How to Make French Onion Pot Roast Recipe

Step 1: Prepare and Season the Roast

The journey to a perfect French Onion Pot Roast Recipe begins with bringing your chuck roast to room temperature; this ensures it cooks evenly. Next, create the flavorful coating by combining salt, pepper, dried parsley, dried thyme, and the majority of your arrowroot starch. Rolling your roast in this mixture helps to create a delicious crust and locks in moisture during roasting.

Step 2: Sear the Roast to Lock in Juices

Heat the avocado oil in a Dutch oven until shimmering. Sear the roast on all sides until it develops a golden-brown crust, which not only adds incredible flavor but also helps keep the meat juicy. This step is worth the extra attention because it forms the foundation for a rich and hearty roast.

Step 3: Sauté the Onions and Garlic

Reduce heat to medium-low and add coconut aminos to deglaze the pot, scraping the flavorful browned bits off the bottom. Then, add your thinly sliced onions, tossing them to get coated in the coconut aminos. Slowly cook the onions until softened and fragrant, stirring occasionally so they become rich and sweet without burning. Add minced garlic toward the end for a milder, melded flavor.

Step 4: Combine Roast and Cooking Liquids

Clear a space in your pot and nestle the seared roast back among the onions. Pour in the beef broth and red wine vinegar, then tuck the bay leaves on top. Cover the pot with its lid and prepare to let the oven work its magic.

Step 5: Roast Low and Slow

Start roasting at 400°F for 30 minutes; this temperature jump jumpstarts flavor development. After that, reduce the oven to 300°F and let the tender transformation happen over 3 to 3.5 hours, depending on your roast size. Watch for that internal temperature between 185-195°F — that’s when the chuck roast becomes perfectly tender and fall-apart delicious.

Step 6: Thicken the Onion Gravy

Once the roast is ready and bay leaves removed, it’s time to thicken the cooking liquid. Mix the remaining arrowroot starch with cold water until smooth, then slowly stir into the hot juices in the pot. This simple step brings the sauce to a beautiful silky thickness, highlighting the caramelized onion flavors.

Step 7: Rest and Serve

Resting the roast allows juices to redistribute, ensuring every forkful is moist and flavorful. After 10 to 15 minutes, shred or slice the meat, spoon over that luscious onion gravy, and finish with fresh parsley and thyme for a stunning presentation.

Freezing

FAQs

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

Chuck roast is ideal because it becomes tender and flavorful when slow-cooked, but you can also use brisket or round roast. Just keep in mind that cooking times may vary to achieve the same tenderness.

Is there a substitute for coconut aminos?

Yes, soy sauce or tamari can be used as a substitute if you are not avoiding gluten or soy. For those who need to avoid soy, a bit of Worcestershire sauce or homemade beef broth concentrate can work as well.

How can I caramelize onions more deeply?

Cook onions slowly over low heat and be patient. Stir often to prevent burning, and add a pinch of sugar or a splash of vinegar to aid in caramelization and balance the flavors.

Can this dish be made in a slow cooker?

Absolutely! After searing and sautéing the onions, transfer everything to a slow cooker and cook on low for 7-8 hours for tender, flavorful results similar to the oven method.

What should I do if the gravy is too thin?

If your onion gravy needs thickening after reheating, whisk together a small amount of arrowroot starch or cornstarch with cold water and stir it into the hot liquid, cooking until thickened.
