How to make the ultimate Instant Pot Guinness Beef Stew

Sear the beef. Season the stew meat with salt and pepper. Set your Instant Pot to Sauté and heat 1 tablespoon olive oil. Working in two batches, add the beef and cook for about 2 minutes per side, until well-browned. Scoop the browned beef aside—it should smell caramelized and look mahogany in spots.
Brown the mushrooms. Add another tablespoon olive oil to the pot, then toss in the mushrooms. Sauté about 4 minutes per side, letting them develop a deep color and releasing their juices. Remove the mushrooms once browned and set aside.
Sauté the aromatics. Drizzle in the last tablespoon of olive oil, add diced onion and celery, and cook for 3–5 minutes, stirring occasionally, until softened and glossy. Stir in garlic and tomato paste and sauté for another 2 minutes, until you catch the unmistakable, sweet smell of roasting garlic and see the tomato paste darken.
Deglaze with Guinness. Pour in the Guinness (or your favorite stout) to scrape up all the brown bits at the bottom—those are pure flavor! Toss the browned beef back in, along with Dijon mustard, Worcestershire sauce, sugar, bay leaves, thyme, and beef stock. Stir gently to combine and check for any stuck-on bits.
Pressure cook the beef. Secure the Instant Pot lid, set the valve to sealing, and choose the Meat/Stew function for 30 minutes. When finished, use the quick release valve to let out the steam quickly.
Add the vegetables. Open the lid and drop in potatoes and carrots, making sure they’re mostly submerged. Re-seal the lid and set to pressure cook/manual for another 4 minutes. Quick release the pressure once again.
Thicken and finish. Stir together cornstarch and a little water in a small bowl to form a slurry. Pour this into the hot stew along with the cooked mushrooms. Stir well—the sauce should thicken beautifully and become glossy as it sits. Remove the bay leaves and thyme sprigs.
Season to taste. One final taste—add more salt and pepper as needed, then ladle into deep bowls and enjoy every comforting bite.

Tips, troubleshooting, and avoiding common Instant Pot pitfalls

This Hearty Instant Pot Guinness Beef Stew can be a showstopper, but there are a few classic pitfalls to watch out for. Here’s how to guarantee stew success every time:

Tough or dry beef? Make sure to sear the beef in batches to avoid overcrowding—this helps achieve a golden-brown crust and prevents steaming. Also, use the right cut (round chuck is perfect).
Thin stew? If your stew seems runny, don’t skip the cornstarch slurry. Let it simmer a few extra minutes after adding the slurry so the sauce thickens as it should. Remember, it will get thicker as it stands.
Undercooked vegetables? Cut potatoes and carrots into even-sized, bite-sized pieces for uniform cooking. If they’re still too firm, use Sauté for a few more minutes, stirring gently.
Liquid or burnt-on bits at the bottom? Deglaze thoroughly after searing and sautéing. Scraping up the browned bits after the Guinness goes in will prevent the burn warning on the Instant Pot.
Bland flavor? Salt slowly, in layers, and taste after pressure cooking. Fresh thyme and Worcestershire sauce add an extra punch—don’t leave them out!

Trust your senses and don’t rush the browning steps—those golden edges and rich aromas are essential!

Pairings and creative spins for your Guinness Beef Stew

This stew is a meal on its own, but pairing it with the right sides or tweaking it for your mood can make it extra special. Here’s how you can bring even more excitement to your table:

Serve with rustic bread. Thick slices of country bread or a loaf of Irish soda bread are made for soaking up all that savory gravy.
Add a crisp green salad. Something simple and peppery (think arugula or watercress) balances the richness.
Try mashed potatoes. For those who can’t get enough potato, serve stew over creamy mash for a doubly comforting twist.
Creamy polenta. A fun alternative base if you want to soak up every last bit of sauce.
Make it vegetarian. Swap the beef for chunks of portobello mushroom and double the carrots for a meatless but satisfying version.
Feeling spicy? Add a pinch of chili flakes or a splash of hot sauce for a bolder, modern twist.
Lighten it up. Use less olive oil for sautéing and trim extra fat from the beef before browning.
Festive touches. Toss in parsnips, a handful of frozen peas, or even a bit of par-cooked barley for extra texture and color.

This is the stew you’ll reach for when the nights are long—or when you want a taste of the Irish countryside, no matter the season.

FAQs about Hearty Instant Pot Guinness Beef Stew

Can I make Hearty Instant Pot Guinness Beef Stew ahead of time?

Absolutely! The flavors of this stew deepen as it sits, so making it a day ahead can be even better. Once cooled, store it in an airtight container in the fridge. Reheat gently in the Instant Pot (Sauté mode) or on the stove until hot and bubbling.

What are some good substitutes if I don’t have Guinness for this beef stew?
