Instant Pot French Onion Pot Roast Recipe

French onion pot roast – even the name sounds comforting, right? This recipe takes everything you love about a classic French onion soup and combines it with the rich, tender texture of a slow-cooked pot roast. And here’s the kicker: it’s all done in the Instant Pot, which means you can have this hearty, fall-apart-tender roast on your table in just over an hour. Perfect for those chilly days when you’re craving something warm and satisfying but don’t have all day to spend in the kitchen.

I’ll be honest – I was skeptical the first time I made this. I’ve always associated pot roast with long, slow hours in the oven or a crockpot, with the whole house smelling incredible for half the day. But the Instant Pot really surprised me. Somehow, it manages to lock in all that flavor and tenderness in a fraction of the time. This version has quickly become a family favorite, especially on busy weeknights when we need a hearty meal but are short on time.

A personal pot roast memory

Growing up, pot roast was a Sunday dinner staple in my family. I remember the smell filling up our house, making me impatient for dinnertime. My mom would always start the roast early in the afternoon, and by the time we sat down, the meat was so tender it practically melted on the fork. This Instant Pot recipe brings back those cozy memories but with a modern twist that fits perfectly into my busy schedule. And because it’s inspired by French onion soup, it has an extra layer of flavor from the caramelized onions and rich broth that makes it feel just a bit fancier – perfect for impressing guests or just treating yourself.

The origins of French onion pot roast

Traditional French onion soup dates back to 18th-century France, where it was originally considered a “poor man’s dish” made with onions and stale bread. Over time, it evolved into the rich, cheesy delight we know and love today. This recipe takes inspiration from the flavors of French onion soup – the deep, savory sweetness of caramelized onions, the richness of beef broth – and infuses them into a classic pot roast. While it’s a bit of a fusion, the result is undeniably comforting and hearty, making it a fantastic twist on a traditional roast.

Let’s talk ingredients: the keys to this delicious French onion pot roast

Each ingredient here plays an important role in building flavor, so let’s go over them briefly.

• Beef chuck roast: Chuck roast is perfect for pot roasts because of its marbling. All that fat melts down as it cooks, giving you that tender, melt-in-your-mouth texture. If you can’t find chuck roast, a brisket or rump roast works too, though it may have a slightly different texture.
• Steak seasoning and kosher salt: These add a robust, savory flavor to the beef. If you’re out of steak seasoning, a mix of garlic powder, black pepper, paprika, and a bit of cayenne works well as a substitute.
• Garlic: Fresh garlic adds depth to the overall flavor. If you’re in a pinch, garlic powder will do, but fresh is always better in this dish.
• Onions: White or yellow onions work beautifully here, giving a slightly sweet, caramelized flavor as they cook down with the meat.
• Beef broth and Better Than Beef Bouillon: The broth is the base of your gravy, while the bouillon adds extra depth. If you don’t have bouillon, you can use a bit more broth, but you might miss out on that concentrated beefy flavor.
• Bay leaf: This herb is subtle but adds a lovely, earthy undertone. Just one is enough – you don’t want to overpower the dish.
• Cornstarch: This helps thicken the gravy at the end. You could use flour if you prefer, but cornstarch is quick and keeps the sauce glossy.

Kitchen gear: what you need (and what you can totally skip)

To make this pot roast, you’ll obviously need an Instant Pot (or any pressure cooker). If you’re new to pressure cooking, don’t worry – it’s easier than it seems, and this recipe is very forgiving. Beyond the Instant Pot, you’ll just need a few basic tools:

• Tongs: Useful for handling the beef chunks. Since we’re cutting the roast into pieces, tongs make it easier to move them around.
• A mixing bowl: For making the cornstarch slurry.
• A wooden spoon or spatula: For stirring the gravy on sauté mode. I prefer wooden utensils because they’re gentle on the Instant Pot’s inner pot and don’t scratch it.

Step-by-step: my foolproof method (and a few hard-learned lessons)

Alright, let’s get cooking! Here’s how to make this French onion pot roast, step by step.

1. Prep the meat
   Start by cutting your chuck roast into roughly 10 pieces. This helps it cook evenly in the Instant Pot and makes it easier to shred later. Generously season the pieces with steak seasoning and kosher salt.
2. Load up the Instant Pot
   Place the meat in the Instant Pot’s inner pot, then pour in 1 ¼ cups of beef broth. Sprinkle the minced garlic over the top, then pile on the sliced onions. These will cook down and infuse everything with their sweet, savory flavor.
3. Add bouillon and bay leaf
   Drop in a tablespoon of Better Than Beef Bouillon and a bay leaf. Trust me, the bouillon is magic here – it really boosts that beefy flavor.
4. Seal and cook
   Lock the lid in place and make sure the pressure release valve is set to sealing. Set the Instant Pot to manual high pressure for 60 minutes. Once it’s done, let the pressure release naturally for 25 minutes (this helps keep the meat tender).
5. Shred the meat
   Once you can safely open the lid, take out the beef chunks and shred them with two forks. They should come apart easily! Also, remove and discard the bay leaf.
6. Thicken the gravy
   For the gravy, mix ¼ cup of beef broth with 2 tablespoons of cornstarch in a small bowl. Set the Instant Pot to sauté mode, stir in the cornstarch mixture, and cook for about 2 minutes, stirring regularly, until the sauce thickens.
7. Serve
   Pour that luscious gravy over the shredded beef and serve it up warm. You can serve this with mashed potatoes, rice, or crusty bread – anything to soak up that delicious sauce.

Variations and adaptations: make it your own!

There are plenty of ways to adapt this recipe to suit your tastes or dietary needs:

• Low-carb/Keto: Skip the cornstarch and enjoy the broth as is, or add a tiny sprinkle of xanthan gum to thicken.
• Vegetarian version: Substitute the beef with large portobello mushrooms and use vegetable broth. You won’t get quite the same flavor, but it’s still delicious!
• Spicy twist: Add a pinch of red pepper flakes or a splash of hot sauce to give it a bit of heat.
• French flair: Top with a sprinkle of Gruyère cheese and broil until bubbly. It’s a nod to classic French onion soup and adds a decadent, melty layer of flavor.
• Seasonal add-ins: Toss in carrots or parsnips for extra heartiness, or even mushrooms for an earthy flavor boost.

How to serve it (and impress your guests)

Serve this pot roast with mashed potatoes or creamy polenta for a hearty, comforting meal. If you want to make it feel extra special, sprinkle fresh parsley over the top for a pop of color. This dish also pairs beautifully with crusty bread – perfect for mopping up that rich, oniony gravy. And if you’re having guests, consider serving it family-style on a big platter, with the gravy poured over the shredded meat for a rustic, inviting presentation.

Drink pairings for a cozy meal

A rich red wine like Cabernet Sauvignon or Merlot pairs wonderfully with this dish, cutting through the richness of the beef and complementing the sweetness of the onions. If you’re more of a beer drinker, try a dark ale or stout – something with enough body to stand up to the flavors. For a non-alcoholic option, a sparkling apple cider adds a bit of brightness that works surprisingly well with the savory flavors.

Storage and reheating tips

Leftovers? Lucky you! This pot roast tastes even better the next day. Store any leftovers in an airtight container in the fridge for up to 4 days. To reheat, you can either microwave individual portions or warm it on the stovetop over low heat, adding a splash of beef broth if needed to keep it moist. If you want to freeze it, make sure to store the meat and gravy separately for up to 3 months.

Scaling the recipe for a crowd (or just for two)

This recipe scales up or down quite easily. For a larger crowd, simply add more meat and increase the other ingredients proportionally. Just be mindful not to overfill the Instant Pot – it should be no more than two-thirds full. For a smaller portion, you can cut the recipe in half, keeping the same cook time.

Common questions about Instant Pot French onion pot roast

Q: Can I use frozen beef?
A: Yes, but it will take longer to come to pressure. Increase the cook time to 75 minutes.

A: Absolutely! Use a slow cooker on low for 8 hours or a Dutch oven in the oven at 325°F for 3-4 hours.

Q: Can I skip the bouillon?
A: You can, but the bouillon adds an extra punch of flavor. If skipping, consider adding a bit more salt.

Q: What can I use instead of cornstarch?
A: Flour works as a thickener, but mix it with cold water first to avoid lumps.

Q: Do I have to cut the roast into chunks?
A: Cutting it speeds up cooking and makes shredding easier. You can leave it whole, but increase the cook time by 10-15 minutes.

In the end, this Instant Pot French onion pot roast is all about comfort and flavor. Give it a try, experiment with it, and make it your own. Whether it’s a cozy weeknight meal or a special occasion, this dish is sure to impress. Enjoy!
