Instant Pot French Onion Pot Roast Recipe

There’s something about the rich, savory flavor of French onion soup combined with the hearty tenderness of pot roast that makes this dish unforgettable. This Instant Pot French Onion Pot Roast takes everything you love about a classic French onion soup—the caramelized onions, the beefy broth, the depth of flavor—and infuses it into tender chunks of beef chuck. And thanks to the Instant Pot, what would normally take hours on the stove is ready in a fraction of the time. It’s cozy, comforting, and ridiculously easy to make, which is exactly what you need on a chilly evening.

A bit of backstory: How French onion flavors meet pot roast

French onion soup is a timeless classic, originally a poor man’s dish in France that made use of simple ingredients like onions, beef stock, and bread. The combination of caramelized onions and beef broth brings an umami depth that feels almost indulgent, yet it’s humble at heart. Pot roast, on the other hand, is a mainstay of American home cooking—tender, flavorful beef often slow-cooked with onions and spices. Merging these two dishes feels natural, creating a flavor-packed, ultra-tender pot roast that has all the depth and warmth of French onion soup, but with a hearty twist. And with the Instant Pot, you can have it on the table in just over an hour.

My first time making this dish

The first time I made this Instant Pot French Onion Pot Roast, I was a little skeptical. French onion soup has such a unique, deep flavor profile that I wasn’t sure it would translate to a pot roast. But as soon as I lifted the lid after the natural release, I was hit with the most incredible aroma—the kind that makes you feel like you’re sitting by a fireplace on a cold night. The beef was fall-apart tender, and the onions had melted down into the broth, creating this luscious, savory gravy. I remember my family practically running to the kitchen, and by the end of the meal, every plate was clean. That’s when I knew I had to share this recipe!

Let’s talk ingredients: flavor powerhouses

• Beef Chuck Roast: This cut of beef is perfect for slow-cooking (or pressure cooking!) because it becomes tender and juicy as it cooks. If you can’t find chuck roast, you could try a beef shoulder roast or brisket, but chuck roast really holds up well and shreds beautifully.
• Steak Seasoning: This adds layers of flavor, with a mix of salt, pepper, garlic, and other spices. If you don’t have steak seasoning on hand, just go with a blend of salt, black pepper, garlic powder, and a pinch of paprika.
• Onions: White or yellow onions work best here. They caramelize slightly in the Instant Pot, creating a naturally sweet, mellow flavor that pairs perfectly with the beef. If you’re a fan of a slightly sweeter dish, you could even try using Vidalia onions.
• Beef Broth: This is the base of our “gravy,” so use a good-quality broth if you can. I like to use reduced-sodium beef broth so I can control the saltiness. You can also use vegetable broth if you’re out of beef broth.
• Better Than Beef Bouillon: This is like a secret weapon for adding that extra “beefy” depth. If you don’t have it, you can skip it, but I highly recommend it for a more robust flavor.
• Garlic and Bay Leaf: Garlic adds a hint of sharpness, while the bay leaf provides a subtle, earthy note. Don’t forget to remove the bay leaf before serving!
• Cornstarch: This is our thickener for the gravy. You can also use flour if you’re out of cornstarch—just make sure to whisk it well to avoid lumps.

Essential kitchen tools for this recipe

• Instant Pot: The star of the show here! The Instant Pot makes it easy to cook this pot roast in just over an hour, infusing the meat with tons of flavor. If you don’t have an Instant Pot, a slow cooker will work, but you’ll need to adjust the cooking time to about 6-8 hours on low.
• Tongs: You’ll want these to easily handle the chunks of beef. Trust me, using tongs makes transferring the meat in and out of the Instant Pot a breeze.
• Whisk: Essential for mixing the cornstarch slurry into the gravy. A whisk helps to break up any lumps and creates a smooth, silky sauce.
• Ladle: For serving that delicious gravy over the shredded beef. A ladle makes it easy to drizzle just the right amount over each serving.

Step-by-step: making Instant Pot French onion pot roast

1. Season the beef: Start by cutting the chuck roast into 10 pieces. This might seem like a lot, but it helps the meat cook evenly and absorb more flavor. Place the pieces in the Instant Pot, then sprinkle with steak seasoning and kosher salt.
2. Add the liquid and aromatics: Pour in 1 and ¼ cups of beef broth, then add the minced garlic over the meat. The garlic will infuse as the beef cooks, creating a rich, savory flavor.
3. Layer the onions: Place the sliced onions on top of the garlic and beef. Don’t stir—you want the onions to steam and release their juices as the pot roast cooks, which helps create that luscious gravy.
4. Flavor boost with bouillon and bay leaf: Add the Better Than Beef Bouillon and drop in the bay leaf. These little additions give the broth an extra kick of flavor.
5. Pressure cook: Close and lock the lid, and make sure the valve is set to “sealing.” Set the Instant Pot to manual high pressure for 60 minutes. Now you can sit back and relax!
6. Natural release: When the cooking time is up, let the pressure release naturally for 25 minutes. This slow release helps keep the meat tender and juicy. When the time is up, carefully remove the lid.
7. Shred the meat: Take out the beef chunks and shred them with two forks. They should be falling apart at this point—perfectly tender.
8. Make the gravy: Remove the bay leaf, then mix together the remaining ¼ cup of beef broth with 2 tablespoons of cornstarch. Press the “sauté” function, stir in the cornstarch mixture, and cook until thickened, about 2 minutes. This is your gravy, rich and savory, ready to spoon over the shredded beef.

Make it your own: Variations and adaptations

• Low-Carb Option: If you’re watching carbs, omit the cornstarch slurry or replace it with a keto-friendly thickener like xanthan gum. The flavors will still shine!
• Gluten-Free Option: Good news—this recipe is naturally gluten-free! Just double-check that your beef broth and bouillon are certified gluten-free.
• Vegetable Boost: Add some carrots and celery on top of the onions for a more veggie-forward dish. These will cook down and add extra flavor to the broth.
• Spicy Kick: If you like a bit of heat, sprinkle in some red pepper flakes with the seasoning. The spice pairs nicely with the rich broth and savory onions.
• Herb Swap: Instead of a bay leaf, you could add a sprig of fresh rosemary or thyme for a slightly different aromatic profile.

How to serve and garnish

For a cozy, family-style presentation, serve the shredded beef on a large platter with the gravy poured over the top. Garnish with a sprinkle of fresh parsley for a pop of color and a hint of freshness. Pair it with mashed potatoes or buttered noodles to soak up the gravy. A side of roasted green beans or a fresh green salad will round out the meal beautifully.

beverage pairings

• Iced Tea with Lemon: The slight acidity and refreshing quality of iced tea balance out the rich flavors of the pot roast perfectly.
• Sparkling Water with a Twist: A sparkling water with a splash of lime or lemon is a light and crisp choice that won’t compete with the dish’s robust flavors.
• Apple Cider: If it’s fall, a glass of warm apple cider complements the warmth of the dish wonderfully, adding a touch of sweetness.

Storage and reheating tips

Leftovers store beautifully! Place the meat and gravy in an airtight container and refrigerate for up to 3 days. When you’re ready to reheat, you can use the microwave, but I prefer warming it gently on the stovetop over low heat. Just add a splash of beef broth to loosen up the gravy if it’s thickened too much in the fridge.

If you’d like to freeze it, store the meat and gravy separately in freezer-safe containers for up to 3 months. Thaw in the fridge overnight before reheating.

Adjusting for different serving sizes

If you’re cooking for a smaller crowd, you can easily halve the recipe. Keep the cooking time the same, as the Instant Pot will adjust for the smaller volume. For a larger crowd, you can double the recipe as long as your Instant Pot can handle the volume. Just make sure not to fill it past the maximum line!

Frequently asked questions

1. Can I use a different cut of beef?
