For the Caramelized Onions:

- 2 cloves garlic, minced
- 1 tbsp maple syrup or brown sugar
- 1 tbsp all-purpose flour (or gluten-free alternative)
- 2 tbsp extra virgin olive oil

How to Make French Onion Pot Roast
Step 1: Sear the Chuck Roast
Preheat a Dutch oven over medium heat and add 1 tablespoon of olive oil. Season the chuck roast with salt and pepper, then sear it on all sides until beautifully browned—about 10–12 minutes total. This step locks in flavor and gives you those delicious browned bits that make the sauce so irresistible.
Transfer the roast to a plate and set aside.
Step 2: Prepare and Cook the Onions
While the roast rests, add 2 tablespoons of olive oil to the same pot. Toss in your mountain of sliced onions and season with salt and pepper. Cook over medium heat, stirring frequently, until they start to soften (about 5 minutes). Then reduce the heat to medium-low and let them cook gently for 20 more minutes, stirring occasionally until golden and sweet. Patience is key here—caramelized onions are worth every minute.
Step 3: Caramelize and Build the Sauce
Add minced garlic and maple syrup (or brown sugar) to the onions. Cook for another 7–8 minutes until everything smells like heaven. Sprinkle in the flour, stirring to coat the onions evenly. Slowly pour in the beef stock, scraping the bottom of the pot to get all that flavor goodness into the sauce. Stir well until smooth.
Give it a taste—if it needs a little extra salt, go for it. You’re the boss here.
Step 4: Simmer and Braise the Roast
Return the seared roast to the Dutch oven, nestling it into the onion mixture. Add rosemary and bay leaf. Bring to a gentle simmer, then cover and transfer to a 300°F oven. Let it braise undisturbed for 3 hours.
After that, give it a quick turn with tongs, breaking it into a few large chunks (it should be super tender by now). Cover again and cook another 30–45 minutes until it’s fork-tender and perfect.
Step 5: Cool, Rest, and Serve
Once done, let the roast rest a bit before serving. If you can resist diving in immediately, refrigerate it overnight and reheat the next day—the flavors deepen beautifully. Serve hot over mashed potatoes, polenta, or buttered egg noodles, spooning plenty of that rich onion gravy on top.

Aneta’s Kitchen Tips
- Patience is everything. Caramelizing onions takes time, but rushing them will rob you of that deep, sweet flavor.
- Make it ahead. This dish tastes even better the next day, so it’s perfect for Sunday meal prep.
- No wine? No problem. Stick with extra beef stock—the flavor will still be incredible.
- Leftovers? Shred the beef and turn it into French onion beef sandwiches with melted provolone on toasted rolls. You’re welcome.
FAQs About French Onion Pot Roast
Can I make this in a slow cooker?
Absolutely! Just sear the beef and caramelize the onions first on the stove, then transfer everything to your slow cooker. Cook on low for 8–9 hours.
Can I skip the flour?
You can! The sauce will be slightly thinner but still delicious. If you need to thicken it, whisk in a teaspoon of cornstarch with a bit of water at the end.
How do I store leftovers?
Store the roast and sauce together in an airtight container in the fridge for up to 4 days, or freeze for up to 3 months.
