Choosing the Right Cut of Beef
Chuck roast is the gold standard for pot roast — it’s marbled, flavorful, and becomes tender when slow-cooked. Brisket or round roast can work too, but chuck roast guarantees melt-in-your-mouth results.

Step-by-Step Instructions
Step 1 – Searing the Roast for Flavor
Heat olive oil in your Dutch oven over medium-high. Pat the roast dry and season with salt and pepper. Sear on all sides until nicely browned (about 3-4 minutes per side). Remove and set aside.
Step 2 – Caramelizing the Onions Just Right
Add a bit more oil if needed. Toss in the sliced onions and cook on medium-low for 25–30 minutes, stirring occasionally. Add a pinch of salt and a bit of sugar if you want to speed up the caramelization.
Step 3 – Deglazing with Broth & Wine
Once onions are golden and jammy, stir in garlic and tomato paste. Cook for 1-2 minutes. Pour in wine to deglaze the pot, scraping up any browned bits. Let it simmer until wine reduces slightly, then add Worcestershire, broth, thyme, and bay leaf.
Step 4 – Slow Cooking to Tender Perfection
Return the seared roast to the pot. Cover with a lid and transfer to a preheated oven at 325°F (163°C). Braise for 3 to 3.5 hours until the beef is fork-tender.
Step 5 – Thickening the Sauce (Optional)
Remove the beef. If the sauce is too thin, simmer it uncovered on the stove to reduce or mix in a cornstarch slurry (1 tbsp cornstarch + 2 tbsp water) to thicken.

Cooking Method Variations
Oven-Braised French Onion Pot Roast
Best for maximum flavor. The oven’s even heat slowly breaks down the meat and intensifies the sauce.
Slow Cooker Method
Sear beef and caramelize onions first, then add everything to the slow cooker. Cook on low for 8 hours or high for 5-6 hours.
Instant Pot Method
Use sauté mode to brown meat and cook onions. Pressure cook on high for 60–70 minutes with natural release.
Tips for the Best Flavor
Caramelized onions are the heart of this recipe. Low and slow wins the race — resist turning the heat too high.
Don’t Rush the Onions
Season Generously
Beef needs salt to shine, and don’t forget the garlic, thyme, and Worcestershire for deep flavor.
Let It Rest Before Slicing
Once cooked, let the roast sit for 10–15 minutes before slicing to keep juices locked in.
