Key Ingredients & Substitutions
Beef Chuck Roast: This cut is perfect for pot roast due to its rich flavor and tenderness when slow-cooked. If you can’t find chuck roast, a brisket or round roast can work, but they may not be as juicy.
Yellow Onions: These onions are sweet and caramelize beautifully, enhancing the dish’s flavor. You can substitute with sweet onions or even red onions, but they have a milder taste.
Garlic: Fresh garlic adds a wonderful aroma. If you’re short on fresh, you can use garlic powder; just 1/2 teaspoon should suffice.
Beef Broth: I recommend low-sodium beef broth for better salt control. If you want to lighten things up, vegetable broth works too, but it changes the flavor slightly.
Dry White Wine: Optional, but it adds depth to the dish. If you prefer not to use wine, just replace it with more broth or even a splash of apple cider vinegar for acidity.
How Do You Achieve Perfectly Caramelized Onions?
Caramelizing onions can elevate your dish! Here’s how to do it right:
- Heat a skillet over medium heat and add olive oil.
- Once hot, add the thinly sliced onions, stirring to coat them in oil.
- Cook them slowly, stirring often, for about 15-20 minutes until they’re soft and deeply brown.
- Patience is key! If you rush, they might burn instead of caramelize.
This process brings out their natural sweetness, making your pot roast even more delicious!

Ingredients You’ll Need:
For the Roast:
- 3 to 4 pounds beef chuck roast
- Salt and freshly ground black pepper, to taste
- 2 tablespoons olive oil
For the Onion Mixture:
- 4 large yellow onions, thinly sliced
- 4 garlic cloves, minced
- 1 teaspoon dried thyme (or 2 teaspoons fresh thyme leaves)
- 1 tablespoon Worcestershire sauce
- 1 cup beef broth
- 1/2 cup dry white wine (optional; can substitute with extra beef broth)
- 1 bay leaf
For the Vegetables:

How Much Time Will You Need?
This delicious meal takes about 30 minutes of hands-on preparation time. Then, just let it cook in the crockpot! On low, it will take about 8 to 10 hours, or if you’re in a hurry, 4 to 5 hours on high. Perfect for a busy day!
Step-by-Step Instructions:
1. Season the Roast:
Generously season the beef chuck roast with salt and freshly ground black pepper all over. This will enhance the flavor of the meat as it cooks.
2. Sear the Roast:
In a large skillet, heat the olive oil over medium-high heat. Once the oil is hot, sear the roast for about 3-4 minutes per side until it’s nicely browned. This step adds flavor! Once browned, carefully transfer the roast to your crockpot.
3. Caramelize the Onions:
In the same skillet, add the thinly sliced onions. Cook them over medium heat, stirring frequently, until they are caramelized and golden brown, which usually takes around 15-20 minutes. This step gives the dish its signature flavor.
4. Add Garlic and Seasonings:
Once the onions are caramelized, add minced garlic and thyme. Stir and cook for about a minute until it becomes fragrant. Then, add the Worcestershire sauce, beef broth, and white wine (if using). Scrape any browned bits off the bottom of the skillet as they are packed with flavor!
5. Combine in the Crockpot:
Pour the onion mixture over the roast in the crockpot and add the bay leaf for extra aroma and flavor.
6. Add Vegetables:
Next, scatter the halved baby potatoes and chunks of carrots around the roast in the crockpot. This will ensure they absorb all the delicious flavors as they cook.
7. Slow Cook:
Cover the crockpot and cook on low for 8 to 10 hours, or on high for 4 to 5 hours. You’ll know it’s ready when the roast is fork-tender, and the vegetables are soft.
8. Final Touch:
Before serving, be sure to remove the bay leaf. Spoon some of the rich French onion gravy and caramelized onions over the roast and vegetables for added flavor.
9. Garnish and Serve:
Garnish with fresh thyme sprigs for a pretty presentation and serve your delicious pot roast hot. Enjoy every comforting bite!
