Gather These Simple Ingredients
To make this delightful French Onion Pot Roast, you’ll need:
- 3 lbs boneless chuck roast, trimmed and patted dry
- 2 tsp kosher salt, plus more to taste
- 1 tsp freshly ground black pepper, plus more to taste
- 2 tbsp all-purpose flour
- 2 tbsp olive oil
- 3 lbs yellow onions (about 6 medium), thinly sliced into half-moons
- 6 garlic cloves, minced
- 1 cup low-sodium beef broth
- ½ cup dry white wine (or extra beef broth for non-alcoholic option)
- 2 tbsp Worcestershire sauce
- 2 bay leaves
- 1 tsp fresh thyme leaves (or ½ tsp dried thyme)
- 1 tbsp cornstarch (optional, for thickening)
- 1 tbsp cold water (optional, for thickening)
- Mashed potatoes or crusty bread, for serving
Let’s Make It Together
Here’s how to create this cozy, hearty meal:
Season the Roast: Generously season the chuck roast with kosher salt and freshly ground black pepper. Coat it with all-purpose flour to create a lovely crust.
Sear the Roast: In a cast-iron skillet over medium-high heat, heat olive oil. Sear the roast for 3-4 minutes on each side until it’s deep golden brown. Transfer the seared roast to the slow cooker.
Cook the Onions: In the same skillet, reduce the heat to medium, and add the sliced yellow onions. Cook for 8-10 minutes, stirring frequently, until they become soft and develop a pale golden color. Add in minced garlic and cook for an additional 30 seconds until fragrant.
Deglaze the Skillet: Pour in the white wine (or additional broth), scraping up those delicious browned bits from the bottom of the pan. Let it simmer for about 2 minutes until it’s reduced by half.
Combine Ingredients in the Slow Cooker: Pour the onion mixture over the roast. Then, add the beef broth, Worcestershire sauce, bay leaves, and thyme. Cover and cook on LOW for 8 hours or HIGH for 4 hours, until the roast pulls apart easily with forks.
Rest and Thicken: Once cooked, transfer the roast to a cutting board and tent with foil. Let it rest for 10 minutes. Remove and discard the bay leaves from the cooker. If you prefer a thicker sauce, mix cornstarch with cold water to create a slurry, then stir it into the sauce and cook on HIGH for an additional 10-15 minutes until thickened.
Serve: Shred or slice the rested roast, top generously with the onion sauce, and serve alongside creamy mashed potatoes or crusty bread. Season with extra salt and pepper to taste.
Delicious Variations to Try
- Mushroom Medley: Add sliced mushrooms when cooking the onions for an earthy, rich flavor that elevates the dish further.
- Herb Infusion: Mix in fresh rosemary or parsley for a bright, aromatic twist that complements the savory flavors beautifully.
- Vegetable Add-Ins: Toss in some carrots or potatoes into the slow cooker for added nutrition and heartiness in the dish, ensuring everything cooks together in perfect harmony.
- Spicy Kick: Add a pinch of red pepper flakes for a subtle heat that balances the richness of the pot roast.
Chef Emma’s Helpful Tips
- Make Ahead: This pot roast actually gets better with time! You can prepare it a day in advance and simply reheat it for an easy dinner.
- Ingredient Swaps: Feel free to swap the dry white wine for more beef broth if you prefer a non-alcoholic version. The flavor will still be rich and satisfying!
- Leftover Storage: Store any leftovers in an airtight container in the fridge for up to 3 days. It also freezes beautifully for future meals.
- Slicing Trick: For the most tender slices, use a sharp knife and cut against the grain of the meat to ensure every bite is melt-in-your-mouth good.
