This Instant Pot Guinness Pot Roast is an easy way to make tender, flavorful beef without spending all day in the kitchen. Chuck roast cooks under pressure with onions, beef broth, Worcestershire sauce, and Guinness stout for a rich, savory cooking liquid.
Once the beef is tender enough to shred with two forks, return it to the juices so it can soak up even more flavor. Serve it as a hearty main dish or thicken the cooking liquid into a delicious gravy to spoon over the beef and your favorite sides.

- Sear the roast. Set the Instant Pot to Sauté mode on high. Once hot, add the roast and sear for 4–5 minutes per side until a deep golden-brown crust forms. Transfer the beef to a plate.

- Deglaze the pot. Turn off Sauté. Pour in the beef broth and Guinness, then use a wooden spoon to scrape all the browned bits from the bottom of the pot. This step helps prevent the Instant Pot’s Burn warning. Stir in the Worcestershire sauce.1 Cup Beef Broth, 2 Tablespoons Worcestershire Sauce, 1 Cup Guinness Stout Beer
- Add the beef. Return the seared roast to the pot, nestling it into the cooking liquid and onions.
- Pressure cook. Secure the lid and set the valve to Sealing. Select Pressure Cook or Manual on High Pressure for 60 minutes.
- Release the pressure. When cooking is complete, allow a natural pressure release for 20 minutes. Carefully release any remaining pressure by turning the valve to vent before opening the lid. (following your Instant Pot’s instructions).
- Shred the beef. Transfer the roast to a cutting board. Remove any large pieces of fat, then shred the beef using two forks.
- Place the shredded beef back into the cooking liquid and stir to coat. Let it sit for a few minutes to absorb the flavors before serving.
Your Own Private Notes
Notes
Optional Guinness Gravy
You can turn the remaining cooking liquid into a thicker gravy.- Remove the shredded beef from the Instant Pot and set it aside.
- Select Sauté and bring the cooking liquid to a gentle simmer.
- In a small bowl, whisk together 2 tablespoons cornstarch and 2 tablespoons cold water until smooth.
- Slowly whisk the slurry into the simmering liquid.
- Cook for 2–3 minutes, stirring frequently, until the gravy thickens. If it becomes too thick, add a little beef broth.
- Return the shredded beef to the gravy or spoon the gravy over the beef when serving.
Tips for the Best Results
- Choose chuck roast. This cut has enough connective tissue and marbling to become tender during pressure cooking.
- Sear for Flavor. Browning the meat develops flavor that carries through the entire dish.
- Scrape the bottom well. Make sure all the browned bits are loosened before pressure cooking to help avoid a Burn warning.
- Allow time for natural release. The 20-minute natural release helps the cooking process finish gradually.
- Check for tenderness. The beef should pull apart easily with two forks. If it is still tough, pressure cook it for another 10–15 minutes, followed by another natural release.
Nutrition
Can You Double This Recipe?
Yes. For a larger 3½–4-pound chuck roast, you can keep the listed liquid measurements if they meet your particular Instant Pot model’s minimum liquid requirement. Increase the pressure-cooking time to approximately 80 minutes, followed by a 20-minute natural release.
The larger roast will also release additional juices as it cooks. Always follow your pressure cooker’s capacity limits and manufacturer instructions.
What to Serve with Guinness Pot Roast
This shredded beef pairs well with mashed potatoes, roasted carrots, buttered egg noodles, or crusty bread for soaking up the savory juices. Steamed green beans or roasted Brussels sprouts add a fresh vegetable side.
Added Vegetables
If you cook carrots and potatoes directly in the Instant Pot with the beef, expect them to be very tender after the full cooking time. For firmer vegetables, prepare them separately and serve alongside the roast.
How to Store Leftovers
Refrigerator: Store the cooled beef with some of its cooking liquid in an airtight container for 3–4 days.
Freezer: Freeze the shredded beef in meal-sized portions with enough cooking liquid to keep it moist. Use freezer-safe containers or bags and freeze for up to 3 months for best quality.
Reheating: Warm the beef with its juices in a covered saucepan over medium-low heat or in the microwave in short intervals, stirring as needed. Add a splash of beef broth if necessary.
Thaw frozen portions in the refrigerator before reheating when possible.
Does Guinness make the beef taste like beer?
Guinness adds a deep, roasted, slightly malty flavor to the cooking liquid. Combined with the beef, onions, herbs, and Worcestershire sauce, it creates a savory sauce rather than an overwhelmingly beer-flavored dish.
Can I use a different beer?
Yes. Another stout or dark beer can work well. A different beer may change the flavor, so choose one whose roasted or malty notes you enjoy. You can also replace the beer with additional beef broth for a version without alcohol.
Can I make this recipe without shredding the beef?
Yes. You can serve the roast in large chunks if you prefer. For chuck roast, the goal is tenderness, so allow additional cooking time if the meat doesn’t separate easily with a fork.
Can I make gravy without cornstarch?
Yes. You can use a flour-and-water slurry instead, whisking thoroughly to prevent lumps. Alternatively, simmer the cooking liquid uncovered until it reduces to your preferred consistency.
A Hearty Meal Made Easy
This Instant Pot Guinness Pot Roast makes a satisfying dinner with relatively little hands-on work. The tender shredded beef and rich cooking juices are delicious served simply or finished with homemade gravy. Save any leftovers for another easy meal during the week.
