How to Make Instant Pot French Onion Pot Roast Recipe

Step 1: Caramelize the Onions

Begin by setting your Instant Pot to the sauté function. Add a little oil, then toss in the sliced onions. Stir them frequently until they turn a gorgeous deep golden brown. This caramelization is the soul of the dish, creating that rich, slightly sweet base you want. Once done, remove the onions and set them aside.

Step 2: Sear the Beef Roast

Now it’s time to get some color on your roast. Season the beef chuck with salt and pepper, then sear it on all sides right in the Instant Pot until you have an irresistible browned crust. This not only locks in juices but adds that fantastic savory note to your pot roast.

Step 3: Add Aromatics and Liquids

Return the caramelized onions to the pot along with the minced garlic cloves, beef broth, Worcestershire sauce, and thyme. Scrape the bottom of the pot gently to deglaze it—that means picking up any tasty browned bits stuck from searing. These bits are flavor gold and will enrich your sauce beautifully.

Step 4: Pressure Cook to Perfection

Seal the Instant Pot lid and set it to cook on HIGH pressure for 60 minutes. After the cooking time is up, let it naturally release the pressure—it’s worth waiting for that slow softening and melding of flavors. Your roast will be fall-apart tender, ready to be shredded perfectly.

Step 5: Shred and Serve

Carefully remove the roast and shred it using two forks. Return the shredded beef back into the pot to soak up the rich onion sauce before scooping it onto your plate. Now you have a gorgeous meal that’s bursting with those classic French onion soup vibes combined with the heartiness of pot roast.

Garnishes

Fresh parsley or a sprinkle of chopped thyme adds a pop of color and fresh herbal brightness, which beautifully balances the rich sauce. You can also top it with a few sautéed mushrooms for an earthy twist or even a dash of shredded Gruyère cheese if you’re feeling indulgent.

Side Dishes

This pot roast is perfect alongside creamy mashed potatoes that soak up the luscious onion gravy, or crusty artisan bread for dipping. Steamed green beans or roasted root vegetables offer great textural contrast and complete the meal with wholesome flavors.

Creative Ways to Present

Why not elevate this comforting classic by serving it over buttered egg noodles or creamy polenta for a cozy yet elegant dinner? For a casual feast, pile the shredded beef inside toasted baguette slices for a hearty sandwich. The possibilities are endless, and each presentation highlights different textures and tastes in delicious ways.

Make Ahead and Storage

Storing Leftovers

After enjoying your pot roast, store any leftovers in an airtight container in the fridge for up to 4 days. The flavors deepen even more after a day or two, making your next meal just as delightful.

Freezing

This Instant Pot French Onion Pot Roast Recipe freezes beautifully. Portion the shredded meat and sauce in freezer-safe bags or containers, and freeze for up to 3 months. Thaw overnight in the fridge before reheating for an easy, quick meal anytime.

Reheating

Reheat leftovers gently on the stove over medium-low heat or in the microwave, stirring occasionally. Adding a splash of beef broth can help prevent drying out and keep that luscious sauce perfectly silky.

FAQs

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

Absolutely! While beef chuck roast is ideal for tenderness and flavor, you can also use brisket or bottom round. Just keep in mind that cooking times may vary slightly to reach the perfect tenderness.

Is it necessary to caramelize the onions first?

Caramelizing the onions brings out their natural sweetness and adds depth to the dish, which is key to achieving that distinct French onion flavor. Skipping this step will make the roast less rich and flavorful.

Can I add vegetables to the Instant Pot while cooking?

You can! Adding hearty vegetables like carrots and potatoes is a great idea, but place them on top of the roast so they cook evenly during pressure cooking. Keep in mind this may slightly adjust the cooking time.

Is this recipe gluten-free?

Yes, this Instant Pot French Onion Pot Roast Recipe is naturally gluten-free, just make sure your Worcestershire sauce is gluten-free, as some brands include gluten-containing ingredients.

Can I use dry thyme instead of fresh?

Yes, dry thyme works perfectly here, and it’s actually what the recipe originally calls for. Use about one teaspoon of dried thyme to infuse that lovely herbal aroma.
