Ingredients You’ll Need

Gathering the ingredients for this pot roast is simple, but each one plays a crucial role in building the rich flavors and textures that make the dish stand out. From the tender chuck roast to the aromatic onions and savory broth, every component makes the final dish truly delicious.

• 3 pounds boneless beef chuck roast cut into 10 chunks: This cut becomes wonderfully tender under pressure and absorbs flavors easily.
• 3 tablespoons steak seasoning: I love using a bold blend like Montreal steak seasoning to intensify the taste.
• 1 teaspoon kosher salt: Enhances all the flavors but can be omitted if your steak seasoning is already salty.
• 4 cloves garlic minced: Adds that irresistible savory depth that complements the beef perfectly.
• 2 large white or yellow onions sliced: The star of the French onion flavor profile, caramelizing down into sweet, tender goodness.
• 1 ½ cups reduced-sodium beef broth divided: Essential for the cooking liquid and gravy, choosing reduced sodium helps control saltiness.
• 1 tablespoon Better Than Beef Bouillon: Concentrates the beef flavor to make the broth extra savory and rich.
• 1 bay leaf: Adds a subtle herbal note that rounds out the broth’s complexity.
• 2 tablespoons cornstarch: Used to thicken the delicious broth into a luscious gravy at the end.

Directions

Step 1: Place the chuck roast chunks into the Instant Pot’s inner pot in an even layer. This will ensure even cooking and flavor absorption.

Step 2: Sprinkle the steak seasoning and kosher salt evenly over the meat pieces. This seasoning forms the base of the deep, savory flavor.

Step 3: Pour 1 ¼ cups of the beef broth over the meat, providing moisture for pressure cooking and flavor infusion.

Step 4: Scatter the minced garlic on top of the meat, then carefully layer the sliced onions over the garlic. These onions will soften and caramelize under pressure, creating that classic French onion taste.

Step 5: Add the Better Than Beef Bouillon and the bay leaf to the pot. These ingredients enrich the broth, deepening the flavor.

Step 6: Close and lock the Instant Pot lid. Make sure the pressure release valve is set to sealing. Choose the manual or pressure cook setting on high and set the time for 60 minutes.

Step 7: When cooking completes, allow the pressure to release naturally for 25 minutes. This slow release helps keep the meat tender and juicy.

Step 8: Carefully unlock and remove the lid. Take out the meat pieces and shred them with two forks. Discard the bay leaf from the pot.

Step 9: In a small bowl, mix the remaining ¼ cup of beef broth with the cornstarch until smooth.

Step 10: Turn the Instant Pot to sauté mode, then stir in the cornstarch mixture. Cook for about 2 minutes while stirring frequently until the gravy thickens to your desired consistency.

Step 11: Pour the thickened gravy over the shredded meat, give everything a gentle stir, and serve immediately for the best experience.

Servings and Timing

This recipe serves about 6 people generously, making it ideal for family dinners or a small gathering. Prep time is approximately 15 minutes, mostly for chopping and seasoning, while the cook time is 60 minutes under pressure plus 25 minutes natural release. Including the sautéing to thicken the gravy and final assembly, total time comes around to 1 hour and 45 minutes. There’s no extensive resting time needed, though letting the meat sit for a few minutes before shredding can help retain juices.

How to Serve This Instant Pot French Onion Pot Roast Recipe

When I serve this French Onion Pot Roast, my favorite approach is to pair it with classic mashed potatoes or creamy polenta. Both sides soak up the luscious gravy beautifully, turning every bite into a flavorful celebration. Roasted root vegetables or green beans also add a nice textural contrast and a burst of color to the plate.

For garnish, I like to sprinkle some freshly chopped parsley or thyme over the pot roast to add a pop of fresh green and a mild herbal note. Presentation-wise, serving the shredded beef in a shallow dish with plenty of gravy spilling over creates a rustic yet inviting look. For portion sizing, about one to one and a half cups of meat per person feels just right as a hearty main course.

When it comes to beverages, a full-bodied red wine like Cabernet Sauvignon or Malbec complements the beef’s robust flavors perfectly. For a non-alcoholic option, a sparkling apple cider or even a simple iced tea with a squeeze of lemon works wonderfully. This dish shines at family dinners, holiday meals, or anytime you want to impress with minimal fuss, so serving it hot to warm is definitely the way to go.

Variations

I enjoy experimenting with this Instant Pot French Onion Pot Roast Recipe to fit different tastes and dietary needs. For instance, swapping the chuck roast with an arm roast or rump roast works beautifully if those cuts are what you have on hand. For a lower sodium option, I often reduce or omit the kosher salt and rely on the steak seasoning and bouillon for flavor balance.

If you prefer something gluten-free, just ensure your steak seasoning and bouillon are certified gluten-free—and substitute the cornstarch with arrowroot powder if you like. For a vegetarian twist, while you can’t really make a pot roast without meat, turning the broth and onion base into a hearty mushroom stew using meaty varieties like portobello or cremini is something I’ve tried and loved.

Lastly, if you want to change the cooking method, this recipe can translate to a slow cooker; just layer the ingredients similarly and cook on low for 8 to 10 hours. The Instant Pot method, however, gives me the best balance of tenderness and deep flavor in half the time, which is why it’s my go-to.

Storage and Reheating

Storing Leftovers

I recommend storing any leftover French Onion Pot Roast in airtight containers to preserve flavor and moisture. Glass containers with tight-fitting lids work best because they don’t absorb odors and can go straight into the fridge. Refrigerated leftovers will keep well for 3 to 4 days, so you can easily enjoy the next day’s meal without any loss of quality.

Freezing

This recipe freezes really well, making it perfect for meal prep. I suggest portioning the shredded meat and gravy into freezer-safe containers or heavy-duty zip-top bags. Be sure to remove as much air as possible to prevent freezer burn. It can be stored frozen for up to 3 months and thawed overnight in the fridge before reheating.

Reheating

The best way to reheat is gently on the stovetop over low to medium heat, stirring occasionally. This helps the meat stay tender and allows the gravy to regain its silky texture. Avoid microwaving abruptly, as it can cause uneven heating and dry out the meat. If using the microwave, heat in short bursts and stir frequently. Adding a splash of beef broth while reheating can also refresh the dish beautifully.

FAQs

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

Absolutely! While chuck roast is ideal because of its marbling and tenderness under pressure, arm roast, rump roast, or brisket can also work well. Just adjust cooking times slightly if your pieces are thicker or leaner.

Is it necessary to use beef bouillon?

I find that the beef bouillon really boosts the depth of flavor in the broth, but if you don’t have it on hand, you can use a little soy sauce or Worcestershire sauce as a substitute to enrich the taste.

Can I make this recipe vegan or vegetarian?

While the traditional pot roast relies on beef, you can adapt the French onion flavor by making a mushroom stew using a rich vegetable broth and sauteed mushrooms. It won’t be exactly the same, but the savory onion gravy is just as delicious.

How do I achieve the perfect gravy consistency?

Mix the cornstarch with cold beef broth before adding it to the hot pot, then stir continuously while sautéing to avoid lumps. Cook until it thickens slightly and coats the back of a spoon for the best texture.

Can I prepare this recipe ahead of time?

Yes! You can season and layer the ingredients in the Instant Pot insert the night before, cover, and refrigerate. When ready, just pop it into the Instant Pot and start cooking. This makes busy day meal prep incredibly simple.

Conclusion

I truly hope you give this Instant Pot French Onion Pot Roast Recipe a try—it’s been one of my favorite comfort food discoveries and never fails to impress. The way the savory onions, tender beef, and rich gravy come together in such a convenient way makes it a true winner for any day of the week.
