Ingredients

• Chuck Roast: Choose a well-marbled chuck roast for the best flavor and tenderness. The fat will render down during cooking, creating a melt-in-your-mouth texture.
• Olive Oil: Use a good quality olive oil for searing to help develop a flavorful crust on the meat.
• Onions: Yellow or sweet onions work best for this recipe as they caramelize beautifully and provide the signature French onion flavor.
• Garlic: Fresh garlic cloves add aromatic depth to the dish—feel free to adjust the amount based on your preference.
• Beef Broth: Use low-sodium beef broth to control the salt level, or for enhanced flavor, try homemade beef stock.
• White Wine: A dry white wine like Sauvignon Blanc or Pinot Grigio adds acidity and complexity. Can be substituted with additional broth for an alcohol-free version.
• Thyme: Fresh thyme provides earthy, aromatic notes that complement beef perfectly, but dried thyme works as a convenient alternative.
• Worcestershire Sauce: This umami-rich condiment adds depth and a subtle tanginess to the dish.
• Bay Leaves: These aromatic leaves infuse the broth with subtle flavor during the pressure cooking process.
• Gruyère Cheese: This nutty, melty Swiss cheese is traditional for French onion flavor, but can be omitted or substituted with provolone or Swiss.
• Fresh Parsley: Adds a bright, fresh note as a garnish to balance the rich flavors of the dish.

Variations

Wine-Free Version

Create an equally delicious alcohol-free version by replacing the white wine with additional beef broth or apple juice. For extra tang, add a tablespoon of balsamic vinegar to mimic some of the complexity that wine brings to the dish.

Italian-Style Pot Roast

Transform this French-inspired dish into an Italian version by substituting the white wine with red wine, adding a can of diced tomatoes, and swapping the thyme for Italian herbs like rosemary, oregano, and basil. Top with shredded Parmesan instead of Gruyère for an Italian twist.

Mushroom Lover’s Version

Enhance the umami flavor by adding 8 ounces of sliced mushrooms (cremini, button, or a mix) when cooking the onions. The mushrooms will complement the caramelized onions and create an even more robust flavor profile that pairs beautifully with the tender beef.

How to Make the Recipe

Step 1: Sear the Meat

Begin by setting your Instant Pot to “Sauté” mode and add olive oil to the pot. While the oil heats, generously season your chuck roast with salt and pepper on all sides. Once the oil is hot and shimmering, carefully place the roast in the pot and sear until a deep brown crust forms on each side, approximately 4-5 minutes per side. This crucial step creates the foundation of flavor for your dish. Once seared, remove the roast and set it aside temporarily.

Step 2: Caramelize the Onions

Add your thinly sliced onions to the same pot, taking advantage of the flavorful fond (browned bits) left from searing the meat. Cook the onions over medium heat, stirring occasionally to prevent burning, until they transform from white to golden brown and develop a sweet, caramelized flavor—this process takes patience, about 10-15 minutes. In the final minute, add the minced garlic and stir continuously to prevent it from burning while it releases its aromatic qualities.

Step 3: Deglaze and Pressure Cook

Pour the white wine (or additional broth) into the hot pot and use a wooden spoon to scrape up all the flavorful browned bits from the bottom—this step is essential for flavor and prevents the “burn” warning on your Instant Pot. Return the seared roast to the pot and add beef broth, thyme, Worcestershire sauce, and bay leaves. Secure the lid, ensuring the valve is set to “sealing,” and select “Manual” or “Pressure Cook” on high for 60 minutes. Once cooking completes, allow a natural pressure release for 15 minutes before carefully releasing any remaining pressure.

Step 4: Finish and Serve

After the pressure has fully released, open the lid and remove the bay leaves. Transfer the roast to a serving platter and shred it using two forks—it should be tender enough to fall apart easily. Taste the sauce and adjust seasonings if needed. Serve the shredded beef topped with the caramelized onions and cooking liquid, and if desired, sprinkle with shredded Gruyère cheese and let it melt slightly from the heat of the meat. Garnish with fresh parsley for a pop of color and freshness.

Tips for Making the Recipe

• Don’t rush the searing process—a proper sear creates depth of flavor that makes all the difference
• Slice onions to uniform thickness to ensure even caramelization
• If you have time, caramelize the onions longer (20-30 minutes) for an even deeper flavor profile
• Make sure to fully deglaze the pot before pressure cooking to avoid the “burn” notice
• For a thicker sauce, after pressure cooking, remove the meat and set the Instant Pot to “Sauté” to reduce the liquid
• Let the roast rest for 5-10 minutes before shredding for juicier meat

How to Serve

This French Onion Pot Roast makes a stunning presentation when served family-style on a large platter with the caramelized onions spooned over the shredded beef. For the authentic French onion experience, place portions in oven-safe bowls, top with Gruyère cheese, and broil briefly until the cheese is melted and bubbly.

Serve with crusty bread to soak up the delicious juices, or pair with creamy mashed potatoes or buttered egg noodles. For a complete meal, add a simple green salad dressed with a light vinaigrette or roasted vegetables to balance the richness of the dish. A glass of the same white wine used in cooking makes a perfect accompaniment.

Make Ahead

This French Onion Pot Roast actually improves with time, making it perfect for make-ahead meal planning. You can prepare the entire dish up to 3 days in advance and store it in an airtight container in the refrigerator. The flavors will continue to develop and meld together, creating an even more delicious meal when reheated.

For longer storage, freeze the completely cooled pot roast with its sauce in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating. To reheat, place in a covered pot on the stovetop over medium-low heat or in the Instant Pot on “Slow Cook” until warmed through, adding a splash of beef broth if needed to maintain moisture.

FAQs

Can I make this in a slow cooker instead of an Instant Pot?

Yes! This recipe adapts beautifully to a slow cooker. Sear the meat and caramelize the onions in a separate pan on the stovetop, then transfer everything to your slow cooker. Cook on low for 8-10 hours or on high for 4-5 hours until the meat is tender and easily shreddable.

What can I substitute for white wine?

If you prefer not to use alcohol, simply replace the white wine with additional beef broth. For added acidity and complexity, stir in 1-2 tablespoons of white wine vinegar or a splash of apple cider vinegar.

My meat isn’t as tender as I expected. What went wrong?

Chuck roast needs adequate cooking time to break down its connective tissues. If your meat isn’t tender after the recommended cooking time, it likely needs more time. Return it to the Instant Pot and cook under pressure for an additional 10-15 minutes, followed by another natural release.

Can I add vegetables like carrots and potatoes to this recipe?

Absolutely! For best results, pressure cook the meat as directed, then add chunked carrots and potatoes after releasing the pressure. Reseal the pot and pressure cook for an additional 4-5 minutes. This prevents the vegetables from becoming overly soft during the long cooking time needed for the beef.

Conclusion

This Instant Pot French Onion Pot Roast elevates comfort food to a new level by combining two beloved classics. The pressure cooker method transforms an all-day cooking project into a manageable weeknight meal without sacrificing flavor or tenderness. With its rich, savory sauce, melt-in-your-mouth beef, and sweet caramelized onions, this dish is sure to become a favorite in your recipe collection.
