Instant Pot Pot Roast Recipe Onion Soup: Set-It-and-Forget-It Savory Comfort

This recipe transforms tough cuts of beef into fall-apart tender pot roast with minimal effort. The Instant Pot works its magic in a fraction of the time it takes in the oven, infusing every bite with rich, savory flavor from the onion soup.

What makes this dish special is how the pressure cooker locks in moisture while breaking down the meat fibers. The onion soup mix creates a deeply flavorful base that pairs perfectly with the beef and vegetables.

You’ll end up with a hearty, comforting meal that tastes like it simmered all day. The carrots and potatoes soak up the savory broth, making every component of this dish irresistibly tender.

Serve this with crusty bread to soak up every last drop of the flavorful juices. Here’s how to make it.

The beef chuck roast is non-negotiable here—look for good marbling at Costco or your local butcher. Pre-cut chuck roast works, but a whole piece lets you control the size (aim for 3-4 inch chunks). The onion soup mix? Lipton is the gold standard, but any dry mix with visible onion flakes and herbs works. Yukon Gold potatoes hold their shape better than Russets in the pressure cooker.

No chuck roast? Brisket or short ribs work but may need extra time. Swap beef broth for mushroom broth if avoiding meat. Fresh herbs can replace dried at triple the amount. For a richer sauce, deglaze the pot with red wine after searing. The tomato paste can be omitted, but it adds a subtle sweetness that balances the savory broth.

This keeps beautifully—tastes even better the next day once flavors meld. Store in the fridge for up to 4 days or freeze for 3 months. Portion leftovers into containers for easy lunches. The broth thickens as it cools, perfect for soaking crusty bread.

Step-by-Step Instructions for Instant Pot Pot Roast with Onion Soup

This hands-off method delivers tender beef and vegetables with rich, savory depth every time.

Step 1: Sear the Beef Chuck Roast

Set your Instant Pot to the “Sauté” function on normal heat. Add the 1 tbsp Olive Oil and let it heat until shimmering. Pat the 3 lb Beef Chuck Roast dry with paper towels, then season both sides with 1 tsp Kosher Salt and 0.5 tsp Black Pepper.

Sear the roast for 4-5 minutes per side until deeply browned on all surfaces. This creates a flavorful fond at the bottom of the pot that enhances the final dish. Don’t rush this step—proper browning adds complexity to the sauce.

Step 2: Build the Flavor Base

Remove the beef and set it aside. To the Instant Pot, add the roughly chopped 1 whole Yellow Onion, 4 whole Carrots (peeled and cut into chunks), and 1.5 lb Yukon Gold Potatoes (peeled and cubed). Stir in the 4 cloves Garlic Cloves, 2 tbsp Tomato Paste, 1 tbsp Worcestershire Sauce, 1 package Onion Soup Mix, 1 tsp Dried Thyme, 1 tsp Dried Rosemary, and 2 pieces Bay Leaves.

Pour in the 2 cups Beef Broth and use a wooden spoon to scrape up any browned bits from the bottom. This deglazing step ensures nothing burns during pressure cooking and incorporates all those caramelized flavors into the sauce.

Step 3: Pressure Cook to Perfection

Return the seared beef to the Instant Pot, nestling it into the vegetables and liquid. Secure the lid, set the valve to “Sealing,” and cook on high pressure for 60 minutes.

The pot will take 10-15 minutes to come to pressure before the cooking time begins. Once done, let the pressure release naturally for 15 minutes, then quick-release any remaining pressure. This natural release prevents the meat from toughening.

Step 4: Rest and Serve

Remove the beef from the Instant Pot and place it on a cutting board. Let it rest for 5-10 minutes before slicing against the grain. This resting period allows the juices to redistribute, ensuring moist, tender meat.

Meanwhile, use a fork to mash some of the potatoes slightly in the sauce, which helps thicken it naturally. Taste and adjust seasoning with additional Kosher Salt or Black Pepper if needed. Serve the sliced beef with the vegetables and sauce spooned over the top.

Regional Styles of This Dish

Southern Comfort Style

In the South, we love adding a touch of sweetness to balance the savory. I stir in ¼ cup brown sugar with the onion soup mix for a caramelized depth. Some cooks also add 1 tbsp apple cider vinegar for brightness, which cuts through the richness beautifully. 💫

Midwestern Hearty

Midwestern versions often include extra vegetables for a one-pot meal. Try adding 2 cups chopped celery and 1 cup frozen peas during the last 5 minutes of cooking. This makes it a complete, hearty meal that’s perfect for cold winter nights.

Texas Bold

Texas pitmasters love adding smoky elements. I mix in 1 tsp smoked paprika and ½ tsp chipotle powder with the dry rub. For extra depth, some add 1 chopped jalapeño with the onions. The heat pairs perfectly with the savory onion soup base. 🔥

New England Classic

This region favors a simpler approach with root vegetables. I use parsnips and rutabagas in place of carrots and potatoes. The slightly sweet, earthy flavors complement the beef beautifully. A splash of 1 tbsp soy sauce adds umami richness.

Pacific Northwest

Here, we incorporate local produce like mushrooms and kale. Sauté 8 oz cremini mushrooms with the onions, and stir in 2 cups chopped kale after pressure cooking. The earthy mushrooms and hearty greens add a fresh, robust touch.
