Ingredients for Pressure Cooker Pot Roast Recipe Onion Soup Mix
Transform a chuck roast into fork-tender perfection with these rich, savory pantry staples and fresh vegetables.
| Ingredient | Amount | Notes |
|---|---|---|
| Chuck Roast 🥩 | 2 ½ lb | Boneless, cut into large chunks |
| Onion Soup Mix 🧅 | 1 package | 10 oz size preferred |
| Beef Broth 💧 | 1 ½ cups | Low-sodium for better control |
| Yellow Onions 🧅 | 2 whole | Large, quartered |
| Carrots 🥕 | 4 whole | Peeled, cut into 2-inch pieces |
| Yukon Gold Potatoes 🥔 | 1 ½ lb | Peeled, cut into chunks |
| Garlic Cloves 🧄 | 4 cloves | Minced for robust flavor |
| Olive Oil 🫒 | 2 tbsp | For searing the meat |
| Worcestershire Sauce 💧 | 2 tbsp | Adds umami depth |
| Dried Thyme 🌿 | 1 tsp | Crushed between fingers |

The chuck roast is non-negotiable for this method—its marbling breaks down beautifully under pressure, yielding that signature melt-in-your-mouth texture. Costco and Whole Foods carry high-quality chuck with excellent fat distribution. For the onion soup mix, Lipton is reliable, but store-brand versions work equally well. Select beef broth with low sodium to control seasoning precisely, as the soup mix already contributes significant salt.
Out of onion soup mix? Combine 1 tbsp onion powder, 1 tbsp beef bouillon, 1 tsp sugar, and 1/2 tsp paprika as a substitute. Yukon Gold potatoes can be swapped for russets (they’ll hold shape better), while parsnips make a great carrot alternative. For a deeper umami kick, add 1 tbsp soy sauce alongside the Worcestershire. Fresh rosemary can replace thyme if that’s what you have on hand.
This dish reheats exceptionally well—flavors intensify after 24 hours. Store leftovers in airtight containers for up to 4 days in the fridge or freeze for 3 months. The broth thickens as it cools, making it perfect for gravy or stew the next day.

Step-by-Step Instructions for Pressure Cooker Pot Roast with Onion Soup Mix
This method delivers fall-apart tender meat with minimal active cooking time.
Step 1: Sear the Chuck Roast
Set your pressure cooker to sauté mode and add the 2 tbsp Olive Oil. Once shimmering, pat the 2.5 lb Chuck Roast dry with paper towels and season all sides with the 1 tsp Kosher Salt and 0.5 tsp Black Pepper.
Sear the meat for 4-5 minutes per side until deeply browned. This creates a flavorful fond that will dissolve into the cooking liquid. Don’t rush this step—wait until the meat releases easily from the pot before turning.
Step 2: Deglaze and Build the Cooking Liquid
Remove the chuck roast and set aside. Add the 2 whole Yellow Onions, 4 whole Carrots, and 1.5 lb Yukon Gold Potatoes to the pot. Pour in the 2 tbsp Worcestershire Sauce and stir, scraping up all browned bits from the bottom.
Add the 1 package Onion Soup Mix, 1.5 cups Beef Broth, 4 cloves Garlic Cloves, 1 tsp Dried Thyme, and 1 whole Bay Leaf. Stir to combine, then return the chuck roast to the pot, nestling it among the vegetables.
Step 3: Pressure Cook Until Tender
Secure the lid and set the pressure cooker to high pressure for 60 minutes. The pot will take 10-15 minutes to come to pressure before the cooking time begins.
Once the timer sounds, allow the pressure to release naturally for 15 minutes, then quick-release any remaining pressure. The chuck roast should be fork-tender and the vegetables soft but not mushy.
Step 4: Rest and Adjust Seasoning
Carefully remove the lid and discard the bay leaf. Transfer the chuck roast to a cutting board and let it rest for 10 minutes to allow the juices to redistribute.
Taste the cooking liquid and adjust seasoning with additional Kosher Salt or Black Pepper if needed. Serve the pot roast sliced or shredded, with the vegetables and broth spooned over the top.
Pro Tips For Making Pressure Cooker Pot Roast Recipe Onion Soup Mix
- Sear the Chuck First: Take 5 extra minutes to brown the chuck roast in the pressure cooker before adding liquids—it locks in flavor and keeps the meat from tasting boiled. I skipped this once and the roast was noticeably flatter.
- Cut Onions Thick: Slice the yellow onions into ½-inch wedges instead of dice so they hold shape under pressure. Thin pieces turn to mush, and you’ll lose that nice texture against the tender beef.
- Deglaze Well: After searing, pour in ½ cup beef broth and scrape the browned bits off the bottom—those stuck-on fond dissolve into the sauce and add serious depth. Skipping this step wastes flavor.
- Use Half the Soup Mix: One packet of onion soup mix can be overpowering in a pressure cooker; use half and supplement with a pinch of salt if needed. My first batch tasted like a salt lick until I dialed it back.
Troubleshooting This Dish
Pressure Not Building
If your cooker isn’t reaching pressure, check the sealing ring first—it should be clean and properly seated. Ensure the release valve is set to “Sealing” not “Venting.” Also verify you have enough liquid—1.5 cups minimum for most models. 💡
Burn Notice Error
This usually means food stuck to the bottom. Quick-release pressure, open the lid, and scrape the pot with a wooden spoon. Add ½ cup extra broth and restart. To prevent, always deglaze thoroughly after searing.
Meat Not Tender
If your roast isn’t fork-tender after 60 minutes, return it to pressure for another 15-20 minutes. Older or leaner cuts may need extra time. Never exceed 90 minutes total or meat can overcook.
Sauce Too Thin
Remove the lid and set to sauté mode to reduce the liquid for 5-10 minutes. For faster results, mix 1 tbsp cornstarch with 2 tbsp water and stir in while simmering.
Vegetables Mushy
Cut potatoes and carrots into larger chunks (at least 2 inches). If they still overcook, add them after the first 30 minutes of pressure cooking using quick-release.
Overly Salty
Dilute with ½ cup water or low-sodium broth and simmer uncovered. Next time, reduce the onion soup mix to ¾ package or use low-sodium broth exclusively. 🌟

Frequently Asked Questions
Can I use a different cut of beef?
Chuck roast works best due to its marbling, but brisket or round roast are good alternatives. Avoid lean cuts like sirloin—they can turn dry under pressure.
Do I need to brown the meat first?
Yes! Searing creates a flavorful fond that deepens the sauce. Skip this, and you’ll lose rich, caramelized depth. Take the extra 4-5 minutes per side.
Can I add other vegetables?
Try mushrooms, parsnips, or celery for extra flavor. Just cut them into 2-inch chunks so they hold up during cooking.
How do I thicken the sauce?
Simmer uncovered on sauté mode for 5-10 minutes to reduce. For faster results, mix 1 tbsp cornstarch with 2 tbsp water and stir in.
