure cooker using slow release to keep it tender.
Fresh peas are best eaten right away but if leftovers remain, toss 9em in the fridge sealed tight in a small container so they stay crisp a day or two.
What People Always Ask Me
- Can I use chicken sausages instead? Totally yes, they just cook a bit faster, so keep an eye on cooking time so they don9t dry out.
- Do I really need the white wine? It adds nice flavor but you can swap with extra beef stock or a splash of apple cider vinegar if you want.
- What9s the deal with the sealing ring? It helps keep pressure sealed inside, so your sausages cook right and gravy thickens nicely. Check yours is clean and in good shape before starting.
- Can I add other veggies to this? Sure y9all! Carrots and peas go well. Add them after the initial pressure cook part and do a quick saut E9 or steam in the pot.
- How do I know when to do natural release vs quick release? For this, natural release is best since it lets meat rest and juices redistribute without drying out.
- Is it okay to brown sausages in the pressure cooker? Yep, using the saut E9 mode makes it easier to keep everything in one pot. Just brown first then add other ingredients.
