Ingredient Notes
-
Chuck Roast (3–4 lbs): Well-marbled beef is ideal for slow cooking, ensuring tender, juicy results. Substitute with brisket if preferred.
-
Yellow Onions (4 large): Sweet, caramelized onions provide the signature French onion flavor. Can mix with red onions for extra color.
-
Beef Broth (2 cups): Adds depth to the gravy. Low-sodium is recommended to control saltiness.
-
Butter (3 tbsp): Enhances onion flavor; can substitute with olive oil for a lighter version.
-
Garlic (4 cloves): Adds aromatic richness. Roasted garlic can be used for a milder, sweeter flavor.
-
Worcestershire Sauce (2 tbsp): Boosts umami and depth of flavor. Soy sauce is an acceptable substitute.
-
Thyme & Bay Leaves: Essential for a classic French onion aroma. Fresh thyme gives the best flavor, but dried works fine.
-
Flour (2 tbsp): Thickens the gravy; cornstarch slurry can be used for a gluten-free option.
-
Optional Equipment: Dutch oven or slow cooker for even, tender cooking.
How To Make Comforting French Onion Pot Roast

-
Preheat and prepare the onions
-
Slice onions thinly and sauté in butter over medium heat until deeply caramelized (about 20–25 minutes).

Tip: Stir frequently to avoid burning. Low and slow is key for sweet, golden onions.
-
-
Sear the beef
-
Pat roast dry and season generously with salt and pepper.
-
Sear on all sides in a hot skillet for 3–4 minutes per side to lock in juices.
-
-
Layer in Dutch oven or slow cooker

Spread half of the caramelized onions at the bottom. Place the seared roast on top, then cover with remaining onions.
-
-
Add liquids and seasonings
-
Pour beef broth and Worcestershire sauce over the roast. Add garlic, thyme, and bay leaves.
-
Optional: sprinkle flour over onions for a thicker gravy.
-
-
Cook low and slow

Slow cooker method: Cook on low for 6–8 hours.
-

Finish the gravy
