Make It Your Way

One of the best things about this French Onion Beef Pot Roast Recipe is how adaptable it is. Over time, I’ve enjoyed tweaking it to match whatever mood or pantry I’m working with, and you should too!

Variation: Sometimes I swap coconut aminos for a splash of Worcestershire sauce for a more traditional flavor; it’s equally delicious if you’re not avoiding soy.
Low-Sodium: Using low-sodium broth and cutting back on salt lets you control the seasoning exactly — perfect if you’re watching salt intake.
Veggie Add-ins: You can toss sliced carrots or mushrooms in with the onions for an extra veggie boost and more depth.
Slow Cooker Method: If you want to set it and forget it, you can brown the roast and onions on the stove, then transfer everything to a slow cooker for about 7 hours on low — just add the broth and vinegar before cooking.

Step-by-Step: How I Make French Onion Beef Pot Roast Recipe

Step 1: Season and Prep Your Roast

Start by letting the chuck roast come to room temperature for about 30 minutes—that helps it cook evenly. Then, in a large shallow bowl, combine salt, pepper, dried parsley, dried thyme, and 2 tablespoons of arrowroot starch. Coat the roast on all sides in this seasoned mixture; the arrowroot helps form a light crust when searing.

Step 2: Brown the Meat for Flavor

Heat your dutch oven over medium heat and add avocado oil. When the oil is shimmering, add the roast—sear for 2 to 4 minutes on each side until it’s nicely browned but not burnt. This step is key for developing that deep savory flavor. Set the roast aside on a clean plate to rest while you move on to the onions.

Step 3: Cook the Onions Just Right

Reduce the heat to medium-low and pour in your coconut aminos while scraping the bottom of the pot with a wooden spoon—that scrapes up all those tasty browned bits. Toss in the sliced onions and stir them around in the coconut aminos. Cook for 8 to 10 minutes until they soften but don’t fully caramelize. Sprinkle with salt and add the minced garlic, cooking for another few minutes to wake up their flavor.

Step 4: Combine and Roast Low and Slow

Push the onions to the side of your dutch oven and nestle the roast back in the center. Pour in the beef broth and red wine vinegar, and tuck bay leaves on top of the meat before covering with the lid. Pop the whole pot into the preheated oven at 400°F and roast for 30 minutes. Then, lower the oven temperature to 300°F and continue roasting for 3 to 3.5 hours—depending on the size of your roast—until the meat reaches an internal temp of about 185-195°F. It should be tender enough to shred easily.

Step 5: Thicken Your Sauce and Rest

Carefully remove the lid and discard the bay leaves. Combine 2 teaspoons of arrowroot starch with a tablespoon of water in a small bowl, whisking until smooth. Stir this mixture into the hot cooking liquid to thicken your sauce into a luscious glaze. Let the pot roast rest for 10 to 15 minutes before shredding and serving with plenty of oniony cooking liquid spooned on top, plus a sprinkle of fresh parsley and thyme.

Tips from My Kitchen

Room Temperature Roast: Letting your roast sit out before cooking ensures more even cooking and keeps it tender.
Don’t Skip Searing: Browning the meat seals in flavors and makes every bite taste richer.
Watch Those Onions: Cook them until just softened, not fully caramelized, to keep the sweet-tangy vibe that makes this recipe sing.
Arrowroot for Thickening: Using arrowroot starch instead of flour gives you a perfectly clear, shiny sauce without cloudiness or heaviness.

Garnishes

I love topping this pot roast with fresh parsley and thyme—they brighten the dish and add a lovely herbal note that balances the rich beef and onions perfectly. Sometimes a sprinkle of finely grated Gruyère or Swiss cheese is a dreamy finishing touch if you’re feeling indulgent.

Side Dishes

For sides, creamy mashed white sweet potatoes are my go-to—they add a subtle sweetness that pairs gorgeously with the savory roast. I also like serving some crispy cheese toast made with gluten-free bread and a layer of melted Gruyère for a little crunch. Roasted root vegetables or steamed green beans work well too if you want something lighter.

Creative Ways to Present

For a special dinner, I like serving this French Onion Beef Pot Roast Recipe in individual mini dutch ovens or ramekins, topped with extra caramelized onions and fresh herbs. It makes for a stunning presentation and keeps everyone’s portion warm. I’ve also served it over creamy polenta to switch things up—it’s always a crowd-pleaser.

Make Ahead and Storage

Storing Leftovers

I usually let the leftovers cool to room temperature before transferring them to an airtight container. Stored in the fridge, they last beautifully for up to 4 days. The flavors actually deepen overnight, so next-day pot roast is often even better!

Freezing

This recipe freezes exceptionally well. I portion the shredded beef with its cooking liquid into freezer-safe bags or containers, leaving some space for expansion. It keeps for around 3 months. When thawed, the meat remains moist and tender, just like fresh.

Reheating

To reheat, I gently warm the pot roast over low heat in a covered skillet or saucepan with a splash of broth to keep it juicy. You can also microwave leftovers covered with a damp paper towel to prevent drying out—just be sure to stir halfway through.

FAQs

Can I use a different cut of beef for this French Onion Beef Pot Roast Recipe?

Chuck roast is ideal because it has enough fat and connective tissue to become tender over slow cooking. However, you can use brisket or a bottom round roast—just be mindful that leaner cuts might be less juicy and could dry out without careful timing.
Is there a way to make this recipe dairy-free?

Absolutely! The recipe as shared is dairy-free. Just skip any cheese garnishes or sides like cheese toast. Instead, focus on serving it with mashed sweet potatoes or roasted veggies for a naturally dairy-free, hearty meal.
What can I substitute for arrowroot starch?

If you don’t have arrowroot, cornstarch also works for thickening the sauce. Use the same amount and mix with cold water before stirring into the hot liquid. Just keep in mind cornstarch may make the sauce slightly more opaque compared to arrowroot.
Can I prepare this recipe in a slow cooker instead of the oven?

Yes! After browning the roast and cooking the onions on the stove, transfer everything to your slow cooker with the broth and vinegar. Cook on low for 7-8 hours or until the meat is tender. Add the arrowroot mixture in the last 15-20 minutes to thicken the sauce.
How do I know when the roast is done?

The roast is perfectly done when its internal temperature hits between 185-195°F, making it tender enough to shred easily. Use a meat thermometer for best results to avoid undercooking or drying out the beef.
