What You'll Need & Why

• Chuck roast: The best cut for pot roast, becoming tender and flavorful as it cooks.
• Onions, garlic, and thyme: The foundation of the classic French onion flavor that gives this roast its signature character.
• Tomato paste, Worcestershire sauce, and mushroom powder: Build deep, savory flavor and help create a rich, beefy gravy.
• White wine and beef broth: Form the cooking liquid that transforms into the onion gravy.
• Avocado oil, kosher salt, black pepper, and bay leaves: Simple pantry staples that round out the flavor and help everything cook beautifully.

The Recipe Rundown

• Sear the roast: Brown the chuck roast on all sides to build deep flavor before pressure cooking.
• Build the onion gravy: Cook the tomato paste, onions, wine, and seasonings until everything is rich, savory, and fragrant.
• Pressure cook until tender: Return the roast to the pot, add the broth, and cook until the beef is fall-apart tender.
• Shred and serve: Remove the roast, shred it, and spoon the rich French onion gravy over the top.
• Don't skip the gravy: Serve with mashed potatoes, egg noodles, or cheesy Gruyère toasts to soak up every last drop.

Swaps & Variations

This French Onion Pot Roast is easy to customize while keeping all that rich, savory flavor.

• Skip the wine: Replace it with additional beef broth for a family-friendly version.
• Add mushrooms: Cremini or baby bella mushrooms add even more savory, umami flavor.
• Double the onions: If you're a true French onion lover, add an extra onion for an even richer gravy.
• Switch up the cheese: Gruyère is classic, but Swiss, provolone, or fontina work beautifully on the toasts.

Tips For The Best French Onion Pot Roast

A few simple tips will help your French Onion Pot Roast turn out rich, flavorful, and fall-apart tender.

• Sear the roast well: Deep browning creates the foundation for a richer, more flavorful gravy.
• Cook the onions until softened: Taking a little extra time here helps build that classic French onion flavor.
• Deglaze the pot: Scrape up the browned bits after adding the wine or broth—they add incredible depth to the gravy.
• Use a meat thermometer or fork test: The roast is done when it's easily shredded and fork-tender.
• Let it rest before shredding: A few minutes of rest helps the beef stay juicy and easier to pull apart.

Slow Cooker Instructions

This French Onion Pot Roast is just as easy in the slow cooker. Add all ingredients and cook on LOW for 7–8 hours or HIGH for 5–6 hours, until the beef is fork-tender and easily shreds apart.

Tip: For the best flavor, sear the roast before adding it to the slow cooker.

Dutch Oven Instructions

For a classic low-and-slow approach, use a Dutch oven. Follow the same steps to sear the beef and build the onion gravy, then cover and cook in a 250°F oven for 6–8 hours, or until the roast is fall-apart tender.

• Simple Green Salad: A fresh, crisp contrast to the rich beef and gravy.
• Roasted Brussels Sprouts: Add a little color and balance while keeping dinner easy.
• Dutch Oven No-Knead Bread: Perfect for mopping up every last drop of gravy from the plate.

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Reheating: Warm gently on the stovetop or in the microwave until heated through. Add a splash of beef broth if the gravy thickens.
• Freezing: This pot roast freezes well. Store cooled beef and gravy in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
