Substitutions & Swaps

Don’t have all the ingredients on hand? No problem! For the chuck roast, you could use a shoulder roast or brisket. Vegetable broth can replace beef broth if needed. If you’re missing fresh garlic, ½ teaspoon of garlic powder can substitute. Experiment with different herbs; Italian seasoning works well, or a blend of your favorites. Sweet potatoes are a delicious stand-in for regular potatoes.

Equipment Guide

The star of the show is, of course, an instant pot (6-quart or larger recommended). You’ll also need measuring spoons and cups, a cutting board, a sharp knife, and tongs for searing the roast. A trivet is essential for keeping the roast elevated above the liquid. A vegetable peeler also helps!

Step-by-Step Walkthrough

Step 1: Sear the Roast: Season the chuck roast generously with salt and pepper. Turn on the instant pot to the sauté function. Add olive oil. Once hot, sear the roast on all sides until browned. Remove the roast and set aside.

Step 2: Sauté Aromatics: Add the onion, carrots, and celery to the instant pot. Sauté until softened, about 5 minutes. Add minced garlic and tomato paste; cook for 1 minute more.

Step 3: Deglaze and Combine: Pour in the beef broth and Worcestershire sauce. Use a wooden spoon to scrape up any browned bits from the bottom of the pot. Add dried thyme, rosemary, and bay leaf.

Step 4: Pressure Cook: Place the trivet in the instant pot. Return the seared roast to the pot, placing it on top of the trivet. Secure the lid and set the valve to sealing. Cook on high pressure for 60-75 minutes (depending on the size of the roast). Allow a natural pressure release for 15 minutes, then quick release any remaining pressure.

Step 5: Add Potatoes: Carefully remove the roast and set aside. Add potatoes to the instant pot. Cook on high pressure for 5 minutes, followed by a quick pressure release.

Step 6: Shred and Serve: Remove the potatoes. Shred the roast with two forks. Return the shredded roast and potatoes to the instant pot with the cooking liquid. Serve immediately. Garnish with fresh parsley, if desired.

Expert Tips & Troubleshooting

Tip 1: Don’t Overcrowd the Pot: Make sure the roast fits comfortably in the instant pot without being overly crowded.

Tip 2: Browning is Key: Searing the roast is crucial for developing rich flavor. Don’t skip this step!

Tip 3: Adjust Cooking Time: Cooking time may vary slightly depending on the size and thickness of the roast.

Tip 4: Avoid a Tough Roast: If the roast is tough, it likely needs to cook longer. Next time, increase the cooking time by 10-15 minutes.

Flavor Variations

For a spicy kick, add a pinch of red pepper flakes or a chopped jalapeño. Incorporate mushrooms for an earthy flavor. Guinness or another dark beer can be used in place of some of the beef broth for a richer, more complex taste. A splash of balsamic vinegar at the end can brighten the dish.

Storage & Reheating

Store leftover pot roast in an airtight container in the refrigerator for up to 3-4 days. To reheat, use the microwave or stove top. For stove top reheating, add a little beef broth to prevent drying out. You can also reheat in the instant pot using the sauté function.

FAQ Section

Q: Can I use frozen roast?

A: While possible, searing a frozen roast is difficult. Increase the cooking time significantly (add at least 30 minutes) to ensure it cooks through.

Q: Can I add other vegetables?

A: Absolutely! Parsnips, turnips, or other root vegetables can be added along with the carrots and celery.

Q: Can I make gravy?

A: Yes! After removing the roast and vegetables, use an immersion blender to blend the cooking liquid. Alternatively, make a slurry with cornstarch and water and whisk it into the liquid while simmering on the sauté function.

Q: Can I use a slow cooker instead?

A: Yes, you can adapt this recipe for a slow cooker. Sear the roast first, then combine all ingredients in the slow cooker. Cook on low for 8-10 hours or on high for 4-5 hours.
