Gathering these simple ingredients is the first step to creating a truly magical French onion soup pot roast. You’ll need a good cut of beef, plenty of onions, and a few pantry staples to achieve that classic French onion flavor. Here’s what you’ll need:

3 to 4 lb chuck roast – the star of our dish, ensuring tender results
2 tbsp olive oil – for searing the roast and sautéing the onions
2 large yellow onions, thinly sliced – crucial for that deep, sweet onion flavor
1 tbsp butter – adds richness to the onions as they caramelize
3 cloves garlic, minced – for an aromatic base
1 tbsp Worcestershire sauce – adds a layer of savory depth
1 tsp dried thyme – a classic herb pairing for beef
1 tsp salt – to enhance all the flavors
½ tsp ground black pepper – for a touch of spice

Fresh parsley for garnish (optional) – for a pop of color and freshness

How to Make Instant Pot French Onion Pot Roast

Let’s dive into creating this incredible French onion pot roast recipe. It’s surprisingly straightforward, even with the Instant Pot doing most of the work. You’ll be amazed at how simple it is to achieve that deep, savory flavor.

Step 1: Set your Instant Pot to “Sauté” mode. Once hot, add the 2 tbsp olive oil. Carefully place the 3 to 4 lb chuck roast into the pot and sear it for about 3–4 minutes per side, until a beautiful golden-brown crust forms. This searing is key for that rich flavor. Remove the roast and set it aside for a moment.
Step 2: Add the 1 tbsp butter to the hot pot. Toss in the 2 large yellow onions, thinly sliced. Cook them, stirring frequently, for about 8–10 minutes until they soften and turn a lovely golden color. You’ll love the sweet aroma filling your kitchen! Add the 3 cloves garlic, minced, and cook for another 30 seconds until fragrant – be careful not to burn it.
Step 3: Now it’s time to deglaze! Pour in the 1 tbsp Worcestershire sauce and the 1½ cups beef broth. Use a wooden spoon to scrape up all those delicious browned bits stuck to the bottom of the pot – this is where so much flavor comes from. Stir in the 1 tsp dried thyme, 1 tsp salt, and ½ tsp ground black pepper.
Step 4: Return the seared roast to the pot, nestling it down into the softened onions and liquid. Secure the lid, ensuring the valve is set to “Sealing.” Cook on High Pressure for 60 minutes. After the cooking time is up, let the pressure release naturally for 15 minutes before carefully releasing any remaining pressure. This natural release makes the meat extra tender.
Step 5: Carefully remove the roast from the pot. Using two forks, shred the beef into bite-sized pieces. If you prefer a thicker sauce, you can set the Instant Pot back to “Sauté” mode. Whisk together the 1 tbsp cornstarch and 1 tbsp water to make a slurry, then stir it into the pot. Simmer for 2–3 minutes, stirring constantly, until the sauce thickens beautifully.
Step 6: Spoon the rich, savory onion gravy over the shredded beef. If you like, garnish with a sprinkle of fresh parsley for a touch of color and freshness. This method truly shows you how to make French onion pot roast that rivals any slow cooker version, delivering amazing results in less time.

Pro Tips for the Best French Onion Pot Roast

Want to elevate your pot roast game? I’ve picked up a few tricks over the years that make this dish truly shine.

For the deepest flavor, don’t rush caramelizing those onions. Slow and steady wins the race for that classic French onion taste.
Always scrape up the fond (those browned bits) from the bottom of the pot after searing the roast. That’s pure flavor gold!
Make sure your chuck roast is well-marbled; fat equals flavor and tenderness, which is key for this dish.
If you have time, letting the shredded beef rest in the gravy for a few minutes before serving allows the flavors to meld even more.

How to Store and Reheat French Onion Pot Roast

This French onion pot roast is a fantastic make-ahead meal, perfect for busy schedules. Once it’s cooled down, I like to store any leftovers in an airtight container in the refrigerator.

When you’re ready to enjoy it again, reheating is simple. You can gently warm it in a saucepan over low heat, stirring occasionally, or reheat it in the microwave. If the sauce has thickened too much, a splash of beef broth or water can help loosen it up. Both methods revive that delicious flavor beautifully.

Frequently Asked Questions About French Onion Pot Roast

What is French Onion Pot Roast?

French onion pot roast is a hearty, slow-cooked dish that takes inspiration from classic French onion soup. It features a tender cut of beef, usually chuck roast, braised in a rich, savory broth infused with deeply caramelized onions, herbs like thyme, and often a splash of Worcestershire sauce. The result is incredibly tender beef with a deep, complex onion flavor that’s pure comfort food.

Why is French onion pot roast popular?

Can I use a different cut of beef for this recipe?

While chuck roast is ideal due to its marbling, which keeps it tender and moist during slow cooking, you can use other cuts like brisket or bottom round. However, these cuts might require slightly different cooking times to achieve the same tenderness, and they may not yield quite as much flavor from rendered fat.

How do I get the onions really caramelized for the best flavor?

To achieve the best caramelization, slice your onions thinly and evenly. Cook them in butter and a little oil over medium-low heat, stirring occasionally, for at least 20-30 minutes, or even longer if you have the time. Don’t rush this step; patience here builds the deep, sweet flavor that defines this dish.

Variations of French Onion Pot Roast You Can Try

While this Instant Pot French onion pot roast is fantastic as is, I love experimenting with different twists! If you’re looking to switch things up, consider these delicious variations. For a heartier meal, try adding chunks of carrots, potatoes, and celery along with the onions during the sauté step, turning it into a complete savory onion pot roast and vegetable stew. If you enjoy hearty vegetable dishes, you might like this gourds and squashes recipe.

Another popular option is to adapt this for a traditional slow cooker. Simply sear the roast and sauté the onions and garlic as directed, then transfer everything to your slow cooker and cook on low for 6-8 hours or high for 3-4 hours. For a richer flavor profile, you could add a splash of red wine along with the beef broth, or even stir in a tablespoon of Dijon mustard for a tangy kick. These simple changes can transform your French onion beef roast into something new and exciting!
